Abstract:

Agricultural projects and programmes funded by governments and donor agencies often failed to achieve the desired set objective(s) at the system levels. The study tries to assess the existing production practices with a view of coming up with a consensus farmer need in a crop-livestock production system at Ido Local Government Area (LGA). The study used a three-stage-sampling technique to elicit information from 225 respondents. Ido Local Government Area was purposively selected for the study. Three cells were randomly selected for the research, three villages were randomly selected in each cell and twenty-five farmers were selected using the snowball selection technique. The data obtained from the Participatory Rural Appraisal were analyzed using descriptive statistics. The pairwise ranking tool helped in determining the importance of the identified problems from the FGD in the study area. The researcher identified the following problems (Pb) from the focus group discussion; inadequate capital for livestock production (Pb1), poor housing for livestock (Pb2), inadequate nutrition for livestock (Pb3), diseases of crops (Pb4), livestock and predatory attack on crops (Pb5). The pairwise comparison of percentage of Pb1 versus (vs) Pb2 was 80/20%, Pb1 vs Pb3 was 68/32%, Pb1 vs Pb4 was 80/20%, Pb1 vs Pb5 was 12/88%, Pb2 vs Pb3 was 68/32%, Pb2 vs Pb4 was 20/80%, Pb2 vs Pb5 was 20/80%, Pb3 vs Pb4 was 32/68%, Pb3 vs Pb5 was 20/80%, vs Pb4 vs Pb5 was 20/80% respectively. The ultimate farmers’ problem in crop-livestock production systems (CLPS) that needs immediate intervention and technical assistance was inadequate capital as perceived from the responses of the farmers.

Abstract:

Government and non-government organizations (NGOs) interventions to local farmers in the recent past had not yielded the desired result because these interventions were not tailored towards the needs of farmers. However, most information on the needs of target farmers have been very scanty thus, the need to use a bottom top approach to assess farmers' needs in Ibarapa East, Oyo state. A three-stage sampling technique was used to purposively select about 225 respondents. Parameters measured were household characteristics, farm sizes, farm labor availability, seasonal pattern and need to be assessed using a participatory rural appraisal approach comprising of focus group discussion (FGD) and structured questionnaire. Data were analyzed descriptively and the need assessed using the pair-wise ranking and simple matrix. Of challenges listed in FDG among crop-livestock farmers, only five (5) were prioritized as follows; wastage of agricultural products (Pb1), bad road network (Pb2), high cost of agricultural inputs (Pb3), lack of potable water (Pb4) and animal invasion (Pb5). The pairwise comparison of the percentage of Pb1 versus (vs.) Pb2 was 80/20%, Pb1 vs. Pb3 was 90/10%, Pb1 vs. Pb4 was 70/30%, Pb1 vs. Pb5 was 20/80%, Pb2 vs. Pb3 was 70/30%, Pb2 vs Pb4 was 30/70%, Pb2 vs. Pb5 was 10/90%, Pb3 vs. Pb4 was 20/80%, Pb3 vs. Pb5 was 10/90%, vs. Pb4 vs Pb5 was 30/70%, respectively. There were proffered solutions to the problem(s) itemized by the FGD. The animal invasion was ranked highest as farmers' need assessed for possible intervention in Ibarapa East. Governments and NGO funds should be addressing animal invasion for desirable project impact assessment. Les interventions des gouvernements et des organisations non gouvernementales (ONG) auprès des agriculteurs locaux dans un passé récent n'avaient pas donné le résultat souhaité car ces interventions n'étaient pas adaptées aux besoins des agriculteurs. Cependant, la plupart des informations sur les besoins des agriculteurs cibles ont été très rares, ce qui nécessite d'utiliser une approche ascendante pour évaluer les besoins des agriculteurs de l'est d'Ibarapa, dans l'État d'Oyo. Une technique d'échantillonnage en trois étapes a été utilisée pour sélectionner environ 225 répondants. Les paramètres mesurés étaient les caractéristiques des ménages, la taille des exploitations, la disponibilité de la main-d'oeuvre agricole, le profil saisonnier. Ils doivent être évalués à l'aide d'une approche d'évaluation rurale participative comprenant des discussions de groupe et un questionnaire structuré. Les données ont été analysées de manière descriptive et le besoin évalué en utilisant le classement par paires et une matrice simple. Parmi les défis énumérés dans le 'FDG' chez les agriculteurs et les éleveurs, seuls cinq (5) ont été classés comme suit; gaspillage des produits agricoles (le 'Pb' 1), mauvais réseau routier (le 'Pb' 2), coût élevé des intrants agricoles (le 'Pb' 3), manque d'eau potable (le 'Pb' 4) et invasion animale (le 'Pb' 5). La comparaison par paire du pourcentage de 'Pb' 1 versus (vs) 'Pb' 2 était de 80/20%, Pb1 vs Pb3 était de 90/10%, Pb1 vs Pb4 était de 70/30%, Pb1 vs Pb5 était de 20/80% Pb2 vs Pb3 était de 70/30%, le 'Pb' 2 vs le 'Pb4' était de 30/70%, le 'Pb' 2 vs le 'Pb' 5 était de 10/90%, le 'Pb' 3 vs. le 'Pb' 4 était de 20/80%, le 'Pb' 3 vs. le 'Pb' 5 etaient 10/90%,vs le 'Pb' 4 vs le 'Pb'5 était respectivement de 30/70%. Des solutions ont été proposées au (x) problème (s) détaillé (s) par le FGD. L'invasion animale a été classée au premier rang des besoins des agriculteurs évalués pour une éventuelle intervention à l'Estd'Ibarapa. Les gouvernements et les fonds d'ONG devraient s'attaquer à l'invasion animale pour une évaluation de l'impact souhaitable du projet.

