Abstract: The present investigation was carried out to characterize and classify some typical healthy and declined Nagpur mandarin gardens in Warud and Morshi tahsil’s of Amravati District (M.S.). Total forty two representative surface and depth wise soil samples from healthy and declined Nagpur mandarin gardens were collected and analyzed for various physico-chemical properties. The findings revealed that the texture of soil is clayey (40.0 to 59.0 per cent clay in healthy gardens and 47.4 to 61.4 per cent clay in declined gardens). The bulk density and porosity in healthy gardens varied from 1.51 to 1.67 Mg m-3, 35.85 to 43.02 per cent and in declined gardens, it varied from 1.51 to 1.66 Mg m-3 and 25.85 to 43.02 per cent respectively. The pH, organic carbon and CaCO3 content in healthy gardens soils varied from 7.50 to 8.0, 4.80 to 9.00 gm kg-1, 5.35 to 8.31 per cent and in declined gardens, it varied from 7.7 to 8.2, 1.95 to 3.75 gm kg-1, 6.71 to 10.53 per cent respectively. The electrical conductivity and cation exchange capacity of healthy gardens soil varied from 0.21 to 0.28 dSm-1, 45.92 to 55.53 cmol (p+) kg ha-1 and in declined gardens it varied from 0.22 to 0.32 dSm-1, 46.20 to 51.92 cmol (p+) kg ha-1 respectively. No significant difference was found in clay, bulk density, porosity, electrical conductivity and cation exchange capacity in healthy and declined gardens, however soil reaction was high in declined gardens than healthy gardens. Organic carbon content was high in healthy gardens than declined gardens and free lime content was found low in healthy gardens than declined ones. Depth wise distribution showed that bulk density, pH and electrical conductivity increase with soil depth. Organic carbon and cation exchange capacity decrease with soil depth. The available nitrogen, phosphorus and potassium content of healthy gardens surface soils varied from 206.0 to 273.7 kg ha-1, 25.0 to 38.3 kg ha-1, 324.0 to 672.0 kg ha-1 and in declined gardens it varied from 135.4 to 206.8 kg ha-1, 19.8 to 23.3 kg ha-1, 364.0 to 750.4 kg ha-1 respectively. Available nitrogen and phosphorus content in healthy gardens found more supporting than declined ones. Depth wise distribution showed that available nitrogen and phosphorus showed decreasing trend with the soil depth.

Abstract: Transfusion-Transmissible Infections (TTIs) include human immunodeficiency virus (HIV), hepatitis B virus (HBV), hepatitis C virus (HCV) and syphilis that are transmitted from person to person through parenteral, administration of blood or blood products leading to serious health problems. The present study was lab based cross-sectional study conducted from February 2018 to August 2019 to investigate the prevalence of hepatitis B, HIV, hepatitis C, and syphilis among the foreign departing employees from Itahari, Sunsari, Nepal. The samples were screened for the presence of anti-HIV IgG, HBsAg, anti-syphilis and anti-HCV IgG using commercial rapid test kits following standard protocols. A total of 4260 samples processed, the overall seroprevalence of TTIs was found to be 1.22% (52/4260). Seroprevalence of HIV was found to be 0.05% (2/4260), HBV was found to be 0.53% (23/4260), HCV was found to be 0.18% (8/4260) and syphilis was found to be 0.45% (19/4260). Among the transfusion transmissible infections in individuals going for foreign employment, the most prevalent was found to be hepatitis B (0.53%). In overall, the TTIs infection was most prevalent in the age group of 24-29 (0.35%) and 30-35 (0.35%) years. Further investigation including studying the prevalence of TTIs in general population is required to address the issue and to formulate proper preventive, diagnosis and treatment procedures of these infections.

