Author Co-Citation Analysis (ACA): a powerful tool for representing implicit knowledge of scholar knowledge workers
No full textIn the last decade, knowledge has emerged as one of the most important and valuable organizational assets. Gradually this importance caused to emergence of new discipline entitled ―knowledge management‖. However one of the major challenges of knowledge management is conversion implicit or tacit knowledge to explicit knowledge. Thus Making knowledge visible so that it can be better accessed, discussed, valued or generally managed is a long-standing objective in knowledge management. Accordingly in this paper author co- citation analysis (ACA) will be proposed as an efficient technique of knowledge visualization in academia (Scholar knowledge workers)
A propos des origines du « style animalier »
No full textThe Author, who is Professor of archaeology and a specialist of rock art in Central Asia examines the various theories about the origin of the scytho-siberian animal style. Prof. Sher refutes the theory of Middle Eastern origin, principally based on the discovery of the so-called « Ziwiye hoard ». Furthermore, the scientific excavation of the kurgan Arzhan (Tuva) offers strong evidence for an early datation (between 12th and 9th centuries B.C.) for the representations of the first period of this animal style, contemporary to the Karasuk culture (Late Bronze, Early Iron Age). These representations, on rock, as well as on stelae (the « deer stelae ») and artefacts, are rooted in the Early Bronze Age representations of the Okunevo and Afanasevo cultures in the Minusinsk basin and neighbouring areas. Prof. Sher traces some stylistic elements and their evolution from South Siberia towards Central Asia and further West, where they meet Middle Eastern influences.Sher Jakov A.

SEMESTER: JANUARY-JUNE'11A field experiment was conducted at the Sher-e-Bangla Agricultural University Farm,
Dhaka 1207 during the period from December 2011 to April 2012 to study the culècts of
potassium and sulphur on the growth, yield, protein and oil content of soybean (Glycine
mar var.BARI Soybean 5). The experimental soil was clay loam in texture having pH of
6.6. The experiment included four levels of potassium viz., 0, 20, 40 and 60 kg K ha" and
four levels of sulphur viz., 0, 10. 20 and 30kg S ha". The experiment was laid out in a
Randomized Complete Block Design with three replications. Potassium showed
significant effect on yield and yield attributes of soybean. Application of potassium @40
kg ha-1 produced the highest seed yield, plant height, number of primary branches plant",
number of leaves plant", number of pods plant", number of seeds plant-', 1000-seed
weight and straw yield. In all the cases lower response was found from the control
treatment. Sulphur fertilizer also had significant effect on yield and yield attributes of
soybean. Application of sulphur @ 20 kg ha" produced the highest seed yield, plant
height, number of primary branches plant', number of leaves plant", number of pods
plant", number of seeds plant'. 1000-seed weight and straw yield but in all the cases the
lower response was found from the control treatment. Potassium in combination with
sulphur showed significant effect on yield and yield attributes of soybean. The
combination of potassium and sulphur @40 Kg K and 20 kg S ha' gave the highest seed
yield, number of primary branches plant', number of leaves plant", number of pods
plant". number of seeds plant". 1000-seed weight, protein and oil contents of soybean
except plant height. The highest plant height was observed with the application of
potassium @ 60 kg ha" and sulphur @ 20 kg ha'. On the other hand, in all the cases the
lower response was found from the control treatment

