Total dissolved solids (TDS) and chlorophyll a were not related in 25 lakes which were all off the Precambrian Shield. Both on-shield and off-shield lakes were included in the previous reports which showed a significant relationship between TDS and productivity. When data from on-shield and off-shield lakes were analyzed separately, there was no significant positive relationship between TDS and lake biomass or productivity. It was also shown that mean depth ([Formula: see text]) was as good a predictor of fish production as the TDS: [Formula: see text] ratio, the morphoedaphic index.Key words: TDS, biomass, productivity, morphoedaphic index, chlorophyll a, lakes

Red Algal

An experiment was carried to assess the effect of red algal bloom on growth and production of carp, water quality and profit from carp for 120 days at Aquaculture Farm of Agriculture and Forestry University, Chitwan. The experiment included two treatments: carp polyculture in non-red pond and carp polyculture in red pond with algal bloom each with three replicates. Carp fingerlings were stocked at 1 fish/m2 and fed with pellet containing 24% CP at 3% body weight. Net yield of rohu was found significantly higher (p<0.05) in non-red ponds (0.38±0.01 t ha-1) than red ponds (0.24±0.05 t ha-1). Survival of rohu (84.9±1.4%), bighead (95.2±2.0%) and mrigal (88.1±14.4%) were also significantly higher (p<0.05) in non-red ponds than red ponds. Red algal bloom affected DO, nitrate and chlorophyll-a, nitrite, total nitrogen, total phosphorus, total dissolved solids and conductivity. However, overall carp production and profit from carp remained unaffected.

El tamaño es una variable contingente que puede influir en los resultados de las empresas. En este trabajo se pretende contrastar la existencia o no de una relación significativa entre tamaño y resultados empresariales de las empresas agrarias, en particular de las cooperativas hortofrutícolas españolas. Para ello, se realiza un estudio empírico en base a la información económica y financiera obtenida de los registros oficiales de las cooperativas agrarias dedicadas a la comercialización de frutas y hortalizas sobre el cual se ha aplicado un análisis de regresión. El estudio demuestra que no existe una relación significativa positiva entre los resultados empresariales y el tamaño de este tipo de entidades, por lo que se puede afirmar que la capacidad competitiva de una empresa agraria depende de su propia capacidad de gestión y no de un factor de contingencia como el tamaño. ABSTRACTSize is a contingency variable that can influence firms’ performance. This study aims to contrast whether exists or not a significant relationship between organizational size and performance in agrifood firms, particularly in the case of Fruit and Vegetables Cooperatives in Spain. Therefore, an applied empirical study using regression analysis is carried out from economic and financial information of such companies obtained from official registers. The study shows that there is not a significant positive relationship between performance and size for such type of firms. RESUMOO tamanho da cota é uma variável que pode influenciar os resultados das empresas. Este trabalho tem como objetivo contrastar a existência de uma relação significativa entre tamanho e desempenho dos negócios das empresas agrícolas, em especial as cooperativas hortícolas espanhóis. Para fazer isso, um estudo empírico é realizado com base em informações obtidas dos registros oficiais das cooperativas agrícolas que se dedicam à comercialização de frutas e legumes de informação económica e financeira sobre a qual foi aplicada uma análise de regressão. O estudo mostra que há uma relação positiva e significativa entre o desempenho da empresa e do tamanho de tais instituições, para que possamos dizer que a competitividade de uma empresa agrícola depende da sua própria capacidade de gestão e não um fator contingência como tamanho.

The present research is an explanatory research because the focus is to find out causal relationship between the exogenous and endogenous variables. Data were collected using the survey through questionnaires, which were sent directly by post. To speed up data collection, each district manager was contacted by the district office telephone. The data were also obtained from the airline magazine from district offices of each company in Surabaya. The research results have showed that there is a significant positive relationship between exogenous variables of the perceived environmental uncertainty on the endogenous variables of the efficiency orientation. There is no significant relationship between the perceived environmental uncertainty and the delegation of authority. There is no significant relationship between the perceived environmental uncertainty and suitability of accounting controls. There is a significant positive relationship between delegation of authority and manager performance. There is a significant and positive relationship between the suitability of accounting controls and manager performance. Efficiency orientation can act as variable that mediates relationship between the perceived environmental uncertainty and the delegation of authority and suitability of accounting control. The findings of this study are expected to contribute to the development of contingency theory in management accounting perticularly in the manager behavior in using management accounting information.

