Published: December 2022

MarsWRF, the general circulation model of Mars, is one of the most
commonly used models to study the dust cycle in the Martian atmosphere.
It has been widely used to study the mechanisms of dust storms and their
effects on the Martian atmosphere. To better understand the ability of
MarsWRF to simulate the dust cycle on Mars, this study assesses the
current dust lifting schemes in the model, specifically the convective
lifting and wind stress schemes. It is found that, by tuning lifting
efficiency, the model with the convective lifting scheme can generally
reproduce the seasonal variation of the mid-level atmospheric
temperature (T15) but cannot reproduce the observed spatial distribution
of dust devils, which exhibits non-homogeneous (uniform) distribution in
the northern (southern) hemisphere. The model with the wind stress
lifting scheme can generally capture the observed magnitude of T15 and
column dust optical depth (CDOD) with properly tuned lifting efficiency
and threshold drag velocity. There is a discrepancy in the assessment of
modeling seasonal variations of dust with T15 and CDOD, which may be
partly due to the observational uncertainties related to T15 and CDOD
and the empirical modeling methods of Martian dust optical properties
and radiative effect. For the spatial distribution of dust, there are
significant simulation biases regardless of the tuning, which may be
caused by the biases in the dust lifting process and large-scale
atmospheric circulation. The analysis highlights that dust lifting
schemes need further improvement to better represent the dust cycle and
their impacts on Mars.
An Extensionally Fractured Upper Lithosphere on Io
Authors: Byrne Paul K. , Lopes Rosaly , Radebaugh Jani , Williams David A
Published: December 2022

The Jovian moon Io features hundreds of paterae, broad depressions often
filled with lava. The largest such example, Loki Patera, features a
large, polygonal, and fractured island in its center. This island may
reflect the fragmentation of the upper Ionian lithosphere by a shallow
magma body, facilitated by a great number of shallow extensional
structures. We propose a model for the Ionian lithosphere in which the
upper portion is heavily deformed by joints, normal faults, and graben
resulting from combined tidal, subsidence, and thermal stresses, and a
lower portion rife with major thrust faults formed by horizontal
compression of deeper crustal levels from the continued burial of
surface units. Some of those thrusts may be reactivated normal faults.
An extensionally fractured upper lithosphere accounts for the Loki
Patera island, for observations of more than 175 paterae with straight
edges, for the fact that almost 95% of Io’s surface is covered with
volcanic flow and plains units, and for widespread instances of mass
wasting within Io’s gigantic mountain blocks. Additional,
high-resolution image and topographic data are required to test this
hypothesized model for the moon’s lithosphere.
Long-lived (180 Myr) ductile flow within the Great Slave Lake shear zone
Authors: Šilerová Dana , Dyck Brendan , Cutts Jamie A , Larson Kyle
Published: December 2022

The Great Slave Lake shear zone (GSLsz) is a type example for deeply
eroded continental transform boundaries located in the Northwest
Territories, Canada. Formed during the oblique convergence of the
Archean Rae and Slave cratons, the GSLsz has accommodated up to 700 km
of dextral shear. Here we present the results of in situ U-Pb apatite
and titanite geochronology from 11 samples that were collected across
the strike of the shear zone. Both geochronometers record a
near-continuous history of ductile shear during crustal cooling and
exhumation that spans ca. 1920–1740 Ma. By integrating the
geochronological data with structural and metamorphic observations
across the structure, we propose a tectonic model for the shear zone
that consists of three stages. The first stage (ca. 1920–1880 Ma) is
characterized by strain accommodation along two coeval fault strands.
During the second stage (ca. 1880–1800 Ma), ductile shear ceases along
the northernmost fault strand and the locus of strain migrates
southwards towards the hinterland of the Rae cratonic margin. In the
third stage (ca. 1800–1740 Ma), ductile strain localizes back along the
southern of the two original fault strands, after which the present-day
surface level of the shear zone transitions to brittle shear. Our
results highlight both the significance of the lateral migration of the
zone of active deformation in major crustal shear zones as well as the
localization of strain along existing crustal structures.
Modeling the Dispersal of the San Francisco Bay Plume over the Northern and Central California Shelf

