Authors: Rudahinyuka Samuel , Ngenzi Jean Claude , HongBing Li , Kubwarugira Gamaliel , Hongjie Xie , Ndihokubwayo Athanase
Published: May 2023

Civil engineering is moving to meet the needs of present and future generations through education, which is one of the ways to convey this dynamism. Thus, there is a vast literature on the contribution of higher education to the promotion of sustainable construction through the curricula provided by higher education institutions. However, there is an absence of studies that focus on the commitment of higher education institutions through their faculties’ objectives, which in turn drive the training curricula. This study, therefore, seeks to assess the commitment of nine Burundian universities involved in the training of construction engineers and architects, who are the main stakeholders in the construction industry in Burundi. Through qualitative and quantitative approaches, this study shows that Burundian universities involved in the training of construction engineers and architects are not well engaged in the promotion of sustainable construction. A reorientation of their faculties of civil engineering and architecture by redefining the objectives pursued both globally and specifically is desirable. This will generate a contribution of their part to sustainable development through the promotion of constructions inspired by the needs of the present generations without harming the needs of the future ones. The scarcity of studies and publications in this field in the Burundian context has limited this research.

Authors: Zhang Huimin , Jiang Yahua , Zhang Nan , Li Quan
Published: May 2023

Gas chromatography ion mobility spectrometry (GC-IMS) was used to detect the volatile organic compounds (VOCs) of Zheng5–5 sweet cherry fruits cultivar under three cultivation patterns [arched cover (PN), umbrella cover (SX), and open field (LD)]. VOCs were analyzed and compared using three-dimensional and two-dimensional top view visualization, fingerprint analysis, and principal component analysis (PCA). A total of 24 VOCs (including monomers and dimers) were detected in PN, SX, and LD, and 19 of them were finally identified, mainly alcohols, aldehydes, acids, esters, and ketones. The VOCs of PN, SX, and LD were similar but significantly different in content. The three compounds with the highest relative content were 2-hexen-1-olD, ethanol, and hexanalD, with ranges of 13.71% (LD) to 22.31% (PN), 13.02% (SX) to 21.27% (LD), and 8.22% (LD) to 16.66% (PN), respectively. Esters are the main components that form the sweet cherry fruit aroma, with a relative content of LD>PN>SX. According to the PCA, fruit samples of PN, SX, and LD can be clearly distinguished, indicating significant differences in VOCs under different cultivation modes. The GC-IMS visual plots of PN, SX, and LD agreed with the PCA results, and their combination was suitable for characterizing the VOCs of sweet cherry fruits under different cultivation patterns. This study can provide a reference for evaluating the flavor characteristics of sweet cherry fruits with different cultivation patterns.
A dunite fragment in meteorite Northwest Africa (NWA) 11421: A piece of the Moon’s mantle
Authors: Treiman Allan H. , Semprich Julia
Published: May 2023

A centimeter-sized fragment of dunite, the first recognized fragment of Moon mantle material, has been discovered in the lunar highlands breccia meteorite Northwest Africa (NWA) 11421. The dunite consists of 95% olivine (Fo83), with low-Ca and high-Ca pyroxenes, plagioclase, and chrome spinel. Mineral compositions vary little across the clast and are consistent with chemical equilibration. Mineral thermobarometry implies that the dunite equilibrated at 980 ± 20 °C and 0.4 ± 0.1 gigapascal (GPa) pressure. The pressure at the base of the Moon’s crust (density 2550 kg/m3) is 0.14–0.18 GPa, so the dunite equilibrated well into the Moon’s upper mantle. Assuming a mantle density of 3400 kg/m3, the dunite equilibrated at a depth of 88 ± 22 km. Its temperature and depth of equilibration are consistent with the calculated present-day selenotherm (i.e., lunar geotherm).

The dunite’s composition, calculated from mineral analyses and proportions, contains less Al, Ti, etc., than chondritic material, implying that it is of a differentiated mantle (including cumulates from a lunar magma ocean). The absence of phases containing P, Zr, etc., suggests minimal involvement of a KREEP component, and the low proportion of Ti suggests minimal interaction with late melt fractionates from a lunar magma ocean. The Mg/Fe ratio of the dunite (Fo83) is significantly lower than models of an overturned unmixed mantle would suggest, but is consistent with estimates of the bulk composition of the Moon’s mantle.

