Polyacrylate polymer (PA) was modified with graphene oxide (GO) and the obtained composites were applied as coatings for controlled-release coated urea (CRU). The physicochemical properties of the different PA/GO coatings were characterized in detail and the nitrogen-release characteristics of the obtained CRU samples were determined in water at 25 ◦C. The experimental results revealed that add...

Phosphatidic acid (PA) is a precursor metabolite for phosphoglycerolipids and also for galactoglycerolipids, which are essential lipids for formation of plant membranes. PA has in addition a main regulatory role in a number of developmental processes notably in the response of the plant to environmental stresses. We review here the different pools of PA dispatched at different locations in the ...

Atopic dermatitis (AD) is a chronic relapsing skin disease, associated with impaired barrier function and characterized by poorly defined pruritic, erythematous lesions. In this study, the efficacy of new topical cream (IALUSET VITAL®), containing hyaluronic acid extract Salvia haenkei, in reducing symptoms moderate AD adults was investigated. This study randomized, double blind, vehicle-contro...

This study investigates the effects of chlorothalonil (CLT) on chemical oxygen demand (COD) and dissolved organic carbon (DOC) in pilot-scale horizontal subsurface flow constructed wetlands (HSSFCW) planted with Phragmites australis. Physicochemical parameters of influent and effluent water samples, microbial population counting methods and statistical analysis were used to evaluate the influen...

Physical chemistry is the branch of chemistry that establishes and develops the principles of the subject in terms of the underlying concepts of physics and the language of mathematics. Its concepts are used to explain and interpret observations on the physical and chemical properties of matter. Physical chemistry is essential for developing and interpreting the techniques used to determine str...

Safety is the most important part of any kind assiduity safety. In extreme circumstances, safety-related negligence could result in destruction expensive clothing or loss human life. Every min-ing diligence adhere to a few basic preventative measures order avoid generally unwelcome wonders. The component at this time communication continuously monitor various pa-rameters and take appropriate ac...

Many applications require that we learn the pa­ rameters of a model from data. EM (E xpectation­ Maximization) is a method for learning the pa­ rameters of probabilistic models with missing or hidden data. There are instances in which this method is slow to converge. Therefore, sev­ eral accelerations have been proposed to improve the method. None of the proposed acceleration methods are theore...

The origin of the concept of a molecular complex between oxygen and hemoglobin can be traced to Stokes, a century and a half ago. Subsequently, physicochemical concepts of equilibria provided a path to quantitative formulations of these ligand-receptor interactions. Then, it took a quarter of a century before a proper format was prepared in terms of four stoichiometric equilibria and their asso...
