Geographical segregation on fertility of women in Kisumu East Sub county, Kisumu county, Kenya.

Abstract/Overview v ABSTRACT Fertility and geographical segregation are some of the major factors influencing human population growth. The fertility rate of Kisumu East Sub County is rated at 4.8 per woman exceeding the average for the county, national and the global which is 4.2, 3.4 and 2.3 respectively per woman. It has been established that the segregation may influence fertility, however, it was not well understood how various aspects of segregation influence fertility. The purpose of t...

Infuence of land use practices on dominant tree species diversity, richness, evenness, and abundance in Ugenya Sub-county, Kenya

Abstract/Overview Change in Land use practices are important indicators of socio-cultural and economic advancement. The common practices for example, rapid human settlement development and unsustainable livestock farming affect distribution of the dominant trees, conversely, Influence of the change in practices on the tree species diversity Richness, Evenness, and abundance is understood. Farm-forestry is contributing to the restoration of trees. However, information relating the 10% Farm-fo...

Effect of anthropogenic activities on terrestrial flora and Fauna species in Rachuonyo South sub county, Homabay county Kenya

Abstract/Overview Globally, terrestrial flora and fauna species are at the brink of extinction yearly due to the increase in human population. Yearly, species reduce at 34% globally and 68% in Kenya as result of increased anthropogenic activities. The current rapid population growth has led to increased anthropogenic activities and population pressure on the land posing threats to the survival of terrestrial flora and fauna species. In Kenya, Rachuonyo South Sub County is characterized by ri...

ADAPTATION STRATEGIES TO CLIMATE CHANGE AND THEIR DETERMINANTS BY SMALLHOLDER FARMERS: THE CASE OF CHIRO WOREDA OF OROMIA NATIONAL REGIONAL STATE, ETHIOPIA

Abstract: Though climate change is a global phenomenon, it highly impacts smallholder farmers whose livelihood depends on rain-fed agriculture. As a result, the study was conducted with the objective of examining the perception level, the types of climate change adaptation strategies pursued, and factors influencing the adaptation strategies focusing on randomly selected 175 smallholder farmers from three kebeles in Chiro woreda of West Hararghe zone. Household survey, focus group discussion...

Ti–Si–Zr TERNARY MIXED OXIDE NANOCOMPOSITE: CHEMICAL SYNTHESIS, STRUCTURAL AND OPTOELECTRONIC CHARACTERISTICS

Abstract: In this work Ti-Si and Si-Ti-Zr binary and ternary mixed oxide nanocomposites were synthesized through sol-gel route. The structural and optoelectronic properties characteristics analyzed using the data generated from PL, UV-vis. and XRD spectrometry. The binary and ternary nanocomposite were synthesized with different zirconia content and calcination temperatures using Ti(OC3H7)4 (titanium(IV) propoxide) (TTIP), Si(OC2H5)4 (tetraethylorthosilicate) (TEOS), and Zr(OCH2CH2CH3)4 (zir...

Influence of Buffer Zone Regimes on Treespecies Health, Richness, Abundance and Density in Kakamega Forest, Kakamega County, Kenya

Abstract/Overview Worldwide, Buffer zone regimes (BZRs) have been established as designated areas to protect tropical forests from human activities. In Kenya, Nyayo Tea Zone (NTZ) was established around all gazetted forests as BZR. In areas where soil was not ideal for tea, Exotic Tree Plantations (ETP) was established though some parts Open Edge (OE) still exist. However, there are minimal studies on how the BZRs (OE, ETP, and NTZ) area influences tree species; health; richness; abundance a...

Influence of Crop Diversification On the Resilience Of Smallholder Farmers in Bungoma South Sub- County, Kenya

Abstract/Overview Recognition that many agriculture-based economies have few other livelihood strategies has generated the desire to build resilience among smallholder farmers. Globally, due to rapid population growth and continual urban sprawl, average arable land per household is shrinking and hence crop diversification is gaining increased importance in the quest for solutions to the perennial food security problems in most of Sub-Saharan countries. Crop diversification is seen as the mos...

Longitudinal trajectories of four domains of parenting in relation to adolescent age and puberty in nine countries

Abstract/Overview Children, mothers, and fathers in 12 ethnic and regional groups in nine countries (N = 1,338 families) were interviewed annually for 8 years (Mage child = 8–16 years) to model four domains of parenting as a function of child age, puberty, or both. Latent growth curve models revealed that for boys and girls, parents decrease their warmth, behavioral control, rules/limit‐setting, and knowledge solicitation in conjunction with children’s age and pubertal status as childr...

Cross‐Cultural Associations of Four Parenting Behaviors With Child Flourishing: Examining Cultural Specificity and Commonality in Cultural Normativeness and Intergenerational …

Abstract/Overview Families from nine countries (N = 1,338) were interviewed annually seven times (Mage child = 7–15) to test specificity and commonality in parenting behaviors associated with child flourishing and moderation of associations by normativeness of parenting. Participants included 1,338 children (M = 8.59 years, SD = 0.68, range = 7–11 years; 50% girls), their mothers (N = 1,283, M = 37.04 years, SD = 6.51, range = 19–70 years), a...

Invention and application of epoch of Kifilideen’s Sum Formula for Kifilideen’s General Matrix Progression Series of infinite terms in solving real-world problems

Kifilideen’s general matrix progression series of infinite terms is the summation of values of a collection of progressive members of the numbers series system. The number series system or set has endless terms where terms are progressive into levels and steps (within level) with increasing members set in successive levels and just one member in the first level. This kind of series is needed in determining the overall value(s) of the collection in the progressive members of the system ...

FUNDAMENTAL CONCEPT OF FUZZY SEMIGROUP.

In this work, we briefly present fuzzy operations and related properties. As a precursor for studying fuzzy semigroup, we examine critically the fundamental concept of semigroups.. Finally, we describe some results of fuzzy semigroup with respect to fuzzy operations and α-cut of fuzzy set

Enhancing Dermatological Diagnosis through Machine Learning: A Multi-Class Skin Disease Detection System with Convolutional Neural Network.

This research paper proposes a novel approach to detecting skin diseases using machine learning techniques. The proposed system utilizes image processing techniques to extract features from skin lesion images and then applies machine learning algorithms to classify the lesion into different categories. The proposed system can be evaluated using a large dataset of skin lesion images and the machine can learn itself based on the provided data and achieve high accuracy in detecting various skin ...

COMPARATIVE ANALYSIS OF TURN-AROUND TIME AMONG SELECTED SEAPORTS IN WEST AFRICAN SUB-REGION

Turnaround time of a vessel in a seaport exhibits the capability and ability of a port in providing efficient and effective services. Ship turnaround time is one of the most significant Port performance indicator. This is the total time, spent by the vessel in port, during a given call. It is the sum of waiting time, berthing time, service time (i.e., ship’s time at berth) and sailing delay. West African ports play a crucial role in trade and economy, as 95% of merchandise trade is handled ...

Role of Geoscientist in Diversification of Nigeria Economy

ABSTRACT Nigeria for over five decades now operates mono economy. Despite the diverse natural resources endowed to her by God. This started prior to the end of Biafra war in 1970, when Nigeria taps greatly from crude oil due to global rise in oil price. This over dependent on crude oil is to the disadvantage of other sectors such as; natural gas, solid mineral, water, environment, coal, tourism and agriculture that contributes enormously to the economy of any country like Nigeria. In 2017 N...