Authors: Lu Yu , Tang Zhen Huan , Wang Fei
Published: May 2023

The nonlinear dynamic model of a shared bearing bore-coaxial rotor system was established with nonlinear forces of the rolling bearings and squeeze film dampers considered, Cross coupling frequency was found in cross coupling vibration simulation. Numerical studies were conducted to reveal the mechanism of the coupling vibration for the shared bearing bore-coaxial rotor system. The coupling vibration characteristics and influencing factors of the shared bearing bore-coaxial rotor system were studied. The results show that the coupling vibration is featured by cross-excitation phenomenon and orbit which shows a “circle in circle” pattern. Besides, the angular stiffness of the shared bearing bore has great influences on the coupling vibration. However, the radial stiffness has almost no effect on the coupling vibration.
Research on microstructure and properties of Cu-0.41%Cr-0.20%Zr alloy after solution-aging treatment
Authors: Zhao Mei , Wang Ling , Li Meng , Cao Yufei
Published: May 2023

The phase analysis of Cu-0.41%Cr-0.20%Zr alloy treated by vacuum melting + solid solution + aging was carried out by means of SEM, TEM, EDXS and XRD. The results show that there are three phases in the alloy, namely the copper matrix phase, the chrome-rich phase and the zirconium-rich phase. The distribution of phase size is bimodal. The coarse phase size is microns scale, and the main components are elemental chromium and Cu5Zr, which are formed during the casting process and are not easy to dissolve in the subsequent aging process. The fine phase size is nanometer scale, and the composition is ordered bcc pure chromium and Cu5Zr. There is no chromium and zirconium intermediate phase. Under this condition, the volume fraction of precipitated phase is about 30 %. The heat treatment process can be further optimized by increasing the aging temperature, lengthening the aging time or adopting the second aging method.
Study on dynamical characteristics of cooling fluid in engine piston
Authors: Chen Xiaoqing
Published: May 2023

The cooling of engine piston is very important, and the fluid vibration characteristics of its internal cooling oil is the key to affect the heat transfer efficiency. In order to effectively ensure that the piston temperature will not be overloaded and avoid the reduction of sealing performance, a two-phase flow model in the piston cooling chamber is established in the paper. The flow field and heat transfer characteristics of the cooling oil are simulated by finite element method using FLUENT. In terms of model selection, VOF multiphase flow calculation and SST k-ω model are selected as turbulence model. The setting of boundary conditions combines the piston stroke characteristics of the hydraulic cylinder, so as to obtain accurate inlet parameters, and obtain the oil liquid phase proportion distribution, oil velocity field and the change law of convective heat transfer coefficient under different piston positions. The results show that the instantaneous ratio of cooling oil is closely related to the speed, and increasing the oil speed is an important means to improve the heat transfer performance. The multiphase flow model has high reliability, and there is no obvious difference between the average convective heat transfer coefficient obtained by the near-wall model method and the wall function method.
Design and research of single leg walking mechanism of quadruped robot
Authors: Hao Ruiqin , Guo Cheng , Han Zeguang , Han Yu
Published: May 2023

A new single-degree-of-freedom quadruped robot leg walking mechanism is proposed to solve the problems of more drive elements, more complex structure and control system in existing single-leg walking mechanism. The principle scheme and structure design of the leg walking mechanism of the quadruped robot are completed according to the requirements of the foot end trajectory curve and the actual motion characteristics. The dimensions of each rod of the single-leg crank rocker mechanism to meet the “inverted D-type” motion law at the E point on the linkage are solved by using the Burmester four-rod mechanism integrated graphical method. The kinematic equations at the P point of the foot end of the proposed scheme are derived by using the kinematic analysis. By ADAMS simulation, the displacement and velocity curves at the P point of the foot end can well meet the requirements of the foot end movement law. The present methodology can not only achieve the goal of less driving elements and more simple design in single-leg walking mechanism, and can well meet the requirements of walking stability and smoothness of motion.

