The China&ndash;Pakistan Economic Corridor
Authors: Akhtar Aasim Sajjad 
Published: April 2019

Three hundred years after what became known in the nineteenth century as the Great Game—a struggle for regional hegemony between the British and Russian Empires—Southwest Asia remains an imperial staging ground. The U.S. invasion of Afghanistan in September 2001 signaled Washington's desire to cement its hegemonic position, but seventeen years later it is mired in an unwinnable war, even as the U.S. economy—and that of much of the Western world—endures the "endless crisis" of contemporary capitalism.

Allelopathic effect of two medicinal plants on seed germination, seedling growth and grain production of purslane (Portulaca oleraceae L.) weed
Authors: MOUSAVIAN Seyed Nader , ESKANDARI Hamdollah 
Published: April 2019

A laboratory factorial (2 × 5) experiment was carried out based on completely randomized block in four replications to evaluate the effect of plant species and concentration of their allelopathic extracts on seed germination and seedling growth of purslane weed (Portulaca oleraceae L.). The first factor studied was plant species (Artemisia sieberi and Salvia syriaca) and the second one the concentration percentage of plant ethanol extract (0.0, 5 %, 10 %, 15 % and 20 %). The effect of Artemisia on germination reduction of purslane was stronger compared to Salvia. The results indicated that higher extract concentration led to decreased germination percentage, germination speed and seedling growth indices of purslane including leaf length, leaf number, leaf width, leaf dry mass, stem mass and stem length. The effect of Artemisia was higher than that of Salvia. In a complementary experiment, the effect plant residues of Artemisia and Salvia (0.0, 1, 2, 3 and 4 g kg-1 soil) were evaluated in a factorial experiment base on completely randomized block design with three replications. The results of field experiment showed that plant residues significantly (P ≤ 0.01) reduced capsule number per plant, seed number per capsule, seed production and shoot dry mass, while its effect on 1000-seed mass was not substantial. The effect of plant species and the interaction of plant species and their allelopathic extracts concentration had no major impact on the above-mentioned properties. The increase in plant residues in soil, led to the reduction of growth and seed production of purslane induced by plant number per unit area and capsule per plant. Artemisia sieberi Bess. and Salvia syriaca L. residues can be successfully used for non-chemical control of purslane weed.
Glomus intraradices (N.C. Schenck & G.S. Sm.) C. Walker & A. Schuessle enhances nutrients uptake, chlorophyll and essential oil contents and composition in Anethum graveolens L.
Authors: WEISANY Weria 
Published: April 2019

Arbuscular mycorrhizal (AM) fungi are plant-root symbionts whose application in agriculture has been proven its efficiency. However, their application in medicinal plants and their impact on accumulation of essential oils (EO) is still limited. In order to investigate the effect of AM fungi (Glomus intraradices N.C. Schenck & G.S. Sm.) C. Walker & A. Schuessle) on nutrients uptake, biomass production, yield components, chlorophyll content, and EO content and composition in dill (Anethum graveolens L.), a field experiment was conducted as randomized complete block design with three replications. This medicinal plant was grown under AM fungi colonization and non-colonization treatments. Plant inoculation by mycorrhiza increased aerial tissues P and Fe concentrations. However, K, Ca, and Zn concentrations were not affected by AM colonization. The plants inoculated with AM significantly increased plant biomass, chlorophyll content, and EO content by 363 g m−2, 11.83 SPAD and 0.683 % in comparison with non-inoculated plants, respectively. Changes in EO composition were found in AM-colonized dill plants. The contents of myristicin, dill-ether and N-dihydrocarvone increased in EO obtained from AM-colonized plants, while AM colonization resulted in a lesser content of α-pinene, α-phellandrene, limonene, and β-phellandrene.

