under Catalyst and Solvent-Free Conditions
Authors: Banerjee Subhash , Patel Ashok Raj , Patel Geetika , Das Sajal , Sharma Bhaskar
Published: July 2022

Background:

Green and sustainable method for the oxidation of aldehydes into acids is
now in demand as carboxylic acids are important and versatile intermediates. In this context, visible
LED light-promoted aerial oxidation can be efficient and greener protocol.

Objective:

Herein, we have demonstrated a visible LED light-promoted efficient and greener protocol
for the aerial oxidation of aromatic aldehydes into corresponding acids in the absence of any additives,
base, catalyst, and oxidant.

Methods:

The oxidation of aromatic aldehydes was irradiated by an LED light at room temperature
under an open atmosphere, monitored by TLC. The rate of oxidation was also monitored using different
LED lights by UV-Vis studies. The products were purified by column chromatography using silica
gel, and the mixture of ethyl acetate/petroleum ether as an eluting solvent and the pure products were
confirmed by their melting point determination and NMR spectroscopic analysis.

Results:

The aldehydes were successfully converted into corresponding acids with good isolated
yields (60-90 %) by this protocol, where blue LED light (l ~ 490 nm) was found to be the best choice.

Conclusion:

The present protocol of aerial oxidation of aromatic aldehydes into corresponding acids
under visible LED light has been carried out in the absence of catalyst, oxidant, base, and any other
additives. The higher isolated yields, no byproduct formation, and neat reaction conditions are the major
advantages of the protocol.

Published: July 2022

Older people fall at least once a year, resulting in many devastating complications that affect the older person and the carers. Many carers are concerned that the older person will fall. Three hundred ninety carers of an older person participate in this study. The study found that the carers have a high level of fall concern. The level of concern was significantly associated with the demographic variables of the older person and the level of depression, stress, anxiety, and strain. Hence, there is a dire need for a fall prevention programme and educational program for the carers.

Authors: Zahari Zarina , Abd Rahim Muhammad Faizal , Justine Maria , Sulfandi
Published: July 2022

This study aimed to identify the existing environmental hazards and their association with falls among the elderly with LBP. A cross-sectional study involving 284 participants was conducted using Fall Risk Assessment Tools (FRAT), and Home Falls and Accident Screening Tools (HOME FAST). There were 234 respondents included for analysis. Most hazards reported no slip-resistant mats in the bathroom (73.5%). There was no association between environmental hazards and falls among the elderly (p > 0.05). Environmental factors are the indecisive cause of most falls in the institutions, but their interaction with the physical abilities of the elderly could contribute to falls.

Published: July 2022

Aim: The aim of this study was to clarify the usefulness of the Liver Imaging Reporting and Data System (LI-RADS) for predicting a patient’s prognosis after transcatheter arterial chemoembolization (TACE) combined with radiofrequency ablation (TACE-RFA) for hepatocellular carcinoma (HCC) of Barcelona-Clinic Liver Cancer (BCLC) stage 0 or A. Patients and Methods: We retrospectively analyzed cases of patients with HCC who underwent TACE-RFA (Jan 2005 to Dec 2015). Nodules were categorized based on their LI-RADS v2018 core. The LI-RADS category was assigned to each nodule using dynamic contrast-enhanced computed tomography. LR-3, LR-4 and LR-5 nodules were extracted. The overall (OS) and recurrence-free (RFS) survival was assessed among patients with BCLC 0 and BCLC A disease. Results: Of the 64 nodules extracted, 22 were LR-3 or -4 (mean±standard deviation=14.8±6.7 mm) and 42 were LR-5 (17.1±6.9 mm). Regarding OS, there was no significant difference between those with LR-3 or -4 and LR-5 (p=0.278). In terms of RFS, there was a significant difference between those with LR-3 or -4 and those with LR-5 (p=0.03). In particular, patients with BCLC A with LR-5 nodules had significantly poorer RFS than those with LR-3 or -4 (p=0.016) nodules. Conclusion: For patients with BCLC A, LR-3 or -4 nodules are associated with a better prognosis than LR-5 nodules.

