Features of trace element composition of beryl
from the Uralian Izumrudnye kopi
Authors: Gavrilchik A.K. , Skublov S.G. , Kotova E.L.
Published: October 2021

It was found as a result of SIMS study of beryl with various color zoning from the Uralian Izumrudnye Kopi that the content of a number of trace elements regularly varies to the margin of the crystal regardless of the color nature of the central and marginal crystal parts. The Na, Mn, Ga, Fe and Rb content increases towards the periphery of both crystals forming a U-shaped zoning. This pattern is less pronounced for Ni and Co. The Ti content, on the contrary, decreases towards the crystal margin forming a bell-shaped zoning. The distribution of a number of elements demonstrates another zoning pattern. For the beryl crystal (sample 24), the color saturation and transparency of which increases from a colorless to green-yellow from the center to the periphery of the crystal, the Sc, Cr and V forms U-shaped zoning with an increasing content to the margin of the crystal and Li exhibits a bell-shaped zoning. In transparent beryl crystal with more intense green color in the center (sample 25), the zoning pattern is dramatically distinct: bell-shaped for Sc, Cr and V and U-shaped for Li. The content of each element for both crystals coincides in the marginal zones, which have color comparable in intensity and transparency, despite the diferent color pattern with a sharply contrast¬ing distribution in the central part. In discriminant diagrams proposed for the identifcation of emeralds from various world regions, the composition of beryl from the Uralian Izumrudnye Kopi correspond to the feld of compositions of the Uralian emeralds or is close to them.

Thorium, uranium and rare earth mineralization in rocks
of the Ugakhan gold deposit, Bodaibo ore region (Irkutsk oblast)
Authors: Shepe E.V. l , Ayupova N.R. , Rassomakhin M.A. , Khvorov P.V.
Published: October 2021

The paper reports on the results of studies of ore-bearing rocks of the Ugakhan gold deposit (Bodaybo district): metasandstones, metasiltstones and carbonaceous shales. The rocks consist of quartz, feldspar (albite, orthoclase), Fe-Mg chlorite, mica (muscovite, sericite) and carbonates (calcite, dolomite, anker-ite) and accessory titanite, rutile, tourmaline, zircon and apatite. All rocks contain fragments of microfossils exhibiting striking concentric zonation with alternated dark (carbonaceous matter) and light (carbonate-mica material) layers. In a range from metasandstones to carbonaceous shales, the rocks exhibit an increase in mica amount and the content (up to 3%) of carbonaceous matter, as well as the formation of regeneration rims around relict tourmaline and zircon. The REE mineralization includes silicates (REE-bearing epidote, thorite), fuorocarbonates (bastnesite) and phosphates (monazite, xenotime, ankylite), which are closely related to U minerals (uraninite, cofnite). Bastnesite, ankylite and thorite formed due to the decomposition of earlier REE-bearing epidote, whereas monazite and xenotime are the products of decomposition of apatite. Uraninite formed during lithifcation of matrix of carbon-bearing rocks and is replaced by cofnite. The thermal analysis of carbonaceous matter and the formation temperature of chlorite calculated using chlorite geothermometer (296–371 °С) indicate the transformation of rocks under conditions of sericite-chlorite subfacies of greenschist facies of metamorphism.

Identification of Differences in Perception of Uncertainty Factors in the Consumer Behavior of Millennials in E-commerce
Authors: Horváth Jakub , Bačík Radovan , Fedorko Richard
Published: October 2021

E-commerce offers huge potential in terms of online sales, but also poses certain risks for consumers and retailers, in particular cybercrimes, hacker attacks, spam, but also a lack of personal interactions and information asymmetries. These risks may lead to consumer uncertainty. This means that consumers feel insecure when buying products online compared with buying the same products in brick-and-mortar stores. This uncertainty when shopping online discourages many consumers from taking part in online transactions. Previous research points to the fact that consumer uncertainty stems from perceived information asymmetries due to hidden information and moral hazard problems. Perceived information asymmetry can be defined as the situation in which the buyer thinks that the seller has a greater amount or quality of information about products, their properties, and ultimately sales practices.