Authors: KIANI Ghaffar , KATALANI Camellia 
Published: April 2019

Genetic distance between parental lines used in hybrid rice breeding program was estimated based on information from molecular markers data. Sixteen parents (5 CMS, 5 maintainers and 6 restorers) were analyzed with 15 random amplification polymorphic DNA (RAPD) and 20 inter simple sequence repeat (ISSR) marker. Out of 15 RAPD markers, 9 were polymorphic and 79 bands were generated, of which 28 bands were polymorphic (35 %). By using 10 out of 20 ISSR markers 86 bands were detected, of which 35 bands were polymorphic (41 %). Marker index (RAPD = 1.68; ISSR = 1.88) and percent of polymorphic bands indicated that ISSR markers were relatively more efficient in polymorphism detection. Cluster analysis of the parents based on Jaccard’s genetic similarity and UPGMA method were revealed 3 groups. Restorer lines IR68061 and IR5931 with origin of the Philippines were found in distinct group. Results suggesting the cross between CMS lines Neda and Nemat with restorer lines IR68061 and IR5931, can be used as the best heterotic groups for exploration of heterosis.

Authors: LIMA Franklyn da Cruz , SIMÕES Andressa Juliana Almeida , VIEIRA Isabela Maria Monteiro , SILVA Daniel Pereira , RUZENE Denise Santos 
Published: April 2019

Industrial food production causes a high amount of waste. This waste must be taken to a suitable location where it can be further processing. During industrial processing of the pineapple, about 50 % of the mass of the fruit ends up being discarded becoming a residue. Researchers have studied these residues in order to add value to these by-products, to reduce disposal costs and guarantee environmental sustainability. This work investigates the development characteristics of research on agroindustrial residues of pineapple based on bibliometric methods to explore the structure of knowledge in this field over the years, according to the year of publication, periodicals, country, authors, area of knowledge, institutions, keywords, subject type, and citation analysis. In total 927 articles were found and after a careful analysis and selection of papers, 364 articles remained of which 82 % were published only in the last decade. Most studies focused on agricultural and biological sciences. About 1183 authors from 50 different countries contributed to this subject, in which India has the largest number of publications. The results obtained with this study, highlighting the different uses for pineapple residues, can provide valuable information for researchers interested in the field of agroindustrial wastes.

Published: April 2019

Workers in agriculture are regularly exposed to heat stress during summer, which can affect reduced labour productivity and income losses. Air temperatures in Slovenia have been rising in recent decades, and climate change projections show that this trend will continue along with an increase in the number of days with heat stress risk. Changes in the number of heat waves in central and south-western Slovenia for the period 1961–2017 were analysed as well as the risk of the heat stress for workers during heat waves in the year 2017. The heat wave occurs if the temperature threshold for the average daily temperature is reached or exceeded on at least three consecutive days, with the threshold for the mild continental climate (Ljubljana) 24 °C and the mild Submediterranean climate (Bilje) 25 °C. The WBGT (Wet Bulb Globe Temperature) index, assessing the risk of heat stress, was calculated from relative humidity and air temperatures. At both locations, the number of days in heat waves increased as well as their intensity, average daily air temperatures were significantly higher than in the first half of the considered period. The time span, in which the heat waves occur, also extended, as until 1990 they did not appear in early June and late August, as in recent years. The calculated values of the WBGT show that for most days in the heat waves in 2017 in Ljubljana and Bilje, the WBGT 23 °C threshold was exceeded practically all day, which shows a high level of heat stress risk for physically intense work. In the case of exceeded WBGT reference values, employers or farmers themselves should take actions to reduce the risk of heat stress.
Health insurance coverage and health care utilization: Evidence from the Affordable Care Act’s dependent coverage mandate
Authors: Yörük Barış K. 
Published: April 2019

Abstract
This paper investigates the impact of the Affordable Care Act’s (ACA’s) dependent coverage mandate on health insurance coverage rates and health care utilization among young adults. Using data from the Medical Panel Expenditure Survey, I exploit the discontinuity in health insurance coverage rates at age 26, the new dependent coverage age cutoff enforced by the ACA. Under alternative regression discontinuity design models, I find that 2.5 to 5.3 percent of young adults lose their health insurance coverage once they turn 26. This effect is mainly driven by those who lose their private health insurance plan coverage and those who lose their health insurance plan coverage, whose main holder resides outside of the household. I also find that the discrete change in health insurance coverage rates at age 26 is associated with up to a 3.6 percentage point decrease in office-based physician and and up to a 2.1 percentage point decrease in dental visits, but does not have a significant impact on the utilization of outpatient or emergency department services. Furthermore, the effects of the ACA’s dependent coverage mandate on health care spending and out-of-pocket costs are insignificant. These results are robust under alternative model specifications.

