análisis de modelos causales. Principios básicos del método Simon- Blalock
Authors: Cobas José A.
Published: November 2022

José A. Cobas, científico social de reconocido prestigio en Estados Unidos y en Latinoamérica, nos presenta la aplicación de un modelo de análisis social, según el método de Simón-Blalock. El modelo matemático que nos ofrece contribuye a determinar las relaciones causales de las diversas variables. No es un sustituto de la teoría, como tampoco ésta lo puede ser del método empírico. Como concluye el autor: "A pesar de su elegancia matemática, los modelos causales reflejan la agudez teórica del investigador; el pensamiento teórico indisciplinado crea modelos pobres; los modelos causales son un instrumento útil, pero no un sustituto de la teoría".

Published: November 2022

This paper presents multinomial logistic regression and neural network models that allow predicting and thereby quickly determining the content of nitrate nitrogen in the 0-40 cm soil layer before sowing. To train the models, we used the data of a long-term multifactorial field experiment of the Siberian Research Institute of Agriculture and Chemistry of the Siberian Federal Scientific Research Center of the Russian Academy of Sciences for 2009-2018, established in 1981 on leached chernozem in the OS "Elitnaya" - a branch of the Siberian Federal Scientific Research Center of the Russian Academy of Sciences. Taking into account the features of the statistical sample (observation data and analyses), the main predictors of the models that affect the content of nitrate nitrogen in the soil (target indicator) are determined, they are presented qualitative (predecessor, tillage) and quantitative (weather conditions and the content of productive moisture before sowing in the layer 0-100 cm) by factors with appropriate gradations. The models showed a fairly high reliability when verified on empirical data and can be used as a tool for forecasting. The quality of the developed multinomial logistic regression model was assessed using the coefficient of determination, which was 78% according to the Nagelkerke measure, and 72% according to the Coxsei Snell measure. To determine the predictive ability of the neural network, an ROC analysis was carried out, which showed that the area under the ROC curve for each category of the target indicator was close to 1, which indicates a high predictive power of this method. A comparative assessment of the predictive capabilities of the trained models was carried out. The overall proportion of correct predictions for multinomial logistic regression is 80.6%, in the neural network model 89.5%.

CASE STUDY PROTOCOL FOR QUALITATIVE RESEARCH IN OPERATIONS MANAGEMENT
Authors: Lopes Guerra João Henrique
Published: November 2022

In operations management field, researches that adopt the case study method are often criticized for lack of rigor. That is worrisome, considering the popularity of this method. Achieving rigor requires some actions from the researcher and one of them is the adoption of a robust research protocol. However, information about the case study protocol is fragmented in literature; in fact, many studies address the method, but those dealing specifically with protocol are scarce. Aiming to assist other researchers, in this study is proposed a case study protocol for qualitative researches in operations management that can be applied in any type of case study, especially in those that study organizations and their internal processes and adopt the interview as the main source of information. The proposal is the result of a protocol tested in the field and an extensive literature review covering different areas of knowledge (focusing on the most classic and important papers on the subject). The protocol was replicated eighteen times in a study about an important organization and evaluated by six researchers in different phases. It comprises a set of recommendations and should be used as a reference guide on how to proceed in data collection step. If planned and used with care, the protocol will guide the researcher, favoring the rigor and quality of the results, eliminating doubts and uncertainties and reducing reworks.
Large Simulated Future Changes in the Nitrate Radical Under the CMIP6 SSP Scenarios: Implications for Oxidation Chemistry
Authors: Archer-Nicholls Scott , Allen Rachel , Abraham Nathan Luke , Griffiths Paul Thomas , Archibald Alexander Thomas
Published: November 2022

