Authors: Takdir Mohammad
Published: November 2017

This paper aims to elaborate the therapy power of gratitude in the shaping of the altruistic personality. This research used a comparative study of quranic psychology and positive psychology as a reference to explain about therapy power of gratitude. This research used a psychological approach to reveal the influence of the grateful on the meaningfulness of life.The results showed grateful in quranic psychology is a form of recognition of the favors bestowed by God with the submission and obedience according to what has been commanded. Gratitude in quranic psychology can be practiced in the three ways, namely orally grateful, heart, and deed. Gratitude in positive psychology is an emotional positive reaction in response to the receipt of a gift and benefit from someone. Gratitude in this perspective can be practiced personally (be thankful to the people who has given a gift) and transpersonal (expression of gratitude to God who has given many gifts in this world). In quranic psychology, be grateful can be Sufi healing or therapy to cure individualistic attitude into the life of the society. In positive psychology perspective, becoming a thankful person tend to be more generous and humble, if compared with those who never grateful.

Tulips are one of the important bulbous flowers and valuable as cut flowers. Hence, the present experiment was conducted in order to study effect of different concentrations of gibberellic acid (GA), light sources, and cold storage time on tulip flowers. The results of the present study revealed that day to sprouting and flowering of tulip decreased by T1×G2B, and T1×G2B and T2×G2B conditions, respectively. Plant height as well as the first internode length was also increased at T1×CD and T2×CD conditions. Furthermore, all light treatments, except of the dark conditions, enhanced the amount of anthocyanin and chlorophyll content of tulips plants. Similarly, the same trend recorded for dry weight of leaf and bulb of tulip. In conclusion, application of different light qualities in combination with GA and cold storage treatments resulted in an improvement in the growth parameters as well as the morphological and the flowering characteristics of tulip.

Authors: Benider C. , Madani T. , Bouzerzour H. , Guendouz A.
Published: November 2017

A Field experiment was carried out during the 2015-2016 growing season at Sersour experimental farm, located in the semi-arid region of Sétif (Algeria). The aim of this study was to evaluate the efficiency of using the numerical image analysis approach to estimate biomass and senescence by mean of appropriate software, the Mesurim Pro (Version 3.3). The results showed a significant difference between leaf reflectance at Red, Green and Blue light; results also registered a positive and significant correlation between leaf reflectance at red and blue, and senescence (r=0.78, r=0.50, respectively). This relationship between senescence and leaf reflectance indicate that the increase in leaf reflectance during senescence stage is due to degradation of leaf chlorophyll content. Over all, the numerical image analysis was very suitable approach to estimate reflectance of vegetal cover and the variation of some physiological traits.

Authors: Shashikumar R. , Krishna V. , . Venkatesh , Lokesha S.
Published: November 2017

In the present study, the genetic variations of leaf calli regenerants of Musa paradisiaca cv Karibale-Monthan has been analyzed using AFLP markers. The highest (86.66%) frequency of compact callus formation was obtained when leaf explants were cultured on MS media, containing 3mg/L 2,4-D and 0.5 mg/L BAP. The optimum shoot formation and multiplication (5.70±1.49) was achieved from the leaf derived callus on MS medium fortified with 3mg/L BAP+0.5mg/L TDZ. The 3-4 cm small shoots produced distinct roots on MS media containing 0.5mg/l NAA with 0.2% activated charcoal. The AFLP analyses produced 1012 monomorphic bands from total 1094 bands with 7.5% polymorphism between mother plant and callus derived regenerants. The percentage of monomorphism for individual primer combinations was very high and varied from 90.3% (EcoRI-AG×MseI-CCG) to 97.6% (EcoRI-AT×MseI-CGA). The result showed lack of polymorphism is due to genetic integrity of the plants that was not altered indifferent to the hormonal treatment.

