Water use by a warm-temperate deciduous forest under the influence of the Asian monsoon: contributions of the overstory and understory to forest water use
(Elsevier, 2013)The warm temperate deciduous forests in Asia have a relatively dense understory, hence, it is imperative that we understand the dynamics of transpiration in both the overstory (E O) and understory (E U) of forest stands ... -
Changes in forest soil properties in different successional stages in lower tropical China
(Plosone.org, 2013)Background: Natural forest succession often affects soil physical and chemical properties. Selected physical and chemical soil properties were studied in an old-growth forest across a forest successional series in Dinghushan ... -
Derivation and solution of the heat equation in 1-D
(International Journal of Engineering, Science and Mathematics, 2013)Heat flows in the direction of decreasing temperature, that is, from hot to cool. In this paper we derive the heat equation and consider the flow of heat along a metal rod. The rod allows us to consider the temperature, ... -
Mathematical modelling of HIV infection
(IJMA, 2013)We formulate a deterministic mathematical model for the HIV/AIDS. -
Teachers` gender and primary school pupils` achievement in mathematics in Kenya
(Journal of Education and Practice, 2013)This descriptive causal comparative study examined the relationship between teacher’s gender and in primary schools pupils’ performance in mathematics in Kenya. The study objective was to investigate the effect of teachers’ ... -
Modeling co-infection of paediatric Malaria and Pneumonia
(Int. Journal of Math. Analysis, 2013)Malaria and persistent childhood diseases are a major threat to child survival in the developing world. In this paper, we develop and analyse a mathematical model for paediatric malaria and pneumonia co-infection. We ... -
Symmetry group approach to the solution of generalized burgers equation: Ut + UUx = λUxx
(2013)Symmetry of a system of differential equations is a transformation that maps any solution to another solution of the system. In Lie’s framework such transformations are groups that depend on continuous parameters and ... -
Comparison of the ratio estimate to the local linear polynomial estimate of finite population totals
(IJESM, 2013-03)In this paper, attempt to study effects of extreme observations on two estimators of finite population total theoretically and by simulation is made. We compare the ratio estimate with the local linear polynomial estimate ... -
Malaria Transmission after Artemether-Lumefantrine and Dihydroartemisinin-Piperaquine: A Randomized Trial
(The Journal of Infectious Diseases, 2013-03-06)Artemisinin-based combination therapy (ACT) reduces the potential for malaria transmission compared with non-ACTs. It is unclear whether this effect differs between ACTs. Methods. A total of 298 children (age, 6 months ... -
Functional convergence in water use of trees from different geographical regions: a meta-analysis
(Springer-Verlag Berlin Heidelberg, 2013-06)Functional convergence in water use of trees across species from diverse geographic locations was examined using data on tree water use parameters, with the intention of gaining an understanding on the capacity for water ... -
Finite element approach to the solution of fourth order beam equation
(IJESM, 2013-06)Finite element method is a class of mathematical tool which approximates solutions to initial and boundary value problems. Finite element, basic functions, stiffness matrices, systems of ordinary differential equations and ... -
Effects of outliers on estimation of finite population totals
(2013-06)In this paper, attempt to study effects of outliers on two estimators of finite population total theoretically and by simulation is made. We compare the ratio estimate with the local linear polynomial estimate of finite ... -
Forensic estimation of time of death: A mathematical model
(International Journal of Management, IT and Engineering, 2013-07)In this paper we establish the exact time of death of a murdered person. This leads to an ordinary differential equation whose solution has been analyzed to provide the approximate time of death. Forensic expert will try ... -
Residual Plasmodium falciparum Parasitemia in Kenyan Children After Artemisinin- Combination Therapy Is Associated With Increased Transmission to Mosquitoes and Parasite Recurrence
(The Journal of Infectious Diseases, 2013-08-14)Parasite clearance time after artemisinin-based combination therapy (ACT) may be increasing in Asian and African settings. The association between parasite clearance following ACT and transmissibility is currently unknown. ... -
Treatment of tea industry wastewater using a combined adsorption and advanced oxidation process
(International Conference on Sustainable Research and Innovation, 2014)Tea, produced from the evergreen plant, Camellia Sinensis, is the most widely consumed beverage in the world after water. Although tea processing has now diversified into various speciality end products such as instant, ... -
Stand characteristics and water use at two elevations in a sub-tropical evergreen forest in southern China
(Elsevier, 2014)The humid evergreen monsoon forests in China and other parts of Asia contribute significantly to the global and regional atmospheric circulation and hydrological cycle. The forests are, however, changing in structure due ... -
Seasonal dynamics in carbon dioxide fluxes of the herbaceous layer of a moist Kenyan savannah
(APPLIED ECOLOGY AND ENVIRONMENTAL RESEARCH, 2014)Strong seasonal variability in African carbon source/sink relationship is considered the continent’s most significant contribution to the global carbon cycle. Alternating dry and wet periods dictate ecosystem carbon exchange ... -
Wilson-Theta Algorithm Approach to solution of Dynamic Vibration Equations
(ResearchGate, 2014)In this paper, we examine conservative autonomous dynamic vibration equation, x¨ = − tanh2 x, which is time vibration of the displacement of a structure due to the internal forces, with no damping or external forcing. ... -