Abstract. The nitrate radical (NO3) plays an important role in the chemistry of the lower troposphere, acting as the principle oxidant during the night. Previous model simulations suggest that the levels of NO3 have increased dramatically since the pre-industrial. Here, we show projections of the evolution of the NO3 radical from 1850–2100 using the UKESM1 Earth System model under the CMIP6 SSP scenarios. Our model results highlight diverse trajectories for NO3, with some scenarios and regions undergoing rapid growth of NO3 to unprecedented levels over the course of the 21st Century, and others seeing sharp declines. The local increases in NO3 are driven not only by local changes in emissions of nitrogen oxides but have an important climate component, with NO3 being favoured in warmer future climates. The changes in NO3 lead to changes in the oxidation of important secondary organic aerosol precursors, with potential impacts to particulate matter pollution regionally and globally. This work highlights the potential for substantial future growth in NO3 and the need to better understand the formation of SOA from NO3 to accurately predict future air quality and climate implications.
Comparison of calibration characteristics of different acoustic impact systems for measuring bedload transport in mountain streams

Published: November 2022

Abstract. The Swiss plate geophone (SPG) system has been installed and tested in more than 20 steep gravel-bed streams and rivers, and related studies generally resulted in rather robust calibration relations between signal impulse counts and transported bedload mass. Here, we compare this system with three alternative surrogate measuring systems. A variant of the SPG system uses the same frame (housing) set-up but with an accelerometer instead of a geophone sensor to measure the vibrations of the plate (GP-Acc, for geophone plate accelerometer). The miniplate accelerometer (MPA) system has a smaller dimension of the impact plate and is embedded in more elastomer material than the SPG system. The Japanese pipe microphone (JPM) is a 1 m long version of the system that has been installed in many streams in Japan. To compare the performance of the four systems, we used calibration measurements with direct bedload samples from three field sites and an outdoor flume facility with controlled sediment feed. At our field sites, the systems with an accelerometer and a microphone showed partly large temporal variations in the background noise level, which may have impaired the calibration measurements obtained during certain time periods. Excluding these periods, the SPG, GP-Acc, and JPM all resulted in robust
calibration relations, whereas the calibration of the MPA system showed a
poorer performance at all sites.

Published: November 2022

Abstract. The design, characteristics, and performance of a CubeSat magnetometer board (Quad-Mag) equipped with four PNI RM3100 magnetometers is presented. The low size, weight, power, and cost of the RM3100 enables the inclusion of four sensors on a single board, allowing a potential factor of 2 reduction in the noise floor established for an individual sensor via oversampling with multiple sensors. The instrument experimentally achieved a noise floor of 5.34 nT (individual axis), averaging across each axis of the four magnetometers, at a 65 Hz sampling rate. This approaches the theoretically established limit for the system of 4.37 nT at 40 Hz. A single onboard Texas Instrument MSP430 microcontroller handles synchronization of the magnetometers and facilitates data collection through a simple UART-based command interface to a host system. The Quad-Mag system has a mass of 59.05 g and total power consumption of 23 mW while sampling and 14 mW while idle. The Quad-Mag enables nearly 1 nT magnetic field measurements at 1 Hz using commercial off-the-shelf sensors for space applications under optimal conditions.
Library Environmental Conditions and Undergraduates’ Patronage of Public University Libraries in Delta State, Nigeria
Authors: Rachael Ejovwokoghene Eserada
Published: November 2022

The university library is basically setup to make available information resources and service to their users, patronage of the library, therefore, is the major reason for the existence of the library. The study examined the association between undergraduate library use at Delta State and the characteristics of the different types of library environments. To examine the questionnaire survey was developed to collect data from 272 library users. According to the report, public university library facilities have inadequate environmental conditions. Undergraduates expressed a high level of satisfaction with the design and surroundings of their university libraries. Most respondents seldom patronise the university library’s materials and services. The study equally made bare that substantial correlation exists between the kind of library environmental circumstances and undergraduates’ patronage of public university libraries, patronage of library resources/services was minimal. The study concluded that the prevailing library environment conditions influenced undergraduate patronage of public university libraries in Delta States. As a result, it was advised that the library management should implement necessary strategies to establish and maintain a calm and welcoming library environment. It was equally advised to utilise all available strategies, including regular orientation and word-of-mouth marketing of library resources/services, as this can significantly encourage an increase in patronage of the university libraries.
Economically Prudent Design (EPC) of Outrigger-Based Structural Systems
Authors: Kuckian Sachin , Yahia Hussin
Published: November 2022