Published: December 2022

High-resolution simulations by the Regional Ocean Modeling System (ROMS)
were used to investigate the dispersal of the San Francisco Bay (SFB)
plume over the northern-central California continental shelf during the
period of 2011 to 2012. The modeled bulk dynamics of surface currents
and state variables showed many similarities to corresponding
observations. After entering the Pacific Ocean through the Golden Gate,
the SFB plume is dispersed across the shelf via three pathways: (i)
along the southern coast towards Monterey Bay, (ii) along the northern
coast towards Point Arena, and (iii) an offshore pathway restricted
within the shelf break. On the two-year mean timescale, the along-shore
zone of impact of the northward-dispersed plume is about 1.5 times
longer than that of the southern branch. Due to the opposite surface
Ekman transports induced by the northerly or southerly winds, the
southern plume branch occupies a broader cross-shore extent, roughly
twice as wide as the northern branch which extends roughly two times
deeper due to coastal downwelling. Besides these mean characteristics,
the SFB plume dispersal also shows considerable temporal variability in
response to various forcings, with wind and surface-current forcing most
strongly related to the dispersing direction. Applying
constituent-oriented age theory, we determine that it can be as long as
50 days since the SFB plume was last in contact with SFB before being
flushed away from the Gulf of the Farallones. This study sheds light on
the transport and fate of SFB plume and its impact zone with
implications for California’s marine ecosystems.

Bringing social biography to life course studies: Agency and reflexivity in education-to-work transitions in young adults’ biographies
Authors: Tomanovic Smiljka
Published: December 2022

The paper is based on my longitudinal qualitative study, which takes a
?social biography approach? to exploring and interpreting biographical
sequences in a person?s life course from early childhood to young adulthood.
Against the background of a recent debate that argues for bringing ?life?
back to life course research through the implementa?tion of qualitative
data, the paper explores how life course studies could gain from taking a
social biography approach to youth transitions. I focus on analysing
education-to-work transitions within the biographies of a young woman and a
young man from working-class families. The analysis shows that their
education-to-work transitions were not based on linear trajectories, but
their decision-making agency was path-dependent on their previous agency in
differ?ent biographical contexts, and also linked to the lives of
significant others. I argue that there is a heuristic benefit to including
reflexivity within a study of the life course through the actors?
interpretation of the impact of coun?try-specific ?opportunity structures?
on their education and employment. Analysis of the two biographies has also
revealed that the emotions and satisfaction displayed in the actors?
reflections also had an impact on their agency in relation to education and
work. After discussing the compatibility of the social biography approach
with life course studies, I conclude that life course studies benefit from
including a biographisation to the contextualisation of transition process.
Aging well? Social spending, age, and subjective wellbeing across Europe
Authors: Mentus Vladimir
Published: December 2022

The association between age and subjective wellbeing has been examined across
different samples and obser?vational time frames, most often indicating a
decline in subjective wellbeing with age or a U-shaped relation. Although
various contextual variables have been examined as moderators of this
relation, the moderating effect of social spending has not been investigated
so far. Given that social spending is potentially beneficial for wellbeing
and that social spending in Europe is primarily elderly-oriented, we assumed
that in countries with higher social spending expenditures, there is a more
positive effect of age on subjective wellbeing. We used cross-sectional
hierarchical linear modelling (HLM) analysis and the data from the ninth
round of the European Social Survey, including 29 countries. Our results
show that age is generally negatively related, while age squared is
positively related to subjec?tive wellbeing, indicating a U-shaped relation
between age and wellbeing. Additionally, social spending at the aggregate
level is a significant determinant of wellbeing at the individual level.
Most importantly, social spending is a significant positive moderator of
this association: with increasing social spending levels, aging is more
positively related to wellbeing.

Published: December 2022

OBJECTIVE: The aim of this study was to describe cross-sectional and longitudinal associations between glycated hemoglobin (HbA1c) levels and strategies to control type 2 diabetes with baseline levels and 8-year changes in a deficit accumulation frailty index (FI), a commonly used marker of biological aging.

RESEARCH DESIGN AND METHODS: We conducted exploratory analyses from 4,169 participants, ages 45-76, who were followed in the Action for Health in Diabetes (Look AHEAD) randomized controlled clinical trial, pooling data across intervention groups. We related baseline and 8-year levels of HbA1c with FI scores using analyses of variance and covariance. Associations between 8-year changes in FI and the use of diabetes medication classes and weight changes were assessed with control for HbA1c levels. Inverse probability weighting was used to assess bias associated with differential follow-up. 

