Home Based Factors as Determinants of Secondary School Students Dropouts in Nakuru County, Kenya

The purpose of this study was to investigate the determinants of secondary school dropout in Nakuru County, Kenya. This study investigated; if home-based factors determine secondary school dropouts. The study employed the causal comparative design . The researcher used stratified random sampling technique to obtain 180 Form three students. The data from the field was mainly collected using questionnaires, interview schedules and document analysis. The data was analyzed mainly through descriptive methods such as tabulation of frequencies, mean and percentages. The study was guided by Robensons’ and Hoghliems’ Expectancy-Valence theory which states that the decision regarding participation and dropping out among students is functions of cognitive, social and environmental variables. The finding of this study revealed that the governments’ objectives of retaining all students in secondary school have not been met in the study area. The study established that an average 10.2 percent of students dropped out of secondary schools in the study area. This was against the global commitment of attaining Education for All (EFA) as agreed in the Jomtien Conference in 1990 and Dakar, Senegal in 2000. The study recommended that, there is need to efficiently and effectively run the Constituency Development Fund (C.D.F) and bursary schemes operated by the Ministry of Education (MEO). There is need also for the government of Kenya and Non Governmental Organizations (N.G.O’s) to assist parents to start up small businesses through micro financing. Further, the government of Kenya needs to spell out clearly the guidelines on how teenage mothers would be admitted back to school as the 1994 policy was not clear on this. The finding would be useful to policy makers, parents, students and the community at large. Keywords: Home-Based Factors, Determinant, Drop Out, Students, Questionnaire.
Tunable narrowband antireflection optical filter with a metasurface

A narrowband tunable antireflection optical filter is proposed and numerically studied. The structure is a metasurface based on plasmonic nanoparticles on an electro-optic film in a three-layer configuration of metal-dielectric-metal (MDM) in the visible near-infrared range. By tuning the voltage and thus tuning the refractive index of the dielectric LiNbO3, one can shift the wavelength of minimum reflection as desired. The parameters of gold nanoparticles and other elements used for the filter design and refractive index of the dielectric are obtained by the finite-element method (FEM). An analytical theory is presented to explain the FEM simulation results, and they agree well with each other. It is found that the frequency of the plasmonic resonance wave on the metasurface should be equal to that of the Fabry–Perot resonator formed by the MDM to have a good filtering property. Theoretical spectra obtained by FEM simulation show that the structure has extensive potential for the design of tunable narrow-band filters for modulators, displayers, and color extraction for imaging.
Perception And Proprioception In Relation To Masticatory Act

Perceptionis the consciousmentalregistration of a sensorystimulus. It involves interpretation of often ambiguous, insufficient, or overwhelming information in the light of your knowledge, beliefs, goals and expectations. Proprioception means” awareness of oneself”2.It keeps us aware of the position of the body, extremities, mandible etc proprioceptor impulses participate in reflex adjustments. They are group of enteroreceptors that provide information regarding the position of parts of body in space and the receptors of posture and movements . They are highly specialized types of mechanoreceptor ( consist of the terminal dendrites of sensory neurons and are encapsulated in structures of connective tissue or free) responding to tension or movement included by associated structures.

The alleviation activity of selenium against cadmium phytotoxicity in date palm Phoenix dactylifera L.

A laboratory experiment has been performed to investigate possible beneficial role of selenium (Se) in alleviation of cadmium (Cd) toxicity. Date palm Phoenix dactylifera L. offshoots at three years old were subjected to individually Cd at two concentrations (3 and 9 mg.kg -1 ) or simultaneously with Se at 1 and 15 mg.kg -1 . Results show that, Cd treatments alone led to increased accumulation of malondiladehyde (MDA), H2O2, proline and peroxidase (POD) activity, per contra, reduction chlorophyll content, chlorophyll stability index (CSI) and membrane stability index (MSI), particularly at high concentration. Cd phytotocixity was alleviated when added at same time with Se at 15 mg.kg -1 , no significant effect was recorded of Se at 1 mg.kg 1 to negative effects of Cd even at low concentration. MDA increased 62.72 and 53.05%, H2O2, 56.99 and 43.57%, proline 71.35 and 57.16%, POD activity 45.59 and 36.93% while the reduction of chlorophyll a was 31.66 and 11.90%, chlorophyll b 12.78 and 7.76%, total chlorophyll 23.32 and 10.66%, CSI 23.42 and 10.93% and MSI 31.87 and 25.79% for alone Cd at 9 mg.kg -1 or with Se at 15 mg.kg -1 treatments respectively, compared to control plants. The results of this study reported the addition of Se at 15 mg.kg -1 led to alleviated Cd toxicity in date palm plants.
Planning Gone Hog Wild: Mega-Hog Farm in a Mountain West County

