There is an alarming increase of cancer cases alongside an increased pesticide use in agriculture in Kenya. This has raised concerns about possible links between pesticide exposure and cancer incidences. This study ...
This study investigated the influence of principals' management practices of institutional working conditions on students' academic performance in public day secondary schools in Kitui West Sub-County, Kenya. The study ...
The adoption of Artificial Intelligence (AI) in customer engagement is transforming enterprise growth in Kenya by enhancing service delivery, marketing strategies, and decision-making processes. This study examines the ...
Mathematical modeling has enabled epidemiologist to understand best the dynamics of infectious diseases, their impact and future predictions on their transmission and existence. Deterministic Susceptible–Vaccinated–Expos ...
Associated with every commuting m-tuples of operators on a complex Hilbert space X is its Aluthge transform. In this paper we show that every commuting m-tuples of operators on a complex Hilbert space X and its Aluthge ...

Cancer is a menace to public health globally. Human Papillomavirus (HPV) is a sexually transmitted virus and has been linked to several cancers such as cervical cancer, anal cancer, oropharyngeal cancer and neck cancer. ...
The Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-COV-2) is a strain of Coronavirus that causes Coronavirus Disease 2019 (COVID-19). The respiratory illness responsible for the COVID19 pandemic began in December ...
Two enduring ideological divisions in biodiversity conservation concern whether conservation should prioritize (i) the interests of people or wild animals and (ii) the interests of individual animals or groups of animals. ...
Climate change poses a significant threat to the survival of many species. Although protected areas can slow down biodiversity loss, they often lack systematic planning and do not integrate genetic diversity. Genetic ...
