Snr.Safety Engineer Kuwait Oil Company Paper Title: “Process Safety Management (PSM) Overview and Implementation in KOC North Kuwait Fields” Description: Process Safety Management (PSM) is an effective tool to reduce operational risks in the production operation and maintenance of Facilities.Proactively identifying the hazards, assessing the risks and taking corrective action can prevent incidents/accidents.

Application

The KOC’s Process Safety Management (PSM) system and requirements are incorporated in the PSM Manual and it is applied to all KOC Directorates and their assets managed by KOC. Implementation of the PSM System is expected to enhance process safety, engineering management, reduction of major risks and process incidents, plant availability, as well as production efficiencies.The PSM Manual is also applicable to all contractors and their associated sub-contractors while designing, procuring, building, operating or maintaining KOC’s assets. Corporate HSE Group has introduced a Performance Management System to review the effectiveness of PSM system implementation based on internal & external audits of all Directorates.PSM Implementation progress and compliance with PSM Manual is assessed and measured through a set of PSM Key Performance Indicators (KPIs) Facility Integrity Management System (FIMS) & Pipeline Integrity Management System (PIMS) and these are discussed and agreed between Directorates, Corporate HSE Group and Performance Management Team. Results and conclusion All agreed set of PSM KPIs have been implenmented in North Kuwait Fields of KOC and achieved sustainable production and 20.78 Safe Million Man-hours without lost time injuries till 31.03.2014. North Kuwait Directorate was honored with many International HSE awards during the year 2013. This paper intends to present an overview of KOC PSM System and KPIs implemented in NK Fields of KOC by analyzing the process of implementation and results achieved.This paper will also share the HSE performance in terms of reduction of lagging indicators and improvement of leading indicators.

Methods other than seismic are becoming ever more actual in petroleum exploration, among them advanced electromagnetic (EM) survey. Being complementary to seismics, the advanced electromagnetic survey can identify subsurface structure and its parameters in depth range from a few meters to kilometers and reduce well placement risks by constraining reservoir locations and fluid type.

Results of EM studies can be integrated with seismic in Petrel (Schlumberger) software to obtain comprehensive view of surveyed area. Geoelectric patterns have implications for lithology, reservoir zones and their saturations, and presence of igneous rocks and faults. Either 2D or 3D resistivity data can be used at different exploration phases. With 3D data, cubes of geoelectrical and seismic attributes can be created. Transient electromagnetic method (TEM) is widely applied in Eastern Siberia (Russia) for Vendian clastic and carbonate reservoirs exploration. Derived from TEM data inversion, resistivity of sedimentary layers allows identifying reservoir properties and type of fluid saturation. Carried out EM studies in South-East Asia (Malaysia, Indonesia) show effectiveness of TEM and EM-IP techniques. The first one provides information on the sediments resistivity, structure and lithology features, reservoirs properties and fluid type. The second one investigates IP anomalies that may correlate with HC seepage zones above deposits. The role of EM methods is increasing at the areas with poor seismic data quality, non-structural fields and zones with complicated structure of sedimentary cover. Joint interpretation of EM data with seismic or other geological data is a way to reduce the exploration risks and optimize the process of geophysical investigation. Efficiency of EM exploration is shown with case studies examples. Modeling results and experience in Russia and SE Asia describe high potential of EM methods application for the Middle East region as a reliable technique in Hydrocarbon Exploration toolbox.

Authors: Chung Soon-Yeong , Lee Jae-Hwang
Published: February 2015

In this paper, we discuss the conditions under which blow-up occurs for the
solutions of reaction-diffusion equations on networks. The analysis of this
class of problems includes the existence of blow-up in finite time and the
determination of the blow-up time and the corresponding blow-up rate. In
addition, when the solution blows up, we give estimates for the blow-up time
and also provide the blow-up rate. Finally, we show some numerical
illustrations which describe the main results.
Bounds on condition number of singular matrix
Authors: Xiong Zhiping
Published: February 2015

For each vector norm ||x||v, a matrix A ? Cmxn has its operator norm ||A||?v =
maxx?O ||Ax||?/||x||v. If A is nonsingular, we can define the condition number
of A ? Cnxn as P(A) = ||A||vv ||A-1||vv. If A is singular, the condition number
of matrix A ? Cmxn may be defined as P+(A)=||A||?v ||A+||v?. Let U be the set
of the whole self-dual norms. It is shown that for a singular matrix A ?
Cmxn, there is no finite upper bound of P+(A), while ||.|| varies on U. On the
other hand, it is shown that inf ||.||? U ||A||?v ||A+||v? = ?1(A)/?r(A), where
?1(A) and ?r(A) are the largest and smallest nonzero singular values of A,
respectively.
Review of the theoretical foundation of globalization and its discontents
Authors: Dzamic Vladimir
Published: February 2015

