Published: July 2022

COVID-19, a pandemic caused by severe acute respiratory syndrome  (SARS) corona virus-2 has been a worldwide challenge for the entire mankind. However, a safe and efficacious vaccine would be clinically valuable to reduce the risks of COVID-19. In this study, we aimed to assess the seroprevalence of the Neutralizing IgG Antibodies six months after completion of both the doses of Covishield Vaccination (ChAdox1 nCoV-19) and compare it with the IgG titres one month after the first dose and one month after the second dose of the vaccine respectively. The efficacy, safety and comorbidities related to the vaccine were also assessed at different time intervals. The levels of IgG antibodies were estimated in 72 subjects from the Teerthanker Mahaveer Medical College & Research Centre (who turned up after six months of the complete regimen of Covishield Vaccination) using the Enzyme-Linked Immunosorbent Assay (ELISA) Technique. A highly significant increase (p= 0.00) in the neutralizing Antibodies titre was seen in fully vaccinated individuals post six months when compared to the titres of post one month of 1st & 2nddoses. It can therefore be concluded that (ChAdox1 nCoV-19) Covishield Vaccination if administered in full regimen has both acceptable efficacies as well as safety profile.

Published: July 2022

Background: Hypoalbuminemia has been established indicator of nutritional status, which may and may not be clinically apparent, but is linked to a significantly higher risk of morbidity and mortality. Objective: To assess the post-operative morbidity with relation to pre-operative albumin status in patients undergoing emergency abdominal surgery. Methods: It was a hospital based observational study, 100 patients undergoing emergency abdominal surgery at Tertiary care Hospital was included. Hypoalbuminemia was diagnosed if serum albumin level was less than 3.5 gm/dl. Study period was between May 2021 to April 2022. The Statistical software namely SPSS 11.0 and Systat 8.0 were used for the analysis. Results: Pre-operatively, 60 patients had hypoalbuminemia (serum albumin <3.5 g/dl) and 40 patients had normal albumin levels (≥3.5 g/dl). Out of 100 patients, 41 (41%) developed complications postoperatively. 32 patients (50%) out of 60 patients with hypoalbuminemia (with serum albumin<3.5 g/dl) had complications. 9 patients (17.5%) with albumin level ≥3.5 g/dl had complications. Mean length of hospital stay was found to be higher i.e. 9.70±4.75 days in patients with hypoalbuminemia, compared to 6.45±3.31 days with those having albumin level ≥3.5 g/dl. Conclusions: Preoperative albumin is a useful low-cost prognostic predictor for predicting surgery outcome.
Comparative Research on Confirming Labor Relation in the Platform Economy Between China and America
Authors: Peng Lixuan
Published: July 2022

With the prosperity of the platform economy, assorted new forms of businesses have emerged, which are seemingly different from traditional employees, have literally emerged. In addition, Chinese labor laws split workers into laborers and non-laborers, only when a worker is a laborer can he or she be governed by labor laws. Thus, whether such workers are laborers has caused a definitional maze in both judicial practice and academia. One of the most representative of new business patterns is the rider of the food delivery platform. This article takes the food delivery rider who best represents one of the new forms of employment as a theme for analysis, and adopts the method of case analysis and comparative research. This paper holds the view that online platform enterprises have the following essential characteristics: online platform enterprises tend to abandon their fixed assets; they take more control of riders with the blessing of algorithms; and they skirt the law to mask real legal relationships. These features all contribute to proving more difficult to determine whether a rider is a laborer. In response to the policy of building harmonious labor relations and to protect riders’ rights they deserve, this essay studies the ABC test established by the California State Supreme Court, by discussing the backdrop and merits of the ABC test, together with the reasons why it can be used for reference, to provide threads for China’s judicial practice.

