Open Journal of Soil Science (OJSS) , 2014, DOI: 10.4236/ojss.2014.413046
Abstract:

The paper is based on a study whose objective is to provide an understanding of the extent to which traditional knowledge and indigenous institutions for natural resource governance remain relevant to solving current land degradation issues and how they are integrated in formal policy process in Kilimanjaro Region. Data collection for this study combined qualitative and quantitative methods. A total of 221 individuals from households were interviewed using a structured questionnaire; 41 in-depth interviews and 24 focus group discussions were held. Findings indicate that the community acknowledges that there is traditional knowledge and indigenous institutions regarding sustainable land management. However, awareness of the traditional knowledge and practices varied between districts. Rural-based districts were found to be more aware and therefore practiced more of traditional knowledge than urban based districts. Variations in landscape features such as proneness to drought, landslides and soil erosion have also attracted variable responses among the communities regarding traditional knowledge and indigenous practices of sustainable land management. In addition, men were found to have more keen interest in conserving the land than women as well as involvement in other traditional practices of sustainable land management. This is due to the fact that, customarily, it is men who inherit and own land. This, among other factors, could have limited the integration of traditional knowledge and indigenous institutions in village by-laws and overall policy process. The paper concludes by recommending that traditional knowledge and indigenous institutions for sustainable land management should be promoted among the younger generations so as to capture their interest, and ensure that successful practices are effectively integrated into the national policies and strategies.

Abstract: The vertical distribution of ambient biogenic volatile organic compounds (BVOC) concentrations within a hemiboreal forest canopy was investigated over a period of one year. Variability in temporal and spatial isoprene concentrations, ranging from 0.1 to 7.5 μg m 3, can be mainly explained by biogenic emissions from deciduous trees. Monoterpene concentrations exceeded isoprene largely and ranged from 0.01 to 140 μg m 3 and during winter time anthropogenic contributions are likely. Variation in monoterpene concentrations were found to be largest right above the ground and the vertical profiles suggest a weak mixing leading to terpene accumulation in the lower canopy. Exceptionally high values were recorded during a heat wave in July 2010 with very high midday temperatures above 30 °C for several weeks. During summer months, monoterpene exceeded isoprene concentrations 6-fold and during winter 12-fold. During summer months, dominance of α-pinene in the lower and of limonene in the upper part of the canopy was observed, both accounting for up to 70% of the total monoterpene concentration. During wintertime, Δ3-carene was the dominant species, accounting for 60% of total monoterpene concentration in January. Possible biogenic monoterpene sources beside the foliage are the leaf litter, the soil and also resins exuding from stems. In comparison, the hemiboreal mixed forest canopy showed similar isoprene but higher monoterpene concentrations than the boreal forest and lower isoprene but substantially higher monoterpene concentrations than the temperate mixed forest canopies. These results have major implications for simulating air chemistry and secondary organic aerosol formation within and above hemiboreal forest canopies. Possible effects of in-cartridge oxidation reactions are discussed as our measurement technique did not include oxidant scavenging. A comparison between measurements with and without scavenging oxidants is presented.

Abstract: In models of plant volatile isoprenoid emissions, the instantaneous compound emission rate typically scales with the plant's emission potential under specified environmental conditions, also called as the emission factor, ES. In the most widely employed plant isoprenoid emission models, the algorithms developed by Guenther and colleagues (1991, 1993), instantaneous variation of the steady-state emission rate is described as the product of ES and light and temperature response functions. When these models are employed in the atmospheric chemistry modeling community, species-specific ES values and parameter values defining the instantaneous response curves are often taken as initially defined. In the current review, we argue that ES as a characteristic used in the models importantly depends on our understanding of which environmental factors affect isoprenoid emissions, and consequently need standardization during experimental ES determinations. In particular, there is now increasing consensus that in addition to variations in light and temperature, alterations in atmospheric and/or within-leaf CO2 concentrations may need to be included in the emission models. Furthermore, we demonstrate that for less volatile isoprenoids, mono- and sesquiterpenes, the emissions are often jointly controlled by the compound synthesis and volatility. Because of these combined biochemical and physico-chemical drivers, specification of ES as a constant value is incapable of describing instantaneous emissions within the sole assumptions of fluctuating light and temperature as used in the standard algorithms. The definition of ES also varies depending on the degree of aggregation of ES values in different parameterization schemes (leaf- vs. canopy- or region-scale, species vs. plant functional type levels) and various aggregated ES schemes are not compatible for different integration models. The summarized information collectively emphasizes the need to update model algorithms by including missing environmental and physico-chemical controls, and always to define ES within the proper context of model structure and spatial and temporal resolution.