Globalization is one of the key concepts of modern social science. Although
it almost exists for as long as human society, the scientific interest for
globalization is the largest in recent decades. Different theoretical
approaches to the phenomenon of globalization have led to different
perceptions of its character and influence on contemporary social, economic
and political phenomena, processes and relations. In this article the author
will present the most important theoretical approaches to globalization and
emphasize the theoretical controversies about globalization and its
discontents. At the same time, the author will identify the theoretical and
epistemological distinction between globalization and globalism.
Were the Sclavinias states?
Authors: Djekic Djordje
Published: February 2015

Literature has thus far denied that the Sclavinias, established in the 7th
century, were states. Various terms have been used to denominate them (e.g.
formations), but they have not been precisely defined. Considering that a
state consists of three elements: government, territory and population, this
paper shows that the Sclavinias had their rulers as early as late 4th
century, and we know them by their names in the second half of the 6th
century (Daurentius, Musokios, Ardagast and Peiragastos). Musokios is called
a rex, which a title of sovereignty. There may even have been a dynasty
(Idarisios and his sons, Mezamiros and Kelagastes). There is a record of a
term ?Ardagast?s land?, which points to a fact that the lands which Ardagast
ruled over were quite definite. The rulers exercised their authority over a
certain population which is evident from the term ?subjects? used to denote
the population subjected to Musokios. There is even an assumption that there
was the fourth element of state, a name, which constitutes a part of the
state subjects? identity. Based upon an analysis, it has been concluded that
the states were named after their rulers and not after the lands or ethnic
characteristics. Therefore, a conclusion can be drawn that the Sclavinias
were states.
Why still education?
Authors: Krstic Predrag
Published: February 2015

This paper focuses on a few simple questions that fundamentally challenge the
idea of education, as well as its modern realization. The suggestion is that,
within the undividedly accepted educational strategy of the West, there are
still uninspected costs and smuggled dilemmas. They then burden the
contemporary disputes over education at a lower level of generality: general
or vocational, culturally determined or universal, standardized or
deregulated, uniform or plural, privileged or available to all, elite or
?open? education, and so on. We believe that such thorough clearing up of
conceptual field would point to those presumed purposes, functions, and
outcomes of education which make its investments seem constantly
unsatisfactory, and education itself appears chronically in crisis.
Clinical and histopathologic features of dorsally located furunculosis in dogs following water immersion or exposure to grooming products: 22 cases (2005–2013)
Authors: Cain Christine L. , Mauldin Elizabeth A.
Published: February 2015

Objective—To describe clinical and histopathologic features of furunculosis in dogs following water immersion or exposure to grooming products.

Design—Retrospective case series.

Animals—22 dogs with skin lesions consistent with furunculosis and a history of water immersion or grooming prior to onset.

Procedures—Information collected from the medical records of affected dogs included signalment, clinical signs, bathing or grooming procedure, diagnostic tests, treatment, and outcome.

Results—German Shepherd Dogs (4/22 [18%]) and Labrador Retrievers (4/22 [18%]) were most commonly affected. Skin lesions, particularly hemorrhagic pustules and crusts, were dorsally located in all dogs and occurred a median of 2 days (range, 1 to 7 days) following water immersion or exposure to grooming products. Twenty (91%) dogs were bathed at home or at a commercial grooming facility prior to lesion onset; 1 dog developed skin lesions following hydrotherapy on an underwater treadmill, and 1 dog developed peri-incisional skin lesions after surgery. Lethargy, signs of neck or back pain, and fever were common clinical signs. Pseudomonas aeruginosa was the most common bacterial isolate from dogs with bacteriologic culture performed on skin samples (10/14). The main histologic feature was acute follicular rupture in the superficial dermis with suppurative inflammation and dermal hemorrhage. Systemic antimicrobial treatment, particularly oral administration of fluoroquinolones, resulted in excellent clinical response in 16 of 22 (73%) dogs.

Conclusions and Clinical Relevance—Acute-onset furunculosis with characteristic clinical and histopathologic features in dogs following water immersion or exposure to grooming products was described. Knowledge of the historical and clinical features of this syndrome is essential for accurate diagnosis and appropriate treatment of affected dogs.
Multiple magnetic gastrointestinal foreign bodies in a dog
Authors: Garneau Mark S. , McCarthy Robert J.
Published: February 2015

Case Description—A 3-year-old castrated male Yorkshire Terrier was referred because of a 3-day history of vomiting, hyporexia, and lethargy after suspected ingestion of magnetic desk toys. Multiple metallic gastric foreign bodies were visible on radiographic views obtained 24 hours previously by the referring veterinarian.

