ABSTRACT: Aim and Objective: Pneumonia is still a serious disease in most developing countries. Although, pneumonia can be treated with antibiotics but the issue of bacterial resistance to antibiotics leads to treatment failure. Therefore, there is the need to seek for alternative therapy of this infection. In this study, different extracts of Piper guineense (Seed), rhizome of Zingiber officinale and honey used to treat different ailments in folk medicine were examined for possible antibacterial activity on commonly encountered pneumonic bacteria in Ondo State, Southwest, Nigeria.  The seeds of Piper guineense (African Black Pepper) and rhizome of Zingiber officinale (Ginger) were separately extracted using ethanol, N-hexane and hot water according to standard methods. Susceptibility of selected pneumonic bacteria to the extracts and honey singly and in combinations was determined using agar diffusion assay. The MIC, the MBC and the phytochemical profile of the extracts were carried out using standard methods. The in-vitro antibacterial assay of the different extracts of seed of Piper guineense, rhizome of Zingiber offiniale and honey shows that they exerted growth inhibitory activity on the test pneumonic bacteria with zone diameter ranging from 6.25 to 21.25mm which was superior to the one mediated by control antibiotics (amoxicillin, perfloxacilin, ciprofloxacin and chloramphenicol) used with zone diameter ranging from 1.25 to 16.0mm.  Phytochemicals such as saponin, tannin, flavonoid, terpenoid, alkaloid and cardiac glycosides were detected in the extracts and honey. The findings showed that the different extracts of seeds of Piper guineense, rhizome of Zingiber officinale and honey exerted growth inhibitory activity that was superior to that of the antibiotics used against the test pneumonic bacteria in the in-vitro assay. Therefore the extracts has novel antibacterial properties that could be harnessed as alternatives for treating bacterial pneumonia.

Abstract: The mountains have a variety of tourist resources and a wide range of tourist activities. The Republic of Uzbekistan is distinguished by the attractiveness of its natural resources. Mountain-valley territories are characterized as areas with pronounced tourism potential. At the same time, the region is also attractive for foreign tourists. The formation of cross-border tourist zones in the field of tourism and recreation is a new socio-economic process associated with the beginning of the active development of international tourism in the world in the second half of the 20th century. The creation of transboundary ecotourism zones will significantly increase the level of international and national competitiveness of the ecotourism and recreational sector in the border areas of cooperation of each state.

Abstract: Single crossings corn hybrids SC 162 (yellow) and SC 10 (white) were cultivated at a rate of 71,400 plants per hectare using 35 kg of grains during the summer season in the north Delta, Kafr El-Sheikh Government, Egypt. The yield of the corn crop and plant parts (ears, stalks, and leaves) were estimated for each subplot and calculated per hectare. Whole corn plants were harvested after 90 days of planting at the dough stage of maturity, chopped to maximum length of 1-1.5 cm, and ensiled in plastic bags for 35 days. Representative samples of corn silage were analyzed for composition, fiber fractions, vitamins, and silage quality and used in gas and methane production to calculate gas parameters. Results revealed that almost all of the parameters analyzed remained nearly similar for yellow and white corn hybrid silage without significant differences. Whereas the contents of β-carotene and vitamin-A were significantly higher (p < 0.05) for yellow compared to white corn hybrid silage. We can predict the nutritional values of corn hybrids silage in terms of total digestible nutrients (TDN), digestible crude protein (DCP), gross energy (GE) and digestible energy (DE) from chemical composition. Also, we can predict the nutritional values in terms of feed intake, dry and organic matters digestibility, short chain fatty acids and microbial production and energy content from the in vitro gas Production. So, it can be predicted the nutritional values of corn silage easily and quickly in laboratory using the methods of chemical analysis and in vitro gas production.
