134-611: Hout Bay ( Afrikaans : Houtbaai , meaning "Wood Bay") is a seaside suburb of Cape Town in the Western Cape province of South Africa . It is situated in a valley on the Atlantic seaboard of the Cape Peninsula , twenty kilometres south of the Central business district of Cape Town. The name "Hout Bay" can refer to the town, the bay on which it is situated, or the entire valley. The area
268-741: A Beehive shape frame made of pliable poles. The Khoi often set up camp in Hout Bay. The names Hotnotshuisie and Oudekraal originated from the days when the Khoi camped in these places. The Khoi traded with the early voyagers from Europe who were on their way to the East and had stopped at the Cape in order to get fresh food and water. The Khoi bartered with these early sailors exchanging cattle and sheep for small pieces of copper, brass and tin. The first written account of Hout Bay dates to 1607 when John Chapman, masters mate on

The South African Institute of Race Relations (SAIRR) projects that a growing majority of Afrikaans speakers will be Coloured . Afrikaans speakers experience higher employment rates than other South African language groups, though as of 2012 half a million were unemployed. Despite
670-483: A favourite camping site for many years before Flora Bay was developed. A large sandy beach, which linked up with the main beach, covered the rocks below this area. The sand slowly disappeared when the breakwater quays were built on the west side of the bay in 1937. A small beach was still there in the 1960s. The air pollution by the Oceana fishmeal factory in Hout Bay harbour has elicited a large number of complaints throughout

Other economically important manganese ores usually show a close spatial relation to the iron ores, such as sphalerite . Land-based resources are large but irregularly distributed. About 80% of the known world manganese resources are in South Africa; other important manganese deposits are in Ukraine, Australia, India, China, Gabon and Brazil. According to 1978 estimate,
1206-594: A line of forts known as the French lines that were built in order to protect the Cape from falling into the hands of the English. The west fort at the harbour dates from this time. In the latter half of the 19th century, the farms Moddergat, Nooitgedacht, Oakhurst and Uitkyk were established. In 1873, manganese was discovered in the Constantiaberg. In 1909 to 1911 manganese was mined in Hout Bay. Reminders of these activities are
1340-412: A low pass (now called Constantia Nek ) between the southern end of Table Mountain and Constantiaberg . Van Riebeeck described the forest of Hout Bay as being the finest in the world. It was Van Riebeeck who gave Hout Bay its present name. In 1652 on 22 November Van Riebeeck wrote in his journal about T’ Houtbaaitjen. Since then it has been known as Hout Bay. In 1662, the year when Jan Van Riebeeck left

Afrikaans is offered at many universities outside South Africa, including in the Netherlands, Belgium, Germany, Poland, Russia and the United States. In Afrikaans grammar, there is no distinction between the infinitive and present forms of verbs, with the exception of the verbs 'to be' and 'to have'. In addition, verbs do not conjugate differently depending on
1876-447: A simple face-centered cubic structure (four atoms per unit cell). When quenched to room temperature it converts to β-Mn, but it can be stabilized at room temperature by alloying it with at least 5 percent of other elements (such as C, Fe, Ni, Cu, Pd or Au), and these solute-stabilized alloys distort into a face-centered tetragonal structure. Delta manganese (δ-Mn) forms when heated above 1,406 K (1,130 °C; 2,070 °F) and
2010-513: A single negation. Certain words in Afrikaans would be contracted. For example, moet nie , which literally means 'must not', usually becomes moenie ; although one does not have to write or say it like this, virtually all Afrikaans speakers will change the two words to moenie in the same way as do not is contracted to don't in English. Manganese Manganese is a chemical element ; it has symbol Mn and atomic number 25. It

Lichtenstein Castle is a castle in Harbour Road that was modelled after the Schloss Lichtenstein in Germany. The markets are used by both tourists and locals alike and offers handmade arts and crafts as well as
2278-421: A variety of foods. Off the coast of Hout Bay, is a Big Wave known as "Dungeons". The annual Red Bull Big Wave Africa competition was held here but has been suspended. Swells of up to 47 feet (14.3 m) have been recorded here as well as numerous deaths as a result of boating, diving and surfing-related incidents in the area. The spot itself consists of various reefs. The most popular is called "2.5" since it

There is also a reef that is reputed to be able to hold a 100-foot-high (30 m) wave, should one ever come. Before the use of jet-skis to enter and leave the area, the surfers who braved these waters had to paddle through a dark and deep channel, through to where the waves break. Hout Bay is the base port to several sports fishing charter boats and offers yellowfin tuna (Thunnus Albacares), longfin tuna (Thunnus Alalunga), and yellowtail (Seriola Lalandi) fishing. A variety of pelagic sea bird species may be sighted at different times of

It evolved from the Dutch vernacular of South Holland ( Hollandic dialect ) spoken by the predominantly Dutch settlers and enslaved population of the Dutch Cape Colony , where it gradually began to develop distinguishing characteristics in the 17th and 18th centuries. Although Afrikaans has adopted words from other languages, including German and