Clinical Findings—On physical examination of the dog, findings included moderate dyspnea, signs of pain in the cranial portion of the abdomen, hypothermia, and tachycardia. Repeated radiography revealed moderate pleural effusion and the presence of several round metallic foreign bodies in a linear ring formation in the distal aspect of the esophagus and gastric cardia.

Treatment and Outcome—Endoscopy was performed, at which time the dog became increasingly dyspneic, tachycardic, and hypotensive. Thoracocentesis was performed, and a large volume of septic exudate was removed from the left hemithorax. Exploratory surgery of the thoracic and abdominal cavities was performed, during which the magnetic foreign bodies were removed and esophageal and gastric perforations were debrided and closed. The dog died following acute cardiac arrest 48 hours after surgery.

Clinical Relevance—Ingestion of multiple magnetic foreign bodies carries a high risk of gastrointestinal tract perforation, volvulus, and obstruction. Immediate surgical intervention is recommended in such cases and would have likely improved the outcome for the dog of this report.

Published: February 2015

Twenty two genotypes of cucumber (Cucumis sativus L.) were evaluated using D2 and principal component analysis (PCA). The genotypes were collected from Plant Genetic Resources Centre (PGRC) of Bangladesh Agricultural Research Institute (BARI), Gazipur , Agro-G, & Lal Teer seed company. The study was undertaken at Sher-e-Bangla Agricultural University Farm, Dhaka during March 2010 to October 2010 to select suitable donor parents for improved breeding of cucumber. Principal component analysis (PCA) revealed that the first two axes accounted for 67.39% of the total variation among the fourteen characters studied. As per cluster analysis, the genotypes were grouped into four clusters consisting 5, 3, 8 and 6 genotypes which revealed that there exist considerable diversity among the genotypes. Highest intra-cluster distance was found in cluster ?I and lowest in cluster ?V. Among four clusters, the highest inter-cluster distance was observed between cluster ?I and cluster ? and lowest between cluster I and cluster ?V. Considering all of the characters studied, the Serena, BD-4305, BD-4256, CU937F1 and BD-4309 were selected for future breeding programme.DOI: http://dx.doi.org/10.3329/jesnr.v6i1.22036 J. Environ.

Authors: Rahman MM , Afroz MS , Ferdoush JN
Published: February 2015

The effect of municipal solid waste compost, fertilizers, Rhizobium and flora on the growth and yield of wheat was studied through a field experiment at the Soil Science Field Laboratory of Bangladesh Agricultural University, Mymensingh. The soil was silty loam in texture having pH 6.94, organic matter 1.62%, total nitrogen 0.067%, available phosphorus 10.45 ppm, exchangeable K 0.08 me/100g soil, available sulphur 12.00 ppm and cation exchange capacity 15.0 me/100g soil. There were seven treatments such as T0 = control, T1 = 100% recommended doses of fertilizer (RDF), T2 = 100% RDF + compost @ 3.5 t ha-1, T3 = 100% RDF + compost @ 3.5 t ha-1 + Rhizobium, T4 = 75% RDF + 25% N based compost, T5 = 75% RDF + 25% N based compost + Rhizobium, T6 = 100% RDF + Flora. The experiment was laid out in a Randomized Complete Block Design with three replications. Phosphorus, potassium, sulphur, zinc and boron were applied as basal dose from TSP, MOP, gypsum, zinc sulphate and boric acid @ 30 kg P, 135 kg K, 15 kg S, 2 kg Zn and 1 kg B, respectively. Nitrogen as urea was used @100 kg ha-1 for the respective treatments. For T3 and T5, the seeds were inoculated with Rhizobial strains. The plants were harvested at maturity and the grain and straw yields were recorded. Wheat grain and straw samples were collected and analyzed for N,P,K and S. The nutrient uptake of wheat calculated. Application of municipal solid waste compost, fertilizers, Rhizobium and flora increased the N and S content both in grain and straw of wheat but decreased the P content as compared to control. The K content in wheat straw increased with different treatments but the effect was reverse in case of wheat grain. The N,P,K,and S uptake of wheat grain and straw as well as the total uptake increased significantly with all the treatments over control.DOI: http://dx.doi.org/10.3329/jesnr.v6i1.22039 J. Environ.

