Application of Several Post-Harvest Processing Technologies to Several Types of Coffee Plants (Coffea sp)
Get PDFSo far, post-harvest processing of people\u27s coffee is usually always a drying process using sunlight, the drying process is usually carried out for 15 to 17 days until a moisture content of 18 to 20% is reached. But if the rainy season takes up to 3 weeks more and this results in the quality of the coffee being not good because it is moldy and smells bad. In post-harvest handling, especially the drying process remains a problem in the field. Post-harvest processing of coffee in the small and medium coffee industry usually uses several methods, including: honey process, honey wet hulling process, natural process, full wash process, semi wash process and wine process. In addition to the processing after harvest, the type of variety harvested also greatly affects the quality of the crop. Arabica and Robusta coffee plants provide different tastes, aromas, levels of acidity for coffee lovers so that there is competition for market interest which also encourages farmers to plant Arabica and Robusta coffee. The purpose of this research is to get the best post-harvest coffee processing method according to the taste expected by consumers. From the research that has been done, it can be concluded that the processing method greatly influences the taste of the coffee, both Arabica coffee powder and Robusta coffee powder. The best post-harvest processing of coffee according to the taste expected by consumers with the honey method for both Arabica and Robusta coffee. This is influenced by the mucilage in coffee beans containing mucilage which gives rise to its own taste in the final result of coffee powder

In brief, it is crucial to enhance teachers\u27 sense of responsibility toward their students, as it can ultimately result in enhanced academic achievement and personal development for students
Contribution to the Taking into Account of Environmental Factors of Vulnerability of Reinforced Concrete Buildings in the City of Douala-Cameroon
Get PDFThe environment of the city of Douala (humid, porous, sandy-clay soil), plays a determining role on the vulnerability of reinforced concrete constructions, by effects of corrosion of degradations, and destructions of the structures (buildings). Relative Y, the method tree of the causes and the tests pH-metric, granulometric and permeameters , allowed us to seek, to check and to analyze certain environmental factors impacting on the constructions, weakening the concrete and pari cochet , the resistance and the durability of the buildings. To this end, the pH tests of groundwater, springs and industrial discharges, containing chloride ions (Cl-), sulphates and carbon dioxides from heavy rainfall and flooding, attack by an electrochemical mechanism the reinforcement and framework of the constructions. Thus, the results obtained from the tests, demonstrate how the dangerous acids present in water, penetrate into the reinforced concrete to destroy it. The resulting chemical reaction of hydration absorbs the water and swells the concrete to reach the steel, weakening it and destroying the protective film (passivation). The action of water on concrete is declined by absorption, hydrolysis, dissolution, solvation and crystallization. Also, the corrosion rate of materials remaining strongly inherent to the high humidity and PH level ? 6, directly influencing the electrical resistivity conductivity and diffusion of oxygen and carbon dioxide in concrete.
