Research about the effect of HCl on the activation of clinoptilolite-Ca natural zeolite on Pb(II) absorption has been done. The purpose of this study is to determine the capacity of zeolite clinoptilolite-Ca activation by HCl can be used as an adsorbent. For analysis of the adsorption we used AAS whereas for zeolite characterization were used XRF and XRD. The analysis parameters are the effect of HCl concentration, particle size, adsorbent mass, contact time, total solution volume, concentration of Pb(II), and PH solution. These parameters were studied to determine the optimum conditions in the adsorption process. The optimum conditions absorption of Pb(II) for the acid activation process shows that the zeolite clinoptilolite-Ca can be used as an absorbent. The adsorption results show that the value of Pb(II) capacity in the activation process with HCl of 0.2 N produces adsorption capacity of 0.0821 mg/g, for particle size 125 Âµm produces and adsorption capacity 0.0821 mg/g, for an adsorbent mass of 0.1 g produces an adsorption capacity of 0.5110 mg/g, for contact time of 10 minutes is 0.5662 mg/g, for a metal solution volume of 12.5 mL is 0.5493 mg/g, for the concentration of metal ion solution 40 mg/L is 2.608 mg/g, and at pH = 7 is 4.923 mg/g. The output of several parameters can be concluded that the adsorption capacity of zeolite clinoptilolite-Ca to the absorption of Pb(II) is 4.923 mg/g. Characterization of zeolite adsorbents with XRF and XRD shows that the zeolite used is zeolite clinoptilolite-Ca. Â Â

ABSTRACT

The development of the tourism industry in Indonesia needs to be supported by appropriate facilities and infrastructure. Hotel as one of the supporting tourism in Indonesia has to be properly expanded. According to the data from Central Bureau of Statistics (BPS), the occupancy rate of star-rated hotels continues to increase over time. One of the factors affecting the customer's decision in choosing a hotel is its interior design. Interior elements consist of floor, wall, ceiling, and furniture. The wall element is one of the interior elements that are attractive to visitors. To find out the perception of hotel visitors, the author surveyed five three-star hotels in Jakarta. The five hotels are Maxone hotel in Matraman, Yellow Hotel in Harmoni, Lynt Hotel in Gambir, Park 5 Hotel and Swissbellinn both are located in Simatupang. The method used in this study is a mixed-method with a visual perception approach in the form of direct interviews and distributed questionnaires to 40 respondents. The results of the research show that several wall criteria of the hotel that are suitable for visitors among others are: bright wall colors and walls with soothing color schemes.

Hypervalent Iodine-Mediated Styrene Hetero- and Homodimerization Initiation Proceeds with Two-Electron Reductive Cleavage
Authors: Hussein Aqeel A. , Ma Yumiao , Al-Yasari Ahmed
Published: August 2020

A mechanistic insight into the hetero- and homodimerizations (HETD and HOMD) of styrenes promoted by hypervalent iodine reagents (HVIRs; DMP and PIDA) and facilitated by HFIP to yield all trans cyclobutanes is reported using density functional theory (DFT) calculations. The initialization involving direct bimolecular one-electron transfer is found to be highly unfavored, especially for the PIDA system. At this point, we suggest that the reaction is initiated with an overall two-electron reductive cleavage of two I─O bond cleavages, affording I(III) (iodinane) and I(I) (iodobenzene) product with DMP and PIDA as oxidant, respectively. The resulting acetate groups are stabilized by the solvent HFIP through strong hydrogen bonding interaction, which promotes the electron transfer process. The nature of the electron transfer is studied in detail and found that the overall two-electron transfer occurs within tri-molecular complex organized by π-stacking interactions and as a stepwise and concerted mechanism for I(III) and I(V) oxidants, respectively. The reaction rate is determined by the initialization step: for I(III), the initiation is thermodynamically endergonic, whereas the endergonicity for I(V) is modest. Upon initialization, the reaction proceeds through a stepwise [2+2] pathway, involving a radical-cationic π-π stacked intermediate, either hetero- or homodimerized. DFT results supported by quasiclassical molecular dynamics simulations show that HOMD is dynamically competing pathway to HETD although the latter is relatively faster, in accordance with experimental observations.

Published: August 2020

Prior to the start of every academic year, the Department of Chemistry and Life Science in the United States Military Academy at West Point conducts a four-week Faculty Development Workshop (FDW). The purpose of FDW is to develop new faculty such that they are prepared to effectively educate students, and a critical hallmark of this program is in-depth feedback and mentorship from senior faculty. With nationwide uncertainty regarding the method of instruction for the upcoming semester, ranging from remote to in-person, and the possibility that schools may need to transition to exclusively remote learning during the semester due to health concerns from Coronavirus disease (COVID-19), this year’s FDW incorporated different modes of instruction. Using classrooms with a maximum capacity of 20 students, new instructors conducted lessons fully remote, in-person with modified classroom paradigms, and through a hybrid approach where half of the students attended class synchronously online and the other half attended class in-person to facilitate social distancing requirements. In the process of preparing new instructors for the upcoming semester and equipping them with tools to teach under varied conditions, numerous lessons were learned on best practices for teaching this fall. In this manuscript, we describe our implementation of FDW and review the aforementioned teaching modalities, with a critical focus on the advantages and disadvantages of each teaching approach during COVID-19 and faculty perceptions on the difficulty and efficacy of each format of instruction.

