In this paper we devise a general model in determining several salient parameters that have an effect on the 24 GHz radar antenna. This method is also applicable to several antenna design areas such as the satellite communication in the Ku band and C-band but our focus is mainly on the 24 GHz and 77GHz radar

Acute appendicitis due to metastasis of prostatic carcinoma is very rare, and only five cases of metastasis of prostatic carcinoma are described in the literature. We report the case of a 73-year-old man with a history of an adenocarcinoma of the prostate with multiple bone metastases. The patient was admitted to the emergency department with symptoms and signs of an acute appendicitis which was confirmed by computed tomography (CT). Laparoscopic surgical exploration was performed, affirming an acute appendicitis with a suspicious lesion in the appendix base. Due to the location of the lesion, an ileocecectomy was performed. Histopathological and immunohistochemical examinations of the specimen showed an extrinsic infiltration of the appendix by adenocarcinoma metastasis expressing the prostate-specific antigen (PSA). These results confirmed an acute appendicitis caused by metastasis of prostatic adenocarcinoma.

Background and aims: The twisted gastric tube after an esophagectomy can be resolved with a minimally invasive treatment avoiding a reoperation. Methods: A 63 year old woman with tumor in the middle third of esophagus was operated on with esophagectomy and esophagogastric anastomosis in the neck. After 19days, she presented a funtional gastric tube estenosis secondary to rotation of the gastric tube. Results: A biodegradable stent was placed endoscopically and with interventional radiologist from the second portion of the duodenum to the prestenotic area of the gastric tube, fixed with clips. Conslusions: The biodegradable stent placement can be a possibility when a gastric tube volvulus occurs, avoiding a high risk reoperation.

Introduction: Embolization of the gastric and splenic artery is performed to improve blood flow to the constructed gastric tube during esophagectomy and thus reduce the rate of anastomotic leaks for this type of surgery. Patients and Methods: This is a retrospective, comparative study conducted from 2003 to 2013 of 32 patients undergoing preoperative embolization versus 102 patients not undergoing embolization to assess the impact of this technique on the rate of anastomotic leakage. The variables considered were age, gender, comorbidities, preoperative histopathology, location of the tumor, type of neoadjuvant therapy (if appropriate), type of surgery and type of anastomosis. Results: Patients had similar epidemiological and pathologic characteristics, except for the neoadjuvant treatment received. Of the 32 patients having embolization, 28 (87.5%) received chemoradiotherapy preoperatively, whereas only 52 of the 102 (50%) patients not having embolization received this therapy (p=0.0001). Of the 32 patients undergoing embolization, 14 (43.75%) developped an anastomotic leak versus 33 (32.35%) of the 102 patients not having embolization. No statistically significant differences were observed (p=0.289). Conclusions: Although ischemic conditioning of the constructed gastric tube by embolization of the left gastric artery and splenic artery prior to esophagectomy is a safe approach unrelated with morbidity, we could not demonstrate that it reduces the rate of anastomotic leaks.

In the atmospheric boundary layer there are horizontal pressure gradient and Coriolis force to the velocity distribution signify that, the horizontal component of the velocity in the boundary layer turns left (right) with increasing height in the Southern (Northern) Hemisphere, downward (upward) motion occurs on the windward (lee) side of the mountain, and downward (upward) motion also occurs on the slope to the right (left) of the geostrophic wind in the Northern Hemisphere, whereas in the Southern Hemisphere upward (downward) motion occurs on the slope to the left (right) of the geostrophic wind. Using Navier-Stokes equations for threedimensional stationary flows, hydrostatic and continuity equations, the effects of first order reactant of Coriolis force and dust particles for small Reynolds number in the atmospheric boundary layer over territory is obtained.