Authors: Korendiy Vitaliy , Predko Rostyslav , Kotsiumbas Oleh , Lozynskyy Vasyl , Nazar Ihor , Ostashuk Mykola
Published: May 2023

Vibration-driven locomotion systems are widely used in various industries, particularly, in the form of capsule-type robots, wheeled platforms, worm-like units, etc. Because of the changeable operating conditions, such systems require continuous control of their kinematic and dynamic characteristics. The main purpose of the present paper is to define the optimal excitation conditions (forced frequencies and phase shifts) of a wheeled two-module vibration-driven robot equipped with two unbalanced rotors. The research methodology contains four stages: developing the robot’s dynamic diagram and mathematical model describing its motion; designing the robot’s simulation model in the MapleSim software; numerical modeling of the system locomotion conditions in the Mathematica software; simulating the system dynamic behavior in the MapleSim software. The obtained results show the time dependencies of the system’s kinematic characteristics at different phase shift angles of the unbalanced rotors. The major scientific novelty of this paper consists in substantiating the possibilities of adjusting the system’s operational parameters in accordance with the changeable technological requirements by means of changing the phase shift angles of the unbalanced rotors. The proposed ideas and obtained results can be used while developing new designs of robots based on the two-module vibration-driven systems and while improving the control systems for adjusting their performance in accordance with the changeable operational conditions.

Authors: MUTLU Doğukan , SEÇME Mücahit , ARSLAN Şevki
Published: May 2023

The high mortality rate of Glioblastoma multiforme (GBM) patients is partly due to the invasive behavior of the tumor cells. Given the increased resistance to conventional therapies of invasive cells after surgical operations, current treatments are ineffective. Therefore, understanding the mechanisms of GBM cell invasion is critical for the development of successful therapeutic approaches. Natural small molecules and metabolites are widely used as chemotherapeutic and adjuvant agents in cancer treatments because they have strong anticancer properties and minimal side effects. Alpha-lipoic acid (ALA) is an antioxidant that has been found to reduce the level of ROS and increase GPx activity in cancer patients. In this study, we analyzed the in-vitro cytotoxic potential and apoptotic effect in A172 and U373 cells in the presence of various concentrations (7.8-500 µM) of ALA. We also investigated scratch assay in both cell lines. The ALA inhibited cell viability of A172 and U373 cells at 48h. In addition, Bax mRNA expression was significantly increased in response to ALA for A172 cells. Furthermore, the BCL-2 level was decreased in A172 cells with ALA after 48h. Caspase 3 and 9 mRNA expressions were increased in ALA treated U373 cell line. In summary, we found that ALA inhibits cell growth and causes apoptosis in A172 and U373 glioblastoma cells.

Authors: BULUT Sadullah , YİĞİDER Muhammed
Published: May 2023

İn this study, we present a method in order to get initial value fractional differential equations with artificial neural networks. On the basis of the function approach of feedforward neural networks, this method is a general method that is written in an implicit analytical form and results in the creation of a differentiable solution. The first part of the created trial solution which is stated as the sum of the two parts, with no controllable parameters, gives the initial conditions. The second part, unaffected by the initial conditions, consists of a feedforward neural network with controllable parameters (weights). The applicability of this approach is demonstrated in systems of both fractional single ODEs and fractional coupled ODEs.
Exaggerated arsenic removal efficiency and pH adaptability by adsorption using monodispersed porous pinecone-like magnesium hydroxide
Authors: Lin Qiwei , Chen Wendan , Lin Fangjie , Zhu Hu , Wang Xuesong
Published: May 2023

Arsenic compounds are classified as Class I carcinogens due to their high toxicity to the organism. Also, they are easily accumulated in water bodies, and both H2AsO4− and HAsO42− are present simultaneously and convert to each other in a wide pH range. Based on the strategy of simultaneous removal of protons to immobilize AsO43−, a monodispersed porous pinecone-like Mg(OH)2 (PLMH) was prepared via a facile and environmentally friendly ultrasound-assisted precipitation route for deep As(V) removal. The PLMH presents a porous and stable framework structure formed by crossed lamellae, and the As(V) solution can be completely immersed inside, which gives a ‘surface effect’ inside the microsphere and makes the As(V) capture performance much higher than the general adsorbents by the removal of protons to immobilize AsO43−. In addition, the PLMH has an extremely wide pH applicability range (pH 3–12), special pH effects, and symmetry phenomena. These performances indicate that the PLMH can be a good candidate for the treatment of real arsenic industrial wastewater.

