Authors: Ganguly Subhadeep , Pattnaik Smaranika
Published: December 2021

L-glutamic acid is a non-essential amino acid largely used as flavor enhancer and food additive. It also has several therapeutic applications. Fermentation has gained superiority over its chemical synthesis as it produced stereo-specific isomer. Corynebacterium glutamicum is mostly used microorganism for Lglutamic acid fermentation. The study was dealing with optimization of L-glutamic acid production by immobilized mutant Corynebacterium glutamicum X680 in calcium alginate beads using response surface methodology as effective statistical tool. Among several parameters studied, pH, inoculums size, incubation time, concentration of sodium alginate, agitation and cell:alginate ration showed the most significant effect. Immobilized cells produced significantly (p<0.01) lower amount of L-glutamic acid (24.3mg/ml) compared to the production by free cells (27.6mg/ml). However, reusability of the beads minimized production cost and hence conferred benefit as far as the market economy is concerned.

BEHIND TRADE BALANCE SURPLUS IN KALIMANTAN BARAT AMIDST COVID-19 PANDEMIC
Authors: Fatmawati Fatmawati
Published: December 2021

ABSTRACTThis study aims to determine general exports/imports structure, find the commodities and their salient characteristics, and measure changes in primary commodities price during the pandemic in Kalimantan Barat. The data used is Kalimantan Barat's export and import from Statistics Indonesia over January 2019 - June 2021  through descriptive analysis method and Fisher Index unit value. The results explain that three primary export commodities are bauxite, palm oil, and rubber. Bauxite and natural rubber were shocked by the pandemic, but palm oil can still hold. The government encourages downstream activities for bauxite and palm oil to produce value-added products, while rubber pays more attention to upstream quality. The contribution of exports is relatively significant to affect economic growth with the downstream process performed by the government; tremendous added value can be seen in palm oil commodities. Imports are beneficial because they add intermediate materials to support industrial processes. The recommendation is that local governments continue intensive monitoring and evaluation of smelter construction even during the Covid-19 pandemic, concentrate on the grade of palm oil downstream for its sustainability, and improve rubber trading system and capacity building for rubber extension officers to provide adequate guidance to rubber farmers.JEL : F10, F19, F40. Keywords: trade balance, export, fisher index, downstream, descriptive statistics, covid-19. ABSTRAKPenelitian ini bertujuan untuk mengetahui gambaran umum struktur ekspor/impor; mengetahui komoditas utama dan karakteristik yang menonjol; serta mengukur perubahan harga komoditas utama selama pandemi di Kalimantan Barat. Data yang digunakan adalah data ekspor dan impor Kalimantan Barat yang dikumpulkan oleh Badan Pusat Statistik selama periode Januari 2019 - Juli 2021 dengan analisis deskriptif dan Indeks Fisher. Hasil penelitian menjelaskan bahwa neraca perdagangan masih didominasi oleh aktivitas ekspor. Tiga komoditas ekspor utama adalah bauksit, minyak sawit dan karet. Pemerintah mendorong kegiatan hilirisasi pada komoditas bauksit dan kelapa sawit untuk menghasilkan produk bernilai tambah, sementara komoditas karet justru lebih memperhatikan kualitas hulu. Kontribusi ekspor sangat mempengaruhi pertumbuhan ekonomi dengan proses hilirisasi yang dilakukan oleh pemerintah, nilai tambah yang sangat besar terlihat pada komoditas minyak sawit. Aktivitas impor juga sangat menunjang perekonomian, selama impor yang dimanfaatkan adalah bahan baku penolong untuk mendukung proses industri. Oleh karena itu disarankan untuk pemerintah daerah agar tetap melakukan pengawasan dan evaluasi secara intensif berkala terhadap progres pembangunan smelter meskipun di masa pandemi Covid-19, memperhatikan kualitas produk hilir minyak sawit agar dapat terus berkelanjutan, memperbaiki tata niaga karet serta meningkatkan kualitas penyuluh karet agar tepat sasaran dalam melakukan pembinaan kepada petani karet.