As such, the relative humidity (RH) or high water content in concrete and the environment of the site receiving the construction project, produces permeability decreasing effects in the presence of oxygen. These effects contribute to stimulate and increase the corrosion process. Because, water, soil and industrial pollutants, affect the works Given, that it is demonstrated that a quasi-permanent moisture content ? 55% in a porous material such as concrete, leads to the loss of 20 to 30% of its cohesion. Hence, the various forms of degradation and loss of loads suffered by the constructions. To this end, the binder content, mineral additives and the water/cement ratio (W/C), are to be considered for the evaluation, resistance and durability of the constructions. Also, most of the methods used to determine the permeability of porous materials are based on Darcy\u27s law. This is because, in its basic form, the fluid flows through a disc-shaped sample under a pressure gradient. Consequently, in addition to the requirement of carrying out geotechnical studies of materials and soil in accordance with the standards of construction and urban planning, pH metric tests are necessary for the effective consideration of environmental factors to achieve the resilience and durability of reinforced concrete structures. It will be in particular: ( i ) to identify and analyze the impacts of water and soil on reinforced concrete constructions; (ii) to verify and analyze the compliance of the said constructions with the geotechnical and urban planning standards (realization of geotechnical studies and the use of adequate quality materials and qualified manpower); (iii) to contribute to the considerable reduction of the vulnerability of the works to the attacks of the sulphates , for a better safety and durability of the constructions
Asian-Canadian Literature Between: Quasi-Shakespearean Syntax and Deaf Culturalists
Get PDFThe first reading of Asian-Canadian narratives like Joy Kogawa’s Obasan, Hiromi Goto’s Chorus of Mushrooms and Shauna Baldwin’s What the Body Remembers might lead the reader to think that there is but one single dominant theme that one can call it “diasporic melancholia”, yet this is way too confusing. One can underline the overwhelming presence of the two notions of “exile” as well as “silence”. This paper seeks to shed light on the theme of “silence” not only as a consequence of the “diasporic melancholia” characterizing the different characters exposed in contemporary Asian-Canadian literature, but also as a feature distinguishing such ethno-racial stereotypes as “deaf culturalists” and also brings to light an Asian-Canadian quasi-Shakespearean syntax attempting to characterize ethnic minorities’ hybrid identities
Butyrate Induces Production of Heat Shock Protein 27, 70 and 90 and Protects Against Carbon Tetrachloride Hepatotoxicity in Rats
Get PDFThe liver plays important roles in the body including blood cell formation, metabolism of carbohydrates, proteins and lipids, detoxification, bile production and excretion, and hepatic regeneration. It is however prone to various hepatotoxins that cause damage and diseases including consumption of alcohol whose toxicity is at an alarmingly increasing prevalence globally. Since both butyrate and heat shock proteins (Hsps) can protect various body systems against several perturbations, we investigated whether butyrate protects the liver against carbon tetrachloride (CCl4) hepatotoxicity via production of Hsps. Rats were treated with sodium butyrate (SB) for 8 days then CCl4 on the 8th day and sacrificed 1 to 2 days later. Sacrificed animals were autopsied, liver samples taken, fixed in formalin and routinely processed. Tissue sections were stained with haematoxylin and eosin or anti-Hsp90, Hsp70 and Hsp27 monoclonal antibodies to assess morphological changes and expression of Hsps. Pretreatment with SB reduced the severity of CCl4 induced hepatotoxicity which was associated with expression of Hsp90, 70 and 27. It is concluded that the protective potency of butyrate against CCl4 hepatotoxicity is mediated, at least in part, through overexpression of Hsps
Oxidative Stability of Fish Oil And Impact of Oregano Essential Oil on The Prevention of Lipid Oxidation-Study By FTIR-Spectroscopy
Get PDFThe thermal stability and fatty acid composition of oregano fish oil (FIO) was studied by comparing; pure fish oil, fish oil with 1% oregano oil, fish oil with 2% oregano oil, applying FTIR (Fourier - Transform Infrared) - spectroscopy and GC /MS (gas chromatography - mass spectrometry). The physico-chemical parameters analyzed (value of peroxides, value of iodine (g) and value of acids (mg/g)) have resulted in significant changes in different components of the composition of the year of origin fish, the value of peroxide (mmol/ kg) for pure fish oils, oils with 1% oregano oil, and with 2% oregano oil. Then the iodine value (g) for pure fish oils, oils with 1% oregano oil, and with 2% oregano oil as well as the acidity value for pure fish oils, oils with 1% oregano oil, and with 2% oil oregon.
FTIR spectroscopy is an analytical device (method) which clarifies the basic principles of the mechanism of stereo-chemical changes in the analyzed substances, as well as to understand which of the chemical components are responsible for increasing the thermal stability of fish oil.
In this study, in addition to the above-mentioned parameters, it was found that temperature (°C) is adequate for increasing the stability of origin fish oil, because this phenomenon corresponds to the processes when oxidation reactions and Maillard reactions form compounds with maximum antioxidant activity (lipid stability)