Authors: Islam MK
Published: February 2015

Efficacy of storage treatments, namely control, paraffin coating, perforated polyethylene cover, unperforated polyethylene cover, hot water (55±1 0C) and low temperature (4±1 0C) on behavioral pattern of mineral constituents and storability of the two postharvest mango genotypes (viz., Langra and Khirshapat) was examined in the sophisticated laboratory of SRDI, Rajshahi, Bangladesh during the period from June, 2011 to September, 2012. The results of the investigation obtained from genotypes appeared predominant variation in terms of most of the characters studied in the laboratory situation. The Langra enriched a greater amount of P, Mg, Fe and Mn over the Khirshapat and the process of enrichment was gradually increased with the advance of storage period up to the last edible stage. The Khirshapat showed a greater performance in producing of Ca, Cu and Zn, and longer shelf life in comparison with the Langra at all the storage times. The mineral constituents of mango pulp were also changed during storage period. Low temperature (4±1 0C) was found to be more effective in retaining the original green color of mangos for a period of time, but it caused chilling injury and fruits did not ripen at all after removal from low temperature. Paraffin coating was assumed to be better in retarding the ripening process of the postharvest mango, which might be easily adopted by common people for the mango storage.DOI: http://dx.doi.org/10.3329/jesnr.v6i1.22043 J.

Data were collected randomly from selected 52 broiler farmers through personal interview using an interview schedule. The highest number of broiler farmers 69.2% and 57.7% in Jessore and Bhola District, respectively belonged to middle aged group (31-50 years) involved in broiler farming. About 48.1% and 59.6% broiler fermers respondents of Jessore and Bhola District, respectively possessed secondary level of education involved in broiler farming. About 48.08% and 63.46% broiler farmers in Jessore and Bhola District, respectively disinfected their farm using lime water. About 40.38% broiler fermers administered vaccine against ranikhet, gumboro, infectious bronchitis diseases and 36.64% administered vaccine against ranikhet and gumboro diseases in Jessore and Bhola District, respectively. About 36.54% broiler fermers applied antibiotic against coccidiosis, dermatitis and respiratory infection diseases and 44.23% broiler fermers applied antibiotic against coccidiosis, dermatitis and respiratory infection diseases in Jessore and Bhola District, respectively. The highest number of broiler farmers in Jessore District faced great marketing problems due to unfavorable market for selling broiler, high price of feed and chick and in Bhola District the farmers faced great marketing problem due to the unstable and high price of feed and chicks.DOI: http://dx.doi.org/10.3329/jesnr.v6i1.22046 J.

Authors: Alam F , Hashem MA , Rahman MM , Rahman SEM , Hossain MM , Rahman Z
Published: February 2015

The experiment was carried out to examine the possibilities of making compost by using layer litter with different bulking materials and to assess the nutritive value of compost. To fulfill the objectives five treatments were considered e.g., anaerobic composting with layer litter (T1), layer litter with straw (T2), layer litter with tree leaves (T3), layer litter with crop residues (T4) and layer litter with saw dust (T5) under soil surface. The samples from composted materials were collected at 0, 10, 20 and 30 days for proximate analysis. At 0 day of layer litter composting DM content did not vary significantly (p>0.01) var ied in all treatments.. At 10 day of layer litter composting DM content was the highest in T4 (50.0%) and CF content was the highest in T2 (22.2%). CP content remained similar varied in all treatments. At 20 day of layer litter composting DM content was highest in T4 (51.5%), CP content was the highest in T4 (19.5%), CF content was the highest in T2 (18.0%), Ash content was the highest in T4 (18.5%). At 30 day of layer litter composting DM content was the highest in T2 (51.1%) and CP content was the highest in T4 (17.6%). The pH value decreased upto first tendays then gradually increased with the composting period and highest value was obtained by T1 (8.40) then followed by T2 (8.20), T3 (8.15), T5 (8.10) and T4 (8.00) (p<0.01) at 30 d of composting. The C/N ratios increased (p<0.01) in all treatments with the advancing of composting period and highest value was obtained in T4 (27.9) followed by T1 (26.7), T5 (26.3), T3 (26.2) and T2 (25.3) considerably with the composting period. So, it may be concluded that proximate composition of all samples at 20 days in T4 treatment was acceptable up to the end of composting period. However, composting layerlitter with crop residues (T4) was more effective compare to other treatments at 20 days of composting in terms of Dry matter, CP content, C/N ration and pH.DOI: http://dx.doi.org/10.3329/jesnr.v6i1.22054 J.

