Authors: Al-Aboodi Ali H.
Published: March 2019

Safwan-Zubair area is located in the south –west part of Basrah Province in the south of Iraq, this area is involved within the Dibdibba plain which is considered as a part of Iraqi Western Desert. Dibdibba formation consists mainly from sand and gravel with some cementing materials like silt and clay, especially in the west of Zubair area. A linked simulation-optimization model for obtaining the optimum pumping rate of groundwater is presented in this paper. Processing Modflow for Windows (PMWIN v.5) is selected to simulate the aquifer behavior being studied. This model is integrated with an optimization model which is based on the simulated annealing (SA) technique. The calibrated values of hydraulic conductivity vary over the range (15-150) m/day; while, the calibrated values of specific yield vary over the range (0.125-0.45). The objective function converges to a maximum value of (0.636925E+8 m3/year). The percentage ratio of inactive wells is 10.9 %, many wells in the study area that occupy incorrect positions, these wells must be turn off for obtaining optimum pumping rate in the study area.

Published: March 2019

This project is carried out to assess the remediation effect on soil contaminated by molybdenum (Mo), one of heavy metals, through the use of an energy crop, sunflowers. This project explores the integration of phytohormones and chelates in the phytoremediation of soils contaminated by heavy metals, and further assesses the operational measures of remedying heavy-metal contaminated soil with sunflowers, in addition to the related environmental factors. Then the project explores phytohormones and heavy metals on the growth scenario explants (explants morphological analysis) through the experiment. The results indicate that GA3 can increase the growth rate of the plants. The average incremental growth of the heavy-metal-added-only group is 21.0 cm; of the GA3-added group it is 21.9 cm; of the EDDS-added group, it is 20.3 cm; of the GA3+ EDDS-added group, it is 21.7 cm. Compared with the conventional methods of phytoremediation, these integrated measures can actually spur the growth of plants.
Innovative agroforestry interventions for alternative economically viable livelihood development to support climate resilient mountain agriculture
Authors: Kumar Raj
Published: March 2019

Agroforestry holds the key in providing alternative economically viable livelihood development and to support mountainous farmers to adapt to climate change. Innovative agroforestry interventions integrating animal production, horticulture etc into cropping systems exist that can help farmers improve yields and build resilience for supporting livelihoods particularly among marginal communities. But, the lack of knowledge, technical know-how and other information among the farmers are major barriers in adoption of agroforestry. Millions of the farmers of mountainous regions are already wrestling with water scarcity, which would be more severe in climate change scenario. The Himalayan regions are have been considered to be highly sensitive to climate change. Indeed, Innovative agroforestry interventions have the potential to conserve natural resources, improve productivity and provide resilience to climate change. The present paper highlights the need for developing innovative agroforestry interventions to promote various alternate livelihood options through diversification, adoption of high yielding varieties and development of innovative products from forest resources.  Of these spice based agroforetry, silvi-medicinal systems, Van silk cultivation, bamboo and ringal cultivation  and development and use of farm resources based products like  bamboo based composite structures, Seabuckthorn herbal tea, Ghingaroo juice  (Crataegus crenulata) and incense products etc holds a promising potential to be explored as better options for future scenario.
After fire regeneration in a Mediterranean serpentine mountain
Authors: Hidalgo Triana Noelia
Published: March 2019

