A new approach to assessing occupational exposure to antineoplastic drugs in hospital environments
Authors: Dugheri Stefano , Bonari Alessandro , Pompilio Ilenia , Boccalon Pierpaolo , Mucci Nicola , Arcangeli Giulio
Published: October 2018

Cytotoxic antineoplastic drugs (ADs) pose occupational risk and therefore require safe handling practices. We created, optimised, and validated an innovative monitoring protocol for simultaneously assessing 21 ADs in the healthcare environment, and also proposed surface exposure levels (SELs) to facilitate the interpretation of monitoring results, as there are currently no occupational exposure limits for ADs. The environmental AD monitoring data were collected in nine Italian hospitals between 2008 and 2017 and include 74,565 measurements in 4,814 wipe samples. Excellent overall recovery and sensitivity of the analytical methods along with innovative desorption automation make this protocol useful for routine monitoring. AD contamination was found in 3,081 measurements, confirming potential exposure in healthcare workers. Samples taken at the beginning and the end of work shifts, allowed to calculate 75th and 90th percentile values for each ADs both in preparation and administration units and we created a traffic-light colour-coding system to facilitate interpretation of the findings. The introduction of SELs will provide a solid basis for improving occupational safety and focusing on contamination control.
Occupational exposure to cytotoxic drugs: the importance of surface cleaning to prevent or minimise exposure
Authors: Viegas Susana , Oliveira de Ana Cebola , Carolino Elisabete , Pádua Mário
Published: October 2018

Healthcare workers who prepare or administer cytotoxic agents run the risk of exposure, and the risks for health are real even at doses lower than those applied in cancer patients, because, in theory, no dose is safe. The most common and problematic route of exposure is through the skin, especially as work surfaces can remain contaminated even after cleaning. This pilot study aimed to demonstrate the importance of having an effective surface decontamination protocol by determining surface contamination with cyclophosphamide, 5-fluorouracil, and paclitaxel as the most common cytotoxic drugs in an oncology day service. Samples were collected before and after drug handling and analysed with high performance liquid chromatography with diode array detection (HPLC-DAD). Of the 29 samples collected before drug handling 23 were contaminated, five of which with more than one drug. Of the 30 samples collected after drug handling 25 were contaminated, eight of which with more than one drug. The two time points did not significantly differ, which evidences a widespread contamination and ineffective cleaning. This calls for revising the cleaning protocol and handling procedure to place contamination under control as much as possible.
Quadratic Performance Analysis of Switched Affine Time–Varying Systems
Authors: Li Wenzhi , Huang Chi , Zhai Guisheng
Published: October 2018

We analyze quadratic performance for switched systems which are composed of a finite set of affine time-varying subsystems, where both subsystem matrices and affine vectors are switched, and no single subsystem has desired quadratic performance. The quadratic performance indexes we deal with include stability, tracking and L2 gain. We show that if a linear convex combination of subsystem matrices is uniformly Hurwitz and another convex combination of affine vectors is zero, then we can design a state-dependent switching law (state feedback) and an output-dependent switching law (output feedback) such that the entire switched affine system is quadratically stable at the origin. In the case where the convex combination of affine vectors is nonzero, we show that the tracking control problem can be posed and solved using a similar switching strategy. Finally, we consider the L2gain analysis problem for the switched affine time-varying systems under state feedback.
State Filtering for Networked Control Systems Subject to Switching Disturbances
Authors: Chabir Karim , Rhouma Taouba , Keller Jean Yves , Sauter Dominique
Published: October 2018

State estimation of stochastic discrete-time linear systems subject to unknown inputs has been widely studied, but few works take into account disturbances switching between unknown inputs and constant biases. We show that such disturbances affect a networked control system subject to deception attacks on the control signals transmitted by the controller to the plant via unreliable networks. This paper proposes to estimate the switching disturbance from an augmented state version of the intermittent unknown input Kalman filter. The sufficient stochastic stability conditions of the obtained filter are established when the arrival binary sequence of data losses follows a Bernoulli random process.
Hardware Reduction for Lut–Based Mealy FSMs
Authors: Barkalov Alexander , Titarenko Larysa , Mielcarek Kamil
Published: October 2018

