INFLUENCE OF HYDROPHOBIC FLUID (PALM OIL) VARIETIES ON HYGROSCOPIC POTENTIALS OF FOUR VARIETIES OF CASSAVA GARRI AT VARYING STORAGE TEMPERATURES
No full textThis study examined the effects of palm oil varieties (Dura and Pisfera) and their quantities (15 ml, 30 ml, and 45 ml) on the hygroscopic properties of four garri varieties (Poundable, Gamechanger, TMS 1632, and TME 419) at temperatures of 35°C, 45°C, and 55°C. Moisture absorption was assessed by placing 5 g samples of each garri in water baths set at the specified temperatures. The weight of each sample was measured at 30-minute intervals until three consecutive measurements indicated equilibrium. Results revealed that palm oil significantly (p<0.05) reduced moisture absorption across all samples, with Dura oil generally providing a more effective moisture barrier than Pisfera. At 45 ml, Dura oil caused a slight increase (11.63%) in moisture uptake, suggesting saturation, while Pisfera stabilized, indicating different chemical interactions. TME 419 exhibited the lowest (1.8%) moisture absorption, demonstrating superior resistance, whereas TMS 1632 absorbed the most moisture. Elevated temperatures increased moisture uptake, especially in control samples without oil. Kinetic parameters (absorption rate constant, K1 and absorption capacity, K2) varied with temperature and variety, reflecting changes in diffusion rates. The K1 for Pisfera oil decreased from 19.67358 at 35°C to 7.388 at 55°C, while Dura oil decreased from 17.41483 to 10.866 over the same temperature range; conversely, K2 for Pisfera increased from 0.058013 to 0.096799, whereas Dura’s capacity decreased from 0.112241 to 0.058681 with rising temperature. Activation energy analyses showed Dura oil created a more resistant barrier, with values of 1.21 J/mol (TMS 1632), -0.5595 J/mol (TME 419), -0.4489 J/mol (Poundable), and 1.45 J/mol (Gamechanger). The findings suggest that palm oil improves garri’s moisture resistance, with Dura oil being more effective, especially at lower quantities, informing optimal storage practices in humid environments. 
Erythrina foliage as an alternative feed for growing goats in Lao PDR
No full textFoliages from some tropical plants and from different species of the legume Erythrina were examined in five studies assessing the characteristics of these foliages as feed for goats.
Digestibility and feed preference studies showed that ad libitum feeding of foliage from Erythrina (Erythrina variegata), jackfruit (Artocarpus heterophyllus) and kapok (Ceiba pentandra) resulted in a longer time spent eating and more changes in diet selection, feed intake, crude protein (CP) digestibility and nitrogen (N) retention than foliage from jujube (Ziziphus jujube Mill), fig (Ficus racemosa) and mango (Mangifera indica). Supplementation of low quality foliage with water spinach (Ipomoea aquatica) increased intake and apparent digestibility.
In a survey study, three different Erythrina spp., E. indica, E. subumbrans and E. variegata, were found in the north, centre and south of Lao PDR. These species were in limited use as an animal feed on smallholder farms. Erythrina variegata appeared to be a better option in terms of degradability than E. indica and E. subumbrans according to in vitro gas production and in sacco degradation studies.
A cropping study showed that cow manure or mineral fertiliser significantly decreased shoot mortality and increased shoot height and fresh and CP yield of E. variegata foliage compared with no fertiliser. The nutritive value of the foliage did not differ significantly between the fertilised and unfertilised treatments.
Studies on different degrees of processing (fresh or sun-dried) of E. variegata foliage showed similar CP, neutral detergent fibre and acid detergent fibre contents, and no difference in total voluntary intake, when either fresh or dry foliage was fed ad libitum to growing goats.
