Title: Adsorptive removal of aniline from aqueous solutions by Pistacia atlantica (Baneh) shells: isotherm and kinetic studies
Abstract: Aniline is widely used as raw material in many chemical industries.This study was aimed at investigating Adsorptive removal of Aniline from aqueous solutions using Pistacia atlantica (Baneh) shells.The effect of different parameters such as pH (2- 8), contact time (10- 105min), pollutant concentration (50- 150 mg/L) and adsorbent dose (0.4- 1.5gr/L) was studied in absorption process.Qm of the baneh was 9.23 mg/L when 96% of the aniline was removed. The process of aniline absorption on P.atlantica(Baneh) shells ash was depended on Freundlich absorption isotherm more than other isotherms. Synthesis of aniline absorption on modified Baneh followed on pseudo second- ordermodel. The results showed that Baneh could consider as an effective and cheap absorber in removing the aniline from aqueous solution.

Title: Management of insect pests in tomato (Solanum lycopersicum L.) under different planting dates and mechanical support
Abstract: The experiment was conducted at the Sher-e-Bangla Agricultural University, Dhaka during the Rabi Season 2013-14 to study the effects of different planting dates and mechanical support for the management of insect pests in tomato. The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications consisted of nine treatments. Significant variations were found among the treatment. At early fruiting stage of tomato in number and weight basis, the highest percentage of infested fruit (10.65% and 10.99%) was recorded in T7 treatment, while the lowest (2.67% and 4.35%) in T5 treatment. At mid fruiting stage of tomato in number and weight basis, the highest percentage of infested fruit (11.92% and 12.62%) was recorded in T7 treatment, while the lowest (3.13% and 4.50%) in T5 treatment. At late fruiting stage of tomato in number and weight basis, the highest percentage of infested fruit (10.15% and 10.66%) was recorded in T7 treatment, whereas the lowest (2.22% and 4.21%) in T5 treatment. At total fruiting stage of tomato in number and weight basis, the highest percentage of infested fruit (10.93% and 11.43%) was recorded in T7 treatment, whereas the lowest (2.66% and 4.35%) in T5 treatment. The highest fruit yield (55.91 t ha-1) was recorded in T5, whereas the lowest yield (45.39 t ha-1) in T7 treatment. Planting at 10 December with the method of Horizontal mechanical support was more effective for reduction of insect pest of tomato and also for highest yield.

Title: Investigation of physicochemical parameter, heavy metal in Turag river water and adjacent industrial effluent in Bangladesh
Abstract: Industrial effluent (IE) is one of the major concerns in environmental issues due to its hazardous and chemical nature that is require on-site treatment and systematic management before discharge into sewage system. Therefore, the aim of this study was to investigate in order to determine the present pollution status and their alteration trends with the seasonal change of discharge amount. Water samples have been collected from Turag River adjacent to Konabari industrial area and analyzed for various water quality parameters during both dry and wet seasons. Physicochemical analyses revealed that, most of the water quality parameters exceeded the recommended levels set by the Department of Environment (DoE), Bangladesh. The dry season had significantly higher contamination loads, which were decreased during the wet season, as the river was found to be highly turbid in wet season. Furthermore, all of the dissolved metals in the water samples were also found to be significantly higher in concentrations during dry season, but still remain under the limit of recommended standards of DoE, Bangladesh, except the concentration of Cadmium in dry season. To conclude, the variation in river water flow during different seasons and the anthropogenic activities were the main reasons for this water pollution of Turag River.

Title: Analysis of classification algorithms for liver disease diagnosis
Abstract: Now a days liver disease is extending markedly due to excessive alcohol consumption, smoking, drinking arsenic contaminated water, obesity, low immunity and by inheritance. Liver cancer symptoms may include jaundice, abdominal pain, fatigue, nausea, vomiting, back pain, abdominal swelling, weight loss, general itching. Selective algorithms may be used on medical instruments (e.g. CT scanner, MRI, Ultra sono, ECG etc.) to lessen time and cost on hepatic disease diagnosis. Here some of the algorithms such as, Naive Bayes classification (NBC), Bagging, KStar, Logistic and REP tree were used to evaluate the accuracy, precision, sensitivity and specificity. For these two data sets of UCLA and AP were considered to find out the best algorithm. The whole analysis was done using the software Weka 3.6.10. It was revealed that, KStar algorithm had the maximum accuracy, precision, sensitivity and specificity. On the other, minimum accuracy was obtained from NBC. Therefore K* algorithm can be used on diagnosis tools or instruments for rapid identification of specific liver disorder.

