Фибрилляция предсердий (ФП) является одной из главных проблем современной кардиологии. Распространенность сердечно-сосудистых заболеваний в популяции, недостаточный контроль факторов риска с одной стороны, увеличение продолжительности жизни и расширение возможностей выявления аритмии с другой привели к значительному росту числа случаев ФП. Течение ФП осложняется развитием инсульта, системных эмболий, сердечной недостаточности, повышается риск внезапной сердечной смерти. Для предупреждения осложнений большинству пациентов требуется постоянный прием пероральной антикоагулянтной (ОАК) терапии, а также лечение сердечно-сосудистых и коморбидных заболеваний. Приверженность к терапии ОАК и контроль факторов риска инсульта и кровотечений являются важными условиями эффективности и безопасности лечения, однако у многих пациентов приверженность остается низкой. Причиной этому служит целый ряд факторов, как связанных с самим пациентом, так и зависящих от врача и системы здравоохранения. Представленный обзор посвящен обсуждению возможных путей повышения приверженности к терапии и их роли для улучшения прогноза у пациентов с ФП с фокусом на их обучение, интегрированную помощь, использование программных средств.

Atrial fibrillation (AF) is one of the major concerns in current cardiology practice. High prevalence of cardiovascular diseases in the population and poor control of the risk factors, as well as the increase of life expectancy and improved arrhythmia detection resulted in continuous increase of the number of AF cases. Stroke and systemic embolism, heart failure, and increased risk of sudden cardiac death are the complications of AF clinical course. For the vast majority of AF patients, the continuous oral anticoagulation (OAC) is required. Management of cardiovascular and comorbid diseases is essential to prevent complications as well. Medication adherence and control of strokeand bleeding risk factors ensure effectiveness and safety of OAC. Nonetheless, adherence remains low in many patients. The latter depends on the patient-related factors. In addition, the impact of physician and health care system is notable. In the current review, we discuss possible approaches to improve adherence and their prognostic impact in patients with AF with the focus on patients’ education, integrated medical care, and use of software tools.
Amistades, solidaridades y conflictos. Reflexiones en torno al concepto de homosociabilidad desde las cartas de Mari (S. XVIII a. C. Siria)

Authors: Suwella Siti Ilya , Riandari Fristi
Published: February 2022

Diabetes is a very dangerous disease because diabetes can attack other organs of the body so that it can cause death. This is due to the lack of technology-based information that can help determine the symptoms of diabetes. With the limited number of diabetes experts, an expert system is needed to diagnose diabetes. The method applied to the system is the Dempster Shafer method, by determining 17 symptoms and 3 types of disease, as well as compiling a rule base in determining the relationship of each symptom so that the results in the calculation achieve 100% accurate results. This method has 5 steps in its completion. The results showed that the Dempster Shafer method could be used to diagnose the symptoms of diabetes. So that the existence of this system can help the wider community in finding information about the symptoms of diabetes.

Authors: Laia Taozara , Hasugian Penda Sudarto
Published: February 2022

Eye disease due to frequent use of computers is one of the dangerous diseases in health because if not treated quickly it will result in blindness. These eye diseases can be diagnosed through the symptoms that arise in humans or through their clinical picture, through these symptoms an expert system can be made to make a diagnosis. An expert system is a system that seeks to adopt human knowledge to a computer that is built to solve problems like an expert. The expert system made in carrying out the diagnosis uses the Bayes theorem method to calculate the probability of an event occurring based on the influence obtained from the results of observations and experts. The system was built using PHP and MySQL programming as a database. The method used for tracing is Bayes' theorem. While the results of the diagnosis will inform about the results of the diagnosis containing a list of symptoms entered, information on the results of the rules regarding the eye disease suffered and information about possible treatments that can be carried out as well as treatment solutions.
Presence of antinutritional factors in legumes

Published: February 2022

Legumes are one of the main sources of vegetable protein, and it has also been shown that, after consumption, beneficial effects can be obtained for human health, since they can help reduce blood glucose levels, as they are considered a low glycemic index food, promote bone health, and contain bioactive compounds with different biological activities such as hypotensive or hypocholesterolemic, among others. This group of foods are considered complete foods since they contain proteins, carbohydrates, minerals, vitamins, among other nutritional components; however, they also have antinutritional factors (ANF), which are defined as non-fibrous natural substances that can cause a negative effect on the nutritional value of some foods, as well as on health since they hinder or inhibit the assimilation of some nutrients. For this reason, it is of great importance to apply processing methods to reduce or eliminate the presence of these ANF in legumes.
Bioethanol production of cheese whey in continuous culture

