Quantifying changes in blood chemistry in elasmobranchs can provide insights into the physiological insults caused by anthropogenic stress, and can ultimately inform conservation and management strategies. Current methods for analysing elasmobranch blood chemistry in the field are often costly and logistically challenging. We compared blood pH values measured using a portable, waterproof pH met...

T paper develops algorithms for finding Coxian generators to phase-type (PH)-majorize a PH-generator T with only real eigenvalues. In the first part of this paper, we investigate matrices S and P satisfying TP = PS and Pe= e. Conditions on T are identified for S to be an ordered Coxian generator and for P to be nonnegative, which consequently implies that S PH-majorizes T . It is shown that eve...

Present study was performed to investigate the variables that influence the removal efficiency of malachite green (aniline) dye from aqueous solution by an electrochemical (EC) technique. The batch EC studies were performed using iron electrode to evaluate the effect of operating parameters such as pHo and processes parameters such as current density and initial dye concentration. Parameters pH...

a4 + 1 a5 + .. . will see that a less wasteful notation, say [ a0 , a1 , a2 , . . . ] , is needed to represent it. Anyone attempting to compute the truncations [ a0 , a1 , . . . , ah ] = ph/qh will be delighted to notice that the definition [ a0 , a1 , . . . , ah ] = a0 + 1/[ a1 , . . . , ah ] immediately implies by induction on h that there is a correspondence ( a0 1 1 0 ) ( a1 1 1 0 ) · · · (...

Twitter is currently one of the primary venues for online information dissemination. Although its detractors portray it as nothing more than an exercise in narcissism and banality, Twitter is also used to share news stories and other information that may be of interest to a person’s followers. The current study sampled tweeters who had tweeted at least one link to an article in one of four lead...

The proper management of solid waste is the need of the time. The solid waste consists of various components, some of them are biodegradable where as other are non biodegradable. The waste from various biodegradable sources could be utilized as a feed material for the gas production. The objective of this study is food waste management through biogas production. Various parameters were studied ...

The construction and characterization of a flow-through polarographic detector for catalyzing the electroreduction of N-nitrosodiethanolamine (NDELA), is discussed. The flow-through cell is equipped with a gold wire electrode (a thin mercury film deposited on a gold substance). The response is evaluated with respect to substance diameter, length, concentration of modifying film, operating poten...
