Generation of clean energy is one of the main challenges of the 21st century. Solar energy is the most abundantly available renewable energy source which would be supplying more than 50 of the global electricity demand in 2100. Solar cells are used to convert light energy into electrical energy directly with an appeal that it does not generate any harmful bi products, like greenhouse gasses. The manufacturing of solar cells is actually based on the types of semiconducting or non semiconducting (...) materials used and commercial maturity. From the very beginning of the terrestrial use of Solar Cells, efficiency and costs are the main focusing areas of research. The definition of so called emerging technologies sometimes described as including any technology capable of overcoming the Shockley-Queisser limit of power conversion efficiency 33.7 percent for a single junction device. In this paper, few promising materials for solar cells are discussed including their structural morphology, electrical and optical properties. The excellent state of the art technology, advantages and potential research issues yet to be explored are also pointed out. Md.

A major part of Ordinary Aesthetics has been to include the traditionally marginalized aesthetic categories excluded when studying beauty, truth, and goodness. These “negative aesthetics” are implicated in the construction, presentation, and sustenance of marginalized identities.

I will present some samples from the Persian poetry of Hafez and Rumi, as well as Punjabi couplets of Bulleh Shah and Shah Hussain, for a hermeneutic study that grounds the aesthetics of their Qalandari-themed literature in the usage of “negative” aesthetic categories. This exercise contains the promise of expanding the horizons for our field of sensibilities, by engaging with those social identities that have remained outside them and that too on their own terms.

For the sake of a respiratory philosophy, it makes sense to look to the East, since many Eastern traditions such as Sufism include breathwork in their somatic practices. In my paper, I aim to show how Rumi – a 13th century Muslim theologian and Sufi – used breath or nafas in his Persian poetry to outline how breathing is an originary phenomenon. My paper will take a few samples of his poetry to demonstrate how breath connotes a newness through the (...) “gift” of life that it endows upon us, and how the creative, endowing, and primal nature of breath is linked to an openness to the Divine Other and to others. Furthermore, for Rumi, every passing breath ushers in a new existence, annihilating its older form and thus creating an ontological sense in the reader of both the finiteness of existence through what has passed and the infinite possibilities it holds when the newness arrives. Bridging the finite and infinite through breath enables us to develop a respiratory ontology that aims to conceive of dualities through an interrelated perspective. This, I wish to argue, is the true promise of Rumi’s poetry for a philosophy of breathing. (shrink)

The credit crises experienced in the US in year 2008 is labeled as perhaps the most significant crises since the great depression. The roots of the crises were found in the default of the sub-prime mortgages and the failure occurred in both the US and the UK.

Note: Many types of nanosensors are designed using CP nanomaterials for nanobiological applications. (Conductive surface) The oxidation of conductive polymeric materials is easily altered by redox mechanisms, and the charge transfer properties of these materials are affected by structural parameters, such as diameter and dimensions. CP materials are able to provide sensitive and rapid responses to specific biological and chemical species. Techniques such as chemical polymerization are often used to make CP nanomaterials. Manufacturing strategies can be divided into three categories: (...) hard mold synthesis, soft mold synthesis, and mold-free synthesis. The most widely used conductive polymers in nanosensors are nanomaterials made from CP due to their unique chemical and electrical properties resulting from the properties of their pie-electron nanosystem. Many modeling and functionalization technologies are being developed to control the location, distribution, amount, or structure and orientation of biological nanomolecules at the nanomaterial level. Therefore, our level of contact between biological nanomolecules and nanomaterials is of particular importance in countless applications. Covalent and non-covalent modifications are two general methods for coupling biological molecules and CP nanomaterials. Covalent functionalization is a chemical process in which a strong bond or relationship between nanomaterials and biological molecules is formed. In many cases, surface chemical modifications are required to create active groups that can bind to biomolecules. Unlike covalent functionalization, in the non-covalent method, nanomolecules can be removed without destroying the geometric and electronic structure on the surface. Nanomaterials are formed. Conclusion : The large surface-to-volume ratio in nanostructures and the high potential for signal amplification provide ideal conditions for marking and detecting biological elements in the structure of nanosensors.

