Kinetic Equilibrium

In many aquifers around the world, there exists the issue of abnormal concentrations of Fe and Mn in groundwater. Although it has been recognized that the main source of this issue is the release of Fe and Mn from aquifer sediments into groundwater under natural environmental conditions, there lacks enough reliable scientific evidence to illustrate whether the pollutants imported from anthropogenic activities, such as organics, can increase this natural release. On the basis of time series analysis and comparative analysis, the existence of an increasing effect was verified through laboratorial leaching test, and the impacts of aquatic chemical environment conditions, such as pH, on the effect were also identified. The results showed that the increase of organics in groundwater made the release of Fe and Mn more thorough, which was favorable for the increase of groundwater concentrations of Fe and Mn. The higher the contents of Fe- and Mn-bearing minerals in aquifer sediments, the higher the concentrations of Fe and Mn in groundwater after the release reaches kinetic equilibrium. Lower pH can make the leaching more thorough, but the neutral environment also increases the amount of Mn. It can be deduced that the pollutants such as organics imported by anthropogenic activities can indeed increase the releases of Fe and Mn from aquifer sediments into groundwater, thus worsening the issue of groundwater Fe and Mn pollution. The findings provide a deeper insight into the geochemical effects of Fe and Mn in the natural environment, especially in the groundwater system.

Insight Into

The canine heartworm is a common and serious nematode parasite of domestic dogs in many parts of the world. Although nematode neuroanatomy is fairly well documented, the emphasis has been on sensory anatomy and primarily in free-living soil species and ascarids. Lee and Miller reported on the muscular anatomy in the heartworm, but provided little insight into the peripheral nervous system or myoneural relationships. The classical fine-structural description of nematode muscle innervation is Rosenbluth's earlier work in Ascaris. Since the pharmacological effects of some nematacides currently being developed are neuromuscular in nature, a better understanding of heartworm myoneural anatomy, particularly in reference to the synaptic region is warranted.

Insight Into

This essay examines a polemic between two Baudelaire critics of the 1930s, Jean Cassou and Benjamin Fondane, which centered on the relationship of poetry to progressive politics and metaphysics. I argue that a return to Baudelaire's poetry can yield insight into what seems like an impasse in Cassou and Fondane. Baudelaire provides the possibility of realigning metaphysics and politics so that poetry has the potential to become the space in which we can begin to think the two of them together, as opposed to seeing them in unresolvable tension. Or rather, the tension that Baudelaire animates between the two allows us a new way of thinking about the role of esthetics in moments of political crisis. We can in some ways see Baudelaire as responding, avant la lettre, to two of his early twentieth-century readers who correctly perceived his work as the space that breathes a new urgency into the questions of how modern poetry relates to the world from which it springs and in which it intervenes.

Status Of Women

Written almost half a century apart, Rajmohan’s Wife (1864) and The Home and the World (1916) can be read as women centric texts written in colonial India. The plot of both the texts is set in Bengal, the cultural and political centre of colonial India. Rajmohan’s Wife, arguably the first Indian English novel, is one of the first novels to realistically represent ‘Woman’ in the nineteenth century. Set in a newly emerging society of India, it provides an insight into the status of women, their susceptibility and dependence on men. The Home and the World, written at the height of Swadeshi movement in Bengal, presents its woman protagonist in a much progressive space. The paper closely examines these two texts and argues that women enact their agency in relational spaces which leads to the process of their ‘becoming’. The paper analyses this journey of the progress of the self, which starts with Matangini and culminates in Bimala. The paper concludes that women’s journey to emancipation is symbolic of the journey of the nation to independence.

The World Health Organization (WHO) has recently announced the spread of novel coronavirus (nCoV) globally and has declared it a pandemic. The probable source of transmission of the virus, which is from animal to human and human to human contact, has been established. As per the statistics reported by the WHO on 11th April 2020, data has shown that more than sixteen lakh confirmed cases have been identified globally. The reported cases related to nCoV in India have been rising substantially. The review article discusses the characteristics of nCoV in detail with the probability of potentially effective old drugs that may inhibit the virus. The research may further emphasize and draw the attention of the world towards the development of an effective vaccine as well as alternative therapies. Moreover, the article will help to bridge the gap between the new researchers since it’s the current thrust area of research.