A method is proposed targeting a decrease in the number of LUTs in circuits of FPGA-based Mealy FSMs. The method improves hardware consumption for Mealy FSMs with the encoding of collections of output variables. The approach is based on constructing a partition for the set of internal states. Each state has two codes. It diminishes the number of arguments in input memory functions. An example of synthesis is given, along with results of investigations. The method targets rather complex FSMs, having more than 15 states.
The autonomy-oriented approach as a way to develop higher medical education
Authors: Gavrilyuk O.A
Published: October 2018

The paper emphasises the potential of the autonomy-oriented approach as a scientific basis for the development of innovative training practices in medical universities of Russia. Based on a review of research, theory, and current teaching practices in Professor V.F. Voino-Yasenetsky Krasnoyarsk State Medical University, the paper considers both theoretical and practical aspects of the autonomy-oriented approach implementation in higher medical education. The benefits of the autonomy-oriented approach for both undergraduate and postgraduate medical students are demonstrated from the perspective of the Self-Determination Theory. Our findings indicate that the autonomy-oriented approach in higher medical education is associated with a more “personalised” teaching style through supporting students’ self-determination, engagement and autonomy. The summative evaluation of the results of the study with participation of 54 medical students and 33 medical university teachers suggests that the use of the autonomy-oriented approach in higher medical education leads to effective implementation of creative, innovative, contextual and problem-based training techniques as well as students’ and teachers’ personal and professional self-development.
Stress–dilatancy relationship for railway ballast
Authors: Dołżyk-Szypcio Katarzyna
Published: October 2018

Knowledge of the mechanical behaviour of ballast is very important for designing a railway track, especially for high-speed lines. The monotonic drained triaxial tests of scaled and fouled ballast presented in literature were analysed using the Frictional State Theory. The stress–plastic dilatancy relationship shows that four characteristic stages of shearing may be specified. The influence of stress level and water content may be quantified by the use of the Frictional State Theory.

Objetivou-se realizar detecção molecular, análise epidemiológica e de fatores de risco associados à infecção pelo vírus da cinomose canina (CDV) em cães em um Hospital Veterinário Escola em Recife, Pernambuco. Foram avaliados 146 cães suspeitos de diferentes sexos, variadas idades e raças. Após a autorização de cada tutor, foi realizada entrevista, sendo utilizada uma ficha própria que continham dados epidemiológicos e clínicos. Foi coletado sangue por venopunção da jugular externa para a realização da pesquisa de inclusão viral e para a detecção molecular do CDV pela técnica de transcrição reversa seguida pela reação em cadeia pela polimerase (RT-PCR). A prevalência da infecção pelo CDV foi de 27,4% (40/146) na RT-PCR, 7,5% (11/146) pela pesquisa de inclusão viral e o teste Kappa não apresentou concordância entre a presença do corpúsculo de Lentz e os resultados da RT-PCR. As cadelas com até seis meses, com definição racial, que se alimentavam exclusivamente com alimento caseiro, com acesso à rua, semi-domiciliadas, criadas dentro de casa e com vacinação incompleta foram mais acometidas pelo CDV. Conclui-se que o vírus da cinomose canina encontrase presente em Recife, PE e que apesar de nenhuma variável epidemiológica ter sido considerada como fator de risco, torna-se necessário que à prática da vacinação regular aos animais sejam reforçadas e pesquisas desta natureza sejam realizadas para controle desta infecção na população canina.