Child labour remains widespread in the urban slums of Bangladesh. Empirical studies indicate that various local-level factors drive poor families and children to engage in child labour. However, the role of structural factors and environmental realities is underrepresented in the current scholarship. This investigation examined the role of these factors in normalizing child labour in the slum communities of Dhaka. The researcher adapted a socio-ecological model to develop a conceptual framework for collecting qualitative data from the slum communities of two (...) recently urbanized areas of the city: Hazaribagh and Matuail. A five-month fieldwork project was carried out to conduct 40 semi-structured interviews and two focus group discussions with parents and community members. The data analysis resulted in the following findings. A lack of access to schooling pushed many children into labour. The opportunities for children’s employment in the informal sector remained abundant, and the absence of documents complicated law enforcement. Due to inconsistent adult income, many families are involved in child labour to increase their household income. Local employers chose children over adults for certain occupations due to their low wages and easy-to-control nature. Natural disasters, climate change, and family difficulties drove a large number of families to these slums, and informal employment opportunities for both adults and children drew them there. The shortage of playgrounds and specialized schooling shaped children’s tendency to work more. All together, child labour has become a cultural reality. Policies and interventions aiming to reduce child labour must influence these structural factors and provide support to families and children. (shrink)

This paper considers the foundation of self-realization and the sense of morality that could justify Arne Naess’s claim ‘Self-realization is morally neutral,’ by focusing on the recent debate among deep ecologists. Self-realization, the ultimate norm of Naess’s ecosophy T, is the realization of the maxim ‘everything is interrelated.’ This norm seems to be based on two basic principles: the diminishing of narrow ego, and the integrity between the human and non-human worlds. The paper argues that the former is an extension (...) of Plato’s idea of self-development or self-mastery while the latter is implicit in Aristotle’s holism. It defends that Self-realization is morally neutral only if the term ‘moral’ is considered in the Kantian sense. However, Naess reluctantly distinguishes between ethics and morality, which makes his approach less credible. The paper concludes that Aristotle’s notion of eudaimonia supports Self-realization to qualify as a virtue. (shrink)

Micro and nano-electromechanical systems ( MEMS / NEMS ) are devices in which the physical motion of a micro or nano-scale structure is controlled by an electronic circuit or vice versa.

Electrostatic nanocapacitors also benefit from a very short distance between their electrodes. Electrostatic nanocapacitors are unique in this respect. If the electrodes are far apart, like charges on their surface strongly repel each other. When the electrodes are placed closer together, the negative and positive charges on both sides balance these repulsive forces, and more total charge can be stored in a given area.

Note: The field-effect tunnel transistor nMOS is an experimental type of transistor. Even if its structure is very similar to a metal-oxide semiconductor field-effect transistor nMOS , the basic switching mechanisms in these two transistors differ from each other; nMOS instead of exhibiting thermionic emission modulation, changes through a quantum tunnel modulation 12> They change through a dam. The field-effect tunneling transistor nMOS, as an alternative to conventional CMOS by enabling the voltage supply (VDD) with ultra-low power consumption, enables energy-efficient (...) computing during the sub-threshold slope (SS) range. This type of device has a reverse-bias gate structure, which is usually called a tunnel field-effect transistor nMOS. For low power applications, nMOS is considered. This device has less static leakage current than a MOSFET and is more resistant to SCEs. The most outstanding feature of nMOS is the capacity to produce a reverse subthreshold swing (SS) of less than the 60 mV/decade thermal limit (at 300 K), which is related to common reverse mode nMOSs. A pseudo-thermal SS is achievable because the drain current in nMOSs is generated by source-to-channel carrier injection, which is often under the band tunneling radius. It is placed in the quantum mechanical band (BTBT). Transistor speed nMOS is proportional to the current. The higher the current, the faster the transistor will be able to amplify and charge (the sequential capacitor voltage). For a given transistor speed and maximum acceptable subthreshold leakage, the subthreshold slope thus defines a minimum threshold voltage. Decreasing the threshold voltage is an essential part of the idea to scale the constant amount of nMOS to overcome some challenges associated with the nMOS structure, such as its need for ultra-sharp doping profiles; however, such devices may suffer from gate leakage due to the presence of large vertical fields in the nMOS transistor structure.