3216-466: Is a brown pigment for paint and is a constituent of natural umber . Tetravalent manganese is used as an activator in red-emitting phosphors . While many compounds are known which show luminescence , the majority are not used in commercial application due to low efficiency or deep red emission. However, several Mn activated fluorides were reported as potential red-emitting phosphors for warm-white LEDs. But to this day, only K 2 SiF 6 :Mn
3350-552: Is a commonly used laboratory reagent because of its oxidizing properties; it is used as a topical medicine (for example, in the treatment of fish diseases). Solutions of potassium permanganate were among the first stains and fixatives to be used in the preparation of biological cells and tissues for electron microscopy. Aside from various permanganate salts, Mn(VII) is represented by the unstable, volatile derivative Mn 2 O 7 . Oxyhalides (MnO 3 F and MnO 3 Cl) are powerful oxidizing agents . The most prominent example of Mn in

It is a transition metal with a multifaceted array of industrial alloy uses, particularly in stainless steels . It improves strength, workability, and resistance to wear. Manganese oxide is used as an oxidising agent; as a rubber additive; and in glass making, fertilisers, and ceramics. Manganese sulfate can be used as
3752-512: Is absent from the other West Germanic standard languages. For example: Both French and San origins have been suggested for double negation in Afrikaans. While double negation is still found in Low Franconian dialects in West Flanders and in some "isolated" villages in the centre of the Netherlands (such as Garderen ), it takes a different form, which is not found in Afrikaans. The following
3886-549: Is also seen in the mineral rhodochrosite ( manganese(II) carbonate ). Manganese(II) commonly exists with a high spin, S = 5/2 ground state because of the high pairing energy for manganese(II). There are no spin-allowed d–d transitions in manganese(II), which explain its faint color. Manganese forms a large variety of organometallic derivatives, i.e., compounds with Mn-C bonds. The organometallic derivatives include numerous examples of Mn in its lower oxidation states, i.e. Mn(−III) up through Mn(I). This area of organometallic chemistry
4020-469: Is an example: Compare with Ek wil dit nie doen nie , which changes the meaning to 'I want not to do this'. Whereas Ek wil nie dit doen nie emphasizes a lack of desire to act, Ek wil dit nie doen nie emphasizes the act itself. The -ne was the Middle Dutch way to negate but it has been suggested that since -ne became highly non-voiced, nie or niet was needed to complement
4154-568: Is an oxidant useful in organic synthesis . Solid compounds of manganese(III) are characterized by its strong purple-red color and a preference for distorted octahedral coordination resulting from the Jahn-Teller effect . A particularly common oxidation state for manganese in aqueous solution is +2, which has a pale pink color. Many manganese(II) compounds are known, such as the aquo complexes derived from manganese(II) sulfate (MnSO 4 ) and manganese(II) chloride (MnCl 2 ). This oxidation state

Of greatest commercial interest is "MMT", methylcyclopentadienyl manganese tricarbonyl , which is used as an anti-knock compound added to gasoline (petrol) in some countries. It features Mn(I). Consistent with other aspects of Mn(II) chemistry, manganocene ( Mn(C 5 H 5 ) 2 ) is high-spin. In contrast, its neighboring metal iron forms an air-stable, low-spin derivative in
4422-483: Is composed of one stable isotope , Mn. Several radioisotopes have been isolated and described, ranging in atomic weight from 46 u ( Mn) to 72 u ( Mn). The most stable are Mn with a half-life of 3.7 million years, Mn with a half-life of 312.2 days, and Mn with a half-life of 5.591 days. All of the remaining radioactive isotopes have half-lives of less than three hours, and the majority of less than one minute. The primary decay mode in isotopes lighter than
4556-421: Is dominant in a given soil. At pH values less than 6 or under anaerobic conditions, Mn(II) dominates, while under more alkaline and aerobic conditions, Mn(III,IV) oxides and hydroxides predominate. These effects of soil acidity and aeration state on the form of Mn can be modified or controlled by microbial activity. Microbial respiration can cause both the oxidation of Mn to the oxides, and it can cause reduction of
4690-586: Is familiar in the laboratory in the form of the deep violet salt potassium permanganate . It occurs at the active sites in some enzymes . Of particular interest is the use of a Mn-O cluster , the oxygen-evolving complex , in the production of oxygen by plants. Manganese is a silvery-gray metal that resembles iron. It is hard and very brittle, difficult to fuse, but easy to oxidize. Manganese and its common ions are paramagnetic . Manganese tarnishes slowly in air and oxidizes ("rusts") like iron in water containing dissolved oxygen. Naturally occurring manganese
4824-545: Is found throughout the world's oceans, 90% of which originates from hydrothermal vents. Particulate Mn develops in buoyant plumes over an active vent source, while the dMn behaves conservatively. Mn concentrations vary between the water columns of the ocean. At the surface, dMn is elevated due to input from external sources such as rivers, dust, and shelf sediments. Coastal sediments normally have lower Mn concentrations, but can increase due to anthropogenic discharges from industries such as mining and steel manufacturing, which enter

