Embedded Phone Call Based Burglary Security Alert System

The importance of security in our society cannot be overemphasised, as it drives economic growth. This research reviewed the problems associated with embedded alarm systems together with other embedded security system like SMS based security system. In this paper, Embedded Phone Call Burglary Security Alert System was developed which calls the house owner on detection of an intruder, so that adequate security measures may be taken to catch the burglar. It is implemented to be used with any kind of mobile phones. Also, adequate security measures can be taken by the appropriate agencies to apprehend the intruder/burglar. The system was built using Atmega32 microcontroller, GSM/GPRS modem, infra-red sensor and proximity sensors and Embedded Basic/programming. The proximity sensor is placed to sense the door and window entrance while the infrared is placed to have line of sight communication in order to capture intrusion from the ceilings. SIM900 Module is a cellular protocol that interoperates with a Universal Asynchronous Receiver and Transmitter (UART) onboard communication protocol

BANKING QUEUE SYSTEM IN NIGERIA

Queuing in Nigerian bank is an approach that involves lining up of customers in bank hall in order to be served bybank personnel at each terminal (server). At any point in service time, customers usually move to the desk for oneenquiries or the other. This and other obstructions result to much delay in customers waiting time. It now becomesone of the challenges for banks, to be able to manage the time spent by customers in the banking hall to remaincompetitive. The aim of this research is to minimize waiting time in queue by proper queue management andthereby maximizing throughput. We developed a web based application that assigns each customer queue numberon arrival based on touching the screen and the queue number are stored electronically. First in First out QueueMethod is implemented in the design to achieve an orderly service delivery, also customer who have successfulgotten the queue number are attended to first based on FIFO-Queue Model already programmed, After asuccessfully daily operation in the bank, performance measure can be display. The proposed system whenimplemented will minimize the problems of congestion, and better service will be achieved. This research uncoveredthe applicability and extent of usage of queuing models in achieving customer satisfaction at the lowest cost.Keyword: Queue, Fifo, Bank, Customer, Operatio

Association between serum vitamin D status and uterine leiomyomas: a case-control study

Objective Uterine leiomyoma is a common gynecological condition that negatively affects women’s quality of life. Vitamin D plays an important role in tumor development and progression. However, clinical studies comparing serum vitamin D levels between women with and without uterine leiomyomas are limited and inconclusive. This study aimed to compare serum vitamin D levels in women with and without uterine leiomyomas. Methods This hospital-based case-control study included 150 women who visited a gynecological clinic. The cases included 75 women with uterine leiomyoma, whereas the controls included 75 age-and parity-matched participants without uterine leiomyoma. Serum vitamin D levels were measured in each participant and volumes of the uterine leiomyomas were determined using the water displacement method following myomectomy. The statistical significance was inferred at P<0.05. Results The mean serum vitamin D level was 15.26±4.96 ng/mL and 22.45±6.93 ng/mL for the case and control groups, respectively. The difference was statistically significant (t-value −7.302 and P<0.001). Within the fibroid group, nine (12.0%), 49 (65.33%), and 17 (22.67%) participants had vitamin D deficiency, insufficiency, and sufficiency, respectively; and in the control group, two (2.67%), 24 (45.33%), and 39 (52.0%) participants had vitamin D deficiency, insufficiency, and sufficiency, respectively. There was significant negative correlation between the fibroid volume and the serum vitamin D level (r=−0.591, P<0.001). Conclusion Women with uterine leiomyoma had lower vitamin D levels than women in the control group. Lower vitamin D levels were associated with larger fibroid masses. Therefore, vitamin D supplementation may reduce fibroid growth and development

Placenta retention in the cow: Report of three cases

Retention of placenta is one of the most common postpartum conditions in farm animals associated with infertility when not treated promptly and adequately. In this report, three different cases of placenta retention recently handled at Veterinary Teaching Hospital, Michael Okpara University of Agriculture, Umudike, Abia State, Nigeria are described. In the first case, the cow had a normal calving but the placenta was not expelled about 20 hours after calving. This was treated  successfully with oxytocin after oestrogen priming of the uterus. The placenta was expelled 6 hours after the oxytocin injection. The second cow had a dystocia with the foetal head stuck and hanging out of vulva for over 12 hours before veterinary consultation. Episiotomy was done to deliver the dead calf and was associated with placenta retention. The case was successfully treated by applying gentle traction on the little stump of the placenta hanging out of the vulva. The third case was  observed in a cattle market in which parturition was induced by stress of  transporting the cow over a long distance. A pendulous weight was hung on the little placenta stump hanging from the vulva. On the following morning, treatment could not be continued as the cow had been sold off. Conditions capable of causing stress should be avoided in pregnant animal. In conclusion, this report has shown that retention of placenta is a frequent clinical phenomenon in cattle and can be  successfully treated with gentle traction and oxytocin administration.Keywords: Cow, Fertility, Oestrogen, Oxytocin, Placenta, Tractio

Clinico-hysteroscopic analysis of severe intrauterine adhesions among Nigerian infertile women

Introduction: Severe intrauterine adhesions are difficult to manage and are associated with poor reproductive outcomes following treatment. The objective was to study the clinical presentation and hysteroscopic findings of severe intrauterine adhesions seen at hysteroscopy in two fertility/gynaecological endoscopy units in Nigeria.Methods: A prospective study of 19 out of 76 women managed for intrauterine adhesions in our units. Data were analyzed with STATA software, version 12.0 SE (Stata Corporation, TX, USA).Results: Severe intrauterine adhesion accounted for 19 (25.0%) of 76 cases of intrauterine adhesions managed during the period. This constituted 11.9% of 160 infertile women who had diagnostic hysteroscopies in our units over the study period. The mean duration of symptom was 4.2 years +/-3.2. Amenorrhea in association with infertility (68.4%) was the main presenting complaint. Secondary dysmenorrhea and cyclical abdominal pain were found in 10.8% and 31.6% of the women respectively. The main aetiological events were complicated caesarean section (42.1%) and abdominal myomectomy (26.3%). The adhesions were mainly dense (52.6%) and multiple (94.7%) with complete involvement of the uterine cavity in all the cases. Obliterative lesions were seen in 63.2% of the women.Conclusion: The main clinical presentation of severe IUA was amenorrhea and infertility while the major risk factors were complicated caesarean section and myomectomy. The adhesions were mainly multiple, dense, obliterative and complete.Keywords: Severe, intrauterine adhesions, hysteroscopy, hypomenorrhea, amenorrhea, Nigeri
