Authors: Vasudev Aparna , Francis Paul T.
Published: March 2019

Background: Mental health concern is escalating globally and current therapeutic approach is insufficient to bring people towards the state of mental well-being. There is a compelling need for effective population mental health promotion approaches. Yoga is a universally acclaimed method for promoting mental and physical well-being, but very much underutilised. The objective of the present study is to evaluate a community-based yoga training program which was conducted in the field practice area of a medical college in Ernakulam.Methods: A sequential mixed method-quantitative and qualitative-study was done among the participants who attended the yoga training. The perceived benefits of yoga and adherence to yoga were assessed using an investigator administered semi-structured questionnaire. Subsequently a focus group discussion was conducted among the study participants.Results: 20 subjects who attended the training participated in the study. Mean age was 48 years (SD±14.663) and 85% were females. Mean duration of yoga practice was 6 months. Among the participants, 95% continued yoga practice at home after the training. The main benefits reported were: a feeling of increased energy (75%), relaxed/happy feeling (55%), relief from body pain (40%) and stress reduction (35%).  The subjects reported that the increased energy they felt from yoga increased their work productivity and eased tiredness and stress.Conclusions: The study shows that yoga offers considerable benefits on mental health, with a large proportion of participants feeling energised and happier. Community based yoga training is a low cost and feasible approach for better mental health.

Authors: Moterle Silvete , Wernke Rodney , Junges Ivone
Published: March 2019

Algumas pesquisas relatam que os gestores das pequenas empresas têm dificuldades para utilizar instrumentos gerenciais da área financeira, o que pode ser influenciado pelo nível de conhecimento dos conceitos relacionados. Nesse sentido, o estudo teve o objetivo de identificar o nível de conhecimento sobre determinados conceitos financeiros por parte dos gestores de micro e pequenas empresas de uma microrregião do Sul de Santa Catarina. A pesquisa se caracteriza como descritiva, com abordagem quantitativa e utilização do procedimento survey para a coleta dos dados de 299 pequenas firmas. Após breve revisão da literatura e evidenciação de estudos anteriores, foram apresentados os dados levantados acerca do nível de conhecimento sobre os conceitos abrangidos. Os resultados destacam que ao menos 55% dos gestores possuem conhecimento sobre os conceitos pesquisados, mas esse contingente não ultrapassou os 75% em qualquer dos itens investigados. Dessumiu-se que o menor nível de conhecimento dos gestores se refere ao conceito de liquidez corrente. Por outro lado, os conceitos mais conhecidos pelos gestores estão vinculados à contabilidade financeira (Ativo Circulante, Passivo Circulante e Demonstração do Resultado). Outra constatação é de que os gestores das empresas industriais possuem nível de conhecimento mais elevado a respeito dos itens pesquisados quando comparados aos dirigentes das firmas comerciais e de serviços.

Published: March 2019

O estudo objetiva descrever os impactos causados pela rivalidade entre irmãos na gestão de empresas familiares. Realizou-se uma pesquisa descritiva por meio de estudo de caso e com uma abordagem qualitativa dos dados. Os resultados revelaram que a rivalidade já esteve presente na empresa familiar analisada desde seu processo sucessório em razão da diferença das quotas referentes à sociedade, e com o passar do tempo, começou a aflorar na empresa rivalidade entre irmãos e todos os demais membros. Por conta disso, começaram os questionamentos sobre a gestão, a desconfiança, o envolvimento de fatores externos e internos que influenciavam. Outro fator determinante para o aumento da rivalidade foi a presença das esposas na gestão da empresa familiar. Conclui-se que a rivalidade impacta de forma negativa os resultados das organizações familiares, especialmente nos casos que envolvem outras pessoas da família no negócio e que não conseguem separar a tríade (negócio, família e propriedade). A gestão é influenciada também pela falta de inteligência emocional dos membros, fazendo com que a organização sofra e apresente problemas, incluindo a dissolução.