As the construction of mega-tall buildings in all major cities around the world accelerates, the seismic risk associated with them also rises. Hence study on the response of tall buildings to earthquake loads is gaining significant importance. Outrigger tall buildings are one of the most common structural structures because they are simple to construct, cost-effective, and have significant lateral stiffness. Therefore, this research explores a structural outrigger system for high-rise buildings to analyze the output of a system by changing the place of outrigger positions. Dynamic research was performed in accordance with IS 1893, the response spectrum and time of California’s most recent earthquakes. The parameters discussed are lateral displacements, inter-storey drifts for static analysis, and base force, displacement, and spectral acceleration for dynamic analysis. From the analyzed results, it was found that an outrigger when located at H0/H=0.6 causes a maximum reduction in the lateral displacement. Hence outrigger located at H0/H=0.6 is the desired location to provide an outrigger in a structural system and could act as an initial economical prudent design solution in the construction of tall buildings with outriggers. Time history analysis shows that the reduction is maximum when the outrigger is located at H0/H=0.9 for LA03, H0/H=0.85 for LA06 H0/H=1.0 for LA14.

Актуальность данного исследования состоит в важности обеспечения безотказной работы системы заякорения дорогостоящих плавучих сооружений. При любых внешних воздействиях система удержания должна обеспечить продолжение нормальной эксплуатации плавучего объекта. Это предложено достигнуть путем определения основных параметров данных систем статическими расчетами. Целью исследования является рассмотрение имеющихся подходов и методов расчета заякорения плавучих сооружений и получение параметров системы в статической постановке. Методологическую базу данной работы составляют нормативы и правила, а также основные результаты исследований ряда отечественных и зарубежных специалистов. Использованная в данной работе методология представляет собой сочетание методов комплексного анализа сложных статических систем. Эти методы позволяют определить для первоначального и рабочего состояний основные характеристики системы заякорения с учетом обеспечения рационального стационарного удержания объекта. Параметры систем заякорения плавучих объектов установлены с помощью расчетных методов в плоской постановке, при этом якорные связи рассмотрены как гибкие, тяжелые и нерастяжимые нити, провисающие по цепной линии. В итоге установлено, что значения статических перемещений якорных цепей зависят от угла наклона якорных связей относительно плоскости дна и величин действующих внешних нагрузок.

құралы ретінде қарастырылады. Қабілеттердің дамуы кезінде олардың даму деңгейінің
жоғарылауын түсінеміз. Жасөспірімдік шақтағы сынып оқушыларының интеллектуалдық
қабілеттерін дамытудың негізі – концептуалды ойлауын қалыптастыру. Психикалық процестер
қабілеттер арқылы жүзеге асады. Демек, қабілеттердің дамуы психикалық процестердің
қызметін жетілдірумен тығыз байланысты. Қабілеттер ерекше және жалпы болып бөлінеді.
Қабілеттердің қайсысын ерекше, қайсысын жалпы (қандай негізде қабілеттерді жалпы және
арнайы қабілеттерге жіктеу керек) деген сұрақ қазіргі қабілет психологиясында даулы
мәселе болып табылады. Көзқарастардың бірі – жалпы қабілеттер адам әрекетінің жетекші
формаларының неғұрлым жалпы жағдайларымен, ал ерекшелері – жеке әрекет түрлерімен
байланысты болады. Қабілеттерді жалпы және арнайы деп бөлу тәсілдерінің әртүрлілігіне
қарамастан, барлық психологтар жалпы қабілеттерді интеллектпен байланыстырады. Осыдан
интеллектуалдық қабілеттерді қамтитын жалпы қабілеттерді дер кезінде және барынша тиімді