Published: December 2021

The outcomes of adhesion and ecotoxicity tests carried out on metal specimens faithfully representing the surface of real ships, including the primer and tie coat layers typically applied on ship hull prior to deposition of the antifouling paint, show the practical applicability of "AquaSun" antifouling sol-gel coatings. Newly developed AquaSun coatings share superhydrophicity (contact angle >115) and exceptionally high scratch resistance (ASTM 5B). Coupled to the ecofriendly antifouling mechanism based on continuous H2O2 formation upon exposure to solar light and foul release due to low surface energy, these results open the route to the practical utilization of these novel marine coatings.

The recent discovery of a hydrolytic enzyme, IsPETase, that can deconstruct poly(ethylene) terephthalate (PET), has sparked great interest in biocatalytic approaches to recycle plastics. Realisation of commercial utility will require the development of robust engineered enzymes that meet the demands of industrial processes. Although rationally engineered variants of PETases have been reported, enzymes that have been experimentally optimised through iterative rounds of directed evolution - the go-to method for engineering industrially useful biocatalysts – have not yet been described. Here, we report the development and implementation of an automated, high-throughput directed evolution platform for engineering polymer degrading enzymes. Evaluation of >13,000 IsPETase variants, applying catalytic activity at elevated temperatures as a primary selection pressure, afforded a HotPETase variant with 21 mutations that has a melting temperature of 82.5C and can therefore operate near or above the glass transition temperature of PET (60-70C). HotPETase can depolymerise semi-crystalline PET more rapidly than previously reported PETases and can selectively deconstruct the PET component of a laminated packaging multi-material. Structural characterisation of HotPETase reveals several interesting features that have emerged during evolution to improve thermotolerance and catalytic performance. Our study establishes laboratory evolution as a platform to engineer useful plastic degrading enzymes to underpin biocatalytic plastic recycling processes.
Hot atom chemistry: oxygen at stepped platinum surfaces
Authors: Gross Axel
Published: December 2021

It is a paradigm in chemistry that chemical reaction are mainly governed by thermodynamics. Within this assumption, reaction rates can be derived from transition state theory which requires a quasi-equilibrium between reactants and activated transition state complexes that is achieved through friction. However, to reach thermal equilibrium through friction takes some time. Here we show, based on ab initio molecular dynamics simulations of the interaction of molecular oxygen with stepped Pt surfaces, that chemical reactions in heterogeneous catalysis can occur in a non-equilibrium fashion when the excess kinetic energy upon entering the potential well of a reaction intermediate is large enough.
Aza-Yang Cyclization—Buchner Aromatic Ring Expansion: Collective Synthesis of Cycloheptatriene-containing Azetidine Lactones
Authors: Singh Manvendra , Gaskins Bryce , Johnson Daniel , Elles Christopher , Boskovic Zarko
Published: December 2021

We prepared a collection of complex cycloheptatriene-containing azetidine lactones by ap- plying two key photochemical reactions: “aza-Yang” cyclization and Buchner carbene insertion into aromatic rings. While photolysis of phenacyl amines leads to a rapid charge transfer and elimination, we found that a simple protonation of the amine enables the formation of azetidinols as single diastereomers. We provide evidence, through ultrafast spectroscopy, for the electron transfer from free amines in the excited state. Further, we characterize aza-Yang re- action by establishing the dependence of initial reaction rates on rates of photon absorption. Unanticipated change in reactivity in morpholine analogs is explained through interactions with the tosylate anion. Buchner reaction proceeds with slight preference for one diastereomer over the other, and successful reaction requires electron-donating carbene-stabilizing substituents. Overall, sixteen compounds were prepared over seven steps. Guided by an increase in structural complexity, efforts such as this one extend reach of chemists into unexplored chemical space and provide useful quantities of new compounds for studies focused on their properties.