Abstract:

Procyanidin (PC) dimers are powerful antioxidants, abundant in plant tissues, and also bioavailable. However, the role of the molecular structure of PCs on their antioxidant properties is still a controversial and not fully understood issue that needs to be addressed in a more specific way. The objective of this study was to analyze the effect of the constituent units, type of interflavan bond, and conformation on the antioxidant properties of PC dimers including PB3, PB4, PB5, PB6, PB7, and PB8, using the density functional theory (DFT) computational method. The analysis was performed in function of parameters that allow determining the ability of the molecules to transfer or to capture electrons, among which the chemical potential, bond dissociation enthalpy (BDE), gap energy, Fukui indices, and charge distribution of HOMO-LUMO orbitals. The factors that showed the most notable effects on the antioxidant properties of the PC dimers were the type of interflavan bond and the conformation. The antioxidant ability of the dimers PB3 and PB4 containing the interflavan bond C4–C8, in their Compact conformation, was very similar to each other but greater than those of dimers PB5, PB6, PB7, and PB8 containing the C4–C6 interflavan bond. PB8 showed the lowest antioxidant ability.

Abstract:

Doped films of TiO2/PbS/CdS have been prepared by successive ionic layer adsorption and reaction (SILAR) method. Bi- and Ag-doped-PbS quantum dot (QD) were produced by admixing Bi3+or Ag+during deposition and the existing forms of the doping element in PbS QD were analyzed. The results show that Bi3+entered the cube space of PbS as donor yielding interstitial doping Bi-doped-PbS QD, while Ag+replaced Pb2+of PbS as acceptor yielding substitutional doping Ag-doped-PbS QD. The novel Bi-doped-PbS/CdS and Ag-doped-PbS/CdS quantum dot cosensitized solar cell (QDCSC) were fabricated and power conversion efficiency (PCE) of 2.4% and 2.2% was achieved, respectively, under full sun illumination.

Abstract:

Objectives: African Americans (AAs) have higher rates of medication nonadherence compared to non-Hispanic whites. In this study, we determined the preliminary feasibility of an 8-week intervention focused on improving culturally-informed illness and medication beliefs, self-efficacy, and medication adherence. Methods: We used purposeful sampling to recruit 8 peer ambassadors (PAs), individuals constituting the advisory board of AAs adherent to their medicines, and 7 peer buddies (PBs), assessed as non-adherent to their diabetes medicines. PAs and PBs were paired. They completed 2 group educational sessions together and one follow-up phone call to PBs by PAs. Results: PAs were mostly female (N = 5, 63%), mean age of 55 years (± 8.3). Similarly, PBs were mostly female (N = 6, 86%), mean age of 56 years (± 6.3). Follow-up interviews with PBs revealed that they liked discussing medication management strategies and diabetes management resources, sharing their diabetes experiences with their PA and connecting with them over the phone. All PBs reported a positive, trusting relationship between them and their PAs. Conclusions: This study demonstrates AAs with diabetes medication adherence challenges are receptive to a peer support mechanism to address culturally informed beliefs and enhance patient-provider communication and self-efficacy.

