SOIL EROSION HAZARD ASSESSMENT USING SLEMSA MODEL IN OUTSKETCH PARTS OF KANO METROPOLIS

Abstract: 

The study was carried out to assess soil erosion hazard in outsketch of Kano metropolis, which is located between Latitude 11o59' and 12 o 02' N, Longitude 8o33' and 8o40'E. The Soil Loss Estimation Model for Southern Africa (SLEMSA), developed for conditions in Zimbabwe, was evaluated and used to determine a soil erosion hazard in outsketch of Kano metropolis; parameters were assessed with a view to model soil loss in outsketch of Kano Nigeria. The computed mean values of soil loss inform of erosion hazard unit (Ehu) for the study area is 188.02(Ehu). These value varied between 106.85542 (Ehu) in Tsamiyar Matasa – Gunduwawa to 313.74376 (Ehu) for the North Eastern Bypass. The estimated erosion hazard unit was higher in Northern Eastern Bypass, followed by Rimin Kebe with 143.45634 (Ehu) while Tsamiyar Matasa records the least soil loss between the sites. K value is responsible for high soil loss in Northern Eastern Bypass and low in Tsamiyar Matasa, while in Rimin Kebe the combination of all factors are the yardstick for high soil loss in essence no single factor seemed more important than the other factors in affecting the estimate soil loss values. The SLEMSA sub-models of cover, soil loss, and topography were computed from energy interception, rainfall energy, and soil erodibility, and slope length and steepness, respectively. Sensitivity analyses of the SLEMSA model revealed that rainfall energy and slope steepness have the greatest influence for the occurrence of erosion in the study area. The effect of the sensitivity indices of the five parameters in this research is rated as E>F>S>L>i in accordance with their relative importance for the occurrence of erosion. It is recommended that deep rooted trees that could help considerably in the binding of soil colloids against detachment should be planted. However, SLEMSA does not estimate rill or gully erosion. Therefore another method should be used to capture the gully erosion hazards for this area.

AN ASSESSMENT OF WIDOWHOOD AND ORPHANCY IN THE CONTEMPORARY HAUSA CULTURE IN KANO METROPOLIS, KANO NIGERIA

Abstract: 

This paper assesses the treatment of the family of deceases by the society and how it impacted on the wellbeing of the affected persons. It is a cross sectional survey research utilizing both quantitative and qualitative data through the identification of income, expenses, choices and decision in response to their predicaments. Structured interview and questionnaire are designed to capture the responses from widows, orphans and their neighbours/relative. Snowballing is adopted while sampling the respondents especially the people who are related to the orphans and widows. Simple descriptive statistics are used in describing the tally of some observed variables. Chi-square test was used to test the observed behaviors between widows and orphans. The findings revealed an amazing scenario where 80% of the widow lamented bitter experiences after the death of their husbands. Majority of the orphans suffers various problems in their upbringing including feeding and other necessities of life like clothes, shelter and schooling. Economic hardship, poverty and westernization change Hausa-polygamous culture which in turn made the widows at disadvantage of getting another husbands. The study discovered that female orphanage is more debilitating than their males’ counterpart. Majority are push into Hawking and other low-level livelihood options that affect their honour and decency at times injuring their health womanhood. The paper recommend with emphases that Government should revamp the welfare services to take care of widows and orphans through monthly allowances, free education and health care in order to protect and prevent them from evil-minds whom in the name of assisting, end of jeopardizing their future

EFFECT OF POLYPHENOL OXIDASE ON BROWNING OF APPLE AND GARDEN EGG

Abstract: 

Browning is a biochemical process that occur in fruits, it affects the quality of fruits and their products. This led to a concern by the food and beverage industry due to clouding and other undesirable effects that affect consumer acceptability. The enzyme polyphenol oxidase (PPO) is implicated in browning reaction. It oxidises O-diphenols to O-quinones, a process that leads to browning reactions in wounded fruits, vegetables and plants including apple and garden egg. Inhibition studies of polyphenol oxidase from apple (Malus domestica) and garden egg (Solanium aethiopicum) extracts was performed. Higher protein concentration (5.2mg/ml) was recovered from apple compared to 3.81mg/ml from garden egg, while the enzyme (PPO) activity and specific activities were higher in garden egg extract compared to apple. Browning of the fruit was rapid at pH 7.0 for apple as compared to pH 6.0 for the same effect in garden egg. The optimum temperature for the two fruits was discovered to be 25ºC. Inhibitors such as EDTA, ascorbic acid and metabisulphite could potentially be used to control enzymatic browning. Metabisulphite was found to be the most effective inhibitor against PPOs extracted from apple and garden egg. Similarly, processing of the fruits under acidic condition and at high temperature may inhibit enzymatic browning.