O objetivo deste trabalho foi, por meio de revisão de literatura, tematizar o mel e os parâmetros de qualidade no Brasil. O mel é um produto alimentício elaborado pelas abelhas melíferas, através da transformação de substratos depositados nos alvéolos das colmeias. É composto por diversas substâncias naturais que possibilitam múltiplas aplicações funcionais e terapêuticas. No Brasil a produção comercial foi iniciada na década de 1939, contudo a apicultura passou a ser considerada como agronegócio no ano de 1980. A alta demanda do mel, somado ao razoável valor de revenda, acarretou o surgimento de produtos depreciados e adulterados, sendo as irregularidades identificadas por meio da avaliação isotópica do carbono, análises físico- químicas e microbiológicas específicas. O mel é um alimento saudável e nutritivo. Sua produção gera renda, fixa o homem no campo e contribui ao aumento da diversidade biológica do ecossistema. Os órgãos fiscalizadores, contudo, devem ser atuantes para garantir o comércio de méis adequados ao consumo.

Objetivou-se relatar um caso de linfoma cutâneo não-epiteliotrópico em canino, destacando-se os aspectos clínicos e patológicos da neoplasia. Foi atendido no Hospital Veterinário da Universidade Federal Rural de Pernambuco (UFRPE), um cão de raça Shih-Tzu, macho, não castrado, com sete anos e pesando aproximadamente 5,3kg. O paciente apresentava neoformação ulcerada, eritematosa e com secreção purulenta em formato de anel em região do cotovelo no membro anterior direito e nódulo ulcerado e com presença de crostas em região do membro posterior esquerdo. Foram realizadas análises hematológicas, bioquímica sérica, citologia aspirativa por agulha fina e biópsia para análise histopatológica. No hemograma, detectou-se anemia normocítica normocrômica com leucocitose e neutrofilia relativa e absoluta. Ao exame bioquímico, observouse a presença de hiperproteinemia e hiperglobulinemia. A citologia demonstrou alta celularidade, com presença de células multinucleadas e figura de mitose. No exame histopatológico foi observada acentuada celularidade composta por células redondas, infiltrados neoplásicos dispostos em cordões localizados na derme profunda e tecido subcutâneo, sendo então, estabelecido o diagnóstico de linfoma cutâneo não epiteliotrópico. Por se tratar de uma enfermidade sistêmica, o linfoma torna-se uma neoplasia de difícil tratamento. O diagnóstico pela citologia aspirativa juntamente com o exame histopatológico e sinais clínicos foram essenciais para o diagnóstico de Linfoma não-epiteliotrópico no presente relato.
THE RELATIONSHIP BETWEEN MANAGEMENT OF FLOATING CAPITAL AND PERFORMANCE OF THE COMPANY
Authors: Nazarova V. V. , Glebov S. P.
Published: October 2018

Efficient management of the companyэs floating capital provides an opportunity to create its value by reducing the need for additional financing, increasing profitability, improving liquidity and increasing the efficiency of operations. Floating capital acts as a lever of value creation for owners. An effective model of the management of floating capital allows the company to gain a competitive advantage and increase shareholder wealth. The relevance of our study is due to the need for quality management of the short-term company’s activities to achieve its maximum performance. The purpose of our research was the identification of the nature of the relationship between the components of floating capital and the performance of the Russian companies. The object of the research was the floating capital of the Russian medium and large size companies, analyzed for the period from 2011 to 2016.The subject of the research was a set of floating capital management processes aimed at achieving the company’s strategic goals. To substantiate the relationship between management of the floating capital and the indicator of company’s performance, we used the following metrics: ROA ratio, reflecting the profitability of total assets, as well as indicators of floating capital — the financial cycle of the company and its components: the period of turnover of debtor indebtedness, the period of turnover of accounts payable, and the period of inventory turnover. In order to simulate the relationship between the management of the floating capital and the company’s performance, the authors used the panel regression method to improve the efficiency of the estimates. In order to obtain applied conclusions, the authors built models with fixed and random effects and used cluster standard errors to reduce the impact of data autocorrelation. Based on the study, the authors proved that there is a significant inverse relationship between the length of the financial cycle of the company and the effectiveness of its activities. There was an inverse relationship between the period of accounts payable turnover and the performance of the company. With the rise of the period of turnover of accounts receivable, the performance of the company falls. An inverse relationship was also found between the period of the company’s inventory turnover and the performance of its activities. The results obtained in the course of the research are of great practical value for the management and strategic development of the company. The results of the research can be used in proper management decisions in the field of floating capital. A competent management policy of the company’s floating capital allows for efficient allocation of the company’s resources to improve the quality of its activities, keeping a balance between the predicted risks and performance.
METHODOLOGICAL APPROACHES TO FORECASTING DYNAMICS OF CRYPTOCURRENCIES EXCHANGE RATE USING STOCHASTIC ANALYSIS TOOLS (ON THE EXAMPLE OF BITCOIN)
Authors: Safiullin M. R. , Abdukaeva A. A. , El’shin L. A.
Published: October 2018