ABSTRACT
The experiment was carried out in the Department of Plant Pathology of Sher-e-Bangla Agricultural University, Dhaka during the period of January, 2012 to August, 2012 to determine the prevalence of seed borne bacteria of hybrid maize variety NK-40 and their management with some selected Cu-fungicides. Three bacterial genera viz. Acidovorax sp, Burkholderia sp and Ralstonia sp were isolated from maize seeds. Moreover, three Cu-fungicides viz. Sulcox 50WP, Champion 50WP and Cupravit 50WP were used as treatments for management. Bioassay of these fungicides against different bacteria were done and observed that Sulcox 50WP @ 0.3%, Champion 50WP @ 0.4% and Cupravit 50WP @ 0.3% produced remarkable inhibition zone against Acidovorax sp, Burkholderia sp and Ralstonia sp. Effect of seed treatments were studied using nutrient agar plate method, water agar test tube method and rolled paper towel method. In nutrient agar plate method, germination varied from 94.83-98.67%, where the effect of Cu-fungicides was insignificant. In water agar test tube method, the highest number of normal seedlings (69.00%) were recorded when seeds were treated with Cupravit 50WP @ 0.3% and the lowest was recorded in control (44.67%). The lowest number of abnormal seedlings and diseased seedlings (20% and 5%, respectively) were recorded when the seeds were treated with Cupravit 50WP @ 0.3%. In rolled paper towel method, Cupravit 50WP @ 0.3% showed best performance regarding germination, shoot length, root length and vigor index. The vigor index varied from 885.50-2488.40, where the highest count was recorded in Cupravit 50WP @ 0.3% and lowest in control
Usability Evaluation of Web Office Applications in Collaborative Student Writing
No full textUsability evaluation of collaborative writing system for education usage is very essential to improve its functionality to make it effective, efficient and satisfactory for future use. In this thesis, the usability of web office (ThinkFree doc) i.e. one of collaborative tool was tested using mix research approach. Usability evaluation was done in step by step process, where usability test was conducted using think aloud protocol and observation during testing was noted down. Test results were then analyzed and questionnaire was designed for quantitative survey. Questionnaires were then distributed among those students who have been using Thinkfree doc for educational collaborative work. Interviews were conducted with all selected participants individually for results validations. During usability evaluation process positive and negative effects regarding software‟s usage were noted down. The result revealed that overall system‟s response is very slow. The software needs to improve its processing speed to make it more efficient for future use. The system also needs to improve overall functionality (e.g. collaborative work, synchronization, uploading and track changes etc) to provide accurate and complete results according users‟ requirements.First Author: M.

GENETICS AND PLANT BREEDINGThe experiment was conducted in the experimental area of Sher-e-Bangla Agricultural
University, Sher-e-Bangla Nagar, Dhaka during the time period of March to June 2022 to find
out the character association of 32 sesame genotypes. Mean performance, variability,
correlation matrix, path analysis and genetic diversity analysis on different yield contributing
characters and yield of sesame genotypes was estimated. The longest plant (127.87 cm) was
found in the genotype of G-3, whereas the shortest plant (93.29 cm) from the genotype of G-1.
The highest yield/plant (307.67 g) was found in the genotype of G-27, whereas the lowest
yield/plant (83.20 g) was observed from the genotype of G-10. Phenotypic coefficient of
variation was higher than the genotypic coefficient of variation for all the yield contributing
traits. In correlation study, significant positive association was recorded for yield/plant of
sesame genotypes with number of branches/plant (-0.049), number of capsules/plant (0.879),
length of capsule (0.355) and number of seeds/capsule (0.554). Path analysis revealed that days
to first flowering had negative direct effect (-0.326) on yield/plant. Number of capsules/plant
had positive direct effect (0.859) on yield/plant. Number of branches per plant had negative
direct effect (-0.077) on yield/plant. Number of seeds/capsule had positive direct effect (0.290)
on yield/plant. Weight of 1000 seeds had positive direct effect (0.267) on yield/plant. In genetic
diversity, cluster I was the largest cluster comprising of 20 genotypes followed by cluster II
with 9 genotypes, cluster III belongs 2 genotypes and cluster IV have 1 genotypes of sesame.
Inter cluster distance was maximum (2.761) between clusters II and III, followed by clusters II
and I (11.165). In consideration of yield contributing characters and yield G-27 perform better
followed by G-24 and G-9