As individuals age, physiologic alterations take place in the oral cavity, and are thought to be a regular component of the ageing process. However, pathological developments that are not harmless, and that need professional care, are frequently encountered. The line between physiological ageing and actual pathological changes is not clear in all cases. The wellbeing of the oral cavity can be compromised with the initiation of tooth loss, soft tissue lesions such as oral carcinoma, neglected grossly carious teeth, neglected severe periodontitis, and orofacial neuralgia. For adequate oral health to be retained in older ages, oral diseases must be prevented and/or treated with emphasis in younger ages. Proper self-management measures—like brushing of teeth with a fluoridated toothpaste, dental flossing, and consuming nutrient-dense and balanced meals which have less refined carbohydrate are crucial preventive practices to be incorporated in daily life by people of all ages which includes the elderly. Dental care professionals can play a major role in prevention of dental problems and avoidance of more damage of oral tissues in older people. Professional activities comprise head, neck, and intraoral assessment of teeth and surrounding tissues for presence of oral manifestations of systemic illnesses, oral neoplasms, carious teeth, periodontitis, and impaired function and esthetics. Other measures for prevention comprise prophylaxis, dental care guidance, fluoride varnish provision, and proper therapy via restorations and reconstructions. Since the effects of dental conditions accrue as time passes, the necessity for sooner establishment of a preventive routine in life is vital for healthy ageing intraorally. Further, dental care for the geriatric population initiates in the younger ages through a stress on management of oral health issues early on, and from that point through an elaborate preventive plan moving ahead.

Severe acute respiratory syndrome Corona virus 2 (SARS-CoV 2) was initially identified in December 2019 in Wuhan, China. The coronavirus disease (COVID-19) spread rapidly worldwide to become a global pandemic. Patients infected with this virus presented with fever, cough, shortness of breath, diarrhea, abdominal discomfort, and myalgia. Radiological examination of those patients revealed numerous findings like consolidation, ground glass opacity and can lead to lung collapse. Other uncommon features are presented such as pneumomediastinum, pneumothorax and lung cavity. Pneumothorax was one of the fatal complications mentioned in the literature as it increased the mortality of COVID-19 patients. We report four cases presented to the intensive care unit (ICU) with severe pneumonia complicated during the admission by pneumothorax, which mandated intervention by chest tube to stabilize the patient's condition. There were differences in age, sex, the treatment protocol used and the timing of the development of the pneumothorax. Pneumothorax should be kept in mind in patients admitted with pneumonia secondary to COVID-19, as it causes acute deterioration of the patient and needs urgent intervention.
Adaptation and Validation of Dynamic Career Scale (DCS) in Serbian context
Authors: Cvjetković Smiljana , Langher Viviana
Published: November 2022

Background

Dynamic Career Scale (DSC) is originally developed and validated in order to enable evaluation of implicit and less conscious dynamics in career adjustment processes. The objective of the current study was to translate, culturally adapt and psychometrically validate the DCS in Serbian population.

Methods

The instrument is theoretically grounded in psychodynamic conception of the career adjustment and measures four modes of functioning in facing career failures and challenges: true reparation, manic reparation, mania and envy. Using a cross-sectional design and multiphase sampling procedure, data were obtained from 514 respondents.

Results

Exploratory factor analysis using half of the sample supported the four-factor model with factors reflecting dimensions established in the original version of the instrument (60.29% of the variance explained). The measurement model was confirmed using confirmatory factor analysis with the other part of the sample (CFI = .930; RMSEA = .056; SRMR = .065).

