CIP-Bangladesh Annual Report 2009-10 compiled by Md. Mohidul Hasan. There are 5 experiments were looking at different locations of Bangladesh and presented at home and abroad by Md. Mohidul Hasan. Laght Blight, Virus, heat, salt and drought tolerance trials were conduct by Md. Mohidul Hasan Manik.
Soil is a very complex, inter-related community of microorganisms which influence physico-chemical properties and vice-versa. This study was undertaken to enumerate the culturable populations of various agriculturally important microorganisms from the soils of West Bengal. Three agro-ecological sub-regions (AESRs) were considered for this purpose, which show variation in physiography, climate and environment. The sampling of soils was done from June to July, 2015. Higher bacterial and actinomycetes populations were observed in soil samples from AESR 15.1, while in AESR 18.5 a higher fungal population was observed. This reflects the general observation that these two regions are more fertile than AESR 12.3, which is predominantly hot and dry. In AESR 12.3 and AESR 15.1, the abundance of actinomycetes in soil was found to be higher than that of fungi, indicating a significant influence of weather on the culturable microbial populations. Diversity indices were used to quantify the existing microbial diversity. It was noticed that the Ganga eastern plain showed the highest Shannon-Wiener index (0.302) of diversity while the Chhotanagpur plateau showed the lowest value (0.286). The Eastern coastal plain displayed the highest Simpson’s index of diversity (0.373) whereas the Ganga eastern plain showed the lowest value (0.350), indicating varying patterns of species richness and evenness among the three regions. The patterns of correlation between the microbes and soil properties were also noted and interpreted. This study reveals microbial diversity of soil to be a dynamic property, subject to various influencing factors.

Abstract
Potato is the second most important crop after rice in Bangladesh, where its production ranks seventh in the world. Salinity is one of the major hazards which hampers crop production in the coastal region, where levels range from 3.6 to 27.7 dS/m. Salinity levels vary with time and place and gradually increase in the dry period (December–March). A set of potato clones, bred by the International Potato Center (CIP), was evaluated for salt tolerance and productivity in replicated field trials in three coastal districts of Bangladesh. In each year of experimentation (2011–2015), salinity levels increased progressively during the season. In general they were higher at Patuakhali (0.9–18.0 dS/m) than at Satkhira (3.4–14.7 dS/m) and Chittagong (2.0–11.7 dS/m). Evaluation and selection were carried out on mean yield across the test sites, and the best performing clones were selected for the next year’s trial. Of the original 15 test clones, 2 (CIP 301029.18 and CIP 396311.1) were selected for evaluation in the regional yield trial; ‘Diamant’ and ‘Asterix’ served as checks. At the final stage of evaluation, five non-replicated field trials were conducted under farmers’ field conditions to validate the yield at farm level. Significant variation was found in yield and its components. In the regional yield trial, the highest tuber yield was found for CIP 301029.18 at Satkhira and Chittagong. At Patuakhali, the highest yield was found for CIP 396311.1. Across locations, CIP 301029.18 was the highest yielder (21.8 t/ha), followed by CIP 396311.1 (21.3 t/ha). The former produced 64% higher yield and CIP 396311.1 produced 32% higher yield compared with their corresponding check varieties. Similar ranking was found under farmers’ field conditions. After boiling, the two selected clones were found to be good in appearance and taste. and intermediate to mealy in texture. Finally, these two clones (CIP 301029.18 and CIP 396311.1) were found promising for their good productivity and quality under saline conditions, and are being considered for release as salt tolerant varieties in Bangladesh. Pot trials with saline-gradient treatments also showed that the two clones can tolerate up to 8 dS/m with respect to emergence, yield components, and proline accumulation. Our results suggest that potato could be included in cropping systems occupying suitable parts of more than 0.25 million ha of the coastal land with salinity levels up to 8.0 dS/m.

Late blight, caused by Phytophthora infestans, is the most important disease in potato production because
of its capacity to destroy foliage very rapidly and its ability to infect tubers. To avoid infection of the foliage,
fungicides are used frequently. In the Netherlands, in some years up to 15 sprays are necessary to prevent
the crop from infection by the pathogen.
Grain Yield and Some Quality Traits of Different Oat (Avena sativa L.) Genot...Agriculture Journal IJOEAR
Abstract— Oat cultivars should have both high yield potential and some quality criteria in accordance with using targets. Hence, grain yield and some quality traits of 25 oat genotypes grown in two consecutive years were studied. This study was carried out during the 2012–2013 and 2013–2014 growing seasons in Yozgat, Turkey. Grain yield, plant height, hectolitre weight, thousand grain weight, great percentage and grain composition (protein, fat, ash, acid detergent fiber (ADF), neutral detergent fiber (NDF), β-glucan and starch) were evaluated. Analysis of the combined data for two years showed significant genotypic differences for all traits. According to the average of two years, among the genotypes, grain yield varied from 2432.3 (2 numbered genotype) to 5650.2 (19 numbered genotype) kg ha-1, plant height from 76.3 to 128.3 cm, hectoliter weight from 41.5 to 52.3 kg, thousand grain weight from 24.5 to 41.3 g, groat percentage from 70.4 to 76.6 %, protein content from 11.1to 14.3 %, fat content from 5.86 to 8.47 %, ash ratio from 2.52 to 3.43 %, ADF content from 11.0 to 16.4 %, NDF content from 29.5 to 37.3 %, β-glucan content from 1.33 to 2.58 % and starch content ranged from 34.9 to 47.7 %. Grain yield was significantly and positively correlated with thousand grain weight (r = 0.253**) and neutral detergent fibre (r = 0.160**). However, correlations between grain yield with crude protein (r = -0.216**) and hectolitre weight (r = 0.246) were significantly and negative.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
