TL;DR: The main purpose of as mentioned in this paper is to focus on the catalytic reactivity of different kinds of catalysts in oxidation, dehydration, acetylation, etherification, esterification, acetalization, and ammoxidation process of glycerol conversion.
Abstract: The huge amount of glycerol obtained during the production of biofuels has led to the search of alternatives for the use of this by-product. New applications for this polyol as a low-cost raw material need to be developed and existing ones need to be expanded. To address this problem, production of value-added molecules from crude glycerol is an effective alternative method for its disposal by incineration. Thus, the ready bioavailability, renewability and unique structure of glycerol make it a particularly attractive starting point for the production of a large number of specialty chemicals. The main purpose of this review is to focus on the catalytic reactivity of different kinds of catalysts in oxidation, dehydration, acetylation, etherification, esterification, acetalization, and ammoxidation process of glycerol conversion. Typical products are citric acid, lactic acid, 1,3-dihydroxyacetone, 1,3-propanediol, dichloro-2-propanol, acrolein, hydrogen, and ethanol. Recent studies on the catalysts, reaction conditions and possible pathways are primarily discussed.

TL;DR: Bihemispheric tDCS may achieve the training-induced recovery of motor functions and foster greater functional recovery and CIMT alone appears effective in modulating local excitability but not in removing the imbalance in transcallosal inhibition.
Abstract: Background. Recovery of motor function after stroke may depend on a balance of activity in the neural network involving the affected and the unaffected motor cortices. Objective. To assess whether ...

TL;DR: The biggest challenges identified for low-income countries were little community awareness that breast cancer is treatable, inadequate advanced pathology services for diagnosis and staging, and fragmented treatment options, especially for the administration of radiotherapy and the full range of systemic treatments.
Abstract: The purpose of the Breast Health Global Initiative (BHGI) 2010 summit was to provide a consensus analysis of breast cancer control issues and implementation strategies for low-income and middle-income countries (LMCs), where advanced stages at presentation and poor diagnostic and treatment capacities contribute to lower breast cancer survival rates than in high-income countries. Health system and patient-related barriers were identified that create common clinical scenarios in which women do not present for diagnosis until their cancer has progressed to locally advanced or metastatic stages. As countries progress to higher economic status, the rate of late presentation is expected to decrease, and diagnostic and treatment resources are expected to improve. Health-care systems in LMCs share many challenges including national or regional data collection, programme infrastructure and capacity (including appropriate equipment and drug acquisitions, and professional training and accreditation), the need for qualitative and quantitative research to support decision making, and strategies to improve patient access and compliance as well as public, health-care professional, and policy-maker awareness that breast cancer is a cost-effective, treatable disease. The biggest challenges identified for low-income countries were little community awareness that breast cancer is treatable, inadequate advanced pathology services for diagnosis and staging, and fragmented treatment options, especially for the administration of radiotherapy and the full range of systemic treatments. The biggest challenges identified for middle-resource countries were the establishment and maintenance of data registries, the coordination of multidisciplinary centres of excellence with broad outreach programmes to provide community access to cancer diagnosis and treatment, and the resource-appropriate prioritisation of breast cancer control programmes within the framework of existing, functional health-care systems.

TL;DR: It is found that a thick interphase cannot produce high interfacial/interphase parameters and significant mechanical properties in nanocomposites because the filler size and aggregates/agglomerates also control these terms.
Abstract: In this study, several simple equations are suggested to investigate the effects of size and density on the number, surface area, stiffening efficiency, and specific surface area of nanoparticles in polymer nanocomposites. In addition, the roles of nanoparticle size and interphase thickness in the interfacial/interphase properties and tensile strength of nanocomposites are explained by various equations. The aggregates/agglomerates of nanoparticles are also assumed as large particles in nanocomposites, and their influences on the nanoparticle characteristics, interface/interphase properties, and tensile strength are discussed. The small size advantageously affects the number, surface area, stiffening efficiency, and specific surface area of nanoparticles. Only 2 g of isolated and well-dispersed nanoparticles with radius of 10 nm (R = 10 nm) and density of 2 g/cm3 produce the significant interfacial area of 250 m2 with polymer matrix. Moreover, only a thick interphase cannot produce high interfacial/interphase parameters and significant mechanical properties in nanocomposites because the filler size and aggregates/agglomerates also control these terms. It is found that a thick interphase (t = 25 nm) surrounding the big nanoparticles (R = 50 nm) only improves the B interphase parameter to about 4, while B = 13 is obtained by the smallest nanoparticles and the thickest interphase.

TL;DR: An understanding of the psychosocial, cultural, economic, organisational, and political factors influencing epilepsy causation, management, and outcome should be of high priority for future investigations.
Abstract: Epilepsy is a significant, but often underappreciated, health problem in Asia. Here, we systematically review the literature on epidemiology, aetiology, and management of epilepsy in 23 Asian countries. Prevalence estimates are available for only 11 countries from door-to-door surveys and are generally low. Figures for annual incidence in China and India are similar to those in the USA and Europe but lower than those reported from Africa and Latin America. There is a peak in incidence and prevalence in childhood, but a second peak in elderly people, as seen in developed countries, has not been documented. The main causes are head injuries, cerebrovascular disease, CNS infections, and birth trauma. Availability of epilepsy care depends largely on economic factors. Imaging and neurophysiological facilities are available in most countries, but often only in urban centres. Costly drugs, a large treatment gap, limited epilepsy surgery, and negative public attitude to epilepsy are other notable features of management in Asia. An understanding of the psychosocial, cultural, economic, organisational, and political factors influencing epilepsy causation, management, and outcome should be of high priority for future investigations.