Abstract:

Crystalline/crystalline blends of polymer have shown advantages in the preparation of new polymeric materials. However, the regulation of co-crystallization in a blend is still full of challenges due to the preferential self-crystallization driven by thermodynamics. Here, an inclusion complex approach is proposed to facilitate the co-crystallization between crystalline polymers, because the crystallization process displays a prominent kinetics advantage when polymer chains are released from the inclusion complex. Poly(butylene succinate) (PBS), poly(butylene adipate) (PBA) and urea are chosen to form co-inclusion complexes, where PBS and PBA chains play as isolated guest molecules and urea molecules construct the host channel framework. The coalesced PBS/PBA blends are obtained by fast removing the urea framework and systematically investigated by differential scanning calorimetry, X-ray diffraction, proton nuclear magnetic resonance and Fourier transformation infrared spectrometry. It is demonstrated that PBA chains are co-crystallized into PBS extended-chain crystals in the coalesced blends, while such a phenomenon has not been detected in simply co-solution-blended samples. Though PBA chains could not be totally accommodated in the PBS extended-chain crystals, their co-crystallized content increases with the initial feeding ratio of PBA. Consequently, the melting point of the PBS extended-chain crystal gradually declines from 134.3 °C to 124.2 °C with an increasing PBA content. The PBA chains playing as defects mainly induce lattice expansion along the a-axis. In addition, when the co-crystals are soaked in tetrahydrofuran, some of the PBA chains are extracted out, leading to damage to the correlative PBS extended-chain crystals. This study shows that co-inclusion complexation with small molecules could be an effective way to promote co-crystallization behavior in polymer blends.

Abstract:

Single-phase limited cubic solid solutions Pb1-xAgxS based on PbS with a metal sublattice alloyed with silver are obtained. The maximum relative content of silver in solid solutions Pb1-xAgxS reaches x = 0.15. For the first time the thermal expansion of semiconductor solid solutions Pb1-xAgxS was measured by dilatometry method in the temperature range 295-580 K. Substitution of lead atoms by silver atoms in Pb1-xAgxS leads to a decrease in the coefficient of thermal expansion associated with a change in the anharmonicity of atomic vibrations and a weak increase in the elastic properties. For single-crystal particles PbS and solid solutions Pb1-xAgxS, spatial distributions of the elastic modulus E, Poisson's ratio , and linear compressibility  as a function of the direction (hkl) are found. The reflection spectra of the synthesized powders PbS, Ag2S and Pb1-xAgxS are measured and it is shown that the replacement of lead with silver in PbS is accompanied by an increase in the width of the band gap.

Abstract:

This work studied the morphological, mechanical, and thermal properties of poly(lactic acid) (PLA)/polybutylene succinate (PBS)/ethylene-co-methyl acrylate-co-glycidyl methacrylate (EMA-GMA) ternary blends. The polymer blends were prepared in an internal mixer and then molded into films by compression molding. The results showed that the PLA/PBS blends had immiscible morphology in which the PBS phase was dispersed in PLA matrix as spherical shape. The PBS droplet size increased with increasing PBS content. The fractured surface of PLA/PBS/EMA-GMA blends displayed more small crack of plastic deformations than that of PLA/PBS blends and the fracture behavior of PLA/PBA blends was changed to more ductile fracture when added with EMA-GMA. The addition of EMA-GMA in polymer blends improved the compatibility of two phases. The results of the mechanical properties showed that PBS and EMA-GMA addition improved the strain at break of PLA/PBS and PLA/PBS/EMA-GMA blends, respectively. The incorporation of EMA-GMA had no effect on the melting temperature and degradation temperature of PLA blends. The PLA/PBS/EMA-GMA blends had lower percent crystallinity than that of PLA/PBS blends and most of percent crystallinity decreased with increasing EMA-GMA loading due to its more amorphous structure than PLA and PBS.

Abstract:

Nanocrystal quantum dots (NQDs) show great promise in the advancement of the field of photovoltaics. While the maximum efficiency of conventional solar cell (SC) devices is limited to ∼ 31% (Shockley-Queisser limit), devices based on NQDs may attain a maximal thermodynamic efficiency of 42% through the exploitation of multiple exciton generation (MEG). In this process, several electron- hole pairs are created by the absorption of a single high energy photon, as opposed to the single excitons created in conventional solar cell devices. IV-VI semiconductor nanocrystals (PbS, PbSe) are of particular interest as candidates for the exploitation of MEG due to the narrow band gap, high confinement energies, and long radiative carrier lifetimes observed in these systems. In order to realise the full potential of MEG devices, full characterisation of the optoelectronic properties of the underlying nanoparticles is desirable. While the size-dependent properties of NQDs are well understood, the effects of NQD shape are less so. This thesis investigates the effect of ellipticity on the optoelectronic properties associated with spheroidal NQDs. To this end, a four-band, anisotropic, and radially variant k · p system Hamiltonian is expanded in a planewave basis in order to calculate single-particle eigenenergies and eigenfunctions of colloidal PbSe/PbS core/shell heterogeneous NQDs of varying ellipticity. Many-body effects are accounted for via a full configuration interaction (CI) Hamiltonian, the basis of which is comprised of the single-particle states. Exci- tonic and bi-excitonic corrections are then found by mixing of the basis states. In this manner, such diverse electronic and optical properties as quasi-particle binding energies, momentum matrix elements, and charge carrier lifetimes, both radiative and non-radiative, may be predicted.

