Situs invertus totalis in a child with chronic sinusitis  [PDF]
Chinawa Josephat Maduabuchi, Ujunwa Fortune Amuche, Eze Chukwubuike Uzodinma
Open Journal of Pediatrics (OJPed) , 2013, DOI: 10.4236/ojped.2013.33041
Abstract:

Background: Total situs inversus, (also called situs transversus or oppositus) known as mirror image dextrocardia, is characterized by a heart on the right side of the midline while the liver is on the left side. Situs Inversus Totalis (SIT) is a congenital anomaly characterized by complete transposition of abdominal and thoracic organs. Patients with this anomaly usually lead a normal life. We report a fourteen-year old Nigerian who was found to have dextrocardia with situs inversus totalis while presenting for treatment for a different problem. Conclusion: Situs inversus totalis is a rare finding. This report underscores the need for routine screening of children so that such congenital anomalies can be identified and complications that follow it averted timely.


Increasing the Value of Agricultural Products in the Face of Global Economic Recessions: Anambra Experience
AN Eze
African Research Review , 2011,
Abstract: The Paper examined the increasing value of agricultural products in the face of global economic recession in Anambra State. The paper revealed that Anambra State is endowed with human and natural resources and if properly harnessed, can go a long way in arresting the food insecurity in the State and alleviate the poverty level of the poor masses. The study showed that yam, cassava, livestock and rice are the most common products produced in almost all the Local Government Area of the State. Although Anambra State is highly urbanized, its forest reserve covered 31897 hectares of land and the vast primary products can be transformed into secondary products, given the available and affordable technologies required. The paper revealed that in addition to N 150 million naira disbursed in 2007 and 2008 at an interest rate of 8.0%, the State Government has completed plans to disburse another N3.0 billion naira to small-scale businesses including farmers to boost their agricultural potentials. It was concluded that yield increasing technologies such as tractors, improved varieties of seeds, seedlings, livestock, agrochemicals and agro-machines should be highly subsidized by the state government to enable the resource poor farmers meet up with the yawning demands of improved products.
On-Farm Evaluation of the Use of Cassava Root Meal as a Partial Substitute for Maize in Broiler Diets in Anambra State
AN Eze
African Research Review , 2011,
Abstract: The paper determined the on-farm evaluation of the use of cassava root meal as a partial substitute for maize in broiler diets. The result shows that at the 70th day of the experiment, the different diets were adequate in promoting the healthy living and growth of the birds. The results also reveals that the final weight of the birds ranged from 2.23% to 2.78% and average weight gains, ranged from 1.19kg to 1.75kg. The result further indicates that the use of cassava as a substitute for maize in broiler diets has no significant influence on the live-weight of the birds. The result shows that treatment 3 is the cheapest in terms of cost of production (N2320.60), has the highest feed conversion efficiency and the lowest for one kg of broiler meat. The paper suggested for such trial to be carried out with higher percentage of cassava inclusion from day old to market weight. The use of garri in place of cassava flour to reduce its dustiness and improve storability is also suggested.

Journal of Geographic Information System (JGIS) , 2019, DOI: 10.4236/jgis.2019.112009
Abstract: Digital Elevation Models (DEMs) depict the configuration of the earth surface and are being applied in many areas in earth and environmental sciences. In this study, the accuracy of the Advanced Land Observing Satellite World 3D Digital Surface Model version 2.1 (ALOS W3D30), the Shuttle Radar Topography Mission Digital Elevation Model version 3.0 (SRTM30) and the Advanced Space borne Thermal Emission and Reflection Radiometer Global DEM version 2.0 (ASTER GDEM2) was statistically assessed using high accuracy GPS survey data. Root-Mean-Square errors of ~5.40 m, ~7.47 m and ~20.03 m were obtained for ALOS W3D30, SRTM30 and ASTER GDEM2 respectively. In further analyses, we discovered that ALOS W3D30 and SRTM30 were much more accurate in regions where the height intervals were within 201 m - 400 m and >801 m. ALOS W3D30 proved to be the most accurate DEM that best represents the topography of the earth’s surface and could be used for some earth and environmental applications in Nigeria. We recommend that this study should serve as a guide in the use of any of these DEMs for earth and environmental applications in Nigeria.
Refinement and Quantification of Terrain-Induced Effects on Global Gravity Data  [PDF]

Abstract: The geodetic and geophysical applications of Earth Gravity Field parameters computed from Global Geopotential Models (GGMs) are quite on the increase despite the inherent commission and omission errors of these models. In view of this, this study focuses on refining and quantifying terrain-induced effects on Bouguer gravity anomalies computed directly from a total of seven recent GGMs. In the study, the Residual Terrain Model (RTM) technique was used to estimate the residual terrain effects that were added to the GGM-computed Bouguer gravity anomalies at the sixty test points in Enugu State, Nigeria. The computed residual terrain effects range from -24.6 to 37.5 mgal while the percentage of the omission errors of the GGMs based on their Root-Mean-Square (RMS) differences ranges from 7.8% to 44.7%. It can be concluded that GGM-refined Bouguer gravity anomalies are better in accuracy than the unrefined GGM-computed Bouguer gravity anomalies and hence there is need for accurate height information in the development of GGMs. We, therefore, recommend that refined Bouguer gravity anomalies obtained from HUST-Grace2016s, EIGEN-6C4 and GECO that gave best improvement amongst the seven GGMs under consideration should be used to supplement the available terrestrial Bouguer anomalies for geodetic and geophysical applications within the study area.