Polyalkyl and polyaryl derivatives of manganese often exist in higher oxidation states, reflecting the electron-releasing properties of alkyl and aryl ligands. One example is [Mn(CH 3 ) 6 ] . The origin of the name manganese is complex. In ancient times, two black minerals were identified from
5226-408: Is mainly mined in South Africa, Australia, China, Gabon, Brazil, India, Kazakhstan, Ghana, Ukraine and Malaysia. For the production of ferromanganese , the manganese ore is mixed with iron ore and carbon, and then reduced either in a blast furnace or in an electric arc furnace. The resulting ferromanganese has a manganese content of 30–80%. Pure manganese used for the production of iron-free alloys
5360-555: Is neither a creole nor a direct descendant of Dutch, but a fusion of two transmission pathways. Most of the first settlers whose descendants today are the Afrikaners were from the United Provinces (now Netherlands), with up to one-sixth of the community of French Huguenot origin, and a seventh from Germany. African and Asian workers, Cape Coloured children of European settlers and Khoikhoi women, and slaves contributed to
5494-424: Is produced by leaching manganese ore with sulfuric acid and a subsequent electrowinning process. A more progressive extraction process involves directly reducing (a low grade) manganese ore by heap leaching . This is done by percolating natural gas through the bottom of the heap; the natural gas provides the heat (needs to be at least 850 °C) and the reducing agent (carbon monoxide). This reduces all of

Manganese isotopic contents are typically combined with chromium isotopic contents and have found application in isotope geology and radiometric dating . Mn–Cr isotopic ratios reinforce the evidence from Al and Pd for the early history of the Solar System . Variations in Cr/ Cr and Mn/Cr ratios from several meteorites suggest an initial Mn/ Mn ratio, which indicate that Mn–Cr isotopic composition must result from in situ decay of Mn in differentiated planetary bodies. Hence, Mn provides additional evidence for nucleosynthetic processes immediately before coalescence of

Relations between the residents of Hout Bay and those of Imizamo Yethu have been strained for several years following the national elections in 1994 and 1999. The initial response to Imizamo Yethu was not favourable, and residents of Hout Bay, represented by the Hout Bay Ratepayers' Association and the Hout Bay Residents' Association, strongly objected to
6030-442: Is stable up to the manganese melting point of 1,519 K (1,250 °C; 2,270 °F). It has a body-centered cubic structure (two atoms per cubic unit cell). Common oxidation states of manganese are +2, +3, +4, +6, and +7, although all oxidation states from −3 to +7 have been observed. Manganese in oxidation state +7 is represented by salts of the intensely purple permanganate anion MnO − 4 . Potassium permanganate
6164-405: Is unusual among elemental metals in having a very complex unit cell, with 58 atoms per cell (29 atoms per primitive unit cell) in four different types of site. It is paramagnetic at room temperature and antiferromagnetic at temperatures below 95 K (−178 °C). Beta manganese (β-Mn) forms when heated above the transition temperature of 973 K (700 °C; 1,290 °F). It has

9514-453: The Dutch established a colony in Table Bay in 1652, a great quantity of good timber was required for construction, shipbuilding and other purposes. There was no large forest in the immediate vicinity of the settlement, mainly because the rainfall was not high enough. It was soon apparent that the colonists would be able to fell wood they needed in the wetter valley that lay on the other side of
9648-571: The English boat, the "Consent" which was becalmed at the entrance to the Bay, was sent in the ship's pinnace at dusk on a chancy venture because Hout Bay was unknown wild country and the time was late afternoon which would make it difficult for him to find the Consent in the darkness. Recorded in the Rutter (Logbook) by the pilot, John Davis: "Chapman’s Chaunce hath in latitude 34-10 and is a harbour which Leith within
9782-514: The Late Stone Age people. They had no metal tools or weapons and used stone to make whatever implements they needed. They were gatherers of wild plants, shellfish and the seabirds and animals that were washed ashore. They also hunted and fished using hooks fashioned from bones and nets made from fibrous plants and the skins of animals. The Khoi-Khoi and Bushmen were descendants of the late Stone Age people. They were called Khoi-Khoi because of
9916-465: The Solar System. Four allotropes (structural forms) of solid manganese are known, labeled α, β, γ and δ, and occurring at successively higher temperatures. All are metallic, stable at standard pressure, and have a cubic crystal lattice, but they vary widely in their atomic structures. Alpha manganese (α-Mn) is the equilibrium phase at room temperature. It has a body-centered cubic lattice and
10050-564: The alloys particularly useful in harsh automotive and industrial environments. Manganese oxide and sulfate are components of fertilizers. In the year 2000, an estimated 20,000 tons of these compounds were used in fertilizers in the US alone. A comparable amount of Mn compounds was also used in animal feeds. Methylcyclopentadienyl manganese tricarbonyl is an additive in some unleaded gasoline to boost octane rating and reduce engine knocking . Manganese(IV) oxide (manganese dioxide, MnO 2 )