Factors influencing the purchase behaviour of organic food products in the Generation Y cohort
Authors: Sharp Dr Kirsty-Lee , Synodinos Dr Costa
Published: October 2021

The modern consumer is inundated with various hazardous issues, especially concerning the environment. The increased environmental awareness has altered the way consumers think about their food purchases. Consequently, organic food products are receiving a lot more attention and consumers are opting to consume organic products over their traditional counterparts. This organic consumption change may be attributed to factors, such as environmental issues, health concerns, future preservation and natural taste. Often these organic food choices are linked to consumers that seek to change their lifestyles to be more environmentally conscious or loyal to pro-environmental causes. An organic food product has been defined in a multitude of facets, however, each definition generally retains the same core basis. In general, these products have been produced in a sustainable manner and are free from harmful agents, such as pesticides, mineral fertilisers, artificial colorants and any other harmful chemical agent. As South Africa is an emerging country in retrospect of organic food and environmentalism as a whole, South African consumers are demanding more organic products and safer sustainable business practices than ever before. The environmental movement is on the rise and businesses need to comply with this new demand should they wish to stay relevant in the ever-changing consumer market. Organic product prices are perceived as being more expensive than traditional products, this directly effects the purchase decision of a product. Increasing demand should result in decreasing prices over time, encouraging more organic product purchases. Other factors may also affect the purchase decision of organic products and these may include health consciousness, convenience, attitudes and overall purchase behaviour. This raises the question of what factors influence the South African Generation Y consumer to purchase organic products.

Charge transfer and catalytic properties of various PEDOTs as Pt-free counter electrodes for dye-sensitized solar cells
Authors: Kurokawa Yuki , Vats Ajendra Kumar , Kato Takehito , Shafie Suhaidi , Pandey Shyam S.
Published: October 2021

Despite the high electrocatalytic activity of Pt and the fact it is a champion catalyst for the counter electrode (CE) of state-of-art dye-sensitized solar cells (DSSCs), its high cost, rarity, and the concern about its possible deterioration by the iodine-based redox electrolyte, has compelled the search for suitable and low-cost catalysts for CEs. To circumvent this issue, efforts were directed to exploring the suitability of various types of poly(3,4-ethylenedioxythiophene)(PEDOT)-based conducting polymers as the most suitable electrocatalysts for low-cost CEs. Amongst various types of PEDOT explored as CEs, micelle directed electropolymerized PEDOT:SDS (:sodium dodecyl sulfate) exhibited not only excellent catalytic activity (>Pt), as confirmed by cyclic voltammetry and electrical impedance spectroscopy investigations, but also fairly good photovoltaic performance exhibiting photoconversion efficiency of 5.8%, which is only slightly lower than the performance shown by Pt-based CE for the DSSCs fabricated under similar experimental conditions. Further improvement for the PEDOT:SDS-based CE surpassing the Pt-based CE is envisioned by morphological control and making their suitable composites with carbon-based nanomaterials.

Published: October 2021

This study reports a color based texture classification for a machine vision system for the identification of disease in plants from color leaf images. We applied the texture features in literature and studied which subset will be effective for Mango and Tomato plants. Effectiveness of each statistical functions were studied in classifying the pattern using a Support Vector Machine. For textures which are different like smooth new leaves, dry leaves and growth Gray Level Co-occurrence based statistics was effective but values failed to discriminate in tomato diseases. We propose a novel method which uses second order statistics on a pseudo color based co-occurrence matrix which resulted in a better classification for three tomato diseases. This method can be applied for early Disease Detection for any plant and help farmers take corrective measures to avoid loss of yield.

In sugar industry, the sugar processing done in different sections, but to increase total crushing per day (TCD) capacity, the milling section takes a vital role in the sugar industry. The sugar industry aims to extract the maximum amount of juice from sugarcane. In the milling section, the processed sugarcane is fed in between the three-roller shaft from the different arrangements, there are different loads applied on each part roller shafts. When load between all rollers varies then there is a chance of bending it is analyzed to check the roller shaft condition. The modeling is done on roller shaft with the help of CATIA V5. After modeling, we analyze the condition of the rollers, when different stress or forces are applied to different sections of the roller shaft it analyzed with the help of Finite element method using ANSYS WORKBENCH software. We were selecting titanium alloy materials for the roller shaft to analyze the variation in results. When comparing the calculated and software-based results using Maximum Shear stress and Total deformation for top, feed, and discharge rollers said the roller shafts are safe to use in the sugar industry and titanium alloy is the best material for these roller shafts.