The maximum and minimum values of lE/Rn (latent heat fluxes/Net radiation) ratio in Aman rice field were 0.63 MJm2, and 0.16 MJm-2, respectively whereas the average value was 0.41 MJm-2 during wet condition. H (Sensible heat fluxes) was positive during the day with few fluctuations and the ratios of H/Rn fluctuated from 0.67 MJm-2 to 0.22 MJm-2 while the average value was 0.45 MJm-2 and this phenomenon was due to available moisture availability in the Aman rice field. The maximum G/Rn ratio was 0.20 MJm-2 while the minimum ratio was 0.09 MJm-2 and their average value was 0.14 MJm-2. The value of G was considerably small due to the canopy architecture in Aman rice cropping system. In post Aman rice field, sensible heat flux density of the fallow rice field showed highest 25.66 MJm-2. On an average, H was 58.6 % of the whole Rn while the minimum and maximum portions were5.68 % and maximum of 114.86 %, respectively in well irrigated fields. The measured average H/Rn ratio was 0.54 MJm-2 in post Aman rice field while their maximum and minimum values were 0.79 MJm-2, 0.07 MJm-2, respectively. The lE/Rn ratios ranged from 0.05 MJm-2 to 0.76 MJm-2 with an average value of 0.30 MJm-2. G/Rn accounted maximum 0.24 MJm-2, minimum 0.07 MJm-2 and on an average 0.16 MJm-2 and G was considerably larger than vegetative fields due to the less crop canopy architecture in post Aman rice fallow field. In Boro rice field variations in Rs mainly observed due to weather condition. H/Rn ratios from the rice field and observed that the maximum 0.88 MJm-2, minimum 0.20 MJm-2 and on an average 0.49 MJm-2, this phenomenon due to seasonal weather characteristics. The lE/Rn ratios in the Boro rice field observed maximum 0.60 MJm-2, minimum 0.04 MJm-2 and on an average 0.35 MJm-2. G accounted maximum 0.22 MJm-2, minimum 0.08 MJm-2 and on an average 0.16 MJm-2 and G was considerably small due to the canopy architecture Boro rice cropping system. In post Boro fallow rice field the maximum value of the ratio of lE/Rn was 0.82 MJm-2 while the minimum value was 0.41 MJm-2 with an average of 0.66 MJm-2. The lE/Rn ratios exhibited the highest ratios among the all observation periods and due to more availability of water. The H/Rn ratios observed maximum 0.50 MJm-2, minimum 0.12 MJm-2 and on an average 0.25 MJm-2. G accounted maximum 0.14MJm-2, minimum 0.06 MJm-2 and on an average 0.09 MJm-2 and G was considerably smaller than vegetative fields due to the less crop canopy architecture and much water availability in post Boro rice fallow field.DOI: http://dx.doi.org/10.3329/jesnr.v6i1.22065 J.

Eight F2 populations generated through inter-varietal crosses, along with three check varieties of Brassica rapa were evaluated to study the variation in different characters, correlation between pairs of different characters and the direct and indirect effect of different characters on seed yield per plant to select the plants with higher yield potential. From the values of mean, range and (CV%) of seed yield and yield contributing characters it was confirmed that there were considerable variation present among all the genotypes used in the experiment. The values of phenotypic variances were higher than the cor responding genotypic variances. Number of branches per plant, length of siliqua, seeds per siliqua, 1000 seed weight and yield per plant showed least difference between phenotypic and genotypic variances. The values of GCV and PCV indicated that there was least variation present among most of the characters studied. The number of branches per plant, days to 50% flowering, days to maturity and length of siliqua had showed high heritability with low genetic advance and genetic advance in percentage of mean. Yield per plant had significant and highest positive correlation with plant height, days to 50% maturity, length of siliqua and seeds per siliqua. The path co-efficient analysis revealed that siliqua per plant had the highest positive direct effect followed by seeds per siliqua, length of siliqua and plant height. Sixteen most promising plants with higher yield were selected for cultivation.DOI: http://dx.doi.org/10.3329/jesnr.v6i1.22068 J. Environ. Sci. & Natural Resources, 6(1): 217-220 2013

Authors: Kabir MH , Ismail M , Jashimuddin M
Published: February 2015

The study was conducted to analyze the solid waste recycling at Sholokbahar Ward of Chittagong City Corporation. Data were collected from primary waste collectors, i.e.Tokai, Feriwala, and Women waste collectors, waste dealers and different recycling plants through questionnaire survey and frequent field visits. The study found that the average amount of collected recyclable solid wastes was 121.37 kg/day in each solid waste recycling shop while waste picker was about 16 kg/day. Interestingly, the amount of average collected solid waste per day by Feriwala was significantly higher than Tokai and women waste pickers. Among of recyclable solid waste about 37% was scrap iron while only 16% was plastic bottle. The study also found that solid waste pickers generally collect wastes on foot while, among Feriwala only 23% use tricycle to collect wastes from door to door. We estimated that, by collecting recyclable solid wastes, each male and female waste picker earn, on an average, Tk. 80 and Tk.53 per day respectively. Finally, this study suggests that both governmental and non-governmental initiatives for solid waste recycling at Sholokbahar area can play a vital role to contribute our national economy, employment opportunities and environmental protection.DOI: http://dx.doi.org/10.3329/jesnr.v6i2.22078 J.