Abstract: The management of Mediterranean mountains need to know whether or not the flora is adapted to respond to fire and, if so, through what mechanisms. Serpentine outcrops constitute particular ecosystems in the Mediterranean Basin, and plants need to make an additional adaptive effort. The objective of this study is to know the response to fire of the main members of the group of serpentine plants, which habit the Spanish Mediterranean ultramafic mountain, to help in their management. For this purpose, monitoring plots were established on a burned ultramafic outcrop, which was affected by fire in August 2012.They were located in the Mediterranean south of the Iberian Peninsula, Andalusia region. The dominant vegetation of this serpentine ecosystem had been studied previously to fire; it was a shrubland composed of endemic serpentinophytes (small shrubs and perennial herbs) included in Digitali laciniatae-Halimietum atriplicifolii plant association (Cisto-Lavanduletea class) in an opened pine forest. The post-fire response of the plants was studied in the stablished burned plots by field works through permanent 200 x 10 m transect methods, consisting on checking whether they were resprouters, seeders, both of them or if they showed no survival response. Additional information about fire related functional traits is provided for the studied taxa from other studies. Of the total of plants studied (23 taxa), 74% acted as resprouters, 30% as seeders, some of which also had the capacity to resprout (13%), and only 9% of the plants did not show any survival strategy. The presence of a resprouting burl was not high (17%), although serpentine small shrubs such as Bupleurum acutifolium and the generalist Teucrium haenseleri had this kind of organ. The herbaceous taxa Sanguisorba verrucosa, Galium boissieranum and Linum carratracense were seen to be resprouters and seeders. The serpentine obligated Ni-accumulator, Alyssum serpyllifolium subsp. malacitanum, did not show any survival strategy in the face of fire and therefore their populations need monitoring after fires. In the studied ecosystems no species had traits that would protect the aerial part of the plant against fire, although most of the species are capable of post-fire generation by below ground buds. Our results show that the ecosystem studied, composed of taxa with a high degree of endemism and some of them threatened, is predominantly adapted to survival after a fire, although their response capacity may be decreased by environmental factors.
Soil properties across a chronosequence of Ailanthus altissima in semiarid plantations
Authors: Aghajani Hamed
Published: March 2019

Afforestation is a main tool for preventing desertification and soil erosion in arid and semiarid regions of Iran. Large-scale afforestation, however, has poorly understood consequences for the future ecosystems in the term of ecosystems protection. The objective of the present study is to identify changes in soil properties following different intervals of planting of Ailanthus altissima (tree of heaven) in semiarid afforestation of Iran (Chitgar Forest Park, Tehran). For this purpose, sand, silt and clay ratios, bulk density, soil moisture, pH, electrical conductivity, phosphorus, potassium, magnesium, calcium, sodium, total soil N, and total carbon was measured. Our study highlighted the potential of the invasive trees by A. altissima, to alter soil properties along chronosequence. Almost all soil quality attributes showed a declining trend with stand age. A continuous decline in soil quality indicated that the present land management may not be sustainable. Therefore, an improved management practice is imperative to sustain soil quality and maintain long-term productivity of plantation forests. Thinning activity will be required to reduce the number of trees competing for the same nutrients especially in a older stand to protect forest soils.

Antimicrobials in food packaging are used to enhance quality and safety by reducing surface contamination of processed food. This study investigated the effects of Aloe vera- coated packaging materials on the microbial quality characteristics of breadfruit flour. Breadfruit flour was packaged in Jute bag (JB), Kalico bag (KA), low-density Polyethylene-lined Brown paper (LDPEBP) and they were compared with control. Samples were analyzed for changes in microbiological (total colony count and total fungal count) and moisture content during a storage period of 12 weeks interval during storage at ambient temperature of 25 ± 2oC. Packaging significantly (p< 0.05) affected the moisture content and microbiological of breadfruit flour during storage. The moisture content, total colony count, and total fungi count significantly (p< 0.05) increased as the storage time increased. The sample packaged in Brown paper (BP) were more acceptable than those in other packaging materials.
“A new approach for the Classification of Advanced Vehicles in Transportation Systems”
Authors: Orlando Giannattasio
Published: March 2019

Automated vehicles represent one of the most active research topic in different engineering fields in the recent years; in particular, transportation systems theory, mathematical modeling, informatics and electronics are all involved in the development of more efficient, accurate and error resilient systems regarding this topic. For modeling purpose, it is useful to introduce a vehicle classification, but the current 6 SAE levels are too detailed, without sharp borders in some case, to be useful for practical applications; thus a 2-class meta-classification has been proposed but it seems too coarse. This paper starts from an analysis of the 6 SAE levels and of sensors developed and used in modern vehicles to establish a relationship between them; this study is useful to devise a new effective 3-class meta-classification useful to transport systems analysis involving automated vehicles.
The effects of interest rates on the valuation of highway infrastructure assets
Authors: Vergara-Alert Carles
Published: March 2019

