Conception Des Cordes D’Assurance Horizontales Pour La Protection Contre Les Chutes De Hauteur : Mise À Jour Du Guide Technique, Bertrand Galy, André Lan

Rapports de recherche scientifique

Les chutes de hauteur sont encore aujourd’hui une des causes majeures d’accidents du travail. Trop souvent, les travailleurs ne s’attachent pas, faute de point d’ancrage disponible, ou parce qu’ils trouvent que les points d’attache fixes restreignent trop leurs mouvements. Cette restriction peut toutefois être levée grâce aux systèmes de corde d’assurance horizontale (SCAH). Le présent rapport constitue la mise à jour du guide technique T-18 publié en 1991 et rend ce dernier caduc. Cette mise à jour était devenue nécessaire à la suite de l’introduction, en 2001, au Code de sécurité pour les travaux de construction (CSTC), de l’obligation d’équiper …

Solutions Visant L’Amélioration Des Conditions De Santé Et De Sécurité Des Poseurs De Revêtements De Sol, Monique Lortie, Sylvie Nadeau, Steve Vezeau

Rapports de recherche scientifique

La pose de revêtement de sol se divise en différentes spécialités : céramique, bois et revêtement souple. C’est ce dernier secteur qui nous intéresse, soit la pose de tapis (accrochés ou collés; en rouleau, en tuiles) ou de matériaux résilients (linoléum, vinyle, caoutchouc, gazon synthétique, etc.). Le métier de poseur de revêtement de sol est exigeant sur le plan physique (manutention de rouleaux très lourds, travail à genou prolongé, épandage de colle sur de grandes surfaces), mais aussi en matière de savoir-faire à développer. La pose exige de la précision, entre autres, pour ajuster les motifs et effectuer les raccords. …

The Protective Role Of Mlcp-Mediated Erm Dephosphorylation In Endotoxin-Induced Lung Injury In Vitro And In Vivo, Anita Kovacs-Kasa, Boris A. Gorshkov, Kyung-Mi Kim, Sanjiv Kumar, Stephen M. Black, David J. Fulton, Christiana Dimitropoulou, John D. Catravas, Alexander D. Verin

Bioelectrics Publications

The goal of this study was to investigate the role of MLC phosphatase (MLCP) in a LPS model of acute lung injury (ALI). We demonstrate that ectopic expression of a constitutively-active (C/A) MLCP regulatory subunit (MYPT1) attenuates the ability of LPS to increase endothelial (EC) permeability. Down-regulation of MYPT1 exacerbates LPS-induced expression of ICAM1 suggesting an anti-inflammatory role of MLCP. To determine whether MLCP contributes to LPS-induced ALI in vivo, we utilized a nanoparticle DNA delivery method to specifically target lung EC. Expression of a C/A MYPT1 reduced LPS-induced lung inflammation and vascular permeability. Further, increased expression of the …

Dental Hygiene Faculty Publications

Purpose: The purpose of this study was to assess dental hygienists’ interests, current involvement, formal education, views, comfort levels, and intentions for involvement with disaster preparedness and response.

Methods: Dental hygienists (n=400) were asked to respond to a 21-item online survey. Data was analyzed using descriptive statistics, chi-square goodness-of-fit tests, and a paired-samples t-test. Common themes were identified and categorized from open-ended questions.

Results: A response rate of 84% (n=334) was obtained. Most respondents (97%) reported no involvement with disaster preparedness and response; however, a majority (86%) reported interest. Of those who indicated an interest in disaster preparedness and response, …

Latina Titans: A Journey Of Inspiration, Velma D. Menchaca, Shirley J. Mills, Filomena Leo

Organization and School Leadership Faculty Publications

This qualitative research examined the journey of renowned female leadership in higher education. Two top level Latina administrators of universities were interviewed extensively to discover their journey to leadership. The theoretical framework used was Latina critical race theory, feminist theory, and counter-storytelling. Themes that surfaced were strong supportive mother, fervent faith, humble beginnings, mentors, intelligence, and challenges not obstacles. These guiding themes serve as a path for Latinas who aspire to higher educational leadership positions.

Anatomy, Implant Selection And Placement Influence Spine Mechanics Associated With Total Disc Replacement, Justin F.M. Hollenbeck

Electronic Theses and Dissertations

Through aging and injury, the intervertebral disc of the lumbar spine can undergo degeneration, leading to collapse of the vertebrae and low back pain, a symptom that affects half the adult population in any given year. In an effort to reduce low back pain, total disc replacement treatment removes the degenerated disc, restores natural height and lordosis of the segment, and preserves motion at the joint. Patient anatomy, implant selection, and implant placement play significant roles in a patient's outcomes after total disc replacement surgery. Thus, the objective of the work presented in this thesis was to develop a suite …

Some Key Elements On Entomophagy In Africa: Culture, Gender And Belief, S. Niassy, H. D. Affognon, K. K.M. Fiaboe, K. S. Akutse, C. M. Tanga, S. Ekesi

