Who Needs an Encryption Backdoor: Why Americans want Security over Privacy.
Authors: Endeley Robert E.
Published: August 2020

A qualitative analysis study that examined the views and opinions of non-technology professionals in the U.S. regarding government and law enforcement agencies’ demand for legislation that will allow them to snoop on online private communications of smartphone users. Governments
would prefer exclusive access to encryption technologies, called a backdoor, to use in accessing messages. Technology professionals have, however, argued against a backdoor; they claim a backdoor would not only be an infringement of their privacy but that hackers could also take advantage
of it. In light of this security and privacy conflict between technology professionals and government’s need to access messages in order to thwart potential terror attacks, this study presents the views and opinions of non-technology professionals in the U.S. who are the largest group
of smartphone users, on the ensuing encryption debate. Using qualitative descriptive design methodology, a survey of 26 participants was conducted and data was analyzed using braun and clarke’s six-step process of inductive thematic analysis. Results from this research study showed that
non-technology professionals are willing to allow the government to infringe on their privacy if that will guarantee them security.
Characterization of Zn coated Radio Frequency sputtered AZO thin films
Authors: Ghosh Tushar
Published: August 2020

Transparent conducting oxides (TCOs) have become an essential part of today’s life through their application in touch screen technology. The growing interest for superior and cheap transparent conducting films, primarily driven by the smart televisions and phones market, has led
to renewed efforts to develop novel TCOs. Currently, the most widely used material for transparent conducting applications is Sn-doped indium oxide (ITO), but this material is expensive. Al-Doped zinc oxide (AZO) is among the few metal oxides which can replace costly tin doped indium oxide
(ITO) due to many properties similar to it. Thin films of AZO of different thickness 100 nm, 200 nm, 300 nm were deposited on glass substrates using Al doped ZnO target by RF magnetron sputtering system and 15 nm Zn layer on top of it by DC magnetron sputtering system and annealed in inert
environment. These films show a carrier concentration of 2.28× 1021 cm-3, mobility of 27 cm2/V-s and resistivity of 10-4 Ω-cm. Such a low value of resistivity is attributed to a dense compact columnar morphology of the sputtered films
as evident from FESEM micrograph. The nanocolumns of such close proximity with higher surface related defects increase the carrier concentration enormously. As a result, compact columnar structure improves conduction process and increases electrical conductivity which is comparable to the
standard TCO characteristics used in the optoelectronic devices.
Solution of Euler equations for unsteady flow problems using a central compact scheme
Authors: Kundu Abhishek
Published: August 2020

We solve the Euler equations in one and two dimensions using a central compact scheme coupled with an AUSM+ algorithm. The compact scheme is used in the form of a cell-face interpolation scheme to create the left- and right-states of the primitive variables required by the
AUSM+ based solver. We invoke a TVD limiter to locally apply smaller stencil low-order dissipative formulae near shocks. No extra high-order artificial dissipation is added to stabilize the computation. A number of one and two dimensional test cases has been solved to show the effectiveness
of this approach.

Modelling Of The Response Of Bulk Acoustic Wave Based Devices In Bio Sensor Applications
Authors: Datta T.
Published: August 2020

Bulk acoustic wave device are considered now as a high resolution analytical tools for the real time monitoring of small amount of surface attached mass of bio molecules. Among various mass sensor, acoustic sensors are playing a pivotal role due to their high sensitivity to mass change,
easier in packing and potentially low manufacturing cost. Piezoelectric biosensor is a kind of BAW device that utilize longitudinal wave, known as thickness shear mode that propagates in the bulk of materials. The gravimetrical measurement performed with the piezoelectric biosensor provides
the high precise experimental data. This experimental data is used for quantification of surface mass of the piezoelectric crystal substrate and additional mass applied to the oscillating surface. The theoretical modelling is important for the quantative analysis and interpretation of the
experimental data. For BAW device, a linear relationship is sustained between the shift in resonance frequency and surface mass which cause this shift. But for liquid medium, viscoelastic effect is introduced with the linear relation. Through the formulation of the theoretical modelling it
is possible to show the necessary correction factors of surface mass deduced from BAW device measurement in liquid. Theoretically obtained result must be compared with the experimental value for the liquid phase measurement.