RESULTS: Baseline and average HbA1c levels over time of <7%, as compared with >8%, were associated with less increase in FI scores over 8 years (both p<0.002). After adjustment for HbA1c, use of metformin and weight loss >5% were independently associated with slower increases in frailty.

CONCLUSIONS: Lower HbA1c levels among individuals with diabetes are associated with slower biological aging as captured by a deficit accumulation FI. Strategies to control diabetes through weight loss or metformin use may also slow aging.

Published: December 2022

Background. The recurrence of autoimmune liver diseases can lead to reduced survival of recipients and grafts.Aim. To study the incidence and impact of the recurrence of autoimmune liver diseases on graft survival; the effect of maintenance immunosuppression on the recurrence of autoimmune diseases in liver transplant recipientsMaterial and methods. Transplantation outcomes in 111 recipients (21 recipients operated on for autoimmune hepatitis, 50 recipients operated on for primary biliary cirrhosis, and 40 recipients operated on for primary sclerosing cholangitis) were analyzed retrospectively.Results. The recurrence of autoimmune hepatitis is observed in 5%, the recurrence of primary biliary cirrhosis is in 10%, and the recurrence of primary sclerosing cholangitis is in 17% of cases. Among patients with recurrence of autoimmune diseases, men accounted for 54%, while for only 31% in the subgroup of patients without relapse (p=0.004). The followup for recipients with relapse (64.5 (42.8;82.0) months) was comparable to the follow-up for recipients without relapse (46.5 (17.9;103.5) months, p=0.54). A ten-year graft survival was significantly higher in the group of recipients with recurrent autoimmune diseases compared with recipients without autoimmune diseases recurrence (p<0.0001).Conclusions. The recurrence of autoimmune diseases leads to a decrease in graft survival. The effect of immunosuppression components on the risk of recurrence of autoimmune diseases in the graft has not been established.

Maxillary Sinus Barotrauma in a Silent Maxillary Sinus Syndrome Scenario: Case Report
Authors: Santiago Monsalve
Published: December 2022

Barosinusitis is defined as an entity where damage to a paranasal sinus occurs secondary to sudden changes in atmospheric pressure. These dysbarisms respond to Boyle's Law where -given constant temperature- the pressure of a gas is inversely proportional to its volume. On the other hand, silent sinus syndrome is a pathology with few case reports in which the paranasal sinus undergoes a remodeling of its bony walls generating, in the case of the maxillary sinus, a descent of the eyeball and a herniation of the fat of the pterygopalatine fossa. The symptoms in these patients are insidious, so the diagnosis is usually fortuitous. The authors report a case where a diagnosis of silent maxillary sinus syndrome was made after an episode of severe maxillary barosinusitis.

Published: December 2022

El presente trabajo hace constancia del modo de percibir el “desarrollo” y “buena vida” por los miembros del cooperativismo costarricense, en base a cuatro estudios de caso en localidades La Cruz, Ciudad Neily, Buenos Aires y San Vito. Esta interesante experiencia nos impulsó a crear una propuesta de taller, que pudiera ser utilizado como herramienta en el proceso de creación de una cooperativa y/o a lo largo de su funcionamiento, con el fin de disminuir los riesgos de desentendimiento entre sus miembros, en el caso de decidir sobre los objetivos o derroteros de su actividad.

El cooperativismo, elemento de la economía social, es un eje de las propuestas alternativas al desarrollo y de desarrollo alternativo. Por lo tanto, estoy convencida que en el seno de estas entidades debería haber espacio para discutir sobre temas tan importantes.