The accelerated pace of development of the cryptocurrency market and its integration into the system of economic, operational, financial and other processes determines the need for a comprehensive study of this phenomenon. This is particularly relevant because in recent months, at the state level have intensified discussions on the prospects of the legalization of the cryptocurrency market and the possibility of using its tools in the economic activities of economic agents. Despite the sometimes polar views and approaches at the moment among Russian experts regarding the solution to this issue, the development of the crypto-currencies market is extremely high, regardless of its regulation. This determines and actualizes the scientific research in the field of evaluation of the prospects of development of this market, forming the subject of this study in order to predict the possible effects and risks for the national economic system. The purpose of the article is the development of tools of modelling and forecasting the volatility of the cryptocurrency market on the basis of “foreseeing” fluctuations in the value of “digital money” using special models of autoregression (ARMA, ARIMA). The study was based on the application of a class of parametric models. It allowed describing both stationary and non-stationary time series and on this basis to develop a system of prognostic estimates for the prospects of further development of the series under study. With the help of our ARIMA model, which evaluates the parameters of the analyzed time series of the cryptocurrency exchange rate, we developed a system of prognostic assessments for the short term. The authors proved that the application of such models with a high level of reliability predicts future adjustments in the market under study. It leads to a high level of prospects for their use in modelling future parameters of the cryptocurrency market development. This creates a basis for a business to develop adaptive mechanisms for to emerging price index adjustments of “digital money”.

Introduction

Neurocysticercosis (NCC) is one of the leading causes of epilepsy worldwide. The majority of cases in Europe are diagnosed in immigrants. Currently in Italy, routine serological screening for cysticercosis is recommended for internationally adopted children (IAC) coming from endemic countries. Methods: We retrospectively analyse the results of the serological screening for cysticercosis in IAC 16 years old or younger, attending two Italian third level paediatric clinics in 2001–16. Results: Of 2,973 children included in the study, 2,437 (82.0%) were screened by enzyme-linked immune electro transfer blot (EITB), 1,534 (51.6%) by ELISA, and 998 (33.6%) by both tests. The seroprevalence of cysticercosis ranged between 1.7% and 8.9% according to EITB and ELISA, respectively. Overall, 13 children were diagnosed with NCC accounting for a NCC frequency of 0.4% (95% confidence interval (CI): 0.2–0.6%). Among the 168 seropositive children, only seven (4.2%) were diagnosed with NCC. Of these children, three were asymptomatic and four presented epilepsy. Among seronegative children (n = 2,805), seven presented with neurological symptoms that lead to the diagnosis of NCC in six cases. The sensitivity, specificity, positive and negative predictive value for the diagnosis of NCC were 54.5%, 98.6%, 14.6%, 99.8% for EITB and 22.2%, 91.1%, 1.4%, 99.5% for ELISA. The yield of the screening programme was 437 NCC cases per 100,000. The number needed to screen to detect one NCC case was 228. The cost per NCC case detected was EUR 10,372. Conclusion: On the base of our findings we suggest the ongoing serological screening for cysticercosis to be discontinued, at least in Italy, until further evidence in support will be available.
The Vanishing Object of Technology

