Authors: Abdullah Mohammad , Triwikantoro Triwikantoro , Umamah Chairatul , Andi Herman Jufri
Published: June 2021

In this research ZrO2 has been synthesized from Kereng Pangi zircon sand in Central Kalimantan through alkali fusion-coprecipitation method. Firstly, zircon sand (ZrSiO4) was purified to reduce impurities by magnetic separation, cleaned using an ultrasonic cleaner, soaked/leached with HCl 2 M for 12 hours and leached with HCl at 60 ºC for 3 hours. Secondly, alkali fusion was done with KOH as an alkali. This product was then washed by water and dried before leached with HCl 30% at 90 ºC for 30 minutes to precipitate and seperate Silica from Zircon. ZrO2 filtrate (ZrOCl2) precipitated with NH4OH at pH 4, pH 7, and pH 10 forms Zr(OH)4 gel. Zr(OH)4 gel was dried and characterized by DTA-TGA, which was then followed by calcination based on DTA TGA results at temperature ranges of 550 ºC - 700 ºC to produce ZrO2. XRD results show that single tetragonal phase of ZrO2 is formed in all variations of pH precipitation and calcination temperature. An analysis using MAUD software show that crystal size reduces as the increase in precipitation of pH. The crystal size results are 110 nm, 66 nm and 48 nm at pH 4, pH 7 dan pH 10 at 700 ºC, respectively. Moreover, XRF results show that ZrO2 with purity is at around 95.8 % at pH 4 and 96.3 % at pH 7 and pH 10.

The lack of public concern for washing hands during the Covid-19 pandemic, the authors designed an automatic sink using an arduino-based HC-SR04 ultrasound sensor to attract the public's interest. By making automatic sink technology using the HC-SR04 ultrasound sensor based on Arduino for use in hand washing by the community. This study uses experimental research that examines the effect of automatic washbasin with people's behavior in washing hands. By testing the use of water in 20 seconds, 43 people can use it in one day, and soap can be used by 6 people in one day in 5 seconds. The automatic sink using the HC-SR04 ultrasound sensor based arduino can be used with a distance that is made less than 15cm designed to be practical and sterile because it is used that does not touch faucets or soap. The conclusion of the study is that if there is an object that approaches the ultrasound sensor within a distance of less than 15cm, the water pump will be active for 20 seconds or the soap pump for 5 seconds will automatically come out. And it will run out if used for 934 seconds in 1 liter gallon or 46 people a day and the use of soap for 5 seconds will run out approximately 6 people in one day.
THE USE OF (Mg0.9Zn0.1)TiO3+2wt.% Bi2O3 CERAMICS AS A DIELECTRIC RESONATOR OSCILLATOR MATERIAL AND CHARACTERISATION OF STRUCTURE, MICROSTRUCTURE, AND DENSITY
Authors: Kadarosman Afandy , Ermawati Frida Ulfah
Published: June 2021

Magnesium titanate (MgTiO3)-based ceramics have the potential for use in the telecommunications industry at microwave frequencies, including as a resonator in dielectric resonator oscillator (DRO) circuit. This research is intended to study the application of (Mg0.9Z0.1)TiO3+2wt.% Bi2O3 (abbreviated MZT01-2) ceramics as DRO material and characterize the structure, microstructure, and bulk density. Fabrication was carried out by ball milling between (Mg0.9Z0.1)TiO3 crystalline powder and 2wt.% Bi2O3 powder. The milled powder was compacted at certain pressure using a die press to become pellets. All pellets were sintered at 1000, 1100, 1200°C for 4 h to obtain ceramics. The structural characterization using XRD showed that the three ceramics contained the main MgTiO3 phase, each 93.63, 93.83, and 90.78% molar, the rest was the MgTi2O5 phase. The increase in sinter temperature causes the lattice parameter and the unit cell volume to decrease. The Archimedes bulk density was 2.928; 2.832 and 2.736 g/cm3. The microstructure is solid surfaces with a grain diameter of 1.9-2.3 μm accompanied by pores. As DRO materials, the three ceramics exhibited a resonant frequency at 5.11, 5.08, and 5.12 GHz which shows that the ceramics can be applied as DRO materials at microwave frequencies. The sinter temperature variation tends not to affect the resonant frequency position.