Published: February 2022

The cheese industry produces a large amount of waste, the equivalent of 9L of cheese whey for every 10L of milk (Murari et al., 2018; Pendon et al., 2021; Sar et al., 2021). Whey is composed by lactose and proteins, mainly (Murari et al., 2018; Murari et al., 2019; Tesfaw et al., 2021). In most cases, cheese whey had not added value or specific use, being discarded and causing very important environmental implications (Maruri et al., 2018; Tesfaw et al., 2021; Sar et al., 2021). In the present study, the production of bioethanol from cheese whey were analyzed, using Kluyveromyces marxianus as inoculum, under continuous culture conditions (28°C, agitation at 100 rpm, aeration at 1 vvm, feed at 8.63 mL/min), where it was established that is possible to obtain yields of 0.62 g of ethanol per g of lactose in the first 18 h, this makes it feasible for the continuous production of ethanol with cheese whey with minimal pretreatment.

Identifying Effective Teachers: Highlights from Four Classroom Observation Tools
Authors: Filmer Deon , Molina Ezequiel , Wane Waly
Published: February 2022

Teachers explain a significant share of variation across students’ achievement (Araujo et al., 2016; Bold et al., 2019; Dobbie and Fryer, 2013). But these achievements are poorly correlated with teachers’ observable characteristics including age, gender, education, experience, and hours in the school (Aaronson et al., 2007; Kane and Staiger, 2008; Rockoff et al., 2008). This suggests there could be other factors such as teachers’ content knowledge, pedagogical knowledge, classroom behaviour, and other practices that are potentially important determinants of students’ academic performance. There is growing interest in understanding these factors and exploring how they impact student learning. This has led to an increase in the development and use of structured classroom observation tools to observe, analyse, and measure teaching and learning practices within classrooms. These tools have provided information on current teaching practices and improvements over time.

Cardiac surgery involves both morbidity and mortality. Length of hospital stay can depend on many
factors. The aim of this study is to analyse the factor which were responsible for prolonged hospital stay in
a tertiary care center .We retrospectively analysed cardiac surgery patients over a period of four months from hospital registers.
Only elective surgery was considered. 83 patients were studied.
The patients were divided into two groups(Group 1 and Group 2) based on length of hospital stay in cardiac intensive care
postoperatively. We considered prolonged hospital stay if patient was discharged after 4th postoperative day. Data was
analysed using Chi squared test , One way ANOVA and Unpaired t test. We observed that the mean duration of stay in the
intensive care unit during this study period was 3.98 days in Group 1 and 6 days in Group 2 which is signicant(t=-11.70, and
p<0.0001).Diabetes mellitus, hypertension ,left ventricular systolic dysfunction ,chronic kidney disease and increased

TheKleine-Levin syndrome (KLS)is classied among rare diseases[1, 2].
It belongs to the central hypersomnias said to be recurrent and dened
according to the International Classication of Sleepiness Disorders, 3rd
version (ICSD-3), revised in 2014. For the ICSD-3, the Kleine-Levin
syndrome is a disorder characterized by recurrent episodes of hypersomnia andhyperphagia (rapidconsumptionof a large amountoffood),usually
with onset in early adolescence inmales but occasionally in laterlife and in
women.Amonosymptomatic form of the disorder with hypersomnia only
can occur with- out binge eating or hypersexuality [1]. Usually affecting
adolescent males, episodes normally last up to a few weeks and terminate
with total and spontaneous recovery. Possibly rst reported by Brierre de
Bosmont in 1862, the condition however received its name from Willi
Kleinewho,in1925,reporteda seriesof casesofperiodichypersomnia and
also Max Levin who described a case of periodic hypersomnia and
excessive appetite in1930[2].The exactprevalence remainsunknown.But
it seems very rare: around one to two cases per million. All cases are not

Break from Tradition: Questioning the Primacy of Self-Regulation in American Securities Law
Authors: Sanders John
Published: February 2022

This Comment outlines the circular path of American securities law—one that begins and ends with the primacy of self-regulation. Part I of this paper describes American securities law between 1792 and 1911 (the “Buttonwood Era”). In this era, a group of New York stock brokers utilized private contract law to create securities regulation for their private club, thereby establishing a tradition of self-regulation. Part II describes a short period of history in which individual states attempted to regulate the securities market through state statutes, the so-called “Blue Sky Laws.” Part III details the creation of the federal securities law regime during the New Deal Era. Part IV describes the transition from centralized federal regulation of the securities industry to the return of the primacy of self-regulation. Part V serves as the paper’s conclusion.