Authors: Shahzadi Iram , Mubarak Shafaq , Farooq Ariba , Hussain Naqi
Published: May 2023

Solid waste management (SWM) is one of the biggest concerns of society and agricultural waste is generated in vast amounts. In this study removal of Cu and Cr from wastewater using chemically modified apple peels was studied by following batch sorption experiments. Effects of metal concentration, adsorbent dose, pH, temperature and contact duration on the adsorption of Cu & Cr were investigated by using atomic adsorption spectrophotometer (AAS). SEM & EDX analysis of the adsorbents were recorded to study the morphology of the prepared adsorbents. Qmax value of apple peels is 25 for Cr and 22 for Cu, while for apple peel charcoal it is 33 for Cr and 47 for Cu, for treated apple peels Qmax is 50 for Cr and 52 for Cu adsorption. The data was processed using pseudo first, second order kinetic and intraparticle diffusion. Results depicted that the calculated adsorption capacities (qecal) were found to be close to the experimental values (qecal) by following pseudo-second-order kinetics. The applicability of the Langmuir and Freundlich adsorption isotherms was tested. Results showed that the Langmuir model is best fitted on adsorption data because regression factor R2 values are good for the Langmuir model.

Authors: Lopera Valentina , Pereañez Jaime Andrés , Amariles Pedro Jose
Published: May 2023

Background:

A list of drugs that can induce takotsubo cardiomyopathy (TCM) was published
in 2011 and 2016. The aim of the present review was to update this list.

Methods:

Similar to the 2011 and 2016 reviews, from April 2015 to May 2022 case reports of druginduced
TCM were identified by a comprehensive search in Medline/PubMed database. The search
terms were: takotsubo cardiomyopathy, tako-tsubo cardiomyopathy, stress cardiomyopathy, transientleft-
ventricular ballooning syndrome, apical ballooning syndrome, ampulla cardiomyopathy OR broken
heart syndrome; together with “iatrogenic”, “induced by” OR “drug-induced”. Registers published in
English or Spanish, in humans, and with full texts were retrieved. Articles that recognized any drug
associated with the development of TCM were selected.

Results:

Overall, 184 manuscripts were identified by the search. A total of 39 articles were included
after an exhaustive revision. Eighteen drugs as possible triggers of TCM were identified in the current
update. Of them, 3 (16.7%) have been previously identified, and 15 (83.3%) are different from the previous
reports. Thus, the list of drugs as possible triggers of TCM updated in 2022 includes 72 drugs.

Conclusion:

There are new case reports that link drugs with the development of TCM. The current list
is principally made up of drugs that generate sympathetic overstimulation. However, some of the listed
drugs do not have a clear link with sympathetic activation.

Authors: Al-Asmar Ayah A. , Sabrah Alaa H.A. , Ismail Noor H. , Abd-Raheam Islam M. , Oweis Yara G.
Published: May 2023

Objective:

The present study aims to investigate the reasons for the immediate failure of direct anterior and posterior resin composite restorations placed by dental students.

Methods:

A cross-sectional study on resin composite restorations placed by fourth- and fifth-year dental students (n=436). Variables included in the study were; the operative field isolation method, the time needed to complete the restoration after cavity preparation to polishing and finishing, and the plaque index of the patient. Restoration class distribution according to the type of tooth and cavity classification was examined and recorded. Restorations were clinically evaluated immediately after placement. It involved the assessment of the restoration’s mobility, marginal discoloration, and lack of anatomy.

