Freundlich, Langmuir, Temkin, DR and Harkins-Jura Isotherm Studies on the Adsorption of CO2 on Various Porous Adsorbents
Authors: Erdogan Fatma Oguz 
Published: December 2018

Abstract
The objective of the study was to prepare low-cost activated carbon from cornelian cherry stones (Cornus mas L.) and compare its adsorption capacities for CO2 with that of commercial multiwalled carbon nanotubes, activated carbon, MCM-41 and four zeolites (silver exchanged, 13X, faujasite type and linde type A). BET, t-plot and DFT methods were used for the characterization of all adsorbent samples based on N2 adsorption-desorption data obtained at 77 K. The produced activated carbon samples (KAC and NAC) were also characterized by scanning electron microscopy (SEM). The adsorption data were evaluated by several isotherm models such as Freundlich, Langmuir, Temkin, DR and Harkins-Jura isotherm models. Langmuir adsorption isotherms constants related to adsorption capacity, Wm were found as 11.496, 6.175, 4.189, 3.986 and 3.50 mmol/g for NAC, KAC, faujasite type zeolit, MCM-41 and AC, respectively. The CO2 adsorption capacities of the silver exchanged, 13X, faujasite type and linde type A zeolites were 10.814, 10.241, 14.608 and 13.343 wt%, respectively. Microporous zeolites showed higher CO2 adsorption capacities than the mesoporous MCM-41 and MWCNT. The CO2 adsorption capacity of commercial activated carbon (AC) was found to be 9.428 wt%, while the CO2 adsorption capacities of activated carbons obtained using NaOH and KOH were found to be 13.685 and 15.057 wt%, respectively. The highest CO2 adsorption capacity of 15.057 wt% was achieved with KAC. It could be confirmed that NaOH or KOH activation plays an important role to determine the porous structure and amount of CO2 adsorbed. Results showed that activated carbon produced from cornelian cherry stones is suitable for the adsorption of CO2 and could be used as a low cost effective adsorbent in the capture of CO2.
Effect of Surface Area and Micropore Volume of Activated Carbons from Coal by KOH, NaOH and ZnCl2 Treatments on Methane Adsorption
Authors: Toprak Atakan , Kopac Turkan 
Published: December 2018

Abstract
This paper investigates the methane adsorption characteristics of activated carbons produced from coal by activation with KOH, NaOH and ZnCl2 treatments at different agent to coal ratios (1:1–6:1) and temperatures (600–800 °C) under N2 flow. CH4 adsorption capacities and desorption behaviors of the activated carbons were examined at 0 °C and 25 °C. The relationship between CH4 adsorption characteristics and surface properties of activated carbons, such as BET surface area determined by N2 adsorption at −196 °C, and micropore volume determined by CO2 adsorption at 0 °C were investigated. Optimal results for CH4 adsorption at 0 °C and 25 °C were obtained for the activated carbon samples obtained with KOH treatment at 800 °C at 4:1 ratio, as 2.67 and 1.12 mmol/g, respectively. The results have shown that CH4 adsorption increased proportionally with micropore volume of activated carbons, whereas BET surface area does not exhibit an exact consistency. CH4 adsorption-desorption isotherms at 25 °C have shown that an increase in mesopore formation caused a decrease in adsorption; but allowed desorption to be reversible. Higher methane adsorption capacities were obtained from activated carbons produced from coal by various treatments in this study than most of the reported results in literature at the similar conditions, indicating the suitability of the evaluated materials for industrial applications of methane storage.

The enclosure method for inverse obstacle scattering over a finite time interval: V. Using time-reversal invariance
Authors: Ikehata Masaru 
Published: December 2018

Abstract
The wave equation is time-reversal invariant.
The enclosure method, using a Neumann data generated by this invariance, is introduced.
The method yields the minimum ball that is centered at a given arbitrary point and encloses an unknown obstacle embedded in a known bounded domain from a single point on the graph of the so-called response operator on the boundary of the domain over a finite time interval.
The occurrence of the lacuna in the solution of the free space wave equation is positively used.