Conclusion

The findings provide evidence that the four-factor structure of the DCS previously established in the Italian sample is also evident in the Serbian population, confirming the cross-cultural replicability.
Dignidad y eugenesia genética: a propósito del uso del CRISPR-Cas en embriones humanos

En el artículo se pretende abordar la discusión relativa a la dignidad y a la eugenesia genética, reflexionando si la utilización de métodos como el CRISPR-Cas en la edición genética de embriones humanos para su fecundación constituye una transgresión o una afirmación de la dignidad. Para tal propósito, se esboza un concepto de dignidad y se describe el proyecto del transhumanismo biológico, así como la edición genética en el proyecto de la eugenesia. Tras una revisión teórica y filosófica, se cuestiona la existencia de un deber de mejorar, y se argumenta la necesidad de una deliberación previa a reconocer o no un derecho a mejorar, al tratarse de una cuestión pública y no meramente privada.

The inactivation of microorganisms and autolytic enzymes by high-pressure processing results in an extension of fish muscles’ shelf life. High pressure inhibits the formation of putrefactive compounds and maintains the hardness of fish muscles, resulting in higher sensory quality compared to untreated muscle over storage time. However, the drawbacks such as discoloration, protein denaturation, and lipid oxidation could limit the application of high pressure on fish muscles. Besides, the gel formed by pressure-induction or high-pressure freezing/thawing of aquatic is being investigated intensively to obtain the benefits of high-pressure processing on aquatic products.

Antibiotic discovery was considered a wonder of the world. Shortly after, many microorganisms began to exhibit resistance to prior antimicrobial actions of antibiotics. Notwithstanding, Quinones, Flavonoids, Flavones, Flavonols, Tannins, and Coumarins are major phytochemicals synthesized by plant parts and have shown decisive antimicrobial activities against a panel of microorganisms. In this research hot and cold extracts of fresh and dried Vernonia, amygdalina showed remarkable in vivo antimicrobial activity on antibiotic-resistant Salmonella isolates from various poultry farms and food vendors in Ibi, Donga, Takum, and Wukari. 5 g-10 ml, 10 g-10 ml, 15g-10ml, 20g-10ml, and 25g-10ml are arrays of Vernonia Amygdalina concentrations tested on the inocula. Significant light growth was observed for both menstruum extracts of dried and fresh leaves of Vernonia Amygdalina at higher concentrations levels of 20g-10ml, 25g-10ml, while and moderate growth was seen at lower concentrations levels of 5g-10ml, 10g-10ml. Also, heavy growth of Salmonella was detected in the control plates inoculated with the test microorganism but without the addition of any extracts. Weak political will in implementing regulation policies, funding of research, and perceived antimicrobial resistance to plant extracts as well as acceptability and cultural factors have threatened the extensive use of plant extract in the management of health. Improved universal health coverage and enhanced economic potentials are core benefits of the use of plant extracts for health management. Conclusively, plant extracts possess appreciable antimicrobial activities against Multi-Drug Resistance (MDR) microorganisms compared to currently prescribe synthetic drugs. Hence, further studies on clinical efficacy trials and the safety of more plants need to be intensified.

The paper investigated through which subjects intercultural education can best be applied in the primary school curriculum. Teachers’ attitudes were investigated through 5 variables such as school cultural structure, gender, seniority, teacher’s prior intercultural education and teacher’s education degree. A 5 point Likert scale consisting of 6 items was used for data collection. This scale was applied to 217 primary school teachers in the Republic of North Macedonia. The ranking of subjects through which intercultural education is implemented was done through descriptive statistics. Differences in teachers’ attitudes on subject ranking were tested through t-test and One Way ANOVA. The research results showed that teachers require another form of implementation of intercultural education (M=3.55) in addition to implementation through extracurricular activities (M=3.46). Teachers working in a multicultural school think that intercultural education should be implemented through an another form, while teachers working in a monocultural school think that intercultural education should be implemented in homeroom class. Teachers with „combined“ intercultural education think that this education should be implemented through extracurricular activities, while teachers who have independently studied interculture think that intercultural education should be implemented through an another form.