Research on the Adjustment of Patent Protection Standards under Emergencies: Based on the TRIPs Agreement
Authors: Chai Yihang
Published: July 2022

The patent system has a catalytic effect on innovation and imports, which could go some way to alleviating the current vaccine dilemma in the pandemic environment, i.e. insufficient capacity and inequitable distribution. This paper identifies this role through a review of the patent system and the TRIPs Agreement and argues that countries have the flexibility to adapt their patent systems to the current situation through the flexibility provisions of the TRIPs Agreement to maximize this facilitative role in addressing the vaccine issue. This paper suggests that in the current pandemic environment it is necessary to stimulate pharmaceutical companies to accelerate the process of vaccine development by reducing the inventive step testing requirements. In addition, to reduce market risk and maximize the extent to which patents can facilitate the vaccine development process, this paper argues that flexibility should not be used as an excuse for adjusting the duration of protection and requiring a complete patent waiver.

Authors: Li Jing , Qin Yidan
Published: July 2022

As the "father of modern painting", Cézanne's creative ideas and techniques have had a profound influence on subsequent generations of artists. To this day, many artists still admire his creative and revolutionary painting theories. The purpose of this paper is to analyze the techniques and ideas of Cézanne's series of paintings around the Mount Sainte-Victoire and to explore his inspiration for subsequent artists to break through the constraints of traditional painting techniques and creatively express their subjective consciousness by using flat shapes, multi-point perspective, and multiple painting types. In this way, we can clarify the position of Cézanne in art history and the inspiration his ideas and works have brought to people. This paper is divided into two parts, the first part is about the analysis of the concept, technique and style of Cézanne's landscapes with the Mount Sainte-Victoire as the theme; the second part is about the specific distinction and explanation of the succession and development of Cézanne's style by modern artists represented by Picasso, Matisse and Klimt.
Differences in Renoir’s paintings after his trip from 1881 to 1883: the human body, color and compositions
Authors: Yue Xinyi
Published: July 2022

After the tour from 1881 to 1883, the French Impressionist painter Renoir changed his painting style dramatically, blending Impressionism's decorative and inventive effects with Renaissance-style figures and compositional skills to create a more solid and mature style of personal uniqueness. Although there have been prior studies of Renoir's itinerary and letters on route to this trip, as well as independent assessments of some of his works created after the trip, there are still relatively few reviews of the trip's general influences, therefore this study tries to fill in the gaps. Based on the contents of Renoir's travels and visits, this paper will examine the impact of Renoir's trip on the human body, color, and composition by comparing his paintings completed before and after the trip, particularly the Ball du Moulin de la Galette, Les Baigneuses, and the Umbrella.

Authors: Dou Xian
Published: July 2022

This paper selects A-share listed companies in Shanghai and Shenzhen from 2015 to 2019 as research samples, explores the relationship between debt financing, social responsibility and corporate performance from two aspects of theoretical analysis and empirical hypothesis, and uses empirical methods to verify the moderating effect of corporate social responsibility on debt financing and corporate performance. The results show that: first, debt financing is negatively correlated with corporate performance; Secondly, enterprises that actively undertake social responsibility have lower debt financing capital, and assume social responsibility plays a significant moderating role between debt financing and enterprise performance. Thirdly, corporate social responsibility is negatively related to debt financing. Corporate active social responsibility can promote the reduction of debt ratio and the improvement of corporate performance. Based on the above research results, the following suggestions are put forward: first, enterprises should strengthen the use of funds and actively assume social responsibilities; Second, government departments should strengthen policy incentives for enterprises to bear social responsibility; Third, government departments push enterprises to increase their direct financing capacity.

