Abstract: This article analyzes today's results of the geography of export of fruit and vegetable products in our country. Proposals on finding new buyers for the export of fruit and vegetable products, maintaining a high quality level, and establishing "green corridors" between countries were previously requested. At the same time, the possibilities of growing, processing, storing and exporting fruit products in Samarkand region were highlighted. Also, recommendations on the organization of agroclusters, laboratories, logistics centers in the regions for the further development of this network in the future are presented.

Abstract: As a result of global climate change, the number of weather anomalies in the form of heavy rains is increasing, which increases the risk of emergency situations. Cities were flooded in the arid climate of Central Asia far from river floodplains and even in desert regions. Due to the change in the infrastructure of urban areas and the increase in the area of surfaces covered with asphalt and concrete, impermeable materials, the rate of water filtration into the soil decreases and the rate of slope water flow increases. Anthropogenic change in the urban landscape leads to the flooding of basins and their rapid flooding occurs, which increases the risk of emergency situations. The article proposes a method for calculating the flooding of urban areas from showers based on a mathematical model of slope runoff. The proposed mathematical model and method for calculating the planned slope runoff in cities differs from the quasi-planned model, which will make it possible to identify territorial zones, the rate of their flooding and develop design recommendations to prevent dangerous manifestations of heavy rainfall. The hydrological model makes it possible to calculate the flow of water flows in plan for various landscapes with different surface coverage - grassy, shrubs, trees, asphalt, concrete, and others. When carrying out construction activities to change the urban landscape, it is necessary to take into account the possibility of flooding zones during heavy rains, especially with an increase in the number and intensity of extreme weather events associated with climate change.

Abstract: The study investigated nutritional quality and sensory attributes of noodles produced from cocoyam root and wheat flour blends. Five different noodles were formulated as sample A – E with sample A 100 % cocoyam noodle as control. Proximate composition, mineral profiles, functional properties, antinutritional factors and cooking properties as well as sensory attributes of the cocoyam-wheat noodles were determined using standard analytical methods. Data obtained were subjected to ANOVA while Duncan Multiple range test was used to separate the mean where there is significant difference. Results showed that incorporation of wheat flour between 15 – 25 % with cocoyam flour to produce noodles improved its nutritional and functional qualities. Antinutritional factors of the cocoyam-wheat noodles significantly (p<0.05) reduced compare to 100% cocoyam noodle. The study shows that addition of 20 – 25 % wheat flour to cocoyam flour for the production of noodle increase its nutrition density, physicochemical and sensory acceptability.

Abstract: The treatment of chronic tibial osteomyelitis remains a problem, however many methods have been mention. In our study we aim to evaluate a unique approach of management using local debridement and antibiotic loaded calcium sulphate implantation for managing localized tibial chronic osteomyelitis.

Abstract: Soil geochemical survey of Songbe area, a typical tropical environment of Nigeria was carried out to determine the concentrations and distribution patterns of trace elements in order to decipher the underlying geology in the area, as a complimentary tool to geological mapping, especially in areas with little or no rock exposure. The soil samples were collected by driving a 1-meter auger down to a depth of 50 - 80 cm into the ground after removing the top soil, to ensure adequate penetration into the “B-horizon”. The samples were subjected to standard preparation and treatment prior to geochemical analyses performed using XRF and LA-ICP-MS at the Central analytical Facility, Stellenbosch University, South Africa. The point location maps were plotted using ArcView-Gis. The location point symbol map of each of the elements analysed revealed diverse pattern of distribution and showed considerable variations from one area to the other.  Some of these distribution patterns did not perfectly correspond with the inferred geological boundaries, especially in areas with thick overburden. The point symbol maps of  ferromagnesian minerals (Mg, Fe, Ni and  Cr) revealed anomalous and relatively high values in some areas underlain by quartzite, whereas anomalous and relatively high values of these ferromagnesian minerals are expected dominantly in areas underlain by mafic or ultramafic rocks. The symbol maps of tantalum and thorium showed dominantly low values for areas deduced to be underlain by charnockite with relatively high concentrations for pegmatitic bodies. The integration of the interpreted soil data with the point symbol maps of element concentration superimposed on the produced geological map showed that most of the inferred rock boundaries were over or underestimated and some mineral occurrences were yet to be accounted for.  Hence, it was concluded that multielemental chemical analyses using soil as sampling media is a vital tool to delineate underlying geology in the tropics and is an aid to geological mapping.

Abstract: The increasing spread of Lassa fever has generated concerns both among the dealers (processors and marketers) and consumers as to the path in the value chain through which it is spread. While some belief a major cassava product- gaari is the route, through improper processing techniques and storage which exposes it to rodents’ faeces and urine which when consumed becomes lethal and caused Lassa fever, others, especially the producers believe otherwise. The paper examines processors' and marketers' perceptions on information food safety about Lassa fever concerning cassava products processing and storage in Lagos state. Descriptive research design was adopted while a sample size of 120 participants were purposively selected from two LCDAs in Lagos state. A well-structured questionnaire was used for data collection. The data collected were analyzed with frequency, percentage, mean, standard deviation and t-test statistics. The results showed that the majority of the respondents were male (56.7 %,), married (48.3%), between ages 26 and above (79.4%) and majorly engaged in cassava mill operator services and wholesale of cassava products (59%). Mean monthly income and household size were 18,000.02(SD=1101.7) and 05 (SD=1.37). The study reveals that majority of the cassava products dealers perceived that information about contamination of cassava processed foods and the incidence of Lassa fever in Lagos state is gaining popularity. It recommended among other that early education of stakeholders will serve to curb the incidence of Lassa fever where wrong information could trigger and affect consumers' confidence.

Abstract: Given lesser energy consumption and required equipments, surface irrigation systems have is largely wide in irrigated fields. However, the simulation process of these systems has some specific complexities which has led to the development of several models such as hydrodynamic, kinematic wave, zero inertia and volume balance for optimal designing and managing surface irrigation. The main purpose of this research is to evaluate the results obtained from simulation of models present in SIRMOD (SM) and SRFR (SF) software through field information. This research was done in a four-section in the experimental field of university of Agriculture and Natural resources of Ramin (Khuzestan Province) and it was irrigated five times. The results of evaluations indicated that the "wave "Kinematic model has provided more acceptable results for "advance stage" and "infiltration process" in SM software (with respectively 8 and 4% of relative error) and therefore, it can be recommended for the conditions of the studied area and the surface irrigation of the "open-end border" type. Also for the regression stage, although the SF-KW model has better results (4% of relative error in contrast with 14%), given the relative advantages of SM software, and importance of prediction of infiltration process and moisture distribution of water in soil, this expectation is negligible in the ultimate selection.