Published: October 2018

This video essay offers a poetic meditation on the changing ecology of our everyday technical setups. It focuses on the gradual disappearance of cables, leads, and wires from behind of our computers, music systems, TV sets, kitchen equipment, and other domestic devices that rely on the continuous supply of electricity for their functioning, to explore the aesthetics of such workaday entanglements. Interweaving shots from underneath the artist’s desk taken over a period of one month into a haunting installation of lines, grids and traces, it proposes an intertwined textual and visual engagement with a unique moment in the history of technology.

Military Utopias of Mind and Machine
Authors: Cohen Ibañez Emily
Published: October 2018

The central locus of my study is southern California, at the nexus of the Hollywood entertainment industry, the rapidly growing game design world, and military training medical R&D. My research focuses on the rise of military utopic visions of mind that involve the creation of virtual worlds and hyper-real simulations in military psychiatry. In this paper, I employ ethnography to examine a broader turn to the senses within military psychology and psychiatry that involve changes in the ways some are coming to understand war trauma, PTSD, and what is now being called "psychological resilience." In the article, I critique assumptions that are made when what is being called "a sense of presence" and "immersion" are given privileged attention in military therapeutic contexts, diminishing the subjectivity of soldiers and reducing meaning to biometric readings on the surface of the body. I argue that the military's recent preoccupation with that which can be described as "immersive" and possessing a sense of presence signals a concentrated effort aimed at what might be described as a colonization of the senses – a digital Manifest Destiny that envisions the mind as capital, a condition I am calling military utopias of mind and machine. Military utopias of mind and machine aspire to have all the warfare without the trauma by instrumentalizing the senses within a closed system. In the paper, I argue that such utopias of control and containment are fragile and volatile fantasies that suffer from the potential repudiation of their very aims. I turn to storytelling, listening, and conversations as avenues towards healing, allowing people to ascribe meaning to difficult life experiences, affirm social relationships, and escape containment within a closed language system.
Tactical Tactility: Warfare, Gender, and Cultural Intelligence
Authors: Ali Isra
Published: October 2018

The participation of women in the landscape of warfare is increasingly visible; nowhere is this more evident than in the US military’s global endeavors.  The US military’s reliance on cultural intelligence in its conceptualization of engagement strategies has resulted in the articulation of specific gendered roles in warfare. Women are thought to be particularly well suited to non-violent tactile engagements with civilians in war zones in Iraq and Afghanistan because of gender segregation in public and private spaces.  Women in the military have consequently been able to argue for recognition of their combat service by framing this work in the war zone as work only women can do.  Women reporters have been able to develop profiles as media producers, commentators, and experts on foreign policy, women, and the military by producing intimate stories about the lives of civilians only they can access.  The work soldiers and reporters do is located in the warzone, but in the realms of the domestic and social, in the periods between bursts of violent engagement.  These women are deployed as mediators between civilian populations in Afghanistan and Iraq and occupying forces for different but related purposes.  Soldiers do the auxiliary work of combat in these encounters, reporters produce knowledge that undergirds the military project.  Their work in combat zones emphasizes the interpersonal and relational as forms of tactile engagement.  In these roles, they are also often mediating between the “temporary” infrastructure of the war zone and occupation, and the “permanent” infrastructure of nation state, local government, and community.  The work women do as soldiers and reporters operates effectively with the narrative of militarism as a means for liberating women, reinforcing the perception of the military as an institution that is increasingly progressive in its attitudes towards membership, and in its military strategies.  When US military strategy focuses on cultural practice in Arab and Muslim societies, commanders operationalize women soldiers in the tactics of militarism, the liberation of Muslim women becomes central in news and governmental discourses alike, and the notion of “feminism” is drawn into the project of US militarism in Afghanistan and Iraq in complex ways that elucidate how gender, equality, and difference, can be deployed in service of warfare.
Bioethical Matriarchy: Race, Gender, and the Gift in Genomic Research
Authors: Doucet-Battle James
Published: October 2018

