Disparity or continuity in the chromosome count within taxa of various categories has been verified to bean imperative character for taxonomic classification. Male meiotic studies in 64 species (161 accessions)of composits from geographically isolated regions were examined in detail in order to update the existingknowledge of meiotic chromosome numbers of composits from the outer part of the Himalayas. Myriactisjavanica (2n ¼ 36) and Tanacetum nubigenum (2n ¼ 36) have been counted chromosomally for the firsttime at the world level. Besides, Koelpinia linearis (2n ¼ 36), Ajania fruticulosa (2n ¼ 18), Crepis flexuosa(2n ¼ 14), and Tanacetum gracile (2n ¼ 18) have been analyzed chromosomally for the first time fromIndia. New intraspecific diploid/polyploid cytotypes are added for Artemisia desertorum (2n ¼ 6x ¼ 54),Carduus nutans (2n ¼ 4x ¼ 16), Erigeron annuus (2n ¼ 2x ¼ 18), Leontopodium jacotianum (2n ¼ 4x ¼ 48),Pentanema indicum (2n ¼ 6x ¼ 54), Scorzonera virgata (2n ¼ 2x ¼ 16), and Tragopogon pratensis(2n ¼ 2x ¼ 12). Besides, eight species have been evaluated cytologically for the first time from KashmirHimalayas. Various meiotic abnormalities like cytomixis, structural heterozygosity, chromatin stickiness,nonsynchronous disjunction, laggards, bridges, unoriented chromosomes leading to pollen sterility havebeen observed for the first time in some species. The presence of B-chromosomes has been detected inAchillea millefolium (2n ¼ 18þ0-1B) and Saussurea candolleana (2n ¼ 26þ0-1B). Among meioticallyanalyzed species, diploids (76.5%) and polyploids (23.5%) prevail.
Chronic Musculocutaneous Nerve Injury: An Important Differential in Progressive Arm Atrophy

An isolated musculocutaneous nerve (MCN) injury is a rare condition that can be easily missed if it presents late. A 28-year-old man reported painless and progressive wasting of the right arm for 6 months. On examination, there was visible wasting of the right biceps brachii muscle along with its slight weakness, depressed biceps jerk, and an impaired pinprick sensation in the lateral antebrachial cutaneous nerve distribution. He described a history of a road traffic accident 14 months beforehand. Based on the history and clinical examination, the differential diagnosis included an isolated MCN injury, upper trunk plexopathy, lateral cord plexopathy, C5/6 radiculopathy, and monomelic amyotrophy involving the C5/6 myotomes on the right side. The results of nerve conduction studies and electromyography were consistent with chronic proximal MCN neuropathy (right). In cases of arm wasting without pain or numbness, MCN injury should be included in the differential diagnosis, even in the presence of good power of the elbow flexors. The importance of detailed history-taking and clinical correlation cannot be over-emphasized in such cases.

AI combined with NLP techniques has promoted the use of Virtual Assistants and have made people rely on them for many diverse uses. Conversational Agents are the most promising technique that assists computer users through their operation. An important challenge in developing Conversational Agents globally is transferring the groundbreaking expertise obtained in English to other languages. AI is making it possible to transfer this learning. There is a dire need to develop systems that understand secular languages. One such difficult language is Hindi, which is the fourth most spoken language in the world. Semantic similarity is an important part of Natural Language Processing, which involves applications such as ontology learning and information extraction, for developing conversational agents. Most of the research is concentrated on English and other European languages. This paper presents a Corpus-based word semantic similarity measure for Hindi. An experiment involving the translation of the English benchmark dataset to Hindi is performed, investigating the incorporation of the corpus, with human and machine similarity ratings. A significant correlation to the human intuition and the algorithm ratings has been calculated for analyzing the accuracy of the proposed similarity measures. The method can be adapted in various applications of word semantic similarity or module for any other language.
Behaviour of high strength concrete-filled short steel tubes under sustained loading

Concrete filled steel tubes (CFSTs) are extensively used in a variety of structures due to their structural and economic advantages over other types of structures. Considerable research has been conducted with regards to their short-term behaviour, and very limited studies have focused on their long-term behaviour. In this study, a series of tests were carried out on high strength squat (short) CFSTs and concrete cylinders under controlled conditions of temperature and humidity to better understand their time dependent behaviour. A number of parameters were investigated including the influence of steel and concrete bond, confinement, level of sustained load and sizes of specimens. The results revealed that creep strains increased by more than 40% if there was no bonding between steel tube and concrete core. As expected, creep and shrinkage of concrete inside a steel tube were significantly less than those developed in exposed concrete. At the end of a creep period of six months, all the specimens were tested to failure to observe the influence of sustained loads on the ultimate strength. It was found that creep does not have a major effect on the strength of short CFSTs in the specific experimental study conducted here, which was less than 2.5%.
A Framework for Agile Development in Cloud Computing Environment
( Muhammad Younas ),( Imran Ghani ),( Dayang N. A. Jawawi ),( Muhammad Murad Khan ) 한국인터넷정보학회 2016 인터넷정보학회논문지 Vol.17 No.5
Distributed agile software development faces difficulties for instance lack of visibility across development and delivery processes, complex and disjointed development processes, inability to capitalize on business opportunities, lack of communication agility between disconnected owners, development teams, and users or clients. However these difficulties are solved with the help of cloud computing services. This study proposes a framework to provide a skeletal or structural environment for distributed agile software development in cloud computing environment. The framework guide towards the best tooling to deliver a consistent, automated, governed, and unified agile software development process with reduced technical debt, and minimized project backlog. In addition to this, the study highlights the benefits of cloud computing in agile software development.