This element belongs to the group of iron and cobalt elementsUsing particles from the microscale to the nanoscale provides benefits for various scientific fields, but because a large percentage of their atoms is on the surface, nanomaterials can be highly reactive and pose risks. have a potential for humans. Nanoparticles are of great interest due to their wide application, both in industry and (...) in the natural sciences. While natural materials have constant physical properties regardless of size, the size of a nanoparticle determines its physical and chemical properties. Therefore, the properties of a material change as its size approaches the nanoscale and the percentage of atoms on the surface of the material becomes significant. The important feature of all nano structures is that in which the number of surface atoms is more than the number of volume atoms. This ratio increases with decreasing nanoparticle size. Therefore, the size of the nanoparticle is considered its most important feature. The range of activity of nanoparticles depends on the nature and shape of the nanostructure. However, if the energy of the nanoparticle field is comparable to the energy of electromagnetic radiation and if in a certain range a wavelength with the occurrence of chemical reactions in materials Under irradiation, significant changes will be made in the activity of nanoparticles up to 100 nm in size. is the nanometer expected to be used for storage. Given the relatively large (physically speaking) storage devices we have now and the fact that we need gigabyte sizes in various areas, there is a high potential for activity in this There is a context. Each quantum dot consists of a discrete ball of several hundred atoms that can have one of two magnetic states. This allows them to contain a single bit of information (zero or one), as is customary in machine computing. In conventional hard disks, the data bits must be spaced far enough apart that they do not overlap. Quantum dots act as completely independent units that are not structurally connected, so they can become somewhat closer to each other. One of the new information storage tools is the use of nickel quantum dots in nanometer sizes, which are expected to be used to store terabytes of data. (shrink)

FinFET devices, compared to flat technology and using nanowires in the structureand (complementary metal oxide and semiconductor), < a i=8>have significantly faster switching and highercurrent density.Due to the reduction of the (...) scale of semiconductor components and integrated circuits to thenanometer range, in the FinFET nanotransistor, the reduction of scale causes more short channel effects, lessgate control, an exponential increase in leakage currents, severe process changes, and power densities tobecome unmanageable. The connection between the carbon and metal nanotubes used to connect the sourceand the drain forms the Schottky barrier (SB) in a FinFET nanotransistor. The formation of Schottky barriers inthe source and drain of a transistor causes a significant decrease in the drain current of FinFET nanotransistors. (shrink)

European colonialism is an extremely controversial affair in world history that is also discussed today. This paper explores the influence of these happenings as the world incorporates the culture of European in every step of life. Europe dominated almost the entire world and its people were leaders in science and technology. European languages, literature, and culture spread all over the globe. Decisions in Europe largely determined global events for centuries. The other continents did not approach European power until after WW1 (...) or WW2. Europe consisted of constantly competing nations, and this competition spurred development. Europe achieved world hegemony in the years after 1500 A.D., primarily due to technological advancements, scientific research, political development of nations with stable succession and continuity, and a culture dominated by Christianity. These advantages were translated into military power, projected all over the world. (shrink)

Note: In electrical conduction from a conductor to a semiconductor or an electrically changeable insulator, nanotubes depend on their molecular chiral structure and angle. Since carbon nanotubes are able to pass electric current through the ballistic transfer of electrons without friction from their surface-this current is a hundred times higher than the current that passes through a copper wire-the nanotube is an ideal choice for building nano memory cloud chips. Creating chipsNano memory cloud-Nano memory cloud is made of carbon nanotubes. (...) Although the discovery of small carbon nanotubes has been very resistant, flexible, and conductive, with dimensions equal to DNA strands, and the use of small organic molecules to absorb charge instead of charge storage capacitors in nanotype memory chips. Nanocrystals, whose use causes The life span of nano memories to increase, is involved. Indeed, using nanotechnology, the storage capacity of information can be increased by a thousand times or more. Storing information is a very important and necessary topic that can be addressed in different ways through the cloud and nano memories. One of the new tools for storing information is the use of nickel quantum dots in nanometer sizes, which are expected to be used to store terabytes of data. According to cloud nano memories, there is high potential for activity in this field. The structure and design of supercapacitors based on nanoelectronics store 100 times more charge than electrolyte types in the same volume and are charged and discharged much faster than batteries.