The discounted value of cash flows of assets is negatively related to interest rates (i.e., the discount rate effect). However, economic activity is positively related to interest rates and positively related to the cash flows of assets with tariffs that can be adjusted to manage demand such as adjustable-rate toll roads, but uncorrelated to assets that do not bear demand risk such as non-toll roads (i.e., the cash flow effect). This effect arises in some types of assets from: (i) the positive correlation between economic activity and demand for the infrastructure assets; and (ii) the positive correlation between economic activity and inflation. We find that the cash flow effect dominates the discount rate effect for assets with tariffs that can be adjusted to manage demand and, therefore, the value of these assets increases in periods of economic expansion. Nevertheless, the opposite occurs for assets that do not bear demand risk.

Published: March 2019

SAFEPOST is an FP7 European project which was active from April 2012 to July 2016 with the goal of a “reuse and development of Security Knowledge assets for International Postal supply chains”, as its full title explains. SAFEPOST addressed threats to postal security by designing and experimenting a sensor network detection system including gas, radiation, Raman spectroscopy and image-based sensors. In 2015, while SAFEPOST was running, the US Postal Service and IBM suggested the idea of applying sensors to the postal infrastructure components to bring the acquired data to the next supply chain level and optimize efficiency and costs, leading to an Internet of Postal Things.In this paper we provide a perspective view on how the SAFEPOST and Internet of Postal Things approaches can be merged and generalized to supply chains involving not only postal items, but also logistic infrastructures and business processes, in order to design an Internet of Safe Postal+Things.
Optimization of EDM Process Parameter for MRR and SR of 17- 4 PH Steel Using Response Surface Methodology
Authors: NAGPAL SHUBHRATA
Published: March 2019

In the present work, an attempt has been made for material removal rate and surface roughness by response surface optimization techniques in Electrical discharge machining. Electrical discharge machining, commonly known as EDM, is a process that is used to remove metal through the action of an electrical discharge of short duration and high current density between the work piece and too. This work presents the results of a mathematical investigation carried out to the effects of machining parameters such as current, pulse on time, pulse off time and lift time on material removal rate and surface roughness in electrical discharge machining of 17-4 PH steel by using copper electrode. Response surface methodology and ANOVA techniques are used for data analysis to solve the multi-response optimization. To validate the optimum levels of the parameter, confirmation run was performed by setting the parameters at optimum levels. Material Removal Rate during the process has been taken as productivity estimate with the objective to maximize it. With an intention of minimizing surface roughness is been considered as most important output parameter. It is found that the good agreement of that current is most significant parameter for material removal rate and less for surface roughness followed by pulse on time and lift time.

Authors: Chien Tsair-Wei , Tu Mei-Yu , Chou Willy
Published: March 2019

Background: Whether the international author collaboration and keywords on the topic of transportation management has been changed in the last several decades remains unclear. Along with the big data and API(allocation programming interface) emerged as a field of research with increasing attention being paid to it by scientific researchers and a rapid increase in related literature being reported using the bibliometric analysis, the international author collaboration and keywords should be explored to analyze the current state of research, including publication outputs, in-depth collaboration characteristics and keyword topics of transportation management research.Methods: The authors collected two published papers in Medline library and downloaded their 206 similar articles without duplication since 1977. Various statistical techniques and bibliometric measures were employed, including publication growth analysis; journal distribution; and collaboration network analysis at the author country/area collaboration level. The visualization maps of international author collaboration and burst terms were drawn on Google maps using social network analysis(SNA) and cluster analysis. Gini coefficient(GC) was applied to measure inequality of density indices among clusters.Results: A total of 208 bibliographic records on transportation management were collected. The earliest paper was published in 1977, with the number of papers sharply rising at the inflection point of the year 2014. We found that (1) the most number of papers on the topic of transportation management are from the U.S.( 43,27.04%), Spain(21,13.21%), and China(18, 11.32%); (2) the most linked keywords are organization & administration, analysis, education, and statistics & numerical data, and trends; (3) keyword networks presents lower GC that author collaborations among their respective clusters.   Conclusions: The collaboration of international authors on transportation management is not tight and stable. The focus of research topics on transportation management is centralized(Gini=0.48) more than that of author collaboration(Gini=0.33). Our study might provide a potential guide for future research on the topic of transportation management.