Abstract: The 2013 sequencing of the epigenome and genome from Henrietta Lacks’s HeLa cell line illuminates the bioethical intersections of genomics, race, and gender. Subsequent announcements by Francis Collins and reports in the scientific media referring to Henrietta Lacks as a matriarch, expose the missing political and resource allocations alluded to by the quasi-viral matriarchal designation, an assemblage I term Bioethical Matriarchy. Drawing from field, media, biomedical archival research, I am concerned with the ways African-descent and matriarchal status reproduce the social order, reflecting racialized and gendered histories of kinship, desire, and status inequality. I address these concerns through an anthropological engagement with African American/Diaspora studies and Feminist technoscientific scholarship in both the social sciences and humanities. I build on Richard Hyland (2014), by arguing that unequal and gendered forms of exchange (re)produce wealth and obligations to give, but not necessarily to reciprocate. I discuss why the bioethical, intellectual property, and legal implications of these asymmetrical relationships necessarily take our discussion beyond issues of consent and inclusion to engaging larger questions of reparative and restorative justice.
"Stroke's No Joke": Race and the Cultural Coding of Stroke Risk
Authors: Merid Beza
Published: October 2018

Stroke is a leading cause of death in the US that disproportionately affects African Americans. In a 2009 PSA campaign, the American Stroke Association’s Stroke’s No Joke campaign collaborated with African American stand-up comedians to promote symptom recognition and discourage delays in care seeking among African Americans. Rather than frankly articulating their disproportionate incidence of and death from stroke, however, this campaign hailed African Americans and their stroke risk using an overly broad construction of blackness. This article joins the others in this special feature in examining how blackness becomes an object of knowledge production in medicine by considering how stroke risk becomes racially and culturally coded.
Feminisms, Fuzzy Sciences, and Interspecies Intersectionalities: The Promises and Perils of Contemporary Dog Training
Authors: Weaver Harlan Eugene
Published: October 2018

Tracing histories of interventions in dog training, this paper examines the contemporary divide between "dominance" and "positive reinforcement" training practices. Drawing from writings by scientists and trainers, this article traces the many ways that the doings of much contemporary dog training embody "fuzzy sciences." Examples from ethnographic fieldwork conducted in an animal shelter help demonstrate the ways specific fuzzy sciences of training are feminist, while others are not. The article closes with a consideration of the ways that relationships between humans and animals not only reflect but also shape experiences of race, gender, sexuality, nation, species, and breed, or "interspecies intersectionalities." The article concludes by thinking through the lens of "interspecies intersectionalities" in order to elucidate a promising expansion of the feminist fuzzy sciences of dog training.

The watershed body: Transgressing frontiers in riverine sciences, planning stochastic multispecies worlds
Authors: Woelfle-Erskine Cleo Assan
Published: October 2018

In conversation with Eva Hayward’s writing on transgender embodiment, this paper explores how beaver modify landscapes differently than human engineers, and how human engineering might be transformed through riverine collaborations with beavers. Considering the body variously as a body of water — a river, which draws together all of the above and underground water in a watershed — as like our own trans bodies, and as a slippery double for the psyche of an Anthropocene engineer, July Cole and I argued that thinking with beaver as stochastic transgressors against Manifest Destiny engineering projects could transfigure engineers approaches to their work and river restoration more broadly. What if, rather than trapping beavers into service as “ecosystem engineers,” we assert that humans should engineer as beavers do, in ways that create porous boundaries between land and water and up- and downstream, by way of stick-and-mud, leaky, temporary dams? Here, I theorize a transfigured watershed body through human-beaver-salmon encounters at three salmon recovery sites in the Pacific west: a Karuk-led project on the Klamath river, agency-led beaver relocation projects in the Methow and Yakima watershed, and a citizen science-agency collaborative project in the beaverless Salmon Creek and Russian River watersheds. All three stories concern river and salmon recovery in the Pacific West, where either humans or beavers have initiated collaborative projects to raise water tables, keep rivers from going dry, and improve salmon habitat. These scientists and local knowledge holders’ encounters with beavers and their ponds thick with salmon are inspiring them to change how they undertake habitat restoration projects and also spurring some to reconsider the proper task of human ecologists and engineers, into a mode inspired by beavers themselves.