Published: November 2017

Sclerotium rolfsii Sacc, a soil-borne pathogen causing root rot, stem rot, wilt and foot rot diseases in most of agricultural and horticultural crops. When the fungus completes its life cycle, sclerotia are formed on the plant parts including stems and roots of sunflower which is main source of disease development in next crops. Sclerotia of S.rolfsii survived in field soil depending on soil type, soil microorganisms and environmental conditions of particular geographical area,. Keeping this in view, experiment on viability of sclerotia of Sclerotium rolfsii at different depths and time durations in soil was conducted under screen house and field conditions at research farm of CCS, Haryana Agricultural University, Hisar. Sclerotia of Sclerotium rolfsii obtained from infected stems and roots of sunflower plants were wrapped in synthetic nets and buried at different depths and durations. Results showed that viability of sclerotia declined gradually in screen house and sharply under natural field conditions with the increase in soil depth and time duration of burial. None of the sclerotia germinated, when placed at 15 cm depth in soil after eight month of burial as compared to 55.75 per cent germination at same depth after one month of burial under screen house conditions. None of the sclerotia germinated, when placed from 0-15 cm soil depth after nine month of burial under field conditions.

Fear of China: Economic and Political Challenge in the 21st Century: A Pacific Society, Weapons, Roots and Trends
Authors: Caldararo Niccolo
Published: November 2017

While the world has been distracted since the American war in Vietnam and the Soviet and western adventures in Afghanistan, as well as a rising tide of rebellion directed against symbols of the west by Islamic fundamentalists, a curious contest has appeared on two fronts: Russia and China. At the same time the west is distracted by populist movements whose theme is focused on immigrants from former colonial nations or non-whites in a context, as in America, where aboriginal peoples have been slaughtered and marginalized. The specific nature of this conflict is economic in general form, yet political in rhetoric, especially from western sources. From the Ukraine to the Pacific a kind of “Phoney War” has crept along in starts and stops with overtures of friendship interrupted with threats of violence and minor acts of aggression. Investigation of some of the underlying factors in the East illuminate potential trends for the future. At the same time a new revitalization movement is reshaping the Anglo-American west, one that challenges the role of China in trade and policy.

Authors: Matos Maciel Harine , Maciel Wlisses Matos
Published: November 2017

A concessão de crédito tornou-se uma das principais operações dos bancos pós-estabilização econômica. O setor bancário busca uma melhoria na análise de concessão de crédito, pois existe o risco das pessoas não honrarem seu compromisso com a instituição financeira. É fundamental que haja um acompanhamento das operações para garantir o retorno dos empréstimos concedidos. Desta forma, o objetivo do trabalho foi analisar os principais fatores que determinam a inadimplência de clientes de um banco comercial em um município da região metropolitana de Fortaleza. Para analisar a probabilidade de inadimplência do cliente, foi construído um modelo com o objetivo de identificar relações significantes entre a variável dependente (probabilidade de inadimplência) e as variáveis explicativas (estado civil, tempo de conta, grau de instrução, idade, sexo e renda).Os principais resultados obtidos foram que ambos os sexos possuem participações semelhantes no setor bancário, a idade média dos clientes é de 47 anos, a escolaridade concentra-se no ensino médio e superior completo, a renda de mais de 50% dos clientes é maior ou igual a cinco salários mínimos e 66,78% dos clientes da agência estudada estão adimplentes. Para analisar a probabilidade de inadimplência do cliente, foi construído um modelo com o objetivo de identificar relações significantes entre a probabilidade de inadimplência e o estado civil, tempo de conta, grau de instrução, idade, sexo e renda. Os coeficientesque mais influenciaram a probabilidade de inadimplência foram os das variáveis: tempo de conta, idade, grau de instrução e renda. Os resultados demonstraram não haver relações significantes entre todas as variáveis estudadas. Apesar disso, acredita-se que os resultados deste trabalho devem ser aprofundados através de estudos posteriores para tornar possíveis conclusões definitivas quanto à relação entre as principais variáveis utilizadas na gerência de risco de um cliente bancário.

The Efficacy of Electronic Health�Supported Home Exercise Interventions for Patients With Osteoarthritis of the Knee: Systematic Review (Preprint)
Authors: Schäfer Axel Georg Meender , Zalpour Christoff , von Piekartz Harry , Hall Toby Maxwell , Paelke Volker
Published: November 2017

BACKGROUND

Osteoarthritis of the knee is the most common cause for disability and limited mobility in the elderly, with considerable individual suffering and high direct and indirect disease-related costs. Nonsurgical interventions such as exercise, enhanced physical activity, and self-management have shown beneficial effects for pain reduction, physical function, and quality of life (QoL), but access to these treatments may be limited. Therefore, home therapy is strongly recommended. However, adherence to these programs is low. Patients report lack of motivation, feedback, and personal interaction as the main barriers to home therapy adherence. To overcome these barriers, electronic health (eHealth) is seen as a promising opportunity. Although beneficial effects have been shown in the literature for other chronic diseases such as chronic pain, cardiovascular disease, and diabetes, a systematic literature review on the efficacy of eHealth interventions for patients with osteoarthritis of knee is missing so far.