Authors: Hosseini1 Seyyed Amirhosein , Rahmani2 O.
Published: March 2019

The size effect on the free vibration and bending of a curved FG micro/nanobeam is studied in this paper. Using the Hamilton principle the differential equations and boundary conditions is derived for a nonlocal Euler-Bernoulli curved micro/nanobeam.  The material properties vary through radius direction. Using the Navier approach an analytical solution for simply supported boundary conditions is obtained where the power index law of FGM, the curved micro/nanobeam opening angle, the effect of aspect ratio and nonlocal parameter on natural frequencies and the radial and tangential displacements were analyzed. It is concluded that increasing the curved micro/nanobeam opening angle results in decreasing and increasing the frequencies and displacements, respectively. To validate the natural frequencies of curved nanobeam, when the radius of it approaches to infinity, is compared with a straight FG nanobeam and showed a good agreement.

Published: March 2019

With increasing environmental concerns, much effort has been spent in research regarding development of sustainable processes for production of fuels and chemical products. In this context, hydrothermal liquefaction (HTL) has gained increasing attention, as a possible route for the chemical transformation of organic raw-materials, some sort of biomass, for example, into liquid oils at temperatures usually below 400°C, under moderate to high pressures (5 - 25 MPa), usually in the presence of a suitable catalyst. In the present work the thermogravimetric (TG) behavior under inert atmosphere of pure green coconut fiber and mixtures thereof with a spinel phase (Fe2CoO4), acting as catalyst has been studied. Spinel samples have been produced at 1000°C and different calcination times (3h, 6h and 9h). Both raw and synthesized materials were characterized  through different techniques, such as scanning electron microscopy (SEM), X-ray diffraction (XRD) and Infrared Absorption Spectroscopy (FTIR). According to the TG data, the catalyst produced during a calcination time of 9h showed a superior behavior regarding the lignin full thermal decomposition, which developed without fixed carbon formation. The results further suggest that the mixing process has a significant effect over the measured degradation kinetics, as it has a direct influence over the contact between catalyst and fibers. The kinetic modelling applied to the dynamic TG signal allowed a quantitative representation of the experimental data. The global process activation energy and order have proven to be respectively, 85.291 kJ / mol and 0.1227.

Published: March 2019

A crescente geração dos Resíduos de Serviço de Saúde (RSS) ao longo dos anos tornou-se grande desafio para as gestões tanto pública quanto particular, em termos de sustentabilidade. Além da complexidade inerente ao tema, a falta de informação/capacitação ainda é bastante frequente. Devido aos riscos em potencial, o gerenciamento dos RSS faz-se obrigatório e necessário em estabelecimentos geradores. Nesse cenário, o Plano de Gerenciamento de Resíduos de Serviços de Saúde (PGRSS) surge como ferramenta essencial para uma gestão sustentável, visando o correto manejo, destinação e disposição adequada de tais resíduos. O presente estudo tem por objetivo apresentar uma análise quantitativa dos resíduos em um hospital de grande porte no município de Juiz de Fora – MG, correspondente aos anos de 2015 e 2016, considerando estudos gravimétricos e financeiros envolvidos em tal geração. Como resultado, verificou-se uma geração mensal de cerca de 52 toneladas de resíduos no estabelecimento, pertencentes às classes A, B, D e E, totalizando 3,30 kg/leito/dia. Verificou-se que a comercialização de resíduos recicláveis gera uma renda de R$43.500,00 com potencial de incremento com a melhoria de ações de segregação na fonte e consolidação do PGRSS. Por fim, destaca-se que a implantação e operacionalização do PGRSS, com a sensibilização e participação dos atores envolvidos, contribui para melhorias no manejo, destinação e disposição final adequada dos RSS, culminando em ganhos sociais, ambientais e econômicos.

