<p>Pharmaceuticals cured deadly diseases and enhance the life spans of human beings. But, in the past decade, pharmaceuticals have risen as “contaminants of emerging concern” around the world. The persistence and resistance of pharmaceuticals lead to their accumulation in water bodies. The inefficiency of conventional WWTPs to remove pharmaceuticals also contributed to their environmental presence. Thus, the urgent need for sustainable and economically feasible remediation techniques has become evident. The present study describes the sorption of Acetaminophen from aqueous systems with engineered biochar. The biochars were developed from Mg/Al layered double hydroxides impregnated rice husk biomass at 500 and 700 ℃ in an atmosphere controlled muffle furnace.  The developed engineered biochar was characterized by using CHNS analyzer, ICP-OES, SEM, SEM-EDX, TEM, FTIR, and XRD. Engineered biochar was applied for aqueous pharmaceutical removal in batch mode through pH, isotherm, and kinetic studies. The effect of pyrolysis temperature, pH, concentration, dose, contact time, and sorption temperature have been evaluated. Engineered biochar prepared at 700 ℃ shows significantly higher removal of pharmaceutical as compared to Engineered biochar prepared at 500 ℃ as well as pristine biochar.</p>

This chapter explores the articulations that have emerged over the last half century between various types of holism, Chinese medicine and systems biology. Given the discipline’s historical attachments to a definition of ‘medicine’ that rather narrowly refers to biomedicine as developed in Europe and the US from the eighteenth century onwards, the medical humanities are not the most obvious starting point for such an inquiry. At the same time, they do offer one advantage over neighbouring disciplines like medical history, anthropology or science and technology studies for someone like myself, a clinician as well as a historian and anthropologist: their strong commitment to the objective of facilitating better medical practice. This promise furthermore links to the wider project of critique, which, in Max Horkheimer’s definition of the term, aims at change and emancipation in order ‘to liberate human beings from the circumstances that enslave them’. If we take the critical medical humanities as explicitly affirming this shared objective and responsibility, extending the discipline’s traditional gaze is not a burden but becomes, in fact, an obligation.

To displace a character in time is to depict a character who becomes acutely conscious of his or her status as other, as she or he strives to comprehend and interact with a culture whose mentality is both familiar and different in obvious and subtle ways. Two main types of time travel pose a philosophical distinction between visiting the past with knowledge of the future and trying to inhabit the future with past cultural knowledge, but in either case the unpredictable impact a time traveller may have on another society is always a prominent theme. At the core of Japanese time travel narratives is a contrast between self-interested and eudaimonic life styles as these are reflected by the time traveller's activities. Eudaimonia is a ‘flourishing life’, a life focused on what is valuable for human beings and the grounding of that value in altruistic concern for others. In a study of multimodal narratives belonging to two sets – adaptations of Tsutsui Yasutaka's young adult novella The Girl Who Leapt Through Time and Yamazaki Mari's manga series Thermae Romae – this article examines how time travel narratives in anime and live action film affirm that eudaimonic living is always a core value to be nurtured.

In the midst of increasing globalization, the past two decades have observed huge inflow of outside capital in the shape of direct and portfolio investment. The increase in capital mobility is due to contact between the different economies across the globe. The growing liberalization in the capital market leads to the growth of various financial products and services. Over the past decade, the Indian capital market has witnessed numerous changes in the direction of developing the capital markets more robust. With the growing Indian economy, the larger inflow of funds has been fetched into the capital markets. The government is continuously working on investor’s education in order to increase retail participation in the Indian stock market. The habits of the risk-averse middle class have been changing where these investors started participating in the Indian stock market. It is an explored fact that human beings are irrational and considering this fact becomes imperative to investigate factors that influence the trading decisions. In this research, ‘an attempt has been made to investigate various factors that affect the individual trading decision’. The data has been collected from various stockbroking firms and from clients of those stockbroking firms their opinions were recorded by means of a questionnaire. Data collected through the structured questionnaire, 33 questions were prepared which was given to the 330 respondents on the basis of convenience sampling out of which 220 individuals filled questionnaire, the total of 200 questionnaires was included in the study after eliminating the incomplete questionnaire. Various factors are being explored from the literature and then with the help of factor analysis some of the most influential factors have been explored. Factors like overconfidence, optimism, cognitive bias, herd behavior, advisory effect, and idealism are the factors which influenced the trading decision of the investors the most. Such kind of a study is contributing in the area of behavioral finance as a trading decision is an important aspect while investing in the stock market. And this kind of study would be helping and assisting financial advisors to strategies for their clients in making the right allocation and also the policy maker and market regulators to come up with better reforms for the Indian stock markets.