Geolocation processing to produce spatial greenhouse gases data products consisting of CH4, CO2 and N20 gases has been carried out systematically. The greenhouse gases data are derived from Enviomental Data Record (EDR) Suomi NPP Satellite CrIS and ATMS Sensor products. During this process, there is an obstacle while performing the information data of greenhouse gases concentrations, due to the result of systematic processing files from EDR are still in netcdf format, so that it could not be distributed to users as they expected. The unique of  unlimited netcdf format is that, it displays only numeric values with irregular resolution, unregistered and incompatible with commonly processing data software. This research aims to produce geolocation processing module in order to provide information of greenhouse gases data spatially by using coordinate pixel registration method into image data, convert Digital Number (DN) value with scale corresponding to Indonesian region and interpolation value between pixels with Radial Basis Function (RBF) method using linear function. The result from the geolocation processing module of greenhouse gases data product are concentration information from some altitude level. The product is in geotiff format with 50 km spasial resolusion. AbstrakPengolahan geolokasi untuk menghasilkan produk data gas rumah kaca (GRK) spasial yang terdiri dari gas CH4,CO2 dan N20 telah dilakukan secara sistematis.

The problem of Islamic economics is also increasingly complex with the large number of banks. To meet the needs of transactions, banks have products that are offered to the public. In accordance with the function of the bank, namely collecting and distributing funds to the public. The purpose of channeling funds by Islamic banks is to support the implementation of development, improve justice, togetherness and equal distribution of people's welfare. This paper will answer what is the meaning of al-mashaqqah tajlib al-taysir and how do the Implications of al-mashaqqah tajlib al-taysir in the development of Islamic economy? The result of research shows that the meaning of the rule of al-mashaqqah tajlib al-taysir is the difficulty of bringing convenience. The point is that if implementing a provision of shara' mukallaf faces obstacles in the form of difficulties and limitations that exceed the limits of reasonable capabilities, then the difficulty automatically creates relief provisions. In other words, if we find difficulty in carrying out something that is to be sharia, then the difficulty becomes a justifiable cause to facilitate in carrying out something that is to be provision of sharia, so that we can continue to run the sharia of Allah easily. The implications raised by the rules of al-mashaqqah tajlib al-taysir are the determination of the law of Islamic financial institutions. This impact is seen when Islamic law allows transactions in Islamic banking financial institutions, so that the community will easily meet the needs by transacting with Islamic banking through contracts that have been agreed upon.

The success of a company needs employees who are competent, experienced and strong. Islamic insurance companies certainly require employees who have knowledge about insurance in accordance with Islamic sharia principles. In the case of the Islamic insurance company Bumi Putera Palembang in 2015 to 2016 there are 40 insurance policyholders who worked in a government agency to terminate the employment relationship between the insurance and policyholders. This is because there is no transparency related to monthly installment payments that should be proven by a deposit or proof of receipt of payment in full by the field agent to the policy holder. This is not in line with the principles of Islamic insurance, namely avoiding the elements of gharar, maysir and usury. Islam emphasizes aspects of justice, likes and likes and togetherness faces risks in every effort and investment pioneered. This aspect is the concept offer to replace gharar, maysir and riba that have been happening in conventional institutions. The focus of research is on the competency of agents (wakalah) in the sharia Islamic Bumi Putera insurance company in the city of Palembang. The result is obtained from the conclusions of six indicators and evidenced by the table of productive reports of agents related to product marketing that human resources in agents /wakalah Bumi Putera Syariah Life Insurance have not described competency and professionalism. This can be seen from the lack of insurance products sold, attitudes to field issues and the achievement of the target customers determined by the company.