Published: March 2019

Study aim: Oxygen Uptake (VO2) is avaluable metric for the prescription of exercise intensity and the monitoring of training progress. However, VO2 is difficult to assess in anon-laboratory setting. Recently, an artificial neural network (ANN) was used to predict VO2 responses during aset walking protocol on the treadmill [9]. The purpose of the present study was to test the ability of an ANN to predict VO2 responses during cycling at self-selected intensities using Heart Rate (HR), time derivative of HR, power output, cadence, and body mass data.

Material and methods: 12 moderately-active adult males (age: 21.1 ± 2.5 years) performed a50-minute bout of cycling at a variety of exercise intensities. VO2, HR, power output, and cadence were recorded throughout the test. An ANN was trained, validated and tested using the following inputs: HR, time derivative of HR, power output, cadence, and body mass. A twelve-fold hold-out cross validation was conducted to determine the accuracy of the model.

Results: The ANN accurately predicted the experimental VO2 values throughout the test (R2 = 0.91 ± 0.04, SEE = 3.34 ± 1.07 mL/kg/min).

Discussion: This preliminary study demonstrates the potential for using an ANN to predict VO2 responses during cycling at varied intensities using easily accessible inputs. The predictive accuracy is promising, especially considering the large range of intensities and long duration of exercise. Expansion of these methods could allow ageneral algorithm to be developed for a more diverse population, improving the feasibility of oxygen uptake assessment.
The Effect of Perceived Transformational Leadership Style on Employee Engagement: The Mediating Effect of Leader’s Emotional Intelligence
Authors: Milhem Marwan , Muda Habsah , Ahmed Khalil
Published: March 2019

Employee engagement has been at the center of attention for human resource personnel and researchers who stated that employee engagement can be a key driver of an organization's business success. Many researchers have found in recent researches that a transformational leadership style has a beneficial connection with employee engagement. Thus, this study aims to find the causal effect of perceived transformational leadership on employee engagement through the mediating role of leader’s emotional intelligence. We analyze the data from a sample of 338 full-time employees working in the ICT sector in Palestine using confirmatory factor analysis (CFA) and structural equation modelling (SEM) to test the hypothesis. Later, the bootstrapping analysis was conducted to confirm the mediation test in this study. The finding shows that transformational leadership style has a significant effect on employee engagement for the mediating role of emotional intelligence. The effect of transformational leadership on employee engagement was found to be completely mediated by leader’s emotional intelligence at work. Theoretically, this empirical study contributed to the new knowledge on the unique mediating effects of leader’s emotional intelligence in the relationship between transformational leadership and employee engagement in the Middle Eastern Region. Practically, this study has managerial implication in the area of organizational management, leadership and human resource management.
Antonio Rosmini’s Social Ethics and his Relationship to German Thought
Authors: Krienke Markus
Published: March 2019

Putting the economic and social–ethical thought of Rosmini in relationship to the German tradition of social market economy, either a pertinent collocation of the liberal catholic thinker Rosmini or new perspectives for the concept of social market economy, which is in search for a new identity, have been made. The justification of this paper lies in the fact that Rosmini introduced the idea of social justice right in the sense of social market economy, on the one hand, and in the way in which the late 19th-centrury economic theory in Italy received his economic thought, on the other hand. Hence, despite his theoretical and cultural distance from Röpke, both have many interesting economic reflections in common.
Catholic Social Teaching as a Pillar of Social Market Economy
Authors: Nothelle-Wildfeuer Ursula
Published: March 2019

This paper presents different historical and systematical approaches to point out the relationship between Catholic social teaching and social market economy. A fundamental connection between Catholic social teaching, ordoliberalism, and the market order is given in more detail. It becomes clear that not every form of capitalism is suitable for Catholic social teaching. However, the so-called “Rhenish capitalism”, i.e., social market economy, is the form of market economy that best coincides with the criteria of Catholic social teaching. This paper examines the anthropological and ethical foudations of the economic order in a detailed manner, especially of the economic order, especially the fundamental value of freedom as well as the notion of social justice by taking into account the importance of an ethos and an institutional framework. The idea of social market economy has to face current challenges and future perspectives which prove that – from an ethical point of view – the center of this discussion is the question of ineluctable standards of humanity and justice.
Federalism in Germany, Italy, and the European Union: History, Characteristics, and Perspectives
Authors: Jochimsen Beate
Published: March 2019

