Home renovation assistance is an effort to reduce the burden on the poor. Home renovation is an activity to improve people's houses that are no longer suitable to be occupied. To determine whether or not it is appropriate, residents must meet predetermined criteria. The program that has been running so far is still very complicated in the processing of community data, as well as the selection process for prospective recipients, because it requires precision to determine which families are truly entitled to receive house renovation assistance, because the process is still manual. So we need a decision support system using the saw method that can help in determining who has the right to take precedence in getting home surgery assistance. The purpose in making this application is to help those responsible for making decisions easier, as well as preventing mistakes and fraud and making it easier to determine the values of community data criteria that are truly entitled to receive house renovation assistance. Community data processing for the assessment process can be operated with a computer device through an application system that uses PHP programming and uses a MySQL database Keywords: php, spk, saw method, Home Surgery, system, Javascript

Newton method is one of the most frequently used methods to find solutions to the roots of nonlinear equations. Along with the development of science, Newton's method has undergone various modifications. One of them is the hasanov method and the newton method variant (vmn), with a higher order of convergence. In this journal focuses on the three-step iteration method in which the order of convergence is higher than the three methods. To find the convergence order of the three-step iteration method requires a program that can support the analytical results of both methods. One of them using the help of the matlab program. Which will then be compared with numerical simulations also using the matlab program. Keywords : newton method, newton method variant, Hasanov Method and order of convergence
Laboratory Evaluation of Modified Asphalt Mixes Using Nanomaterial
Authors: Johnson Thomas W. , Hashemian Leila 
Published: July 2020

Abstract
More demands on pavement—including increasing temperature variability and precipitation and higher loading conditions, along with an increase in the rate of load applications—result in decreased pavement performance and reduce its service life. Three major distresses identified with asphalt pavements are rutting, fatigue cracking, and thermal cracking. Polymers have been frequently used for modification of asphalt binders to improve pavement performance and reduce pavement distress. However, there are problems associated with incompatibility between the modifier (polymer) and the binder as well as a reduction in the aging resistance of the asphalt. Furthermore, asphalt modification with polymers can result in operational difficulties as well as a significant increase in cost. This paper investigates the application of several nanomaterials, including nanoclays (halloysite and bentonite) and cellulose nanocrystals, as promising alternatives to improve asphalt performance and increase the service life of asphalt pavements. Using the Superior Performing Asphalt Pavement (SuperPave) asphalt mixture design and analysis system, the rheological properties of nanomodified asphalt binder and mechanical properties of the resulting asphalt mixes were evaluated at low and high temperatures. Results showed a noticeable improvement in the high-temperature properties of the modified asphalt mixes, with no significant effect on the low-temperature properties of the asphalt mixes or rheological properties of the modified asphalt binder. Considering the cost of the nanomaterials, it was concluded that they may provide a cost-effective alternative for asphalt modification.

Abstract
Round-robin (RR) tests carried out under the direction of the Technical Committee 4, “Polymers, Polymer Composites and Adhesives,” of the European Structural Integrity Society (ESIS TC4) showed that the multispecimen methodology employed for the construction of the crack growth resistance curve (J vs crack extension, Δa) of polymers often does not provide reliable data because of the uncertainties associated with the measurement of Δa. With this in mind, the ESIS TC4 attention has been more recently focused on the analysis of a testing scheme based on the load separation criterion, which does not require the measurement of Δa. With the aim to employ this new approach into a standardized procedure, the degree of reproducibility of the results obtainable with the application of this testing scheme to ductile polymers has been assessed by means of multilaboratory RR testing exercises that started in 2011. An ESIS TC4 reference draft protocol was prepared and 10 laboratories participated in the RR activities. The present work describes the load separation criterion-based testing procedure recently examined by ESIS TC4 and gives a summary of the results obtained in the RR activities, which appear encouraging.

