Quality of Garabia (A Nigerian Traditional Snack) From Four Varieties of Rice As Affected By the Addition of Cowpea
M.H. Badau,C. Ngozi,N. Danbaba
Advance Journal of Food Science and Technology , 2013,
Abstract: An experiment was conducted to evaluate the nutritional and sensory attributes of garabia a traditional cereal-based snack of Nigeria manufactured from flour obtained from broken fractions of milled four popular rice varieties in Nigeria as a strategy for the improvement of rice postharvest system for improved income and livelihood. The mean moisture, protein, fat, ash and carbohydrate contents of rice-cowpea blend garabia were 2.25, 11.87, 34.83, 2.04, and 49.00%, respectively and ranged between 1.88 to 2.47% for moisture, 10.72 to 12.86% for protein with FARO 52 blend having the highest and NERICA-L34 recording the lowest value. Calcium was found to be the most abundant mineral in rice garabia. The calculated metabolizable energy values of the blended rice garabia showed that the products are concentrated energy sources and compares favorably snacks from other sources. Consumer overall acceptability (liking) rating was higher than 6 (like slightly) based on hedonic ratings based on 9-point hedonic scales indicating that the product are well-liked by the consumers. It can then be concluded that addition of cowpea to rice flour for the production of garabia significantly improves nutritive value of the products with little or no pronounced effect on consumer acceptability.
Comparison of a Class of Rank-Score Tests in Two-Factor Designs
A Danbaba
Nigerian Journal of Basic and Applied Sciences , 2012,
Abstract: Rank score functions are known to be versatile and powerful techniques in factorial designs. Researchers have established the theoretical properties of these methods based on nonparametric hypotheses, but only scanty empirical results are available in the literature on these procedures. In this paper, four types of rank score functions Wilcoxon-scores, Mood-scores, normal-scores and expected normal- scores are studied in the context of two Vway factorial designs using asymptotic ó2 (Wald-Type) and modified Box- approximation (ANOVA-Type) tests. The empirical Type I error rate and power of these test statistics on the rank scores were determined using Monte Carlo simulation to investigate the robustness of the tests. The results show that there are problems of inflation in the Type I error rate using asymptotic ó2 test for all the rank score functions, especially for small sample sizes and distributions studied. The modified Box- approximation test was found to be robust for both validity and efficiency, especially for Wilcoxon, normal and expected normal score functions. It was concluded that the asymptotic ó2 test is non-robust for rank score functions in two-factor designs.

Abstract:
In 2016, the total estimated paddy production in Nigeria was 17.5 million metric tons (MMT) which is equivalent to 5.7 MMT milled rice. This is 1.3 MMT lower than the projected 7.0 MMT national consumption demands. This implies that Nigeria is progressing towards achieving self-sufficiency in rice if this data is compared with 3.5 MMT milled rice production in 2010. But about 10% - 30% or more of this increase does not reach the final consumers largely due to inefficient postharvest management practices. Huge postharvest grain loss (PHGL) and postharvest grain quality loss (PGQL) have been reported and significant efforts have been made towards reducing them and improving food security, but this is hampered by lack of simple, cost effective, adoptable and well-defined practical postharvest management practices and technologies. This situation has presented huge opportunity for investment and strategic interventions. From the point of harvest till rice reaches the consumers table, rice passes through wide range of unit operations which may have impact on the quantity and quality of the milled rice, these have made value chain actors adopt different practices to manage the process as it passes through the various unit operations. This paper examines the current rice post-harvest management technologies in Nigeria, with attention focusing on the current practices, constraints militating against the improvement of the rice postharvest system and opportunities it presents for improvement taking into account the main contribution of the research and development organizations in solving rice postharvest related challenges and lessons to be learned that will sharpen future direction for sustainable development.
HIV/AIDS AND RYMV INFECTION COMPLEX: IMPLICATION FOR NUTRITION AND SUSTAINABLE RICE PRODUCTION IN SUBSAHARAN AFRICA
Abo M. Emmanuel,Danbaba Nahemiah,Francis Nwilene
Academic Research International , 2012,
Abstract: In sub-Saharan Africa (SSA), especially, West Africa, rice is the single largest source of calories in the diet of low income groups. In 2003, rice provided daily 342 kcal per capita compared to 277 kcal from millet, 275 kcal from sorghum, 247 from cassava and 216 kcalfrom maize. Agriculture, nutrition and human health are interlinked in many ways. Human Immunodeficiency Virus (HIV) causes AIDS disease in human, while rice yellow mottle virus (RYMV) is a devastating disease in rice for which farmers in French speaking countries of West Africa ‘Sida du riz’ meaning AIDS of rice. HIV/AIDS is a world wide pandemic, with 70% infected person living in SSA, while RYMV is restricted to African rice fields. The diseases are both devastating and infectious and are of economic significance to nutrition and rice productivity. This paper highlight the nature of the viruses, effects, management practices and the implication of the combined effects on nutrition and rice productivity in SSA and its consequences on smallholder, resource poor rice farming families.