Results:

A total of 233 direct anterior and posterior resin composite restorations which were placed by 127 students were diagnosed as failed restorations. The mode of failure was distributed as mobility/debonding (61.80%), marginal discoloration (29.18%), and lack of anatomy (9.02%). Cl III restorations demonstrated the highest failure on tooth type and cavity classification (30%), followed by Cl II restorations in molars (18.45%). Failure-associated factors were proper restoration manipulation, field isolation, and patients’ plaque index.

Conclusion:

In the current study, the most frequent reason for the immediate failure of resin composite restorations was the quick application of the restoration either as the only associated factor or coupled with other failure-associated factors. Failure to maintain proper field isolation and the poor oral hygiene of the patient were the other two failure-associated factors.
Defect Identification Method of Cable Termination based on Improved
Gramian Angular Field and ResNet
Authors: Sun Chuanming , Wu Guangning , Xin Dongli , Liu Kai , Gao Bo , Gao Guoqiang
Published: May 2023

Background:

This paper proposes a defect identification method for vehicle-mounted
cable terminals in electric multiple units (EMUs) based on the improved Graham angle field and
residual network to address the issue of low recognition accuracy caused by the lack of partial discharge
(PD) and identification data for Ethylene Propylene Rubber (EPR) cable terminal defects.

Methods:

The improved Gramian angular field (IGAF) characteristic transformation method was
used to transform the PD one-dimensional time-series signal into a two-dimensional one after cable
terminals with four common insulation defects were constructed, and a PD detection platform was
built. Finally, an anti-aliasing downsampling module and attention mechanism were added to the
residual network ResNet101 model. The Center loss and Softmax loss functions were integrated to
increase accuracy for training and recognition classification. Topological feature images improved
the distinguishability of defect categories.

Results:

The test results showed that the diagnostic method has an accuracy rate of 97.3% for identifying
PD at the cable terminal.

Conclusion:

The proposed diagnosis model has higher recognition accuracy and better balance than
other conventional fault diagnosis methods, making it suitable for diagnosing high-voltage cable
faults in EMU trains.

Published: May 2023

Indonesia is one of the countries infected by the Coronavirus Disease 2019 (COVID-19) pandemic, which is caused by acute respiratory syndrome virus 2 (SARS-CoV-2). At the end of March 2020, the provincial government of Bali appointed Udayana University Hospital to handle COVID-19 patients because the province has experienced an increase in the number of positive cases. In September 2020, COVID-19 cases in Bali increased by more than 100%, resulting in a higher volume and content of hazardous liquid waste. Furthermore, hazardous liquid waste is the residue of activities that contain substances that can pollute and damage the environment and health, necessitating more efforts in managing the processing of hazardous wastewater produced by the hospital. Based on the background above, this study developed and applied an Internet of Things (IoT) based monitoring system to the Wastewater Treatment Plant (WWTP) in Udayana University Hospital. In principle, the IoT system can be used as a real-time monitoring tool and minimizes direct contact activities of officers’ WWTP sites. Moreover, the Liquid Film Aerator (LFA) was applied to improve the efficiency of WWTP. The developed IoT system successfully monitors pH, DO, and real-time temperature, and the monitoring results were presented in a web-based user interface. The result shows better power usage efficiency than conventional aeration. Furthermore, conventional aeration with a root blower requires 619.8 watts to produce 1 mg/L of DO, while LFA only requires 273.2 watts. The developed systems can be applied to other hospitals or similar wastewater plants that handle COVID-19 cases.

Authors: Rediasti Fransisca Natania Karina , Jayadi Rachmad , Triatmodjo Bambang
Published: May 2023

