Abstract: Sugarcane is one of the cultivated crops in Bangladesh for centuries. In addition to running one of the most important agro-based industries, it also runs the sugar industry. In order for sugarcane to be healthy, potassium (K) and zinc (Zn) must be present in its diet. According to estimates, no other material is as abundant as potassium (K) in the plant’s cell sap. The potassium content of a sound sugarcane crop is generally between 180 and 240 kg per hector. Potassium (K) is one of the primary elements that provide sucrose which comes from the leaves to the storage tissues. The hydration and osmotic concentration within the stomata guard cells is done by Potassium (K). Zinc (Zn) performs different functions in plants, such as taking part in different kinds of biological oxidation-reduction, activating metal in enzymes, metabolism of carbohydrates, synthesis of RNA, integrity of biological membranes, and stalk maturation, providing active counteraction to infection by pathogens and ultimately increase crop yield and quality. The aim of the work is to evaluate the effect of utilizing zinc in sugarcane cultivation. Positive results are obtained. Zinc incorporation also increased the CCS%. 8 kg/ha zinc with the recommended dose of NPK fertilizer is good from an economic perspective.

Abstract: Reactive dye, the most frequently used dye for cotton coloration due to its superior technical aspects, especially its uncut covalent bond with the fiber, show poor fastness properties because of unfixed or hydrolyzed dyes on the fabric surface. Several fixing agents were investigated to improve the fastness properties, while some are not eco-friendly. However, instead of harmful chemicals, the formaldehyde-free fixing agents Optifix RSL, Albafix FRD, Optifix EC, and Albafix ECO were used in this study to enhance the fastness properties. These agents were applied on reactive dyed cotton knit fabric at 0.5%, 1.0%, and 1.5% concentration, and different fastness properties of treated fabric were investigated, namely colorfastness to washing, rubbing, and perspiration. In most cases, treated fabrics showed better fastness properties than untreated ones, whereas 1% concentration yielded better than 0.5%, and no improvement was found with further increasing the concentration of the fixing agent. Moreover, the mentioned fixing agents had little effect on shade, and this phenomenon was also inspected in terms of ∆E and K/S values. Quaternary ammonium compounds (Optifix RSL and Albafix FRD) performed better stability regarding shade than aliphatic polyamine compounds (Optifix EC and Albafix ECO), and this change appeared slightly yellowish to blueish.

Abstract: As the rate of death due to cancer is increasing in the world, the world is paying much more attention to effective treatments for cancer. Teletherapy is a type of treatment that delivers radiation to cancer cells from a specific distance. The focus of this study is exclusively on Cobalt-60 teletherapy, which has recently been installed at the Secondary Standard Dosimetry Laboratory (SSDL) of the Bangladesh Atomic Energy Commission to provide quality assurance and quality control services for all radiotherapy machines in Bangladesh. Our objective is to conduct a series of measurements that are necessary for the commissioning and acceptance of the installed Cobalt-60 machine (Equinox 100). The measurements include some mechanical parameters, including the accuracy of a variety of indicators and the size of the fields, before the measurement of dosimetry with two protocols, TRS-277 and TRS-398. We have found 0.16?viation in the accuracy of the optical indicator, 0.04?viation in the accuracy of the collimator angle indicator, and 0.06?viation in the accuracy of field sizes throughout the study. We have found no error in the accuracy of the gantry indicator. In this work, the focus is primarily on mechanical calibration to ensure that a dosimetry plan that is practical and accurate is being developed for the treatment of cancer patients. The output of this study may contribute to the development of treatment planning systems for cancer treatment.

Abstract: A traditionally deterministic algorithm for quicksort is used which gives O (n log n) running time for an average case and O (n2) for the worst case, where n is the number of elements to be sorted. If a randomized approach is used the worst-case running time is reduced to O (n log n). The median of three approaches for choosing pivot and multi-pivot approach like dual pivot also improves the running time. In this paper, we analyze the effectiveness of various pivot positioning methods. To achieve this, we take randomized generated and shorted array of different sizes which provide us with enough data to conclude.

Abstract: The core-spun yarn has gained much concern and popularity all over the world for having elastic and comfort properties. The draft ratio of the core, the number of cores, and the type of sheath material are the prime parameters of producing core-spun yarn. These parameters influence the physical and mechanical properties of the yarn. In this study, the effect of the number of core-spun yarn cores was investigated on the yarn’s physical and mechanical properties. Two types of core-spun yarn were produced: single core-spun yarn and dual core-spun yarn. Cotton fibers were used as a sheath, and spandex monofilament and polyester multi-filament were used in the core. It was revealed that dual core-spun exhibits lower unevenness, imperfection, and hairiness value than single core-spun yarn. In addition, the bundle strength of yarn was found higher in dual core-spun yarn.

Abstract: It is a great challenge for textile spinners to ensure the quality of ring-spun blended yarn (CVC) with smooth production. 30 Ne blended yarn (Cotton and polyester at the ratio of 60/40) was produced during this research work because it is a more frequently used count for blended yarn. Different parts of the Ring Frame influence the quality of yarn. Among them, the role of the spacer is significant as it controls the movement of fiber during drafting at Ring Frame. This study introduced three spacers of different sizes (2.3 mm, 3.1 mm and 5.1 mm) by keeping the same raw materials and setting parameters for mentioned yarn count. Spacer size 3.1 mm showed the outstanding properties of yarn in terms of unevenness, imperfections and hairiness compared to the other spacer sizes. There is no significant changes in the blend ratio for changing the spacer. This work has the potential to select the appropriate spacer size (mm) that will help textile technologists during decision-making.

Abstract: Contemporary garment enterprises must exhibit remarkable adaptability to create diverse styles and types of clothing in response to market demands for their survival. Enhanced excellence across all dimensions justifies optimum pricing. In competitive marketplace, cost calculation of garment not only optimum for net profit generation but also necessary to avoid order rejection. During the initial stages of order acquisition, fabric consumption estimates must be established using mathematical approximations before actual marker creation. Among the two commonly employed mathematical methods for fabric consumption, the alignment of specific formulas with particular garment types has not been thoroughly analyzed. The aim of this study is to identify the most accurate method of fabric consumption for various garment categories. For this purpose, six distinct garments have been selected for experimentation: two woven shirts (short and long sleeves) and four knit T-shirts (including two set-in sleeve variations with long and short sleeves, and two raglan sleeve variations with long and short sleeves). Pattern making and grading were executed using specification sheet measurements, followed by marker creation utilizing Boke CAD software. Subsequently, fabric consumption for all six garments has been compared using 3 fabric consumption methods: one marker planning method and two mathematical methods. Although the marker planning method is well-established as the most accurate means of fabric consumption determination, its usage requires pattern and marker preparation prior to production. This limitation necessitates the use of mathematical formulas during the preliminary stages for cost calculations and order processing. The comparative analysis highlights that neither mathematical formula is universally suitable for all garment types, suggesting that specific formulas should be applied to distinct garments. As such, this guideline serves as a valuable industry resource, preventing unnecessary fabric wastage caused by misusing mathematical formulas and thereby contributing to sustainability efforts.