This chapter presents the results of a study on the influence of streamflow variability on salt fluxes in a semi-arid Tiva River Basin located in Eastern Kenya. Measurements of salinity, total dissolved solids (TDS), conductivity, and river discharges were undertaken in sampling stations located within the main branch of the river as well as in the tributaries, namely Kauwi, Kalundu, Nzeeu, and Mwitasyano Rivers in the Upper Region of the Tiva River Basin. The mean and maximum river discharges for the sub-basins of the river ranged from 11 to 33 m3s-1 and from 118 to 210 m3s-1, respectively. The peak river discharge at the main Tiva branch was 270 m3s-1. The study shows that there is a significant relationship between the variability of streamflow and the variability of salt fluxes in the river as exemplified by variation of salinity, conductivity, and TDS in the river.

Abstract Background Diabetes Distress is the understandable sense of burden or defeat that may occasionally punctuate the diabetic patient life. Also, Diabetes distress (DD) refers to the unique, often hidden emotional burdens and worries that are part of the spectrum of patient experience when man-aging a severe demanding chronic disease like diabetes. Objectives is to assess the relationship between Diabetes-related distress (using a Diabetes Distress Screening Scale) and the glycemic control (using A1C) and inflammation (using hs-CRP) in diabetic patients. Patients and Methods This study is a cross sectional study which had been carried out in outpatient clinic of endocrinology department of El Agouza Police Hospital during the period between June 2017 to June 2018.The study was done on 350 Type2 Diabetic patients.BMI,Wist/Hip Ratio, Fasting blood glucose,Post prandial blood glucose,HbA1c,hs-CRP,Creatinin,BUN,SGPT and SGPT were done to the patients, also Diabetes Distress Screening Scale Quastionnaire was completed by the patients. Results In this study we found that there is a highly significant positive relationship between HbA1c and both Fasting Blood Glucose and Post Prandial Blood Glucose. Also,there was a highly significant positive relationship between CRP and Fasting Blood Glucose while there was a non significant relationship between CRP and Post Prandial Blood Glucose.Fasting blood glucose and Post Prandial Blood Glucose showed a highly significant positive relationship with Total DDS score, Emotional burden and Physician realted distress, and showed non significant relationship with Regimen related distress and interpersonal distress.As regard the relation between HbA1c and Total DDS score, there was a highly significant positive relationship between them and also highly significant positive relationship between HbA1c and Emotional burden and physician related distress, but there was non significant relation between HbA1c and Regimen related distress and interpersonal distress. There was highly significant positive relationship between CRP and Total DDS score and also emotional burden, and there was significant positive relationship between CRP and Regimen related distress, and non significant relation between CRP and physician related distress and interpersonal distress. Conclusion In this study 350 type 2 diabetic patients were included. 55 diabetic patients show moderate distress with a highly significant relationship with the glycemic control (HbA1c) and significant relationship with CRP. In this age and sex were non significant factors while duration of diabetes, BMI and Wist-hip ratio show significant relation with HbA1c which reflect the glycemic control.

The major purposes of the study were to determine the extent of the problem faced by the farmers in bean cultivation and to explore the relationships between bean farmers’ selected characteristics with their problem faced. The study was conducted in four villages of two unions under Atghoria upazilla of Pabna District. Data were collected from a random sample of 106 bean farmers by using an interview schedule during 15 Dec, 2017 to 15 Jan, 2018. The highest proportion (71.70 percent) of the farmers faced medium overall problem in bean production, while 16.04 percent faced high and 12.26 percent faced low problem. Problem faced in non-availability of pesticides ranked 1st and this was followed by non-availability of fertilizers, lack of capital so on and least one lack of irrigation in bean cultivation ranked 28th. Correlation analysis indicated that education, training exposure, organizational participation, extension media contact and farmers’ knowledge had significant negative relationship with their problem faced. Age had significant positive relationship with their problem faced while family members, farm size, annual family income, bean cultivation area, and credit received by the farmers had no significant relationship with their problem faced. Overwhelming (87.74) majority of bean farmers faced medium to high problems therefore, it may be said that problem faced by the farmers in bean cultivation is a serious issue to be addressed to maximize bean production.Res.