The construction of the Meninting Reservoir was planned with the objective of meeting the irrigation and domestic water demands on Lombok Island. It served as a multipurpose reservoir, with a maximum storage volume of 12.18 million m³, mainly for supplying irrigation and domestic water. The reservoir had considerable potential for water availability, which could be used to supply water to the South Lombok region with limited water availability but had agricultural land potential. Therefore, this study aimed to evaluate the potential of Meninting Reservoir water availability and its optimum utilization for irrigation and domestic purposes. The irrigation water demand for 1,559.29 ha and domestic water demand of 150 ls-1 was fulfilled by Meninting Reservoir. Water availability in this Reservoir was estimated with the F.J. Mock method of rainfall-runoff model using 25 years of daily rainfall data from Gunung Sari and Sesaot rain gauge stations. The calibration process of the rainfall-runoff parameters models employed observed discharge data from the Aiknyet water level gauge station. The formula for optimizing reservoir water release was prepared using the linear programming method based on operational water level limits, inflow discharge, irrigation, and non-irrigation water requirements, including domestic water. The optimal average annual cropping intensity was 203.96%, 215.87%, and 241.41% for dry, normal, and wet years, respectively. The service reliability of irrigation and domestic water demands reached 100% for all inflow discharge conditions. The k-factor value met the minimum limit of 0.70 and 0.85 for irrigation and domestic water demands, respectively.

Degustar un cheesecake en Do Mayor: el placer musical y su función biológica adaptativa

Published: May 2023

¿Por qué nos gusta la música? Los seres humanos disfrutamos de escuchar música, tanto que inundamos nuestras actividades diarias con esta práctica. Este fenómeno parece ser algo que se extiende en todo el mundo, aunque no todas las culturas tengan una misma concepción sobre la música. Desde una perspectiva evolutiva, si la música es tan importante para la especie y ha permanecido a lo largo de todos estos miles de años, alguna importancia biológica adaptativa debería de tener. No obstante, ciertos autores sugieren que la música no es más que un subproducto de la evolución sin una función relevante para la reproducción o la sobrevivencia de la especie, por lo que únicamente sirve para deleitar al oído, como si fuera un cheesecake auditivo (Pinker, 1997). ¿Realmente la música no es trascendental para la vida humana? Eso es lo que exploraremos en este artículo.

Las interacciones ecológicas que ocurren en los diferentes ecosistemas permiten un flujo de energía y nutrientes. Pueden ser intraespecíficas o interespecíficas y categorizarse en mutualismos, cuando las especies involucradas se ven beneficiadas; o en antagonismos, cuando existen efectos negativos derivados de su interacción. Existen plantas parásitas con capacidad de establecerse sobre otras plantas para nutrirse y desarrollarse, como los muérdagos, que son un grupo de plantas que tienen un impacto negativo en las especies forestales y arbolado urbano, ya que pueden afectar su desarrollo. A pesar de lo anterior, también puede beneficiar a otros organismos como aves o mamíferos al proveerles alimento, refugio o sitios de anidación. El presente trabajo describe casos y características de estas interacciones.

Reconocer las diferencias de género en la fuerza laboral es crucial para garantizar la seguridad y salud de los trabajadores. Estas diferencias implican la necesidad de comprender los peligros, riesgos y aplicar soluciones efectivas (Organización Internacional del Trabajo, 2021). Aunque se han logrado avances, la oit destaca la necesidad de hacer más en este aspecto.
Las mujeres y hombres enfrentan riesgos físicos y psicológicos diferentes debido a los trabajos que realizan, los roles que desempeñan y las expectativas y responsabilidades asociadas. Esto requiere medidas de control y prevención específicas. Para lograr políticas y estrategias de seguridad y salud en el trabajo efectivas para ambos géneros, es fundamental contar con información detallada sobre la relación entre la salud laboral y los roles de género (oit, 2021).
Este artículo tiene como objetivo ofrecer una visión realista de la salud laboral de las mujeres, abordando las diferencias de género, las condiciones de trabajo y los riesgos asociados, entre otros temas relevantes. Tanto las desigualdades de género como otros factores mencionados deben ser considerados al desarrollar estrategias de prevención y políticas de seguridad y salud laboral para las mujeres.