Topology of Augmented Bergman Complexes
Authors: Bullock Elisabeth , Kelley Aidan , Reiner Victor , Ren Kevin , Shemy Gahl , Shen Dawei , Sun Brian , Zhang Zhichun Joy
Published: February 2022

The augmented Bergman complex of a matroid is a simplicial complex introduced recently in work of Braden, Huh, Matherne, Proudfoot and Wang.  It may be viewed as a hybrid of two well-studied pure shellable simplicial complexes associated to matroids: the independent set complex and Bergman complex.

It is shown here that the augmented Bergman complex is also shellable, via two different families of shelling orders.  Furthermore, comparing the description of its homotopy type induced from the two shellings re-interprets a known convolution formula counting bases of the matroid. The representation of the automorphism group of the matroid on the homology of the augmented Bergman complex turns out to have a surprisingly simple description. This last fact is generalized to closures beyond those coming from a matroid.

Architecture is closely related to masculine traits due to the intervention of experts in the modern era. Existence became greatly reduced because of the feminism movement in architecture that had taken the attention of activists of architectural practice. Therefore, to bring back insights on the concept of masculine architecture, this research was conducted. In this study, qualitative descriptives were used as a method, as was the concept of masculine architecture that was not expected to be measured through quantitative data. In this method is very focused on the literature data due to the current conditions that can not make a direct visit to the site of the case study. The preferred case study is the Guggenheim museum in Bilbao, Spain. In data collection of course refers to the principles of masculine architecture. These principles include natural impressions on elements, color selection, industrial-style ornaments, and the use of steel materials. Some of these principles are further identified in the architectural elements that are considered capable of displaying a masculine architectural impression on this Guggenheim museum building. The result of this identification proves that every principle of masculine architecture is able to be presented very well to the building elements of this Guggenheim museum. In addition, we also find about the implementation strategy that is considered optimal to bring the impression of masculine architecture to a museum building, while still presenting something innovative but still has its own characteristics.

This research discusses the dissemination of education policy by looking at the responses and insights of students, lecturers, and education staff at the University of Muhammadiyah Makassar towards the Merdeka Belajar-Kampus Merdeka (MBKM). The biggest challenge in implementing educational policies in higher education is the percentage of understanding of the academic community and their readiness to implement education policy packages implemented by the government. In this study, a qualitative method was used by using a case study at the University of Muhammadiyah Makassar. The data was obtained from the results of a survey to students, lecturers, and education staff conducted by the MBKM Grant Team of the University of Muhammadiyah Makassar through a survey platform and survey questions facilitated by the Ministry of Education and Culture of the Republic of Indonesia starting on 18-22 December 2021. The results of the survey processed using the Nvivo application. There have been various responses regarding the Independent Learning-Kampus Merdeka Program and it can be concluded that the dissemination of the MBKM policy still needs to be maximized, because there are still many educators and students who do not know the nature of the policy.

Does Service Provider Matter During a Pandemic? COVID-19 Cases and Deaths Among Nonprofit vs. For-Profit Assisted Living Facilities in Florida
Authors: Carroll Deborah , Larson Sarah
Published: February 2022

When COVID-19 hit the U.S. in early 2020, individuals aged 65+ were identified as a higher risk population. In Florida, Governor DeSantis issued Emergency Order 20-006 to prohibit visitation to facilities housing groups of high-risk people, including assisted living facilities (ALFs). Regardless, 672 ALFs of the 3,019 in Florida had reported at least one positive case of COVID-19 by a resident or staff member as of June 30, 2020. Prior research has highlighted the differences in service delivery between nonprofit and for-profit health care providers. This manuscript fills the void of minimal research on quality of care differences among ALFs based on ownership status. We find that nonprofit ALFs have experienced fewer positive cases of COVID-19 among their residents, but less evidence of a difference between nonprofit and for-profit ALFs in terms of resident deaths. We also find evidence that the type of nursing services matters for protecting ALF residents from COVID-19.
The Impact of Systemic Racism on Responses to and Recovery from COVID-19: A Comparative Analysis of Policy and Practice in New York City and Detroit
Authors: Martin-Howard Simone , Damour Ruth , Robinson Tracey
Published: February 2022

When COVID-19 was first reported in the United States in spring 2020, it illuminated society to the vast inequities that racially marginalized populations face in comparison to their White counterparts. Metropolitan areas, in particular, were hit the hardest by the pandemic. New York City and Detroit, cities with large numbers of racially marginalized populations, experienced high COVID-19 test positivity rates during the pandemic’s first and second waves. It is the aim of this research note to provide policymakers, practitioners, and healthcare personnel with an overview of response and recovery efforts through an analysis of the intersection between racially marginalized groups and access to healthcare in New York City and Detroit. We propose three recommendations: 1) increased centralized data on the differences between racially marginalized populations and non-minorities; 2) additional federal funding to local health departments; and 3) the utilization of faith-based and community-based organizations as additional COVID-19 testing sites.

