A Preliminary Study on Rainfall Interception Loss and Water Yield Analysis on Arabica Coffee Plants in Central Aceh Regency, Indonesia
B.C. Alfiansyah Yulianur,Maimun Rizalihadi,Reza Benara
Aceh International Journal of Science and Technology , 2012,
Abstract: Rainfall interception loss from plants or trees can reduce a net rainfall as source of water yield. The amount of rainfall interception loss depends on kinds of plants and hydro-meteorological characteristics. Therefore, it is important to study rainfall interception loss such as from Arabica Coffee plantation which is as main agricultural commodity for Central Aceh Regency. In this study, rainfall interception loss from Arabica Coffee plants was studied in Kebet Village of Central Aceh Regency, Indonesia from January 20 to March 9, 2011. Arabica coffee plants used in this study was 15 years old, height of 1.5 m and canopy of 4.567 m2. Rainfall interception loss was determined based on water balance approach of daily rainfall, throughfall, and stemflow data. Empirical regression equation between rainfall interception loss and rainfall were adopted as a model to estimate rainfall interception loss from Arabica Coffee plantation, which the coefficient of correlation, r is 0.98. In water yield analysis, this formula was applied and founded that Arabica Coffee plants intercept 76% of annual rainfall or it leaved over annual net rainfall 24% of annual rainfall. Using this net rainfall, water yield produced from Paya Bener River which is the catchment area covered by Arabica Coffee plantation was analyzed in a planning of water supply project for water needs domestic of 3 sub-districts in Central Aceh Regency. Based on increasing population until year of 2025, the results showed that the water yield will be not enough from year of 2015. However, if the catchment area is covered by forest, the water yield is still enough until year of 2025
λ-ALN: aut?matos lineares n?o-determinísticos com λ-transi??es
Bedregal, B.C.;
TEMA (S?o Carlos) , 2011, DOI: 10.5540/tema.2011.012.03.0171
Abstract: in this paper we introduce the class of linear non-deterministic automata with λ-transitions, and based on a new normal form for linear grammars, we prove that the class of languages accepted by such automata is exactly the class of linear languages. also we show that, analogously to finite automata and pushdown automata, the ocorrences of λ-transitions in a non-deterministic linear automaton not means that not be possible define a non-deterministic linear automata without λ-transitions which accept the same language. thus, λ-transitions not increases the acceptance power of this class of automata and therefore can be dispensed. finally, we present an application of this automata in the context of bioinformatics.
On approximate solutions of a certain hyperbolic partial differential equation
B.C. Pachpatte
Tamkang Journal of Mathematics , 2011, DOI: 10.5556/j.tkjm.42.2011.95-104
Abstract: In this paper we study approximatesolutions of a certain hyperbolic partial differential equation withthe given initial boundary conditions. A variant of a certainfundamental integral inequality with explicit estimate is used toestablish the results. The discrete analogues of the main resultsare also given.

H.J.J. Bingle en die stryd om Christelike opvoeding en onderwys
B.C. Schutte
Koers : Bulletin for Christian Scholarship , 1978, DOI: 10.4102/koers.v43i2.1150
Abstract: Dis vir my nie maklik om oor prof. dr. H.J.J. Bingle te skrywe nie omdat dit so moeilik gaan om afstand te verkry: ons was lewenslank te na aan mekaar. Hierdie verband strek van ons kinderdae af, daar in 1921 se koers, in die legendariese Karoodorpie, Venterstad. Toe ons paaie teen die einde van 1923 uiteengegaan het met die vaderlose gesin se vertrek na Steynsburg, was daar die hereniging in 1928 toe ons albei studente aan die PUK was, hy in die geesteswetenskappe en ek in die natuurwetenskappe. In 1931 het ons toe weer saam aan die voete van ons leermeester, J. Chris Coetzee, gesit. Daar het ons opvoedkundige vorming gestalte begin aanneem en dit het tot by sy aftrede in 1977 geduur en is sekerlik nooit afgesluit nie.
Abstraksie en veralgemening in die Wiskunde
B.C. Strydom
Koers : Bulletin for Christian Scholarship , 1967, DOI: 10.4102/koers.v35i2.1376
Abstract: Wanneer ek tot u spreek oor abstraksie en veralgemening in die Wiskunde, wil ek u aandag vestig op die belangrikheid daarvaan vir die Wiskunde, maar u terselfdertyd daarop wys dat die wiskundige hom nie langs hierdie weg heeltemal van die werklikheid kan losmaak nie.
Die antwoord van die Calvinistiese filosofie en praktyk van die opvoeding op die wysgerigreligieuse eise van die moderne tyd
B.C. Schutte
Koers : Bulletin for Christian Scholarship , 1969, DOI: 10.4102/koers.v37i1.1285
Abstract: Ons lewe in woelige, wonderlike tye. Beskrywing hiervan is aan die orde van die dag, elkeen met ander klem en treffende byvoeglike naamwoorde. Dit het mode geword om ons probleme en sogenaamde krisisse terug te voer tot die besondersheid van ons moderne eeu. Die opvoedkundige terrein is hiervan ook ’n getroue verteenwoordiger. Nuwe en besonderse tye verg nuwe en besonderse opvoedkundige benadering. Ons huise lyk en is anders, ons ouers eis en gee anders, ons gemeenskap tree anders op en is baie meer gekompliseerd, ons kinders mag psigies nog na die van ons voorgeslagte lyk en aard, maar tog is die verhoudings so totaal verskillend dat hulle maklik soos vreemde wesens vergelyk.

Abstract: Funding needs of businesses are varied, from long-term needs and a high, as is the case of material fixed assets to the lack of short duration, whose level varies frequently during the year depending on the internal and external factors, the case of circulating assets. Finance, meaning financial coverage of these needs is, of course, taking into account the permanent or temporary necessities. Long-term financing needs of businesses involve funds, whether permanent or for periods of time, operation can be done in different forms, depending on the conditions of the enterprise and financial market. Ways of long-term financing are closely linked with the ways of investment, forming together with them the financial undertaking, and management in the long term.

Abstract: A company in a difficult financial situation may procure funds and money by increasing capital, bank loans or obligations loans. The option for either of these alternatives is done taking into account several parameters: the possibility of access to such funding, and the need to use resources such acquired business objectives, level of interest, guarantees required etc.. Thus, for a prosperous society that wants to expand its business will be more advantageous to increase their capital through subscription of new shares, although it could use to issue bonds. In these circumstances, the credibility will increase if you choose to increase capital.