Published: March 2019

The role of multinational enterprises (MNEs) for sustainable development, particularly in developing countries, has become a topic of debate among environmental, business, and economic researchers. In that context, we try to explore the compatibility and congruence of the business operations of MNEs vis-à-vis sustainable development in the developing part of the world. By using a multitheoretical framework followed with a multicase analysis concerning emerging and developing countries, we investigate how MNEs are addressing regional requirements of sustainable development where environment, local culture, and institutional mechanism are the key concerns. The adherence to evolving institutional mechanism over the years along with willful ethical steps taken by MNEs are found to be important in improving the state of affairs in the developing nations.
Effect of Carbon Dioxide Concentration on Cereal Yield in Sudan
Authors: Onour Ibrahim A. ,   School of Management Studies, University of Khartoum, Khartoum, Sudan
Published: March 2019

To estimate the long-term effect of carbon dioxide (CO2) emission on cereal yield in Sudan, we employed an autoregressive distributed lagged (ARDL) bound test for cointegration analysis. The ARDL results reveal evidence of cointegration between the dependent variable (cereals yield) and two independent variables (CO2 emission) and agricultural GDP. The estimation results of the error correction model indicate that change in CO2 has a positive and significant impact on the cereal yield in the long and short terms, as 1% increase in CO2 leads to a cereal yield increase by 3% in the short term and by 0.7% in the long term. This result adds two important findings to the existing literature: First, the positive impact of CO2 on cereal yield in Sudan supports previous research findings in other countries of warm and arid climates. Second, the effect of CO2 on cereal yield differs from short to long term, as our finding indicates that CO2 has a greater positive effect in the short term compared to that in the long term, implying that the effect of CO2 on cereal yields is not linear, as commonly perceived, but it decreases as time duration extends to longer periods. This may be due to the CO2 effect on global warming that emanates from cumulative CO2 concentration, which leaves a disproportionate impact on crops over time.

Published: March 2019

Long-term/chronic insomnia occurs in patients for over one month; it can affect the functions of the immune system and responses, which may involve cytokines. The aim was to determine alterations of Tumor necrosis factor alpha (TNF-alpha) and IL-10 cytokines in long-term insomnia. Thirty-three long-term/chronic insomnia patients (male, 22; female, 11) aged 47-61 years were initially recruited. Seven of them who were infected with microbial agents were excluded from the study. Of the 26 free of infectious agents only 21 (female, 5; male, 16) were successfully monitored. Age-matched apparently healthy non-insomnia subjects (male, 25; female, 25) free of the infectious agents were recruited as control. Plasma TNF-alpha, IL-10, HBsAg, anti-HCV, and HIVp24 antigen were assayed by ELISA method while determination of Mycobacterium tuberculosis was by Ziehl–Neelsen staining of sputum and Plasmodium spp. by thick blood Giemsa staining. Of the 33 insomnia patients initially recruited, 21.2% (7) were infected with microbial agents (Plasmodium spp., 6.1% (2); HCV, 3.0% (1); HBV, 6.1% (2); Mycobacterium tuberculosis, 3.0% (1); Plasmodium spp. + HBV, 3.0% (1); and HIVp24, 0). Twenty-one chronic insomnia patients were finally investigated on cytokines. There were significantly higher mean plasma values of TNF-alpha and IL-10 cytokines in chronic insomnia patients before treatment than the values obtained in the control subjects (p < 0.05). The results also showed a significantly lower mean plasma value of TNF-alpha cytokine in chronic insomnia patients after treatment than the values obtained in the patients before treatment. There were no significant differences in the mean plasma values of IL-10 cytokines in chronic insomnia patients before and after treatment (p > 0.05). There was a significant increase in plasma TNF-alpha and IL-10 cytokines in long-term insomnia patients before treatment while plasma TNF-alpha significantly decreased after treatment, and no significant difference was obtained in the plasma IL-10 before and after treatment. TNF-alpha could be a good investigative index of insomnia.

Authors: Journal Baghdad Science
Published: March 2019

A program in Visual Basic language was designed to predict the type of radio storm that emitted from Jupiter at specific Local Time (LT) from two different Iraqi locations (Baghdad and Basra), such storms result from the Central Meridian Longitude (CML) of system ??? for Jupiter and phase of Io’s satellite (?Io). Some of these storms are related to position of Io (Io- A,B,C,D) and others are unrelated (non-Io-A,B,C,D) to its position. The input parameters for this program were user specified by determining the observer’s location (longitude), year, month and day. The output program results in form of tables provides the observer with information about the date and the LT of beginning and end of each type of emitted storm. Two Io-storm ranges were used in this program according to the standard observations, one of them at year 2008 and the other one at 1976, the results according to year 2008 gave the observer more types of storms as compared with results that depending on 1976, these results indicated the type of storm is not changed for these two locations, but their LT was changed, because it depend on the location of the observer. The obtained results reveal a good agreement as compared with the results of (Radio Jove) software.