Background/Aim: Although acute myeloid leukemia (AML) has traditionally been considered an oncological emergency and initiation of therapy is believed to be crucial to minimizing disease-related morbidity and mortality, it has also been suggested that a certain delay in treatment has no negative consequences in terms of response, early mortality, or survival. We aimed to determine the effect of administration of sodium caseinate (SC), a salt of casein, the main milk protein, with cytarabine or with daunorubicin on survival in mice with well-established leukemia. Materials and Methods: To assay the time of establishment of leukemia in the bone marrow, Balb/c mice were inoculated with 2.5×105 WEHI-3 cells/mouse and after 3, 6 and 9 days were euthanized. Bone marrow mononuclear cells (BM-MNCs) of the femur were obtained and cultured for 120 h with or without rmIL-3 and cell proliferation was evaluated by the crystal violet technique. Then, the effect of administrating SC-cytarabine or SC-daunorubicin on survival rates of mice with well-established leukemia was assayed. Another group of Balb/c mice was inoculated with WEHI-3 cell and after 10 days mice were treated with SC-cytarabine or SC-daunorubicin for 40 days. Survival rates were recorded daily and in surviving mice, the prevalence of bone marrow proliferation after treatment was assayed by the crystal violet technique. Results: The assay on the time of establishment of leukemia shows that in 9 days leukemia cells accumulate in the bone marrow in sufficient quantities to sustain an in vitro culture in the absence of growth factors, and we, thus, used this as a criterion of well-established leukemia. When mice with a burden of leukemic cells of more than 9 days were treated with SC-cytarabine or SC-daunorubicin, this resulted in 55% survival for both treatments, and the proliferation assays showed that the bone marrow retained its normal proliferation capacity. Conclusion: SC-cytarabine or SC-daunorubicin treatment prolonged the survival rate of Balb/c mice with a burden of well-established leukemia, and there was no negative impact on bone marrow functionality; however, SC-cytarabine or SC-daunorubicin combination options need to be sought to increase survival beyond 40 days.
Understanding Mental Health Apps for Youth: A Focus Group Study with Latinx Youth (Preprint)
Authors: Agapie Elena , Chang Katherine , Patrachari Sneha , Neary Martha , Schueller Stephen M.
Published: July 2022

BACKGROUND

An increasing number of mental health apps (MHapps) are being developed that focus on youth. Additionally, youth report being high users of technologies generally and MHapps specifically. Little is known, however, about youth’s perspectives on MHapps and methods to better involve youth in the process of providing feedback on apps.

OBJECTIVE

The goal of this study was to develop a process for eliciting youth perspectives on MHapps in a structured and collaborative way. We also sought to identify early learnings on aspects of MHapps and youths’ use of them that might facilitate discovery, activation, or engagement in MHapps.

METHODS

We created a series of five focus groups sessions that would introduce youth to different categories of MHapps (cognitive behavior therapy apps, mindfulness apps, miscellaneous). Within each category, we select four MHapps and participants would choose one to use for the week and provide feedback through both between-session and in-session activities. At the end of completing all five of the focus groups, participants completed a brief questionnaire to gather their impressions of the apps they had used.

RESULTS

We identified several aspects regarding MHapps that were important to youth. Youth wanted apps that were youth-centric, simple, could integrate with their offline lives, and also were relatable and accessible. We also found that the mindfulness apps we assigned to youth were viewed most favorably but that cognitive-behavioral therapy apps were viewed as more impactful.

CONCLUSIONS

Eliciting youth feedback on MHapps is critical if these apps are going to serve a role in supporting their mental health and wellbeing. We identified factors that were important to youth and refined a process for collecting feedback. Future work could go broader, i.e., recruiting larger samples of more diverse youth, or deeper, i.e., collecting more information from each youth around interests, needs, barriers, or facilitators or better understanding the various impacts of MHapps using qualitative and quantitative measures. Nevertheless, this study advances formative understanding of how youth might be viewing these tools.

Physical and Mathematical Model of Relaxation Filtration of Undergrounds Water
Authors: Burakov Mikhail M.
Published: July 2022

Earlier, a number of publications presented the results of an experimental study of the free oscillations of the piezometric level of groundwater (pressure in a liquid) in wells with natural frequencies. In this case, the oscillations were initiated by a pulsed action on the aquifer through disturbing wells. The same publications proposed a theoretical interpretation of the established phenomenon. However, a critical analysis of these theoretical constructions showed their incorrectness. Accordingly, a consistent physical and mathematical model of groundwater relaxation filtration is proposed in this work, which provides a theoretical basis for the description and interpretation of the free oscillations of the piezometric level in a disturbing well with natural frequencies. Thus, the proposed physical and mathematical model made it possible to conclude that it is impossible to cause resonance during the initiation of free oscillations of the piezometric groundwater level. An analysis of the experimental data based on the model showed that the implementation of methodological developments based on the theory of relaxation filtration is possible and expedient only on fundamentally different, in comparison with existing, technical and methodological approaches to the experimental study of wave propagation in aquifers.

