Polyethylene (PE) is one the most used plastics worldwide for a wide range of applications due to its good mechanical and chemical resistance, low density, cost efficiency, ease of processability, non-reactivity, low toxicity, good electric insulation, and good functionality. However, its high flammability and rapid flame spread pose dangers for certain applications. Therefore, different flame-retardant (FR) additives are incorporated into PE to increase its flame retardancy. In this review article, research papers from the past 10 years on the flame retardancy of PE systems are comprehensively reviewed and classified based on the additive sources. The FR additives are classified in well-known FR families, including phosphorous, melamine, nitrogen, inorganic hydroxides, boron, and silicon. The mechanism of fire retardance in each family is pinpointed. In addition to the efficiency of each FR in increasing the flame retardancy, its impact on the mechanical properties of the PE system is also discussed. Most of the FRs can decrease the heat release rate (HRR) of the PE products and simultaneously maintains the mechanical properties in appropriate ratios. Based on the literature, inorganic hydroxide seems to be used more in PE systems compared to other families. Finally, the role of nanotechnology for more efficient FR-PE systems is discussed and recommendations are given on implementing strategies that could help incorporate flame retardancy in the circular economy model.

Semantic web services have received a significant amount of attention in the last years and many frameworks, algorithms and tools leveraging them have been proposed. Nevertheless surprisingly little effort has been put into the evaluation of the approaches so far. The main blocker of thorough evaluations is the lack of large and diverse test collections of semantic web services. In this paper we analyze requirements on such collections and shortcomings of the state-of-the-art in this respect. Our contribution to overcoming those shortcomings is OPOSSum, a portal to support the community to build the necessary standard semantic web service test collections in a collaborative way. We discuss how existing test collections have been integrated with OPOSSum, showcase the benefits of OPOSSum by an illustrative use case and outline next steps towards better standard test collections of semantic web services.

Abstract Backgorund. While there has been a growth of research on health and the Syrian conflict, most such research covers Syrian refugees. There is limited information about the scope and focus of research on health and population inside Syria. While there are several systemtic and scoping literarure reviews of health of Syrian refugees, there has not been a sccoping review of research literature on health issues inside Syria. Methods. As part of a broader scoping review covering January 2011 to December 2019, we examined English-language conflict-related research papers that studied health issues inside Syria and focused on Syrians or those permanently resident in Syria. We classified research articles based on the major thematic areas studied. We abstracted bibliometric information, study characteristics, funding statements and reported key limitations and challenges of conducting research. To gain additional insights or data, we examined separately publications reporting field and operational activities as well as personal reflections and narrative accounts of first-hand experiences inside Syria. Results. Of 2,088 papers identified in the scoping review, 708 (34%) exclusively focus on health issues of Syrians inside Syria, of which 350 (49%) are conflict-related with. Of conflict-related publications, 89 (25%) are research papers. Annual volume of research increased over time, from one publication in 2013 to 27 publications in each of 2018 and 2019. Damascus is the most frequently studied governorate (n=33), followed by Aleppo (n=25). Papers used a wide range of research methodologies, primarily quantitative (n=68). The country of institutional affiliation(s) of first and last authors are Syria (n=30, 20 respectively), the United States (n=25, 19 respectively) or the United Kingdom (n=12, 10 respectively). Themes most covered were health status, health system and humanitarian assistance, response or needs (n=38, 32, 26 respectively). Thirty one publications presented field and operational activities and eight publications were reflections or first-hand personal accounts of experiences inside Syria. Authors encountered contextual, methodological and administrative challenges in doing research on health inside Syria. Conclusions. Although it is commonly stated that Syria is among the most documented of recent wars, our analysis shows that a relatively limited number of research studies focused on health or populations inside Syria have been published over the nine years of the conflict. Beyond the need to increase the volume of research, it is important to address the knowledge gaps identified in this review.

Definitive diagnosis of Johne’s disease in ruminants depends on confirming the presence of the causative bacterium, Mycobacterium avium subsp. paratuberculosis, in tissues of the host. This is readily achieved in most ruminant species by culture. However, culture of clinical specimens from sheep in many countries has been unrewarding. Such a culture from sheep was achieved recently in Australia by using a radiometric culture medium. The aims of the present study were to evaluate the culture of M. aviumsubsp. paratuberculosis from sheep by using modified BACTEC 12B radiometric medium, to determine the sensitivity of culture in relation to histopathology, and to evaluate a range of solid media. Culture of M. avium subsp. paratuberculosisfrom sheep with Johne’s disease is a sensitive method of diagnosis: intestinal tissues from all 43 animals with multibacillary disease and all 22 animals with paucibacillary disease were culture positive, while 98% of feces from 53 animals with multibacillary disease and 48% of feces from 31 animals with paucibacillary disease were culture positive. Of sheep without histological evidence of Johne’s disease from infected flocks, intestinal tissue from 32% of 41 were culture positive, while feces from 17% of 41 were culture positive. Consequently, culture is recommended as the “gold standard” test for detection of ovine Johne’s disease. Of the wide range of solid media that were evaluated, only modified Middlebrook 7H10 and 7H11 agars, which were very similar in composition to modified BACTEC 12B medium, yielded growth of ovine strains of M. avium subsp.paratuberculosis. The sensitivity of detection of M. avium subsp. paratuberculosis on solid media was slightly lower than that in modified BACTEC 12B radiometric medium. Both egg yolk and mycobactin J were essential additives for growth of ovine strains of M. avium subsp.paratuberculosis in both liquid and solid media.

