An Overview of Smart Sensor Technology

A wireless sensor network (WSN) consists of spatially distributed autonomous sensors to cooperatively monitor physical or environmental conditions, such as temperature, sound, vibration, pressure, motion or pollutants. The development of wireless sensor networks was motivated by military applications such as battlefield surveillance. They are now used in many industrial and civilian application areas, including industrial process monitoring and control, machine health monitoring, environment and habitat monitoring, healthcare applications, home automation, and traffic control

USING THE CONCEPT OF A MAC SCHEDULING ALGORITHM FOR WIMAX NETWORKING ARCHITECTURE

Wimax is wireless digital communication system which is intended for wireless Metropolitan area networks. Wimax standsfor worldwide interoperability for microwave access. Wimax Technology enables ubiquitous delivery of wireless broadbandservice for fixed and or mobile users. An IEEE 802.16 wireless system can provide broadband wireless access to subscriberstations and operate in mesh mode. The communication between a subscriber station and a base station can pass through oneor more intermediate subscriber stations. The IEEE 802.16 standard provides a centralized scheduling mechanism thatsupports contention-free and resource-guarantee transmission services in mesh mode. This paper show how MAC schedulingarchitecture is emphasized for IEEE 802.16 standards.Keywords: MAC, QoS class scheduling, IEEE 802.16, WiMax, Network

Determinants of maternal healthcare services utilization in selected communities in Edo Central Senatorial District Nigeria

Background: Throughout history, society has always employed several means to promote maternal healthcare services to save pregnant women and their unborn babies from expected or unexpected dangers during pregnancy, birth and after birth. This study investigated the determinants of maternal health care services utilization in selected communities. Methods: A descriptive cross-sectional survey design was adopted for this study using a questionnaire as a quantitative tool. The population of the study comprised women of reproductive age group (15-49) Edo Central Senatorial District, Edo State Nigeria. A multi-stage sampling technique was used to select 561 study participants from the target population. A total of 561 copies of the questionnaire were administered but 490 of them were retrieved and found to meet criteria for analysis. Data was analyzed using SPSS version 25 and computed for descriptive statistics- frequency with percentage counts, mean and standard deviations. Additionally, inferential statistics chi-square used to test the stated hypotheses. Results: The finding showed that the women’s mean age of 28±5.37. Residential location of the participants did not significantly influence their utilization of maternal healthcare services. Educational qualifications, were found to influence the utilization of maternal healthcare services than those of lower educational levels (p<0.05). In addition, 364 (74.2%) respondents agree that free or low cost of maternal health services would prompt and promote regular visits to clinic. Conclusions: It is recommended that the government should provide freer or low-cost

Modifications hémorheologiques chez les cancéreuses

Several Studies have indicated the existence of thrombo-embolic complications in cancer patients and that this could be associated with changes in heamorheological parameters. Packed cell volume (PCV), heamoglobin (Hb), relative plasma viscosity (RPV) and plasma Fibrinogen concentration (PFC) were measured in 50 healthy control women, 50 age-matched women with breast cancer, and 10 women with histophathologically proven benign breast tumour. There were significant differences between the controls and breast cancer patients in all the parameters measured (p<0.05). However, patients with cancer have significantly higher RPV and PFC (p<0.001) respectively than controls. There was significant mean difference between pre and post mastectomy in fibrinogen concentration (p<0.05) and this was observed over the 5-week study period. Since increased fibrinogen may give rise to increase fibrin formation which has been asserted as an independent cardiovascular risk factor for thromb-oembolic complications, African patients with breast cancer may well be predisposed to thrombotic complications during illness. The rheological assessment may offer valuable benefit for the management and early diagnosis of breast cancer in African women.Beaucoup d&apos;études ont montré l&apos;existence des complications thrombe-embolique chez les cancéreuses et qu&apos;on peut lier ceci aux modifications dans les paramètres hémorheologiques. Le volume globulaire concentré (VGC), l&apos;hémoglobine (Hb), la viscosité du plasma relatif (VPR) et la concentration du fribinogène du plasma (CFP) ont été mesurés chez 50 femmes en bonne santé comme femmes témoin, 50 femmes cancéreuses qui ont été appariées selon l&apos;âge et 10 femmes qui souffraient de la tumeur du sein bénigne qui a été prouvée histopathologiquement. Il y avait des différences importantes entre les témoins et les patientes cancéreuses dans tous les paramètres mesurés (p < 0,05). Toutefois, les patientes cancéreuses ont une VPR considérablement plus élevé et la CFP (p < 0,001) respectivement que les témoins. Il y a une différence moyenne importante entre la pré et la post mastéctomie dans la concentration du fribinogène (p < 0,05) et ceci a été observé au cours des cinq semaines que l&apos;étude a duré. Puisque l&apos;augmentation du fibrinogène peut aboutir a l&apos;augmentation de la formation de la fibrine qui a été acceptée comme un facteur indépendant de risque cardiovasculaire pour des complications thrombe-emboliques. Les patientes cancéreuses africaines pourraient bien être prédisposées à des complications thrombotiques pendant la maladie. L&apos;évaluation rhéologique peut donner des avantages valables pour le traitement et le diagnostique anticipé du cancer du sein chez les femmes africaines

Haemorheological Changes in African Breast Cancer Patients

Effect Of Pulmonary Tuberculosis On Haemostatic Properties Of Blood

A total of 100 subjects were used in this study consisted of 40 known pulmonary tuberculosis (PTB) (17 male and 23 female) patients attending the out-patient clinic at the University of Benin Teaching Hospital and Central Hospital, Benin City with 10 newly diagnosed PTB patients, as well as fifty apparently healthy (17 male and 23 female) individuals from the Hospital community as controls. Plasma fibrinogen concentration (PFC), factor VII (F-VIIc) and factor VIII (F-VIIIc) clotting activities were estimated using standard methods. Plasma fibrinogen levels, in pulmonary tuberculosis patients were significantly higher (P < 0.05) while F VII and F VIII were significantly lower (

Efect of tubercle bacilli on plasma fibrinogen and fibrinolytic activi

Background: In the last decade an increase in the incidence of tuberculosis has been observed, due in part to the growing number of AIDS. The tubercle bacilli are thought is to have various effects on the properties of blood. Aim of Study: To determine the effect of tubercle bacilli on plasma fibrinogen and fibrinolytic activities in patients with tuberculosis. Patients and Methods: A total of 100 subjects, 40 pulmonary tuberculosis (PTB) patients (18 males and 22 female age range 20 – 40 years) microbiologically diagnosed attending the out patient clinic was studied. The parameters studied include plasma fibrinogen and euglobulin lysis time.Results: Plasma fibrinogen (PF) and euglobulin lysis time (ELT) was significantly higher (