6. A Bio-Inspired Reward-Based Message Forwarding For Vehicular Social Network
Author(s): Aklilu Mandefro Messele

Abstract: The Ants capability of working together and their way of message transmission makes us inspired especially their cooperation for their common goal and dropping down pheromones which used as a trail for themselves and for others. We would use Ants broadcasting method for drivers’ cooperation and message forwarding. Therefore if there were any driver who couldn’t broadcast any emergency message related to car accident like Ants done to locate the food source, could be considered as a selfish node and couldn’t be rewarded as cooperatives do. The previous vehicle to vehicle communication or message forwarding schemes that was tried to motivate cooperative drivers used incentive methods in which it is not motivating all participant nodes and some of them used punishment methods. These types of methods are not effective to stimulate selfish drivers. We conducted the research using embedded traffic simulation in which it includes mobility and network simulation capabilities merged together and served as multi-functional software. From the tools falling into the embedded category is National Chiao Tung University network simulator (NCTUns) which provides a full range of network stack simulation tools. Watchdog was our selfishness detection method, in which the RSU controls whether nodes are cooperative or not because the (Road Side Unit) RSU knows where the nodes were located and in which path they are drive and what messages they broadcasted. The rewarding model we used is paying per packet. The payment principle is for each successfully transmitted unit-sized packet, each of N intermediate nodes should receive λ credits, whereas the service provider (SP) would pay λ ∗ N in total. The proposed solution was evaluated by the three performance metrics which are dropped packets, selfishness detection method and delivery ratio. Based on our experiments result the number of accident increased as the number of total nodes increased in the same simulation area. As the number of nodes participated on the area increases the probability of having an accident increases and the probability of stimulating selfish nodes increased using the same incentive method and amount because there is a probability of accident commit increases and the rewarding and acknowledgement messages also increases in which it can stimulate the selfish nodes.

Author(s): Parreno J,Cempron B, Bucog N, Pepito M and Zamora C.

Abstract: Weeds in agricultural system are becoming problem nowadays in which it reduces yield of many crops. Synthetic herbicides are usually used to control weed growth. Meanwhile, using herbicides creates hazardous impacts on agricultural products and also increases environmental pollution. Thus, this study aimed to evaluate the allelopahatic potential of Castor plant (fresh leaves, dry leaves, seeds) aqueous extracts on germination rate, germination value indices and root growth on selected crop species. The inhibitory effects of allelochemicals might be used against weeds as a controlling tool for decreasing weed emergence in field conditions. The study consist of 4 treatments replicated 5 times within 7 days. Germination rate, germination value indices and root length were collected in the 7th day of the experiment. Data gathered were analyzed using one way ANOVA and tukey HSD for comparison. Based on the results, it shows that fresh leaves and seed aqueous extract had an allopathic effect on the seed germination and germination value of Zea mays L. and Solanum lycopersicum. In terms of root length inhibition, all treatments had an inhibition effect on the selected crop species. The result showed great potential for the natural herbicide from the determined parts of identified plant.

Author(s): Esayas Alemayehu, Alemayehu Wubie, AbelnehYimer and YaredTigabu

Abstract: Evaluation of integrated agriculture aquaculture (IAA) was conducted on station in the National Fisheries and Aquatic Life Research center (NFALRC), Sebeta. In this trial the effect of irrigation with pond water and spring water and application of inorganic fertilizer on yield and other parameters for Tomato (Lycopersiconesculentum) and potato (Solanum tuberosum) were evaluated using randomized complete block design with three replications. Results show that there is variation in total yield and marketable yield as well as clusters per plant of tomato with plots treated with fertilizer having higher values. Among examined parameters, only clusters per plant of tomato varied significantly (P<0.05) among treatments. However, marketable yield and yield per plant did not show significant variation (p>0.05) among treatments. Nevertheless, all parameters in this trial did not show significant difference among treatments (P>0.05). The results of this trial indicate that using pond water to irrigate horticulture plots can partially replace the use of inorganic fertilizers thereby reducing both cost and environmental effects.