IDENTIFYING OBSTACLES TO KNOWLEDGE SHARING IN AN ORGANIZATION

Abstract: 

This study investigated possible causes of resistance or support by knowledge workers to sharing of knowledge within an organization. The problem addressed was that existing knowledge was not being effectively disseminated throughout the organization, resulting in lost productivity and opportunity as a result of failure to exploit available knowledge. Leaders of organizations and businesses can use the findings of this study to develop new processes and procedures for overcoming resistance to knowledge sharing, which might translate to increased innovation, productivity and competitive advantage. This study demonstrated that there were a myriad of barriers to knowledge sharing, these included but not limited to individual knowledge sharing, organizational knowledge sharing, technological knowledge sharing as well as cultural barriers. In doing so it confirmed prior research, as discussed in this paper. The research also uncovered a relationship between willingness to share knowledge and effective knowledge sharing, distributing the discovered barriers between each of these factors

SOCIAL MEDIA: AN INDISPENSABLE TOOL FOR ENHANCING PUBLIC SAFETY AND SECURITY

Abstract: 

The advancement in mobile technology has increased the usage of social media tremendously. Social media has opened up ways for people to easily interact with one another. At the same time it has open up ways for cybercrime and other actions that are threat to national security to be committed. Through social media, how can National Security be threatened? How can the security and safety of the citizens be enhanced? In this paper, we addressed these fundamental questions. Answers to these questions justify why social media is indispensable in the hand of security agents who are saddled with the responsibilities of protecting lives and properties of the public. In this paper our aim is to make it clear particularly to security agents and national security policy makers that social media is indispensable. That is, it should not be ignored considering the security threats it poses and its potentiality of being a tool that can be used by security agents to counter national security threats and safeguard the public.

Seasonal Ground water Configuration Maps showing Water level in Kano Metropolis, Nigeria.

Abstract: 

The paper presents the peak of dry and rainy season’s ground water configuration maps, so as to show the seasonal water level fluctuations in the study area. It involves measurement of wells elevations, static water levels from hand dugged wells at peaks of dry and rainy seasons and their elevations. The groundwater levels at peak of dry season in the area during the course of the study range from 3.20 to 19.00 mbgl (meter below ground level) with an average of 8.09mbgl. The maximum water levels elevation during the dry season was 500 masl (meter above sea level), minimum of 425.6 masl and average of 467.38 masl. While the water level measurement at peak of rainy season range from 0.50 to 12.0 mbgl. The maximum water level elevation was 508 masl, minimum of 444.60 masl and average of 479.04 masl. The differences in the groundwater levels for both peaks of dry and rainy seasons could be related to the variations in elevation, quantity of recharge, hydraulic properties, and other hydrogeologic conditions of the superficial aquifers in the study area. Information on the depth to water level has various uses, such as in borehole drilling, geotechnical investigations (for dams, roads, buildings etc), and in determining the direction of groundwater flow, which can be used for monitoring and identifying possible groundwater contamination

LINEAMENT ANALYSIS FOR ANKA SHEET 52, NE ZAMFARA STATE, NORTH WESTERN NIGERIA

Abstract: 

Remote sensing data (DEM) was used to study and analyze lineaments within Anka sheet 52 NE. Eight Shaded relief images were created by varying the solar Azimuth (0°, 45°, 90°, 135°, 180°, 2250, 2700, 3150). A solar elevation of 30o and an ambient light setting of 0.2 was chosen to ensure good contrast. Combination of shaded relief images 0°, 45°, 90°,135° and 180°, 225°, 270°, 315°was done to produce two combine shaded relief images. Automatic extraction of lineaments from these combine shaded relief images was carried out followed by buffering of lineaments to ensure continuity. Buffering of lineaments was followed by reclassification and combination of two reclassified image to generate a level of coincidence image. Reclassification of level of coincidence image was carried out followed by manual digitization of lineaments. Analysing these lineaments, it was observed that lineaments generated from combination of shaded relief images (0°,45°,90°,135°), had a dominant NW-SE direction. 52 lineaments were extracted from these images having a maximum length of 13701.2 m, minimum length off 2293 m. Lineaments extracted from combine shaded relief image (180°,225°,270°,315°) had a dominant N-S direction. A total of 47 lineaments were extracted and lineaments have a maximum length of 4346.093 m, and a minimum length of 2324.74 m. 90 lineaments were digitized from the final lineament map. A maximum length 8300.71m, a minimum length of 993.451 was recorded. A dominant N-S and NW-SE dominant directions was observed to be the dominant directions from the final lineament map. From this study it was observed that most streams within the study area are controlled by the lineaments. Also, the dominant N-S and NW-SE directions for lineaments can be related to Pan African orogeny.

Assessment of Naturally occurring Radioactive Materials (Norm) Along Jakara Waste Water Canal, Kano, Kano State, Nigeria

Abstract: 

This study is an assessment of the radioactivity level along the Jakara waste water canal. Five soil samples from different points along the canal were analysed using the Gamma Spectrometry with Sodium Iodide detector (Model Name: Canberra, Model Number: 727, Serial Number: 11914167). The results obtained for the Naturally Occurring Radioactive Materials (NORM) show that the activity concentration for 40K ranges from 242.61 Bq/Kg to 548.67 Bq/Kg and its calculated average value being 347.71 Bq/Kg. Values for 226Ra activity concentration ranges from 18.31 Bq/Kg to 38.58 Bq/Kg and having an average value of 24.47 Bq/Kg, while that of 232Th ranges from 34.77 Bq/Kg to 84.95 Bq/Kg with an average value of 47.85 Bq/Kg. Hence, this NORM result reveals that the activity concentration of 40K and 232Th near the abattoir, as well as 226Ra near Jakara police station are all higher than the world wide average. The calculated absorbed dose rate, ranging from77.23 nGyh-1 to 141 nGyh-1, at all the sample locations as well as the gamma index at the abattoir were found to be higher than the acceptable limit for the general public whereas the calculated annual effective dose equivalent, radium equivalent activity, the external and internal hazard indices, and also the alpha indices at all the sample sites plus the gamma indices at the rest locations apart from the abattoir, are all found to be lower in values than the specified limit.