Published: July 2022

Physical energy storage is a technology that uses physical methods to achieve energy storage with high research value. This paper focuses on three types of physical energy storage systems: pumped hydro energy storage (PHES), compressed air energy storage (CAES), and flywheel energy storage system (FESS), and summarizes the advantages and disadvantages of each technology by collecting and evaluating the principles, components and technical parameters. In addition, this paper presents the practical applications of the technologies and finally provides an outlook on future developments. The results show that PHES technology is the most mature and has the advantages of high efficiency and long lifetime, but the current application is rather single and can be developed in the direction of variable speed/underground/seawater pumped storage in the future; CAES has larger energy capacity and longer service life, outstanding peak regulation capability, and can manage energy as well as provide power for vehicles, but its efficiency and energy density are low and need further optimization in the future; FESS has the advantages of short response time and power density, and minimal environmental effects, but currently it is mostly used for small-scale occasions and military purposes due to its small capacity, and its self-discharge rate is large, and it is being developed in the direction of increasing capacity and improving safety in the future. This paper aims to provide a systematic summary of the progress of physical energy storage technology, so as to provide information to support further research on physical energy storage.

The increasing demands of renewable energy lead to upgrading and iterating on current centralized grid system. Depends on the unique characteristics of green energies, such as photovoltaic power, wind power and so forth, the wide range of geographical allocation, power uncertainty and near to end-users has become the crucial consideration factors for next era energy system. Distributed energy system (DES) as a new emerging energy management method, it shows large numbers of similarities with renewable energy and it has been deemed as a potential reasonable way to solve the above issues. In order to illustrate whether DES have the ability to provide citizen with a sustainable, reliable and efficient grid system, this paper try to evaluate it from DES applications in different scopes and possible supportive energy internet technologies. Through discussing DES in regional and community scale, the physical limitations have been pointed out. Furthermore, micro-grid, blockchain technology and Virtual Power Plant (VPP) has been elected as potential methods to solve DES existing problems, such as data loads, inter communications between energy provider and consumer and energy trading mechanism. Since DES could not reach the optimal working status without other technologies support, how to integrate and combine different new emerging technologies into this energy system could be a further research direction. This significance of this paper is evaluating possibility of creating an autonomous, reliable, highly efficient and tradable energy system based on DES.

Authors: Wang Baoqian , Li Shuran
Published: July 2022

C4 olefins and ethanol are essential chemical raw materials, and efficiently preparing them is a valuable topic. In this paper, in order to explore the influence of different catalyst combinations and temperatures on ethanol conversion and C4 olefin selectivity, firstly, for each catalyst combination, by observing the scatter diagram of ethanol conversion, C4 olefin selectivity and temperature, a polynomial regression model of no more than three times was established. Then, 42 regression equations corresponding to 21 catalyst groups were obtained. Twenty-one kinds of catalyst combinations were grouped by controlling variables. After grouping, the relationship between a single factor and temperature was discussed. Non-interactive two-way ANOVA judged the significance of a single factor, and the control variables among different groups were compared to determine the strong significant factors of ethanol conversion rate and C4 olefin selectivity. For judging the significance of temperature, the input rate of ethanol is ignored based on grouping, and the same catalyst combination is regarded as a repeated test. By single factor analysis, it is finally found that the temperature has higher significance to ethanol conversion rate and 400℃, while the selectivity to C4 olefins is much lower.
Comparative analysis of photoelectrocatalysis and photovoltaic-electrocatalysis and their applications
Authors: Fu Junming
Published: July 2022

With the industrial development of mankind, large amounts of greenhouse gases are being released into the atmosphere, far beyond the limits of what the earth’s ecological cycle can handle. In order to reduce carbon emissions, it needs to find zero-carbon energy technologies to replace existing fossil fuel technologies, in which photoelectrocatalysis (PEC) systems and photovoltaic-electrocatalysis (PV-EC) systems are the backbone of zero-carbon photovoltaic technologies. PV-EC systems and PV-EC systems share the common essence of converting solar energy into hydrogen, but the difference between PV-EC and PEC is that PV-EC can also provide electricity while producing hydrogen, which is an additional energy output option. However, the difference between PV-EC and PEC is that PV-EC can produce hydrogen and provide electricity at the same time, providing an additional energy output option than PEC systems. This research briefly discusses the mechanics and economics of the two systems and analyses the development trends of PV-EC systems in recent years. The author suggests that PV-EC systems take advantage of the diversity and modularity of energy output, break the limits of the earth’s high-quality light source areas through energy conversion, and deploy PV-EC systems in a distributed manner to increase the efficiency of power generation and hydrogen production.