Author(s): Nuhu A. Sansa

Abstract: Recent different literature argued that China’s agriculture sector contribution to economic development is deteriorating. The agriculture sector contribution with regard to Agriculture GDP contribution, agriculture employment, and foreign exchange earnings were decreased. The present study is undertaken to investigate the contribution of industrial policies to the Agriculture sector of China during the period from 2007 to 2018. Simple regression model employed as a methodology to investigate the contribution of industrial policies to the agriculture sector in China during the period from 2007 to 2018. The data of all agriculture macro economic variables applied in this study (Economic openness, Agriculture GDP, Agriculture Food Production, and Employment in Agriculture) were collected from the World Bank for the whole period from 2007 to 2018. In order to investigate the contribution of Industrial policies to the agriculture sector in China, industrial policies were represented by the economic openness which stand as independent variable, while agriculture GDP, Agriculture food production and employment in agriculture were dependent variables in the study. The information discovered in the study were in actual fact catching the attention. Information discovered as a result of the investigation shows that relationship between Economic openness and Agriculture GDP is Negative, While the relationship between economic openness and other Agriculture macro economic variables (Agriculture Food Production and Agriculture Employment) is Positive and meaningfully during the period from 2009 to 2018 in China. That means Industrial policies had meaningful contribution to Agriculture Food production and Agriculture Employment, While Industrial policies had no contribution to Agriculture GDP during the period from 2009 to 2018 in China.

Author(s): Hiba J. Ahmed, Asaad A. Kamil, Ammar A. Habeeb and Nabeel A. Bakr

Abstract: In this study, Cu2CdSnS4 thin films were deposited on glass substrates at fixed concentrations: 0.02 M of (CuCl2.2H2O), 0.08 M of CS (NH2)2 and 0.01 M of both SnCl2.2H2O and (CdCl2.2H2O) using Chemical Spray Pyrolysis (CSP) technique at different deposition temperatures (300, 350, 400 and 450) °C. The thickness of all samples were (300 ± 10) nm. X-ray diffraction patterns showed that all films have a tetragonal structure with a preferred orientation of (112). The maximum value of the crystallite size was 8.09 nm at 400 °C deposition temperature. Raman spectra analysis confirmed the purity of the film peaks located at (332-333). The FESEM micrographs showed that the nanostructures appeared in the form of cauliflower. The highest average grain size was 62.8 nm for the film deposited at 300 °C substrate temperature. The optical properties of all films were studied by recording the transmittance and absorbance in the wavelength range (400-900) nm. The results showed that absorption occurs in the visible and ultraviolet regions. Through the Tauc’s equation, the optical energy gap was calculated for the allowed direct transition. Its value was in the range (1.59-1.40) eV. Therefore, these films are suitable for use in solar cell applications. Hall effect results showed that Cu2CdSnS4 thin films are p-type and the highest conductivity was 0.288 (Ω.cm)-1 at 400 ˚C corresponding to the maximum mobility value and the highest charge concentration.

Author(s): Shunmuga Sundaram G, Suresh Kumar R S, Taye Cherga and Dersolegn Yeneabat

Abstract:Criminal investigation is an art of uncovering the truth for the purpose of successful detection and prosecution. A successful and reliable investigation to stand for the justice requires a competent investigator and the use of technological aids from forensic and other scientific disciplines. This paper investigates the common perception among the police officers at different designation levels working in the Gamo region, SNNPR on the application of forensic services in crime investigation. The major objectives of this study are to a) Identify the level of awareness on forensic service among the crime investigation officers and b) To identify the lacunae in implementation of forensic services in crime investigation process. The sample size of 70 police officers in all categories of Constable, Sub- Inspector, Inspector, Deputy Commissioner in the Gama zonal region were included as respondents of the study. A purposive sampling method was adopted and structured questionnaire was used for the data collection. Statistical interpolation of the results was done using SPSS software. This study identified the lack of awareness among the police officers working in lower hierarchy level (<50%) on various forensic services, specialized forensic divisions, and application of forensic approaches during crime investigation. A positive correlation was observed with respect to the designation of officers and the lack of awareness among the police officers. Majority (<65%) of the police officers were not aware of the existence of fingerprinting division in the country. There exists a poor communication between key actors in the criminal justice system and financial resources not directed at the front end of the forensic process. The outcomes of this study would facilitate the identification of the lacunae in implementation of forensic services in the crime investigation process. This study emphasizes the need for immediate attention on managing the forensic illiteracy among police officers, mainly on the field such as fingerprint analysis, criminal investigation methods and cyber crime. It is the need of hour to promote the establishment of forensic wing at Gamo zonal level law enforcement.