Interspecific interactions between vertebrates of different groups are common but also complex and of great importance for community structure. In particular, predation, considered a trophic interaction, plays a significant role in food webs structure and selective effects on prey in natural ecosystems. In this paper we provide new information on the trophic relationship between birds and herpetofauna (reptiles and amphibians) in the complex and biodiverse Usumacinta river basin, through 10 observations recorded between 2012 and 2021. The observations show interactions for feeding purposes of eight bird species, including herons (Tigrisoma mexicanum), jays (Psilorhinus morio), raptors (Caracara cheriway,  Pseudastur albicollis, Harpagus bidentatus, Buteo plagiatus), puffbirds (Malacoptila panamensis), and ducks (Dendrocygna autumnalis), with snakes (Coniophanes quinquevittatus), turtles (Chelydra rossignonii, Trachemys venusta), lizards (Iguana iguana, Sceloporus serrifer), crocodiles (Crocodylus moreletii), and frogs (Smilisca baudinii).
Disfuncionalidades do modelo institucional liberal: juristocracia e backlash
Authors: Souza Britto Melina Carla de , Barbosa Claudia Maria
Published: May 2023

O constitucionalismo contemporâneo promove a expansão e a abertura do texto constitucional, ampliando a discricionariedade do Judiciário, tornando insuficiente a clássica separação de poderes, essência do constitucionalismo liberal. A juristocracia e o backlash são fenômenos associados à expansão do Judiciário e à crise do constitucionalismo liberal, sendo indicativos da insuficiência do modelo institucional liberal adotado pelo constitucionalismo contemporâneo. Utiliza-se neste artigo o método dedutivo e a técnica de pesquisa documental indireta, notadamente a bibliográfica e jurisprudencial. Conclui-se que a juristocracia e o backlash são expressões indicativas da fragilidade do arranjo institucional liberal e recolocam em discussão a tradicional tensão liberal entre contramajoritarismo e majoritarismo (entre constitucionalismo e democracia), fazendo emergir a necessidade de novos arranjos institucionais.
Fabrication of Hybrid Engine Vehicle

Abstract: A hybrid vehicle uses two or more distinct types of power, such as internal combustion engine + electric motor, e.g. in diesel-electric trains using diesel engines and electricity from overhead lines, and submarines that use diesels when surfaced and batteries when submerged. Other means to store energy include pressurized fluid, in hydraulic hybrids. A water-fuelled car is an automobile that hypothetically derives its energy directly from water. Water-fuelled cars have been the subject of numerous international patents, newspaper and popular science magazine articles, local television news coverage, and websites. The claims for these devices have been found to be pseudoscience and some were found to be tied to investment frauds.[1] These vehicles may be claimed to produce fuel from water on board with no other energy input, or may be a hybrid claiming to derive some of its energy from water in addition to a conventional source (such as gasoline). Water is fully oxidized hydrogen. Hydrogen itself is a high-energy, flammable substance, but its useful energy is released when water is formed. Water will not burn. The process of electrolysis can split water into hydrogen and oxygen, but it takes as much energy to take apart a water molecule as was released when the hydrogen was oxidized to form water. In fact, some energy would be lost in converting water to hydrogen and then burning the hydrogen because some waste heat would always be produced in the conversions. Releasing chemical energy from water, in excess or in equal proportion to the energy required to facilitate such production, would therefore violate the first or second law of thermodynamics.

Abstract: The intensity of precipitation plays a crucial role in hydraulic engineering when creating hydraulic structures and evaluating their impact. To design hydraulic projects such as drainage networks, bridges, and road culverts, Intensity-DurationFrequency (IDF) curves are used. These curves are heavily influenced by project planning, design, and operation in the field of water resources engineering and are also used in various flood structures. In this study, the frequency of rainfall intensity duration was determined in Kamti, Khari, catchments, Nagpur Maharashtra, from 1996 to 2019. Three different frequency analysis methods, including log-normal, Gumbel, and log-Pearson type III distribution, were applied to fit the corresponding curves. Analyzing the precipitation data is of great importance in this field..

