We propose a new concept which allows us to apply any numerical method of weak approximation to a very broad class of stochastic differential equations (SDEs) with nonglobally Lipschitz coefficients. Following this concept, we discard the approximate trajectories which leave a sufficiently large sphere. We prove that accuracy of any method of weak order p is estimated by ε + O(hp), where ε can ...

INTRODUCTION Traumatic brain Injuries represents a significant cause of morbidity and mortality worldwide and road traffic crashes accounts for a significant proportion of these injuries. However, access to neurosurgical care is poor in low income countries like Tanzania. The aim of this study was to assess the management and outcome of Traumatic brain injury patients at a tertiary level health...

The threat of global warming has prompted numerous recent studies on the thermal tolerance of marine species. A widely used method to determine the upper thermal limit has been the Critical Thermal Maximum (CTMax), a dynamic method, meaning that temperature is increased gradually until a critical point is reached. This method presents several advantages over static methods, however, there is on...

Marine invertebrates possess a variety of interesting functions and some of them have been well studied from the standpoint of biotechnology. Shrimp and shellfish are useful animals among marine invertebrates. In this section, we describe the recent advances in biological defense system of shrimp and the biomineralization system of shellfish as examples of which molecular mechanisms have been w...

An 8-week feeding trial was conducted to evaluate effects of dietary organic zinc (zinc amino acid chelate) on growth performance, mineral bioaccumulation in whole body, hepatopancreas and carapace, innate immune response antioxidant capacity juvenile Pacific white shrimp Litopenaeus vannamei. Five isonitrogenous isolipidic diets were formulated contain different levels 46.4 (basal diet), 65.5,...