Oligophenylene vanillin nanowires (Si Silicon / Germanium Gi) , narrow structures whose diameter is only a few billionths of a meter but thousands or millions of times longer. They exist in various forms—made of metals, semiconductors, insulators, and organic compounds—and are used for applications in the fields of electronics, energy conversion, optics, and chemical sensing. Because of their extreme thinness, Oligophenylene vanillin nanowires with a (Si Silicon / Germanium Gi) structure are essentially one dimensional. Nanowires are quasi-one-dimensional materials, "their two (...) dimensions are on the nanometer scale." This one-dimensionality confers distinct electrical and optical properties. (shrink)

Rohingya refugee children in Bangladesh are forced into labour both inside and outside the camps for a wide range of reasons. This article examines this situation in relation to the access to education for those children living in the camps in Cox’s Bazar. Being informed by several perspectives concerning child labour and access to schooling in developing country contexts, this research work has adopted a qualitative approach to study various factors working behind this pressing issue. After collecting data by means (...) of qualitative methods, including non-participant observations and semi-structured interviews, the researcher has analyzed the findings with these informed perspectives. Results show that lack of formal identity, limited access to the formal labour market, absence of social sanctions against child employment, lack of aspirations, household composition, and substandard living conditions are some of the key factors that drive children to engage in various forms of labour, especially outside the camps. They often work in small workshops as labourers and in the host community households as domestic workers. Undocumented children are also reported to become victims of bonded labour, sex trade, and trafficking in the region. The author argues that a lack of formal education has compounded this issue into a severe humanitarian crisis which calls for immediate support and actions from local and international agencies.

An increase in the surface-to- volume ratio and changes in geometry and electronic structure have a strong impact on the chemical interactions of matter, and for example, the activity of small particles changes with changes in the number of atoms (and thus the size of the particles). Unlike today's nano-transistors, which behave based on the movement of a mass of electrons in matter, new devices follow the phenomena of quantum mechanics at the nano scale, in which the discrete nature of (...) electrons cannot be ignored. By reducing all the horizontal and vertical dimensions of the transistor, the electric charge density increases in different areas of the nano-transistor , or in other words, the number of electric charges per unit area of the nano-transistor increases.

After ratifying the Framework Convention for Tobacco Control in 2004, Bangladesh enacted anti-tobacco laws, policies, and administrative measures. Evidence suggests that the progress so far has not been significant, and Bangladesh will most likely fail to meet its target to become tobacco-free by 2040. This study undertakes a national-level political economy analysis to explore the dynamics that affect the processes of required tobacco policy reforms and implementation. Based on a desk review of pertinent pieces of literature and key informant interviews, (...) this research examines the political behavior of key individuals, institutional reform initiatives, and the government’s commitment to the tobacco control agenda. The findings indicate that the political will of becoming tobacco-free is explicitly present in key narratives. However, intra-government conflict of interests and incentives, the skewed commitment of government bodies, state-business nexus, incapacity of vital organizations, and the dubious role of key individuals and committees fail to translate this will into active implementation. The article concludes that the idea of tobacco control remains a strategic accommodation, and its implementation requires genuine commitment and wider public support. The government must confer adequate authority and resources to the national tobacco control cell and call for agencies to convene to the common of creating a tobacco-free Bangladesh. (shrink)

In the immersion method, nanowires have enough time to transfer from nanoparticle particles to cavities ; The formation step of uniform nanoparticles is done slowly and finally uniform nanowires are formed. Structural study with FESEM in the immersion method of single-stranded nanowires in all porosities and in a large area of nanowire particles are formed. Changing the Sr / Fe ratio does not change the morphology of the nanowires.

