Review of LiFi Technology and Its Future Applications
Authors: Alfattani Safwan 
Published: June 2018

Abstract
In order to respond to the increasing demand of capacity and bandwidth caused by the high number of wireless applications and users, LiFi technology was introduced. It uses the visible light spectrum instead of the radio spectrum to transmit data wirelessly through the illumination of LED lamps. The main advantage of this technology is to provide wireless communications with high data rates. Other advantages include efficiency, availability, security and safety. Also, this technology uses free unlicensed spectrum, and it is cost-effective. Additionally, unlike RF systems, no multipath fading and the transmitter and receiver circuits are not complex. However, LiFi has several issues, which include high path loss, sensitivity to blockages and Non-line-of-sight (NLOS) situations. Probably, the biggest issue of LiFi is the uplink communication which is difficult to implement due to practical and cost reasons. Several future applications of this technology include places where RF is restricted such as hospitals and airplanes. Also, it can be used for traffic management, underwater communication, and outdoor access to the Internet. Moreover, it can be combined with WiFi technology either in hybrid technique or aggregated technique. It is found that later technique gives better results. Another possible application is the optical attocells. It is found that the hexagonal cells model is the best for deterministic deployments of optical APs, whereas the hard-core point process (HCPP) model is the best for random deployments. Furthermore, LiFi can be used for multiuser access with high data rate by using non-orthogonal multiple access (NOMA) technique. Due to the great features of LiFi, more applications and everyday life devices will adopt this technology in the future. However, Because of its limitations, it may not totally replace RF technology, but they will work collaboratively to achieve a better performance.
“Punishment Is All the Charity that the Law Affordeth Them”: Penal Transportation, Vagrancy, and the Charitable Impulse in the British Atlantic, c.1600-1750
Authors: Hitchcock David 
Published: June 2018

Abstract
This article examines the policy of penal transportation to the colonies which underpinned the first British Empire in the Atlantic. It argues that the transportation and indenture of the criminal poor came to be justified by empire’s architects as a charitable reprieve from a life course of decaying indigence and idleness. “Charity” of this nature serviced the needs of the British imperial state and its elites, particularly the need for the malleable biopower of indentured labor, but also the demand for increasingly rigorous carceral control. Transportation also created a clear distinction between the poor so reprieved and those still deserving of traditional relief at home. The article names these justifying discourses of judicial punishment-as-charity as “welfare colonialism.” We might view this regime as an early forerunner of the terrible paternalisms of “philanthrocapitalism,” and its operation as fundamental to the first British “Empire of Charity.”

Authors: Sanad H. M. , Ibrahim Alhussein A. 
Published: June 2018

Abstract
The present work has been oriented to prepare radioiodinated olmesartan for a potential cardiac imaging. Olmesartan has been labeled using 125I or 131I with N-bromosuccinimide (NBS) as an oxidizing agent. Many factors like amount of N-bromosuccinimide, amount of substrate, pH, reaction temperature and reaction time, have been systematically studied to optimize high yield of [125I]iodoolmesartan. The biological distribution indicates the suitability of [125I]iodoolmesartan as a novel tracer to image heart.
Evaluation of High Performance Lubricating Greases on the Translatory Oscillation Tribometer (SRV®)
Authors: Patzer Gregor 
Published: June 2018

Abstract
The diversity of lubricating grease species, each with their own complexity and philosophy, raises the demand for the diversification of existing screening methods even in model testing. This article presents an overview of existing standard methods as well as application-oriented testing procedures, which can be used for evaluating friction, wear, and extreme pressure properties of lubricating greases in a model tribometer. For lubricant developers, the SRV® technology platform offers not only testing according to the established test methods and relevant standards, but also the possibility of testing new products in application-oriented load situations. The testing according to standards can be used as a screening test for the grease chemistry and the flow properties of the grease sample. However, it reflects the potential real-life operating conditions of a product in only a very limited way. This article will present test scenarios for such application-oriented friction and wear tests through a few selected examples: Effect of wear particles on the lubricity of a lubricating greaseHigh temperature fretting behavior of industrial greasesSimplified examination of rolling/sliding friction of high performance greases
Reaction–diffusion equation with nonlocal boundary condition subject to PID-controlled bioreactor

