A Survey on Human Face Recognition Invariant to Illumination”,

ABSTRACT Human face recognition is one of the research areas in the current era of the research. It is one the widely used biometric technique for identification and verification of the human face. There are many challenges to face recognition which degrade the performance of the algorithm. The illumination variation problem is one of the well-known problems in face recognition in uncontrolled environment. In this paper an extensive and up-to-date survey of the existing techniques to address this problem is presented. Different authors have given so many techniques for illumination reduction from the face image but still some combined survey is missing so we have tried to fill that gaps in this paper. We have collected various preprocessing techniques suggested by different authors and shown their results in a tabular form. After preprocessing we can use any of the recognition method for face recognition. There are so many online face databases available so we can use any of them

Farmers’ Perception of the Effects of Climate Change and Coping Strategies in Three Agro-Ecological Zones of Nigeria

The study assessed farmers perception of the effects of climate change and coping strategies in three agro-ecological zones of Nigeria. Three agro-ecological zones namely Middle-Belt, North-Central and North–East were purposively selected and one LGA where NAERLS extension model village is located was purposively selected from each of the 3 agro-ecological zones. One village was randomly selected in addition to the NAERLS model village. Twenty five farmers were randomly selected from each village. One hundred and fifty (150) validated structured questionnaires were used to elicit information from respondents. Data were analysed using both descriptive and inferential statistics. Farmers were fully aware of the effect of climate change and possible coping strategies such as the need for agricultural insurance, planting of drought and flood tolerant varieties and reduction of water loss through practices such as mulching and rearing of heat tolerant livestock. General perception was that climate change increases the rate of sickness/infection, reduces family income and that frequency of flood and that drought has increased. Chi-square analysis indicated a positive and significant relationship between perception of climate change and agro-ecology (X2 =23.52;

Yield and Yield Attributes of Extra-early Maize (Zea Mays L.) as Affected by Rates of Npk Fertilizer Succeeding Chilli Pepper (Capsicum Frutescens) Supplied with Different Rates Sheep Manure

Field experiment was conducted in 2005 and 2006 to study response of extra-early maize variety (95TZEE-Y1) to rates of NPK (0, 40:20:20, 80:40:40 and 120:60:60 kg N:P2O5:K2O ha-1) and residual FYM (0, 5, 10 and 15 t ha-1 applied to chilli pepper the previous season) in the semi-arid zone of Nigeria. Randomized complete block design with three replicates was used. Higher values for soil physical and chemical properties were obtained in plots supplied with manure the previous season with soil from 2006 experiment more fertile than for the first year, hence produced 21% more grain yield. All the applied NPK rates in 2005 and except 40:20:20 ha1 in 2006 had resulted in early maize crop as compared to control. Husked and de-husked cob and 100-grain weights and grain yield/ha were higher at 120:60:60 kg NPK ha-1. Maize grown in plot supplied with 15 t FYM ha1 the previous year matured earlier. Cobs and 100-grain weights and grain yield were highest in plot supplied with 10 t FYM ha1. The 10t FYM ha-1 had 69% and 68% more grain yield than the control in 2005 and 2006, respectively. Highest maize yield was obtained at 120:60:60 kg NPK ha-1 or 10t FYM ha-1. All the parameters measured significantly and positively related to each other when the two years data were combined

Assessment of Climate Change Adaptive Strategies in Small Ruminant Production in Rural Nigeria

Animals are intrinsically dependent on the environment, and any fluctuations in weather and climate can affect them through water and land changes, such as desertification, feed and water availability. Climate change will not only impact the health and welfare of animals, but also the more than a billion people who depend on them. This study was therefore aimed at evaluating the adaptive measures used by rural farmers to alleviate the effect of climate change on small ruminant (sheep and goats) production in rural Nigeria. The target population for this study was all the small ruminant farmers in the five agro-ecological zones of Nigeria. A total of 300 respondents were interviewed using validated structured interview schedule. Data were analyzed using frequency counts, means and percentage. The result shows that most (71.9%) of the respondents were adults between 20 and 50 years of age. About 35% keep sheep and goats together while others keep either of the species. The most preferred management system is semi-extensive system (64%). Majority (93.2%) of small ruminant farmers in the rural Nigeria were aware of what climate change is all about and about 54% of them had observed changes in climage through personal experience.Majority of them had also observed and attributed changes to effect of climate change on their flock. Majority of them have also used various strategies to combat climate change. Traditional health care and irrigation of pasture during dry season were not effective adaptive strategies to combat climate change.There is need to educate the farmers more on the possible effect of climate change through the use of radio and other extension organizations (government and non-governmental) on the current situation and implication of climate change on themselves and their animals

Sri Lankan Medical Undergraduates Awareness of Nanotechnology and Its Risks

This study examines students’ understanding of the normative connections between key concepts of nanotechnology in nanomedicine and underlying biological principles that are critical for an in-depth understanding of its therapeutic application in medical field. A structured questionnaire was distributed among randomly selected undergraduates at the Faculty of Medicine and Allied Sciences, University of Rajarata, Sri Lanka. A total of 80 students participated in this study and completed written questionnaire on nanomedicine. The outcome of this study shows that there is a strong positive response on basic knowledge on nanoscale, but the undergraduates had an average knowledge on therapeutic application related to nanomedicine. Almost all students had a good knowledge on nanoscale but they lack knowledge of the relationship between nano and nanomedicine. Specifically, students were challenged to demonstrate an integrated understanding of the nanomedicine therapeutic application. Almost 58% of them were unable to give an example of it. Also some students struggled to explain it. Furthermore, in this study it was observed that there is a positive correlation in risk benefit section related to nanomedicine. Although the outcome is preliminary in nature, the results provide cause for concern over the status of nanotechnology education in Sri Lanka which needed to be uplifted