Authors: Galiullina Liana Ildarovna , Wright Eleanor
Published: June 2021

The article deals with the problem of the reverse influence of the Internet and chat communication on the spoken language based on the "Language of scum" in the Russian-speaking Internet. Today, this problem is relevant, since the development of the Internet has contributed to the widespread use of slang among the younger generation. The Internet today is a source of information. But the speed and availability of communication between users made it possible to use the Internet not only as a cognitive tool, but also as a means of communication and entertainment. And virtual communication, which arose due to the rapid development of the network, gave rise to a special language - the language of virtual communication. The numerous chats, open forums and personal pages created on the network are the main ways of communication among young people. Over the years, a special language has developed in the programs - slang, the so-called language of Internet communication, in which users communicate with each other. And every day he actively penetrates into our daily life. This study is a kind of appeal not only for adolescents, but also for the adult population. I would like people to think about the fact that we need to protect our language and not succumb to the influence of slang when communicating on social networks. The practical significance of the work lies in the fact that the results of this study will be useful to students in order to preserve their native language.

Published: June 2021

The Holy Quran is an infinite ocean which benefits everyone to the extent of their scientific ability and scope of existence. This divine book would not be only a text; rather, its interpretation and explanation open various chapters of science, wisdom, and knowledge to human beings. Therefore, the only way to enter this gate of science, wisdom, and knowledge is its interpretation. Up to now, various approaches and interpretive books have been emerged to decipher and decode this divine blessing, but non of them has been perfect, and each is considered as a defect. Therefore, the best and the safest way would be to refer to a new definition of the “comprehensive” interpretation. In the following research paper, we will try to express the need and necessity of applying a comprehensive approach to the interpretation of the Holy Quran, providing a new definition of it in the description of the divine words.

Studying the Types, Bases and Features of Sale from the Perspective of Islamic Jurists
Authors: Jafarzadeh Morad , Razmi Seyed Mohsen , Kazemi Golvardi Mohammad Reza
Published: June 2021

Sale is known as one of the most widely used words in Islamic jurisprudence. Islamic jurists have each defined the nature, bases and types of sale as one of the specific and important Islamic contracts. Regarding sale, it should be mentioned that in some definitions, the early Imami jurists considered its nature as the exchange of two properties, while the famous Islamic jurists consider its nature as the demand and acceptance, which makes the object of sale the property of the customer and regards the price as the property of the seller. Another point is that, in the definitions of late and contemporary Imami jurists, there is a kind of semantic alteration in the interpretation of sale. From the view point of Islamic jurists, it seems that the elements of possession and ownership in the sale are concepts with wide conceptual scopes, and this is the superiority and distinction of Imami jurists over other jurists regarding the truth of sale. On the other hand, from the point of view of Islamic jurists, there are different types of sale, the most important of which are strict sale, contractual sale, absent sale, harmful sale, credit sale, general sale, deferred sale, gifted (mohabati) sale, debt sale, Morabahe (a sale based on a fixed price), etc. On the other hand, the bases of sale from the perspective of Islamic jurists are: demand and acceptance, buyer and seller, property sold, and price in the sale contract. Also, the features of sale from the point of view of jurists are: the ownership of the sale, the exchange of the sale, the objectivity of the property, the necessity of the sale contract. The research methodology in this paper is descriptive-analytical using the library method.

