Rubber trees grow predominately in the southern and eastern areas of Thailand, where there is the majority of rainfall. However, the rubber tree plantations extend to north and northeastern areas, with lower annual rainfall. The aim of this study was to evaluate the effect of rainfall on growth of rubber tree in northeastern areas of Thailand. The outcome of this work should be helped to indicate the optimum area for rubber tree planting in northeast. The study was undertaken using rubber tree clone RRIM600 by comparing the girth at 150 cm at the soil surface, planted in areas of differing rainfall: in Nongkhai, Chaiyaphum, Khon Kaen, Roiet and Buriram provinces. The sample of 50 trees was selected in 3 plantations per province (150 trees per province). The results found that there was no significant difference in girth of the rubber trees in all areas. However, the rubber trees planted in Nongkhai, where had highest rainfall, had highest growth. Moreover, the relationship between rainfall and growth exhibited a positive correlation, demonstrating that higher rainfall increased the girth of rubber trees.

Objectives: Little is known about the relationship between core stability and shoulder dysfunction in shoulder impingement syndrome. The purpose of this study was to analyze the difference between healthy volunteers and patients with shoulder dysfunction in regard to core stability measures. Secondary purpose was to explore the relationship between measures of core stability and measures of shoulder dysfunction. Methods: 15 patients with shoulder impingement syndrome (mean age: 32.2±4.2 years) and 15 healthy volunteers (mean age: 33.8±6.2 years) participated in this study. Sorenson test, front plank and side bridge exercise was performed to assess anterior, lateral and posterior core endurance, respectively. Simple shoulder test (SSS) and seated medicine ball throw test was used to evaluate the functions of the shoulder joints. Mann-Whitney U test was used for comparison of variables between groups. Analyses of relationships between variables were examined with Spearman correlation test. Results: There was a statistically significant difference between patients with shoulder impingement syndrome and healthy controls in core stability and function (p<0.05). A strong positive correlation was found between shoulder functional test (SSS) and lateral bridge test (r= .874, p < .05). Additionally, a modest positive correlation was found between the SSS and the Sorenson test at (r= .695, p < .05), and a weak positive correlation was found between the SSS and the front plank test at (r= .365, p < .05). Conclusion: Core stability and functional deficiency was found in patients with subacromial impingement syndrome. According to this study, greater shoulder dysfunction is correlated with greater stability deficiency. Therapists should consider incorporating core strengthening as an integral component of rehabilitation program in patients with shoulder dysfunction.

In the present research an attempt was made to study the relationship between loneliness and depression among old aged people. The study was carried on by formulating hypotheses that (a)-There would be significant difference between loneliness and depression level of old aged people (b)-There would be positive correlation between loneliness and depression. For empirical verification of these two hypotheses a study was conducted on 60 old aged people of Patna and its neighboring places, by employing incidental-cum-purposive sampling technique. Their age ranged from 60 to 75 years. The UCLA Loneliness Scale was used for measuring loneliness. In order to check the level of depression in old aged people, Hindi adaptation of Beck’s Depression Inventory was applied. For the analysis of the obtained scores t-ratio and co-efficient of correlation were computed. The result confirmed all the hypotheses. The findings on the whole indicated that there is significant difference between loneliness and depression level of old aged people. Positive correlation between loneliness and depression level was also observed by the researcher. The findings of the present research reveal that loneliness plays an important role in determining depression among old aged people. Depression level can be reduced by reducing loneliness among old aged people.

Abstract Purpose: To analyze the changes of near binocular vision function after small incision lenticule extraction and association with asthenopia. Methods: This was a retrospective study．Twenty-five myopic patients who underwent small incision lenticular extraction (SMILE) surgery from Tianjin Eye Hospital were included in this study．The values of parameters of near binocular vision function were measured at preoperative, 1 week, 1 month and 3 months postoperatively including near heterophoria, near point convergence (NPC), horizontal base-in fusional reserves (BIFR) and base-out fusional reserves (BOFR). The patients were grouped by the preoperative symptoms scores. The comparisons among different follow-up periods were conducted by the repeated measures analysis of variance. The Pearson correlation coefficient (r) was used to evaluate the linear fit of the relationship between variables. Multiple linear regressions were used to analyze the relationship between asthenopia and parameters of binocular and accommodative function. Results: The NPC significantly increased at 1 week and 1 month after SMILE and then get back to the level of preoperatively in 3 months postoperatively. Near heterophoria significantly decreased at 1 week after SMILE and then remained stable in 3 months postoperatively. In the regression analysis, there was no significant association between the values of the fatigue questionnaire at different stages after SMILE operation and the parameters of near binocular visual function (P>0.05). However, there was significant positive correlation among each visit with the preoperative visual fatigue questionnaire（P<0.05). There was no significant difference in the parameters of binocular visual function between the normal group and the fatigue group. For the visual fatigue group, there was positive correlation between the score of visual fatigue questionnaire 1 week after SMILE surgery and the difference in near horizontal phoria between 1w postoperative and that preoperative (r=0.523, P=0.046), and significant negative correlation with the recovery point of BOFR at 1 week (r=-0.581, P=0.023). Conclusion: SMILE surgery wouldn’t influence the binocular vision in the short term. Since there was no significant association between binocular vision function and visual fatigue, factors of asthenopia in the early period of SMILE surgery should be further studied.