Federalism is always torn between the principles of subsidiarity and solidarity. Defining the federal structure of a country by finding the welfare-maximizing amount and design of government layers is challenging. Thereby, the financial endowment of different layers of government which they need to fulfill their respective tasks is an important aspect. European countries have chosen quite different federal designs to address the question of an optimal degree of fiscal decentralization. The aim of this paper is to analyze these different approaches for Germany, Italy, and the European Union. Parallels can be found in that all the three entities share a form of institutional asymmetry, a kind of fiscal bailout system, and a sort of fiscal equalization scheme.

Published: March 2019

In the context of all countries are moving towards a dynamic and developed economy, it would be impossible not to mention the "labor factor". Obviously, this is an influential factor because the higher quality of labor resources will result in a more conveinent and easier economic development process and vice versa. However, the social mobilization of labor resources, especially high-quality S&T human resources, has become a tough reality. This phenomenon has become more and more popular and complicated within organizations and countries. There are many manifestations of the social mobility phenomenon of high quality S&T human resources, but in this article, the authors focus on two social mobility flows which are social mobility with migration, also known as "brain drain" and social mobility without migration – "internal brain drain". The authors conducted a survey on the current status of social mobility of high-quality S&T human resources in two national universities of Vietnam: Vietnam National University, Hanoi and Vietnam National University, Ho Chi Minh City in order to recognize the highlights and trends of this phenomenon. From that, the authors set out a number of policy suggestions to minimize the negative impacts from social mobility and to improve the efficiency of using high-quality S&T human resources in Vietnam universities today.
Application of the Advanced 2D Multi-electrode Electrical Exploration Method to Survey the Current Condition and Contribute to Assessing Stability of Dykes
Authors: Chung Do Anh , Minh Vu Duc
Published: March 2019

One of the important issues to assess the stability of dykes is to survey and assess their current condition. This article introduces some new results obtained from applying Advanced 2D Multi-electrode Electrical Exploration method to survey the current condition of Red River dyke in Hanoi, Cau River and Thai Binh River in Bac Ninh province. Comparing survey results between Advanced 2D Multi-electrode Electrical Exploration method and drilling method show that layering results match each other. However, drilling and sampling method is very difficult to identify objects that cause instability in body and foundation of dyke (seepage caused by sand lens, mud pit inside dyke’s foundation…), while these objects can be identified by the Advanced 2D Multi-electrode Electrical Exploration method. Therefore, instead of traditional surveying method,  it is possible to apply the Advanced 2D Multi-electrode Electrical Exploration method to survey the current condition and contribute to assessing the stability of dyke sections to add into and complete the database on dykes for highly efficient management and maintenance of dykes.

Authors: Tanwir Ahmad Malik Bilal Nawaz, Saira Sattar,
Published: March 2019

The experiment was laid to analyze genetic features, genotypic and phenotypic correlation coefficients, path analysis with regression analysis among yield contributing traits in a selected F3 populations of upland cotton including parents. In this research experiment ANOVA showed significant difference among all individual plants in F3 populations. Monopodia per plant and bolls per plant possessed maximum value of PCV% and GCV%. Maximum broad sense heritability (≥ 90) was found in all recorded traits except seeds per boll, fiber length and lint percentage. Correlation studies revealed that Seed cotton yield positively correlated with all yield contributing traits i.e. plant height, monopodial branches per plant, Number of bolls per plant, boll weight, lint weight, seed index, lint index, seeds per boll, fiber fineness, fiber strength and fiber uniformity at both genotypic and phenotypic level whereas it depicted negative relationship with staple length. Path coefficient analysis showed that maximum direct positive effect was found of lint weight (2.6005) on seed cotton yield followed fiber fineness (1.2628), seed index (1.1449) and bolls per plant (1.0027). Regression study exhibited that maximum value of R2 for lint weight (0.9509) and boll weight (0.3735) depicted that 95.09% and 37.35% variation in the seed cotton yield, due to its relationship with lint weight and boll weight. It is concluded that there is a great genetic potential in F3 populations for mostly yield contributing traits for further enhancing yield. So those traits should be used as selection criteria during breeding for yield.