All Peer-Reviewed Publications

Edible insects are a natural renewable food resource and, within the context of food security could be one solution for Africa. Although, entomophagy is still being practiced in Africa, there is a degree of rejection in certain milieu due to negative images associated with insects and poor awareness efforts. In order to understand the key elements that govern entomophagy in Africa, we conducted an online survey on edible insects in African countries and documented the importance of insects, cultures and believes associated to their use. We eventually looked at gender participation in entomophagy. Study showed that insect consumption can be …

Mitochondrial Coding Genome Analysis Of Tropical Root-Knot Nematodes (Meloidogyne) Supports Haplotype Based Diagnostics And Reveals Evidence Of Recent Reticulate Evolution, Toon Janssen, Gerrit Karssen, Myrtle Verhaeven, Danny Coyne, Wim Bert

All Peer-Reviewed Publications

The polyphagous parthenogenetic root-knot nematodes of the genus Meloidogyne are considered to be the most significant nematode pest in sub-tropical and tropical agriculture. Despite the crucial need for correct diagnosis, identification of these pathogens remains problematic. The traditionally used diagnostic strategies, including morphometrics, host-range tests, biochemical and molecular techniques, now appear to be unreliable due to the recently-suggested hybrid origin of root-knot nematodes. In order to determine a suitable barcode region for these pathogens nine quickly-evolving mitochondrial coding genes were screened. Resulting haplotype networks revealed closely related lineages indicating a recent speciation, an anthropogenic-aided distribution through agricultural practices, and evidence …

Active Aggregation Among Sexes In Bean Flower Thrips (Megalurothrips Sjostedti) On Cowpea (Vigna Unguiculata), Saliou Niassy, Sunday Ekesi, Nguya K. Maniania, Benedict Orindi, Gerald B. Moritz, Willem J. De Kogel, Sevgan Subramanian

All Peer-Reviewed Publications

Male sexual aggregations are a common territorial, mating-related or resource-based, behaviour observed in diverse organisms, including insects such as thrips. The influence of factors such as plant substrate, time of day, and geographic location on aggregation of thrips is uncertain, therefore we monitored the dispersion of male and female bean flower thrips (BFT), Megalurothrips sjostedti (Trybom) (Thysanoptera: Thripidae), on cowpea, Vigna unguiculata (L.) Walp. (Fabaceae), over three cowpea growth stages and across three cowpea-growing areas of Kenya. Our results indicated that for all the crop growth stages, the density of BFTs varied over the time of day, with higher densities …

Rapid And High Throughput Molecular Identification Of Diverse Mosquito Species By High Resolution Melting Analysis., Yvonne Ukamaka Ajamma, Enock Mararo, David Omondi, Thomas Onchuru, Anne W.T. Muigai, Daniel Masiga, Jandouwe Villinger

All Peer-Reviewed Publications

Mosquitoes are a diverse group of invertebrates, with members that are among the most important vectors of diseases. The correct identification of mosquitoes is paramount to the control of the diseases that they transmit. However, morphological techniques depend on the quality of the specimen and often unavailable taxonomic expertise, which may still not be able to distinguish mosquitoes among species complexes (sibling and cryptic species). High resolution melting (HRM) analyses, a closed-tube, post-polymerase chain reaction (PCR) method used to identify variations in nucleic acid sequences, has been used to differentiate species within the Anopheles gambiae and Culex pipiens complexes. We …

Mosquito Host Choices On Livestock Amplifiers Of Rift Valley Fever Virus In Kenya, David P. Tchouassi, Robinson O.K. Okiro, Rosemary Sang, Lee W. Cohnstaedt, David Scott Mcvey, Baldwyn Torto

All Peer-Reviewed Publications

Background: Animal hosts may vary in their attraction and acceptability as components of the host location process for assessing preference, and biting rates of vectors and risk of exposure to pathogens. However, these parameters remain poorly understood for mosquito vectors of the Rift Valley fever (RVF), an arboviral disease, and for a community of mosquitoes. Methods: Using three known livestock amplifiers of RVF virus including sheep, goat and cattle as bait in enclosure traps, we investigated the host-feeding patterns for a community of mosquitoes in Naivasha, an endemic area of Rift Valley fever (RVF), in a longitudinal study for six …

Plant Resting Site Preferences And Parity Rates Among The Vectors Of Rift Valley Fever In Northeastern Kenya, Samwel O. Arum, Christopher W. Weldon, Benedict Orindi, Caroline Tigoi, Francis Musili, Tobias Landmann, David P. Tchouassi, Hippolyte D. Affognon, Rosemary Sang