Objectives: study aims to provide a descriptive overview about the magnitude and frequency of dispensing the unprescribed antibiotics UABs. It furthermore aims, to specify the most dispensed UAB types, the most common infections, signs and symptoms that require dispensing the UABs in community pharmacies of Duhok city and its districts. 
Methods: A cross sectional cohort study had been conducted from September to October 2022, private community pharmacies of Duhok province were included in this study. A standardized questionnaire platform was utilized to complete the survey, it included 2 sections, the first of which was related to demographic data and the second part included details of the dispensing unprescribed antibiotics UABs like: what are the most common dispensed UABs, what are the most common illness and symptoms of patients who require dispensing UABs. Results: One hundred fifty pharmacies have been included in this study. The majorities were from Duhok city 46%, and Zakho 28.7%. The prevalence of dispensing UABs was 100%, the three most common dispensed UABs were Amoxicillin 77%, followed by azithromycin 16% and cefixime 7%. The most infections and conditions requiring dispensing UABs were tonsilitis (69.3%), followed by flu and common cold (58.7%), and lower respiratory tract infection (48.7%). Conclusion: This study concluded that dispensing UABs is a frequent practice in Duhok community pharmacies. Viruses are the most common cause of upper respiratory tract infections; hence, antibiotics must be avoided and OTC medicines should be encouraged to alleviate the symptoms. Continuing medical education through training pharmacists on dispensing antibiotics by adhering to the regulations of antibiotic stewardship is crucial.

Published: May 2023

The human desire to engage in politics is an integral part of their nature. However, in order to conduct politics well and in line with desired goals, a strong understanding of politics is required. Therefore, it is important to understand the concept of politics in Islam through modernist figures such as Hamka, who created a new conception of Islam and politics. The purpose of this research is to analyze Hamka's views on the rules of politics in Islam and the goals of Islamic politics. This research is the result of a qualitative literature study using Hamka's work entitled "Lembaga Hidup" as the main source. The results of the study show that, according to Hamka, the rules of Islamic politics should be based on natural law, moral law, and the law of human nature, and serve the interests of individuals, not groups or the state. The purpose of Islamic politics is to create justice for society, provide individual freedom, and create unity, brotherhood, and equality among human beings.Abstrak: Keinginan manusia untuk berpolitik adalah bagian integral dari kodrat kemanusiaannya. Namun, untuk menjalankan politik dengan baik dan sejalan dengan tujuan yang diinginkan, diperlukan pemahaman yang kuat tentang perpolitikan. Oleh karena itu, penting untuk memahami konsep perpolitikan dalam Islam melalui tokoh modernis seperti Hamka, yang menciptakan konsepsi baru tentang Islam dan politik. Tujuan penelitian ini adalah untuk menganalisis pandangan Hamka tentang aturan perpolitikan dalam Islam serta tujuan politik Islam. Penelitian ini merupakan hasil kajian kepustakaan menggunakan metode kualitatif dengan sumber utama yaitu karya Hamka yang berjudul "Lembaga Hidup. Hasil penelitian menunjukkan bahwa menurut Hamka, aturan perpolitikan Islam harus didasarkan pada hukum alam, hukum moral, dan hukum fitrah manusia serta melayani kepentingan individu, bukan kepentingan kelompok atau negara. Tujuan dari politik Islam adalah untuk menciptakan keadilan bagi masyarakat, memberikan kebebasan individu, serta menciptakan persatuan, persaudaraan, dan kesetaraan antar-manusia.
Climate and environmental risk factors in the market risk field: An extended model
Authors: Bonollo Michele , Menegon Antonio , Terzi Luigi
Published: May 2023

The extension of the risk management models to the broad sustainability concept is an open issue in both the academic and financial communities. The current state of the art for the risk measurement models is not satisfactory. There are many weaknesses in the data feasibility and the debate about what the new models should measure is still open. We propose a model that aims to improve the existing market risk models by capturing the sustainability risk sources. The starting point is the incremental risk charge (IRC) model, namely a 1 year 99.9 percent value at risk that covers default and migration risk. We extend the traditional model by defining the environmental incremental risk charge (E-IRC), with two enhancements: 1) by some data analysis and statistical techniques we introduce some new environmental, social, and governance (ESG) risk factors to better explain the portfolio behavior; 2) we adjust the default probabilities provided by the rating agencies by combining the green premium (lower spread) observed in the markets with the available ESG score for each obligor. The new model was tested on a real portfolio by a Montecarlo engine. The model does not affect too much the existing IRC results, so allowing continuity in the reporting process. The main advantage of E-IRC is the availability of a more effective risk decomposition process, where the ESG contributions can be properly highlighted.