This study it was aimed to examine the emotional intelligence and personality traits of the students who study in different departments of the Faculty of Sport Sciences at Ege University and actively do sports in different sports branches. In total 549 students participated in the study voluntarily. To evaluate the variables of the study, the Schutte Emotional Intelligence Scale developed by Schutte et al. (1998) and adapted into Turkish by Tatar et al. (2011), and to evaluate personality traits, five-factor personality inventory developed by Somer, Tatar, and Korkmaz (2004) and whose short form was validated and reliable by Tatar (2005) were used. In this study, the data set was SPSS 22.0, and it was completed by using frequency tables, reliability analysis, independent sample t-test, one-way variance analysis, Tukey test, and correlation analysis in analyzes. There is both a significant (p<0.05) and an insignificant (p>0.05) difference between emotional intelligence and subscales of personality according to the department, type of education, average grade, class, gender, age and branches. There is no significant difference between emotional intelligence and personality (p> 0.05). They are independent of each other. As a result, as the concepts of emotional intelligence and personality affect individuals deeply, the main purpose of this study is to find the necessary information with the necessary studies to better understand the students in the sports science faculty. This study is to measure the emotional intelligence and personality traits of the students studying at the Faculty of Sport Sciences at Ege University and to examine the relationship between emotional intelligence and personality. We think that it is an important study as it will make a serious contribution to the studies by repeating similar studies and applying them to large sample groups in different fields in different universities and different branches.

Authors study the issues of providing the suspect and the accused with the right for defense in criminal proceedings through the prism of the provisions enshrined in international normative legal acts and the Constitution of the Russian Federation. The relevance of this article is substantiated by the authors by the fact that the consideration of the problems of the procedural status of the suspect and the accused in the criminal case should start with this basic provision of the principle of criminal proceedings, such as ensuring the right for protection to the suspect and the accused under article 16 of the Criminal Procedure Code of the Russian Federation. In the context of the modern legal state and the requirements of the Constitution of the Russian Federation, which establishes the basic rights and freedoms of the person and the citizen. The solution to this problem becomes extremely important in the field of criminal justice, which is inevitably associated with the restriction of the constitutional rights of the individual within the limits allowed by law. In this regard, the problems of ensuring the right of the suspect and the accused to a defense require special attention. Based on the results obtained, the authors conclude that compliance with the guarantees of the right to defense of suspects and accused persons has a significant impact on the domestic and foreign policy image of the Russian Federation, being directly proportional to the legal insinuations of international organizations and attempts to influence the Russian legal system.

Published: June 2021

A special place belongs to the historical thought of the late 19th - early 20th centuries in the spiritual heritage of the Tatar people. In a short time, Tatar historians have achieved significant results in the reconstruction and study of the national past. Their successes were appreciated by Russian and European scholars and orientalists, and their unconditional leadership among other Turkic Muslims was generally recognized. The works by Sh. Mardzhani, R. Fakhrutdinov, G. Akhmarov, H. Atlasi, G. Gubaidullin are being republished today and are returned to the reader. Their work is being successfully studied, but there are no works where the formation and development of Tatar historical science at the end of the 19th - beginning of the 20th centuries would be considered specifically. A systematized study of the historical thought of the Tatars during the Jadid period, the determination of the characteristics, trends, and the directions of its development remains an urgent task of modern science. This scientific article examines the features of Russian-Tatar relation coverage by Tatar historians of the late 19th - early 20th centuries, reveals the information and analytical activities of censorship and its special attention to historical writings, contains an overview of little-known sources - popular editions and publications in time-based press, dated to the centenary of The Patriotic War of 1812 and the 300th anniversary of the House of Romanov, the authors of which, showing the commonality of the historical fate of Russians and Tatars, substantiated the thesis of "equal rights in a common Fatherland". The obtained analytical results are very effective in increasing the level of education of educators in this field.

Cosmetic surgical procedures on the vulva and vagina - an overview
Authors: Panicker Rajesh , Pandurangan Thunga
Published: June 2021

Cosmetic surgery is defined as any procedure involving a change in the appearance or aesthetics of a normal anatomy where there are no congenital or acquired pathologies. The procedures that can be included under female cosmetic genital surgery are the following: reduction labiaplasty, vaginoplasty, hymenoplasty, “G-Spot amplification”, and miscellaneous. Those who support these procedures could argue that women undergo such procedures as a matter of choice, whereas those opposed could argue that this choice is made because of society’s fascination with physical appearance and feeling young. Prima facie these procedures appear to contradict the Hippocratic principle of “primum non nocere”. There has been an increase in the marketing and conduct of the above mentioned procedures. Practitioners need to be both sceptical and cautious while performing these surgeries. Patients requesting them need to be counseled regarding the lack of data supporting their efficacy, and the potential complications of the procedures.