Authors: Fatema Mehroosh , Husain Shahid , Manzoor Samiya , Somvanshi Anand , Zarrin Naima , A.A. Qahtan Aref
Published: August 2020

BiFeO3(BFO)and Bi0.9Nd0.1Fe0.9Ni0.1O3 (BNFNO) nanocrystalline samples have been synthesized through the sol-gel auto combustion process. Frequency and temperature dependent dielectric measurements have been performed
in order to apprehend the influence of (Nd,Ni) co-doping on the conduction mechanism of pristine BFO.Thereal part of the dielectric constant is found to increase with the Nd and Ni doping, which is accredited to higher space charge polarization induced by the dopant ions.The dielectric constant
measured as a function of frequency exhibits a dispersivebehaviour within low frequency region and attains a constant value at higher frequencies. A thermally activated relaxation peak is found at around 500K in the BNFNO samplewhich shifts towards lower temperatures at higher frequencies.
The AC conductivity follows the Jonscher’s universal dynamic law, which has been utilized to evaluate the value of frequency exponent ‘s’. The decrease in the value of the ‘s’ parameter with the increase in temperature establishes that the conduction mechanism
is governed by the correlated barrier hopping (CBH) model. The ac conductivity data has been utilized to evaluate the minimum hopping distance (Rmin) and the binding energies (Wm) of the electrons in BNFNO. Arrhenius equation has been used to fit the experimental data
and activation energy has been evaluated at different temperatures. The Activation energy is found to increase with the increase in the temperatures, owing to the creation of more oxygen vacancies instigated by (Nd, Ni) co-doping.
Spin Hall Conductance In a Two-Dimensional Tight-Binding Model In The Presence Of Rashba Spin-Orbit Interaction And Random Impurities
Authors: Sharma Hemant Kumar , Sil Shreekantha , Chatterjee Ashok
Published: August 2020

The spin-Hall conductance in a two-dimensional tight-binding model is studied in the presence of Rashba spin-orbit interaction and random impurities. The conventional definition of spin current falls through for a system with Rashba spin-orbit interaction because of the non-conservation
of the spin magnetic moment in the presence of Rashba coupling. Using a modified definition of spin-current operator, the relaxation time for electron-impurity scattering is calculated with the help of Matsubara Green function and the spin-Hall conductivity is determined by employing the Kubo-Greenwood
formalism. Our results show the explicit behavior of the spin-Hall conductance as a function of chemical potential, Rashba spin-orbit coupling constant and the impurity strength

Graphene has attracted the scientific research community due to its unique two-dimensional structure, high conductivity, large surface area, superior charge carrier mobility, superior thermal and mechanical properties etc. To obtain graphene by chemical route, graphite oxide (GO) is
used as a medium which is obtained from graphite. There is large amount of hydroxyl, carboxyl, carbonyl, epoxide etc. functional groups attached onto the basal or edge plane of GO making it strongly hydrophilic and easily exfoliated in water. Further reduction of GO get rids of unwanted accessory
functional groups results in formation of reduced graphene oxide (r-GO) having desired properties. Further its properties can be manipulated by synthesis of graphene/r-GO-metal/metal oxide composites according to the applications to be drawn. These composites can be used in various applications,
such as, in energy storage devices like anode materials in lithium ion batteries (LIBs), supercapacitors, photocatalysts, sensors, removal of organic pollutants etc. In the present study, Graphene Oxide-ZnO composites are synthesised by a simple chemical precipitation method. Further the structural
characterizations of the samples prepared are done by X-Ray Diffraction (XRD), UV-Visible Spectrophotometry, Fourier Transform Infrared Spectroscopy and Raman spectroscopy.