What do they Want? Rebels’ Objectives and Civil War Mediation
Authors: Lutmar Carmela , Terris Lesley 
Published: December 2018

AbstractIn this paper, we focus on mediation in intrastate conflicts, specifically on the impact of rebel group goals on the prospects for mediation. We ask whether the goals for which rebel groups fight (i.e. secession, irredentism, autonomy, greater political rights, government overthrow) have an impact on the likelihood that these conflicts will be mediated. We test our hypotheses on a new data set of rebel groups in Africa 1962–2010.
INM RAS coupled atmosphere–ionosphere general circulation model INMAIM (0–130 km)
Authors: Kulyamin Dmitry V. , Volodin Evgenii M. 
Published: December 2018

Abstract
The paper presents a new INM RAS atmospheric general circulation model, which includes troposphere, stratosphere, mesosphere, and the lower thermosphere, as well as the lower ionospheric regions (INMAIM). Based on the atmospheric part of the INM climatic model INMCM, a new general circulation model was created by adding the middle atmosphere and lower ionosphere description up to 130 km altitudes. A new computational unit for radiative processes calculation was developed for this purpose. For the lower ionosphere a separate plasma chemistry local model was created. The identification of the INMAIM model climate in the mesosphere and lower thermosphere was carried out based on climatological observations. It was shown that model reproduces the general climatic characteristics considerably well.
Traditional Home Slaughtering of Animals in the Framework of EU Legislation. Evidence from Bosnia and Herzegovina
Authors: Kumalić Ismet 
Published: December 2018

Abstract
Traditional home slaughtering of animals is a widespread social practice in the Western Balkans, bringing together families, neighbours, and friends, and contributing to the rise of social capital. Bosnia and Herzegovina is a multicultural country where traditional home slaughtering of animals is mostly practised as seasonal slaughtering by Christian communities and as religious slaughtering by Muslim communities. In the framework of existing EU legislation, meat that comes from home slaughtering can be used for private consumption only. However, these rules are not fully aligned with the practices existing on the ground. This article argues that the Western Balkans’ integration into the EU can affect the sustainability of these practices, and it is therefore necessary to amend the relevant legislation and policies to ensure the implementation of EU regulations while respecting the traditional way of communal meat sharing.
Thermal Resistance of Air-Filled Mattresses: Measurement Repeatability and the Effect of Selected Test Parameters
Authors: Kemp Shelley , Shen Xiaoan , Rossi René , Camenzind Martin 
Published: December 2018

Abstract
There is no standardized test method specifically for determining the thermal resistance (R-value) of air-filled mattresses. Unacceptable inter- and intra-laboratory variations in round-robin testing have been attributed to differences in the test apparatus and test parameters used. To identify relevant sources of variation, the repeatability of the guarded hotplate apparatus (in a double plate configuration) was first characterized, and then the effect of modifying selected test parameters on mattress thickness and thermal resistance was investigated. Two mattress types, in two different sizes, were examined: one contained air only while the other contained air plus a nonwoven polyester fill. It was found that repeatable outcomes could be attained when using the guarded hotplate apparatus (95 % repeatability limit of less than 0.08 m2K/W for all mattresses tested). The modification of test parameters had significant effects on mattress thickness or R-value, or both. External pressure, the temperature difference across the specimen, supplementary insulation, mattress size, and environmental conditions affected both the thickness and R-value of the test mattresses. Inflation pressure, over the range tested, did not have a significant effect on the R-value but did influence mattress thickness. This work highlights the need for the standardization of the test apparatus and test parameters and will aid in the development of a standardized test method.

Authors: Katakam Shesha K. , Frintner Mary Pat , Pelaez-Velez Cristina , Chakraborty Rana 
Published: December 2018

OBJECTIVES:
We compared demographics and work, financial, and satisfaction experiences of early-career and midcareer pediatricians categorized by their childhood and medical school locations.

METHODS:
Data from the Pediatrician Life and Career Experience Study were used to examine the characteristics and experiences of 3 groups, which were categorized as (1) international childhood and medical school graduate (international-IMG), (2) United States childhood and international medical school graduate (US-IMG), and (3) United States or international childhood and United States medical school graduate (USMG). With multivariable logistic regression, we examined the experiences of the groups, controlling for participant characteristics.