Al mismo tiempo, el presente estudio forma parte de un proyecto más amplio financiado por el Centro Nacional de Ciencia de Polonia (no. 2018/29/B/ HS6/00187) titulado “Discourses and development dilemmas of Central American local communities”, en el marco delcual se realizó un trabajo de campo en el mes de enero 2021 y una serie de debates virtuales donde las diferentes perspectivas sobre el desarrollo en el contexto de la construcción de megaproyectos fueron analizados.
Estado regulador, saúde e envelhecimento: uma análise da atuação da ANS a favor do “rol taxativo”
Authors: Felix Jorge
Published: December 2022

O desfianciamento do Sistema Único de Saúde e o envelhecimento da população impulsionaram o crescimento do setor de Saúde Suplementar no Brasil que, atualmente, alcança 50 milhões de pessoas, cerca de 25% da população brasileira. Entre fevereiro e setembro de 2022, o país testemunhou um embate em torno de um aspecto da regulamentação do setor: a judicialização da cobertura dos planos de saúde, o chamado “rol da ANS”, a Agência Nacional de Saúde Suplementar. Esse artigo analisa a atuação da ANS e conclui que houve parcialidade a favor do setor privado, desrespeito às obrigações de impessoalidade e independência. Diante da dinâmica demográfica, à luz desse episódio, sugere-se uma revisão normativa e questionamentos do modelo de Estado regulador para se atender às demandas de saúde, sobretudo, da população idosa.
Elementos para um estudo da taxa de lucro: França, 1896-2019
Authors: Herrera Rémy , Long Zhiming , Ding Weinan
Published: December 2022

Considerando que a taxa de lucro constitui um indicador chave para a análise da evolução das economias capitalistas, este artigo tem como objetivo estudar o caso da França de 1896 a 2018, ou seja, 124 anos no total. A partir da série de estoque de capital produtivo, calcula-se a taxa de lucro no nível macroeconômico dentro de um quadro conceitual fiel a Marx. Ao longo desse período de mais de um século, são identificadas três ondas longas sucessivas, partes de uma tendência secular de queda da taxa de lucro francesa. Essa taxa se recuperou várias vezes durante os três subperíodos, mas finalmente se reorientou para baixo, com flutuações de amplitude cada vez mais reduzida e um desdobramento em uma espiral decrescente do capitalismo francês. A tendência de queda de longo prazo deve-se principalmente ao aumento da composição orgânica do capital.

Published: December 2022

Iryna Kochmar Vasyl Karabyn 1 Lviv State University of Life Safety 2Lviv State University of Life Safety Mining areas are centres of increased environmental danger. This is due to the development and operation of mines and subsequent beneficiation of coal, as well as the storage of significant volumes of empty waste rock in landfills. An important component of ensuring environmental safety is the investigation of the factors and ways of the impact of rock dumps on the state of the environment. In this regard, the article examines the forms of heavy metals found in the rock of the waste heap of the central coal enrichment plant "Chervonohradska" of the Lviv-Volyn coal basin. The environmental hazard factors caused by the distribution of various forms of lead, cadmium, zinc, and copper, based on establishing the migration capabilities of these elements in the technogenesis zone, are analyzed. It was determined that the gross content of lead reaches 16.32 mg/kg, cadmium – 5.84 mg/kg (exceeding clarke up to 29.2 times in siliceous siltstone and siltstone), zinc – 421 mg/kg (exceeding clarke up to 5.26 times in sandstone, siltstone and siliceous siltstone), copper – 112.89 mg/kg (exceeding clarke by 2 times in siltstone). The concentration coefficients of heavy metals in the samples were determined in relation to the gross form. The results of the research give a reason to evaluate the rocks of the waste dump in terms of the distribution of various forms of Pb, Cd, Zn and Cu as dangerous for the environment and unsuitable for use because in all the samples an excess content was observed in one form or another.

Task Partitioning Hybrid Algorithms for Multi-Core Processors
Authors: Aljwari Fatimah K.
Published: December 2022

Multi-core Processors Rapidly developing in the world we live in and Companies Manufacturers continuous efforts to manufacture faster and intelligent chips. The use of multi-core processors has become widespread in many areas; therefore, task Partitioning for multi-core processors has become a hot issue in the research community. Many types of research have been done on task Partitioning and Task Mapping from various perspectives by researchers. The existing partitioning task algorithms still have negatives, such as low usage of the processor or not making the most of the cores efficiency on the processor. However, partitioning tasks onto processors is a significant challenge among the challenges facing the multi-core processor. In this paper, to solve this challenge we proposed developing the framework that uses hybrid partitioning algorithms to mix the Blocking-Aware Algorithm with First-Fit Decreasing (FFD) algorithm, based on each of these algorithms advantages.