Authors: Leelashree S , Babu P.D. , Srinath S. , Kaul S.N.
Published: August 2020

In recent times, LuFeO3 is found to be an interesting material exhibiting room temperature multiferroic properties both in its stable orthorhombic and meta-stable hexagonal phase [1, 2]. To stabilize the single phase and also to enhance the magnetic and ferroelectric properties
rare earth doping is a possibility [3, 4]. In this work, magnetic rare earth atom, Holmium is doped in place of Lu, the structural, magnetic and ferroelectric properties are investigated. Bulk nanocrystallineLu0.9Ho0.1FeO3 compound is synthesized by hydrothermal
method. Doping with ionic radius larger than Lu, helps to stabilize the structure in a stable orthorhombic- Pnma phase. Rietveld refinement of structural data is carried out on the synthesized sample and the lattice parameters are found to be increasing as expected. Also, Ho being an element
with a large magnetic moment, the effect of doping on magnetic properties is investigated. M-H isotherms didn’t saturate even at magnetic field, H= 9T reflecting a strong antiferromagnetic interaction that arises from the super exchange Fe3+-O-Fe3+ interactions.
Finite remnant and coercivity values obtained from the M-H loop measured at 300 K confirms that the TN lies above room temperature (RT). Observation of P-E loop at 300 K confirms ferroelectric ordering at RT.
Producing Renewable Energy in an Alternate Way
Authors: Neogi Saptarshi , Pal Sayantan , Dutta Kakoli
Published: August 2020

In the present work we have discussed and highlighted a special kind of eco-friendly turbine which will produce energy and at the same time will have no negative impact on nature. A turbine is a machine that transforms rotational energy from a fluid that is picked up by the rotor system
into usable energy. But in case of water it requires high water current as well as an artificial dam or a reservoir so that it can work efficiently which have large scale impact on nature. We have shown a new turbine system which requires none of this. Moreover it can be readily installed
in slightly inclined areas beside any canal, drainage system or a river.Similarly like the hydro-turbine the wind turbines are also had to be installed in empty areas such as sea-shores or mountain tops. But if we can install a turbine in the upper atmosphere then it will work more efficiently
due to higher air current. If this turbine is installed with the help of hydrogen or helium system in upper atmosphere it can be operated according to our will.

Published: August 2020

In the present work we have prepared and characterized the two ternary forms of cobalt titanate namely ilmenite and cubic by the sol-gel technique simply by replacing the titanium precursor and using a cationic surfactant micelle solution followed by calcinations at 600°C and 800°C
respectively. In both cases, the nanopowders revealed a dark bluish green color, different morphologies of spherical, rhombus and needle shapes with mean particle sizes 29 and 37 nm, respectively. Bearing growing environmental concerns in mind, we have also highlighted a simple nano chemistry
based clean and efficient process for effective degradation of hazardous malachite green oxalate dye by an in-situ ultraviolet irradiation set-up. In this field there is hardly any report involving comparative study of ternary oxides of cobalt as potential candidates for photo catalytic degradation.
We ultimately observed that cobalt meta titanate proved itself the optimal catalyst at a calcination temperature of 600°C showing a maximum degradation efficiency of 96.38% It also showed a better first-order rate constant of 0.01636 min-1. A decent attempt to correlate photoluminescence
and photo catalysis has also been made. Also, a heterojunction has been fabricated with cobalt meta titanate and the parameters of crucial importance in photocatalysis namely conductivity, carrier mobility, transit time evaluated from the current-voltage characteristics.
Long-range Graphene Surface Plasmon Polariton induced Tunable Optical Bistability in Terahertz Range
Authors: Kar Aparupa , Goswami Nabamita , Saha Ardhendu
Published: August 2020