The present study is to correlate bleeding time and clotting time with blood pressure, pulse rate and respiratory rate. A total of 30 apparently healthy, male and female students aged 18-25 years, were included in the study. Bleeding time, clotting time, blood pressure, pulse rate, respiratory rate was recorded by standard methods. Significant positive correlation was present between DBP and Pulse rate with bleeding time (P<0.05). Significant negative correlation was observed between respiratory rate with bleeding time (P<0.05). Significant negative correlation was present between clotting time and systolic and diastolic blood pressure (P<0.05). Significant positive correlation was observed between pulse rate and respiratory rate with clotting time (P<0.01). Our study observes correlations between bleeding time and clotting time and blood pressure, pulse rate and respiratory rate. We recommend further detailed studies in this area to understand in detail about the associations, to support diagnostic importance of bleeding time and clotting time.
Microencapsulation: A potential and promising approach in drug delivery system

Published: December 2021

Novel drug delivery system is a method by which drug delivered can have significant effect on its efficacy. There are several advantages of novel drug delivery system over conventional multi dose therapy, which include improved efficacy, reduced toxicity, improved patient compliance and convenience. Many efforts have been made in developing novel drug delivery system, which emphasizes on controlled and sustained release dosage forms to obtain optimum benefits. There are various approaches in delivering a therapeutic substance to the target site in a sustained controlled release fashion. One such approach is using microspheres or microcapsules. Microencapsulation is a process by which solids, liquids or gases can be enclosed in microscopic particles by forming a thin coating of wall material around substances, which protects it from external environment and control the drug release yielding capsules ranging for one micron to several hundred microns in size (1µ- 800µ). There are different microencapsulation techniques, which are used to obtain microcapsules for controlled release of drug. The morphology of microcapsules depends on the core material and deposition of coating material. Substances may be microencapsulated for the purpose of confining core material within capsule wall for specific period of time. Core materials are also encapsulated so that the core material can be gradually released (controlled release or diffusion) or when external conditions trigger the capsule walls to rupture, melt, or dissolve. Microencapsulation has found many applications in science and technology.
Electron cryo-tomography structure of axonemal doublet microtubule from Tetrahymena thermophila
Authors: Li Sam , Fernandez Jose-Jesus , Fabritius Amy S , Agard David A , Winey Mark
Published: December 2021

Doublet microtubules (DMTs) provide a scaffold for axoneme assembly in motile cilia. Aside from α/β tubulins, the DMT comprises a large number of non-tubulin proteins in the luminal wall of DMTs, collectively named the microtubule inner proteins (MIPs). We used cryoET to study axoneme DMT isolated from Tetrahymena. We present the structures of DMT at nanometer and sub-nanometer resolution. The structures confirm that MIP RIB72A/B binds to the luminal wall of DMT by multiple DM10 domains. We found FAP115, an MIP-containing multiple EF-hand domains, located at the interface of four-tubulin dimers in the lumen of A-tubule. It contacts both lateral and longitudinal tubulin interfaces and playing a critical role in DMT stability. We observed substantial structure heterogeneity in DMT in an FAP115 knockout strain, showing extensive structural defects beyond the FAP115-binding site. The defects propagate along the axoneme. Finally, by comparing DMT structures from Tetrahymena and Chlamydomonas, we have identified a number of conserved MIPs as well as MIPs that are unique to each organism. This conservation and diversity of the DMT structures might be linked to their specific functions. Our work provides structural insights essential for understanding the roles of MIPs during motile cilium assembly and function, as well as their relationships to human ciliopathies.

Alternative splicing is ubiquitous, but the mechanisms underlying its pattern of evolutionary divergence across mammalian tissues are still underexplored. Here, we investigated the cis-regulatory divergences and their relationship with tissue-dependent trans-regulation in multiple tissues of an F1 hybrid between two mouse species. Large splicing changes between tissues are highly conserved and likely reflect functional tissue-dependent regulation. In particular, micro-exons frequently exhibit this pattern with high inclusion levels in the brain. Cis-divergence of splicing appears to be largely non-adaptive. Although divergence is in general associated with higher densities of sequence variants in regulatory regions, events with high usage of the dominant isoform apparently tolerate more mutations, explaining why their exon sequences are highly conserved but their intronic splicing site flanking regions are not. Moreover, we demonstrate that non-adaptive mutations are often masked in tissues where accurate splicing likely is more important, and experimentally attribute such buffering effect to trans-regulatory splicing efficiency.