10184-615: The beach for processing the fish. They owned Trans Africa Fisheries. The Trautmann brothers introduced the valuable frozen rock lobster tail export business and the Dorman family, who like the Trautmanns, had originally bought land in the 19th century for farming purposes became more involved in the fishing industry. Duikersklip and Chapman's Peak Fisheries were two companies owned by the Dormans. Today Chapman's Peak fisheries have expanded to incorporate
10318-447: The challenges of demotion and emigration that it faces in South Africa, the Afrikaans vernacular remains competitive, being popular in DSTV pay channels and several internet sites, while generating high newspaper and music CD sales. A resurgence in Afrikaans popular music since the late 1990s has invigorated the language, especially among a younger generation of South Africans. A recent trend is
10452-425: The clicking sounds contained within their language. The Khoi-Khoi were also called Strandlopers because they gathered food from the beaches. Some people also referred to them as Kaapmans , Men from the Cape. The Khoikhoi were gatherers, hunters and herders, which meant that apart from gathering and hunting for food, they also possessed large herds of cattle and sheep. They lived in huts made of restio mats tied to
10586-811: The course of the 18th century. As early as the mid-18th century and as recently as the mid-20th century, Afrikaans was known in standard Dutch as a 'kitchen language' (Dutch: kombuistaal ), lacking the prestige accorded, for example, even by the educational system in Africa, to languages spoken outside Africa. Other early epithets setting apart Kaaps Hollands (' Cape Dutch ', i.e. Afrikaans) as putatively beneath official Dutch standards included geradbraakt , gebroken and onbeschaafd Hollands ('mutilated, broken, or uncivilised Dutch'), as well as verkeerd Nederlands ('incorrect Dutch'). Historical linguist Hans den Besten theorises that modern Standard Afrikaans derives from two sources: So Afrikaans, in his view,
10720-504: The development of Afrikaans. The slave population was made up of people from East Africa, West Africa, Mughal India , Madagascar , and the Dutch East Indies (modern Indonesia). A number were also indigenous Khoisan people, who were valued as interpreters, domestic servants, and labourers. Many free and enslaved women married or cohabited with the male Dutch settlers. M. F. Valkhoff argued that 75% of children born to female slaves in
10854-455: The early 20th century Afrikaans was considered a Dutch dialect , alongside Standard Dutch , which it eventually replaced as an official language. Before the Boer wars , "and indeed for some time afterwards, Afrikaans was regarded as inappropriate for educated discourse. Rather, Afrikaans was described derogatorily as 'a kitchen language' or 'a bastard jargon', suitable for communication mainly between
10988-499: The east it is bordered by the Vlakkenberg, Skoorsteenskopberg and Constantiaberg . Chapman's Peak Drive is carved out of the mountainside and leads towards Noordhoek and onwards to Cape Point . The sheltered bay of Hout Bay has a white sand beach, an attraction for tourists and locals alike. Hout Bay has one of the busiest fishing harbours in the Western Cape with an established tuna , snoek and crayfish industry. The harbour
11122-477: The element, in the form of Spiegeleisen . Manganese comprises about 1000 ppm (0.1%) of the Earth's crust and is the 12th most abundant element. Soil contains 7–9000 ppm of manganese with an average of 440 ppm. The atmosphere contains 0.01 μg/m . Manganese occurs principally as pyrolusite ( MnO 2 ), braunite (Mn Mn 6 )SiO 12 ), psilomelane (Ba,H 2 O) 2 Mn 5 O 10 , and to
11256-491: The form of ferrocene ( Fe(C 5 H 5 ) 2 ). When conducted under an atmosphere of carbon monoxide , reduction of Mn(II) salts gives dimanganese decacarbonyl Mn 2 (CO) 10 , an orange and volatile solid. The air-stability of this Mn(0) compound (and its many derivatives) reflects the powerful electron-acceptor properties of carbon monoxide. Many alkene complexes and alkyne complexes are derived from Mn 2 (CO) 10 . In Mn(CH 3 ) 2 (dmpe) 2 , Mn(II)
11390-626: The form of the Hout Bay Hotel was built sometime between 1871 and 1889 by Jacob Trautman. Originally known as the Royal Hotel it was a popular honeymoon hotel at the end of the 19th century. Chapman's Peak Hotel was originally called the Beach Hotel and was built in 1903 after the original hotel was gutted by fire. It was a noted example of an Edwardian seaside hotel until 1981 when extensive alterations were embarked upon. Flora Bay bungalows had been
11524-461: The free element when it was isolated much later. Manganese dioxide, which is abundant in nature, has long been used as a pigment. The cave paintings in Gargas that are 30,000 to 24,000 years old are made from the mineral form of MnO 2 pigments. Manganese compounds were used by Egyptian and Roman glassmakers, either to add to, or remove, color from glass. Use as "glassmakers soap" continued through
11658-473: The government for Afrikaans, in terms of education, social events, media (TV and radio), and general status throughout the country, given that it now shares its place as official language with ten other languages. Nevertheless, Afrikaans remains more prevalent in the media – radio, newspapers and television – than any of the other official languages, except English. More than 300 book titles in Afrikaans are published annually. South African census figures suggest
