Aim: The aim of this study is to assess benefit of BIM as a collaborative knowledge management tool for construction professionals.

Study Design: It was a mixed design research, the study was effected via literature review and a well-structured questionnaire. Likewise, interviews were carried out to substantiate the findings of the questionnaire survey.

Place and Duration of the Study: The study was conducted in Kaduna State, Nigeria for a period of 2 years.

Methodology: Being a mixed design research, a total of 250 questionnaires were administered and 235 were properly completed and returned representing a percentage response of 94%. Data garnered were analysed using relative importance index and presented in tables and charts.

Results: The study found that 94% of construction industry’s professionals are familiar with the concept of BIM but 94.47% of them never applied it whereas 4.68% rarely apply BIM, while 0.85 often apply BIM. Also, the research identified that all the thirteen areas where BIM can be used as a KM tool for collaboration among construction professionals were significantly important, however, Constructability Reviews and 4D Simulations which involves providing an interface to visualize the entire structure and simulate the construction process stood out as the most important.

Conclusion: The study concludes by recommending that the built environment professional bodies in Nigeria should carry out a proper sensitization programme in-order to train and retrain professionals in Nigerian construction industry as regards BIM tools and its applications. Also, BIM should be introduced as an integral part of the school curriculum for the training of future construction professionals so equipped them with the requisite BIM knowledge.

Aims: An experiment was conducted to investigate the comparative efficacy of two probiotics of different origins (yeast and bacterial based) on the growth performance and carcass characteristics of broilers chicken.

Place and Duration of Study: The study was conducted at Krishi Vigyan Kendra, Purnea between January, 2020 to March, 2020.

Methods: Two hundred and forty, day old chicks were kept and were randomly divided into 4 groups (A, B, C and D) and each group had 2 replicates of 20 chicks. Four (A, B, C and D) iso-caloric and iso-nitrogenous (ME 3000 kcal/ kg and CP 21.56%) broiler starter and finisher (ME 3000 kcal/ kg and CP 18.75%) diets were formulated containing Saccharomyces cerevisiae, Bacillus cereus toyoi and mixture of both @ 0.2% except group A which was control. Birds were raised for first week on commercial diet. Broiler starter and finisher diets were fed from 8-28 and 29-42 days, respectively.

Results: A significant (P<0.05) effect was observed on overall performance of the birds fed diet containing probiotics. Probiotics in feed at 0.2% Saccharomyces cerevisiae supplementation improved body weight gain (+12.7%), feed intake (3.8%) and feed conversion efficiency (-8.7%) compared with the control diet. Among groups, no significant differences were observed in carcass traits but highest dressing percentage was recorded in group-B followed by group-C than group-D and lowest in control group.

Conclusion: The result indicated that the addition of probiotics in feed containing 0.2% Saccharomyces cerevisiae improved broiler growth performances and it is beneficial to be used as supplement in feed of broiler chickens.

Parameter constancy is a fundamental issue for empirical models to be useful for forecasting, analyzing or testing any theory. Unlike classical regression analysis, the state space models (SSM) are time varying parameters models as they allow for known changes in the structure of the system over time and provide a flexible class of dynamic and structural time series models. The work deals with the development of state space models with weather as exogenous input for sugarcane yield prediction in Ambala and Karnal districts of Haryana. The state space models with weather as exogenous input using different types of growth trends viz., polynomial splines; PS(1), PS(2) and PS(3) have been developed however PS(2) with weather input was selected as the best suited model for this empirical study. Timely and effective pre-harvest forecast of crop yield helps in advance planning, formulation and implementation of policies related to the crop procurement, price structure, distribution and import-export decisions etc. These forecasts are also useful to farmers to decide in advance their future prospects and course of action. The sugarcane yield forecasts based on state space models with weather input showed good agreement with state Department of Agriculture and Farmers’ Welfare yield(s) by showing nearly 4 percent average absolute relative deviations in the two districts.

Ghana’s new basic school curriculum requires teachers to use new teaching strategies that also address cross cutting issues in their teaching to enhance learning. This study sought to assess the use of assessment strategies by basic school teachers in Ghana. A sample size of 100 was computed at 95% confidence interval and randomly selected from the population. The features, strategies and principles underpinning the assessment strategies and cross cutting issues in Ghana’s new curriculum for the basic school formed the basis of the construction of the 47 items used in the questionnaire. The internal consistency of the items used in the four point likert scale was high with Cronbach’s Alpha coefficient of 0.995. Principal component analysis and multiple linear regressions were the main methods used for the analysis.KMO statistic of 0.921 and Bartlett’s Test’s Chi Square value was13684.049 with difference of freedom of 1081 and significance at 0.00000. Multiple extraction approaches were used to retain two components which explained about 91% of the variance. The first component named Criterion motivation explained about 61.7% of the variance and composed generally of assessment as-of- and - for learning strategies. The second component which was named inclusion motivation, generally loaded highly with the cross cutting issues and explaining about 28.6% of the total variance. Criterion and inclusion motivation were found to predict feedback with a high power of 94%.Criterion motivation was found to have a positive impact on feedback received from students and was statistically significant (B = 0.746, P<0.001). Again, there was a positive relationship between the inclusion motivation and feedback with a significant difference (B = 0.232, P<0.001).There were some disparities in the use of assessment strategies outlined in the new basic school curriculum for Ghana. Teachers were found to exhibit preference to some components of the assessment strategies recommended for use in the new curriculum at the detriment of others. It is recommended that the developed criterion motivation and inclusive motivation approaches are adopted in teaching in order to enhance maximum feedback from learners.

The complexes of Co (II), Mn (II) and Ni (II) with Schiff base derived from pentane-2, 4-dione and 2-aminobenzoic acid were synthesized and characterized by molar conductivity, magnetic susceptibility, Infrared and elemental analyses. The solubility test on the Schiff base and its metal (II) complexes revealed their solubility in most organic solvents except chloroform and diethyl ether. The molar conductivity of the complexes was small indicating that they are non-electrolytes. The antibacterial susceptibility test conducted on the Schiff base and the metal (II) complexes showed a good activity except Ni (II) complex.

The beautiful and intricate Kashmir embroidery known as ‘Kashidakari’ is recognized everywhere for its beauty of craftsmanship, motifs, colours, textures, etc. Kashida embroidery designs are the most popular commercial embroidery designs not only because these have retained its rich heritage but also have made necessary adoption according to the likes, choice and demand of the market. In contemporary society, embroidered textiles are used for interior decoration for a traditional and royal appearance. In the present study, traditional motifs of Kashidakari embroidery were collected by exploring secondary sources for the creation of innovative designs for home furnishings textile articles. Out of 200 motifs, thirty were screened and top-ranked ten motifs were selected for design development for home furnishing, as per preferences of experts. Thirty designs were developed using selected traditional Kashidakari embroidery motifs with the help of Corel DRAW X3 software. The study concluded that all the developed designs using traditional Kashidakari embroidery motifs were highly acceptable by experts for home furnishings.