Jeeraka, commonly known as cumin (Cuminum cyminum Linn.) (Family: Umbelliferae), is a popular herbal plant in traditional ayurvedic medicine, which has since long used as antioxidant, gastric stimulant, anti-flatulence, anti-diarrheal, sprue, anthelmintic, galactagogue, diuretic, astringent, carminative. This plant is pharmacologically and clinically evaluated for various activities like antioxidant, aphrodisiac, antimicrobial, hepato-protective, and anti-inflammatory. It is promulgated to possess a wide range of many phytochemical constituents. The current review is presented to give a comprehensive account of all anti-cancer activities of cumin. It will be helpful to create interest towards cumin and may be useful in developing new and economical anti-cancer formulations with more therapeutic value. The part used of the selected plant is seed. As per retrospective review cumin seed, its essential oil, ethanoic extract and 1­(2­Ethyl, 6­Heptyl) Phenol (EHP), a biologically active compound formerly extracted by benzene are found having anti-cancer activity against 13 different cell lines of various origins and 6 animal models. Also, it can be used as chemopreventive ingredient in the herbal anti-cancer formulation. Total 8 research articles, peer viewed research papers, abstracts and classical texts were reviewed.

Entrepreneurship has become one of the vital activities for economic development. It is synonymous with job creation, innovation, improvement in the societal well-being and economic growth in developed and developing countries alike. There is great interest in entrepreneurship globally as well as in Malaysia. Over the past few years, many individuals, as well as families, are actively engaged with the small business. Also, in light of the 2013 GEM study, 12.7% of Americans are effectively occupied with beginning a business or are the proprietor/director of a business that is under three years of age. Simultaneously, the Halal industry, that represents the global Islamic economy, is the fastest-growing market in the world with $2.3 trillion market value. Halal entrepreneurs (Halalpreneurs) are the major contributors to this achievement as they constitute a significant portion of the total establishment in most of the Muslim countries. That is the reason Entrepreneurship has turned into a conventional term that depicts a wide range of practices that include being innovative, devilish and tricky. Entrepreneurship has been defined by many scholars, researchers, industry players, and academicians globally which have also been perceived in the same way by most of the economies around the world. However, the Islamic economy looks at the concept of ‘entrepreneurship’ in a different way and perceives it as ‘Halalpreneurship’. To define entrepreneurship in the halal industry, although, the term ‘Halalpreneurship’ is being used, surprisingly the term has not been defined properly yet. It is essential for the Muslim entrepreneurs to have a proper understanding of Halalpreneurship from Maqasid-al-Shariah perspective. Such point of view is crucial to justify the term in the Halal industry and differentiate from conventional entrepreneurs. On this context, this paper provides concept and definition of Halalpreneurship justifying from the perspective of Maqasid-al-Sharia’h. It also identifies the differences between Halalpreneurs and entrepreneurs using secondary resources available in the forms of literature, research papers, journal papers, articles, conference papers, online publications, etc. The findings of the study will clarify the concept of Halalpreneurship from Maqasid-al-Sharia’h perspective and recognize Halalpreneurs distinguished from conventional entrepreneurs.

Abstract. Recently, a standard test case suite for 2-D linear transport on the sphere was proposed to assess important aspects of accuracy in geophysical fluid dynamics with a "minimal" set of idealized model configurations/runs/diagnostics. Here we present results from 19 state-of-the-art transport scheme formulations based on finite-difference/finite-volume methods as well as emerging (in the context of atmospheric/oceanographic sciences) Galerkin methods. Discretization grids range from traditional regular latitude–longitude grids to more isotropic domain discretizations such as icosahedral and cubed-sphere tessellations of the sphere. The schemes are evaluated using a wide range of diagnostics in idealized flow environments. Accuracy is assessed in single- and two-tracer configurations using conventional error norms as well as novel diagnostics designed for climate and climate–chemistry applications. In addition, algorithmic considerations that may be important for computational efficiency are reported on. The latter is inevitably computing platform dependent. The ensemble of results from a wide variety of schemes presented here helps shed light on the ability of the test case suite diagnostics and flow settings to discriminate between algorithms and provide insights into accuracy in the context of global atmospheric/ocean modeling. A library of benchmark results is provided to facilitate scheme intercomparison and model development. Simple software and data sets are made available to facilitate the process of model evaluation and scheme intercomparison.
