Environmental Impact Assessment of Cotton Ginning Agricultural Machinery

This paper realizes the hazards of chromium contamination and pollution caused in the use of chrome composite leather-clad(CCLC)rollers commonly used in cotton roller ginning industries and attempts to eliminate the chromium contamination and pollution during this environmental impact assessment(EIA)process.The cotton roller ginning process is the mechanical separation of cotton fibres from their seeds by means of one or more rollers to which fibres adhere while the seeds are impeded and struck off or pulled loose.Most of the cotton ginning operations are done using roller gins.The CCLC roller coverings contain about 18,000 to 30,000 mg/kg(ppm)as total chromium of trivalent and hexavalent forms which are toxic to human health.When the seed-cotton is ginned,due to the persistent rubbing of CCLC rollers over the fixed knives,the cotton and its products get contaminated with the total chromium of trivalent and hexavalent forms.Gin mill workers are exposed to the cotton dust and chromium pollution and are susceptible to health hazards such as premature death,cancer,byssinosis,and ulcers in cotton ginning air environment since toxic effects are produced by prolonged contact with airborne or solid or liquid chromium compounds even in small quantities.Noise pollution of agricultural ginning machinery in seed-cotton ginning mills has been found out to be 102-103 dB(A)decibel levels.To offset this problem,pollution-free rubberized cotton fabric(RCF)eco-friendly rollers for both the laboratory and commercial studies have been designed,fabricated and used in experiments in rollers gins.This nullifies chromium contamination and pollution during the complete process.Cotton technological parameters are well proven for commercial acceptance.

Investigation of the Ginning Process on ДП Series Saw Gin Stands

The article describes the research process of ginning, conducted at the stand of the saw gin of the DP series. The analysis of the roll box of saw gins of different companies was carried out, given the results of studies to determine the speed and density of the seed roll in the roll box of the saw gin. A diagram is given for the dependence of the speed of the feed rollers on the incoming signal.

Motes percentage and ginning outturn as affected with cotton cultivar and location

The present study was conducted to analyze cotton cultivar and location differences in motes, and to determine the relationships among these and ginning outturn. Therefore, the seed cotton of five promising hybrids namely;G.77 × Pima S6 and G.84 × (G.74 × G.68) growing in [Kafr El-Sheikh - Kafr El-Dawar - Etay El-Barood - Damietta], G.89 × Pima S6 growing in [El-Sharkia - El-Gharbiya - El-Dakahliya - El-Monofiya], G.83 × (G.75 × 5844) × G.80 and G.90 × Australian growing in [Sohag - El-Minia - Beni-Sueif - El-Faium] were used in this study. The results obtained indicate that the varieties exhibited different behavior responses to environmental conditions. On the whole, environmental factors associated with differences in place of growth, appeared to have much more influence on the number of motes than did varietal factors. Most of the locks for the promising hybrids at the different locations tend to cluster around the mean of 6 or 7 seeds per lock. There is a fairly marked tendency for the lock index, lint weight and lint percentage to decrease as the motes percentage increase. On the other hand, most of the promising hybrids under study tend to increase in the seed index as the motes percentage increase. However, the increasing in seed index as a result of the increasing in motes percentage for some cotton cultivars growing at different environments could be explain the difference in behavior for these cotton cultivars in lint percentage.

The Study of the Movement of Cotton Particles and Mathematical Modeling of the Impact of It at the Ginning Point

This article studied the principles of movements in the horizontal part of the newly constructed ginning camera, which is created by the authors, of the cotton particles. During the movement, the cotton particles get affected by pressing to various surface and forceful turbulent and horizontal movements of the surface. Some foreign mixtures and additional unnecessary objects get separated by the turbulence of the various surfaces and movement of the paneled stripes. Ginning efficiency and the quality of the cotton will be improved as the defects of the cotton particles are removed. “Cotton particle + net surface” movement principle of the Cartesian coordinate system was examined based on the rows of Cartesian coordinate system, by dividing all sides of the system by m weight and has the following second ordered multiple gender differential formula.

Opportunities for New Biorefinery Products from Ethiopian Ginning Industry By-products:Current Status and Prospects

The global demand for textile products is rapidly increasing due to population growth,rising living standards,economic development,and fast fashion trends.Ethiopian growth and transformation plan(GTP)gives high priorities for the textile and apparel sectors to transform its agriculturally led economy to an industrial-based economy.To achieve this,the number of tex-tile and apparel industries is rapidly expanding.However,the rapid growth in textile industry is generating mountains and mountains of by-products.In this review,possible applications of cotton stalk and cotton ginning waste in a variety of technologies and products are discussed in Ethiopian context.The finding of this study shows that Ethiopian current cotton cultivating area is about 80000 hm^(2),even though the country has a potential of about 3000810 hm^(2) land for cotton cultivation.From the current cultivated area,more than 240000 t of cotton stalk and 9240 t of cotton ginning trash have been generated as a by-product.But only a very little portion of the cotton stalk is being used as a raw fuel for household purposes and a small portion of cotton ginning trash is used for animal feed.Therefore,these underutilized lignocellulosic biomasses can be used as raw materials for producing different high-value biomaterials and thus country can perceive an economic and environmental benefit.A closer look at the structure and composition of the by-products shows that the whole part of cotton stalk and ginning waste can be used as a source of cellulose which can be exploited for conversion into a number of high-value biomaterials.Thus,conversion of the waste into valuable products can make cotton stalk and ginning by-products an attractive raw material for the production of high value bio-products.

Analysis of the Effect of GINS4 Regarding the Proliferation and Invasion of Breast Cancer Cells

Objective: To analyze the role and influence of the GINS4 gene in breast cancer progression and to explore its expression in triple-negative and non-triple-negative breast cancer cell lines. Methods: Single-gene analysis of GINS4 was performed by breast cancer RNA transcriptome data from The Cancer Genome Atlas (TCGA). Real-time quantitative polymerase chain reaction (PCR) was used to detect the expression of GINS4 in triple-negative and non-triple-negative breast cancer cell lines. The knockdown effects of GINS4 in MDA-MB-231 and MCF-7 cell lines on the proliferation and invasion of breast cancer cells were examined by cell counting kit 8 (CCK8) and Transwell assays. Results: Bioinformatics analysis showed that the expression of GINS4 in breast cancer was significantly higher than that in normal breast tissues (P > 0.05). At the same time, cell experiments confirmed that GINS4 was highly expressed in human breast cancer cell lines with normal breast cells as reference and in MDA-MB-231 and MCF-7 cell lines as reference, where the ability of proliferation and invasion of MDA-MB-231 and MCF-7 cells decreased after GINS4 knockdown. Conclusion: GINS4 is a gene associated with breast cancer malignancy, which can act as a novel tumor marker and has the potential as a new therapeutic target for breast cancer.