Abstract:

Ce travail de recherche consiste à étudier les relations structure-propriétés de mélanges biopolymères à base de poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) et poly(butylène succinate) (PBS). Il est divisé en trois parties. La première partie est consacrée à l'étude des propriétés des mélanges PHBV/PBS préparés par voie fondue en fonction de la composition en termes de morphologie et de propriétés rhéologiques, mécaniques, thermiques et barrières. Les résultats obtenus ont été discutés par rapport aux polymères de base. La deuxième partie est consacrée à la compatibilisation des mélanges PHBV/PBS et l'amélioration des interactions à l'interface. Les effets de l'incorporation de la sépiolite à 5% en masse et du PHBV greffé par de l’anhydride maléique (PHBV-g-MA) à 5% en masse ont été étudiés en termes de changements morphologiques montrant un effet synergique entre le compatibilisant et la nanocharge sur les l’ensemble des propriétés des mélanges PHBV/PBS. Enfin, une étude sur le recyclage a été menée à travers une évaluation des effets du nombre de cycles d'extrusion sur les propriétés des matériaux. Elle révèle qu'après 6 cycles d'extrusion, la dégradation thermo-mécanique du PHBV est significativement réduite en présence du PBS
The main objective of this work was to study the structure-properties relationships of biopolymerblends based on poly (3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) and polybutylene succinate (PBS). The work was devised into three parts. The first part was devoted to the study of the properties of PHBV/PBS blends prepared by melt compounding at different weight ratio in terms of morphology and properties. The results obtained were discussed in terms of properties and compared with the neat polymers. The second part was devoted to the study of compatibility of PHBV/PBS blends aiming to improve the interactions at the interface between the two components. The effects of both sepiolite (5% wt.) and PHBV-g-MA (5% wt.) were studied in terms of properties. The results showed a synergistic effect between the compatibilizer PHBV-g-MA and the nanofiller sepiolite though an increase in thermal, mechanical and rheological properties. The last part dealing with the recyclability of PHBV/PBS through the study of the effects of repeated extrusion cycles on the properties of materials. The results showed that after 6 reprocessing cycles the thermo-mechanical degradation of PHBV is significantly reduced in the presence of PBS

Abstract:

Cannabis-related protective behavioral strategies (PBS) are behaviors used before, during, and/or after using cannabis to reduce its associated harms. Despite the effectiveness of PBS in reducing both cannabis use and negative cannabis-related consequences, few studies have examined whether there are sex and cultural differences in PBS use. In the present study, we compare PBS use across males and females and across five countries. We also examine whether the associations of PBS use with cannabis-related outcomes differ by sex and country. We recruited 1,175 college students (63.3% female; Mage = 20.96, SD = 3.95; 45.1% Freshman, 20.2% Sophomore, 16.6% Junior, 9.7% Senior, 8.4% other) who reported past-month cannabis use from eight universities in five countries (U.S., Spain, Argentina, Uruguay, and the Netherlands) to complete an online survey. The online survey included the Marijuana Use Grid (MUG; Pearson & Marijuana Outcomes Study Team, 2020), Protective Behavioral Strategies for Marijuana scale (PBSM; Pedersen et al., 2016; revised by Pedersen et al., 2017), and Brief-Marijuana Consequences Questionnaire (B-MACQ; Simons et al., 2012). Results of a series of ANOVAs suggested differences across countries on the PBSM total score, F(4, 1,126) = 20.93, p < .001, such that participants in the U.S. (M = 4.53, SD = 1.11) and Spain (M = 4.48, SD = 0.95) endorsed the most frequent PBS use and participants in the Netherlands (M = 3.46, SD = 1.49) endorsed the least frequent PBS use. There were many item-level differences in PBS use across countries with a pattern similar to that for the PBSM total score. Results of a series of independent sample t-tests suggested that females (M = 4.51, SD = 1.11) scored higher than males (M = 4.17, SD =1.09) on the PBSM total score, t(1,123) = -4.88, p < .001, as well as nearly every item. The correlations between PBSM total score and cannabis-related outcomes across gender and countries were mostly in the expected direction: more frequent PBS use was associated with less cannabis use and fewer cannabis-related consequences. These correlations were largest for the U.S. sample. Interestingly, however, the correlation between the PBSM total score and B-MACQ was positive for the Argentina sample and every correlation between the PBSM total score and cannabis-related outcome was positive for the Netherlands sample. The results of the present study suggest there are several gender and cultural differences in the use of cannabis-related PBS. However, future studies are needed to replicate these findings, especially given the relatively small samples for some of the countries in the present study (our smallest sample size was for Uruguay [n = 46]). Gender and cultural differences in PBS use should be considered in developing and tailoring PBS interventions, especially because the PBSM was validated with a U.S. sample and most existing interventions were developed for use with U.S. participants.