Published: February 2015

SIDR had great impact on crop, livestock and fisheries at Pirojpur district in Barisal Division. To perform this study data were collected from the three selected village (south Shailkati, Hothkhali and Lahori) affected people by random sampling after selecting the study topic and area. SIDR also created a great impact on the production of different types of crop. Rice production was reduced to 7.5%, chili to 11.66% and vegetables to 10%. After SIDR the production of pulse was increased 21.67% due to increase in acreage in Pirojpur. From this study we found vegetables lands (58.33%) and fish in river (70.83%) were affected by the saline water than the rice (33.33%), fruit (9.16%) and fish in pond (24.16%) respectively. Due to the tidal surge and storm the cattle reduced to 18%, goats to 14%, buffalos to 21%, chickens to 10.09%, duck to 8.82%, Pigeons to 24%; that means majority of the poultry birds were reduced than the livestock. The food habit of the affected people was also changed. They now took more flour rather than rice. The scarcity of agricultural production created the reduction of food stock. Most of the respondents had no food stock. But the situation is better than close post SIDR period. Most of the cases they are adopting with the changing socio-economic conditions.DOI: http://dx.doi.org/10.3329/jesnr.v6i2.22084 J. Environ. Sci. & Natural Resources, 6(2): 25-30 2013

A survey was conducted to get an overview and to gather information on the existing and socioeconomic condition of the SIDR affected people and migration. To perform this study data were collected from the three selected village (south Shailkati, Hothkhali and Lahori) affected people by random sampling after selecting the study topic and area. Then the data were processed and analyzed through using different statistical tools like pie-chart, bar diagram, table etc. The GoB and NGOs subsidiaries, also help the SIDR victims to cope with the situation. From the study we found that the NGOs contributed more to adapt with the situation. After SIDR the occupation of non-agriculture day-labour increased (37%) and the occupation of agriculture decreased 31% from 55.64%. After SIDR middle income group people were greatly affected. The income and expenditure of middle income group people were found to reduce. Low income group people increased their income and expenditure was decreased. After SIDR due to decrease their average income, they could not manage their basic needs. The food habit of the affected people was also changed. They took more flour rather than rice. The scarcity of agricultural production created the reduction of food stock. Most of the respondents had no food stock. The rate of internal migration was also increased. The rate of migration to other places (47%) and Dhaka (53%) was increased due to SIDR. But the situation was better than close post SIDR period. Most of the cases they are adopting with the changing socio-economic conditions.DOI: http://dx.doi.org/10.3329/jesnr.v6i2.22094 J. Environ. Sci. & Natural Resources, 6(2): 43-47 2013

Published: February 2015

The experiment was conducted in medium highland at Dacope, Khulna during rabi season of 2010-11. The aim of the study was to observe the effect of integrated use of bio-slurry along with inorganic fertilizer on the performance of water melon grown in AEZ 13. The experiment was laid out in a randomized complete block design with four replications. Three fertilizer doses viz. T1 : Soil test based inorganic fertilizer dose for high yield goal (HYG), T2 : Cowdung bio-slurry @ 5t/ha + IPNS basis inorganic fertilizer dose for high yield goal and T3 : Farmers practice (average of 20 farmers surveyed) were taken as treatment. Results showed that yield and yield contributing characters of water melon were significantly influenced by the treatments. The highest fruit yield (44.50 t/ha) was recorded in cowdung bio-slurry@ 5 t/ha + IPNS basis inorganic fertilizer dose (T2) followed by T1 (40.27 t/ha). The lowest yield (35.20 t/ha) was obtained from farmers practice. Economic analysis also revealed that the gross return (Tk. 534000.00/ha) and gross margin (Tk. 427515.00/ha) were higher in T2. Benefit-cost ratio (BCR) was also higher in T2 (5.01).DOI: http://dx.doi.org/10.3329/jesnr.v6i2.22097 J. Environ. Sci. & Natural Resources, 6(2): 61-63 2013