The Impact of the News Frames on Report of the 2020 Pandemic in China’s National Media
Authors: Hai Tang , Zhe Zhu , Lihong Qi
Published: December 2021

News frames is a general application of the Frame Theory in journalistic practice, and the setting of the Frame Theory in news media, to some extent, may make the news agency have more choices of the topics, more channels of the report, and more impacts on readers and audiences. It is for this reason that news media are very interested in setting up their news frame to guide their reportage. It won’t be surprised that when important affairs took place, the media set a theme for their coverage; while at the same time, audiences recognized that they are allowed to know the facts as well to evaluate the events properly. The coverage of disaster news is one of the concrete examples. However, when reading the reportage framework of the news in China, it can be seen that media would be likely to set similar frames for the focus of the report, and this potentially created complexity and difficulty in analyzing disaster news events in terms of content classification, reporting form, and news-making on effectiveness. The outbreak of the 2020 COVID-19 gathered media to work on a centralized proposal – anti-epidemic, so that textual, audio-visual contents and other forms of reporting show a diversified perspective for disaster news. This reporting from is a new challenge for Chinese news media, reflected in their practice on how Chinese government and people fought against the virus, how Chinese medical community dispatched their team to assist COVID-19 fight, and how Chinese media responded to the vilification of foreign media during that period. This paper takes three established media Hubei Daily, CCTV and China Daily as examples for an in-depth analysis.

To explore the present status of Critical thinking and its relevant factors among undergraduates.A stratified random sampling was used to select 1013 undergraduates from 7 full-time colleges in Guangdong province. They were investigated with California Critical Thinking Disposition Inventory-Chinese Version (CTDI-CV) and a Self-Compiled Personal General Information Questionnaire. ⑴ The total score of CTDI-CV was (254.16±38.80). The undergraduates in the four levels of critical thinking of comprehensive strong, relatively strong, contradictory scope and serious opposition accounted for 1.78%, 5.31%, 87.4% and 5.51% of this group, respectively. (2) Multiple stepwise linear regression showed that the total score of CTDI-CV was positively correlated with the following 10 factors such as grade, family economic status, part-time experience, the teaching method used most commonly, like reading logic books, like reading reviews or essays, father’s warmth, mother’s warmth, openness and responsibility (β=.142 to .701，all P<.05). The following 5 factors such as father’s negation, father’s overprotection, mother’s negation, mother’s overprotection and neuroticism were negatively correlated with the total score of CTDI-CV (β=-.381 to -. 616, all P < 0.05). The overall level of critical thinking among undergraduates is relatively low. College Students' critical thinking may be related to many factors such as family rearing, school education and personal characteristics.

By investigating the actuality of school and the implementation of school policies and programs, the paper deeply analyzes the existed problems in a Hong Kong school and offers optimization suggestions: strengthen the school distributive leadership construction, promote the professional development of teachers and curriculums, establish a diversified evaluation system, develop an organizational culture of democratic cooperation and improve the curriculum leadership of principals.
Introducing a Levy Scheme to Online Educational Use of Copyrighted Works
Authors: Weijie Huang
Published: December 2021

It is common for teachers to use others' copyrighted works for the purpose of teaching. The current copyright law in many nations only exempts educational use in the context of offline classroom teaching. The use of others’ copyrighted material in online teaching may still constitute copyright infringement. To protect teachers from the chilling effect of copyright infringement, to safeguard the public's freedom to obtain knowledge, and to ensure the commensurability of the profits and responsibilities of online teaching platforms, this paper proposes a levy scheme for online teaching. Under the levy scheme, teachers are free to use others’ published work for the purpose of online teaching, provided that such use does not conflict with a normal exploitation of the work and does not unreasonably prejudice the legitimate interest of the copyright owner. Online teaching platforms should remunerate the copyright owner of the work used in the platform according to the number of participants of the course that uses such work.

Authors: Leibin Lan
Published: December 2021

The protection of intangible cultural heritage is a long and arduous systematic project. It not only protects the heritage itself, but also protects its surroundings, including its historical, scientific, and emotional connotations and the elements of cultural heritage formation. In the protection of intangible cultural heritage, the local government will play a leading role and bear unshirkable responsibility for the success or failure of the construction. In the process, however, local governments are often affected by various factors, resulting in adverse phenomena such as government undertaking the whole things and protective damage. This paper takes minority areas as the research district to study the government responsibility for the protection of intangible cultural heritage.