Gamma Radiation (137Cs) for the Treatment Against Resistant Fungi in Two Brazilian Libraries
Authors: Costa Antonio Carlos Augusto da , Arbach Mayara Nascimento , Ferreira Ana Cristina de Melo , Lutterbach Márcia Teresa Soares , Oliveira Ana Lucia Chaves de
Published: July 2022

The present work showed that a wide diversity of fungi was found in the environment where the Collection Academia Brasileira de Ciências is stored, in the Henrique Morize Library, being this diversity quite common in spaces storing this kind of cellulosic material. Fungal genera such as Aspergillus, Cladosporium, Rhizopus and Trichoderma were identified through modern Molecular Biology techniques. The presence of these fungal genera is probably associated to climatization and humidity control, which prevent the occurrence of a wider diversity of microbes. However, two fungal genera, Trichoderma and Rhizopus, resisted 137Cs irradiation doses with up to 19 kGy, considered high for the elimination of fungi. On the other hand, in the National Library, particularly in some sectors, an even higher diversity of fungal species/genera was observed, a fact that seems to be compatible with the size of the library, with a much higher circulation of people. This higher microbial diversity indicated the occurrence of fungal species absolutely uncommon for in libraries and archives, such as: Diaphorte, Trametes, Arxotrichum, Grammothele, Pessiophora, Phebia and Talaromyces. Just successive samplings in the same areas will allow a confirmation if these fungal genera are permanent of occasional, due to some oscillation in the operation of circulation systems or a possible transport of these species from the outside to the library, which allows those species to remain latent in relation to growth. All microbial samples from the National Library, survived irradiation up to 16kGy.

The study aimed to investigate, through the literature, the historical evolution and perspectives of the humanization process of care during childbirth. This is a bibliographic research, in which two databases were searched, namely: SciELO and LILACS, with national publications in the last 10 years. Fourteen scientific articles were analyzed using articles published in Portuguese as inclusion criteria; full articles and articles published and indexed in the aforementioned databases in the period from 2012 to 2022. As a result, it became evident that the humanization of childbirth is very current and still occurs as a reaction to several procedures performed without indication, requiring efforts to all the subjects involved, seeking to guarantee the woman quality and comprehensive care, which requires from all the actors involved with health care efforts to abolish aggressive behavior. It was concluded that the movement for the humanization of childbirth shows that the issue of birth is also the responsibility of the government and, given the current problems such as those related to the infrastructure weaknesses of the health network in Brazil, it is also configured as a health issue public.

Published: July 2022

Abstract: Online real estate Registration is a project which provides a friendly format to register land properties. Users can search and browse for property in this application. This application also allows users to see land details on online. This application mainly concentrates on maintaining and managing the details of the property. This application deals with lands details. Now-a-days all applications which require huge security are migrating their application to Block chain as Block chain inbuilt for security data. All existing techniques were not having any facility to check whether data store at decentralized (same data will be saved at multiple nodes and if one node hack or down then data will be gather from other working node) server is intact or change. To check data is intact we can use Block chain technology to maintain land registration details as this technology maintain tree to store each transaction (any data storage will be consider as transaction) and while storing new data then Block chain verify all transaction hash code and if data is not alter or hack then same hash code will be generated and verification will be successful and new block will be added and if data is changed then different hash code will be generate and verification will be failed which indicate node is hack.
Study on Dynamic analysis of Grid Interactive of offshore wind and Marine Current Farm
Authors: Valecha Mr. Mohit
Published: July 2022