AB InBev is today’s uncontested world leader of the beer market. It represents over 20 per cent of global beer sales, with more than 450 million hectolitres a year flowing all around the world. Its Belgian predecessor, Interbrew, was a success story stemming from the 1971 secret merger of the country’s two leading brewers: Artois and Piedboeuf. Based on first-hand material originating from company and private archives as well as interviews with managers and key family actors, this is the first study to explore the history of the company through the nineteenth and twentieth centuries.The story starts in the mid-nineteenth century with the scientific breakthroughs that revolutionized the beer industry and allowed both Artois and Piedboeuf to prosper in a local environment. Instrumental in this respect were the respective families and their successive heirs in stabilizing and developing their firms. Despite the intense difficulties of two world wars in the decades to follow, they emerged stronger than ever and through the 1960s became undisputed leaders in the national market. Then, in an unprecedented move, Artois and Piedboeuf secretly merged their shareholding in 1971, though keeping their operations separate until 1987 when they openly and operationally merged to become Interbrew. Throughout their histories Artois, Piedboeuf, and their successor companies have kept a controlling family ownership. This book provides a unique insight into both the complex history of these three family breweries and their path to becoming a prominent global company, and the growth and consolidation of the beer market through the nineteenth and twentieth centuries.

Psalm 104 is a majestic hymn to creation, a dynamic corollary to the more formal presentation of the creation of the world in Genesis 1. Reflection upon some of the passages provides us with insight into the biblical author’s appreciation for nature, an attitude that needs to inspire us in this age of ecological crisis. Though the biblical text is unaware of such an ecological crisis; nonetheless, passages shine forth that can speak to us in our modern age of global warming and environmental collapse.

Insight Into

Drawing from Van Gennep and Caffee’s conceptualization of liminality, this autoethnographic narrative portrays the author’s rites of passage into academia and through the death of her father. These fundamental developmental transitions and losses emerged concomitantly within the backdrop of a pandemic, further cloaking the world in grief and disequilibrium. Incorporating the voice of the personal as professional, the author portrays her existential struggles in relinquishing her cherished role as a palliative care social worker and living through her dad’s final months during a time of restricted social interaction. Interwoven throughout the narrative appear stories of strife, hope, grief, and professional epiphanies of purpose and insider privilege. The paper embraces both personal and professional conflicts and provides insight into the ways in which the unique setting of a pandemic can provide clarity for navigating the liminal states of separation, transition, and incorporation.

The World Trade Organization (WTO) Agreement on the Application of Sanitary and Phytosanitary Measures (SPS Agreement) relies on scientific evidence as a conclusive risk assessment criterion, which ignores the inherent limitations of science. This article highlights certain trade-restrictive effects of scientific evidence and comments on the Agreement’s aversions to precautionary measures and the consumer concern of the harmful effects of biotech products that may be necessary to protect public health and biosecurity in many WTO Member States. These measures and concerns have become pressing issues due to surging consumer awareness and vigilance concerning environmental protection and food safety. The Agreement is yet to overcome the weaknesses of its endorsed international standardising bodies, the problematic definition of scientific evidence and treatment of justification for scientific risk assessment methods and the implementation difficulties faced by most developing states. This article analyses these issues under the provisions of the Agreement and the interpretations of the WTO Dispute Settlement Body in disputes involving SPS matters, which fall short of addressing scientific uncertainty surrounding biotech products and their associated risks.

Mineral Depletion

In 1927 a study at King's College, University of London, of the chemical composition of foods was initiated by Dr McCance to assist with diabetic dietary guidance. The study evolved and was then broadened to determine all the important organic and mineral constituents of foods, it was financed by the Medical Research Council and eventually published in 1940. Over the next 51 years subsequent editions reflected changing national dietary habits and food laws as well as advances in analytical procedures. The most recent (5th Edition) published in 1991 has comprehensively analysed 14 different categories of foods and beverages. In order to provide some insight into any variation in the quality of the foods available to us as a nation between 1940 and 1991 it was possible to compare and contrast the mineral content of 27 varieties of vegetable, 17 varieties of fruit, 10 cuts of meat and some milk and cheese products. The results demonstrate that there has been a significant loss of minerals and trace elements in these foods over that period of time. It is suggested that the results of this study cannot be taken in isolation from recent dietary, environmental and disease trends. These trends are briefly mentioned and suggestions are made as to how the deterioration in the micronutrient quality of our food intake may be arrested and reversed.