Published: April 2019

AbstractThis article is an exploratory journey of cultural visual literacy of “non-conforming” gender representations from pre-colonial Sub-Saharan Africa. It provides select research-based visual evidence of “non-conforming” genders and sexual orientations in traditional cultures of Sub-Saharan Africa as represented in its popular press, scholarly literature, and government and United Nations publications, amongst other sources. These have been selectively described in the context of key cultural themes that include (alphabetically listed): art, folklore, gender behavior, language, marriage, religion, and, sexual activity. The article provides a glimpse of data that were collected during a collaborative project selected by the University of Tennessee’s Howard H. Baker Jr. Center for Public Policy to partner in the U.S. Department of State’s Diplomacy Lab program of engaged scholarship involving two information science graduate students and a faculty member. A few insights from the exploratory journey of the cultural visual literacy of “non-conforming” gender representations are also reported.

Published: April 2019

Abstract
This review summarizes Russian developments on the most important industrial processes of hydrocarbon feedstock refining according to the data of the last 15–20 years on the kinetics of deactivation of heterogeneous and liquid-phase catalysts under non-stationary conditions. The methodological aspects of the creation and application of kinetic models for the deactivation of heterogeneous and liquid-phase catalysts under non-stationary conditions are considered. It is shown that high efficiency of catalytic technologies is ensured by regulation of hydrodynamic and thermal conditions of industrial processes of gasoline reforming, alkane dehydrogenation, alkylation of benzene with higher alkenes and catalytic dewaxing using kinetic models, which take into account catalyst deactivation.
Penčo Slavejkovs „Arbeit in der Gegenwart“
Authors: Danova Sirma 
Published: April 2019

Summary
This article focuses on Pencho Slaveykov’s concept of “work in the present,” which forms the core of his definition of modernity, blending together literature and social experience. Slaveykov’s literary project and author persona are viewed in the broader context of aesthetic modernity. The Bulgarian modernist is a cultural engineer pushing the idea of a differentiation of cultural and artistic spheres. His goal is to autonomize literature after the utilitarian imperatives of the Bulgarian National Revival. The author simultaneously embodies a Balkan ‘crank’ and a German conceptualist. Slaveykov’s work not only demonstrates that modernism has broken with the past, but also constructs an alternative cultural memory shaped in the generic modes of the epic, the lyric, and the anthology. The author entitles himself with the power to be a guardian of cultural memory. Pencho Slaveykov’s conceptualizations envisage the creation of the author as an institution pivotal for the construction of a national literature.
New therapeutic approaches in the treatment of low back pain
Authors: Neculăeș Marius , Lucaci Paul 
Published: April 2019

Abstract
Medical recovery practices have welcomed more and more patients complaining about moderate or intense low back pain.

Aim: This paper aims to demonstrate the efficiency of successive magnetic induction therapy on low back pain syndrome. We assume that the use of successive magnetic induction in the treatment of patients with low back pain will reduce significantly the pain manifestations at this level.

Methods: The study was conducted on 30 patients who displayed important low back pain and decreased lumbar spine mobility. The therapy applied – super inductive system – reduced significantly the pain threshold of these patients and improved the lumbar spine mobility, implicitly.

Results: In order to highlight the results, we interpreted graphically the values of the initial and final testing using the Microsoft Office Excel. There is no doubt that the mobility of the lumbar spine of patients improved considerably, some patients reported that their pain disappeared altogether, while others reported only a mild discomfort.

Conclusion: This study stands to highlight the efficiency of the Super Inductive System, a fact confirmed by the comparison between initial and final results.