BIOTECHNOLOGYThe experiment was conducted at the Biotechnology Laboratory, Department of
Biotechnology, Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during the period
of January 2021 to December 2021, to study the micro propagation of sweet potato
(Ipomoea batatas L.) in a new plant tissue culture medium (SAU tissue culture medium). Six
different culture media were compared to explore the potential of SAU Tissue cult ure
medium for regeneration of sweet potato. Data were recorded on the percentage of
regeneration, days to shoot initiation, and the number of shoots per explant at different time
intervals. The SAU tissue culture medium showed best performance for all the parameter
under study among the two other treatments MS (1962) medium and MS powder medium.
The results showed that SAU Tissue Culture Medium supplemented with 1.00 mg/L
KIN+2.00 mg/L NAA had the highest percentage of regeneration (90%), shorter days to
shoot initiation (12.33 days) as compared to other treatments. The highest number of leaves
per explant (11.33) and maximum length of shoot (9.2cm) were also observed in the same
medium at 35 DAI. In regenerated plantlets 90% survival was found in growth chamber, 85%
survival under shade house and 80% in open field condition. Micropropagation of sweet
potato was successfully done in SAU tissue culture medium which can be utilized for large
scale plantlet production program
EFFECT OF DIETARY CRUDE PROTEIN ON AMMONIA EMISSION, BLOOD PROFILE AND PRODUCTION PERFORMANCE OF BROILER
No full textDEPARTMENT OF ANIMAL NUTRITION, GENETICS AND BREEDING, SHER-E-BANGLA AGRICULTURAL UNIVERSITY, DHAKA-1207The demand for poultry meat and their products in Bangladesh has grown significantly.
Poultry sector of our country needs to increase to meet the growing domestic demand.
However, atmospheric ammonia inhibits broiler performance. Therefore, a study was
planned to investigate the effect of dietary crude protein on ammonia emission, blood profile
and production performance of broiler. A total of 135 Day-Old Lohmann broiler chicks
were reared in Sher-e-Bangla Agricultural University Poultry Farm, Dhaka-1207. Chicks
were divided randomly into 3 experimental groups of 3 replications R

, R
2
where
each replication contains 15 birds. These three treatment groups were designated as T
1
and T
3
T
2
. T
1
was high CP group containing 23% in starter phase and 22 % in grower phase.
was medium CP group (21% in starter & 20 % in grower) and T
3
was low CP group (19
% in starter & 18 % in grower). Result demonstrated that the average ammonia level in T
1
,
T
2
and T
3
were insignificant (P>0.05) at the end of 1
st
week, however it varied significantly
(P<0.05) at the end of 2
nd
, 3
rd
and 4
th
week. Here, T

showed the lowest ammonia emissions at the end of 2
nd
(3.46

and 4
th
(6.53

±0.14) week. At the end of 4
th
week significantly (P<0.05) higher emissions
of ammonia was found in T
1
(11.63
a
±0.17) and lower was found in T
3
(6.53
±0.14). BWG
(Body Weight Gain) and BW (Body Weight) at the end of 4
th
week were significant
(P<0.05) in different group. However, better BWG(g), BW(g) and FCR were found in T
1
(BWG 1885.34
a
±33.75, BW 1927.34
a
±33.75, FCR 1.35±0.02). Dressing percentage was
significantly (P<0.05) higher in T

3
(66.52
a
±0.38). The weight
of breast, wing, back and drumstick in T

and T
3
. In
case of benefit cost ratio analysis was insignificantly (P>0.05) higher in T
1
(1.35±0.02) and
T
2
(1.35±0.01) than T
3
(1.33±0.02). The immune parameter (Hemoglobin, WBC, RBC) was
significantly higher(P<0.05) in T
2
. The results of this experiment recommend that using the
low CP concentrations may reduce performance therefore may not be advisable. On the
other hand, high CP % can produce high NH
3
a
than T
1
gas production which is detrimental. It should
be keep in equilibrium state between high dietary CP supplementation and NH
3
gas
production. Indeed, as subsequent further research is needed to identify the most accurate
findings.
