citrus fruits contain numerous nutrients and secondary metabolites including sugars, vitamin c, flavonoids and phenols which have high antioxidant activity and nutritional value. factors such as cultivar, type of stock and fruit position affect the amount of these compounds. hence in this study the amount of sucrose, glucose, total sugar, vitamin c, flavonoids and phenols in pulp, mesocarp and ...

In an environment marked by growing claims regarding corporate social responsibility (CSR), debates on governance show the need for taking into account all the legitimate involved parties of the company within the framework of the legal or voluntary financial communication (Dowling and Pfeffer, 1975; Lind B lom, 1994; Gray et al.., 1995). If the accounting regulation, the laws and the rules in ...

[1] Because of its relevance for the global climate the Atlantic meridional overturning circulation (AMOC) has been a major research focus for many years. Yet the question of which physical mechanisms ultimately drive the AMOC, in the sense of providing its energy supply, remains a matter of controversy. Here we review both observational data and model results concerning the two main candidates...

The purpose of this paper is the investigation of strong converse results for Bernstein-Durrmeyer operators and their quasi-interpolants. For lower dimensions we improve known results by Knoop and Zhou [16] and Chen, Ditzian and Ivanov [5] in regard to the constants in their estimates and prove a strong converse theorem of type B for the quasi-interpolants introduced by Berdysheva, Jetter and S...

Recent discoveries have reopened the idea that, in the past, Mars had a period of wetness where conditions were similar to those on Earth [1]. If this was the case then it is feasible that these environments may have harboured life. The martian surface today is dry, cold and heavily bombarded by UV radiation, making it an environment unsuitable for any known terrestrial life [2]; the martian su...

Introduction: Reports of methane in the Martian atmosphere have spurred speculation about sources for that methane [1-3]. Discussion has centered on cometary/ meteoritic delivery, magmatic/mantle processes, UVbreakdown of organics, serpentinization of basalts, and generation of methane by living organisms. This paper describes an additional possibility: that buried organic remains from past lif...

در این تحقیق ساخت الکترود کربن شیشه ای اصلاح شده با فیلم گرافن اکسید و استفاده از آن در اندازه گیری اکسیداسیون الکتروشیمیایی دوپامین با استفاده از ولتامتری موج مربعی، گزارش شده است. پس از پیش تغلیظ دوپامین بر روی الکترود اصلاح شده بافیلم گرافن اکسید در پتانسیل جذب صفر ولت و در مدت زمان 140 ثانیه، روبش پتانسیل به روش موج مربعی از 2/0- تا 8/0 ولت انجام گردید. پیک اکسیداسیون مشخصی برای دوپامین در ...

In this paper, we have tried to predict earthquake events in a cluster of seismic data on pacific ring of fire, using multivariate adaptive regression splines (MARS). The model is employed as either a predictor for a sequence prediction task, or a binary classifier for a sequence recognition problem, which could alternatively help to predict an event. Here, we explain that sequence prediction/r...