Case Reports in Clinical Medicine (CRCM) , 2015, DOI: 10.4236/crcm.2015.43021
Abstract:
Alveolar capillary dysplasia with misalignment of pulmonary veins (ACD/MPV) is a rare, fatal developmental lung disorder of neonates and infants, associated with severe persistent pulmonary hypertension unresponsive to treatment. We reported the case of a term newborn with delayed presentation of ACD/MPV and a novel mutation of FOXF1 gene that received supportive cardiopulmonary treatments, inhaled nitric oxide, oral sildenafil and nebulized iloprost with no clinical improvement. DNA sequence analysis of FOXF1 gene identified a novel heterozygous variant c.257G > C; p.R86P, in exon 1. At autopsy, lung histology showed the characteristic features of ACD/MPV. FOXF1 has been identified as one of the genes responsible for ACD/MPV associated with multiple congenital malformations. This is a report of a novel heterozygous variant c.257G > C; p.R86P, in the first exon of FOXF1, in a patient with delayed presentation of ACD/MPV.

Open Journal of Soil Science (OJSS) , 2014, DOI: 10.4236/ojss.2014.413043
Abstract:

In 2012, governments across the world adopted “The Future We Want” outcome document in Rio De Janeiro as a commitment to achieve a land-degradation-neutral world. This document reasserts the importance of sustainable land management in the top of the debates on sustainable development. This paper provides an overview of Tanzania’s preparedness towards achieving these global objectives. The paper is based on a keynote address which was presented in the conference on reducing land degradation on the highlands of Kilimanjaro Region in Tanzania. Using a biogeographical perspective, the paper assesses challenges of adopting programmatic approach to sustainable land management in Tanzania. It also presents some opportunities that exist through Global Mechanism of the United Nations Convention to Combat Desertification, which promote actions leading to coordination, mobilization and channeling of financial resources to assist member countries to coordinate and sustain sustainable land management projects.

South African Journal of Bioethics and Law , 2010,
Abstract: The practice of telemedicine is viewed as a possible solution to the human resources crisis in health care in South Africa and internationally. Reports on its successful implementation and combating of health-related problems are readily available from both developed and developing countries. Even though these reports indicate that telemedicine seems to have addressed the problem related to the shortage of health care personnel, it is still posing a challenge to regulatory authorities such as the Health Professions Council of South Africa. The regulatory authorities are there to ensure that quality health care service is delivered and that the patient will be protected from possible mismanagement by the health care practitioners involved. Misconduct can occur through improper clinical care or excessive billing. Policies and guidelines from both developing and developed countries were reviewed to highlight how telemedicine is regulated elsewhere. The focus was on the ethical implications of telemedicine practice. Telemedicine has proved itself to be a possible solution to the human resources crisis, especially in developing countries or where there are vast rural communities. Success of telemedicine has been reported in a number of developed and developing countries as a way of alleviating the human resources crisis and providing quality health care to needy communities.
Die hormonelle Behandlung transsexueller Personen

Journal für Reproduktionsmedizin und Endokrinologie , 2004,
Abstract: Die psychiatrische Diagnose Transsexualit t wird bei kontrasexuell identifizierten Personen gestellt und stellt die wohl extremste Form einer Geschlechtsidentit tsst rung dar. Neben psychiatrischen und psychotherapeutischen Interventionen sowie der operativen Angleichung an das gewünschte Geschlecht ist die gegengeschlechtliche Hormontherapie ein bedeutender Pfeiler des Behandlungsprozesses. Sie hat weitreichende teils irreversible Konsequenzen. Dieser Beitrag beschreibt die Hormontherapie in der besonderen Indikation "Transsexualit t" unter Berücksichtigung des Kontextes. Die Hormontherapie supprimiert die genuinen, aber unerwünschten sekund ren Geschlechtscharakteristika und induziert, mehr oder weniger ausgepr gt, die Ausbildung der Geschlechtscharakteristika des gewünschten anderen Geschlechts. Die Therapie hat ein erhebliches Risikopotential. Nach der hormonell induzierten u erlichen Angleichung an das gewünschte Geschlecht und der operativen Geschlechtskonversion mu eine Hormontherapie jahre-, manchmal jahrzehntelang fortgesetzt werden. Nicht wenige transsexuelle Personen verzichten nach der operativen Geschlechtsanpassung auf weitere professionelle Betreuung, einerseits aus Sorge vor "Pathologisierung" ihres Zustandes, andererseits aus Unkenntnis über m gliche (Langzeit-) Folgen der hochdosierten gegengeschlechtlichen Hormontherapie. Risikoscreening und Adaption der notwendigen Therapie an das individuelle Risikoprofil, Optimierung von Lifestyle-Faktoren sowie regelm ige Checkups k nnen dazu beitragen, das immanente Risiko der gegengeschlechtlichen Hormontherapie auf ein vertretbares Ma zu senken. Kontrollen erfassen unterschiedliche Bereiche, wie kardiovaskul re Parameter, Lipidprofil, Osteodensitometrie, die Brustdrüse, die Genitalorgane u.v.m., und lassen sich nicht auf einen basalen Hormonstatus von 17β-Estradiol und Testosteron reduzieren. Vorliegende Daten zeigen, da Transsexuelle unter der Voraussetzung einer optimalen Betreuung ein mit der allgemeinen Bev lkerung vergleichbares Morbidit ts- und Mortalit tsrisiko aufweisen. Die Notwendigkeit einer professionellen somatischen Betreuung dieser Personengruppe wird zunehmend erkannt. Die lebenslang notwendige komplexe Behandlung wird am effektivsten durch spezialisierte, interdisziplin r arbeitende Transgender-Teams gew hrleistet.
Flexural and Compressive Strength of Concrete Tiles with Different Levels of Partial Substitution of Pulverized Solid Waste Materials for Gravel  [PDF]