Authors: Irfan  , Subagio Bambang Sugeng , Hariyadi Eri Susanto , Maha Indra
Published: February 2022

Pre-Vulcanized Liquid Natural Rubber (PVLNR) modified asphalt leaves problems such as increasing the viscosity, thereby increasing the mixing and compaction temperature up to 175 °C, accelerating the ageing process. Therefore it is necessary to do developing methods using PVLNR at lower mixing temperatures requires warm-mix technology. This study aimed to evaluate the use of PVLNR modified asphalt in warm mix asphalt (WMA). Laboratory testing includes rheological modified asphalt, the workability analysis, Resilient Modulus and Deformation. The results showed that the PVLNR content decreased penetration increased the softening point and asphalt viscosity. In addition, additive Rediset LQ plays a role in reducing asphalt viscosity. The advantages of PVLNR modified asphalt are increasing elastic recovery, saving asphalt consumption and increasing the Modulus of hot mix asphalt rubber (HAR) and warm mix asphalt rubber (WAR). In addition, the Rutting resistance of WAR is better than that of HMA and WMA.

Among all additive manufacturing techniques, fused deposition modeling (FDM) has been used the most extensively to fabricate continuous fiber reinforced polymers. Onyx, a short carbon fiber reinforced PA6 composite material developed by Markforged, has received widespread attention, and been employed as matrix in FDM-fabricated composites. This study investigates the tensile properties of continuous glass fiber (GF) reinforced Onyx (CGFRO) composites under quasi-static loading. CGFRO contains three different components, which are short carbon fiber in micrometer scale, continuous glass fiber and polyamide-d thermoplastic. The synergistic reinforcing behavior of these three components was evaluated experimentally by testing Onyx material, and CGFRO with different volume fractions of fibers (Vf). It was found that the failure mode of Onyx was different from that of GF/Onyx and the deformation modes of GF/Onyx varied with the volume fraction of glass fiber. The tensile properties of CGFRO increased with glass fiber volume fractions, where 42% Vf specimens exhibited the highest tensile modulus and strength of 10 GPa and 383 MPa, respectively, which are approximately nine times higher than that of Onyx parent material.

In this paper, the thermal behavior of concrete blocks with different rubber ratios was examined experimentally. The rubber of 0%, 5%, 10%, 15%, and 20% used instead of fine aggregate in a concrete block raw materials. The size of the rubber granules used in this study is between 0-1 mm. The concrete approved mixing ratios are 1:2:1. The indoor solar simulator with 700 w/m2 light intensity was applied on the external surface of each block and thermocouples were used to measure the temperature on the external and internal surfaces. The other block surfaces are insulated. The results indicated that the use of rubber aggregate with the concrete block reduced the inner surface temperature by increasing the thermal resistance of the heat flux. ​For 20% rubber added, produce 8.5% low-weighted construction materials and with high thermal resistance that works to save energy consumed in the building sector.

For the realization of efficient production processes, an understanding of the appropriate application of metal working fluids (MWF) is necessary. In addition to knowledge about the process-related aspect of chip transport and the macroscopic cooling effect, the characteristics and properties of the lubrication film thickness and the cooling conditions in the area of the secondary shear zone on the chip surface, i.e. in the direct vicinity of the material separation, represent a fundamental scientific issue within production technology. In particular, these areas generate a high proportion of heat during machining, so that the local friction phenomena have a significant influence on the resulting edge zone of the produced component and the thermomechanical load on the tool. Currently, there are no numerical models and methods for mapping and predicting the lubrication film thickness that can be used in the sense of a targeted design of the cooling lubricant supply. The aim is to transfer the methods from the field of tribology of machine elements, which have already led to significant knowledge gains in this discipline, to machining and couple them to approaches already established in machining. To this end, experiments on tribometers have been performed as a first step. For example, an oscillating pin-on-plate tribometer was used. In this setup, a steel plate is doing oscillating motion against a fixed ball (diameter of 6 mm) under a defined load. The frictional force is recorded during the test. A MWF in a heated tank is used for the lubricant. Additional investigations on the film thickness were performed on an optical EHL (elasto-hydrodynamic lubrication) tribometer. In this setup, a ball rolls on a glass-disc and the resulting film thickness is measured by interferometry.For comparison, the influence of the MWF on the chip formation process in metal cutting was investigated on a special test rig (machine tool). This test rig allows high speed imaging and force measurements of an orthogonal cutting process while using MWFs. The first results show a reduced contact length between chip and tool as well as lower process forces for processes with MWFs compared to dry cutting processes. In future investigations, this test rig will be applied for the identification of the local friction coefficient between chip and tool. The data gained from the cutting test are compared with the output of the tribological test rigs.