11792-406: The increased availability of pre-school educational CDs and DVDs. Such media also prove popular with the extensive Afrikaans-speaking emigrant communities who seek to retain language proficiency in a household context. Afrikaans-language cinema showed signs of new vigour in the early 21st century. The 2007 film Ouma se slim kind , the first full-length Afrikaans movie since Paljas in 1998,
11926-521: The informal settlement. The 18 hectares (44 acres) area supports 20,000 people, with many of these living in cramped and squalid conditions with no plumbing, roads or any discernible infrastructure for sustainable living. This is in sharp contrast to the affluence of residences in much of Hout Bay. In addition to much middle-income housing for local South Africans, there are also a number of multi-million rand mansions, luxurious holiday homes and some small wine estates. As of 2007, political differences between
12060-529: The language distance for Anglophones once remarked that the differences between (Standard) Dutch and Afrikaans are comparable to those between the Received Pronunciation and Southern American English . Afrikaans is an official language of the Republic of South Africa and a recognised national language of the Republic of Namibia. Post-apartheid South Africa has seen a loss of preferential treatment by
12194-576: The language of instruction for half the subjects taught in non-White schools (with English continuing for the other half). Although English is the mother tongue of only 8.2% of the population, it is the language most widely understood, and the second language of a majority of South Africans. Afrikaans is more widely spoken than English in the Northern and Western Cape provinces, several hundred kilometres from Soweto. The Black community's opposition to Afrikaans and preference for continuing English instruction
12328-513: The likes of big Afrikaans Hollywood film stars, like Charlize Theron ( Monster ) and Sharlto Copley ( District 9 ) promoting their mother tongue. SABC 3 announced early in 2009 that it would increase Afrikaans programming due to the "growing Afrikaans-language market and [their] need for working capital as Afrikaans advertising is the only advertising that sells in the current South African television market". In April 2009, SABC3 started screening several Afrikaans-language programmes. There
12462-632: The location and management of the informal settlement and also the suggestion of an increase in the land used for the settlement in 2001. Both associations feared that the land invasions at the time were racially motivated, whereas the African National Congress feared that the Residents Association of Hout Bay was creating a racially charged environment and refusing to develop land for housing. Current issues between residents of Hout Bay and Imizamo Yethu are focused on service delivery for
12596-530: The majority are of Afrikaans-speaking Afrikaner and Coloured South-African descent. A much smaller and unknown number of speakers also reside in the Dutch Caribbean . Contrary to popular belief, the majority of Afrikaans speakers today are not Afrikaners or Boers , but Coloureds . In 1976, secondary-school pupils in Soweto began a rebellion in response to the government's decision that Afrikaans be used as
12730-412: The manganese content reaches 4%, the embrittlement of the steel becomes a dominant feature. The embrittlement decreases at higher manganese concentrations and reaches an acceptable level at 8%. Steel containing 8 to 15% of manganese has a high tensile strength of up to 863 MPa. Steel with 12% manganese was discovered in 1882 by Robert Hadfield and is still known as Hadfield steel (mangalloy) . It
12864-503: The manganese ore to manganese oxide (MnO), which is a leachable form. The ore then travels through a grinding circuit to reduce the particle size of the ore to between 150 and 250 μm, increasing the surface area to aid leaching. The ore is then added to a leach tank of sulfuric acid and ferrous iron (Fe ) in a 1.6:1 ratio. The iron reacts with the manganese dioxide (MnO 2 ) to form iron hydroxide (FeO(OH)) and elemental manganese (Mn). This process yields approximately 92% recovery of
12998-457: The manganese. For further purification, the manganese can then be sent to an electrowinning facility. In 1972, the CIA 's Project Azorian , through billionaire Howard Hughes , commissioned the ship Hughes Glomar Explorer with the cover story of harvesting manganese nodules from the sea floor. That triggered a rush of activity to collect manganese nodules, which was not actually practical until
13132-619: The metal, but that is uncertain. By the mid-18th century, the Swedish chemist Carl Wilhelm Scheele used manganese dioxide to produce chlorine . First, hydrochloric acid , or a mixture of dilute sulfuric acid and sodium chloride was made to react with manganese dioxide, and later hydrochloric acid from the Leblanc process was used and the manganese dioxide was recycled by the Weldon process . The production of chlorine and hypochlorite bleaching agents
13266-569: The metals and organic compounds can then cause them to be oxidized while the Mn(III,IV) oxides are reduced to Mn (e.g., Cr to Cr(VI) and colorless hydroquinone to tea-colored quinone polymers). Manganese is essential to iron and steel production by virtue of its sulfur -fixing, deoxidizing , and alloying properties. Manganese has no satisfactory substitute in these applications in metallurgy. Steelmaking , including its ironmaking component, has accounted for most manganese demand, presently in