OBJECTIVE

The aim of this study was to compare the efficacy of eHealth-supported home exercise interventions with no or other interventions regarding pain, physical function, and health-related QoL in patients with osteoarthritis of the knee.

METHODS

MEDLINE, CENTRAL, CINAHL, and PEDro were systematically searched using the keywords osteoarthritis knee, eHealth, and exercise. An inverse variance random-effects meta-analysis was carried out pooling standardized mean differences (SMDs) of individual studies. The Cochrane tool was used to assess risk of bias in individual studies, and the quality of evidence across studies was evaluated following the Grading of Recommendations, Assessment, Development, and Evaluation approach.

RESULTS

The literature search yielded a total of 648 results. After screening of titles, abstracts, and full-texts, seven randomized controlled trials were included. Pooling the data of individual studies demonstrated beneficial short-term (pain SMD=−0.31, 95% CI −0.58 to −0.04, low quality; QoL SMD=0.24, 95% CI 0.05-0.43, moderate quality) and long-term effects (pain −0.30, 95% CI −0.07 to −0.53, moderate quality; physical function 0.41, 95% CI 0.17-0.64, high quality; and QoL SMD=0.27, 95% CI 0.06-0.47, high quality).

CONCLUSIONS

eHealth-supported exercise interventions resulted in less pain, improved physical function, and health-related QoL compared with no or other interventions; however, these improvements were small (SMD<0.5) and may not make a meaningful difference for individual patients. Low adherence is seen as one limiting factor of eHealth interventions. Future research should focus on participatory development of eHealth technology integrating evidence-based principles of exercise science and ways of increasing patient motivation and adherence.

BACKGROUND

Multiple choice questions represent one of the commonest methods of assessment in medical education. They believed to be reliable and efficient. Their quality depends on good item construction. Item analysis is used to assess their quality by computing difficulty index, discrimination index, distractor efficiency and test reliability.

OBJECTIVE

The aim of this study was to evaluate the quality of MCQs used in the college of medicine, King Khalid University, Saudi Arabia.

METHODS

Design:
Cross sectional Study design
Setting, Materials and methods
Item analysis data of 21 MCQs exams were collected. Values for difficulty index, discrimination index, distractor efficiency and reliability coefficient were entered in MS excel 2010. Descriptive statistic parameters were computed.

RESULTS

Twenty one tests were analyzed. Overall, 7% of the items among all the tests were difficult, 35% were easy and 58% were acceptable. The mean difficulty of all the tests was in the acceptable range of 0.3-0.85. Items with acceptable discrimination index among all tests were 39%-98%. Negatively discriminating items were identified in all tests except one. All distractors were functioning in 5%-48%. The mean functioning distractors ranged from 0.77 to 2.25. The KR-20 scores lie between 0.47 and 0.97

CONCLUSIONS

Overall, the quality of the items and tests was found to be acceptable. Some items were identified to be problematic and need to be revised. The quality of few tests of specific courses was questionable. These tests need to be revised and steps taken to improve this situation.
Relaciones entre formación disciplinar, concepciones sobre el aprendizaje y uso de estrategias metacognitivas en estudiantes universitarios de profesorado
Authors: García María-Basilisa , Vilanova Silvia-Lucía , Señoriño Orlanda-Angélica , Medel Gisele-Anahí , Natal Marcela
Published: November 2017

Detrás de las acciones y estrategias de las personas para aprender o enseñar, existe un cuerpo teórico no explícito, que se configura a partir de un conjunto de supuestos coherentes o incoherentes entre sí, en función de la relación que exista entre lo que el sujeto dice y lo que hace. Estas representaciones implícitas surgen no sólo de la educación formal recibida, sino de la propia historia educativa de cada sujeto y, en el caso de los docentes, orientan de un modo u otro su práctica, tal como lo indican numerosas investigaciones sobre el tema. En este trabajo se analizan las concepciones sobre el aprendizaje y la utilización de estrategias metacognitivas de dos grupos de estudiantes universitarios de profesorado, provenientes de distintas áreas disciplinares: ciencias humanas y ciencias exactas.  Los resultados muestran dependencia de las concepciones de aprendizaje con respecto al dominio de formación disciplinar, situación que se da sólo parcialmente en el caso de la utilización de estrategias metacognitivas.