The experiment comprised of 2 seasons (wet and dry), 2 practices (staked and unstaked), six cucumber varieties replicated three times in a Randomized Complete Block Design (RCBD). Planting distance was 75×75 cm. Insect pests, weeds, and fungi were controlled as recommended. Data collected were subjected to correlation and path effect analysis. In the dry season, the two practices revealed highly significant genotypic correlation (P<0.05) between fruit yield and vine length (rg= 1.20 and 1.07) and phenotypic (rp=0.69 and 0.74). With days to flowering, fruit yield displayed highly significant genotypic (rg=-1.14 and -1.03) and phenotypic correlation (rg=-0.74 and -0.76). In the wet season, the two practices revealed highly significant positive genotypic (rg=0.95 and 0.84) and phenotypic correlation (rg=0.84 and 0.71) between fruit yield and fruit length. Path analysis showed that high yield was achieved in the dry season through the maximum effect of fruit girth 0.34 and 1.15 in the two practices and shorter days to flowering -0.39. In the wet season, maximum fruit yield was obtained through fruit length (5.86 and 0.28) in both practices, in addition to less fruit girth (-6.76) and short days to flowering (-0.67).  In selection for high yields, the characters; vine length; fruit girth, fruit length and days to flowering can be utilized.

Authors: Jegadeeswari, C. Ushamalini K. Arunkumar, V.
Published: March 2019

Seed priming is one of the important method of seed treatment is the process of controlled hydration of seeds. At the time to a level that permits the pre-germinative metabolic activity, but that prevents actual emergence of the radicle is also known as pre germination seed treatment method. Seed priming is useful for increase the speed of seed germination and uniformity of germination particularly under adverse conditions like temperature, moisture and salinity. Seeds are soaked in different solutions like various inorganic salts, sugars and polyethylene glycol (PEG) a chemically inert, high molecular weight compounds, etc. After seed priming increase in hydrolytic enzyme activity especially a-amylase, strong increase of super oxide dismutase, catalase activities and expression of certain proteins related to water stress and heat shock. During germination the primed seeds contain higher scavenging of ROS (Reactive Oxygen Species). This reviews reported the primed spices seeds or rhizomes contain abiotic stress tolerant capacities, increase the antioxidant enzyme activities like peroxidase, catalase, superoxide dismutase (SOD), polyphenol oxidase (PPO), lipoxygenase (LOX) and phenyl alanine ammonia lyase (PAL), break the seed dormancy, increase the germination percentage and early growth. This studies gives an overview about the seed priming in spice crops with relevant case studies.

Published: March 2019

Many analytical procedures have been developed to determine the importance of phytohormones in different plants. The work reported here provides a sensitive, accurate and readily accessible gas chromatography coupled to mass spectrometry (GC-MS) technique designed for the simultaneous quantitation of phytohormones indole-3-aceticacid (IAA), abscisic acid (ABA), jasmonic acid (JA) and salicylic acid (SA). These signalling molecules were analysed in two different plants, Tomato and Tobacco grown in vitro. The protocol designed to assess the dynamic changes in endogenous concentrations of hormones to study plant responses to abiotic stresses in leaf tissues. A hormone profiling is obtained from leaves of plants exposed to salt stress show that different plant hormones are involved in diverse physiologicsl processes. Crosstalk between these hormones result in synergetic or antagonic interactions which have important roles to play in abiotic stress response.