13400-418: The most abundant stable isotope, Mn, is electron capture and the primary mode in heavier isotopes is beta decay . Manganese also has three meta states . Manganese is part of the iron group of elements, which are thought to be synthesized in large stars shortly before the supernova explosion. Mn decays to Cr with a half-life of 3.7 million years. Because of its relatively short half-life, Mn
13534-524: The ocean from river inputs. Surface dMn concentrations can also be elevated biologically through photosynthesis and physically from coastal upwelling and wind-driven surface currents. Internal cycling such as photo-reduction from UV radiation can also elevate levels by speeding up the dissolution of Mn-oxides and oxidative scavenging, preventing Mn from sinking to deeper waters. Elevated levels at mid-depths can occur near mid-ocean ridges and hydrothermal vents. The hydrothermal vents release dMn enriched fluid into
13668-514: The other official languages. In 1996, for example, the South African Broadcasting Corporation reduced the amount of television airtime in Afrikaans, while South African Airways dropped its Afrikaans name Suid-Afrikaanse Lugdiens from its livery . Similarly, South Africa's diplomatic missions overseas now display the name of the country only in English and their host country's language, and not in Afrikaans. Meanwhile,
13802-410: The other way round. Mutual intelligibility thus tends to be asymmetrical, as it is easier for Dutch speakers to understand Afrikaans than for Afrikaans speakers to understand Dutch. In general, mutual intelligibility between Dutch and Afrikaans is far better than between Dutch and Frisian or between Danish and Swedish . The South African poet writer Breyten Breytenbach , attempting to visualise
13936-553: The owner Mr. Lucien Plessis. In 1922 Chapman's Peak Drive was opened to the public. It had been built by the provincial administration using convict labour. It had taken 7 years to build and had cost (R40 000). German immigrant and farmer Jacob Trautmann established the first fishing village here in 1867. The fishing industry expanded substantially in the 1930s when fish became a popular item on menus and improved facilities for transporting fish inland were created. The Trautmann family improved their fishing boats and built more sheds on
14070-441: The oxides to the divalent cation. The Mn(III,IV) oxides exist as brownish-black stains and small nodules on sand, silt, and clay particles. These surface coatings on other soil particles have high surface area and carry negative charge. The charged sites can adsorb and retain various cations, especially heavy metals (e.g., Cr , Cu , Zn , and Pb ). In addition, the oxides can adsorb organic acids and other compounds. The adsorption of
14204-411: The past tense is also often replaced with the perfect.) When telling a longer story, Afrikaans speakers usually avoid the perfect and simply use the present tense, or historical present tense instead (as is possible, but less common, in English as well). A particular feature of Afrikaans is its use of the double negative ; it is classified in Afrikaans as ontkennende vorm and is something that
14338-1056: The pollution. The group provided a platform for residents to voice concerns and questions and communicated with all parties involved, including the Oceana group , the City of Cape Town's environmental department, representatives of the fishing community and the relevant worker's unions. The factory officially closed in 2020. Hout Bay is divided into several neighbourhoods. The Hout Bay Neighbourhood Watch describes 28 distinct areas. Neighbourhoods include Scott Estate, Hanging Meadows, Baviaanskloof, Hillcrest, Bergendal, Penzance, Imizamo Yethu , Meadows, Tarragona, Oakwood, Bokkemanskloof, Overkloof, Silvermist, Longkloof, Valley, Victorskloof, Nooitgedacht, Beach Estate, Northshore, Mount Rhodes, Klein Leeukoppie Estate, Ruyteplaats, Tierboskloof, Kronenzicht, Hangberg , Hout Bay Heights and Hughenden Estate. Llandudno an entirely separate village of about 200 houses lies over
14472-571: The process has seen widespread use ever since. The invention of the Leclanché cell in 1866 and the subsequent improvement of batteries containing manganese dioxide as cathodic depolarizer increased the demand for manganese dioxide. Until the development of batteries with nickel–cadmium and lithium, most batteries contained manganese. The zinc–carbon battery and the alkaline battery normally use industrially produced manganese dioxide because naturally occurring manganese dioxide contains impurities. In
14606-400: The range of 85% to 90% of the total demand. Manganese is a key component of low-cost stainless steel . Often ferromanganese (usually about 80% manganese) is the intermediate in modern processes. Small amounts of manganese improve the workability of steel at high temperatures by forming a high-melting sulfide and preventing the formation of a liquid iron sulfide at the grain boundaries. If
14740-476: The regions of the Magnetes (either Magnesia , located within modern Greece, or Magnesia ad Sipylum , located within modern Turkey). They were both called magnes from their place of origin, but were considered to differ in sex. The male magnes attracted iron, and was the iron ore now known as lodestone or magnetite , and which probably gave us the term magnet . The female magnes ore did not attract iron, but