Authors: Al-Lami Hayder , Mohammed Murtadha Saeed , Ali Radhwan , Alshara Ahmed , Zahra Hussein Kareem Abdul
Published: December 2022

In the heat transfer, fluid flow and energy fields, baffles are an advanced enhancer to improve heat transfer and fluid mixing by working as an obstacle to the flow particles and then increasing the turbulence. The present paper numerically investigates the thermal performance of a circular pipe with a centralized baffle in two arrangements, with a Reynolds number (Re) (ranging from 10,000-50,000) under constant wall heat flux boundary conditions. Ansys Fluent software is used to solve the flow field considering six conical baffles with different Pitch ratios (PR) (from 1 to 5). Results show that baffles shape, arrangement, and PR have a significant impact on the properties of flow and heat transfer. The obtained results show an effective role for the baffles to promote thermal performance when it is used in heated pipes. Heat transfer rate is increased for the baffled pipe by 1-2 compared with the smooth pipe. Moreover, the best value of friction factor, thermal performance, and Nusselt number is recorded at PR= 5 at Re=30000 in the baffled pipe for the second arrangement.
Development of Fluid Bed Dryer Process Control Module for Fluidization and Drying of Pharmaceutical Powder
Authors: Bolarinwa Mojisola A. , Olorunda Paul A.
Published: December 2022

As the fluidization of powdered active ingredients is crucial before compressing into desired forms or shapes, the importance of the fluidized bed dryers cannot be over-emphasized. Many studies had been carried out to improve the fluidization of particle bed by measuring and controlling process parameters to achieve quality output, but the implementation of these proved cost intensive. This work was focused on developing a control module using conventional low-cost components for monitoring the drying process of fluidized bed dryer. The module was developed following design calculations of parameters required to determine its rated current capacities, and selection of required components. The components used were selected putting in mind cost and durability, without compromising their suitability in achieving the set objectives for the developed control module. Thereafter, a performance test was carried out to ascertain its performance characteristics. From the design calculations, the overall load (current) rating of the module was 13 amperes. Relays, temperature controller and push buttons were major components selected, putting in mind the overall module capacity of 13 amperes. The selected components suitably performed the expected control operations, and the efficiency was over 98%. The control module was able to regulate the drying procedure to achieve a reduced percentage moisture content of 1.4% at 850c drying temperature. The control module performed the expected function at a reduced cost when compared to control units being adopted in the industry for such purpose. Therefore, the module could be further explored for implementation on large scale commercial dryers.
Examining the Drivers of Land Use /Land Cover Change: A Case of the Kavango River Basin and its Immediate Environments in Namibia
Authors: Iortyom Enoch Terlumun , Haindongo Priscilla , Odoma Linda Afor
Published: December 2022

Understanding the drivers of land cover changes (LULCC) is very crucial for the development of management strategies as well as policy improvement and the sustenance of ecosystem services. This is crucial in preventing further degradation and proper planning of sustainable natural resources management. In this study, an attempt has been made to identify the drivers of LULCC in the Kavango East and West Regions of Namibia, from 1990 to 2018. Remotely Sensed Images were used to compute indices. Socio-economic surveys were conducted using structured interviews to share the past experiences of the local people, some key informants, and other stakeholders in the region. A combination of this information together with the Remote Sensing data was then used to derive the drivers of LULCC in the study area. Results of the study showed that changes were triggered by the interplay of more than five drivers identified and related to the environment, socio-economic, and other technical factors. In particular, the establishment and expansions of agricultural land, settlement, urbanization, and lumbering (for timber and crafting) were viewed by local people as the leading cause of deforestation. Other factors such as drought, flooding, and lumbering (for construction and firewood) cannot be undermined. Future studies will be targeted at assessing these drivers to evaluate their impacts on achieving sustainable development in the Kavango River Basin of Namibia and its immediate environments.
Analysis of Sub-Regional Drinking Water Services in Africa, 2000-2020
Authors: Ohwo Odafivwotu , Ndakara Emmanuel Ofudjaye
Published: December 2022