An idea towards the low threshold optical bistability and tunability of bistable thresholds at THz frequency under realistic situation is analyzed through a proposed multilayered configuration. The proposed configuration comprises a coupling prism of silicon, and monolayer graphene
sheets spatially separated through 35 nm thick polymer which is sandwiched between an air gap of thickness 4.6 μm and a kerr polymer (GaAs) at 300 K temperature and at an incident light frequency of 2 THz. Utilizing the large nonlinear effect of the configuration obtained by the nonlinearity
of the kerr polymer and the high local field effect due to long-range graphene surface plasmon resonance, the switching-down and switching-up threshold values for optical bistability have been markedly reduced upto 1.21×105 V/m and 1.24×105 V/m respectively
thereby rendering a minimum threshold intensity of 7.2 kW/cm2 than the articles reported till date. Tunability of the switching-down and switching-up threshold values have also been realized from 1.21×105 V/m to 5.18×105 V/m and 1.24×105
V/m to 1.424×106 V/m respectively through electrical or chemical modification of the charge carrier density and hence fermi energy of the graphene from 0.23 eV to 0.41 eV and from 1.21×105 V/m to 1.56×105 V/m and 1.24×105
V/m to 2.12×105 V/m respectively for the variation in incident angle from 70° to 88°. The effect of damping rate of graphene on optical bistability behavior has also been observed. Therefore the proposed optical bistable configuration finds potential applications in
the field of all-optical switching, optical transistor, optical logic, nano-illumination and optical memory with low input threshold at THz frequency and can also be used to realize tunable optical bistable device for future THz optical communication technology.
Antiferromagnetism in two-orbital model for s ± -wave iron based superconductors
Authors: Parida P. K. , Pradhan B. , Sahoo S.
Published: August 2020

In iron based superconductors the superconducting phase occurs near the onset of antiferromagnetism order. Unconventional superconductivity has led to extensive experimental and theoretical studies on the effect of electron correlations and on the nature of magnetism in iron based superconductors.
For the study of antiferromagnetism in these superconductors we have proposed a tight-binding two-orbital model Hamiltonian. We have proposed here a s±-wave pairing symmetry of the form coskx × cosky in the model in mean-field approximation.
The model is solved by Zubarev’s double-time Green’s function technique to find the self-consistent gap equation and is solved self-consistently numerically. The antiferromagnetism gap, specific heat, conduction electron density of states and energy band structure for the system
are calculated.

Authors: Florencio Wiliel , Batista Fabiano Ferreira , Reis Cristiane Queiroz
Published: August 2020

Em tempos de crise, empresas com sólida Governança Corporativa (GC) tendem a passar maior credibilidade e por isso enfrentam barreiras mais brandas no mercado de capitais. Desse modo, este estudo teve como objetivo analisar a relação da GC com o desempenho das ações, em períodos com e sem crise. Consideraram-se, para tanto, as empresas do setor comercial listadas na B3, com ações negociadas no período de 2015/2016 (com crise) e 2017/2018 (sem crise), resultando em uma amostra de 20 empresas, totalizando 319 observações. As empresas foram agrupadas por participação ou não em segmento diferenciado de GC (N1, N2 e NM) da B3 e analisadas por meio de estatística descritiva e regressão com dados em painel. Os resultados da estatística descritiva apontam que, em média, as ações das empresas do setor de comércio listadas na B3 “Com-GC” apresentaram melhores desempenhos do que aquelas “Sem-GC”, resultado, provavelmente, da maior transparência das informações prestadas, do tratamento equitativo dos investidores e das medidas de monitoramento dos agentes exigidas pelas práticas de GC. Com relação ao modelo estimado, observou-se significância estatística e sinal positivo para as variáveis independentes lucro por ação (LPA) e a participação dos níveis diferenciados de governança corporativa (1% e 5% respectivamente). Já a variável que capta a crise econômica não se mostrou significante, não se podendo inferir que as práticas de GC são capazes de mitigar os efeitos negativos de crises econômicas no desempenho das ações.

The role of the pharmacist in low back pain management: A narrative review of practice guidelines on paracetamol vs Non-steroidal anti-inflammatory drugs
Authors: Mishriky John , Stupans Ieva , Chan Vincent
Published: August 2020