Published: June 2018

We study a system of two parabolic nonlinear reaction–diffusion equations subject to a nonlocal boundary condition. This system of nonlinear equations is used for mathematical modeling of biosensors and bioreactors. The integral-type nonlocal boundary condition links the solution on the system boundary to the integral of the solution within the system inner range. This integral plays an important role in the nonlocal boundary condition and in the general formulation of the boundary value problem. The solution at boundary points is calculated using the integral combined with the proportional-integral-derivative controller algorithm. The mathematical model was applied for the modeling and control of drug delivery systems when prodrug is converted into active form in the enzyme-containing bioreactor before the delivering into body. The linear, exponential, and stepwise protocols of drug delivery were investigated, and the corresponding mathematical models for the prodrug delivery were created.

Abdi-Heba, um governante-vassalo em apuros, ou um estrategista audaz?
Authors: Da Silva Omar João 
Published: June 2018

Este artigo propõe um estudo analítico, crítico-literário e histórico-social das cartas de El-Amarna, com ênfase na coleção das correspondências do rei-vassalo de Jerusalém, Abdi-Heba dirigidas ao rei egípcio do século XIV AEC. Portanto, nosso objeto de estudo e análise é a coleção das cartas EA 285 à 291. Veremos que nesse período (século XIV AEC.) as relações entre os governantes das cidades-estados, no território de Canaã eram marcadas por intensos conflitos e hostilidades. O conteúdo das correspondências dos reis vassalos dirigidas ao Faraó (Amenhotep III 1389-1349 AEC., e/ou Amenhotep IV ou Akhenaton 1349-1333 AEC.) é de conflitos, acusações, defesas e denúncias, que dificulta inclusive, uma leitura diretiva e assertiva dos relatos, pois sempre somos conduzidos à mantermos a dúvida, algo muito comum em escritos literários, e especialmente nos escritos antigos.

Published: June 2018

Acetolysed pollen grains of Talinum paniculatum (Jacq.) Gaertn., Talinum triangulare (Jacq.) Willd. pink petals, Talinum triangulare (Jacq.) Willd. white petals and Talinum triangulare (Jacq.) Willd. pink and white petals F1 hybrid were studied in order to document their morphological structures and ascertain features of taxonomic significance among them. All the taxa have generic features which support their classification as a genus as well as distinct features which ascertain their individuality. Generic features include monad pollen unit, acolpate and monocolpate pollen grains as well as circular and ovate pollen shapes. The delimiting features include additional dyads pollen units in T. triangulare white petal and the F1 hybrid of T. triangulare pink and white petals, quadrangular pollen shape in T. paniculatum, bicolpate pollen grain in the F1 hybrid, tricolpate pollens in T. triangulare white petal and T. paniculatum, tetracolpate pollens in T. triangulare pink petal and T. paniculatum and pentacolpate pollen grains in T. paniculatum only. The shape of the pores in T. paniculatum also separated it from the varieties and hybrid of T. triangulare. Based on the pollen size, the pollens of T. paniculatum are Media (25 - 50 µm) while those of the two varieties of T. triangulare and their F1 hybrid are Magna (50 - 100 µm). The taxa of Talinum in this study can be separated based on their palynological features.

Abstract

Background
Systemic treatment for advanced cancer offers uncertain and sometimes limited benefit, while the burden can be high. This study examines the effect of shared decision-making (SDM) training for medical oncologists on observed SDM in standardized patient assessments.

Materials and Methods
A randomized controlled trial comparing training with standard practice was conducted. Medical oncologists and oncologists-in-training (n = 31) participated in a video-recorded, standardized patient assessment at baseline (T0) and after 4 months (T1, after training). The training was based on a four-stage SDM model and consisted of a reader, two group sessions (3.5 hours each), a booster session (1.5 hours), and a consultation card. The primary outcome was observed SDM as assessed with the Observing Patient Involvement scale (OPTION12) coded by observers blinded for arm. Secondary outcomes were observed SDM per stage, communication skills, and oncologists’ satisfaction with communication.