Safe drinking water is a basic necessity of life. However, meeting this need has been a major challenge in most countries in Africa. This study analyzed the sub-regional drinking water services in Africa from 2000-2020. The study sourced data from the Joint Monitoring Programme (JMP) reports for 2017 and 2021. The 2000 and 2020 estimated national basic drinking water coverage, disaggregated for rural and urban (RU) areas of African countries were extracted and analyzed. The findings revealed that basic water services in Africa were poorly provided in the sub-regions, particularly in the rural area, where the population not served was high. The results of the t-test (t4 = -8.078, p = 0.001, α = 0.05) and (t4 = -4.375, p = 0.012, α = 0.05) revealed that significant differences exist in basic water services between RU areas in 2000 and 2020, respectively. Similarly, the t-test (t4 = -6.668, p = 0.003, α = 0.05) also shows that significant progress exists in basic water services from 2000-2020 in the sub-regions. However, the national annual rate of service provision lag behind expected progress for the attainment of the drinking water target, as the projected 2030 coverage in the sub-regions fell short of the expected 100% coverage. Therefore, to achieve target 6.1 in the sub-regions, basic water services have to improve at least four-fold.
Motivations for Patronage: Early Modernist Literature as a Case Study
Authors: Crozier Walter R.
Published: December 2022

Patronage of early modernist English-language writers is investigated, drawing upon biographical source material. The process of identifying patrons started with Imagist poets in the first decades of the twentieth century followed by a search for their social connections with fellow writers and patrons. Fifteen patrons were identified who brought new money into the network of connections, twelve of them women. Analysis of their personal characteristics reveals a distinctive pattern of substantial, inherited financial resources, education, literary interests and unorthodox lifestyle, notably for the women in the sample. Explanations of motivation in terms of social identity, gift exchange and co-creation are discussed.

In the early 20th century, the idea of creating a state theatre in Greece matured, that was responsible for establishing the foundation of a national dramatic tradition, as well as of the art of histrionics which until that time was characterized by amateurism. The Royal Theatre opened its doors to the public in 1900 and was based on the model of German Court theatres. In other words, theatre was considered a superior form of art that had to be kept away from the lower social classes. The absence of a powerful urban class and the lack of cohesion between the urban class and the lower classes favored the role of the Court, which was influenced by Drama when it comes on shaping its public guise and consolidate its dominance, by ensuring that a specific theatre style, aesthetics and ideology were preserved. Shakespeare’s performances in Greece were based on uncritical copying of practices applied in Europe in the light of the country’s agonizing struggle to build a new national and urban class identity. The audience of the Royal Theatre was seeking its own identity within that phantasmagorical ambience; that is for points of convergence with the western model, so as to receive social recognition and feel self-justified, as participation in such events were classified as “cultured persons”. The theatrical environment itself and the utilization of works of the English poet's works played a role in solidifying the idea in Greece that Shakespeare’s plays are the exclusive privilege of the urban class.

The Anglican Church of Kenya (ACK) is the oldest church in Kenya and the largest protestant denomination in the country. Since religions were liberalized after the attainment of political independence in AD 1964, the church has experienced declining congregations due to the registration of new denominations, especially the Pentecostal ones. The decline has been noticeable from the beginning of the 21st Century but there are no reports of strategies to resolve the phenomenon. Since congregation members are the customers for a church, the declining phenomenon indicates a marketing problem that requires a marketing strategy. This research investigated how the ACK is operationalizing a marketing strategy and its influence on its sustainability. The ACK operates on standardized structures and a diocese is the highest independent unit. This research was conducted in the diocese of Kirinyaga as the unit of analysis with Wanguru Archdeaconry as the unit of observation. The independent variables were the elements of the marketing mix, namely Product, Promotion, Position and Price strategies while the dependent variable was the church sustainability.  Data collection involved 308 participants drawn from the 19 parishes in the Wanguru archdeaconry and included the church leadership and the congregation members. The research instruments were a semi-structured questionnaire and interviews. For the Product variable, the research applied the Maslow Hierarchy of needs theory while for the promotion variable, it was the AIDA Model (Attention, Interest, Desire and Action). For the positioning strategy, the Segmentation, Targeting and Positioning (STP) Model was applied while the Value-Based Pricing theory was used for the price strategy. For church sustainability, the research applied the Triple Bottom Line model. Data analysis was conducted using Structural Package for Social Sciences (SPSS). The results indicated that the ACK has not operationalized an effective marketing strategy for while the Gospel as the marketing product of the church was highly rated, there were low scores for Promotion, Position and Price strategies.