Therefore, this research focuses on the SCF solutions applicable to e commerce enterprises of fresh agricultural products.
Decision-making under Market Indeterminacy
Authors: Yun Shi
Published: December 2021

The Efficient Markets Hypothesis (EMH) is the focusing topic in the past 50 years of financial market researches. Many empirical studies are then provided that want to test EMH but have no consensus. The perception of EMH determines the attitude and strategy of participants and regulators in financial market. One perception of EMH argues that investors’ behavior of seeking abnormal profits and arbitrage drives prices to their ‘‘correct’’ value. Investigating the “correct” value derives the concept of “market indeterminacy”. It means the inability to determine whether stock prices are efficient or inefficient. Market indeterminacy pervades stock markets because “correct” prices are unknown because of imperfect information and model sensitivity. Market indeterminacy makes arbitrage risky and makes event studies unreliable in some policy and litigation applications. The concept of market efficiency is needed to be re-recognized considering the mechanism of price formation. In order to further research and practice in law and financial market, there needs a view from the “jumping together” of disparate disciplines. Adaptive Markets Hypothesis(AMH) that using the evolutionary principles in financial market is a new viewpoint oncognitive decision and deserves to be paid more attention to.
An Analysis of the Impact of Dual Crises on Hong Kong’s Financial Development
Authors: Keyi Wang
Published: December 2021

According to the GFCI ranking from 2018-2020, Hong Kong fell from third to sixth, surpassing cities in other Asian countries and some inland cities in China. Hong Kong’s marginalization has intensified because of the impact of the new crown epidemic and anti-repair incidents. However, Hong Kong’s marginalization is indeed somewhat inappropriate. As far as the situation is concerned, Hong Kong still has a strong competitiveness, although it is lagging behind, but Hong Kong should think deeply about the strategy and system of “one country, two systems”, believe in the country’s strategic intention and adjust its state in time to re-exclude the public’s understanding of its marginalization.

Neste artigo, apresentamos os resultados de pesquisa de uma dissertação na temática da História da Educação Matemática, a qual teve por objetivo o estudo dos aspectos históricos do ensino de aritmética no contexto de Grupos Escolares, no período da pedagogia intuitiva em Mato Grosso. A abordagem metodológica considerou os tratados da operação historiográfica de Michel de Certeau, com o ensinamento dos movimentos do ofício do historiador em termos das práticas científicas para constituir uma história. O conjunto documental analisado trata das narrativas produzidas pelas instituições escolares depositadas no Arquivo Público do Mato Grosso. Muitas destas fontes foram elaboradas em relatórios por personagens históricos da instrução mato-grossense, configurados pelo representante institucional, ou seja, o diretor escolar, que desta forma nos possibilitou a análise para compreensão dos significados históricos sobre o ensino de aritmética do período em destaque. Por meio das análises, identificamos uma implementação consolidada do método intuitivo para ensinar os conteúdos disciplinares de aritmética, preconizando assim a modernização das formas de ensinar, mediante a circulação e apropriação de livros, materiais didáticos, normativas e ideias pedagógicas atreladas ao ensino intuitivo.

Background. Improvement of the technical aspects of surgery in aesthetic surgery led to an increase in the number of transactions and significant increase contingent of women who are turning to specialized clinics. But it also significantly increased the proportion of patients with a variety of concomitant diseases requiring new approaches to operational technologies and special attention in the postoperative period. In this group of patients is high risk of intraoperative and postoperative complications significantly limits the range of indications. So to prevent these complications is an important question when planning operations in aesthetic surgery of the face. Objective. Determine structural and functional changes of temporal area skin in women of different age groups with an additional internal pathology. Methods. Intraoperative biopsy material of skin of 104 women at the age from 19 to 73 years, that was taken during standard surgery instrumentations for different defects of face skin correction, was investigated. Results and conclusion. It was determined, that involutive dynamic of microvessel condition in papillary layer of derma coincides with grade reduction of relative volume of microvessels bed. Microcirculation age changes include structural disorders of intrapapillary capillary loops, disorganization of arterioles in papillary and reticular layers of derma, disorders of venules because of the changes in microenvironmental fibrillar network. It is typical at the patients with nicotinic dependence, ischemic heart disease, hypertonic disease, a diabetes, and also adiposity of a different degree essential infringement of microvessels bed structure criteria of skin condition that gives the basis for allocation of the given contingent of patients as group of high intraoperative and postoperative risk at carrying out of frontlift.

