The availability of biomass waste poses the need for technical assessment of pelletisation of biomass waste at industrial production level. The misuse of environmentally friendly and sustainable energy resources and lack of compressed biomass energy products that could enhance fuel quality needs to be addressed. This study intends to determine the energy output from tenary combination of the biomass fuel pellets consisting of rice husks, African birch sawdust, corncobs and their varying mixtures bond with aqueous extract of C. populnea (Cp) and M. esculenta (Me). The combustion characteristics of pellets produced from Rice Husk, African Birch Sawdust, Corncob and their blends (M, M1, M2, M3 and M4) were conducted by the development of an analytical protocol. Pellet admixtures were prepared at each binder ratio of 10% of bulk weight of RH, ABS, corncob and their various blends in the ratios 1:1:1 (M), 1:2:3 (M1), 2:1:3 (M2), 3:1:2 (M3) and 2:3:1 (M4), respectively. The Bulk Density (BD), Ash Contents (AC), Heat Release Rate (HRR) and Calorific Value (CV) of the pellets were measured using established procedures. The result revealed that combustion characteristics of fuel pellets made from Corncob and Blend ratio of 1:2:3 bound with Manihot esculenta gel were enhanced and the fuel pellets possessed sufficient calorific values suitable for energy applications. It was recommended that massive production of fuel pellets from biomass wastes for small and medium scale energy systems could give a positive development to agrarian and rural areas in Nigeria where there is a lot of these resources and lack of stable electrical supply.","PeriodicalId":506697,"journal":{"name":"INTERNATIONAL JOURNAL OF MULTIDISCIPLINARY RESEARCH AND ANALYSIS","volume":"39 22","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141662060","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Red dragon fruit (Hylocereus polyrhizus) is a fruit that is rich in antioxidants that inhibit ROS and prevent damage to liver cells by cigarette smoke. This study aims to assess the effect of administering red dragon fruit juice on liver microscopic images in Wistar rats exposed to cigarette smoke. It was an experimental study with a post-test-only control group design. Thirty-five male Wistar rats (Rattus novergicus) were randomized into five groups. Four groups were exposed to cigarette smoke (K-, P1, P2, and P3), and the fifth group was used as a control (K). All the P-groups were given red dragon fruit juice 2 g/2.5 ml, 4 g/2.5 ml, and 8 g/2.5 ml, respectively, for twenty-eight days. On the 29th day, the livers of Wistar rats were taken for preparation and microscopic observation. The research data were analyzed using the Kruskall-Wallis and Mann-Whitney post hoc tests to determine group differences. The average liver cell damage in K, K-, P1, P2, and P3 were 1.23, 2.51, 1.57, 1.51, and 1.43, respectively. There was a significant difference in damage between the K- group and the P1 (p = 0.002), P2 (p = 0.004), and P3 (p = 0.002) groups.

{"title":"Exposure to Particulate Matter Affects Lung Function and Performance: A Literature Review","authors":"I. M. K. Wijaya, Putu Adi Suputra","doi":"10.47191/ijmra/v7-i07-07","DOIUrl":"https://doi.org/10.47191/ijmra/v7-i07-07","url":null,"abstract":"Air pollution has emerged as a significant peril to public health on a global scale, with around five million deaths occurring each year as a direct result of air pollution. The respiratory system mostly absorbs air contaminants, which then enter the alveoli and circulate in the bloodstream. Exposure to particulate matter (PM), the primary pollutant, can lead to acute inflammation of the respiratory tract and exacerbate pre-existing chronic lung inflammation. The extent of damage produced by particulate matter (PM) is determined by the manner in which the particles enter the lungs, including factors such as their aerodynamic diameter, ambient air velocity, and respiratory rate. Additionally, the manner in which the particles depart the lungs, involving processes such as nostril hair, mucociliary clearance, and macrophage phagocytosis, also plays a role in determining the damage caused. During periods of low air quality, particulate matter (PM) can negatively impact the immune system by causing damage to the bronchial mucociliary system. This damage makes it harder for the body to eliminate pathogens and leads to the release of inflammatory cytokines, which can harm lung epithelial cells and fibroblasts. Additionally, it inhibits intercellular communication within the gaps of the epithelial barrier, hence reducing its efficacy as a protective barrier for the lungs. The detrimental effects of PM can be attributed to oxidative stress caused by free radicals. PM has the ability to directly stimulate macrophages, leading to inflammation and an increase in the production of reactive oxygen species (ROS). Reactive oxygen species (ROS) impair antioxidant defenses and inflict damage on DNA, proteins, carbohydrates, and lipids. Lung function will decline as a result of bronchoconstriction, pulmonary edema (which leads to thickening of the alveolar capillaries), and fibrosis (which restricts lung expansion) caused by epithelial thickening. Based on the findings of many research, it may be inferred that an excessive influx of particles can lead to an excessive burden on the lungs, consequently impairing the respiratory system's defense capability and potentially resulting in lung damage. These investigations have established that higher levels of exposure to particulate matter are linked to a larger likelihood of reduced lung function. On the other hand, decreasing the amount of these particles that one is exposed to will reduce the danger.","PeriodicalId":506697,"journal":{"name":"INTERNATIONAL JOURNAL OF MULTIDISCIPLINARY RESEARCH AND ANALYSIS","volume":"10 7","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141660042","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