RESULTS:
Data from 1467 of 1804 participants were analyzed; 13% were categorized as international-IMGs, 6% were categorized as US-IMGs, and 81% were categorized as USMGs. International-IMGs and US-IMGs were less likely than USMGs to report their race and ethnicity as white and non-Hispanic (26%, 32%, and 71%, respectively; P &lt; .05) and more likely to report caring for patients with public insurance (adjusted odds ratio [aOR] 1.80 [95% confidence interval (CI) 1.27–2.56] and aOR 2.12 [95% CI 1.31–3.42], respectively). International-IMGs were less likely than USMGs to agree that physician colleagues value their work (aOR 0.35; 95% CI 0.21–0.56). Overall, 8 in 10 reported that their work was personally rewarding; international-IMGs were less likely than USMGs to report such satisfaction (P &lt; .05).

CONCLUSIONS:
Among a national sample of pediatricians, international-IMGs and US-IMGs play important roles in workforce diversity. They also report unique challenges. Most are satisfied with their work, but international-IMGs are the least satisfied.
Homofobia internalizada e satisfação sexual em casais homossexuais
Authors: Pompeu Silveira Aline , Cerqueira-Santos Elder 
Published: December 2018

Objetivo: El objetivo desta investigación fue observar la influencia de las variables homofobia internalizada y religiosidad en la satisfacción sexual de sujetos en relaciones con personas del mismo sexo.
Método: Se realizó un estudio con 94 sujetos, 49 hombres y 45 mujeres, viviendo en una relación estable con pareja del mismo, sexo. La hipótesis inicial es que altos niveles de homofobia internalizada y de religiosidad influencian de forma negativa la satisfacción sexual de sujetos en relaciones LGB. Los datos fueron recolectados de forma presencial con cuestionario auto-aplicable abordando: aspectos sociodemográficos, homofobia internalizada, homofobia externa sufrida, satisfacción sexual e índice de religiosidad. Se realizaron comparaciones de media intergrupos con análisis unidireccional ANOVA entre variables estudiadas Se realizó la prueba de correlaciones de Pearson entre las variables y, por fin, un análisis de regresión lineal teniendo como resultado la variable satisfacción sexual.
Resultados: Los resultados apuntaron menores niveles de satisfacción entre los grupos con mayor homofobia internalizada, así como para una diferencia significativa en la satisfacción de sujetos en niveles distintos de religiosidad, confirmando así la hipótesis prevista.
Conclusions: Se discute que la homofobia internalizada prevé negativamente la satisfacción sexual del sujeto, a medida que interfiere en su bienestar subjetivo, y que otras variables, como apertura y religiosidad, también tienen una influencia relevante en este contexto.

Published: December 2018

En el sur del Estado de México el chile manzano (Capsicum pubescens R. y P.) es un cultivo económicamente importante, sin embargo, es afectado por la “marchitez”, enfermedad de raíz que provoca la muerte de la planta. El objetivo fue identificar los organismos asociados y evaluar la variación en respuesta al daño de la marchitez en 16 genotipos (M1-M16) de chile manzano. Se sembraron segmentos de plantas infectadas en medio de cultivo PDA y 3P y se identificaron morfológica y molecularmente a los organismos asociados. Para la interacción patógeno-genotipo, se inocularon los organismos asociados solos y sus combinaciones en C. pubescens. Se identificaron a Fusarium oxysporum, Phytophthora capsici y Rhizoctonia solani como responsables de la marchitez, en los que hubo diferencias en severidad e incidencia entre colonias de F. oxysporum (P?0.01), y de P. capsici (P?0.05). Hubo diferencias significativas (P?0.01) en patogenicidad entre P. capsici, F. oxysporum y R. solani, y combinaciones entre estos. Se observó variación en la resistencia a la marchitez, donde M8 fue el genotipo que presentó resistencia a F. oxysporum y R. solani, y M9 tolerancia a F. oxysporum. Éstos pueden ser aprovechados en el mejoramiento genético para desarrollo de genotipos resistentes.