Thermodynamic analysis, using the exergy or entropy methods, is usually carried out for better insight into the physical meaning of the losses encountered in a cryogenic plant. From the results of such analysis, it is possible to evaluate the individual efficiencies of the various processes and to identify those calling for an improvement. It is also possible to determine thermodynamic efficiency of the cycle as a whole. The technique involves determination of entropy changes or exergetic losses in each of the processes making up the cycle. Based on the exergy analysis, it has been possible to evaluate specific work requirement, overall thermodynamic efficiency, Specific cooling capacity, work requirement per kg of liquid nitrogen product and coefficient of performance of the turbo expander cryogenic cycle using hydrogen and helium as the refrigerant.

The fluid-flow and heat transfer in a buoyancy-driven microcavity heated from below are numerically investigated. In spite of the fact that microcavities are widely used in microelectro- mechanical systems, now a day, more interest in the evacuated cavity on Eqn. solar collectors are very common to reduce heat loss from the system. This paper provides a useful information for engineers to estimate heat transfer in low pressure cavities. The finite volume technique was used to solve the governing equations along with temperature jump and slip flow boundary conditions.The simulations are carried out for various cavity aspect ratios (H/L) and different Rayleigh number for both macroand micro-fluids. The effect of Knudsen number in the rarefied flow regime (microfluidic) has also been investigated. It is shown that for both cases the effect of aspect ratios on heat transfer becomes significant at high Rayleigh numbers and when the aspect ratio is below 5. It was also found that increasing Knudsen number reduces the heat transfer. The interaction between Nusselt, Rayleigh, Knudsen numbers, and the aspect ratio was investigated using the design of experiments, results show that no interaction between these parameters. To help engineers to estimate heat transfer in low pressure cavities, widely used in solar energy applications, a correlation for convection heat transfer coefficient is introduced.

The condenser plant has a huge impact on the economy of a steam turbine power
plant. Deterioration of the parameters during operation could lead to a
significant decrease in electrical output and to an increase in the heat
rate of the thermal power plant. Detailed calculations of the performance
under different operating conditions were carried out for the condenser of
the Morava thermal power plant. Comprehensive testing of the condenser was
carried out and experimental data were compared with the numerical results.
The effects of deviations in the condenser behaviour on the main
thermodynamic parameters and the overall economics of the power plant were
evaluated. Guidelines for operation of condensation plants are given in the
conclusion.

OBJECTIVE To assess the effect of decreased platelet and WBC counts on platelet aggregation as measured by a multiple-electrode impedance aggregometer in dogs.

ANIMALS 24 healthy dogs.

PROCEDURES From each dog, 9 mL of blood was collected into a 10-mL syringe that contained 1 mL of 4% sodium citrate solution to yield a 10-mL sample with a 1:9 citrate-to-blood ratio. Each sample was then divided into unmanipulated and manipulated aliquots with progressively depleted buffy-coat fractions such that 2 to 3 blood samples were evaluated per dog. The Hct for manipulated aliquots was adjusted with autologous plasma so that it was within 2% of the Hct for the unmanipulated aliquot for each dog. All samples were analyzed in duplicate with a multiple-electrode impedance aggregometer following the addition of ADP as a platelet agonist. The respective effects of platelet count, plateletcrit, Hct, and WBC count on platelet aggregation area under the curve (AUC), aggregation, and velocity were analyzed with linear mixed models.

RESULTS WBC count was positively associated with platelet AUC, aggregation, and velocity; blood samples with leukopenia had a lower AUC, aggregation, and velocity than samples with WBC counts within the reference range. Platelet count, plateletcrit, and Hct did not have an independent effect on AUC, aggregation, or velocity.

CONCLUSIONS AND CLINICAL RELEVANCE Results indicated that WBC count was positively associated with platelet aggregation when ADP was used to activate canine blood samples for impedance aggregometry. That finding may be clinically relevant and needs to be confirmed by in vivo studies.
