Multiple Attributed Parametric Review Study on Mechanical Cotton (Gossypium hirsutum L.) Harvesters

Crop characteristics of cotton are crucial to identify the important crop attributes like plant height, canopy width, sympods and monopods distribution, row spacing which affects the performance of mechanical harvesters. The activity and effectiveness of most harvest aids, including desiccants is reduced by low temperature conditions. Trash content was observed to be lesser in cotton harvested by cotton picker than cotton harvested by cotton stripper. It was found that a maximum cotton yield of 1000 kg acre-1 was obtained for a cotton plant population ranging between 45,000 and 90,000 plants acre-1. Likewise, a minimum of 700 to 740 kg acre-1 was observed for a cotton plant population of 33,000 plants acre-1. In higher yielding cotton, cotton pickers recorded higher picking rate than cotton strippers. Picking/harvesting efficiency of cotton stripper with both finger and brush type mechanism was higher than the spindle type cotton picker. Picking efficiency of pneumatic picker was higher than the other types of picking mechanisms, but with lesser rate of picking capacity. Gin turnout of cotton was higher with cotton picker when compared with cotton stripper due to lesser trash content in picker harvested cotton. The horsepower requirement of cotton stripper ranged from ½ to ¼ horsepower and cost is about two-thirds of the price as compared with cotton picker. The scheduling and monitoring of various activities involved in cotton picking by using a suitable software model can increase the benefits of both growers and harvesting companies. The reduction in uniformity with roller gin-type lint cleaners ranged between 0.2 to 0.8%, which was lesser as compared with saw-type lint cleaners. Introducing mechanical harvesting has always been a decades-long process. In Turkey, it took 20 years and in Greece, this process took place very gradually over a 15-year period. Top cotton producing countries like India, Pakistan, China, Uzbekistan and other developing countries like Iran Paraguay are still not using machine harvesting. The introduction of mechanical cotton picker or stripper can help improve quality and quantity of cotton picking thereby giving more benefit to growers in developing countries and improving their socio-economic status. The most controversial issue raised by the introduction of the mechanical cotton harvester is great migration as the machines eliminated jobs and forced poor families to leave their homes and farms in search for urban jobs. Therefore Government policies towards cotton harvesting mechanization must include the alternative jobs, packages for dependent manual cotton pickers and their families.

Social networks and scientific communication: A Review study

This study aims to emphasize the importance of developing the scientific communication system in line with the successive technological developments. Thus, this theoretical study deals with the concept of scientific communication in regard to various related points. These points are: the elements of communication, the types and forms of scientific communication, the concept of social networks, the emergence and development of social networks, the types of social networks. It also considers the most popular social networking sites, the use of social networks in scientific communication, knowledge of the advantages of using social networks in scientific communication, the obstacles to scientific communication within social networks, ways to overcome these obstacles, the role of free access in developing the process of scientific communication in the digital environment, the role of social networks and the free access usag in supporting scientific communication during the pandemic of Covid-19. Finally, this study found a variety of social networking services that support the process of scientific communication, which must be used, and to overcome any obstacles that may result from the use of these networks.

CRISPR Technology in Gene-Editing-Based Detection and Treatment of SARS-CoV-2

Outbreak and rapid spread of coronavirus disease (COVID-19) caused by coronavirus acute respiratory syndrome (SARS-CoV-2) caused severe acute respiratory syndrome (SARS-CoV-2) that started in Wuhan, and has become a global problem because of the high rate of human-to-human transmission and severe respiratory infections. Because of high prevalence of SARS-CoV-2, which threatens many people worldwide, rapid diagnosis and simple treatment are needed. Genome editing is a nucleic acid-based approach to altering the genome by artificially changes in genetic information and induce irreversible changes in the function of target gene. Clustered, regularly interspaced short palindromic repeats (CRISPR/Cas) could be a practical and straightforward approach to this disease. CRISPR/Cas system contains Cas protein, which is controlled by a small RNA molecule to create a double-stranded DNA gap. Evidence suggested that CRISPR/Cas was also usable for diagnosis and treatment of SARS-CoV-2 infection. In this review study, we discoursed on application of CRISPR technology in detection and treatment of SARS-CoV-2 infection. Another aspect of this study was to introduce potential future problems in use of CRISPR/Cas technology.

A SYSTEMATIC REVIEW OF THE ASSOCIATION BETWEEN ERYTHROCYTE INDICES AND STAGES OF CHRONIC KIDNEY DISEASE

Objective: To obtain the association between the erythrocyte indices and the stages of CKD. Material & Methods: This is a systematic review study conducted by searching for articles through PubMed, Proquest, and Google Scholar. Publication year are from 2010 to 2020. Results: There are 10 articles analyzed. There were 3 articles that showed a significant association and 2 articles that showed no significant association between erythrocyte indices and stages of CKD. Other article that used anemia morphology to represent the erythrocyte indices showed the normocytic normochromic as the largest percentage. 4 out of 5 articles with CKD patients who were known to be undergoing hemodialysis showed a significant difference in erythrocyte indices. Conclusion: There is association between the erythrocyte indices and stages of CKD.

A SYSTEMATIC REVIEW: THE ASSOCIATION BETWEEN URINE LEUKOCYTES AND THE TYPES OF URINARY TRACT INFECTION

Objective: This study aimed to determine the functional role of the urine leukocyte count on type of UTI. Material & Methods: This is a systematic review study with searches for articles from 2010-2020 through the PubMed, ProQuest, and EBSCO databases. The exclusion criteria in this study are patients using catheters (CAUTI), UTI patients in the Intensive Care Unit (ICU), and pediatric or infant patients. There were 1158 studies found and 3 studies synthesized. Results: There are 1130 patients studied. Age range from 18 to 89.1 years. Three studies showed that there was an association between the number of urinary leukocytes and the type of UTI (Tommaso Cai et al., p < 0.0001; and Alexander R. Levine et al., p < 0.001) and one study had no relationship. Conclusion: There is a relationship between the number of urinary leukocytes with the type of UTI. An increase in the number of urinary leukocytes above the normal limit is the sign of body’s immune response to eliminate uropathogens. The innate immune characteristic factors and the body’s immune response have an important role in causing symptoms in UTI patients.

Literature review: Perbandingan tingkat nyeri menstruasi (dismenore) sebelum dan sesudah dilakukan hipnoterapi pada remaja putri

Background: Dysmenorrhea can affect women who experience menstruation at any age. There is no age limit. Almost all women experience discomfort during menstruation, usually accompanied by nausea, dizziness, and even fainting. If it's like this, of course, menstrual pain should not be left alone. This dysmenorrhea can be overcome by pharmacological and non-pharmacological approaches. One of the non-pharmacological approaches that can be used is hypnotherapy.Objective: To determine the comparison of the level of menstrual pain (dysmenorrhea) before and after hypnotherapy in adolescent girls.Method: The method used in this literature review study is to obtain from a search of scientific research articles from the 2015-2020 period using the Google Scholar and Pubmed data bases. A total of 187 articles were obtained and then identification and screening were carried out, so that 10 articles were obtained that matched the inclusion criteria.Results: The average of the articles shows a pValue value <0.005 which means that there is a significant comparison and difference between before being given the intervention and after being given the intervention.Conclusion: There is a comparison of the level of menstrual pain (dysmenorrhea) before and after hypnotherapy in adolescent girls. It is recommended for educational institutions to provide information to all young women about hypnotherapy to reduce menstrual pain (dysmenorrhea).