Employee performance can be measured by their presence or attendance, which applies to both civil servants and non-civil servants. Because the attendance system still uses the manual technique, it is considered inefficient due to the potential for data fraud and attendance problems. In addition, the government is adopting precautions against viruses in office buildings to maintain business continuity while the pandemic is being addressed. The goal of this study was to employ a facial recognition system and temperature measurement to lower the danger of COVID 19 transmission while also minimizing paper use by using a facial recognition system as a substitute for presences. It has so far permitted the digitization of formerly manual sights. The OpenCV library allows computers to detect faces using the haar cascade classifier approach and Python as a programming language. A Logitech C930e webcam with a resolution of 1080p at 30fps was used to capture facial data, which was then processed on a Raspberry Pi 4 microprocessor. It uses an MLX90614 sensor to monitor body temperature, which is controlled by anArduino Uno microcontroller. It is well integrated into the database based on body temperature testing and facial recognition. The development of a more accurate temperature sensor reading method for distance and employee body temperature is a priority for future research.

To get comfortable air, it can be done by using an air conditioner or air cooler. The electrical power used for the air cooler is relatively lower. This research aims to see the effect of the number of cooling pads on the output air condition and on the effectiveness of the air cooler. The research was conducted experimentally. The research was conducted by varying the number of cooling pads used, thick. The distance between the cooling pads is 1.5 cm. The air temperature inlet of the air cooler has a dry bulb air temperature of 30𝑜𝐶 with an air humidity (RH) of 60%. The lowest dry bulb air temperature achieved was 24,04𝑜𝐶 when the number of cooling pads was 6 pieces. The highest air cooler effectiveness achieved was 0.99. Research has given satisfactory results. However, research can be developed by varying the cooling pad material or cooling pad pattern in order to obtain a small number of cooling pads.

Currently, the issue of the relationship between gut microbiota and juvenile idiopathic arthritis (JIA) is still relevant. The study was aimed to assess alterations in the gut microbiota taxonomic composition and estimate the relationship between these alterations and cortisol, melatonin, and TNFα at the genus level in patients with JIA. The comparative cross-sectional study involved 65 patients with JIA (index group) and 60 healthy children (control group). The gut microbiota taxonomic composition and plasma levels of cortisol, melatonin, and TNFα were assessed. The following alterations of the gut microbiota taxonomic composition were found in patients with JIA: the significantly decreased abundance of Anaerostipes (р = 0.042), Lachnospira (р = 0.034), Roseburia (р = 0.002), Coprococcus (р = 0.014), Dialister (р = 0.003) and the increase in the abundance of Ruminococcus (р = 0.012). There were significant correlations of cortisol levels with the abundance of Lachnospira (r = –0.44; p = 0.001), melatonin concentrations and the abundance of Coprococcus (r = –0.48; p = 0.023), the levels of TNFα and the abundance of Ruminococcus (r = 0.52; p = 0.001). The association of the Lachnospira, Roseburia, and Ruminococcus abundance with the higher DAS28 scores was discovered (r = –0.57; p = 0.002; r = –0.44; p = 0.002; r = 0.54; p = 0.032, respectively). The findings provide additional information about the features of gut microbiota alterations and their correlation with some hormone and inflammatory biomarkers associated with JIA, that could provide the basis for further research and possibly for new approaches to treatment of this disorder.

Based on the results of the pre-survey, what became a phenomenon in this study was that there was an imbalance between the sale of batteries at high prices and batteries at medium and low prices. In connection with these problems, the formulation of the problem in this study is "How is the relationship between price and battery purchase decisions?". From these problems, the purpose of this study is to determine the relationship between price and battery purchase decisions. The method used in this research is the explenatory survey method, which is a survey used to explain the causal relationship between two variables through hypothesis testing which is formulated or often referred to as explanatory research. The data analysis techniques used in this study were product moment, partial t test, and r2 determination. Based on data analysis carried out using the product moment formula, it is obtained that the R count of 0.950 is greater than the R table at the 0.05 significance level which indicates that the price is closely related to the purchase decision. The t test shows that the value of T is greater than the T table which explains that the price variable is positively and significantly related to the purchase decision. Furthermore, it is proven by the calculation of R determination which shows the R2 value of 90.3%, which means that the price variable contacts the purchase decision of 90.3. % so that the remaining 9.7% is related to other variables not examined.