Consumer Rights as Constitutional Rights-A Comparative Analysis of Some Selected Jurisdiction
AG Eze
Nnamdi Azikiwe University Journal of International Law and Jurisprudence , 2011,
Abstract: The greatest danger faced by consumers lies in the consumption of fake and adulterated goods. The consequence of consumption of fake and substandard goods is sometimes dangerous to human life. Despite this fact, violation of consumer rights which is the hallmark of consumer protection is still being considered in Nigeria as breaches of either contractual or tortious right. This study analyses from a global perspective the extent to which consumer rights have become entrenched in constitutions of some countries of the world. This study makes a case for the entrenchment of consumer rights as constitutional rights in Nigeria.
Fe KαLine in Hard X-ray Emitting Symbiotic Stars

Physics , 2013, DOI: 10.1093/mnras/stt1947
Abstract: The 6.4 keV iron emission line is typically created by irradiation of the neutral (or low ionized) iron by a hard X-ray source. Whereas the 6.7 and 7.0 keV emission lines are mainly produced by photoionization and collisional excitation in hot plasma, the 6.4 keV fluorescence line is typically a signature of either reflection from an accretion disk or absorption. We have surveyed the emission using a collection of Suzaku ob- servations of hard X-ray emitting symbiotic stars to better understand the geometry of these systems. We find that they do not seem to have a single geometry, and that while absorption-induced fluorescence leads to some emission in three of the hard X-ray emitting symbiotic stars (hSSs) in our study, CH Cyg, T CrB and RT Cru there are strong hints that significant 6.4 keV emission arises in the accretion disk irradiated by the hard X-rays from the boundary layer between the accretion disk and hot white dwarf in one of our sources, SS73 17. The 6.7 and 7.0 keV lines, however, are largely produced by collisional excitation in the vicinity of the compact white dwarf.
Morphometric Parameters of the Calabar River Basin: Implication for Hydrologic Processes
Eze Bassey Eze,Joel Efiong
Journal of Geography and Geology , 2010, DOI: 10.5539/jgg.v2n1p18
Abstract: The study examined the morphometric parameters of the Calabar River Basin with emphasis on its implication for hydrologic processes. Data for this study were obtained from topographic map which were subject to field confirmation. The result revealed that the basin area was 1 514km2. There were 223 streams with a total stream length of 516.34km. The textural dissection was considered to be low as drainage density, stream frequency and drainage intensity values were 0.34km-1, 0.15km-1 and 0.05 respectively. The basin was found to be strongly elongated with circularity ratio of 0.34 and elongation ratio of 0.64. The average bifurcation ratio was 2.83. The very low value of drainage intensity implies that drainage density and stream frequency have very little effect on the extent to which the surface has been lowered by agents of denudation. These low values of drainage density, stream frequency and drainage intensity also imply that surface runoff is not quickly removed from the basin, making it susceptible to flooding, gully erosion and landslides, particularly in the lower part of the basin. It is therefore recommended that human activities that could impact negatively on stream network in the basin should be discouraged.
Escherichia coli superoxide dismutase expression does not change in response to iron challenge during lag phase: Is the ferric uptake regulator to blame?  [PDF]
Robert L. Bertrand, Michael O. Eze
Advances in Enzyme Research (AER) , 2013, DOI: 10.4236/aer.2013.14014
Abstract: Intracellular iron levels and the expression of superoxide dismutase (SOD) and hydroperoxidase (HP) are regulated in Gram-negative bacteria by the iron(II)-activated ferric uptake regula- tor (Fur). We have previously observed that the expression of SOD in exponential phase Escherichia coli is dependent upon the redox state of iron in media, consistent with the ferrous specificity of Fur regulation (Bertrand et al., Med. Hypotheses 78: 130 - 133, 2012). Through the non-denaturing electrophoretic technique we have determined the Escherichia coli expression profiles of SOD and HP in response to iron challenge throughout lag, logarithmic, and stationary phases of replication. Lag phase SOD presented an unusual expression profile such that SOD expression was unresponsive to iron challenge, analogous to observations of mutant strains lacking Fur and of E. coli incubated in iron-deplete media. Challenging Escherichia coli with iron during logarithmic phase revealed that length of exposure to oxidants is unlikely to be the cause of SOD unresponsiveness in lag phase. HP activity was up-regulated two- or three-fold throughout all growth phases in response to iron challenge, but did not present redox- or growth phase-specific outcomes in a manner analogous to SOD. We hypothesize that low Fur levels during lag phase are responsible for unresponsive SOD.
