Abstract Under the background of “carbon neutralization”, the power transmission quality of power grid transmission lines becomes more and more important. This paper discusses the mechanical properties of aluminum conductor steel reinforced(ACSR), the main medium of electric energy transmission. This test simulates the real environment, takes the stress-strain curve and elastic modulus as the starting point, divides the test process into four stages, and compares the mechanical properties of the same conductor under different loads in detail. On this basis, the data difference and performance comparison of three different sections of ACSR are obtained. Finally, the commonness and difference of different cross-section conductors are analyzed, and the precautions in the test process are given. The conclusion of this paper can promote the quality improvement of power transmission conductors.

<p>Sign languages ​​arise from the need of communities of deaf people to communicate with each other and with others. Like all natural languages, they are tied to the traditions and cultures of the communities that invented and developed them. The sign language used in Italy is the Italian Sign Language, LIS.</p> <p>The strong iconicity of LIS is very interesting from the point of view of communication and didactics of astronomy, also for the hearing impaired. The signs used for astronomical concepts and objects often express the meaning and nature of what is represented, much more than a single word in the Italian language does.</p> <p>LIS is therefore effective not only for inclusive communication aimed at deaf people, but it can be effective for everyone, both in terms of equity and awareness of diversity and in terms of knowledge of astronomy and its link with culture and tradition.</p> <p>We will present a set of videos published on EduINAF, the outreach and education online magazine of the Italian National Isntitute for Astrophysics, in which the LIS is the main medium of the storytelling. Each video has subtitles, in order to make the LIS understandable for all.</p>

Stomata are the main medium of plants for the trade of water, regulate the gas exchange, and are responsible for the process of photosynthesis and transpiration. The stomata are surrounded by guard cells, which help to control the rate of transpiration by opening and closing the stomata. The stomata states (open and close) play a significant role in describing the plant’s health. Moreover, stomata counting is important for scientists to investigate the numbers of stomata that are open and those that are closed to measure their density and distribution on the surface of leaves through different sampling techniques. Although a few techniques for stomata counting have been proposed, these approaches do not identify and classify the stomata based on their states in leaves. In this research, we have developed an automatic system for stomata state identification and counting in quinoa leaf images through the transformed learning (neural network model Single Shot Detector) approach. In leaf imprint, the state of stomata has been determined by measuring the correlation between the area of stomata and the aperture of each detected stoma in the image. The stomata states have been classified through the Support Vector Machine (SVM) algorithm. The overall identification and classification accuracy of the proposed system are 98.6% and 97%, respectively, helping researchers to obtain accurate stomatal state information for leaves in an efficient and simple way.

Malaysia whom with open arms welcomes foreigners to help develop its economy catches the attention of especially the Bangladeshis. Undoubtedly, the presence of Bangladeshis has helped in filling in the vacancies in many sectors such as plantation, construction, services and manufacturing. Their work stint and experience gained leads to a paradigm shift, from an employee to an entrepreneur. Migration to Malaysia demands them to learn and acquire the Malay language for survival. In addition, proficiency in the Malay language is an added value as it makes them feel contented, secure and successful.  This study aims to look at the perception on the proficiency of the Bangladeshis entrepreneurs who are adapting the Malay language as the main medium of communication. The relation between levels of education and proficiency in 1) speaking, 2) reading and 3) writing is analysed. This study also evaluates the importance of the Malay language usage among Bangladeshis in managing businesses. A survey was conducted on 56 Bangladeshi migrants who were involved in the business field in Kuala Lumpur. Surely, it is crucial for Bangladeshis who wish to work in this country to be proficient in the Malay language. This is to ensure their survival strategy is sustained, allowing them to tap a gold mine in Malaysian soil.

Background: The incidence of breast cancer in India is showing an increasing trend and more patients are diagnosed with breast cancer at a younger age. The prognosis of breast cancer is better when it is diagnosed at an early stage and proper treatment started early. Breast self-examination (BSE) remains as an important inexpensive tool which help in detecting any breast abnormality and diagnosing breast cancer, especially in Indian scenario. This survey was conducted among the young ladies working or studying in a tertiary care centre in Mumbai to assess the awareness about breast cancer, BSE and its practice in educated women.   Methods: This is a cross sectional study conducted among 553 females studying and working in a tertiary care institute at Mumbai. A questionnaire was prepared and response was noted down and analysed statistically.Results: According to our study even the educated women working in medical institute were not completely aware of the BSE, its practice and its importance in day-to-day life.Conclusions: The awareness  about breast cancer among students and staff  was found to be  good  in this  health care institute but most of them are not aware of proper method  and interval of BSE. The main medium of information was audiovisual. The awareness programmes need to be more for encouraging people to do a BSE and take an early medical help.

Abstract Genetics: Most Corchorus species are diploids with 2n = 14, while wild species like, C. cunninghamii, C. hirtus, C. junodii, and C. siliquosus are similar in chromosome structure and are tetraploids (Belay, 2011). C. hirtus has a chromosome number 2n=4x=28 (Sinha et al., 2011; Flora of North American Editorial Committee, 2016). Physiology and Phenology: C. hirtus flowers and fruits all year (Axelrod, 2011). The flowers are bright yellow and 1.5 cm wide, and open in the afternoon (Missouri Botanical Garden, 2016). Reproductive Biology: Most Corchorus species can be identified during the reproductive stage using capsule and seed morphology (Belay, 2011). Seed is the main medium of reproduction (Mascarenhas et al., 1995). Ideal germination conditions in the laboratory have been found to be 31°C, 12/12 meaning seeds were incubated at 31°C during 12 light hours (Royal Botanical Gardens Kew, 2008). Environmental Requirements: C. hirtus needs a tropical climate to grow but it is also present in some southern states of the USA including Arizona, Alabama and Florida. It is usually found in deciduous tropical forests, semi-deciduous and evergreen tropical forests. It prefers soils that are well drained and mostly calcareous (Mas and Lugo-Torres, 2013).

Bio-musical instruments can be defined as musical instruments made from plant wastes in the surrounding environment. One of the plant waste that is easily found in the community is coconut shell. Coconut shells are often overlooked for their use as a creative medium, especially in the field of music. Musical instruments are the main media for creativity in the art of music. The rise of musical instruments or musical instruments with high prices has become one of the inhibiting factors for young people to be creative in the field of music. Seeing this phenomenon, it is deemed necessary to develop people's creativity in making their own musical instruments at economical prices but still able to compete with manufactured musical instruments. In making this bio-instrument, the method used consists of problem identification, preparation, application, and evaluation. Through this method, the results obtained in the use of coconut shell waste into creative media are the Kalimba instrument played by plucking the iron keys as the source of the tone, while the coconut shell is used as the main medium for the sound resonance of the Kalimba instrument. Kalimba is classified into a type of lamellophone instrument, which is a musical instrument that has a tongue or a thin plate. In addition to the easy-to-use manufacturing process, the tools and materials in making these instruments are also easy to find and can even take advantage of used materials. The results of making bio-musical instruments are expected to become a reference and reference for academics and non-academics, regarding how to make musical bio-instruments using coconut shell waste.