FEATURES OF THE ORGANIZATION OF INTERNATIONAL CARGO DELIVERY IN A DIGITAL ECONOMY
Authors: Ilienko Oksana , Katerna Olga
Published: October 2021

The relevance of the research of digital economy problems and related concepts is determined by the fact that the share of industries that rely on digital technologies is constantly growing. There are processes of penetration of digital technologies into other spheres of society, in particular, into international trade and the organization of international deliveries on the basis of digital technologies, which radically change their technological structure. Some activities have already been completely transformed under the influence of digital technologies. It is to be expected that e-commerce will soon dominate at the household level, and approaches to the organization of trade itself will change greatly. At the same time, the dynamism of the digital economy and the diversity of its manifestations are the reason why many areas of the economy and the impact of digitalization on them remain poorly understood. One of such areas is the organization of international cargo delivery. This explains the choice of the topic of scientific research, the relevance of which does not require additional argumentation, because it is obvious.

Публікація дає чітке визначення поняття «креативних та культурних індустрій», окреслює головні сфери та галузі їх реалізації в умовах сучасних глобалізаційних процесів. Історичний екскурс у часи Стародавньої Греції, а також знайомство із поглядами на сферу дозвілля античних філософів: Платона і Аристотеля, дає можливість повернутися до витоків креативних індустрій, проаналізувати їх з точки зору змістовності та сенсу як для окремої особистості, так і для людства в цілому. Автор міркує над питанням: чи лишилися актуальними античні традиції та погляди на дозвілля у наш час, чи можемо ми наразі упевнено стверджувати, що основою культури ХХІ століття є дозвілля. Розглянуто історичні аспекти появи даного явища як окремого сектору економіки. Крізь призму міркувань і загальних прогнозів провідних науковців та філософів ХХ століття висловлено думку про можливий негативний вплив масової комерціалізації культури на розвиток як окремої особистості, так і людства в цілому.

Необхідність збільшення видобутку природнього газу змусила звернути увагу на альтернативні джерела. Одним з яких є ущільнені піщано-алевритові породи, які можуть бути насичені вуглеводнями. В останні роки важливу роль при бурінні свердловини почали відводити геолого-технологічному контролю. До складу якого входить ряд досліджень, що спрямовані на виявлення кількості вуглеводнів, в тому числі в ущільнених породах.Мета даної роботи – запропонувати методичні основи оцінки ступеня вуглеводненасичення в ущільнених піщано-алевритових породах, використовуючи базові геологічні критерії, які вказують на перспективність товщі. Для впорядкованого та послідовного дослідження вуглеводненасичення в ущільнених піщано-алевритових різновидах, процес розділено на два етапи. На першому етапі відбувається оцінка перспектив нафтогазоносності ущільнених піщано-алевритових порід та виділяються ділянки з аномально підвищеною температурою. На другому – застосовується комплекс методів, спрямованих на визначення ступеня вуглеводненасичення ущільнених піщано-алевритових порід. До цього комплексу входять: геолого-технологічні, газо-геохімічні та промислово-геофізичні дослідження. Кожен з цих методів розглянутий окремо з урахуванням критеріїв перспективності, які викликані певними умовами та процесами. Запропонований комплекс досліджень дозволяє встановити ступінь вуглеводненасичення ущільнених порід на початкових етапах дослідження та при подальшому освоєнні.Методичні основи реалізовані на конкретних прикладах в межах південної прибортової зони Дніпровсько-Донецької западини. Визначення ступеня вуглеводненасичення являється ключовим процесом при дослідженні ущільненої товщі та потребує фундаментального підходу. Для оцінки ступеня вуглеводненасичення та розгляду процесу освоєння за основу взяті зони, які максимально відрізняються одна від іншої за величиною температурної аномальності. Об’єктами для дослідження прийняті Левенцівсько-Богатойська та Перещепинсько-Пролетарська зони.

