Objectives: This work was carried out to investigate the efficacy of galvanic vestibular stimulation in improving of gait performance and upright postural stability in hemiplegic cerebral palsy children.

Method: Thirty children were enrolled in this study and randomly assigned into two groups; group A (galvanic vestibular stimulation plus vestibular training program), and group B (vestibular training program only). Stride length and time, walking speed tests and modified Ashworth, pediatric balance scales were used to detect and follow the walking performance and upright postural stability. This measurement was taken before initial treatment and after 12 weeks of treatment. The children parents in both groups A and B were instructed to complete 3 hours of the home routine program.

Results: Data analysis was available on the 30 hemiplegic cerebral palsied children participated in the study. The difference between pre and post-treatment results was significant representative in stride length , time and walking velocity, spasticity changes and pediatric balance scores in study groups while insignificant improvement in control groups.

Conclusion: The combined vestibular training program and trans-mastoidal vestibular galvanic stimulation are suggested in improving walking performance and upright postural stability in a static and dynamic situation. So this selective physiotherapy approach may be used as a strong choice for improving walking and balance abilities in hemiplegic C.P children.

Aim: To evaluate the organoleptic, pH and pasting properties of unripe plantain (Musa paradisiaca), soybeans (Glycine max) and ginger (Zingerber officianale) as edible sources of food which can be processed into flour for several purposes.

Methodology: The plant materials (unripe plantain, soybean and ginger) used in this study were processed separately into flours. The flours were then formulated into different proportions  i.e. composite flour blends; A (100%), B(80:14:6)%, C(70:26:4)%, D (60:38:2)% and E(50:50)% and analyzed for pasting properties, pH and sensory properties using  standard procedures for 12weeks. Data generated were subjected to one-way analysis of Variance (ANOVA) in randomized block to test significant variations (P<0.05) among mean values obtained.

Results: The results showed that the peak viscosity of the blends which is the ability of starch to swell freely before their physical breakdown ranged from 651 RVU to 2766 RVU. The highest value (2766 RVU) was recorded in blend A, follow by B (1916 RVU), C (1383 RVU), D (972 RVU) while the lowest value (651 RVU) was recorded in E. The highest trough value (2462 RVU) was recorded in blend A and followed by B (1687 RVU), C (1224 RVU), D (875 RVU) and the lowest was E (550 RVU). This implies that the higher the quantity of soybean substituted, the lesser the trough. Trough which measures the ability of paste to withstand breakdown during cooling was significantly different (P<0.05) in the blends. There were significant differences (P<0.05) in the aroma of the various blends at week 0. Blend B with 6% ginger inclusion had the highest score (8.83) at 0 week, followed by blend C (8.50) with 4% ginger. Blends A and E without ginger inclusion had the lowest scores (6.25 and 6.75 respectively) at 12 weeks. The highest pH blend E (6.98) was observed at 12 weeks storage. The pH of the various blends remained acidic throughout storage of 12 weeks, an indication of shelf stability of products.

Conclusion: It was evident that supplementing unripe plantain flour adequately improved the pasting properties, pH and organoleptic properties which is a useful application in pastries like cakes and other snacks

Ensuring livelihood security of the tribal farmers of Meghalaya has been the main focus of the policymakers. To accelerate the process, it is necessary to identify the most serious issue encountered by the farmers of the region. This paper presents a list of agricultural issues associated with the livelihood security of the farmers. Using survey data from beneficiary farmers of Tribal Sub-Plan (TSP) project of College of Post Graduate Studies in Agricultural Sciences (CPGSAS), Umiam, Meghalaya and College of Home Science (CoHSc), Tura, Meghalaya, Central Agricultural University, Imphal [CAU(I)], the method of paired comparison is applied to prioritize the list of issues. The data was collected in the year 2018 from 390 beneficiary farmers from Ri-Bhoi district and West Garo Hill of Meghalaya state. The result indicates that crop diseases and pest infestation were the most critical issue. Both present and future policymaker need to intervene according to the need base situation of the farmer to ensure their livelihood security.

Groundwater is an essential resource for sustainable development all over the world. To understand the use of water resources, the fundamental characteristics and recharge of the groundwater need to be analyzed. GIS is considered as an effective and powerful tool for collecting, storing, transforming the spatial information for the need-based site-specific decision-making process. Thus, GIS tools have opened new paths in land and water resource studies. In the present study, GIS-based mapping of the groundwater in the central Brahmaputra Valley Zone is done with a view to observing the various quality characters. The results of this investigation could be used by decision-makers for the sustainable management of groundwater resources. The groundwater pH of the district was found to be within the desirable limit as recommended by WHO but 67.30% sample covering 79% of the total geographical area of the district was slightly alkaline in nature. Groundwater quality parameters that surpassed the desirable limit recommended by WHO, were electrical conductivity and nitrate which accounted for 41.22% and 0.79% of the total samples. Total Dissolved Solids, calcium, magnesium, carbonate, bicarbonate and nitrate in groundwater were recorded within the desirable limit of WHO and thus could be considered as safe. Spatial autocorrelation run for all the quality parameters with respect to their positions and values over the entire district envisaged the possibilities of forming different pattern namely CLUSTER for pH, EC, As, F, Fe, Al, Mn,HCO3, RANDOM for Mg, Ca, CO3, NO3, SO4 and DISPERSED for TDS. GIS-aided mapping of groundwater quality parameters embracing their category wise spatial distribution, area, maximum and minimum values, surface autocorrelation of observed values could give a better idea to opt for suitable need-based management strategy for the entire district.

Bioflocculants of microbial origin have the advantage of being safe, biodegradable and harmless to the environment. Production of bioflocculant by two fungi isolates and the factors affecting its production were investigated in this study. Primary screening of fungi for the production of bioflocculants, efficiencies and conditions for the optimum production of the bioflocculants were determined using standard microbiological and chemical methods. Aspergillus flavus MCB 271 and Aspergillus niger MCBF 08 were the best bioflocculant producers among the fourteen fungal isolates screened. Aspergillus flavus optimally produced bioflocculant with glucose and peptone as sole carbon and nitrogen sources respectively. Calcium ions (Ca2+) at 78.4% served as best cation sources for bioflocculant production with optimal pH of 7 and temperature of 40°C. Aspergillus niger MCBF 08 produced bioflocculant optimally when the media had peptone as a nitrogen source and maltose as a sole carbon source. The two species achieved the maximum flocculating activity of            97% (A. flavus MCBF 271) and 86% (A. niger MCBF 08) at pH values of 7 on the 3rd day of the study and caused a reduction in bacterial load of the wastewater samples by 58.73% and 60.85% respectively. These bioflocculants are thus potential replacement for synthetic flocculants conventionally used for wastewater treatment.

In branch and bound algorithm for integer linear programming the usual approach is incorporating dual simplex method to achieve feasibility for each sub-problem. Although one can also employ the phase 1 simplex method but the simplicity and easy implementation of the dual simplex method bounds the users to use it. In this paper a new technique for handling sub-problems in branch and bound method has been presented, which is an efficient alternative of dual simplex method.