Theoretical Study of Thermal Cracking For Acenaphthylene Molecule
Authors: Journal Baghdad Science
Published: March 2019

Density Functional Theory (DFT) calculations were carried out to study the thermal cracking for acenaphthylene molecule to estimate the bond energies for breaking C8b-C5a , C5a-C5 , C5-C4 , and C5-H5 bonds as well as the activation energies. It was found that for C8b-C5a , C5-C4 , and C5-H5 reactions it is often possible to identify one pathway for bond breakage through the singlet or triplet states. The atomic charges , dipole moment and nuclear – nuclear repulsion energy supported the breakage bond .Also, it was found that the activation energy value for C5-H5 bond breakage is lower than that required for C8b-C5a , C5a-C5 , C5-C4 bonds which refer to C5-H5 bond in acenaphthylene molecule are weaker than C8b-C5a , C5a-C5 , C5-C4 bonds .It is reasonable to presume that C5-H5 bonds are broken first when a acenaphthylene molecule is exposed to thermal cracking. It seems that the characteristic planarity for the polyaromatic hydrocarbons is an important factor to acquire the molecule structure of the required stability along the reaction path . The trends in the bond energies and the configuration structures are discussed .

The aim of this study was spot light to the possibility of confection between hepatitis C&G viruses in Iraqi patients. The groups was studied included two groups as follow:
1- first group: its (Infected group) the patients of this group have Anti-HCV abs in their serum by using Indirect ELISA technique.
2- second group: its (Control group) the persons of this group have no Anti-HCV abs in their serum by using indirect ELISA technique.
The result of this study was observed there was two patients from the first group have Anti-HGVabs in their serum with infection percent 2.70%, also the same result was found in the second group wich mean there was two persons have Anti-HGVabs in their serum with infection percent 8.33% .So when we comparing these groups for obtained the confection between hepatitis Cand G virus the result was showed there was no significant differences between these groups( by using Qi-sequare).
Also when we study the effect of sex on HGV infection and prevalence the result was observed that the HGV infection was found in male but not in female and there is high significant differences when we compared the infection percent between diseased group and control group ( by using Qi-sequare).
The conclusion of this study there was no confection between HCV&HGV infection or there was a little or limited role in infection, and the sex factor play role in infection..

Let R be a commutative ring with identity 1 and M be a unitary left R-module. A submodule N of an R-module M is said to be approximately pure submodule of an R-module, if for each ideal I of R. The main purpose of this paper is to study the properties of the following concepts: approximately pure essentialsubmodules, approximately pure closedsubmodules and relative approximately pure complement submodules. We prove that: when an R-module M is an approximately purely extending modules and N be Ap-puresubmodulein M, if M has the Ap-pure intersection property then N is Ap purely extending.

Clouds Height Classification Using Texture Analysis of Meteosat Images
Authors: Journal Baghdad Science
Published: March 2019

In the present work, pattern recognition is carried out by the contrast and relative variance of clouds. The K-mean clustering process is then applied to classify the cloud type; also, texture analysis being adopted to extract the textural features and using them in cloud classification process. The test image used in the classification process is the Meteosat-7 image for the D3 region.The K-mean method is adopted as an unsupervised classification. This method depends on the initial chosen seeds of cluster. Since, the initial seeds are chosen randomly, the user supply a set of means, or cluster centers in the n-dimensional space.The K-mean cluster has been applied on two bands (IR2 band) and (water vapour band).The textural analysis is used where six parameters are calculated from the Co-occurrence matrix. These parameter were inserted in the K-mean. The best classifier feature is the angular second moment. When we use the angular second moment is used with any textural feature a good result were obtained for cloud classification, since the angular second moment gives indications on cloud homogeneity.

Authors: Journal Baghdad Science
Published: March 2019

The objective of this study was shed light for cultivation and maintenance of Trichomonas vaginalis parasite growth after isolated it by vaginal swaps from females suffering vaginitis and abnormal vaginal discharges in these media CPLM and TAB media to detect growth curve, morphological changes and viability of parasite in the two culture media, together with effect of sheep and bovine serum on the growth of it. The results of this studies were showed there was abtaine differences between the two types of media , The maximum growth of parasite was in TAB medium after 72 hours incubation with use of bovine serum, while such growth was maximized after 144 hours incubation with the use of sheep serum. In CPLM medium, a maximum growth was reached after 120 hours incubation in the case of sheep serum, and 168 hours incubation in the case of bovine serum. After less than 24 hours incubation, the parasite grew exponentially in TAB medium, but such growth was associated with an increased rate of death in contrast, the reverse picture was observed in CPLM medium. Through the stages of growth, the parasite manifested different morphological changes, which were ranged from a non-motile spherical shape, nucleated and flagellated pear shape, binucleated and flagellated spherical shape, slow-moving large spherical shape and finally the a flagellated spherical shape (pseudocyst).