Background. Chronic myelomonocytic leukemia (CML) is rarely diagnosed and it is 1 per 100 thousand adults annually, in the United States - in 4 per million people, which is about 1100 cases per year. This disease is more common for men over 60. Results. A clinical case of a rare long-term course of myelodysplastic chronic myelomonocytic leukemia (MDCMML) in a middle-aged woman with rapid transformation into acute monocytic leukemia (AMoL-M5v) with atypical fulminant course is presented. Changes in the blood test were identified accidentally during a routine examination. A retrospective analysis of the course of the patient's disease, anamnesis made it possible to draw attention to the severe course of vasculitis of unknown etiology, with a predominant lesion of the skin of the lower limbs, which required inpatient treatment (19 years ago); skin lesions in the form of transient erythema, spotty eruptions for more than 10 years, moderate cervical lymphadenopathy. According to the WHO criteria, the morphological data of the bone marrow puncture corresponded to the MD of the CML. The long course of the disease without an obvious clinical picture, neutrophil dysplasia, myeloid proliferation was atypical, which did not exclude the presence of previous oligomonocytic CML in the patient. A detailed picture of the disease appeared after a viral infection, bronchitis, antibiotic therapy. In the absence of an increase in the number of blasts in the bone marrow, in a few of them normal Auer's sticks were detected, which, according to the literature, is a rarity in CML and an unfavorable prognostic factor of rapid transformation into acute myeloid leukemia. Conclusion. Not typical for the course of acute monocytic leukemia in this case were the absence of significant blastemia and severe suppression of normal hematopoiesis with pronounced extramedular manifestations. There was febrile fever, hyperplasia of the gums, tonsils with ulcerative-necrotic changes in the oral mucosa, an increase in cervical lymph nodes in the form of packets up to 2 cm in diameter with signs of sarcomatous growth. Attention was drawn to the progression of skin lesions, which was prognostically unfavorable. Notable was the development of severe hemorrhagic syndrome without severe thrombocytopenia, significant changes in the coagulogram, as a manifestation of early severe coagulopathy. There was a spread of erythematous elements on the skin with itching, not controlled by antihistamines and corticosteroid drugs (maculopapular rashes of a pink-cyanotic color, in places of a confluent nature, small-point hemorrhages like vasculitis over the entire surface of the skin).

Objective. To prove experimentally the effectiveness of a new generation of application sorbent by studying the morphological changes during the wound process. Methods. Depending on the drug used to treat purulent wounds, we divided the animals into three groups. In the main group (group I) the study was performed on 20 rats, they used an application sorbent, which includes aerosil with immobilization on its matrix ornidazole (Patent of Ukraine for utility model № 115228). The comparison group (group II) consisted of 10 rats, which used the known sorbent "Gentaxan", which includes: gentamicin sulfate, L-tryptophan and zinc sulfate. The comparison group (group III) was 10 rats. In this group for the treatment of purulent wounds used 10% sodium chloride solution, followed by a transition to ointment "Levomekol", which includes chloramphenicol and methyluracil. Results. The results of the study show that in the main group already on the seventh day in comparison with the comparison groups was found granulation tissue with a large number of newly formed vessels of the microcirculatory tract and pronounced proliferation of fibroblasts, indicating acceleration of wound healing. In the comparison groups, the regeneration process was slower. Conclusion. Pathomorphological examination revealed that drugs with sorption properties contribute to a faster reduction of edema and inflammation, and treatment with application sorbent used in the main group, significantly accelerates the processes of connective tissue repair and wound epithelization, ie accelerates wound healing processes with comparison groups.