Low back pain (LBP) is a common and costly condition and a leading cause of disabilities across the globe. In Australia and other countries, there has been changes in LBP management guidelines and evidence in recent years, including the use of pharmacotherapy. Inadequately treated LBP is a burden with significant health and economic impacts. Although there is some variability, non-steroidal anti-inflammatory drugs (NSAIDs) have largely replaced paracetamol as the first-choice analgesic for non-specific LBP in many international clinical guidelines, including the current Australian Therapeutic Guidelines. More recent clinical evidence also supports that targeting LBP with the use of NSAIDs can provide superior and more effective relief of LBP symptoms compared with paracetamol. Community pharmacists are one of the most accessible and frequently visited health professionals that offer vital primary healthcare services aimed to provide enhanced clinical outcomes for patients. The position of a community pharmacist is pivotal in LBP assessment and management, from both a pharmacological and non-pharmacological standpoint, including the use of clinical guidelines, yet their roles are often not fully utilized in LBP therapy. Studies investigating the community pharmacist’s views, practices, knowledge, and roles, specifically in LBP management in Australia are variable and limited. This narrative review will briefly cover the impacts of LBP, and to provide a summary on recent evidence, updates and a comparison of the Australian and international low back pain management guidelines on paracetamol vs NSAIDs in LBP, as well as pharmacists’ roles and interventions in a primary healthcare setting in this context.

A number of studies show that Indonesian religious education currently faces challenges in managing the problem of religious radicalism, especially in the context of a conservative society. This research focuses on various religious problems in the community that teachers often encounter during their interactions in schools and communities, with specific reference to Islamic education. This research was conducted using the Focus Group Discussion method which involved 28 religious education teachers from DKI Jakarta, Banten, and West Java. This research explores recurring religious issues in Indonesian society that require further attention in developing religious education programs. Looking at it from the perspective of religious literacy, this study found that multiculturalism, tolerance, and prejudice are the most recurring problems in society. Recognizing the growing challenges to Indonesia's plural society, religious literacy can be used as an alternative destination for religious education. Religious education must be directed towards students’ correct understanding of various religious beliefs and traditions, in addition to strengthening the faith and practice of students' own religious beliefs.
Pesantren and Social Empowerment: A Critical Analysis On Pesantren Al-Imdad Yogyakarta And Pesantren Maslakul Huda Central Java
Authors: Widayanti Sri
Published: August 2020

Poverty and social problems give rise to many different perspectives and analyzes related to the causative factors and their complexity. These differences have an impact on different social interventions conducted by various parties, including among pesantren in Indonesia. Using qualitative method, this study explores the perspectives and analysis of pesantren on poverty and community empowerment in two pesantrens organizing socio-economic empowerment programs for subordinate groups namely Pesantren Al-Imdad in Yogyakarta and Pesantren Maslakul Huda in Central Java. This research results in three types of analysis, i.e. conventional, semi-progressive and progressive. The conventional analysis defines poverty as community’s inability to meet their basic needs, caused by their own mistakes of not having skills and enterpreneurship so that empowerment is viewed as a tool to direct the community in accordance with the pesantren’s decisions of empowerment programs. The semi-progressive analysis defines poverty as a multidimenstional problem, caused by structural and human factors so that empowerment is viewed as a strategy to increase the capacity of community and pesantren. The progressive analysis defines poverty as multidimentional problem, caused by structural factors and community is seen as a victim of unjust system so that empowerment is viewed as pesantren's alignments to subordinate groups by organizing joint forces to fight for the rights and interests of the community.

The optimal nutrition during pregnancy and lactation is extremely important for the health of both the mother and her infant. It allows realizing the «programming» potential of breastfeeding fully. The World Health Organization (WHO) emphasizes that to achieve better optimization of pregnant and lactating woman nutrition, it is necessary to enhance the introduction of relevant recommendations into practical work. The purpose of the current study is to analyze the results of a survey of women in Russia regarding their awareness of nutrition during lactation. Materials and methods. 1282 women of childbearing age (from 18 to 44 years old) from various regions of the Russian Federation took part in the survey. The questionnaire included 19 questions regarding the socio-demographic characteristics, duration of breastfeeding the nutritional features of women during breastfeeding, as well as the women’s opinions regarding the infant’s responses to changes in mother’s diet. The results of the study indicated that, despite the availability of recommendations coming from professional medical communities, no more than 30% of women received information about nutrition during breastfeeding from doctors. The Internet resources (non-medical websites and blogs) were shown to be the main source of knowledge about this issue (up to 60% of respondents). The results suggest from 30.2% to 42% of women in different age groups regularly to adhere to dietary recommendations. Whereas, they often had false ideas about «forbidden» and «allowed» foods. Thus, 30% of respondents noted nuts, jam, fresh vegetables, juice, fresh fruits as «forbidden» foods. Moreover, mothers with a first-born were significantly more likely to follow a diet compared to women with two (p < 0.001) and three or more children (p < 0.001). Conclusion. An analysis of the survey results showed that women have enough professional information about nutrition during lactation. Therefore, the work on the implementation of professional recommendations on nutrition for pregnant and lactating women should be intensified.

