This paper reports the result of a study that empirically determined the willingness to pay for organic vegetables among households in Anambra State, South East Nigeria. Multi-stage sampling technique was adopted in the selection of 120 respondents for the study. Primary and a secondary data collected through the aid of a well-structured questionnaire augmented with an interview schedule and a ...

Wind erosion is considered a major global environmental problem. Dust storms from the migration of sand dunes can seriously damage civil, industrial, and agricultural areas and a method to stabilize these sand dunes is mulching. The present study investigates the feasibility of using organic wastes of Press mud and Dunder with clay for the production of environmentally-friendly mulches. Sandy s...

We have introduced a selective synthesis of tertiary amines using alkyl halide and ammonium salts as the amine sources in water. This green process has outstanding superiorities, such as being eco-friendly, possessing ammonium salts, and using water as a green solvent in the absence of organic ligands or catalysts. It is worth mentioning that the presence of t-Butyl alcohol and potassi...

Stochastic process algebras have been proposed as compositional specification formalisms for performance models. In this paper, we describe a tool which aims at realising all beneficial aspects of compositional performance modelling, the TIPPtool. It incorporates methods for compositional specification as well as solution, based on state-of-the-art techniques, and wrapped in a user-friendly gra...

Climate change is strongly linked to human behavior and technologies, and many of the barriers to sustainable behavior are rather psychological than technological. More sustainable technologies and food products have been introduced to combat climate change, most often labeled with morally loaded labels such as “organic” or “environmentally friendly”. The purpose of this thesis was, first, to g...

Oxalic acid dihydrate as a green, mild and efficient catalyst for the one-pot three-component Biginelli synthesis of 3,4-dihydropyrimidin-2-(1H)-one derivatives from the reaction between β-keto esters (methyl or ethyl acetoacetate), aromatic aldehyde (benzaldehye derivatives) and urea or thiourea under thermal and solvent-free conditions with excellent yields and short reaction time is st...

background: hospital incident command system (hics) has been established with the mission of prevention, response, and recovery in hazards. regarding the key role of hospitals in medical management of events, the present study is aimed at investigating benefits, barriers, and limitations of applying hics in hospital. materials and methods: employing a review study, articles related to the afore...

This paper presents large-sample evidence that firms consider labor unemployment risk when setting their resource adjustment policies. Prior studies find that costs rise more in response to sales increases than they fall in response to sales decreases. Anderson, Banker, and Janakiraman (2003) term this phenomenon “cost stickiness” and attribute it to managers’ deliberate adjustment to committed...

Sulfonamides incorporating 1,3,5-triazine moieties can selectively and potently inhibit carbonic anhydrase transmembrane isoforms IX, XII, and XIV over cytosolic isoforms I and II. In the present work, a highly effective synthetic procedure was proposed for this group of potent cancerostatic drugs and compared with previously used methods. The synthesis of triazinyl-substituted benzene-sulfonam...