The SARS-CoV-2 (COVIDs-19) pandemic made a massive impact on sudden lifestyle and food habit changes. A person's way of life, mental health, and physical health are all intertwined. Individual dietary intake and nutritional status are major elements that influence mental health. COVID-19 makes the immune system weaker than its usual times. A balanced diet is necessary to recover and to prevent the immune system for fighting against the viruses. Millions of households have experienced mobility constraints and lifestyle adjustments as a result of COVID-19 over the course of several months. The aims of the research is just to see how COVID-19 affects people's lifestyles and mental health for the change of food habits among adult population in Khulna City. Primary data was used to perform this research which was collected from adult population in Khulna City with a well-organized questionnaire. For satisfying our study purposes, some statistical methods would be applied. A significant change in mental health was found due to the impact of the situation of COVID-19 lockdown in the food habit. Female respondents (58.7%) had faced a crises on their sleep also in dietary pattern. 53.4% respondents were physically exhausted when most the respondents had a significance correlation with physical exercise with weight changes. A negative impact have been showed up in the survey as respondents were in lockdown situation which affected both financial condition and psychological environment.
‘BPRI’ (BURNT-POT ROOF INSULATION), THE NOVEL METHOD OF ROOF INSULATION IN BANGLADESH
Authors: Sarma B.B. , Darain K.M.
Published: November 2022

The roof of the building needs insulation for thermal and humidity purposes. In Bangladesh lime-terracing is used for this purpose. Mortar made of slaked lime and powdered brick (local name: surki) is applied on the reinforced roof in 100 mm layer.  It works fairly well in the situation where the variation of internal and external temperatures is low. In Bangladesh this variation in the naturally ventilated rooms is not over 3○ C and lime terracing shows a time lag of about 5 hours at this range. Some of the problems of the conventional Lime terracing are (a) It is costly, (b) It allows heat leakage when atmospheric temperature rises above 35○ Celsius and also when there is wide variation in internal and external temperatures due to air-conditioning of the room. The authors of this paper devised an alternate system. In this system air pockets were provided inside the layer such that it became lighter, consumed less material and had more insulating properties. The air pockets were provided by using burnt clay pots available in the market. The system was named Burnt-Pot Roof Insulation, abbreviated as BPRI. It was first applied in Khulna, Bangladesh in the year 2002. The cost of construction was only 10% of the cost of conventional lime terracing. The system at present is having increasing use in the country.

An investigation on floral biology of off-season jackfruit germplasms was carried out during mid July 2003 to mid November 2003 at the village Shakharipara, Rupdia, Jessore. This region is considered to be the largest jackfruit growing region of South-western region of Bangladesh. Six germplasms of more or less same aged have been selected for this study. The period for the floral bud development varied from 33 to 42 days with an average 36.8 days. Six distinct sequences of spike opening was observed on foot stalk. The availability of pollen grains and receptivity of female spike ranged from 3 to 6 days (average 4.5 days) and 8 to 12 days (average 10.26 days), respectively. Emergence of anther, stigma and dehiscence of anther occurred during day and at night. The peak emergence of anther and its dehiscence occurred during 2-4 A.M. and 4-6 P.M., respectively and the peak emergence of stigma at 8-10 A.M.
POVERTY ALLEVIATION THROUGH FISHERIES MANAGEMENT IN BANGLADESH: A RETROSPECTIVE SEARCH
Authors: Rouf M. A. , Rabbani A. G.
Published: November 2022