Abstract
Metal matrix composites are considered as suitable materials for enhancing the properties of materials used for automobile and aerospace sectors. This research work is about magnesium matrix composites reinforced with 7 wt. % of titanium carbide and fly ash fabricated by stir casting technique. The particle distribution of the reinforcements in matrix material was examined by using optical microscope and scanning electron microscopy technique. The mechanical and microstructural properties of composites were investigated and compared with stir-cast pure magnesium. Titanium carbide and fly ash–reinforced composite showed around a 55.5 % and 33.3 % increase in hardness, respectively. Titanium carbide–reinforced composite displayed more wear resistance as related to fly ash composite and stir-cast pure magnesium. There was also an increase in tensile strength of composites as equated to stir-cast pure magnesium. The fracture behavior of composites showed the presence of surface cracks, voids, and particles of reinforced material in composites. As compared to titanium carbide–based composite, fly ash composite showed wider voids and agglomeration of fly ash particles in fracture surface. However, the fractured surface of pure magnesium showed deep voids as compared to composites along with elongated dimples.

An anti-lock braking system (ABS) is a basic skid control system that can prevent the tire from locking up. In an emergency braking situation, a high possibility that the skidding phenomenon can occur without ABS. This incident become worse when an emergency braking is applied either on wet or dry surfaces. Although ABS is crucial to prevent the collision, some vehicles still do not have ABS. This study is aimed to analyse the vehicle’s dynamic behaviour during emergency braking on wet and dry surface condition. The experimental vehicle model is a Malaysian sedan car namely Proton Persona. This instrumented car is equipped with sensors,video camera and data acquisition systems to determine the vehicle’s motion. In the experiment,when the vehicle reached a maximum speed of 60 km/h, the driver push the brake pedal firmly until the car stop. From the experimental results, the effect of emergency braking without ABS is clearly seen at the wheel speed. The tire locked up can be observed when emergency braking was applied on the wet surface. However, for the emergency braking on the dry surface, the tire decreased gradually. This finding shows that without ABS, the vehicle is unsafe and accident can occur. The experimental data from this study also can be used as a guideline to a researcher and manufacturer in the development of ABS and safety system of the vehicle

Published: July 2020

This study focuses on the aerodynamic performances of two vehicles by Dokuz Eylul University Solaris Solar Car Project Team. The first vehicle (S7) is a solar-powered vehicle that is designed for World Solar Challenge and the second (D9) is an electric vehicle which is designed for Tubitak EV Challenge. Both vehicles are manufactured using polymer composites and challenged in mentioned races. In this research, a formal optimisation technique based on computational fluid dynamics (CFD) is used to determine the efficient aerodynamic structures under various scenarios. Results clearly show that strategists of the racing teams should take intoaccount the aerodynamic structure of the racing car. Especially before the races which based on efficiency, the apex line is determined, and mirrors should be replaced by back view camera.
Normal Patterns of Histone H3K27 Methylation Require the Histone Variant H2A.Z inNeurospora crassa

Published: July 2020

AbstractNeurospora crassa contains a minimal Polycomb repression system, which provides rich opportunities to explore Polycomb-mediated repression across eukaryotes and enables genetic studies that can be difficult in plant and animal systems. Polycomb Repressive Complex 2 is a multi-subunit complex that deposits mono-, di-, and trimethyl groups on lysine 27 of histone H3, and trimethyl H3K27 is a molecular marker of transcriptionally repressed facultative heterochromatin. In mouse embryonic stem cells and multiple plant species, H2A.Z has been found to be colocalized with H3K27 methylation. H2A.Z is required for normal H3K27 methylation in these experimental systems, though the regulatory mechanisms are not well understood. We report here that Neurospora crassa mutants lacking H2A.Z or SWR-1, the ATP-dependent histone variant exchanger, exhibit a striking reduction in levels of H3K27 methylation. RNA-sequencing revealed downregulation of eed, encoding a subunit of PRC2, in an hH2Az mutant compared to wild type, and overexpression of EED in a ΔhH2Az;Δeed background restored most H3K27 methylation. Reduced eed expression leads to region-specific losses of H3K27 methylation, suggesting that differential dependence on EED concentration is critical for normal H3K27 methylation at certain regions in the genome.