Results showed that all the marked activity coefficients(biopotential) for the studied compounds are less than the standard drug, Ketoconazole.
En el Tolima sí hay afros: presencia y participación política de grupos afrocolombianos en Ibagué, Colombia
Authors: Forero Machado Sergio Andrés
Published: March 2019

Entender los procesos contemporáneos de comunidades afrocolombianas implica mirar a través del retrovisor para relacionar las causas históricas de laviolencia y exclusión que hoy viven. En los últimos años se han dado procesos migratorios de personas afrodescendientes a Ibagué, en medio de un contexto en el que lo urbano y lo rural están unidos en un ciclo. Por ello en esta ciudad tiene lugar un proceso organizativo de reivindicación de derechos que les han sido reconocidos ante la institucionalidad local en el marco de la formulación de una política pública. Frente a este proceso, como con muchos otros, los periodistas y los medios de comunicación presentan bastantes falencias en su quehacer periodístico, en relación a temas de comunidades negras/afrodescendientes. Por ello se plantean complejos retos para visibilizar las realidades y contextos de estas poblaciones.
ІДЕОЛОГІЧНІ ЗАСАДИ ЗАКОНОТВОРЕННЯ В ГАЛУЗІ ОСВІТИ
Authors: Simakova Nataliia Mykhailivna
Published: March 2019

Актуальність теми дослідження. Автор розглядає як внутрішні так і зовнішні пріоритети законотворення у галузі науки, що обомовлені загальною ідеологією, яка розпочалася з часів проголошення незалежності України, завдяки якій стали можливі демократичні зміни, розробка національної системи освіти, розроблена нова нормативно-правова база розвитку освіти.
Постановка проблеми. У контексті змін, які відбуваються в Україні, необхідно проаналізувати основні напрями та ідеологічні засади законотворення у галузі освіти, визначені Конституцією України.
Аналіз останніх досліджень і публікацій. Конституційно-правові засади доступу до освіти викликають значний інтерес серед науковців. В роботі ми звертаємо увагу на розвідки В. Андрущенка, В. Ковтунця, О.Сушинського, Д. Бондар, Л. Березовської.
Виділення недосліджених частин загальної проблеми. Реалізація рівного доступу до якісної освіти виявляється не простим завданням, це поняття носить «популістський» характер; особлива увага приділяється питанню, щодо обов’язкової загальної середньої освіти та «безоплатної» освіти.
Постановка завдання. Проводиться аналіз нормативно-правової бази в галузі освіти, яка розповсюджується для всіх громадян держави незалежно від національності, статі, соціального походження, місця проживання, майнового стану, віросповідання, стану здоров’я.
Виклад основного матеріалу. Етапи еволюції ідеологічних засад розвитку законодавчого процесу у галузі освіти прослідковуються у головних державних документах у галузі освіти, а саме, Державної програми «Освіта», Національної доктрини розвитку освіти, Концепції реформи «Нова українська школа», які детально розглядаються у даному дослідженні.
Висновки. Освіта є багатогранним та багатостороннім процесом, у якому мета і результат будуть досягнуті за умови системного підходу в нормативно-правовому забезпеченні.
Relationship intention and satisfaction as predictors of wholesale and retail customersâ€™ loyalty towards their training providers
Authors: Pelser C , Mostert P G
Published: March 2019

It is not surprising that service providers are increasingly attempting to establish customer loyalty as competition intensifies in service industries. Building long-term relationships and satisfying customer expectations could be an effective strategy to follow according to research that suggests strong relationships between customer relationships, customer satisfaction and customer loyalty. However, some researchers suggest that service providers should direct their marketing efforts only towards customers who have relationship intentions. It is thus essential for service providers to consider customersâ€™ relationship intentions and satisfaction when drafting strategies aimed at building customer loyalty. The purpose of this study was to determine the extent to which relationship intention and satisfaction predict customer loyalty within the wholesale and retail training sectors. Data were gathered from 185 wholesale and retail skills development decision-makers located across South Africa, who were involved in the selection of their organisationsâ€™ training providers. Using hierarchical multiple regression analysis, the fi ndings indicate that relationship intention and satisfaction significantly predict customer loyalty towards wholesale and retail training providers. Wholesale and retail training providers thus need to understand that establishing customer loyalty depends on their ability to develop strong relationships with customers who are receptive to relationship marketing efforts, and to ensure that these customersâ€™ needs are met.