PLANNING GONE HOG WILD: MEGA-HOG FARM IN A MOUNTAIN WEST COUNTY Jeffrey M. Sanders Department of Geography Master of Science Lacking the natural amenities of “New West” counties, some rural communities have attempted to attract land use activities that are normally seen as undesirable. One example of these undesirable industries is the hog concentrated animal feeding operation, or CAFO. While a number of studies have explored the socio-economic and environmental aspects of hog farms, few studies have focused on the planning process and evaluated its effectiveness in dealing with the threats and challenges that a CAFO poses. This qualitative study used interviews, observations, public meeting minutes, and other written sources of data to evaluate whether or not a rural, western community, Beaver County, Utah, was able to successfully plan for one of the largest hog operations in the United States. The evidence suggested that the majority of planning efforts failed in the short-term, but were more successful in the long-term. Despite any relative success, the proposal generated intense controversy in the small community. Crucial to any planning achievement was the input and guidance provided by the state environmental agency. This research highlights the need for long-range planning as well as the importance of public participation in the planning process.
Condition Numbers for Indefinite Least Squares Problem with Multiple Right-Hand Sides

In this paper, we investigate the condition numbers for indefinite least squares problem with multiple right-hand sides. The normwise, mixed and componentwise condition numbers and the corresponding structured condition numbers are presented. The structured matrices under consideration include the linear structured matrices, such as the Toeplitz, Hankel, symmetric, and tridiagonal matrices, and the nonlinear structured matrices, such as the Vandermonde and Cauchy matrices. Numerical examples show that the structured condition numbers are tighter than the unstructured ones.
Digital Prototyping of a Series Elastic Actuator for Exoskeletons

In general, the actuators of the mechanical systems are always rigidly connected to the load to be moved. This can be observed in the hydraulic systems of agricultural, highway construction and mining equipment and in elevation and cargo transportation, among others. Unlike rigid actuators, a series elastic actuator (SEA) contain an elastic element in series with the mechanical energy source. Such an elastic element gives SEA’s several unique properties compared to rigid actuators, including tolerance to impact loads, low mechanical output impedance, passive mechanical energy storage, and increased peak power output. These properties align with requirements of robustness, high-power output, and energy efficiency placed on legged actuation systems. As a result, SEA’s have been widely adopted in the fields of legged robotics and human orthotics. In the present paper, it is presents the digital prototyping of an actuator with an elastic element inserted in series with the load. Digital prototyping is an efficient approach to product development that lets someone design, visualize, and simulate parts and mechatronic devices. It is possible to make detailed design of the device and get the data for dynamic model simulation. The goal here is virtually create an elastic actuator for applications in mechatronics exoskeletons and prostheses and for robot manipulators in non-structured environments. It is done a digital prototyping of a tubular actuator design which encapsulates the mechanical and electrical components and sensors. The digital prototype dimensions, mass and inertia properties are used to build the dynamic model for simulations and implementation of a controller.
Body weight dissatisfaction and its correlates among Brazilian adolescents

OBJECTIVE: This study examined the prevalence of body weight dissatisfaction and its relationship to physical activity and nutritional status in adolescents. METHOD: The study enrolled 2,288 adolescents. The dependent variable was body weight dissatisfaction. The independent variables were physical activity and nutritional status. The confounders were gender, and economic condition. Associations between dependent and independent variables were analyzed through the chi-square test and the magnitude of the associations was estimated by Poisson regression. RESULTS: A total of 56.6% of adolescents were not satisfied with their weight, with 17.9% wanting to increase it, while 37.7% wanted to decrease their weight. In boys and girls, body weight dissatisfaction was associated with nutritional status, abdominal obesity and physical activity in crude analyses. After adjustments, nutritional status and abdominal obesity remained significantly associated to body weight dissatisfaction in both sexes. CONCLUSION: A high prevalence of body weight dissatisfaction was identified, which was associated with the nutritional status and abdominal obesity in adolescents.
Adsorption Isotherm and Equilibrium Process of Dye Wastewater onto Camphor Sawdust

The textile industry plays an important role in the economies of numerous countries around the world. But the dye wastewater from the textile industry has become one of the most serious environmental problems today for its harm, especially in aquatic environments. Dyes are aromatic organic colorants and have potential applications in textile, plastic, rubber, paper and food industries. Therefore, the treatment of dye wastewater is of interest. The potential and effectiveness of the camphor sawdust was studied as an alternative adsorbent for the removal of dye wastewater. The dye Congo red was used as the pollutant. The effects of camphor sawdust dosage, pH in aqueous solution, the contact time and dye Congo red concentration on dye Congo red adsorption by the camphor sawdust were investigated. The results showed that the reaction factors had an important influence on adsorption process. The adsorption isotherm fitted better with the Langmuir model and the adsorption process was an endothermic process. The maximum adsorption capacity obtained from the Langmuir isotherm is 29.51 mg/g.