У статті з’ясовано особливості розвитку науково-інноваційної діяльності та високотехнологічних промислових підприємств в умовах трансформації індустріальної сфери економіки Києва. На основі аналізу динаміки наукового потенціалу протягом 2010-2019 рр. встановлено стійку тенденцію до скорочення чисельності науковців та кількості організацій, які здійснюють наукові розробки і дослідження. З’ясовано, що ці зміни та критично низьке фінансування наукових та науково-технічних робіт, стримують розвиток високотехнологічного сектору промисловості Києва. Наслідком цього є поглиблення технологічного розриву між Україною та економічно високорозвиненими країнами світу. У статті обґрунтовано роль інноваційної діяльності промислових підприємств. З’ясовано, що незважаючи на зростання фінансування інноваційної діяльності, відбувається зменшення кількості інноваційно активних підприємств, а реалізація нових для ринку видів продукції скорочується. На основі аналізу динаміки фінансування інноваційної діяльності, джерел надходження коштів та структури витрат з’ясовано роль держави, промислових підприємств та іноземних інвестицій у розробці інновацій. Виявлено та проаналізовано особливості розвитку однієї з динамічних високотехнологічних галузей промисловості Києва – фармацевтичної. На основі проведеного дослідження визначено основні проблеми науково-інноваційної діяльності та високотехнологічних промислових підприємств, розв’язання яких сприятиме перетворенню Києва в науковий центр та осередок технологічних інновацій на європейському просторі.

Patients were debarred if they had type B fractures according to AO classication, multiple injuries, or pathological fractures and were treated more than seven days after injury. Radiographic parameters, tilt and height including radial inclination, were measured pre-and postoperatively. Results:- The radial height was 10.2 mm at the sixth month postoperatively, and the average radial tilt was 10.6° of volar. Three patients of pin tract infection were recorded. There were no cases of pin loosening. Total 73 patients underwent surgery, and three cases of radial nerve irritation were recorded at the time of cast removal. All radial nerve palsies resolved at the six-month follow-up. Conclusion:- Our modied technique is successfully restoring anatomic congruity and maintaining the reduction in fractures of the distal radius.
A RETROSPECTIVE STUDY OF RHINO-ORBITAL MUCORMYCOSIS
Authors: Srinivasan S. , Divya P. , Rohini A. , Jayapreethi R.
Published: October 2021

BACKGROUND: Mucormycosis is a rapidly progressing, life threatening, opportunistic fungal infection caused by
angioinvasive mucorales species of the phylum zygomycetes.The major risk factors of the disease are uncontrolled
diabetes mellitus, COVID-19 infection,prolonged usage of high dose of systemic corticosteroids,immunocompromised
status and neutropenia. These create a nidus for fungal infection through nasal mucosa which spreads up through
paranasal sinuses into orbit manifesting as rhino-orbital mucormycosis.
AIM
1. To study the epidemiology and various clinical patterns of presentation of rhino-orbital mucormycosis in post covid
patients.
2. To analyse the risk factors associated with progression of rhino-orbital mucormycosis in post covid patients.
METHODS: A retrospective study of 25 patients diagnosed as rhino-orbital mucormycosis in post covid patients at
Government Kilpauk Medical College Hospital between April and July 2021 was done.
RESULTS: In our study,males (64%) are more commonly affected with age preponderance of 51-60 years(28%). The
mean age of presentation was 52.1+/-4.49years.The most common symptom of the disease is nasal discharge with sinus
and orbital pain(52%).The most common form of presentation is orbital apex syndrome in seven patients(28%).Five
patients had loss of vision, of which four were due to central retinal artery occlusion(16%) and one due to cavernous
sinus thrombosis.MRI imaging of these patients showed sinus involvement(100%) in all cases ,orbital(48%) and cerebral
involvement(8%).The major risk factors responsible for progression of disease in our study are uncontrolled diabetes,
prolonged usage of high dose steroid therapy, medial wall involvement, optic nerve head involvement and artery
thrombosis.
CONCLUSION: Post covid patients presenting with nasal discharge with sinus and orbital pain symptoms need to be
diagnosed and managed properly to avoid spread of infection and fatal complications. Aggressive surgical
debridement of infected tissues helps in increasing the survival rate of the patients. Patients with risk factors need to be
closely monitored to prevent vision loss and cosmetic disfigurement surgeries.