Downy mildew is able to carry out its sexual cycle on resistant grape varieties
Authors: Delbac Lionel , Delière Laurent , Schneider Christophe , Delmotte François
Published: August 2020

Previous studies have shown that new resistant grape cultivars limit epidemics caused by asexual reproduction of downy mildew. However, until now, there was a lack of knowledge on the sexual phase of the pathogen. This study demonstrates that host resistance has little effect on the sexual cycle of downy mildew. Thus, the pathogen can complete its life cycle (asexual and sexual phases) on partially resistant grapevine varieties. The persistence of pathogen populations on partially resistant varieties from one year to the next represents a major challenge for the sustainability of genetic resistance of grapevines.

The study aimed to assess the effects of Papain Enzyme Supplement in Feed on Protein Digestibity, Growth and Survival Rate of  Sangkuriang Catfish (Clarias sp).  Fingerlings used in the study were acquired from the Center for Freshwater Hatchery and Aquaculture, Muntilan, Central Java, Indonesia. The fingerlings had average weight of 3.43±0.50 g/fish. Completely Randomized Design was used in the experiments with 5 (five) treatment and 3 (three) repetitions. The experimental feed contained 31% of protein and 252.06 Kcal/g of energy. Various doses of the addition of papain enzyme were incorporated into the feed, those doses were A (0 g/kg feed), B (2 g/kg feed), C (4 g/kg feed), D (6 g/kg feed) and E (8 g/kg feed).  Parameters of digestibility of protein (ADCP), relative growth rate (RGR), efficiency of feed utilization (EFU), feed conversion ratio (FCR), protein efficiency ratio (PER), survival rate (SR) and water quality were evaluated.  The papain enzyme supplement significantly (P<0.01) influenced on ADCp, RGR, EFU, FCR, and PER, otherwise SR of catfish was insignificantly affected by the papain enzyme supplement. The best treatment result was the addition of 6/kg feed papain enzyme (treatment D). The study concluded that the optimum dose of the papain enzyme supplement for ADCp, EFU, FCR, PER and RGR were 5.65, 5.62, 6.0, 5.66, 6.0  g/kg feed respectively. Water quality during study was still in favorable condition for nurturing Sangkuriang catfish (Clarias sp).

The Red-Blue-Green Light Emitting Diode (RGB-LED) light used in the static lift net can manipulate fish behavior to attract, approach and be concentrated in the lighting area. The purpose of this study is to determine the use of the RGB-LED light intensity with pulse width modulation PWM) value for gathering fish and changing patterns of schooling fish’s movement. Seven treatments with changes in PWM values were the initial conditions, 250, 195, 145, 95 20 and 5 PWM. The methods were by using Hydro-acoustic sonar 360o and ImageJ analysis used to determine the schooling fish’s area in horizontal and vertical by dividing the center zone, main zone, influence zone, and shadow zone. Results of the visualization image of schooling fish as the target fish group visualized by horizontally and vertically. It has the longest duration of 90 ' and 250 PWM has a time duration of 10' shows the difference in the area of schooling fish in four zones. 195, 145 and 95 PWM with each time duration of 10' dominant schooling fish were in the main zone and influence zone, the lowest two light intensities of PWM values were 5 and 20, there are three zones namely center zone, main zone, and shadow zone, schooling fish were increasing with movement pattern by revolving the light source at shadow zone. The approached fish were forming schooling fish because they were attracted to light, with changes in the PWM value that can model the movement patterns of schooling fish.