Why Creativity is Sexy: A Review of the Evidence of Sexual Selection for Creative Abilities in Humans

Creativity is an essential human trait, yet there is no consensus among scholars as to why our species have developed creative abilities. Most evolutionary explanations rely on the survival value of such abilities, but generally fail to explain why other species have not evolved similar capacities or why so many human products of creativity have little to no practical value. Sexual selection is an evolutionary force which has the potential to shed new light on this investigation by regarding creativity as a fitness indicator that has evolved for the purposes of courtship and mating. The paper at hand reviews the empirical evidence in support of this hypothesis.
Convection in three-dimensional vibrofluidized granular beds

We study convective motion in vertically vibrated three-dimensional granular beds by comparing the predictions of a model based on a hydrodynamic description to Navier–Stokes order with experimental results obtained using positron emission particle tracking (PEPT). The three-dimensional conservation equations relating mass, momentum and energy are solved using the finite element (FE) method for a viscous vibrofluidized bed by using only observable system parameters such as particle number, size, mass and coefficients of restitution. The mean velocity profiles from the viscous model show reasonable agreement with the experimental results at relatively low altitudes for the range of experimental values studied, though the velocity fields at higher altitudes were systematically underestimated by the model. We confirm that the convection rolls are influenced by the sidewall coefficient of restitution and demonstrate the scaling relationships that operate, where increasing amplitude of vibration leads to a reduction in the angular velocity of the rolls.
Assessment of the antimicrobial wild-type minimum inhibitory concentration distributions of species of the Lactobacillus delbrueckii group

Determination of antimicrobial wild-type minimum inhibitory concentration (MIC) distributions is a prerequisite before differentiating susceptible bacteria from bacteria with acquired resistance. The antimicrobial susceptibility was determined for 190 strains of eight species of the Lactobacillus delbrueckii group. These were L. acidophilus, L. amylovorus, L. crispatus, L. delbrueckii, L. helveticus, L. gallinarum, L. gasseri and L. johnsonii. For most antimicrobial agents a clear distinction between susceptible and resistant bacteria was observed. Tetracycline resistance was abundant among L. johnsonii and L. amylovorus strains isolated from animals, while the L. delbrueckii and L. helveticus strains isolated from dairy products, and L. gasseri isolated from humans, rarely contained acquired resistance.Abstract(MIC) 8 190 (L. acidophilus) (L. amylovorus) (L. crispatus) (L. delbrueckii) (L. helveticus) (L. gallinarum) (L. gasseri) (L. johnsonii) 8 (L. johnsonii) (L. amylovorus) (L. delbrueckii) (L. helveticus) (L. gasseri)RésuméLa détermination de la distribution des concentrations minimales inhibitrices d’antibiotiques sur des souches sauvages est un préalable pour différencier les bactéries sensibles de celles qui ont acquis une résistance. La sensibilité aux antibiotiques a été déterminée chez 190 souches de 8 espèces du groupe Lactobacillus delbrueckii : L. acidophilus, L. amylovorus, L. crispatus, L. delbrueckii, L. helveticus, L. gallinarum, L. gasseri et L. johnsonii. Pour la plupart des antibiotiques, une distinction claire entre bactéries sensibles et bactéries résistantes était observée. La résistance à la tétracycline était abondante parmi les souches de L. johnsonii et de L. amylovorus isolées d’animaux, alors que la résistance acquise des souches de L. delbrueckii et L. helveticus isolées de produits laitiers, et de L. gasseri isolées d’humains, était rare.
Design Methodologies and Co-Design Options for Novel 3D Technologies

Three-dimensional (3D) technologies enable faster, smaller and more energy efficient systems. Moreover, after more than two decades of research, the technologies are mature and ready for industrial application. However, only few developers make use of them and adoption by market is lagging behind. One of the main reasons is that 3D technologies are difficult to be integrated into existing two-dimensional (2D) design flows, with the latter often wasting the potential promised by 3D technologies. Therefore, 3D-compatible design flows, with an emphasis on co-design between various 3D hierarchy levels, are required. In this paper, we first give an overview of the most relevant and mature 3D technologies. Subsequently, we investigate related design methodologies in order to find so far neglected potentials for design optimization. The presented co-design options enable designers to better exploit the potential offered by novel 3D technologies.
NanostructuredMesoporous Silicas for Bone Tissue Regeneration