Results
The training had a significant and large effect on observed SDM in the simulated consultations (Cohen's f = 0.62) and improved observed SDM behavior in all four SDM stages (f = 0.39–0.72). The training improved oncologists’ information provision skills (f = 0.77), skills related to anticipating/responding to emotions (f = 0.42), and their satisfaction with the consultation (f = 0.53).

Conclusion
Training medical oncologists in SDM about palliative systemic treatment improves their performance in simulated consultations. The next step is to examine the effect of such training on SDM in clinical practice and on patient outcomes.

Implications for Practice
Systemic treatment for advanced cancer offers uncertain and sometimes limited benefit, while the burden can be high. Hence, applying the premises of shared decision-making (SDM) is recommended. SDM is increasingly advocated based on the ethical imperative to provide patient-centered care and the increasing evidence for beneficial patient outcomes. Few studies examined the effectiveness of SDM training in robust designs. This randomized controlled trial demonstrated that SDM training (10 hours) improves oncologists’ performance in consultations with standardized patients. The next step is to examine the effect of training on oncologists’ performance and patient outcomes in clinical practice.

Background
Steroid-resistant nephrotic syndrome (SRNS) is a frequent cause of CKD. The discovery of monogenic causes of SRNS has revealed specific pathogenetic pathways, but these monogenic causes do not explain all cases of SRNS.

Methods
To identify novel monogenic causes of SRNS, we screened 665 patients by whole-exome sequencing. We then evaluated the in vitro functional significance of two genes and the mutations therein that we discovered through this sequencing and conducted complementary studies in podocyte-like Drosophila nephrocytes.

Results
We identified conserved, homozygous missense mutations of GAPVD1 in two families with early-onset NS and a homozygous missense mutation of ANKFY1 in two siblings with SRNS. GAPVD1 and ANKFY1 interact with the endosomal regulator RAB5. Coimmunoprecipitation assays indicated interaction between GAPVD1 and ANKFY1 proteins, which also colocalized when expressed in HEK293T cells. Silencing either protein diminished the podocyte migration rate. Compared with wild-type GAPVD1 and ANKFY1, the mutated proteins produced upon ectopic expression of GAPVD1 or ANKFY1 bearing the patient-derived mutations exhibited altered binding affinity for active RAB5 and reduced ability to rescue the knockout-induced defect in podocyte migration. Coimmunoprecipitation assays further demonstrated a physical interaction between nephrin and GAPVD1, and immunofluorescence revealed partial colocalization of these proteins in rat glomeruli. The patient-derived GAPVD1 mutations reduced nephrin-GAPVD1 binding affinity. In Drosophila, silencing Gapvd1 impaired endocytosis and caused mistrafficking of the nephrin ortholog.

Conclusions
Mutations in GAPVD1 and probably in ANKFY1 are novel monogenic causes of NS. The discovery of these genes implicates RAB5 regulation in the pathogenesis of human NS.
Coupled-Channel Analyses on 〖Ti〗^(46,48,50)+〖Sn〗^124 Heav-ion Fusion Reactions
Authors: EROL Burcu , YILMAZ Ahmet Hakan 
Published: June 2018

Heavy-ion
fusion near the Coulomb barrier attract experimental and theoretical interest.
The collisons are typically characterized by the presence of many open reaction
channels. In the energies around the Coulomb barrier, the processes are elastic
scattering, inelastic excitations and fusion operations of one or two nuclei.
The fusion process is defined as the effect of one-dimensional barrier
penetration model, taking scattering potential as the sum of Coulomb and
proximity potential. We have performed heay-ion fusion reactions with
coupled-channels (CC) calculations. CC formalism is carried out under barrier
energy in heavy- ion fusion reactions. In this work fusion cross sections have
been calculated and analyzed in detail for the three systems in the
framework of CC approach (using the codes CCFULL[16], CCFUS [17] and CCDEF [18])
. Calculated results are compared with experimental data, including excitation of the projectile and target to the
lowestand states and with the datas computed from ‘nrv’. CCDEF, CCFULL
and ‘nrv’ explains the fusion reactions of heavy-ions very well. There is a
good agreement between the calculated results with the experimental and nrv
results [19].