Open Access Library Journal (OALib Journal) , 2015, DOI: 10.4236/oalib.1101187
Abstract: A factorial experiment in completely randomized design with three (3) replications was employed in this study. Gravel was partially substituted with two (2) kinds of pulverized solid waste materials at three (3) levels of substitutions: 15% (LS2) and 30% (LS3) and 45% (LS4). This study had a total of twelve (12) experimental treatment combinations to include a control treatment (LS1 with 0 partial substitution) for purposes of comparison. The results of this study generally showed that the partial substitution of pulverized solid waste material for gravel significantly lowered the flexural and compressive strengths of concrete tiles. The concrete tiles with 15% (LS2) partial substitution had the highest average flexural and compressive strengths, while the tiles with 45% (LS4) partial substitution had the lowest average values. As to the type of solid waste material, the study revealed that the concrete tiles with pulverized clear-plastic solid waste materials had numerically higher flexural and compressive strengths than those concrete tiles with pulverized aluminized plastic solid waste material for gravel. The researchers concluded that the partial substitution of pulverized solid waste materials for gravel significantly lowered the flexural and compressive strengths of the concrete tiles.

Abstract: ResumenLa dinámica de la descomposición y la liberación de nutrientes a partir de los restos vegetales son procesos clave para la fertilidad edáfica, por lo que resultan adecuados para estimar el grado de sustentabilidad de los sistemas productivos. En este trabajo se evaluó el efecto del tipo de desmonte (total y selectivo) sobre la tasa de descomposición, la liberación de N y la fertilidad del suelo de pastizales (nativos e introducidos) para uso ganadero en el Chaco árido de la Provincia de Córdoba, con la finalidad de predecir el grado de sustentabilidad de ambos sistemas productivos bajo las condiciones climáticas de la región. Se utilizó un dise o experimental de parcela dividida: desmonte (total vs selectivo)/pastura (nativa vs introducida), con 4 réplicas por tratamiento.En las parcelas se colocaron jaulas de descomposición con 20 g de residuos (colectados en cada tratamiento) que fueron retiradas al final de cada estación climática durante dos a os. Muestras de suelo (0-20 cm de profundidad) fueron tomadas anualmente en ambos tipos de desmonte y en un bosque colindante como testigo.En cada fecha de muestreo se evaluó el peso y las características químicas y biológicas de los residuos. En las muestras de suelo se determinó el contenido de nitratos, las fracciones de la materia orgánica y la respiración edáfica. Durante el primer a o de estudio, la tasa de descomposición y la mayoría de los parámetros analizadosfueron muy semejantes entre tratamientos. Contrariamente, en el segundo a o todos los valores fueron muy erráticos debido a que germinaron pastos dentro de las jaulas. Los parámetros de fertilidad analizados no mostraron diferencias entre sistemas de desmonte y se correlacionaron con el contenido de humedad. Nuestros resultados indican que: a) las condiciones climáticas del Chaco árido afectan la descomposición en mayor medida que la composición química de los residuos y el tipo de desmonte; b), los cambios en la cantidad y calidad de la materia orgánica del suelo (como resultado del desmonte) comprenden un proceso muy lento (mayor a 3 a os desde el desmonte); y c) la presencia de árboles en los desmontes selectivos favorece la liberación de N a partir de los pastos nativos, lo cual corrobora la importancia de la conservación de la diversidad (le osas y pastos naturales) sobre la sustentabilidad del pastizal en los ambientes áridos.AbastractThe decomposition and nutrient release dynamic from plant residues are key process for soil fertility; therefore they are adequate to estimate the sustainability degree of productive systems.