: Cancer is one of the most serious health concerns in 21st century whose prevalence is beyond boundaries and can affect any organ of human beings. The conventional chemotherapeutic treatment strategies lack specificity to tumours and are associated with toxic effects on immune system and other organ systems. In the past decades, there has been a continuous progress in the development of smart nanocarrier systems for target specific delivery of drugs against variety of tumours including intracellular gene-specific targeting. These nanocarriers are able to recognize the tumour cells and deliver the therapeutic agent in fixed proportions causing no or very less harm to healthy cells. Nanosystems have modified physicochemical properties, improved bioavailability and long retention in blood which enhances their potency. A huge number of nanocarrier based formulations have been developed and are in clinical trials. Nanocarrier systems include polymeric micelles, liposomes, dendrimers, carbon nanotubes, gold nanoparticles, etc. Recent advancements in nanocarrier systems include mesoporous silica nanoparticles (MSNs), metal organic frame works and quantum dots. In the present review, various nanocarrier based drug delivery systems along with their applications in the management of cancer have been described with special emphasis on MSNs.

The stories in Qur'an are Allah’s decrees which convey more beau-tiful values beyond any religious text ever written. It is the holiest scripture and is written  in a wonderful, understandable, and attract-ive language humbly conveying a vast amount of information about life and events that happened in the past. It’s aim is to be an object of reflection for human beings living in this age and the future. Even more so, the stories in Al-Qur'an also entail an educative function providing learning materials,  and teaching methods, regarding the transformative power of Islam and the internalization of true religious values.

Help towards understanding the human and religious functions of tradition comes from such sociologists as Peter Berger, Anthony Giddens, and Edward Shils. Tradition by Shils continues to illuminate how, although human beings modify inherited beliefs and change traditional patterns of behaviour, the new always incorporates something of the past. Shils takes a global view of tradition; it embodies everything individuals inherit when born into the world. It is through tradition that new members of society begin to identify themselves. The bearers of tradition may be not only official but also ‘learned’ and ‘ordinary’. Shils dedicates many further pages to changes in traditions and the forces leading to these changes. What sociologists like Giddens say about globalization also affects theological reflection on tradition. Surprisingly, the very few theologians who have published on tradition have ignored the sociologists.

Philosophers have not been sceptical only about metaphysics or religious beliefs. There are a great number of other beliefs generally held which they have had at least as much difficulty in justifying, and in the present article I ask questions as to the right philosophical attitude to these beliefs in cases where to our everyday thought they seem so obvious as to be a matter of the most ordinary common sense. A vast number of propositions go beyond what is merely empirical and cannot be seen to be logically necessary but are still believed by everybody in their daily life. Into this class fall propositions about physical things, other human minds and even propositions about one's own past experiences based on memory, for we are not now ‘observing’ our past. The phenomenalist does not escape the difficulty about physical things, for he reduces physical object propositions, in so far as true, not merely to propositions about his own actual experience but to propositions about the experiences of other human beings in general under certain conditions, and he cannot either observe or logically prove what the experiences of other people are or what even his own would be under conditions which have not yet been fulfilled. What is the philosopher to say about such propositions? Even Moore, who insisted so strongly that we knew them, admitted that we did not know how we knew them. The claim which a religious man makes to a justified belief that is neither a matter of purely empirical perception nor formally provable is indeed by no means peculiar to the religious. It is made de facto by everybody in his senses, whether or not he realizes that he is doing so. There is indeed a difference: while everyone believes in the existence of other human beings and in the possibility of making some probable predictions about the future from the past, not everybody holds religious beliefs, and although this does not necessarily invalidate the claim it obviously weakens it.

✓ In his 1982 Cushing oration, a distinguished philosopher, author, and discerning critic presents a distillate of his phenomenally wide range of personal experience and his familiarity with the great books and teachers of the present and the past. He explores the differences and relationships between human beings, brute animals, and machines. Knowledge of the brain and nervous system contribute to the explanation of all aspects of animal behavior, intelligence, and mentality, but cannot completely explain human conceptual thought.

Human beings regularly 'mentally travel' to past and future times in memory and imagination. In theory, whether an event is remembered or imagined (its ‘mnemicity’) underspecifies whether it is oriented towards the past or the future (its ‘temporality’). However, it remains unclear to what extent the temporal orientation of such episodic simulations is cognitively represented separately from their status as memories or imagination. To address this question, we investigated whether episodic simulations are more easily distinguishable in memory by virtue of their temporal orientation or their mnemicity. In three experiments (N = 360), participants were asked to generate and later recall events differing along the lines of temporal orientation (past/future) and mnemicity (remembered/imagined). Across all of our experiments, we consistently found that participants were more likely to confuse in recall event simulations that shared the same temporal orientation rather than the same mnemicity. These results show that the temporal orientation of episodic representations can be cognitively represented separately from their mnemicity and have implications for debates about the role of temporality in episodic simulation.