The paper discusses all the necessary factors to prove the enhanced purchase of supreme quality property company dealers like Prime LnadPvt. Ltd is a leading real estate company in Sri Lanka. However, the valuation of property is most vital for the real estate industry. It depends on the type of artifact, the real estate sector offers to its clients. For this industry, infrastructure quality is the most important factor. All the contributing factors, analyses reveal this lesson. This truth is supported by many theories and analyses to lead today’s provider, meeting the original demand factor of the mass people. (shrink)

Learning a second language is always a difficult task and so, children is given the task to do it in the elementary stage. It depends on various factors and combining that factors the result comes on. A favorable outcome results in when the teachers devote themselves to teach the younger the Achilles task as soon as possible. Sometimes the result become satisfactory but most of the time it doesn’t happen. And because of this reason, technological use on this teaching should (...) be performed after actually realizing in which pattern it will be most effective. The research on this matter should be applied to singular aged number of people. So, this research paper is based on Elementary level entered students’ characteristic of accepting vastly used English as a second language. The specific arena here selected is Bangladesh. Bangladesh is a developing country and recently, it has promoted to low profit country than under-developed country. Thus, it is very much in need to determine which technologies are of most value when it is applied to the system getting English learned by the elementary levelled entering students. Search the number learners of English are in the increasing percentage, mass of the newly developed tools are implemented on this English learning teaching system. (shrink)

Belt and Road Initiative (BRI) is a global infrastructure development project that ambitiously aims to connect Asia with European and African continents through land and sea corridors. China adopted this gigantic game-changing master plan in 2013 and spurred much speculation among scholars and policymakers worldwide. This article investigates the development of the project through the lens of global political geography and economy. From an international relations perspective, the authors consult relevant pieces of literature and focus on the international issues and (...) events concerning the development of the project using concepts of ideas, interests, and institutions within the scope of geopolitics and political economy. The analysis is performed by reviewing critical events and arguments related to the ideas, interests and institutions evolving around the implementation of BRI. Drawing from the analysis, the authors argue that the rise of China as a dominant global superpower largely depends on the success of the BRI, and this initiative will continue to generate politics among the international actors, multinational entities, and institutions. Despite widespread speculations, the project poses a substantive threat to the USA's global dominance and is likely to create more global development cooperation under Chinese leadership and vision.

The overall objective of the study was to examine the pros and cons of the participatory approach adopted in natural resource management in the ecologically protected areas of the Sundarbans mangrove of Bangladesh. A comparative study was done between the people who are involved and non-involved in this approach. Empirical data was collected through personal interviews with a structured questionnaire. The Gini coefficient was measured first and then embedded with the Lorenz curve to draw a line between perfect equality and (...) inequality vis-a-vis. The study revealed that the co-management built awareness in favor of biodiversity conservation and the efficient use of natural resources. Contradictorily, a segment of different hierarchical committees was involved in destructive activities like poisoning the wetlands for fishing. Therefore, a mixed outcome was found. The findings will help the policymakers in identifying the pitfalls and bottlenecks rooted in co-management. Hence, the study recommends revising the approach to ensure the community’s active participation on an equal basis and take action against them who degrade those resources. Exploring profitable alternative income-generating activities is warranted to narrow down the dependency on the Sundarbans mangrove’s natural resources. In order to address the tragedy of the commons, the study advocates for the unity of all knowledge ranging from science to humanistic scholarship for sound policymaking. (shrink)

The global response to child labour is based on the standards set by three major international conventions. This review examines the historical development of the conceptualizations of various forms of child labour, relevant views and perspectives, contemporary theoretical underpinnings, and policy suggestions. The emerging evidence shows that child labour incidences in all its forms have increased in many parts of the world, and the global target to eradicate child labour by 2025 seems unattainable. The evaluation indicates that the current global (...) age-based abolitionist policy to fight child labour has lost some ground. The covid-19 pandemic has worsened the situation and the worst forms of child labour have become even more widespread and deeply normalized in many contexts and communities. The current scholarship of child labour remains critically ignorant of the relevant societal and cultural norms. Contemporary theorists and empiricists emphasize on constructing knowledge with the children and families engaged in child labour and focusing on finding innovative community-led alternatives to the worst forms of child labour. Regulations, policies, and support programmes must recognize the economic contribution of working children and work towards the children's best interests. (shrink)