Full text

Abstract:

One of the problems in the design a magneto-optic read-write head is determining the light level needed at the data detectors. Figure 1 is a schematic of a typical M-O head in which PBS1 and PBS2 are actually leaky beam-splitters that divert from the main optical path (laser to disk and back) some fraction of the p-polarized (unrotated) light. On the outward path this diverted light reduces the efficiency of the head and, especially from the point of view of writing on the disk, the goal would be to minimize this loss. On the return path the light diverted by PBS 1 goes to the servo detectors to provide focus and track-error signals, and that by PBS2 goes to the data detectors.

Abstract:

Honduras es un país de ingresos medios bajos con un sistema de salud fragmentado y menos de US$100 per cápita por año para satisfacer sus necesidades de salud. En el marco de su compromiso por la Cobertura Universal de Salud (CUS), el gobierno decidió diseñar un Plan de Beneficios en Salud (PBS). El diseño del PBS se realizó en cinco pasos. (1) Un equipo interinstitucional del Ministerio de Salud de Honduras y del Instituto de Seguridad Social definió las características fundamentales del PBS. (2) Aprovechando trabajos previos realizados en el país, se identificó el universo de los potenciales candidatos a inclusión. (3) Se discutieron y operacionalizaron criterios de priorización y reglas de decisión. (4) Se utilizó un enfoque ascendente para costear el PBS, con la baja cobertura actual y con diferentes objetivos de mejora de los niveles de cobertura. (5) Se elaboraron análisis de impacto fiscal y se discutieron caminos alternativos de expansión con el gobierno planteando criterios éticos en el camino hacia la CUS. El PBS resultante incluye 74 intervenciones esenciales de salud. Dadas las restricciones financieras, se sugirió un camino de expansión progresiva, mediante el cual los aumentos marginales en el presupuesto de salud se asignarían al PBS. El diseño de un PBS es un proceso específico a cada contexto; incluye varios pasos que van más allá de la implementación de métodos de evaluación de tecnologías sanitarias y requiere mucho tiempo de trabajo técnico y participativo y un pragmatismo sustancial para adaptar las recomendaciones técnicas de la literatura a los datos y a las restricciones de tiempo sobre el terreno.

Abstract:

En este documento se realiza un estudio de caso del plan de beneficios de República Dominicana siguiendo la metodología empleada en el libro "Planes de Beneficios en salud de América Latina: Una comparación regional" (Giedion, Tristao y Bitrán, 2014), donde se estudiaron los Plan Básico de Salud (PBS) de siete países de la región. El documento se estructura a partir de la misma guía aplicada en estos estudios de caso de los otros países (Giedion, Raciborska y Bitrán, 2010), con algunos ajustes para plasmar mejor las particularidades del PBS en la República Dominicana. Se inicia con una descripción del contexto, en la que se detallan las principales instituciones del sistema de salud y sus funciones. Continúa una exposición del proceso histórico de cómo se dio la adopción del plan. Luego se describen, desde distintos ámbitos, las características del mismo para pasar a los métodos de priorización y costeo que ha tenido el PBS dentro del sistema de salud. Luego se revisa cómo ha sido la implementación del recomendaciones que emergen del estudio de caso.

Abstract:

This report, prepared for The Jim Henson Company, shares findings of a sub-study investigating the types of support parents and caregivers need when navigating and using the second-screen Splash and Bubbles for Parents app. This study originated from a prior field study finding indicating families would benefit from support around the app since it represents a new kind of digital tool. In partnership with local Public Broadcasting Service (PBS) stations, we provided parents and caregivers more detailed support around the features of the app. Based on survey and interview findings, parents and caregivers found the app helpful for supporting their children’s science learning, thus validating the field study findings. We also found that all sections of the app were used and could help promote conversations between parent/caregiver and child. Moreover, families expressed choosing to use a specific app section when they felt it was more relevant or developmentally appropriate for their child.