Development initiators in Bangladesh often focus on poverty as well as its alleviation strategies. But merely new initiatives recognize the alleviation strategies in retrospect. As a result, progress of poverty alleviation in Bangladesh is questionable. The existing and previous fisheries management strategies were reviewed with special emphasis on poverty issue. In Bangladesh, fisheries rhymes with poverty with the reflection of a complex phenomenon like low income, illness and lack of education, social exclusion, entitlement failure, vulnerability to shocks and political powerlessness. Poverty in the fisheries sector may still exist even in the situation of increase in production of fish. Moreover, disaggregating the poor into economically excluded, politically disempowered and class exploited groups reveals a range of different mechanisms working through an intra-sectoral fisheries dynamics and leading to the impoverishment of a part of the community. Strategically, Government tuned their approach from solely revenue collection with a top down approach to revenue collection with poverty alleviation approach through co-management and community based management practices. But in practice Government rarely ensures the marginal poor fishers’ involvement on the fisheries development activities that ultimately does not influence the poverty eradication level of the poor fishers. In addition to institutional legacy/complexity to disburse allocated fund in time is also an obstacle to achieve success in poverty focused fisheries development initiatives in Bangladesh.
ISOLATION AND BIOCHEMICAL CHARACTERIZATION OF BACTERIAL PATHOGEN IN COMMERCALLY IMPORTANT SHRIMP AND FISH COLLECTED FROM GHERS IN SATKHIRA DISTRICT, BANGLADESH
Authors: Reza Banu Ghausiatur , Mohashin Reza Md.
Published: November 2022

Investigations were carried out for isolation, enumeration and characterization of bacterial pathogens from shrimp Penaeus monodon and vetki Lates calcarifer from different ghers at Asasuni thana of Satkhira district. Shrimp and vetki were randomly sampled with a cast net from each gher individually during the period of September to December, 2005. After sampling, the live specimens of 20 shrimp and 12 fish were brought to the laboratory and immediately dissected. Muscle, hepatopancreas and gill were removed aseptically, weighed and homogenized with 0.85% NaCl solution. The homogenate was diluted using consecutive decimal dilution and inoculated on standard agar plates for enumeration of total bacterial load. A total load of 106-7 CFU g-1, 105-6 CFU g-1 and 107-10 CFU/g-1 were found in hepatopancreas, muscle and gill of shrimp and 105-6 CFU g-1, 106-9 CFU g-1and 107-10 CFU ml-1 in fish muscle, gill and slime, respectively. The total bacterial load in water of the ghers was estimated to be 107-10  CFU ml-1. A total of 32 and 20 representative isolates were selected from shrimp and fish respectively to identify them up to the genus through morphological, physiological and biochemical properties. Four genera namely, Vibrio, Micrococcus, Aeromonas and Pseudomonas were identified from the samples. Vibrio (56%) was predominantly isolated followed by Micrococcus (19%), Aeromonas (16%) and Pseudomonas (9%) in P. monodon whereas Pseudomonas (45%) dominated in L. calcarifer followed by Aeromonas (30%), Micrococcus (15%) and Vibrio (10%). High bacterial load in shrimp, fish and water of the ghers, it can be assumed that shrimp culture of Satkhira district is susceptible to bacterial contamination specially vibrio which is one of the devastating pathogens causing vibriosis in our country.

Acacia auriculiformis (Cunn. Ex Benth.) is now widely planted in different agroforestry models. The prime use of this species is for fuel wood and to some extent as furniture timber at the northern and central part of Bangladesh. In agroforestry, trees and agricultural crops sharing the nutrients from the same piece of land. Trees uptake nutrients from the soil and some portion of that nutrient again back to the soil through the leaching process and decomposition of litter. K and Na leaching from leaf litter of Acacia auriculiformis was studied in the laboratory. About 16% of initial dry weight of leaf litter was lost after 168 hours. Weight loss of leaf litter, conductivity and TDS (Total Dissolve Solid) of leached water showed significant (p<0.05) positive curvilinear relationship with leaching time. The initial concentration of K and Na in leaf litter significantly (p<0.05) decreased to 2247 mg g-1 and 735 mg g-1 respectively after 96 hours and showed significant (p<0.05) negative curvilinear relationship with weight loss. The pattern of K and Na leaching from the leaf litter of Acacia auriculiformis might help agroforestry practitioners to add a new criteria to choose potential tree species for their farming system.