Abstract:-In day-to-day life due to growth of power demand worldwide. The use of conventional energy is increased and there is reduction in conventional resources. To fulfill the Demand, it is essential to increase the renewable resources like wind, tidal, solar etc. The energy which is sustainable means which is endless. The ocean has untapped energy resources in the form of tidal wave, geothermal, offshore wind etc. at different geographical locations.OWF combined with MCF, owing to their natural availability in close proximity, would become a new kind of integrated energy generation system in near future. Mainly there are TWO types of generators synchronous and asynchronous generator we use asynchronous generator because wind is not constant in offshore wind farm .There are FOUR types of generators used in offshore wind farm (OWF) which are named as:- Doubly fed induction generator (DFIG), Squirrel cage induction generator(SCIG) ,Wound-Rotor induction generator(WRIG) ,Permanent Magnet Synchronous generator (PMSG). And in our project, we have taken wind Energy as a source and our system is hybrid of offshore wind and marine-current farm connected to an onshore power grid via a high-voltage alternating current (HVAC) link. The performance of the studied offshore wind farm (OWF) is simulated by a doubly-fed induction generator (DFIG). DFIG system is a popular system in which the power electronic interface controls the rotor current to achieve the variable speed necessary for maximum energy capture in variable winds .while the operating characteristics of the studied marine current farm (MCF) are simulated by a squirrel-cage induction generator (SCIG).SCIG is attached to the wind turbine by means of a gearbox. The wind turbine is responsible for transforming wind power into kinetic energy .Both frequencydomain approach based on a linearized system model using Eigen value analysis and time-domain scheme based on a nonlinear system model subject to a disturbance condition are carried out. It can be concluded from the simulated steady-stated transient results that the proposed HVAC link can effectively stabilize the hybrid OWF and MCF under various disturbance conditions

Recognize Candidate task for Robotics Process Automation
Authors: Kushwaha Sunil
Published: July 2022

Abstract: Innovation is progressing quickly in practically every one of the fields, not in a moment but rather consistently. With this speedy advancement in innovation, huge development has been seen in the worldwide computerization industry. The utilization of robotization strategies is in ceaseless development and it is expected for an anticipated future. Robotic Process Automation is one of the surprises in the computerization business and extends higher likely to the extent that use and staff execution in the approaching year is ordinary. Just like the advantage of making mundane tasks more reliable, quicker, and with greater outcomes. With such distinct advantages, it's hard not to become exuberant with mechanization, but rather bouncing in aimlessly can present huge outcomes while attempting to scale or assess your ROI. Huge undertakings are as yet battling to scale RPA (just 3% of bot arrangements arrive at scale). The business processes they decide to robotize might be a contributor to the issue. Despite the fact that the amazing open doors and possibilities for Robotic Process Automation are adequate, truly, RPA isn't appropriate for each cycle. We've consistently supported that one of the keys to scaling RPA, is picking the right cycles to automate.

Abstract: This paper introduces anongoing project on the surveillance of speed vehicles and which makes more noise on the road. Noise pollution created by vehicles on urban roads is becoming more severe. To enforce current measures,we developed a vehicular noise surveillance system including a vehicle speed measurement method. Samples ofvehicular noise were recorded on-site using IR sensor. When IR Sensor detects more vehicle noise greater than 90 decibels, then the transmitter sends the data to the receiver. The receiver recieves the data then makes the RaspberryPi camera on. RaspberryPi camera captures the vehicle number plate and rider photo or video using OCR and the buzzer will turn on it gives the intimation and at the same time the data will store in cloud. License Platform Detection is a computer technology that enables us to identify digital images on the platform automatically. Different operations are covered in this system,such as imaging, number pad locations, alphanumeric character truncation and OCR. The final objective of the system is to construct and create efficient image processing procedures and techniques to position a licensing platter on the Open Computer View Library picture. It was used and implemented the KNN algorithm and python programming language. The technology can be used in different industries such as security, highway speed detection, lighting violations, manuscript documents, automatic charging system, etc. Auto plate recognition is an integratedtechnology which identifies the auto licence plate. Auto plate auto recognition. Multiple applications include complex safety systems, public spaces, parking andurban traffic control. Automatic Vehicle License Plate Recognition (AVLPR) has undesirable aspects because of many effects, such as light and speed.

Digital Divide and Digital Inequality in Global Food Systems
Authors: Revenko Lilia S. , Revenko Nikolay S.
Published: July 2022

The article explores the impact of the digital divide and digital inequality on the transformation processes in the world’s food sector through the lens of a new paradigm developed in preparation of the September 2021 UN Food Systems Summit. The purpose of the study is to identify the main causes of the deepening digital inequality in the food sector and ways to overcome it. The authors’ methodology of interdisciplinary comprehensive analysis of socio-economic processes makes it possible to identify the most disruptive points that inhibit food provision to the global population in the context of digitalization. It is argued that the digital inequality in various food systems is based on the multi-speed nature of digitalization processes in individual countries and among groups of economic entities, and this creates new competitive landscape and, consequently, a new ratio of market advantages and risks. It is concluded that the digital inequality in the global food systems has implication beyond the market profoundly affecting social outcomes. It exacerbates the food security problem in terms of economic affordability of food due to a decrease or loss of income of the rural population, who lose their jobs in the digitalization context, and also generates new risks of functioning in digital ecosystems. This situation makes it difficult to achieve the 2030 Sustainable Development Goals (SDG), namely SDG-2 and related goals. However, the impact of government regulation of the food sector on overcoming digital inequality remains ambiguous.

