Co-hort study of urinary schistosomiasis among two villages residing along Hadejia Valley, Jigawa State, Nigeria

A study was carried out to determine prevalence of urinary Schistosomiasis among two villages located along Hadejia valley in Jigawa State, Nigeria. A total of 125 urine sample from people residing in each of the two villages (Yamidi and Shawara), were screened for the presence or absence of S. haematobium eggs. Urine sample were screened using Concentration Sedimentation Technique. The overall prevalence of S. haematobium infection in Yamidi was 76.8% with mean Eggs per cubic Centiliter (EPC) of 2.9, and in Shawara the overall prevalence was 77.6% with mean EPC of 3.4. Males were found to be more infected than female in both the two villages. People aged 1 to 5 years have highest prevalence of the infection in both the two villages than people among older age group. People with haematuria have highest prevalence of 95.1% and mean EPC of 6.0 than people without haematuria that have lower prevalence of 72.0% and mean EPC of 3.4.There was no significant relationship (p > 0.05) between the infection and presence or absence of haematuria. This study has established that urinary schistosomiasis is endemic in the study area.Keywords: Hadejia, Haematuria, Infection, Jigawa, Nigeria, Schistosomiasi

Prevalence of fasciolosis among cattle slaughtered at Hadejia Abattoir

A study was carried out to find out the prevalence of Fasciolosis in cattle  slaughtered at Hadejia Abattoir. Fasciola gigantica is a parasite of liver and bile duct in cattle, sheep and goat. The liver was examined for Fasciola by making length wise incision on the ventral side of the liver in such a way that the Bile duct was cut open. The forcep was used to pick the exposed worms in the bile duct and the Gall bladder. The Flukes recovered from each cattle were placed in label containers and taken to the Laboratory for identification and preservation. A total of 545cattle were  examined for the presence or absence of Fasciolosis in Hadejia Abattoir. Out of this number 279 (51.2%) were males and 266 (48.8%) were females. The overall  prevalence of Fasciolosis in the study area was 159(28.0%). The prevalence of Fasciolosis in males was found to be 73(26.2%), while the prevalence in females was 79(29.7%). There was no significant relationship (P > 0.05)between sex of the cattle and prevalence of the infection. The Prevalence of Fasciolosis in adult cattle was 36(40.2%), while in young cattle the prevalence was 123(15.0%). There was significant relationship (P < 0.05) between the age of cattle and prevalence of the infection.Fasciolosis is one of the helminths diseases that were found to be prevalent affecting cattle in the study area.Key words: Abattoir, Cattle, Cross-sectional., Fasciolosis, Slaughter

Performance Analysis of Concurrent Transmission with Reducing Handshakes in Multi-Hop Wireless Mesh Networks (WMNS)

The IEEE 802.11 Distributed Coordination Function (DCF) Medium Access Control (MAC) protocol continues to suffer from throughput degradation when directly applied in multi-hop Wireless Mesh Network (WMN). The Request-to-Send/Clear-to-Send (RTS/ CTS) signaling partially solved hidden node problems however the exposed node problems remain unaddressed. These exposed nodes lead to throughput degradation especially when the transmission in multi-hop networks is considered. The major reason for this poor performance is the restricted nature of the IEEE 802.11 MAC, which does not allow exposed nodes to initiates its transmission for the entire duration of ongoing transmission. Moreover, since multi-hop communication such as wireless mesh network transfer the data packet via intermediate nodes, the amount of control handshakes that take place at each intermediate node significantly reduce the throughput. This project proposes a set of enhancement to the existing IEEE 802.11 DCF MAC by enabling concurrent transmission by the exposed nodes and reduces the amount of handshakes required at every hop until the data packet reaches its destination. Analytical models are developed for analytical study of MAC protocols operating in multi-hop mesh networks and simulated over quasi-static Rayleigh fading channel. The multi-hop network performances are evaluated in terms of throughput and delay. The protocol outperforms the existing IEEE DCF MAC with more than 260% increase in overall throughput of multi-hop WM

Switchable Absorptive Bandstop to Bandpass Filter using Stepped-Impedance Dual Mode Resonator

In this paper, a new switchable absorptive bandstop to bandpass filter using stepped-impedance dual mode resonator is proposed. This switchable filter provides two modes of operation which is absorptive bandstop and bandpass response. The first part of this paper presents a theoretical analysis of the absorptive bandstop filter using steppedimpedance dual mode resonator. The absorptive bandstop response can be achieved by connecting λ/4 length with the stepped-impedance dual mode resonator with correct diameter and position of via hole as an inductive element. The second part of this paper presents an investigation and design of the switchable absorptive bandstop to bandpass filter. PIN diodes are used as the switching element. The selectivity of the bandpass response can be improved by using extended via hole. The parametric studies together with the EM simulation of the new switchable absorptive bandstop to the dual mode bandpass filter is presented in this paper

Mode i stress intensity factors of slanted cracks

The solutions of stress intensity factors of slanted cracks in plain strain plate are hard to find in open literature. There are some previous solutions of stress intensity factors available, however they are not studied completed except for the case of plain stress. The slanted cracks are modelled numerically using ANSYS finite element program. There are ten slanted angles and seven relative crack depths are used and the plate containing cracks is assumed to fulfil the plain strain condition. The plate is then forced uni-axially the stress intensity factors are determined according to the displacement extrapolation method. Based on the numerical analysis, it is found that slanted angles have inverse effects on the behaviour of stress intensity factors. Increasing such angles capable to reduce the mode I stress intensity factors. On the other hand, it is also enhanced the capability of mode II stress intensity factors at the crack tip. Due to difficulty of determining stress intensity factors numerically, a regression technique is used to formulate mathematical expressions which are capable to predict the stress intensity factors in reasonable accuracies

Geological dimension of the cultural heritage: A case example of the Ajanta Caves (Maharashtra, India)

[Abstract]International development for the both geoconservation and geotourism requires attention to all kinds of (potential) geological heritage. The Ajanta Caves (western Maharashtra, India) is a famous cultural object consisting of 30 caves carved in the Deccan Traps and inscribed to the UNESCO list of the World Heritage Sites. Its examination permits to indicate four geological features, which are the artificial caves themselves (these mark geological activity of the man in the historical past), the end-Cretaceous flood basalts (these demonstrate the emplacement of Large Igneous Province and the relevant palaeoenvironmental catastrophe), the gorge of the Waghora River (this is peculiar landform resulted from the river erosion of hard rocks), and the rockfall hazard (this is an interesting engineering geological phenomenon linked to the caves construction/maintenance). Geological heritage value of these features is argued. Unfortunately, there is not any geotourism activity at the Ajanta Caves presently. The content analysis of the principal on-line resources (web pages) devoted to this cultural site reveals the absence of sufficient geological information that would 68 Gontareva, E.F et al. CAD. LAB. XEOL. LAXE 38 (2015) facilitate geotourism. Generally, judgements about the Ajanta Caves and the other similar sites in the geological dimension permit to consider the wide spectrum of the geological heritage. They also highlight some extra opportunities for geotourism, which can benefit by its development at cultural sites with thousands of visitors