Title: River bank erosion and its impact on population displacement in Bauphal upazila under Patuakhali district, Bangladesh
Abstract: Bangladesh is one of the most disaster prone countries around the world with severe cyclone, destructive flood and associated river bank erosion. River bank erosion is one of the major natural calamities of Bangladesh that took place in almost every year. It is a recurrent and highly unpredictable phenomenon. Two unions of Bauphal Upazila (Dhulia and Najirpur) under Patuakhali districts are also affected by river bank erosion. A field survey was carried out to assess the status of river bank erosion and population migration. Focuses of the study are to identify the nature of relationship between river bank erosion and population displacement and to evaluate the socio-economic condition of people in Bauphal Upazila under Patuakhali District. Most of the family size of the study area was medium category (50%) among the respondents (54%) were literate. Most of the respondents (80%) were involved in fishing. Majority (76%) respondents used drinking water from deep tube wells and their sanitation facility were satisfactory (68%) use kacha latrine and (24%) use semi pacca latrine. Most of the respondents (74%) were landless and average land holding of the respondents were 0.54%. Majority respondents (50%) displaced one time during their life time. Among them (65%) displaced permanently and (35%) displaced temporarily. This study describes and explains the estimation of river bank erosion in the study area and human adjustment due to the river bank erosion. Most of the people are suffering a lot of problem, i.e., people loss their homestead area and house, facing economic problems, shifting their occupation also and migrated from one place to another place. Most of the people are unable to regain their eroded land and newly developed char lands. For this hazards social instability also increase is affected area such as political instability.

Title: Influence of contamination of soil with heavy metal on the growth of three herbaceous plant species
Abstract: Contemporary literatures are awash with heavy metal contamination in soils as a source of global environmental concern. Cultivation of crops on these contaminated soils may result in accumulation of heavy metals resulting in possible risks on human health. For this reason, a pot experiment was conducted between May and August 2016 at the green house of the Department of Forestry and Environmental Management, Michael Okpara University of Agriculture, Umudike. The experiment was specifically aimed at evaluating the influence of kaoline mined soil samples on the growth of three herbaceous plant species (Chromolaena odorata, Ipomoea involucrata and Mariscus alternifolius) commonly found at abandoned kaolin mining site at Ohiya in Umuahia South East, Nigeria. The experiment was laid out in a Randomized Complete Block Design with Six (6) replicates. Data were collected on plant height, number of leaves, fresh and dry weight. Data were analyzed using Analysis of Variance (ANOVA). Mean separations were done using Fisher LSD at 0.05% probability. Two mean values were subjected to studentized-t-test using statistical analytical system (SAS) software, version 8.0. The result showed that the kaolin mined soil sample significantly affected all the growth parameters measured during the study.

Title: Advances in shampoo formulation: synergism of anionic/ cationic/ zwitterionic surfactant ternary system
Abstract: There is a rule among cosmetic formulators of not mixing an anionic surfactant with a cationic surfactant in the same formulation, especially if it’s a clear product, since this interaction will result in the appearance of turbidity (precipitation). Nevertheless, vast reports show not only the possible but also synergistic combination of surfactants with opposed charge, conferring unique properties to the final product. The aim of this study is to evaluate the use of a co-surfactant as a novel tool for maintaining high levels of both cationic and anionic surfactants mixed in the same product, without precipitation. Not only we found this possible at certain rates, but also attributes of the system such as viscosity, detergency and foam stability, were improved.