In this study, the impact of tool pin profile on the dissimilar joining characteristics of aluminum alloy AA2017 and polycarbonate in friction stir welding (FSW) was examined. The tool pins made of SKD11 tool steel were used in the experiments of the FSW to join AA2017 and polycarbonate plates in a butt configuration at a tool rotation speed of 1320 and 1760 rpm and tool transverse speed of 60 mm/min. The tool shoulder diameter and tool pin height were set to 10 mm and 2 mm. The shapes of tool pin were cylindrical with and without groove, tapered cylindrical with and without groove, bobbin shaped with and without groove, square, triangular, pentagonal, hexagonal, oval, and ellipsoidal. The measurement of axial force was performed using a dynamometer. The changes in workpiece temperature at six locations during the process were measured using K-type thermocouples embedded in the plates. Microstructures of welded joints were examined by an optical microscope. Vickers Microhardness mapping was performed in and around the weld nugget zone, which is formed by the material flow between the two different base materials. From the result, the grooved tool pins generated less heat; while cylindrical, square, and oval type pins are also result in the superior properties of the welds during joining processes. Each tool pin had unique material flow behavior and weld formation, and the weld defects such as tunnel/voids occurred at the joint interface. The oval tool pin gives rise to the highest joint efficiency at a higher tool rotation speed, and the ellipsoidal tool pin generates the highest joint efficiency at a lower tool rotation speed was noticed.

To fabricate sandwich-structure composite of porous metal with nonporous surface layer, the nonporous skin layer was formed on surface of open-cell type nickel foam from aluminum powder by friction stir powder incremental forming (FSPIF) process. In this process, the surface pores of the foam were filled with the powder, then the powder and the cellular matrix near the surface of the foam were incrementally hammered by a rod-shaped tool without rotation. After that, the hammered surface of the foam was incrementally stirred by the tool at a very high rotation rate. The formed skin layer was composed of two layers; the friction stirred layer (relative density: above 0.90) in the upper part and the compact layer (relative density: 0.60–0.90) in the lower part. The friction stirred layer with a maximum thickness of 0.8 mm was formed on the surface of the foam without deforming the cellular matrix of the inside of the foam under the forming conditions; a tool rotation rate of 8000 rpm, a tool feed rate of 60 mm/min, a tool pushing pitch of 0.1 mm, and a total forming depth of 5.0 mm.

7000 series aluminum alloy is a high-strength alloy and used in a wide variety of products for the purpose of weight reduction in the field of transportation equipment and aerospace. In particularly, A7075 alloy has the highest strength and is expected to be further applied in a wide range of fields such as aircraft parts and sports equipment. However, it has high deformation resistance and is prone to surface defects called tearing. Tearing affects the productivity because it requires to lower the speed. Tearing is likely to occur under high temperature and high speed conditions. It is thought that the localization of melting of Zn-compounds and additive compounds occur due to heat generated during process leading to tearing. In this study, in order to increase the productivity without tearing, die surface quality was considered to prevent the effect of friction and generated heat at interface between tools and material. In addition, recrystallization was also eliminated by reducing friction because temperature does not increase up to the range of recrystallization temperatures. The AlCrN coating was used to improve die surface quality comparing to Nitriding. It was found that the tearing size and heat generated by using AlCrN coating were small. In addition, grain size was small and observed at the tearing region on the extruded surface. It is thought that the die coating can reduce the effect of friction at interface and prevent the recrystallization of the extruded surface. Furthermore, the localization of melting of Zn-compounds and additive compounds are also decreased. From above results, tearing sensitivity can be decreased by using coating to increase productivity speed of A7075 alloy.