Methodological approaches to assessment of aesthetic properties of landscapes
Authors: Lozbeneva Elina A.
Published: July 2022

Aesthetic properties are important characteristics of any territory. Currently, there are quite a few methodological developments for evaluating the aesthetic properties of landscapes. Conventionally, they can be divided into traditional assessment methods, where the assessment is based solely on fi surveys, and the other - those based on modern approach, in which fi ld research is supplemented by GIS technologies. In turn, fi surveys are highly labor-intensive and, as a result, are usually carried out for small key areas or individual routes. With the introduction of GIS and remote sensing data (RSD) of high spatial resolution, it became possible without much diffi to assess many indicators of the aesthetic attractiveness of landscapes. This article is devoted to an overview of development of modern methodological approaches to assessing the aesthetic properties of landscapes. The paper opens with historic review of the aesthetic studies of landscapes, then discusses theoretical questions such as the defi of the concept of “aesthetics of the landscape” and the exploration of aesthetic perception and, fi ally, presents a case study of application of GIS technologies for aesthetic evaluation of landscapes.

Authors: Kurochkin Ivan N. , Trifonova Tatiana A. , Chugay Natalia V.
Published: July 2022

The processes of urbanization lead to a negative impact on the natural environment and disruption of the balance of ecosystems. The paper considers the main trends in changing the structure of land use of the Vladimir city district in the period 2001-2020. The analysis of the functional zoning of the territory is carried out. The largest share in the structure of land use is occupied by forests in the southwest and southeast of the study area. The territory occupied by them is anthropogenically slightly modified. An increase in the area of forests on the territory of the urban district has been established; a decrease in the areas occupied by meadows and deposits. The analysis of the spatial distribution of green spaces showed that the area of green areas did not correspond to the recommended values. There is a sharp decline in the area of arable land, stagnation of industry, the growth of urbanized areas. There is a restructuring of the road network, which is due to an increase in the number of vehicles, and as a result, an increase in the anthropogenic load on natural areas.

Authors: Estrada Mario Arturo Ruiz , Koutronas Evangelos
Published: July 2022

This paper establishes conceptual foundations for analyzing the economic dimensions of regional or global emerging and endemic infectious disease events, such as the case of Covid-19. The Covid-19 Global Economic Impact Simulator attempts to identify the Covid-19 transmission parameters and forecast its trajectories. The model introduces seven basic indicators - (i) the Covid-19 contagious spread intensity rate (S.I.), (ii) the treatment level for Covid-19 infected cases rate (T); (iii) the number of Covid-19 causalities rate (-C); (iv) the economic wear from the Covid-19 epidemic rate (-Π); (v) the Covid-19 contagious cases multiplier rate (M); (vi) the total economic leaking from the Covid-19 epidemic rate (-Ltotal); and (vii) the economic desgrowth from the Covid-19 epidemic rate (-δ2019-nCoV). Findings show that Covid-19 exhibits parallel spatial and temporal conditions with the related R.N.A. virus family but carries distinct infection signatures and magnitude of virus replication. Covid-19 ferocity can trigger a severe public health emergency in China with significant impacts on the domestic and world economies.

Authors: Y.M Abdullahi , A. Anuar
Published: July 2022

The use of public-private partnership (PPP) strategies in the delivery of public works projects has grown in popularity as an alternative delivery model, although its implementation has met with inconsistent success. Numerous studies have linked the effectiveness of public-private partnerships (PPPs) to the unique characteristics of various administrative environments. This comparative research used a case study technique to analyze the similarities and contrasts between the essential elements that determine the success of public-private partnership (PPP) housing projects in Malaysia and Nigeria. However, whereas ‘equitable risk allocation', ‘stable political system', and ‘reputable developer' are the most key success variables in Nigeria, ‘action against errant developer', ‘consistent monitoring, and homebuyer demands' are still the most crucial success aspects in Malaysia, according to the research. The results contribute to a better understanding of the environmental factors that affect the relative relevance of CSFs in public-private partnerships in underdeveloped countries.