started looming over the horizon. Early recognition, diagnosis, and prompt administration of appropriate antifungal
treatment are important for improving outcomes for patients with mucormycosis.The present study was done to evaluate
the prescribing pattern of antifungal drugs and clinical outcome in Post-covid suspected cases of Mucormycosis at
Dedicated COVID hospital.MATERIALS AND METHODS: The present observational study was done after obtaining
the Ethics committee approval from Institutional Ethics Committee (IEC), Government Medical College, Jalgaon.We
collected the data of previous treatment records, demographics, comorbidities, laboratory investigations and clinical
outcome from the case files of patients admitted with diagnosis of clinically suspected mucormycosis with history of
COVID19 infection. RESULTS: Out of the total 112 patient records, majority belonged to age group 51-60 years
comprising of 37 patients (33%).In the present study,Amphotericin B was most commonly prescribed antifungal drug
followed by posaconazole, fluconazole and itraconazole.Amongst Amphotericin B, lipid emulsion was most commonly
prescribed in 82 patients (73.2%), followed by liposomal formulation in 58 patients (51.8%). CONCLUSION: The
present study aims to provide data on prescribing trends of antifungal drugs in post-COVID clinically suspected cases of
mucormycosis,which is lacking in published Indian literature
STEPS IN THE PROCESS OF NEW DRUG DEVELOPMENT

Published: October 2021

This review determines the various stages of drug discovery, pre clinical trials and clinical trials. This process involves
the identification of chemical compound, synthesis, characterization, validation, optimization, screening and assay for
therapeutic efficacy. Once a new drug target or promising molecule has been identified the process of moving from the
science laboratory to the pre clinical to clinical trials have been discussed in this article. The main aim of this process is
identifying the chemical compound which is therapeutically useful in treating and curing the disease. The most common
steps in the development of a new drug are discovery or synthesis of a potential new drug compound or elucidation of a
new drug. Once a chemical compound has shown its therapeutic efficacy in these investigations, it will initiate the
process of drug development earlier to clinical trials. The drug development from initial idea to the market is a very
complex process which can take upto 5 to 10 years and cost of $17 billion. Due to high budget of research & development
and clinical trials drug discovery process is the most expensive. The average time taken for the drug discovery is almost
12 -15 years to develop a single new compound and enter into market
Interpretation and Further Development of the Hypnodensity Representation of Sleep Structure
Authors: Huijben Iris , Hermans Lieke WA , Rossi Allessandro C , Overeem Sebastiaan , Gilst Merel M van , van Sloun Ruud JG van
Published: October 2021

Objective: The recently-introduced hypnodensity graph provides a probability distribution over sleep stages per data window (i.e. an epoch). This work explored whether this representation reveals continuities that can only be attributed to intra-and inter-rater disagreement of expert scorings, or also to co-occurrence of sleep stage-dependent features within one epoch.

Approach: We proposed a simplified model for time series like the ones measured during sleep, and a second model to describe the annotation process by an expert. Generating data according to these models, enabled controlled experiments to investigate the interpretation of the hypnodensity graph. Moreover, the influence of both the supervised training strategy, and the used softmax non-linearity were investigated. Polysomnography recordings of 96 health sleepers (of which 11 were used as independent test set), were subsequently used to transfer conclusions to real data.

Main results: A hypnodensity graph, predicted by a

supervised neural classifier, represents the probability with which the sleep expert(s) assigned a label to an epoch. It thus reflects annotator behavior, and is thereby only indirectly linked to the ratio of sleep stage-dependent features in the epoch. Unsupervised training was shown to result in hypnodensity graph that were slightly less dependent on this annotation process, resulting in, on average, higher-entropy distributions over sleep stages (Hunsupervised = 0.41 vs Hsupervised = 0.29). Moreover, pre-softmax predictions were, for both training strategies, found to better reflect the ratio of sleep stage-dependent characteristics in an epoch, as compared to the postsoftmax counterparts (i.e. the hypnodensity graph). In real data, this was observed from the linear relation between pre-softmax N3 predictions and the amount of delta power.