Neste trabalho foram utilizadas três cepas diferentes da levedura YL (QU31, QU69 e QU123) para avaliar a produção de proteínas e lipídeos sob diferentes concentrações de glicose (0, 4, 8 e 12%) utilizando casca de mandioca (Manihot esculenta) como fonte de carbono e ureia como fonte de nitrogênio. O uso da casca de mandioca como fonte de carbono para fermentação com YL se mostrou vantajoso, visto que inicialmente o resíduo possuía 1,66% de lipídios e após o processo apresentou ganho de até 1839,5%, enquanto para proteína apresentou incrementos que variaram  de 234,04 até 1674,46%. Na ampla maioria dos casos o aumento do teor de glicose no meio de cultura promoveu diminuição nos teores de lipídeos e proteínas.

In Central Brazil, plateaus, the most common geomorphologic form, have been undergoing intense conversion from native vegetation to pasture and agriculture in recent decades. We used carbon stable isotope ratios (δ13C) and nitrogen stable isotope ratios (δ15N) to assess possible changes in soil organic matter dynamics under such land use modifications. This study aimed to evaluate the differences in soil δ13C and δ15N and C and N stocks between native vegetation and agricultural or pasture areas in different locations of a plateau in the savannas of Central Brazil. We sampled soil up to 100 cm depth in pasture areas in the summit of the plateau and no-tillage and conventional tillage on the border of a plateau, as well as soils under native vegetation in both landscape locations. Both soil δ13C and δ15N, and C and N stocks showed no differences between land uses. The different relationships between δ15N and C/N ratio at different locations indicated distinct behavior of the soil organic matter between the summit and border of the plateau. Therefore, in addition to land-use, landscape location contributes to both δ13C and δ15N, and C and N stocks in the soil of the plateau.
Rethinking Life and Predicting Its Origin
Authors: Gonçalves Diogo
Published: June 2021

The definition, origin and recreation of life remain elusive. As others have suggested, only once we put life into reductionist physical terms will we be able to solve those questions. To that end, this work proposes the phenomenon of life to be the product of two dissipative mechanisms. From them, one reinterprets extant biological life and deduces a testable scenario for its origin. The proposed theory of life allows its replication, reinterprets ecological evolution, creates new constraints on the search for life and lays the foundations for groundbreaking technologies.

There are given algebraic and integral identities for a pair or a triple of plane solenoidal fields. As applications, we obtain sufficient potentiality conditions for a plane vector field. The integral identities are also important for exact a priori estimates.
An Observation on Distribution of Prime Numbers
Authors: Bahrami Dariush
Published: June 2021

In this research first, a sequence of properties called delta is assigned to each prime number and then examined. Deltas are only dependent on the distribution of prime numbers, so the results obtained for the delta distribution can be considered as a proxy for the distribution of prime numbers. The first observation was that these properties are not unique and different prime numbers may have the same value of delta of a given order. It was found that a small number of deltas cover a large portion of prime numbers, so by recognizing repetitive deltas, the next prime numbers can be predicted with a certain probability, but the most important observation of this study is the normal distribution of deltas. This research has not tried to justify the obtained observations and instead of answering the questions, it seeks to ask the right question.
Efficacy Analysis of In Situ Synthesis of Nanogold via Copper/Iodonium/Amine/Gold System Under a Visible Light

. This article presents, for the first time, the kinetics and the general features of a photopolymerization system (under visible light) G1/ Iodonium/ TEA/gold chloride (or A/B/N/G), having initial concentrations of A0, B0, N0 and G0, based on the proposed mechanism of Tar et al. Analytic formulas are developed to explore the new features including: (i) both FRP efficacy and the production of nanogold (NG) are proportional to the relative concentration ratios of (A0+B0+N0)/G0, which may be optimized for maximum efficacy; (ii) the two competing procedure of NG production and efficacy of free radical photopolymerization (FRP) can be tailored for optimal system with nanogold in the polymer matrix;(ii) the FRP efficacy is contributed by 3 components: the coupling of the excited state of copper complex (T) with the radicals (R and S) produced by the iodonium and the amine; (iii) the production of NG is contributed by 2 components: the coupling of T and radical (S) with gold ion; (iv) NG production has a transient state value which is an increasing function of light intensity and the combined concentration ratio [(A0/G0)+(N0/(K'M0). whereas it has a steady-state independent to the light intensity.
Integration of Sharia in Zakat Law
Authors: Aristoni Aristoni
Published: June 2021