Authors: Rahman MS , Abedin MZ , Rana MM
Published: February 2015

The present study was undertaken to monitor the seasonal variations in wastewater quality of Mymensingh municipality area discharged into different locations at the Brahmaputra River. Five sample collection points were purposively selected from five different discharge locations of the study area. The samples were collected during January to November 2012. Collected samples were analyzed for pH, Electrical Conductivity (EC), Total Dissolved Solids (TDS), Dissolved Oxygen (DO), Total Nitrogen and Available Phosphorus. The study results revealed that the value of EC, TDS, DO, Total Nitrogen and Available Phosphorus of the wastewater samples varied with seasons. The pH was consistently same through out the year, EC, TDS, Total Nitrogen and Available Phosphorus were relatively low in rainy season and high in winter, but DO was high in rainy season and low in winter. Considering the investigated parameters, the wastewater of Mymensingh municipality area that discharged into the Brahmaputra River was suitable for rice irrigation. For aquacultural purposes most of the discharge points of wastewater were not suitable except in rainy season, because the majority part of the year Dissolved Oxygen level was very low that may results in fish mortality. The wastewater containing excess phosphorus and nitrogen may cause algae growth in quantities sufficient to create bad odor. Dead and decaying of algae may also cause oxygen depletion which can kill fish and other aquatic organisms in the Brahmaputra River in winter season.DOI: http://dx.doi.org/10.3329/jesnr.v6i2.22098 J.

Published: February 2015

Temperature is one of the pivotal climatic variables in our world climate literature. In the present study monthly, seasonal and yearly highest maximum and lowest minimum temperatures of two cities were analyzed. Mann-Kendall test and Sens Slope Estimator were used to determine the trend and slope magnitude. Chittagong, as the coastal city and Rajshahi, as Barind track were selected as a study area due to its respective geographical location. Such types of data of 52 years for Chittagong as well as 48 years for Rajshahi were collected from Bangladesh Meteorological Department (BMD). Monthly highest maximum and lowest minimum temperature data from 1950-2002 for Chittagong and 1964-2012 for Rajshahi were used for analysis. In Rajshahi, significant rising trends were found in highest maximum post-monsoon temperature, lowest minimum monsoon temperature and highest maximum temperature from July to October, June and August for lowest minimum temperature. Falling trends were found in annual highest maximum and lowest minimum temperatures, pre-monsoon highest maximum temperature, lowest minimum winter temperature and January lowest minimum temperature. For Chittagong, significant increasing trends found in post-monsoon highest maximum temperature, June to December highest maximum temperature except July and December lowest minimum temperature. No significant decreasing trend was found in Chittagong.DOI: http://dx.doi.org/10.3329/jesnr.v6i2.22101 J. Environ. Sci. & Natural Resources, 6(2): 83-88 2013

Published: February 2015

The study was undertaken to determine the livelihood status of slum dwellers in some selected areas of North Dhaka City Corporation and to explore the relationship between livelihood statuses of slum dwellers with the selected characteristics. Data were collected from 130 slum households by using interview schedule from July to October 2012 in following a stratified random sampling procedure. Majority (43.08%) of the respondents were young in the study area. Almost one half (43.07%) of the respondents was illiterate to could sign only. Majority of the slum people were found in the low annual income category, low media contact, low training exposure and medium environmental knowledge. Overall livelihood status of the slum people was found low and majorities (65.37%) of the respondents were found having high problems (such as lack of proper waste management system, lack of proper sanitation and drainage system, water crisis than necessary and lack of proper health facilities). Relationship among the variables was determined by using the Pearsons Product Moment correlation co-efficient (r). The computed value of correlation coefficient showed that education, annual income, media contact, training exposure, and knowledge about environment showed significant positive relationship at 0.01 level of probability with their livelihood status. On the other hand, age, family size and credit had no significant relationship with their livelihood status.DOI: http://dx.doi.org/10.3329/jesnr.v6i2.22102 J. Environ.

The experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh, Bangladesh to investigate the effect of age of tiller seedlings, number of tiller seedlings hill-1 and application of urea super granules (USG) on the growth parameters of transplant aman rice cv. BRRI dhan52. The experiment comprised two ages of tiller seedlings viz. 25 and 35 days old, three levels of tiller seedling hill-1 viz.1, 3 and 5 seedlings hill-1 and three USG levels viz. 0, 1.8 and 2.7g USG. The experiment was laid out in a Randomized Complete Block Design with three replications. The highest and lowest plant height was found by transplanting 25-day and 35-day old tiller seedlings at all dates of observations. By transplanting 35-day old tiller seedlings total dry matter hill-1 was found highest at 15DAT and 45 DAT. Total dry matter hill-1 was the highest in 5 tiller seedlings hill-1 and it was in lowest in 1 tiller seedling hill-1. Plant height was the highest in 5 tiller seedlings hill-1 which was as good as that of 3 tiller seedlings hill-1 and the lowest one was found in 1 tiller seedling hill-1 at 15 DAT. The tallest plant and highest total dry matter hill-1 were observed in 1.8g USG and the lowest one was observed in control treatment. Transplant Aman rice can be grown by transplanting 25-day old tiller seedling, 5 tiller seedlings hill-1 and by applying 1.8g USG for the highest plant height, more tiller and total dry matter production hill-1.DOI: http://dx.doi.org/10.3329/jesnr.v6i2.22104 J.