All Peer-Reviewed Publications

Background: Mosquito lifespan can influence the circulation of disease causing pathogens because it affects the time available for infection and transmission. The life-cycle of mosquitoes is determined by intrinsic and environmental factors, which can include the availability of hosts and suitable resting environments that shelter mosquitoes from extreme temperature and desiccating conditions. This study determined the parity rates (an indirect measure of survival) and plant resting preference of vectors of Rift Valley fever (RVF) in northeastern Kenya. Methods: Resting mosquitoes were trapped during the rainy and the dry season using a Prokopack aspirator from vegetation, whereas general adult populations were …

The potential benefits of physiology for conservation are well established and include greater specificity of management techniques, determination of cause–effect relationships, increased sensitivity of health and disturbance monitoring and greater capacity for predicting future change. While descriptions of the specific avenues in which conservation and physiology can be integrated are readily available and important to the continuing expansion of the discipline of ‘conservation physiology’, to date there has been no assessment of how the field has specifically contributed to conservation success. However, the goal of conservation physiology is to foster conservation solutions and it is therefore important to assess whether …

Globalization Of Higher Education In United Arab Emirates, John S. Spranza Iii

Journal of Higher Education & Student Affairs

This article explores the educational history of the United Arab Emirates, a young and vastly wealthy nation located in the Middle East. A nation for just over 40 years, its leaders have struggled with educating and supporting its native population and managing the massive infusion of immigrants created by the progressive job markets established within its borders. With a mix of mandated free education for natives and a lucrative educational investment market from various other nations, the educational structure in the UAE has become a unique system that attracts students and faculty from around the world. The opulent landscapes of …

Fruit Fly Species Composition, Distribution And Host Plants With Emphasis On Vegetable-Infesting Species, Chrysantus M. Tanga, Ivan Rwomushana

All Peer-Reviewed Publications

Vegetable crops hold a key position in smallholder agricultural production systems in Africa due to the number of farmers involved, income generation, employment opportunities, and enhancement of food and nutritional security. In many developed countries, demand for vegetables continues to grow due to increased awareness of the nutritional benefits, thereby stimulating increased domestic production and also imports from Africa. However, many pests threaten the productivity of the vegetable sector. Key amongst these are tephritid fruit flies that inflict both direct and indirect losses; alien invasive species are often responsible for severe ecological and economic impacts. The highly invasive and polyphagous …

Phylogenetic Analysis Of Bunyamwera And Ngari Viruses (Family Bunyaviridae, Genus Orthobunyavirus) Isolated In Kenya, C. Odhiambo, M. Venter, O. Lwande, R. Swanepoel, R. Sang

All Peer-Reviewed Publications

Orthobunyaviruses, tri-segmented, negative-sense RNA viruses, have long been associated with mild to severe human disease in Africa, but not haemorrhagic fever. However, during a Rift Valley fever outbreak in East Africa in 1997-1998, Ngari virus was isolated from two patients and antibody detected in several others with haemorrhagic fever. The isolates were used to identify Ngari virus as a natural Orthobunyavirus reassortant. Despite their potential to reassort and cause severe human disease, characterization of orthobunyaviruses is hampered by paucity of genetic sequences. Our objective was to obtain complete gene sequences of two Bunyamwera virus and three Ngari virus isolates from …

The Case For Prioritism: Part 1, Christopher R. Little

Great Commission Research Journal

The global evangelical missions movement has embraced holism or integral mission as a framework for engaging the nations. Many astute observers maintain that this development indicates that present-day evangelicals are following in the footsteps of ecumenicals and repeating the mistakes of the past. The matter of the relationship between proclamation and social action in the mission of the church must therefore be revisited for the sake of the world. The first installment of this article seeks to highlight why the debate is still necessary, clarify the fundamental differences between prioritism and holism, recount the road to evangelical holism, and address …

Sometimes They Come Back: Examining The Threat Of Associated And Non-Associated And/Or Mentally Ill School Violence Perpetrators, Gordon A. Crews

Criminal Justice Faculty Publications

In this chapter it is argued that school violence and its potential in K-12 schools cannot be dealt with by simply removing the troublesome/problematic students from classrooms and/or school grounds. The expelling, suspending, incarcerating, or placing of a juvenile in an alternative school setting may only increase their anger against their former school and teachers. An anger which may continue to grow throughout their lives. Moreover, there is a growing trend of students who have failed to achieve in life returning to their former school and committing acts of violence. The author focuses on two types of these perpetrators. First, …

The Significant Other: A Longitudinal Analysis Of Significant Samples In Journalism Research, 2000–2014, Ben S. Wasike

Communication Faculty Publications

This study examined the methodology journalism scholars use when studying significant samples, or “those persons who have attained an unusually pervasive and lasting reputation, regardless of whether that reputation be great or small.” Using Simonton’s work as the theoretical guide, the study content analyzed a census of articles published in 10 major journalism journals from 2000 to 2014. Results showed that the typical study examining significant samples is psychometric and is also quantitative, nomothetic, longitudinal, singularly focused, and exploratory. In addition, it uses macro units and observes the subject indirectly. The study also found similarities between the study of significant …
