Thermal and morphology characterization study of bio-active poly(amide-imide) based nanocomposites reinforced with modified SiO2 nanoparticle with poly(vinyl alcohol)
Among the nanoparticles (NPs), the amorphous SiO2 NPs are very useable, because of their important characteristics for different applications, such as mechanical performance, thermal properties, and biodegradability effects. For this manifest features SiO2 NPs were used as filler in this study. Firstly, these NPs were modified with poly(vinyl alcohol) (PVA). Then, the poly(amide-imide) (PAI) wa...


A 21-Event, 4,000-Year History of Surface Ruptures in the Anza Seismic Gap, San Jacinto Fault, and Implications for Long-term Earthquake Production on a Major Plate Boundary Fault
Paleoseismic work completed at Hog Lake on the San Jacinto Fault (SJF) near Anza, California, indicates that at least 21 surface ruptures have occurred in the Anza Seismic gap over the past 4,000 years. The ages of the ruptures are constrained by 111 radiocarbon dates, 97 of which fall in stratigraphic order. The average recurrence interval for all ruptures for this period is about 185 ± 10...
Confucian pluralism and China's dream of a harmonious world
This article will critique three aspects of the conservative re-sacralization project deemed incongruent with China’s dream of a harmonious world. The first pertains to the prevailing Han-centric rendition of the Confucian tradition. Rebuttals are made in support of an emerging multicultural ‘global Confucianism’, an international movement that would further the Chinese quest ...


How Chinese labour NGOs legitimize their identity and voice
This article analyses the legitimation strategies of Chinese labour non-governmental organizations (NGOs). Given the relative newness of NGOs as an organizational form in China and the precarious space they operate in, their survival and development are not primarily a question of establishing autonomy and avoiding state control, as emphasized in the literature on Chinese associations, but rath...
International actors in NIMBY controversies: Obstacle or opportunity for environmental campaigns?
The present case study examines whether international actors constitute an obstacle or opportunity for environmental campaigns against the siting of controversial facilities. Drawing upon field research carried out in Beijing, China, from 4 March until 10 April 2013, this article investigates the siting of the Nangong waste incinerator between the project’s announcement (2010) and conclus...


Children and youth NGOs in China: Social activism between embeddedness and marginalization
The proliferation of civic groups has been one of the most intriguing features of China’s societal transformation over the past three decades. The massive spread of non-governmental organizations (NGOs) has given rise to a broad debate among China scholars about the nature of Chinese state–NGO relations. Several authors have developed theoretical concepts that highlight and explain ...
Electrophysical characteristics of polyurethane/organo-bentonite nanocomposites
Modification of the Egyptian Bentonite (EB) was carried out using organo-modifier namely; octadecylamine ODA. Before the modification, the cation exchange capacity (CEC) of the EB was measured, also it was purified from different impurities using HCl and distilled water. The Organo-bentonite OB was characterized using IR, XRD, and TEM. PU/ODA-B nanocomposites were prepared by in situ polymeriza...

New heavy aggregate for offshore petroleum pipeline concrete coating Central West Sinai, Egypt
In this paper the local materials used in concrete mix are studied in a manner that they can resist the aggressive marine environment and mechanical damage, which can occur at several stages during transportation, construction and installation of the pipelines. In earlier studies we succeeded in finding the Egyptian ilmenite ore adequate for concrete weight coating and already utilized for many...
Multifractal analysis of slacken surface in hydrocarbon molecules through fuel additives
This paper investigates the effect of organic fuel additives (Bio-Glycerol) on fuel savings, emission reduction and extend engine life. Using this enzyme, a motor cycle is tested five times. The test report shows the reduction in the release of carbon monoxide (CO) and hydrocarbon upto 60%. The use of organic fuel additives in diesel vehicles for different periods of time reveals the reduction ...

Evaluation of various techniques for separation of non-polar modifier concentrates from petroleum waxy by-products
Two petroleum waxy by-products (light and middle slack wax crudes) were evaluated for separation of non-polar modifiers by using different techniques. The results showed that, the light slack wax is selected as a suitable wax for separation of n-alkanes with even number of carbon atoms ranging from C20 to C26 for their high n-paraffin contents and can be used as non-polar structural modifiers. ...
The emerging role of redox-sensitive Nrf2-Keap1 pathway in diabetes
The pathogenic processes involving in the development of diabetes range from autoimmune destruction of pancreatic β-cells with consequent insulin deficiency to abnormalities that result in resistance to insulin action. The major contributing factor for excessive β-cell death includes oxidative stress-mediated mitochondrial damage, which creates an imbalance in redox homeostasis. Yet, β-cells...

Novel therapeutic approaches for diabetic nephropathy and retinopathy
Diabetes mellitus is a chronic disease that in the long-term increases the microvascular and macrovascular degenerative complications thus being responsible for a large part of death associated with diabetes. During the years, while preventive care for diabetic patients has improved, the increase in the prevalence of diabetes worldwide is continuous. The detrimental effects of diabetes mellitus...
Is Narcolepsy a classical autoimmune disease?
Narcolepsy is a neurological disorder characterized by excessive daytime sleepiness. It is caused by the loss of orexin producing neurons in the lateral hypothalamus. Current evidences suggest an autoimmune mediated process causing the specific loss of orexin neurons. The high association of the disease with the HLA DQB1*06:02, as well as the link with environmental factors and are important cl...
Immunogenicity of Meningococcal quadrivalent (Serogroup A, C, W135 and Y) Tetanus Toxoid conjugate vaccine: Systematic review and meta-analysis
Meningococcal meningitis represents one of the leading cause of bacterial meningitis in developed countries. Among the thirteen described serogroups, only five are usually responsible of invasive infections making immunisation against multiple serogroups the best strategy to protect individuals from this disease. Herein we carried out a systematic review and meta-analysis, in accordance with th...
Late Pleistocene relic Ultisols and Alfisols in an alluvial fan complex in coastal Tuscany
Detailed stratigraphic, sedimentary facies and palaeosol analyses were performed on an outcrop on Late Quaternary deposits in the coastal area of Tuscany. The outcrop was selected as representative of one of the major Quaternary alluvial fan complexes of Central Italy, the ancient Cecina river fan, and as showing contrasting, if related, palaeosols. The oldest relic palaeosol was identified as ...