Title: Design and development of a manual potato cum sweet potato slicer
Abstract: Promotion of small scale potato processing machinery in the potato growing region would be an opportunity to reduce post-harvest loss. Making potato chips making can be a potential processing technique at house hold and cottage industry levels. In spite of a high acceptance of chips among all ages of people, the number of small scale potato processing industries in Bangladesh is not notable. One of the main reasons for such outcome is the non-availability of low cost, simple and high capacity potato processing machinery like potato slicer at local market. Therefore, a manual potato slicer was designed and fabricated in Farm Machinery and Postharvest Process Engineering (FMPE) Division of Bangladesh Agricultural Research Institute (BARI) during 2013-14. Overall dimension of the slicer was 360x390x780 mm. The slicing efficiency, throughput and non–uniform slices of the manual slicer for potato were found to be 88.80%, 59.90 kg/h and 11.22%, respectively. The capacity of the slicer for sweet potato was 42.93 kg/h. In consideration of cost, weight, ease of operation and capacity, the slicer was found suitable for cottage industry and restaurant uses.

Title: Present land size with shape and effect on the operational efficiency of rice transplanter
Abstract: Plot shape and size has great influence on the efficient operation of 4-row walking type rice transplanter. Field study was carried out in 15 villages under 15 upazila in 15 districts of two administrative divisions of Rajshahi and Rangpur to know the existing plot size, shape and length-width ratio of each plot in January-June 2017. The village in each district was selected purposively by using simple random sampling (SRS) method. The average plot number of 13 and 17 per hectare was observed in Rajshahi and Rangpur division, respectively. High degree of land fragmentation was observed in the survey areas of Rangpur division. The average plot sizes of 0.07 and 0.05 hectare were observed in Rajshahi and Rangpur division, respectively. Smaller sizes of plots (19% plots <250 m2) were dominant in Rangpur division. The plot area <250 m2 should be enlarged to get the maximum benefit of the transplanter operation. In both divisions, 5% of plot area was categorized as irregular shape where transplanter was inaccessible and initiated manual labor to transplant seedlings. The height of the rural road from the plot surface was observed more than two meter. Farmers faced problem to move the machine from road to the plot due to high elevation. Plots were observed very far from the rural road which created problem to the movement of the farm machinery. The machinery moved into the plots by crossing other plots, levees and irrigation canal. Grouping of scattered field plots or land consolidation is a complicated issue in Bangladesh. The present findings emphasized the urgency of land improvement works to improve the operational efficiency of the mechanical rice transplanter. However, the enlargement process is not an easy task. In the present context, entrepreneur should select the field based on the accessibility of farm machine, plot to plot movement time, plot elevation, plot size and shape. Careful selection of the plots will reduce the loss time during turning, plot to plot movement and consequently increase the daily area coverage.

Title: Comparative performance evaluation of DP 480 model and ARP-4UM rice transplanter
Abstract: Two types of rice transplanter model were hired to conduct the experiment at Bangladesh Agricultural University (BAU), Mymensingh in May-June, 2014 for Aman season to evaluate their comparative performances. Both the transplanters were tested in the departmental laboratory and in the field. During off-field test on concrete, the seedling per hill at high, medium and low position of seedling density controller was found 7, 5 and 4 in ARP-4UM model and it was14.3%, 20%, and 50% less in the DP 480 model compared to ARP-4UM model. During in field test the seedling per hill at high position of seedling density controller was found to be same in ARP-4UM model and DP 480 model but for medium and low position the seedling per hill was 6,3 and 1 in DP 480 model which was 25% and 50% more in ARP-4UM compared to DP 480 model. After the experiment, the transplanting depth for shallow, standard and deeper position of depth controller was found 2.39, 3.89 and 6.42 in DP 480 model and it was 10.3%, 6.9% and 30.99% less in ARP-4UM. On an average the percent of skidding was found 12.3% in DP 480 model and 16.2% in ARP-4UM model at the 15cm prefixed position of the plant to plant distance controller. Percent of missing hill in 120cm×200cm was found 4.35% in ARP-4UM model and 2.18% in DP 480 model. The field capacity was found 0.2052 ha/hr in DP 480 model and 0.1801 ha/hr in ARP-4UM model. The amount of Fuel consumed in ARP-4UM Model was obtained 1.43 lit/ha and in DP 480 Model rice transplanter it was 1.57 lit/ha. After calculating all the parameters related to the performance of the rice transplanter it was found that the DP 480 model was better compared to the ARP-4UM model in terms of break-even analysis.