To study the effect of active functional groups of cross-linking agents on the physical properties of starch polymer films. Standardized methods for studying the indicators of physical properties of polymer films have been applied. The paper presents the results of the study of the effect of crosslinking agents of different chemical structure on the physicomechanical properties, the influence of atmospheric moisture and the resistance to wet treatments of starch polymer films. An improvement in studied parameters of the films with the use of L-tartaric acid was established. It has been proved that the use of L-tartaric acid as a crosslinking agent makes it possible to improve the physical properties of polymer films based on starch. The obtained experimental results are of practical importance for the development of new environmentally friendly polymer materials.

The ability of humans to generate numbers that are really random has always been a subject of debate. This paper investigated the possibility for a group of humans to serve as random number generators. A total of 2344 students, who were not pre-informed to avoid bias, from different faculties within the Federal University of Technology Akure were asked to chose a random number between 1 and 10. Using various statistical tests, we sought answers to the possibility of predictors like participant’s test score, gender, age and school influencing their choice of random numbers. We discovered that the numbers generated are highly random and chaotic despite number 1 being the most selected number across all predictors that was considered. Our study found that gender, test score, age did not significantly influence the choice of number while faculty showed a significant relation α < 0.05.
Flow Characterization of Gas-Solid Mixture in Fluidized Bed Combustion

Published: October 2018

The fluidization behavior of a non reactive gas-solid in the fluidized bed is experimentally and numerically studied. The numerical results are analyzed, and compared with experimental data. Some results on particle image velocimetry (PIV) in 2-D fluidized beds are presented. The PIV applications were used in order to determine the origin of the ejected particles and the particle velocity distribution, using silica sand particles as inert bed material of Fluidized Bed Combustion. The model used commercial CFD software, Fluent, in two-dimensional simulations. Fluent predicted the fluid bed behavior by utilizing its Eulerian Granular Multiphase model where both the gas and solids phases are assumed continuous and fully interpenetrating. The model incorporated the kinetic theory to predict gas-solid interaction. The silica sand (Geldart particle group B) with average size 300μm and 10 cm height are fluidized with ambient air. Some flow rate of air are introduced i.e. 20 CFM, 30 CFM and 40 CFM. When the sand fluidized in FBC, the results show the formation of a big vortex. It happened at the height 0.25–0.33 m from the base. Both the experimental and the numerical results show that increasing the fluidization velocity and fluidization height is correlated with airflow rate
Apakah Demokrasi Cocok untuk Indonesia
Authors: Habibi Muhammad
Published: October 2018

Pertanyaan ini sebenarnya tidak perlu diajukan. Menurut penulis, tidak ada alternatif terhadap demokrasi bagi Indonesia. Apa kita mau kembali ke demokrasi terpimpin? Apa kita lupa malapetaka luar biasa yang mengakhiri demokrasi terpimpin yang juga begitu mengerikan karena populisme demokrasi terpimpin tidak memungkinkan pandangan-pandangan berbeda? Apakah kita menginginkan seorang Pak Harto baru? Tentu model Pak Harto tak mungkin terulang. Kadang-kadang kita lupa bahwa konflik-konflik bernuansa etnis dan agama yang sudah mulai meledak pada tahun-tahun terakhir pemerintahan Soeharto menunjukkan bahwa Soeharto hanya menutup-nutupi, tetapi tidak mengintegrasikan unsur-unsur penuh perpecahan dalam masyarakat.