Significance: This study provides insights in, and proposes new, representations of sleep that may enhance our comprehension about sleep and sleep disorders.
The essence of light
Authors: Zheng shengming Physicist
Published: October 2021

In the process of exploring the essence of light, Newton initially agreed with the particle interpretation of light while Huygens argued for the wave theory. Hence, these two theories had been disputed in Newton's time. In the beginning people accepted the particle theory, but after Thomas Young's experiment and Augustin Jean Fresnel's experiment, people began to accept the wave theory. Until Einstein proposed the quanta concept, which was later called photon, and, even later, De Broglie proposed the wave nature of matter, subsequently, people began using particle-wave duality to explicate all phenomena in micro world. Thus here appears a paradox: how can one particle exist in two forms? To solve this enigma, I have done some experiments; discover that moving photons create force; this effect reveal the phenomenon of light wave property - the inference fringes is caused by force which moving photons produced. The essence of light is particle but not particle-wave duality.

Published: October 2021

Background: Antimicrobial resistance (AMR) represents a significant global public health crisis. Despite ample availability of Gram-positive antibiotics, there is a distinct lack of agents against Gram-negative pathogens, including carbapenem-resistant Enterobacterales, which remains a real threat in Japan. The AMR Action Plans aim to mitigate the growing public health concern posed by AMR.

Objective: This study aims to estimate the clinical and economic outcomes of drug-resistant Gram-negative pathogens forecasts for Japan to guide resource allocation defined within the upcoming National AMR Action Plan.

Methods: A previously published and validated dynamic health economic model was adapted to the Japanese setting. The model used a 10-year time horizon with a willingness-to-pay threshold of ¥5 000 000 (US $46 827) and discounting was applied at a rate of 2% to costs and benefits. Clinical and economic outcomes were assessed as a function of varying AMR levels of three Gram-negative pathogens in Japan by up to 100% of the current level.

Results: Reducing drug-resistant Gram-negative pathogens in Japan has the potential to save 4 249 096 life years, corresponding to 3 602 311 quality-adjusted life years. The associated maximum clinical and economic gains were estimated at up to 4 422 284 bed days saved, up to 3 645 480 defined daily doses of antibiotics avoided, up to ¥117.6 billion (US $1.1 billion) saved in hospitalization costs, and a net monetary benefit of up to ¥18.1 trillion (US $169.8 billion).

Discussion: Learnings from this study can be used by the Japanese government to help inform decision-making on the strategies that may be included in the upcoming National AMR Action Plan and facilitate allocation of the required budget.

Conclusions: This analysis demonstrated the considerable economic and clinical value of reducing AMR levels of three Gram-negative pathogens in Japan and could be utilized to support the valuation of antimicrobial treatment and resistance in Japan and more broadly.

Object: The purpose of this study was to evaluate the efficacy of ventricular shunting in normal pressure hydrocephalus (NPH).

Methods: The authors retrospectively studied outcomes in NPH patients in whom shunts were implanted. At follow-up examinations up to one year, clinical symptoms were recorded according to a new NPH outcome rating scale, the modified Rankin score and the Mini-Mental State Examination. Comorbidities and complications during this period were also analyzed.

Results: A total of 55 patients with NPH were included, with a male predominance (69% of men), an average age of 70 years. Comorbidities are multiple, hypertension is the most common factor in 55% of cases. 76% of patients are classified as having idiopathic NPH. The CSF tap test allows the evacuation of at least 40 ml of CSF and RCSF measurements in 55 patients. All these patients received a shunt withe programmable valve. An improvement in gait was observed in 88% of patients, 91% in balance and 84% in continence. The improvement in the field of neuropsychology is 34% after one year of shunt. 87% of patients were improved according to mRS. 27% of patients had complications and were treated conservatively or surgically.

Conclusions: Ventricular shunt implantation is a safe procedure and can improve symptoms in 98% of patients with NPH in the medium term.