The research on the development of new biomaterials that promote bone tissue regeneration is receiving great interest by the biomedical scientific community. Recent advances in nanotechnology have allowed the design of materials with nanostructure similar to that of natural bone. These materials can promote new bone formation by inducing the formation of nanocrystalline apatites analogous to the mineral phase of natural bone onto their surfaces, i.e. they are bioactive. They also stimulate osteoblast proliferation and differentiation and, therefore, accelerate the healing processes. Silica-based ordered mesoporous materials are excellent candidates to be used as third generation bioceramics that enable the adsorption and local control release of biological active agents that promote bone regeneration. This local delivery capability together with the bioactive behavior of mesoporous silicas opens up promising expectations in the bioclinical field. In this review, the last advances in nanochemistry aimed at designing and tailoring the chemical and textural properties of mesoporous silicas for biomedical applications are described. The recent developed strategies to synthesize bioactive glasses with ordered mesopore arrangements are also summarized. Finally, a deep discussion about the influence of the textural parameters and organic modification of mesoporous silicas on molecules adsorption and controlled release is performed.
Hydrodynamic damped pitch motion of tension leg platforms

Because of fluctuation in leg tension, pitch motion is very effective fatigue and life safety of leg elements in tension leg structures (TLSs). In this paper an exact solution for pitch vibration of a TLS interacting with ocean wave is presented. The legs of TLP are considered as elastic springs. The flow is assumed to be irrotational and single-valued velocity potentials are defined. The effects of radiation and scattering are considered in the boundary value problem. Because of linear behavior of legs during wave excitation, ignoring coupling effects with other degrees of freedom, the analytical solution of pitch response has good agreement with the real behavior of the structure.

Krill-Herd Support Vector Regression and heterogeneous autoregressive leverage: evidence from forecasting and trading commodities

In this study, a Krill-Herd Support Vector Regression (KH-vSVR) model is introduced. The Krill Herd (KH) algorithm is a novel metaheuristic optimization technique inspired by the behaviour of krill herds. The KH optimizes the SVR parameters by balancing the search between local and global optima. The proposed model is applied to the task of forecasting and trading three commodity exchange traded funds on a daily basis over the period 2012–2014. The inputs of the KH-vSVR models are selected through the model confidence set from a large pool of linear predictors. The KH-vSVR’s statistical and trading performance is benchmarked against traditionally adjusted SVR structures and the best linear predictor. In addition to a simple strategy, a time-varying leverage trading strategy is applied based on heterogeneous autoregressive volatility estimations. It is shown that the KH-vSVR outperforms its counterparts in terms of statistical accuracy and trading efficiency, while the leverage strategy is found to be successful.
Fatty acid, triacylglycerol composition and antioxidant properties of date seed oil

Oil is one of the major components of date seed alongside dietary fibre, carbohydrate, protein, moisture and ash. Therefore, the present work focused on the extraction of oil from five varieties of date seed using Soxhlet extraction method and subsequently characterised their physicochemical and antioxidant properties accordingly. Oil extracted from the seeds ranged between 8 to 9.8%, whereas the iodine values were between 48.7 to 55.5 g I2/100g. Furthermore, oleic and lauric acids were revealed as the main fatty acids present in the date seed oil, with LaOO (La: lauric acid; O: oleic acid) as the main triacylglycerol. The total phenolic content in the oil ranged from 7.96 to 17.72 mg GAE/g oil, while the antioxidant activity, expressed as EC50, ranged from 5.17 to 17.18 mg/mL. Additionally, the highest reducing activity was observed at 4mg/mL. Hence, oil characteristics are dependent on the type of date, thus indicating that different potential applications may be suggested.
EVALUATION OF THE EFFECT OF AQUADEKS SUPPLEMENT VERSUS SINGLE VITAMINS ON OXIDATIVE STRESS

Breast cancer is a very important epidemiologic problem and the most common cause of death in women. Oxidative stress play an important role in this disease. Antioxidants such as A, C, E, K, D vitamins have drawn the attention of many scientists for reducing oxidative stress. AquADEKs is one of the antioxidant supplements. The purpose of this study was to investigate the effect this supplement in reducing oxidative stress in breast cancer. In this applied research, 38 BALB-C mice were divided into 4 groups. In the sera of the mice, the levels of catalase, superoxide dismutase, and total antioxidant capacity were measured by the Elisa method. Data analysis was performed using ANOVA and Graphpad. The catalase level significantly increased in mice that received vitamin supplements and were implanted with cancer cells (P = 0.049) this relationship was not significant with vitamin D. Superoxide dismutase levels significantly increased in the mice that received vitamin supplements and were implanted with cancer cells (P = 0.024) but this relationship was not significant with vitamin D. The total antioxidant capacity increased significantly in mice that received vitamin supplements and were implanted with breast cancer cells (P < 0.001) and Fariba Nabatchian et al Research Article 6770 IJBPAS, December, 2015, 4(12) this relationship was significant with vitamin D. The use of AquADEKs as supplement had a significant correlation with the levels of catalase, superoxide dismutase, and total antioxidant capacity. Antioxidant markers can be improved with the use of AquADEKs if this supplement is imported and available in market.