This study investigates the relationship between personality factors, leadership and organizational citizenship behaviour (OCB), predict changes in OCB by personality and leadership, and analyze the influence of demographic variables (organizational tenure, educational qualifications, age, designation, gender and job status) on OCB, personality, leadership and their dimensions. The sample consisted of 203 employees from three units of Sesa Goa Ltd., a leading mining company in Goa. Three reliable and valid tools were employed for the assessment-Organizational Citizenship Behaviour, NEO Five Factor Inventory and Leadership Effectiveness scale. Results of correlation analysis indicated positive correlation between leadership (all dimensions) and OCB. Of five personality factors, extraversion, agreeableness and conscientiousness showed positive correlation while neuroticism was found to be negatively correlated with OCB. Furthermore, result of regression analysis unveiled that 18% variance in OCB is contributed by leadership and 11% by personality. Unit wise differences were also evident in OCB. An incidental analysis using One Way ANOVA and t test revealed significant influence of organizational tenure and educational level on OCB. No significant difference was noticed on leadership and any of its dimensions. This study provides guidelines to aid managers better understand how to enhance OCB.

The study involving 2 pear cultivars was conducted in 2006–2016. ‘Radana’ and ‘Clapp’s Favourite’ were planted in the spring 2006 in the Experimental Station next to Wrocław (south-western Poland) on Quince S1 and Caucasian pear seedlings with 2 interstocks – ‘Doyenne du Comice’ and ‘Pyrodwarf’. An annual dose of 3 tonnes per hectare of Condit Basic bio-fertilizer was applied onto the tree row soil surface at the beginning of March 2012, i.e., starting from the 7th year after the planting. The study objective was to evaluate effect of Condit preparation on summer pear tree cultivars which are not compatible with Quince, and to assess interstock suitability in their context. The yields obtained in the first eleven years following tree planting were the most abundant for ‘Radana’ on Caucasian pear and on Quince with ‘Doyenne du Comice’ interstock. When applied for 5 years, Condit increased the leaf surface area, however a significant difference was exhibited only by ‘Radana’ on the Caucasian pear. This soil improver did not affect tree growth and yielding; total chlorophyll content; foliar Mg, P, Ca, and K; and mean fruit mass across the investigated treatment combinations.

Background: Previous research has indicated that there are significant sex differences in serum BDNF levels and metabolic indicators in patients with schizophrenia. Studies have found that BDNF is involved in blood sugar regulation. Homeostasis model assessment of insulin resistance (HOMA-IR) is currently a sensitive indicator for measuring insulin resistance. Our study aims to explore the sex differences in the relationship between serum BDNF levels and HOMA-IR in patients with chronic schizophrenia (CS).Methods: A total of 332 patients with CS were enrolled in this study. General information of all participants was collected. Haematological indicators were collected, and the Positive and Negative Syndrome Scale (PANSS) was used to evaluate psychiatric symptoms. Sex differences in serum BDNF levels, HOMA-IR index and other metabolic indexes were investigated. Then, linear regression analysis was used to analyse the relationship between the HOMA-IR index and BDNF levels in male and female patients.Results: The HOMA-IR index of female patients was significantly higher than that of males, but there was no significant difference in serum BDNF levels between male patients and female patients. There was a positive correlation between BDNF level and HOMA-IR index, and this relationship only existed in female patients.Conclusion: The results show that there are significant sex differences in HOMA-IR in patients with CS. In addition, only in female patients was there a positive correlation between the HOMA-IR index and BDNF level, which suggests that sex factors should be taken into account in evaluating the relationship between BDNF and blood glucose in patients with CS.