Abstract
—Carbon dioxide (CO2) is one of the main volatile components of natural magmas, but estimation of its initial contents remains a challenge. Study of melt inclusions in minerals permits a direct estimation of the content of CO2 in the melts. For the precise determination of its content in melt inclusions, it is necessary to analyze the contents of CO2 both in glass and in the fluid daughter phase of the inclusions. In this work, we constructed a calibration dependence of the density of CO2 in the range 0.01–0.22 g/cm3 on the distance between its characteristic peaks in Raman spectra (Fermi diads). The accuracy of density determination is ±0.03 g/cm3. The calibration plot was used to estimate the density of CO2 in the gas phase of melt inclusions in magnesian olivine (Fo84.8-88.5) from basalts of the Karymskii Volcano, eastern Kamchatka. The estimated density was 0.03–0.21 g/cm3. Using these values, we have first evaluated the minimum initial content of CO2 in the parental magmas of the Karymskii Volcano, 0.45 wt.%. These data, along with the known initial content of water (~4.5 wt.%), indicate that the parental magmas began to crystallize at a pressure of at least 7 kbar (depth of &gt;25 km). To increase the reliability of the above method of estimation of the CO2 content in the gas phase of olivine-hosted melt inclusions, we propose to carry out preliminary experimental reheating of inclusions for the complete homogenization of the fluid phase and determination of the 3D size of melt inclusions. The performed study provides a reliable evaluation of the content of CO2 in parental magmas, the depth of crystallization, and the degree of magma degassing and permits a comparison of the compositions of magmatic fluids and high-temperature volcanic gases.
Melting and Parageneses of Global Subducting Water-Enriched Sediment in Closed and Open Systems: Experiment and Thermodynamic Modeling
Authors: Perchuk A.L. , Serdyuk A.A. , Zinovieva N.G. , Shur M.Yu. 
Published: July 2020

Abstract
—The phase relations and melting of subducting sediment were studied in two series of high-pressure experiments at 750– 900 °C and 2.9 GPa and by thermodynamic modeling. In the runs we used a chemical mixture corresponding in composition to global subducting sediment (GLOSS) but enriched in water (H2O = 15.52 wt.% as compared with 7.29 wt.% in GLOSS). The first series of runs was carried out in open capsules, and the second series was performed by the same procedure and at the same P–T–t parameters but in closed (welded) capsules. The products of the runs of both series showed agreement on the P–T conditions of melting and the presence of garnet, carbonate, kyanite, SiO2 phase, and phengite in the parageneses. However, the products of all runs in open capsules contain omphacite, including magmatic one, whereas the products of the runs in welded capsules lack it, except for those obtained in the subsolidus run (at 750 °C). The results of thermodynamic modeling for the composition of the experimental mixture (H2O–GLOSS) in the closed system are in agreement with the experimental data on the hydrous solidus and the stability of most minerals, showing a decrease in the content of omphacite as melt appears. This specific effect caused by the increased pressure of aqueous fluid in the closed system is observed in the welded capsules. Thermodynamic modeling for the H2O–GLOSS composition also shows that a complete decomposition of slab carbonates under “hot” subduction conditions is possible, but this result is not confirmed by our experimental data. Since the melting and mineral growth processes in subduction zones are controlled by migrating fluids and melts, it seems correct to rely on the results of runs in open capsules.