Open Access Library Journal (OALib Journal) , 2018, DOI: 10.4236/oalib.1104538
Abstract:
Prediction of a child HIV status poses real challenges in medical research. Even though there are different statistical techniques and machine learning algorithms that have been used to predict models like HIV for the clinical data with binary outcome variables, yet neural network techniques are major participants for prediction purposes. HIV is the primary cause of mortality among women of reproductive age globally and is a key contributor to maternal, infant and child morbidity and mortality. In this paper, resilient back propagation algorithm is used for training the Neural Network and Multilayer Feed forward network to predict the mother to child transmission of HIV status.

N. N. Barsoum
Journal of Electromagnetic Analysis and Applications (JEMAA) , 2010, DOI: 10.4236/jemaa.2010.22012
Abstract: Many single and three-phase converters are well developed, and covered up in most of electric markets. It is used in many applications in power systems and machine drives. However, an exact definite output signal from the dc side still not recognized. The waveforms of output voltage and current demonstrate an imperfect dc signal and constitute losses, harmonic distortion, low power factor, and observed some ripples. An approximately perfect rectifier bridge is the aim of this research. Perhaps it gives the ability to identify the parameters of the converter to obtain, as much as possible, a perfect dc signal with less ripple, high power factor and high efficiency. Design is implemented by simulation on Power Simulator PSIM, and practically, a series regulator LM723 is applied to provide regulating output voltage. Comparisons of both simulation and hardware results are made to observe differences and similarities.

N. Pankratova, N. Nedashkovskaya
Intelligent Control and Automation (ICA) , 2013, DOI: 10.4236/ica.2013.41011
Abstract:

The paper provides mathematical analysis of sensitivity of different combination rules in the DS/AHP method when an alternative is added to the set of decision alternatives while solving foresight problems. Different cases of rank reversals are defined and two sets of conditions for these cases using the method DS/AHP are considered. Rank reversals are illustrated when the DS/AHP method is used to solve practical problem of critical technologies of energy conservation and power efficiency evaluation in Ukraine. It is shown that the DS/AHP method is not sensitive to exclusion (or addition) of an irrelevant decision alternative from (or to) the set of decision alternatives.

Computation of the Genetic Code: Full Version  [PDF]
N. N. Kozlov
Journal of Computer and Communications (JCC) , 2017, DOI: 10.4236/jcc.2017.510008
Abstract: One of the problems in the development of mathematical theory of the genetic code (summary is presented in [1], the detailed—to [2]) is the problem of the calculation of the genetic code. Similar problem in the world is unknown and could be delivered only in the 21st century. One approach to solving this problem is devoted to this work. For the first time a detailed description of the method of calculation of the genetic code was provided, the idea of which was first published earlier [3]), and the choice of one of the most important sets for the calculation was based on an article [4]. Such a set of amino acid corresponds to a complete set of representation of the plurality of overlapping triple gene belonging to the same DNA strand. A separate issue was the initial point, triggering an iterative search process all codes submitted by the initial data. Mathematical analysis has shown that the said set contains some ambiguities, which have been founded because of our proposed compressed representation of the set. As a result, the developed method of calculation was reduced to two main stages of research, where at the first stage only single-valued domains were used in the calculations. The proposed approach made it possible to significantly reduce the amount of computation at each step in this complex discrete structure.
The Study of the Secrets of the Genetic Code  [PDF]
N. N Kozlov
Journal of Computer and Communications (JCC) , 2018, DOI: 10.4236/jcc.2018.67007
Abstract: The disclosure of many secrets of the genetic code was facilitated by the fact that it was carried out on the basis of mathematical analysis of experimental data: the diversity of genes, their structures and genetic codes. New properties of the genetic code are presented and its most important integral characteristics are established. Two groups of such characteristics were distinguished. The first group refers to the integral characteristics for the areas of DNA, where genes are broken down in pairs and all 5 cases of overlap, allowed by the structure of DNA, were investigated. The second group of characteristics refers to the most extended areas of DNA in which there is no genetic overlap. The interrelation of the established integral characteristics in these groups is shown. As a result, a number of previously unknown effects were discovered. It was possible to establish two functions in which all the over-understood codons in mitochondrial genetic codes (human and other organizations) participate, as well as a significant difference in the integral characteristics of such codes compared to the standard code. Other properties of the structure of the genetic code following from the obtained results are also established. The obtained results allowed us to set and solve one of the new breakthrough problems—the calculation of the genetic code. The full version of the solution to this problem was published in this journal in August 2017.