Contemporarily, whether quantum computing performs better than conventional computers remain an unresolved issue. In this paper, we compare the time complexity between quantum and conventional computers for a specific type of issue. Theoretically, quantum computation is better in solving nonlinear calculations, the quantitative evaluation of the computing ability should be investigated. In this paper, the Fourier transform was applied in both classical and quantum logical circuits to calculate the theoretical time complexities respectively and make a comparison after that. According to the analysis, the ideal quantum computer performed really fast as the number of tasks increased, but the gate-level accurate quantum circuit, which was a simulated circuit was running slower. The paper shows that the current technology cannot perform the perfect quantum computer, but the future of it would be very promising. Overall, these results shed light on guiding further exploration of quantum computing.

Authors: Wang Qiaochu
Published: July 2022

Dark matter is likely to be the main component of the universe, but it doesn’t belong to any part of known substances, which make up the visible celestial bodies. Although dark matter has not been observed directly, there is a large quantity of evidence showing that dark matter does exist. This paper showed several typical candidates and evidence for dark matter and analysed their limitations, including WIMPs, axion, and PBHs. With respect to detection method, Migdal’s effect is used as an example for direct detection and MAGIC telescope for indirect detection. For the observation evidence, the rotation curves, galaxy clusters, and cosmic microwave background are chosen as evidence. According to the analysis, though no dark matter has been already searched till now, it is believed that some promising candidates, (e.g., primordial black holes) exist in the universe. These results shed light on the future research for the property and formation mechanism for dark matter.

Desublimare il sublime kantiano? Alcune considerazioni a partire da Lyotard e Deleuze lettori dell'Analitica del sublime
Authors: Campo Alessandra
Published: July 2022

This paper aims to desublimate the Kantian sublime starting with the mitigation of the enthusiasm with which some French philosophers have woven its praise. Contrary to what Lyotard and Deleuze argue in their works, in the Analytics of the Sublime Kant does not go beyond himself, nor it is hard to set up a philosophy of the subject after reading these pages. Sublime, for these two clever readers of Kant, is any excessive use of the faculties. But Kant is less interested in excess than in its regulation. Thus, while harmonising with other 80-90s French readings of the Kantian sublime, the faith placed by Lyotard and Deleuze in its potentialities seems unfounded. It is fuelled by a lack of consideration of what happens in the second stage of this complex feeling. Unlike the encounter with the moral law introduced as a ‘fact of reason’ in the Critique of Practical Reason, in the Analytic of the Sublime reason makes itself heard not at the expense of the ego but in support of it. And the ego thus elevated is not only an ego ‘super’. It is a (Freudian) super-ego.

Bert Laeyendecker als maatschappijcriticus
Authors: Noordegraaf Herman
Published: July 2022

In the first stage of his scholarly career Bert Laeyendecker was involved in sociology of religion and church. However from the seventies he also directed himself towards a critical study of society. In this article his main writings in this field are described and analysed. In these writings he focused himself on a macro-sociological analysis of modernisation and modernity. He used two methodological approaches, a historical sociological approach that was strongly influenced by Max Weber and an analysis that was rooted in the social system approach of Niklas Luhmann. According to Luhmann, modernisation and modernity are characterized by differentiation of segments of society such as science, economy and technology. These subsystems got a dynamic with their own orientation and goals. This complex of differentiated subsystems has made an improvement of life in Western society possible, but has a one-sidedness that causes problems like destruction of environment and social inequality. For that reason a fundamental adjustment is necessary. However, that dynamic can hardly be influenced because systems for a great part have a life of their own. Laeyendecker was pessimistic about the possibilities of fundamental changes, but because of the calling for human responsibility humanity has a task to try to accomplish as much as possible. In the course of the article Laeyendeckers view on the sense of utopian thinking, on postmodernity and on the position of university and churches are dealt with.