Abstract
—The exposures, structure, mineralogy, and composition of unusual sulfide-bearing troctolites from the Yoko-Dovyren layered intrusion in the northern Baikal area (Russia) are described in detail for the first time. The troctolite succession (referred to as the Konnikov Zone) is characterized by the presence of pegmatoid poikilite sulfides and sulfide dissemination with diverse PGE mineralization. The former are dominated by pyrrhotite–troilite products of exsolution of monosulfide solid solution (mss), and the latter is composed mostly of cubanite–chalcopyrite assemblages produced from an intermediate Ni–Cu–Fe solid solution (iss). The positive covariations between the contents of sulfur and chalcogens (Se, Te) along with the sublinear dependence of the Pd, Pt, Au, and Cu contents on the Te contents indicate a sulfide control of the distribution of these elements in troctolite cumulates. According to the sulfide-normalized contents of these elements in rocks, the average “100% sulfides” in the samples are subdivided into two groups: (1) strongly depleted in PGE, Au, Cu, and Te and (2) with 10–50-fold enrichment in them. This division is consistent with the morphological and mineralogical differences between the groups. Of genetic significance is the fact that the mss assemblages are somewhat poorer in PGE and Te than the primitive sulfides from the Dovyren basal zone, whereas the assemblages with predominant copper sulfides are significantly richer in these elements. This fact is confirmed by LA-ICP-MS data on the trace-element composition of the sulfide phases. The established specific features indicate a limited scale of fractionation of immiscible sulfides during the solidification of the troctolite cumulates. The formation of PGE- and Te-rich assemblages can be related to the course of crystallization of a sulfide precursor similar to the most primitive sulfide liquid. This is consistent with the known laws of crystallization of sulfide systems and explains the abnormally high S/Te ratios in pegmatoid troctolites enriched in mss products. Thus, sulfide melts act as an agent that transports precious metals and chalcogens in the troctolite cumulate area. This conclusion requires specification of the physical mechanisms and parameters (rheology, permeability, wettability by sulfides of different phases, etc.) of the cumulus medium favoring the spatial separation of a monosulfide solution and Cu-containing PGE-rich fractions with their subsequent infiltration and deposition at the boundaries of critical low permeability.

Published: July 2020

In order to establish a link between staple foods and prevalence of diabetes in populations, a preliminary survey aiming at diabetes frequencies has been executed with 16 diabetics. Glycaemia was evaluated in clinical laboratory and survey slip was used to collect information from patients. Results were analyzed at a threshold a = 0.05 with XLSTAT. Frequencies of higher glycaemia in diabetics for staple food were found in this ranking order: rice > sorghum > wheat > maize > millet > others. Such foods were eaten during a long period before diabetes symptoms. Patients of 36-40 years old were numerous in proportion (31.25%). Others cases of age groups go from 0.0% to 6.25% frequencies. Type 1 diabetes is found in sedentary persons and sellers with positive and significant correlation with glycaemia over 1.25 g/L (r =0.785-0.850) because of consummation of sorghum (r = 0.755) and wheat (r = 0.674) for social reason (r = 0.738). Type 2 diabetes is linked to economic reason (r = 0.688). Only cultivators have glycaemia between 1 g/L and 1.25 g/L. Contrary, sedentary, salaried and seller people showed glycaemia over 1.25 g/L. Consequently, significant correlations indicate wheat (r =0.851), rice (r = 0.815), sorghum (r = 0.753), maize (r = 0.655) and tea (r = 0.646); all are correlated social reasons (r = 0.825). Thus, many factors especially foods and life system contribute in releasing diabetes.

Abstract

Breast cancer (BC) is the most common cancer in women in Spain. During the COVID-19 pandemic caused by the SARS-CoV-2 virus, patients with BC still require timely treatment and follow-up; however, hospitals are overwhelmed with infected patients and, if exposed, patients with BC are at higher risk for infection and serious complications if infected. Thus, health care providers need to evaluate each BC treatment and in-hospital visit to minimize pandemic-associated risks while maintaining adequate treatment efficacy. Here we present a set of guidelines regarding available options for BC patient management and treatment by BC subtype in the context of the COVID-19 pandemic. Owing to the lack of evidence about COVID-19 infection, these recommendations are mainly based on expert opinion, medical organizations' and societies' recommendations, and some published evidence. We consider this a useful tool to facilitate medical decision making in this health crisis situation we are facing.

Implications for Practice
This work presents a set of guidelines regarding available options for breast cancer (BC) patient management and treatment by BC subtype in the context of the COVID-19 pandemic. Owing to the suddenness of this health crisis, specialists have to make decisions with little evidence at hand. Thus, these expert guidelines may be a useful tool to facilitate medical decision making in the context of a worldwide pandemic with no resources to spare.