14874-459: The ruins of the manganese ore jetty and the old mine workings up the mountain. In 1880, Crisp Arnold set up fishing sheds and started curing snoek for export to Mauritius . In 1895 Walter Gurney built the first church in Hout Bay. It still stands today and is known as St Peter's the Fisherman. The first school in Hout Bay was started in this church. In 1904 Hout Bay's first crawfish canning factory
15008-400: The safety of travellers using the route. The East and West forts built by the Dutch in the 18th century can also be visited, with the original cannons and barracks still standing on the slopes of Chapman's Peak. The East Fort is the oldest operating gun battery in the world. The mountains surrounding Hout Bay also have hiking trails. In the same area is a bronze statue of a leopard on a rock at
15142-415: The same basic reaction, but a different electrolyte mixture. In 2002, more than 230,000 tons of manganese dioxide was used for this purpose. Copper alloys of manganese, such as Manganin , are commonly found in metal element shunt resistors used for measuring relatively large amounts of current. These alloys have very low temperature coefficient of resistance and are resistant to sulfur. This makes
15276-494: The south-west point under a little hill like charring cross (a sculptured memorial of a cross on an ornamental mounting in London) close hanging by the seaside of the S.S.W side of the land " Chapmans Chaunce was the first name given to Hout Bay and it was also the first English name to appear on the maps of Southern Africa . In 1614 an English sailor records having taken wood from the forest of Hout Bay in order to mend his ship. When
15410-442: The subject. For example, Only a handful of Afrikaans verbs have a preterite , namely the auxiliary wees ('to be'), the modal verbs , and the verb dink ('to think'). The preterite of mag ('may') is rare in contemporary Afrikaans. All other verbs use the perfect tense, het + past participle (ge-), for the past. Therefore, there is no distinction in Afrikaans between I drank and I have drunk . (In colloquial German,
15544-537: The two languages. Afrikaans has a considerably more regular morphology, grammar, and spelling. There is a high degree of mutual intelligibility between the two languages, particularly in written form. Afrikaans acquired some lexical and syntactical borrowings from other languages such as Malay , Khoisan languages , Portuguese, and Bantu languages , and Afrikaans has also been significantly influenced by South African English . Dutch speakers are confronted with fewer non-cognates when listening to Afrikaans than
15678-717: The victims. Hout Bay is surrounded by mountains to the north, east and west and the southern Atlantic Ocean to the south. In the north, it is bordered by Table Mountain National Park comprising the Orangekloof Nature reserve and the bottom slopes of Table Mountain beyond that. To the north-west, it is bordered by the backside of the Twelve Apostles, known as the Oranjekloof. To the west, it is bordered by Little Lion's Head, Karbonkelberg , Kaptein's Peak and The Sentinel . To
15812-413: The water's edge, looking out over the ocean. In the 1980s and 1990s, Hout Bay promoted itself as The Republic of Hout Bay , as a tourism gimmick, which included printing fake "passports". The Red Bull Big Wave Africa surfing contest was held at the infamous surf spot known locally as Dungeons, about 1 kilometre offshore off Duiker Island. This contest no longer takes place. Some of the biggest waves in
15946-589: The water. The dMn can then travel up to 4,000 km due to the microbial capsules present, preventing exchange with particles, lowing the sinking rates. Dissolved Mn concentrations are even higher when oxygen levels are low. Overall, dMn concentrations are normally higher in coastal regions and decrease when moving offshore. Manganese occurs in soils in three oxidation states: the divalent cation, Mn and as brownish-black oxides and hydroxides containing Mn (III,IV), such as MnOOH and MnO 2 . Soil pH and oxidation-reduction conditions affect which of these three forms of Mn
16080-465: The world are found here and these attract surfers from all over the world during the winter months (June - August). Local boat operators provide the opportunity to watch and take photographs of the surfers. The Hout Bay Yacht Club is situated in the working harbour and provides moorings for both recreational, fishing and sailing boats. Hout Bay has several attractions, and receives a high number of visitors, especially on weekends and during peak season in
16214-740: The year. The harbour slipway is used for boat access to the recreational dive sites of much of the west coast of the Cape Peninsula. These include a number of reef and wreck scuba diving sites, and the snorkeling site at Duiker Island for watching Cape fur seals. Wreck sites include the SS Maori, the Bos400, MFV Aster, and MFV Katsu Maru. Reef dives include Tafelberg Reef, Vulcan Rock and Star Wall. Afrikaans language Afrikaans ( / ˌ æ f r ɪ ˈ k ɑː n s / AF -rih- KAHNSS , / ˌ ɑː f -, - ˈ k ɑː n z / AHF -, - KAHNZ )
16348-457: The years and had a negative impact not only on tourism, but on the lives of the people living in the whole area. In 2014, photographer and writer Kiara Worth and Hout Bay based singer Ike Moriz created the air pollution portfolio of the HBRRA ( Hout Bay Rate Payers and Residents Association ). Worth and Moriz founded the environmental group Fresh Air for Hout Bay to research the causes and effects of