Published: April 2019

Abstract

Introduction: Swimming, as an activity, covers many of the basic humanistic needs by creating a state of wellbeing as well as help form a holistic person by developing their motor skills, cognition and affection through the stresses of training for competition or just by practicing for recreational purposes. Various scientific studies show the importance of the motor skill component when selecting those fit for competitive swimming. Additionally, there are other studies that demonstrate that swimming can have an anthropometric effect over the body. The purpose of our study was to test if an initiation level swimming course would produce a development of basic motor skills in children between the ages of 6 to 8.

Methodology and Participants: for this study we recruited 10 participants out of which 5 were girls and the remaining 5 were boys. Their age (7,1±0,73) is between 6 and 8 where two of the children are 6 years of age, five are 7 years of age and the last three are 8 years of age. In order to conduct the study, we employed a set of tests that rely on 7 events extracted from the stock of EUROFIT tests.

Results: the final results show that the participants have improved their performances with strong statistical significance.

Conclusions: Undergoing an initiation level swimming course results in a noticeable development of motor skills as well as from the homogeneity of the group, which is considerably improved at final testing.

Published: April 2019

Abstract
The aim of the research was to emphasize the incidence of spine deficiencies in students with intellectual disabilities involved in the recovery program within the kinetotherapy classes carried out in special schools in Bucharest.
We wanted to point out that among the two categories of children with disabilities enrolled in special education from Bucharest (children with mild / moderate intellectual disabilities and children with serious / severe / profound intellectual disabilities) there are no statistical differences related to the incidence of spine deficiencies.
Research sample consisted of students enrolled in special education from 11 schools. Thus there were formed two groups of students: students with mild / moderate intellectual disabilities and children with serious / severe / profound intellectual disabilities. Another criterion for forming working groups was the school level. Thus, each category was divided into subjects enrolled in primary education and subjects enrolled in secondary education.
The comparison made between the groups revealed that in terms of the incidence of spine deficiencies there is correlation between the type of physical deficiency and the degree of disability.
The effect of physical effort on the psychological dimensions in the case of former athletes
Authors: Chirazi Marin , Șubredu Irina 
Published: April 2019

Abstract
Starting from the theoretical assumptions regarding the fact that the sustained physical effort had repercussions on the mental dimensions and starting from the findings that I came across in practice regarding the fact that the mental state of the athletes varied in time during an endurance test, the aim of the present research was to investigate the effect of stress caused by sustained physical effort specific to endurance tests on the psychological dimensions – in the case of former athletes. The attaining of the set goal was observed through a small scale experimental study case (two subjects of different age). They were involved in an endeavour for establishing a record for sailing the Danube in recreational kayaks provided with space for luggage; random accommodation. During that expedition, a series of mental characteristics of the participants were measured: emotional stability, anxiety level and degree of optimism. The research pointed out the different adaptive capacity of each individual, regardless of age, experience and personality.

Published: April 2019

Abstract
This study aims to identify if there is a relation between postural balance and the accuracy of 7 meters throws in handball. There is an increase need to improve the success of the 7 meters throw, due to its impact regarding a win or loss over the past years during high-end competitions. Subjects: 173 subjects were involved in this study, 123 males and 50 females with the ages between 18 and 21 years old. Materials: We’ve conducted the balance test using the AMTI NETforce BP 400600 force platform and for the accuracy test we’ve conducted a shooting trial that quantified the spread of a series of throws from the 7 meters mark. We’ve observed the radial dislocation, area and length of the center of pressure for the balance test and for the shooting trial we’ve measured the distance of the throw from a preset spot. Results: There were no correlation between the important factors of balance like Dislocation, Area, Length, and throwing percentage for the Circle, Area 1, Area 2, Missed balls. Instead, between the 3 important factors of balance, there are strong and positive correlations, drawing the conclusion that when we have big numbers for center of gravity deviations, total trajectory (cm2) and the area values, the chances to score a goal from 7 meters are lower. Conclusions: The results of the study confirm the hypothesis. The objectives for a future study is to find ways/methods to improve the general balance, in order to increase the efficiency for the 7 meters throwing.