Four levels of replacement (0, 20, 40 and 60%) of dietary CP with CP from E. variegata foliage resulted in similar dry matter intake, apparent CP digestibility, N retention and carcass characteristics, but total CP intake was significantly higher in goats fed the diet with 60% replacement compared with 20%. Thus CP from E. variegata foliage can replace up to 60% of CP in a mixed diet with soybean meal without any negative effects on animal growth performance

An exploration of the lived experiences of black males in two East Midlands further education (FE) colleges
No full textThis thesis seeks to develop an understanding of how Black males received and perceived education within the further education (FE) sector in England. Using phenomenological inquiry and narratives provided by the Black males I consider how they engaged with education in the post compulsory sector and their views regarding the quality of their educational experience while studying at college. I explore the encounters they experienced in terms of accessing the taught curriculum, their experiences of the institutional cultures in FE and the relationships they were able to form with college staff members. I suggest that race is an underlying feature of many of these encounters and influenced both the nature and the outcome of the encounter. I examine how Black males chose to interact with structures and systems and the mechanisms they developed to help them navigate education, including accessing staff, peer and family support and how these different systems were significant to their achievement within colleges. By using phenomenological inquiry, I present a challenge to some of the more popular presentations of Black males and demonstrate how some Black males use their own agency to promote success within education

Interrelación entre el contenido de metabolitos secundarios de las especies Gliricidia sepium y Tithonia diversifolia y algunas propiedades físicoquímicas del suelo
No full textSe recolectaron muestras de dos plantas forrajeras (hoja peciolo) de las especies Gliricidia sepium y Tithonia diversifolia, en diferentes condiciones edáficas (departamentos del Valle del Cauca y Cesar), y se evaluó su contenido de polifenoles totales, taninos totales, taninos condensados y saponinas. El propósito fue detectar el efecto de las condiciones de conductividad eléctrica sobre la concentración de estas fitobiomoléculas secundarias metabolizadas por la célula vegetal. Se aplicaron técnicas analíticas e instrumentales de la AOAC (2005) para determinar la presencia de dichos fitometabolitos secundarios. Los resultados obtenidos para cada variable se sometieron a un análisis de varianza en doble vía, con el fin de determinar diferencias estadísticas entre zonas muestreadas y especies
evaluadas. Adicionalmente, se realizó un análisis de correlación
múltiple, utilizando el coeficiente de Pearson, con el propósito de detectar las posibles correlaciones entre conductividad eléctrica, y el contenido de los metabolitos secundarios cuantificados en las especies muestreadas. Se concluyó que el contenido de polifenoles totales, taninos totales, taninos condensados y saponinas no presentó diferencias estadísticamente significativas entre las tres zonas muestreadas, y se presentó una alta correlación entre el valor de la conductividad eléctrica del suelo y el contenido de metabolitos secundarios
Narratives on mental health and coping strategies of park rangers from the Amazon Territorial Directorate of National Natural Parks exposed to situations of public risk. Single case study
No full textilustraciones, gráficas, tablasEl presente estudio es una oportunidad para ampliar reflexiones sobre la labor de los guardaparques en Colombia, conocer los impactos de la violencia en la salud mental y proponer estrategias de fortalecimiento desde la psicología. A partir de la metodología cualitativa se realizó una entrevista narrativa para conocer la historia del guardaparque, se transcribió, y bajo el modelo de análisis narrativo en psicología de la salud de Wong & Breheny (2018) se construyó una matriz en la que se organizó y codificó la información por niveles: personal, interpersonal y/o narrativas sociales. A continuación, y con base en el referente teórico de Lazarus y Folkman se triangularon e identificaron las afectaciones y estrategias de afrontamiento. El proceso evidenció que ser guardaparque supone una alta demanda emocional, se confirma la presencia de afectaciones psicológicas cambiantes en el tiempo; en principio el estrés agudo es la principal categoría que recoge los síntomas expresados por el participante, los cuales puede transitar a cuadros de ansiedad, depresión o estrés postraumático de acuerdo a las condiciones particulares en cada situación. El riesgo público e incidentes siempre fueron valorados como una amenaza, en este caso el guardaparque utilizó estrategias principalmente cognitivas para dar manejo a distintas situaciones. Se confirma la importancia de continuar fortaleciendo el acompañamiento psicológico desde el ámbito preventivo, interventivo y de seguimiento, además de promover acciones de articulación e incidencia política que permitan garantizar el acceso a tratamientos psicológicos oportunos y especializados en los casos que lo requieran. (Texto tomado de la fuente)This study is an opportunity to broaden reflections on the work of park rangers in Colombia, learn about the impacts of violence on mental health and propose strengthening strategies from psychology. Based on the qualitative methodology, a narrative interview was carried out to learn the history of the park ranger, it was transcribed, and under the model of narrative analysis in health psychology by Wong & Breheny (2018), a matrix was constructed in which it was organized and he coded the information by levels: personal, interpersonal and / or social narratives. Next, and based on the theoretical reference of Lazarus and Folkman, the effects and coping strategies were triangulated and identified. The process showed that being a park ranger involves a high emotional demand, confirming the presence of changing psychological effects over time; In principle, acute stress is the main category that collects the symptoms expressed by the participant, which can transition to pictures of anxiety, depression or post-traumatic stress according to the particular conditions in each situation. Public risk and incidents were always valued as a threat, in this case the park ranger used mainly cognitive strategies to manage different situations. The importance of continuing to strengthen psychological support from the preventive, interventional and follow-up areas is confirmed, as well as promoting articulation and political advocacy actions that will guarantee access to timely and specialized psychological treatments in cases that require it.Parques Nacionales Naturales- Dirección Territorial AmazoniaMaestríaMagíster en PsicologíaInvestigación cualitativa.