Law No. 23 of 2011 on Zakat Management, which is abbreviated as the Law of Zakat Management, places Islamic law as a principle for the management of zakat, which means that every zakat amil in the planning, application, and coordination of collection, allocation of resources must always be based on the regulations of Islamic law. The aim of the writing of this article is to explain the existence of zakat in Islamic law and the law on the management of zakat, Law No. 23 of 2011 as an ius constitutum, and the integration of Islamic law in the law of zakat management. This article can be categorized as a type of research in the library. The method of approach used is a qualitative approach. In addition to a qualitative approach, a normative legal approach is also used in the discussion of this article. The data source used is secondary data, consisting of primary legal materials, secondary legal materials, and tertiary judicial materials. The results of the study show that the existence of zakat in Islamic law and the Law of Zakat Management is an important pillar in building the values of devotion to Allah SWT, justice, and community welfare. The passage of Law No. 23 of 2011 is an inseparable part of the current national legal system (ius constitutum) and the integration of Islamic law in the law of zakat management is reflected in the preamble and in the provisions of Clause 2 of Law No. 23 of 2011 which lay down Islamic law as a principle for the management of Zakat.
Venous Thromboembolic Prophylaxis After Total Hip and Knee Arthroplasty
Authors: Lieberman Jay R. , Bell Jennifer A.
Published: June 2021

➤ The selection of an agent for prophylaxis against venous thromboembolism (VTE) is a balance between efficacy and safety. The goal is to prevent symptomatic VTE while limiting the risk of bleeding.

➤ The optimal agent for VTE prophylaxis has not been identified. The American College of Chest Physicians guidelines recommend that, after total hip or total knee arthroplasty, patients receive at least 10 to 14 days of 1 of the following prophylaxis agents: aspirin, adjusted-dose vitamin K antagonist, apixaban, dabigatran, fondaparinux, low-molecular-weight heparin, low-dose unfractionated heparin, rivaroxaban, or portable home mechanical compression.

➤ The use of aspirin for VTE prophylaxis has increased in popularity over the past decade because it is effective, and it is an oral agent that does not require monitoring. The true efficacy of aspirin needs to be determined in multicenter randomized clinical trials.

➤ Validated risk stratification protocols are essential to identify the safest and most effective regimen for VTE prophylaxis for individual patients. There is no consensus regarding the optimal method for risk stratification; the selection of a prophylaxis agent should be determined by shared decision-making with the patient to balance the risk of thrombosis versus bleeding.

➤ Patients with atrial fibrillation being treated with chronic warfarin therapy or direct oral anticoagulants should stop the agent 3 to 5 days prior to surgery. Patients do not typically require bridging therapy prior to surgery.
E-Learning as a Response to COVID-19 Pandemic: A preliminary study on College Students
Authors: Kartika Siska Ayu
Published: June 2021

There is a dilemma of accepting the new educational system, that we know as “e-learning” by students within educational institutions. We have to replace face-to-face education with distance education in response to the COVID-19. This form of distance education, e-learning, differs from conventional education: being suddenly, unreadily and forcefully implemented.  This study examined and assessed the impact of e-learning to college students, during pandemic. An online survey was conducted amongst some college students in the Mechanical Engineering Dept, at Universitas Balikpapan using a purposive sampling technique. Data were analyzed using Partial Least Square - Structural Equation Modelling (PLS-SEM). The result of this study has confirmed the positive of direct effect variables (attitude, affect and motivation; perceived behavioral intention (ease of use technology, accessibility and cognitive engagement). This study suggests relevant parties to the education system, to improve the implementation of e-learning systems.