Causes of Deforestation and Conservation of Madhupur Sal Forest in Tangail Region
Authors: Hossain MN , Rokanuzzaman M , Rahman MA , Bodiuzzaman M , Miah MA
Published: February 2015

Over the past few decades deforestation has become the issue of global concern for its rapid reduction of biodiversity. The tropical moist deciduous Sal forest ecosystem of central Bangladesh is currently in a critical situation. Destructive anthropogenic and natural impacts coupled with overexploitation of forest resources have caused severe damage to the forest ecosystem. Due to rubber monoculture, expanding commercial fuel wood plantations & expanding agriculture, illegal cutting, encroachment of forest areas, and illegal poaching of wildlife, the Sal forest is losing biodiversity alarmingly. The study is based on intensive literature survey and tries to explore the overall deforestation situation and conservation practices for Madhupur Sal forest that comprises about 5% of the total forests in Bangladesh. The level of destruction of the natural Sal forest has pushed the forest-dwelling indigenous Garo community into cash crop production, forcing them to move away from their traditional subsistence economy. Now we need to address a joint conservation and improved management plan of the forest resources use. Thus all kinds of military establishments, construction of roads and highways for military purposes should be avoided and a policy of planned industrialization should be adopted to mitigate the adverse effect of industrialization. Findings of the study will help to identify the causes of deforestation and conservation of Madhupur Sal forest and also in other national parks in Bangladesh which ultimately conserve the biodiversity and help to maintain natural balance.DOI: http://dx.doi.org/10.3329/jesnr.v6i2.22105 J.

Time Series Properties of Some Climatic Variables in Dinajpur District
Authors: Rahman MJ , Syeda JA , Nasser M
Published: February 2015

Several direct empirical time series investigations of global climate change and its impact have been studied by several world famous researchers. Some researches regarding local climatic change and its impact have been published but the time series properties of the variables related to national as well as local climate are yet to be able to have proper attention. The presence or absence of unit roots in these time series or inappropriate statistical tools may challenge the validity of the interpretations of their results and implies that cointegration analysis can be used to investigate the relation among variables. This article attempts to deduce time series properties of temperature, rainfall and humidity of Dinajpur district.DOI: http://dx.doi.org/10.3329/jesnr.v6i2.22109 J. Environ.

Authors: Hossain SAA Mamun , Adham AKM , Uddin MJ
Published: February 2015

The focus of this study is to observe the influence of barb on channel bed configuration by using iRIC-Nays2D, a multi-dimensional computational model for river flow and riverbed variation analysis solver package. The two-dimensional (2D) numerical simulation is represent the effects the pre-existing condition (i.e. before construction of barb) and in the presence of the barb installed on sidewall of the channel. The average flow depth, and discharge were used as 0.044 m and 0.028 m3/s, respectively. The numerical simulation reproduced the features of barb with time at upward side and creates scour holes at the leeward side of the structure. The simulation results confirmed that the vicinity of the barb head achieved a substantial reduction in scour, increase stream-wise velocity and sediment deposition at near bank. Bars were formed along the bank-line at the upstream portion of the structures. On the other hand, at the downstream side near the barb head scour occurs due to hydraulic jump and turbulence flow mixing.DOI: http://dx.doi.org/10.3329/jesnr.v6i2.22110 J. Environ.

‘Otherwise in London’ or, the ‘Essence of Things’: Modernity and Estrangement in the Nineteenth-Century Cityscape
Authors: Wolfreys Julian
Published: February 2015

Writers of the early nineteenth century sought to find new ways of writing about the urban landscape when first confronted with the phenomena of London. The very nature of London's rapid growth, its unprecedented scale, and its mere difference from any other urban centre throughout the world marked it out as demanding a different register in prose and poetry. The condition of writing the city, of inventing a new writing for a new experience is explored by familiar texts of urban representation such as by Thomas De Quincey and William Wordsworth, as well as through less widely read authors such as Sarah Green, Pierce Egan, and Robert Southey, particularly his fictional Letters from England.