Household size is one of the determinants of socioeconomic development of any country. It is the total number of people living in a house, sharing certain things in common and may contain more than a family: it includes the fathers, mothers, children and other dependents that live under the same roof and having certain things in common. Household size varies in size in space as a result of diverse reasons. In the light of this, the present study is conceived, in order to establish the relationship between household size and health status of rural areas of Federal Capital Territory, Nigeria. The study involved 172 household heads across the six area councils of the study area. Random sampling technique was adopted to obtain all the relevant data. In all, in-depthinterviews (IDI), Focus Group Discussions (FGDs) were conducted and questionnaires were also administered in the randomly selected settlements of the wards on the subject matter. Data from all these sources were subjected to correlation analysis. The study concludes that, there is high proportion of household size in the study area with its attendance effects on the health status of the rural populace. In the face of this finding, the study recommends manageable household size as one of the conditions for healthy living upon which economic growth can evolve. This can be achieved through adequate family education.

The comparative effect of Diazepam and magnesium sulphate on motor coordination and seizures in mice induced with 4-Aminopyridine (4-AP) was studied. Thirty six (36) Swiss white male and female mice were randomly assigned into three (3) groups of six (6) animals each for seizure and beam walking test. Group one animals served as control group and were given normal saline intreperitoneally. Group two animals were given Magnesium sulphate (M.S) (4.5mg/kg) intraperitoneally. Group three (DZP) animals receieved Diazepam (DZP) (2mg/kg) intraperitoneally for the beam walking test. While for the seizure tests, Group one (4-AP) served as control and were given 4-Aminopyridine (4-AP) (13.3mg/kg) only, intraperitoneally. Group two (M.S) animals were given 4-Aminopyridine and Magnesium sulphate (M.S) intraperitoneally 15 minutes before inducing epilepsy with 4-AP. Group three (DZP) animals received 4-Aminopyridine and Diazepam intraperitoneally 15 minutes before inducing epilepsy with 4-AP. Anti-epileptic effect was assessed by scoring the onset of both tonic and clonic seizures.

The Nigerian state is not alien to electoral violence which can be traced as far back as the pre independence elections. Contestants in Nigeria can go to any length to rig and win elections even if it means to break the states monopoly of violence to deploy terror to win elections. At the just concluded 2015 general elections in Nigeria, the South South part of Nigeria witnessed different levels of mayhem and the destruction of lives and property. On the other hand the Northern and South Western states witnessed minimal electoral violence unlike previous years where violence was more in the North. To this end it is the aim of this paper to highlight how electoral violence was reduced during the 2015 general elections. This paper adopted the use of secondary data in the analysis of the research. However this paper concluded that the electorates in the Northern part of Nigeria and the South West aligned to the All Progressives Congress political party (APC) the opposition party which eased tensions but in the South South violence broke out as a result of an attempt by the opposition party to unseat the ruling party Peoples Democratic Party (PDP). This paper recommends that continuous voter education should be increased in order to educate people on the ills of electoral violence. Also stiffer penalties should be handed down on the agents and accessories of electoral violence so as to deter others from deploying violence in future elections in Nigeria.

That e-governance is the concept and structure of the system and the functions and activities of all activities and processes in e-business on the one hand the level of e-government and business on the other. Because the government sector as a significant proportion of the total economic sectors in most countries of the world, and the fact that dealing with the public sector is not limited to the class and not others, but prevail all citizens and residents, institutions and others, and the fact that this multi-dealing in quality, methods and how it is done and models for different procedures and steps implemented and locations between the corridors of government departments, the concept of e-government came as an ideal way for the government to enable them to take care of the interests of the public from individuals and institutions electronically using cutting-edge technology without the need for the applicant to move between government departments.

Network is a technology used to connect computers and devices together. They allow people the ability to move easily and stay in touch while roaming the Internet in the coverage area. This increases efficiency by allowing data entry and access to the site. Comparing wireless networks wired networks in terms of cost, we find that wired networks are more expensive due to the cost of the network connections of electricity and running and add computers and change their positions to suit the network supply. As a result, the use of widespread wireless networks. But there are security gaps in these networks may cause problems for users Security holes intended problem or weakness in the wireless network system may make it easier for hackers to penetrate and steal sensitive data and causing material losses to individuals and companies.