16482-478: Was a large consumer of manganese ores. Scheele and others were aware that pyrolusite (mineral form of manganese dioxide) contained a new element. Johan Gottlieb Gahn isolated an impure sample of manganese metal in 1774, which he did by reducing the dioxide with carbon . The manganese content of some iron ores used in Greece led to speculations that steel produced from that ore contains additional manganese, making
16616-574: Was erected on the 100th anniversary of the founding of the Society of Real Afrikaners , and the 50th anniversary of Afrikaans being declared an official language of South Africa in distinction to Dutch. The earliest Afrikaans texts were some doggerel verse from 1795 and a dialogue transcribed by a Dutch traveller in 1825. Afrikaans used the Latin alphabet around this time, although the Cape Muslim community used
16750-409: Was established in the wreck of an old sailing ship, The R Morrow that stood where the present South African Sea Products factory is today. For almost 10 years the factory operated successfully exporting canned crawfish overseas and providing work for the local inhabitants. On 31 July 1914 a leak in the acetylene gas supply caused an explosion which blew up the canning factory, killing 7 people including
16884-559: Was influenced by Eugene Nida 's theory of dynamic equivalence which focused on finding the nearest equivalent in the receptor language to the idea that the Greek, Hebrew or Aramaic wanted to convey. A new translation, Die Bybel: 'n Direkte Vertaling was released in November 2020. It is the first truly ecumenical translation of the Bible in Afrikaans as translators from various churches, including
17018-429: Was originally made up of two farms, which were slowly subdivided to make way for urban expansion. While still maintaining its rural atmosphere, the area of Hout Bay has more than 5,960 residences inhabited by a population of at least 17,900 people (as of 2011). The pronunciation of "Hout Bay" varies: From remains found in a cave, we know that people lived in this cave between 100 AD and 500 AD. These people were known as
17152-399: Was previously referred to as 'Cape Dutch' ( Kaap-Hollands or Kaap-Nederlands ), a term also used to refer to the early Cape settlers collectively, or the derogatory 'kitchen Dutch' ( kombuistaal ) from its use by slaves of colonial settlers "in the kitchen". The Afrikaans language arose in the Dutch Cape Colony , through a gradual divergence from European Dutch dialects , during
17286-649: Was the translation of the whole Bible into Afrikaans. While significant advances had been made in the textual criticism of the Bible, especially the Greek New Testament , the 1933 translation followed the Textus Receptus and was closely akin to the Statenbijbel . Before this, most Cape Dutch-Afrikaans speakers had to rely on the Dutch Statenbijbel . This Statenvertaling had its origins with
17420-531: Was under development As of 2018. The official orthography of Afrikaans is the Afrikaanse Woordelys en Spelreëls , compiled by Die Taalkommissie . The Afrikaners primarily were Protestants, of the Dutch Reformed Church of the 17th century. Their religious practices were later influenced in South Africa by British ministries during the 1800s. A landmark in the development of the language
17554-622: Was underlined when the government rescinded the policy one month after the uprising: 96% of Black schools chose English (over Afrikaans or native languages) as the language of instruction. Afrikaans-medium schools were also accused of using language policy to deter Black African parents. Some of these parents, in part supported by provincial departments of education, initiated litigation which enabled enrolment with English as language of instruction. By 2006 there were 300 single-medium Afrikaans schools, compared to 2,500 in 1994, after most converted to dual-medium education. Due to Afrikaans being viewed as
17688-572: Was used for British military steel helmets and later by the U.S. military. Manganese is used in production of alloys with aluminium. Aluminium with roughly 1.5% manganese has increased resistance to corrosion through grains that absorb impurities which would lead to galvanic corrosion . The corrosion-resistant aluminium alloys 3004 and 3104 (0.8 to 1.5% manganese) are used for most beverage cans . Before 2000, more than 1.6 million tonnes of those alloys were used; at 1% manganese, this consumed 16,000 tonnes of manganese. Manganese(IV) oxide
17822-414: Was used in the original type of dry cell battery as an electron acceptor from zinc, and is the blackish material in carbon–zinc type flashlight cells. The manganese dioxide is reduced to the manganese oxide-hydroxide MnO(OH) during discharging, preventing the formation of hydrogen at the anode of the battery. The same material also functions in newer alkaline batteries (usually battery cells), which use
17956-438: Was used to decolorize glass. This female magnes was later called magnesia , known now in modern times as pyrolusite or manganese dioxide . Neither this mineral nor elemental manganese is magnetic. In the 16th century, manganese dioxide was called manganesum (note the two Ns instead of one) by glassmakers, possibly as a corruption and concatenation of two words, since alchemists and glassmakers eventually had to differentiate