AS RELAÇÕES CAPITAL/TRABALHO NA ERA DA FINANCEIRIZAÇÃO:MODALIDADES DE INCLUSÃO SOCIAL
Authors: Palomino Hector 
Published: December 2018

Que significados assume a subjetividade dos assalariados no capitalismo contemporâneo no qual prevalecem as finanças? A subjetividade se articula com as relações sociais nas quais os trabalhadores estão inseridos e para a maioria tende a se impor atualmente a dominação do capital financeiro com uma chave política, cultural e ideológica. Com a financeirização, o capital busca confrontar com trabalhadores concebidos como puro custo laboral, esvaziados de subjetividade através de vários caminhos. Pela precarização, mediante a desapropriação de vários direitos laborais; pela crescente automatização, mediante a subordinação tecnológica nas condições de trabalho; através da substituição de contratos trabalhistas por contratos mercantis, deslocando a condição de trabalhador para a figura do empresário. Os assalariados, que seguem constituindo a maioria dos trabalhadores, resistem o esvaziamento de sua subjetividade mediante a ação direta em conflitos trabalhistas, ou mediante a defesa de direitos coletivos sustentados nas instituições trabalhistas que ainda perduram. Atualmente na Argentina, os trabalhadores vinculados em sindicatos expressam uma subjetividade fortalecida pela reconstrução de um centro social que articula a classe operária com as classes medias assalariadas, que impulsiona a mobilização contra as políticas de ajuste implementadas por um regime neoliberalista tardio.
Proton Pump Inhibitors and Bone Health
Authors: Wagner Scott C. 
Published: December 2018

* Proton pump inhibitors (PPIs) are widely prescribed medications that are utilized for the treatment of gastroesophageal reflux and similar gastrointestinal disorders in all patient populations.* There is evidence that prolonged use of PPIs can lead to osteoporosis and altered bone metabolism and can even affect developing bone in pediatric patients.* There is evidence that the use of these medications increases the risk of fractures in pediatric and adult patients, including fragility fractures of the hip and spine in elderly patients.* There is preclinical evidence that the use of PPIs can affect bone-healing after fracture, delaying callus formation and altering the biomechanics of healing bone.* Orthopaedic surgeons, primary-care managers, and gastroenterologists should consider these risks when their patients are receiving prolonged PPI therapy, and the risks and benefits of PPI use should be taken into account when tailoring PPI use to each individual patient.

Fullerene-like Nanoparticles of WS2 as a Promising Protection from Erosive Wear of Gun Bore Nozzles
Authors: Rezgui Narimane , Simić Danica , Boulahbal Choayb , Micković Dejan 
Published: December 2018

Background:
Erosive wear causes increase in the bore diameter of firearms barrels and
nozzles. Most responsible factors for this erosion are friction and heat generated during the shot.
Protection from erosive wear is very important for gun tube life cycle, and various protection methods
are used: adding phlegmatizers in gunpowder composition or applying protective layers on the
gun bore inner surface.

Objective:
In this research, a possibility is examined to protect the surface of a nozzle exposed to
gunpowder erosion applying a layer of tungsten disulfide fullerene-like nanoparticles, IF-WS2,
known as outstanding solid lubricant of a great mechanical resistance.

Methods:
Nanoparticles on the nozzle surface before and after the gunfire tests were observed using
scanning electron microscopy/energy dispersive X-ray spectroscopy. Gunfire tests were performed
on designed erosion device. Temperatures in the defined position near the affected surface were
measured with thermocouples and compared for the nozzles with and without nanoprotection, as well
as the nozzle mass loss after each round.

Results:
For the sample with IF-WS2 lower temperatures after firing and lower mass losses were
observed. Mass loss after first round was 25.6% lower for the sample with protective nanoparticles
layer, and the total mass loss was about 5% lower after five rounds. After the first round the nozzle
without IF-WS2 was heated up to a temperature which was for 150.8°C higher than the nozzle with
IF-WS2.

Conclusion:
Protective function of IF-WS2 is the most pronounced for the first round. The observed
results encourage its further application in firearms gun bores protection.