The purpose of the present study was to investigate the relationship among EFL teacher’s identity style, religious identity, and identity commitment. The data was collected from 88 EFL teachers teaching at different English language learning institutes in Ilam province- Iran. Two questionnaires were used, including Dollinger’s (2001) Brief Religiosity Scale (BRS-6) and Berzonsky’s (1992) Identity Style Inventory, the revised version (ISI3). Results suggested that EFL teacher’s identity style and their commitment were positively correlated (r = 0.350). There was also a significant positive correlation between EFL teacher’s religious identity and their commitment (r = 0.312). A significant positive correlation was also found between EFL teacher’s identity style and religious identity (r = 0.367).  The results of one-way ANOVA indicated that there was a statistically significant difference in identity style scores, identity commitment scores, and religiosity scores for four groups. The results of independent t-test analysis indicated that there was no significant difference in identity style, identity commitment, and the religiosity scores of the two groups of participants. Finally, the implications and limitations of the study were also discussed.

Broomrapes (Orobanche spp.) are chlorophyll-lacking root parasites of many dicotyledonous species that cause severe damage to vegetables and field crops worldwide. Egyptian broomrape is common throughout Israel, where it parasitizes a wide range of crops. The main damage caused by this parasite is to processing tomatoes. The objectives of this study were to determine (1) the relationship between the parasitism process on tomato roots and Egyptian broomrape seed depth, and (2) the effect of herbicide application on Egyptian broomrape control at depths of 0 to 30 cm. The study was conducted in controlled conditions in 25-L pots containing soil that was artificially infested with Egyptian broomrape seeds. Seeds (1-cm layer) were infested at soil surface and at depths of 6, 12, 18, 24, and 30 cm. Sulfosulfuron was applied PRE to Egyptian broomrape shoots, 14 and 42 d after tomato planting. Egyptian broomrape emergence was highly correlated to the depth of the seed infestation: the deeper the seeds were buried, the more pronounced the delay in Egyptian broomrape emergence. A four-parameter sigmoid equation was found that describes the relationship between Egyptian broomrape parasitism and seed depth. No Egyptian broomrape shoots were observed aboveground when sulfosulfuron was applied on tomato foliage. However, live and dead attachments were observed at different levels in all seed-depth treatments. No significant difference in the efficacies of sulfosulfuron at rates of 37.5 and 75 ai ha−1 was observed at depths of 6, 12, and 18 cm. The best control was obtained at a depth of 6 cm at both sulfosulfuron rates. At depths of 24 and 30 cm, no broomrape control was achieved at 37.5 ai g ha−1 sulfosulfuron, and only low control efficacy was obtained at 75 ai g ha−1.

Aims and Background To evaluate the function and distribution of BAG-1 protein in hyperplastic and neoplastic prostate tissue and establish the relationship between this protein and BCL-related proteins (BCL-2 and BAX), androgen receptor (AR) expression and chromogranin A. Methods Twenty-eight prostatic adenocarcinomas and 16 prostate hyperplasias were included in this retrospective study. BAG-1, BCL-2, BAX, androgen receptor and chromogranin A immunostaining was performed by means of standard avidin-biotin peroxidase methods. The M30 antibody was used to identify preapoptotic and apoptotic cells. The immunohistochemical histological score (HSCORE) semi-quantative system was used to evaluate immunohistochemical staining. Results Statistical analysis showed a significant difference in HSCOREs of BAX, M30 and AR between the carcinoma and hyperplasia groups. Carcinomas expressed higher HSCOREs of these markers than hyperplasias. There were significant differences in nuclear and cytoplasmic BAG-1 positivity between high and low-grade carcinomas. BAG-1 expression was higher in low-grade carcinomas. In the carcinoma group there was a positive correlation (Pearson) between BCL-2 and cytoplasmic/nuclear BAG-1. In the hyperplasia group there was a negative correlation between BAX and BCL-2, and between AR and M30. We also detected a positive correlation between AR and nuclear/cytoplasmic BAG-1 and between nuclear and cytoplasmic BAG-1 in hyperplasias. BAG-1 showed the same specific basal cell localization as BCL-2 in hyperplastic and normal glands. Conclusions The BAG-1 protein showed a distinct distribution pattern in hyperplastic and neoplastic prostate. BAG-1 in association with BCL-2 inhibits apoptosis and may prolong the life of neoplastic cells and give them a chance to gain new oncogenic features in early carcinogenesis.

The Relationship

From a consideration of the distribution of species and species groups in relation to soil and climatic factors, it is shown that mean annual rainfall and mean maximum January temperature largely explain the distribution pattern of arid zone soil surface lichens. A past distribution of lichen crusts in southern Australia is postulated on the basis of factors controlling lichen crust development, and known variations from this pattern explained in terms of stocking history.