As espécies de Candida estão entre as principais causas de infecção da corrente sanguínea, promovendo elevados índices de mortalidade, sendo a Candida albicans a espécie mais frequente em infecções hospitalares. Atualmente, diversos medicamentos antifúngicos são utilizados, porém podem ser tóxicos ao hospedeiro e, com o seu uso excessivo, as leveduras têm adquirido resistência ao tratamento convencional. O objetivo do presente estudo é avaliar os efeitos da associação da Terapia Fotodinâmica (PDT) com Azul de Metileno ao óleo Safeteam® e o seu efeito na inativação sobre cepas de Candida albicans isoladas de cateter. O experimento foi realizado com a irradiação dos grupos, em placa de Kline, utilizando LED (Diodo Emissor de Luz) e densidade de energia de 15 J/cm², sendo, posteriormente, incubadas a 37ºC por 48h, e realizada análise quantitativa para avaliar o percentual de redução de Unidades Formadoras de Colônias (UFCs). Quando analisado o efeito da associação do óleo Safeteam® à PDT, foi observada uma significativa redução de UFCs, quando comparado ao grupo controle e o grupo utilizando o óleo e a PDT isoladamente, demonstrando ser uma promissora modalidade terapêutica na inativação, in vitro, de cepas de Candida albicans isoladas de cateter.
<b>The Potters and the Archaeologist: the Clay in the Construction of Different Bodies</b>
Authors: Panachuk Lílian 
Published: June 2018

In this article, guided by experienced ceramists, I was able to delve into the pottery productive universe, not only observing these ceramist women, but thinking with my hands. This commitment to learning a motor skill has allowed new questions to surface, modifying my point of view regarding the artifact. As in the productive process that I have been learning, this text has come and go, and these retakes have been part of its modeling process, of my own learning process. And so, it may seem overly intersubjective, because it approaches frontier paradigms. Focusing on the gestures, the production of the text also gave the groping, with the body being the guide on the way. The gesture is pure ubiquity, being at the same time intellectual and material denotes the know-how itself; or rather, more than that, it allows the doing-being because in building the materiality develops at the same time, the identity. As Leroi-Gourhan (1965, p. 44) said long time before, "it is in what produces or does, not in what is, what a human hand manifest itself as such".

As Ceramistas e a Arqueóloga: a Argila na Construção de Corpos Distintos

A olaria é uma técnica corporal exigente que requer um corpo ativo. É preciso (constantemente) atenção voluntária, treino, repetição, abertura à crítica e autocrítica, tolerância à dor (e de novo). Mas é fundamental saber montar e desmontar - sempre como processo contínuo – o sujeito e a matéria, a pessoa e o objeto, de forma inseparável. O barro é também uma pessoa e a pessoa um corpo-máquina, ciborgue (Haraway, 2000). Um corpo molda o outro de forma relacional (Joyce, 2000) em um processo recíproco de objetivação-subjetivação (Santos-Granero, 2009).
Para as ceramistas com as quais convivo nos espaços urbanos, só existe o ser no fazer, esses verbos se constroem mutuamente e se enredam, não há vida sem argila. Ser essa pessoa tem estreita relação com o fazer cerâmico. Como já aprendemos faz tempo com Simone de Beauvoir e Judith Butler, nos tornamos mulheres nessa construção material e simbólica; e distintas umas das outras, mulheres situadas. Nesse sentido, interessa aqui debater algumas dessas construções e sociabilidades em fazer-ser uma mulher ceramista em um contexto urbano. Elas se constroem em um esforço voluntário, consciente e proativo em seu ofício, como mulheres-ceramistas. Entre ceramistas a máxima “sinto, logo sou” é potencializada, e é então um corpo ativo que aplica uma teoria viva ao seu meio ambiente (Le Breton, 2016).
Nesse artigo pretendo interligar pessoas, coisas e fatos, para construir uma narrativa (parcial) sobre a tecnologia cerâmica e os diferentes corpos que ela produz. A perspectiva, no entanto, não é minha nem delas sendo ao mesmo tempo também nossa. É a argila, narradora da história, que dita o tempo, constrói, conecta e transforma os diferentes corpos. É essa perspectiva da materialidade que desejo seguir, incluindo os gestos técnicos como perspectiva teórico-prática.