The study applied a relative risk analysis, which is calculated by comparing observed variables of two groups: total rainfall data (climatic frequencies) and accident sampling (frequency at time of accident).The study bases on the data of road accidents with victims and material damage that have been registered on the А-322 road (Barnaul – Rubtsovsk – the state border with the Republic of Kazakhstan) during the period from 2012 to 2017.

Results. A graph functional dependence and piece wise linear functional dependency were obtained. As the result of approximation, functional dependencies in the form of third-order polynomial function were found.

Practical importance. The obtained functional dependencies can be used in the management system to assess the current risk of road accidents on roads outside build-up areas. The regularity of the inﬂuence of precipitation on the risk of road accidents can be used to implement accident prevention measures at the stage of road design and operation.

Originality. The study contains new results on the nonlinear form of the functional dependence of the amount of precipitation on the risk of road accidents.

Este estudo busca verificar se a simulação clínica colabora para a formação de técnicos em enfermagem em relação às suas capacidades na comunicação com pacientes e seus familiares. Os estudantes foram divididos em dois grupos e avaliados por instrumentos quanto a sua habilidade de comunicação e satisfação com a aprendizagem. Depois, foram entrevistados enquanto realizavam seus primeiros estágios clínicos. Apesar de se demonstrarem satisfeitos, dados da escala e da entrevista demonstraram pouco preparo para comunicarse. Assim, conclui-se que a simulação como atividade isolada tem reflexos apenas indiretos na aprendizagem da comunicação.

Distributed Training of ML Model on Mobile Devices
Authors: Simon Denis Vasilyevich , Shakhova Irina Sergeevna
Published: August 2020

Currently, the need for distributed ML training solutions in the world is increasing. However, existing tools, in particular TensorFlow Federated, are at the very beginning of their development, difficult to implement, and currently suitable exclusively for simulation on servers. For mobile devices, reliable approaches for this purpose do not exist. This article has designed and presented an approach to such distributed training of the ML-model on mobile devices, implemented on existing technologies. It is based on the concept of model personalization. In this approach, this concept is improved as a consequence of mitigating the identified drawbacks. The implementation process is structured so that at all stages of working with the ML-model use only one Swift programming language (Swift for TensorFlow and Core ML 3 are used), making this approach even more convenient and reliable due to the common code base.

In the Covid-19 pandemic phase, some business processes were halted, adapted, and modified to deal with the policy of social restrictions. This impact is experienced by all levels of society, including athletes who are forced to do training from home (Training From Home). Performance evaluation of athletes who do exercises from home must be able to be evaluated remotely, including in terms of presence during the exercise training program. Presence is one of the benchmarks of a person's level of performance or activity in terms of accuracy and discipline in a program of activities. Attendance activities in the form of check-in must be ensured safe and accurate, especially if there is data connectivity with the webserver. This study aims to implement security features with JSON Web Token (JWT) based on the 256 Hash algorithm. The research also implements geo-tagging features to obtain accurate coordinates based on location points. Athlete attendance data obtained by the presence of these features are then synchronized via web service using the REST architecture. All stages of implementation are then tested by the Black Box method, and the results show that JSON Web Token (JWT) is able to secure the authentication and data security process, while the Geo-tagging feature is capable of sending accurate position data. Testing the functionality of the web service shows that all features work well within 44.8 ms, while the positioning accuracy of the geo-tagging feature reaches an accuracy of 90.9%.

Published: August 2020

Today, the development of the use of spatial data is not only used for information geographic or transportation. But also can be used for site selection with integrating decision support system methods. Generated information can help in making decisions and meet the expected aspects. One method that can be used to support the decision making process is the Weighted Aggregated Sum Product Assessment (WASPAS). WASPAS is included in Multi Criteria Decision Making which can produce selected information from the data or criteria used. This study uses the WASPAS method as a determinant of strategic industrial locations by spatial data collection. In determining strategic industrial locations, WASPAS uses several different criteria and weights for each criterion. The WASPAS method can produce precise information related to the determination of strategic industrial locations. The results of the Spearman Rating trial with data on industrial locations in the city of Semarang show a strong conformity, as seen from the resulting compatibility value of 1.0. The results obtained from this study are the establishment of a system model that supports the decision to determine the location of the industry using the WASPAS method.
