| Leaves scattered on the parks, passages, and other places have a detrimental effect on the beauty of the environment, and decrease photosynthesis, hence, the efficiency of plants. Leaves are also used in the production of peat. This makes using leaves collectors in parks, and organizations with a green space useful. Due to the fact that leaves take up a high volume, their transportation is difficult. Using the machine introduced in this paper which was equipped with a suction-blower system, increases efficiency, and at the same time decreases the costs of green space, and their workforce cost. Focusing on overcoming the mentioned difficulties, this study was carried out in order to design and produce a tractor powered leaves collector equipped with... |

| In this study, the rate of microwave drying method kiwifruit (Hayward variety) was studied. Samples in a completely randomized design with three different thicknesses of 4, 6 and 8 mm and weight of 15 g and three power of 200, 300 and 400W, with three replications, were dried in the microwave dryer. The samples were weighed every 30 seconds, and then moisture ratio was obtained. According to the results of experiments with different thicknesses Kiwifruit by increasing power, drying time decreased. The amount of effective moisture diffusion coefficient of kiwifruit slices with thickness of 4, 6 and 8 (mm), 3.25×10-9 to 6.49×10-9 (m2/s) and 3.65×10-9 to 1.83×10-8 (m2/s) and 1.29×10-8 to 3.25×10-8 (m2/s) was changed. The value of the effective activation... |

| Microbial fuel cell (MFC) technology is a promising bio-technology that utilizes the microorganism in organic wastes to generate electricity. Although human urine has been identified as a suitable substrate in MFCs, its possible utilization in a soil-based Membrane-less Single Chamber Microbial Fuel Cell (MSCMFC) for constant power generation has, hitherto, not been reported. In this study, a MFC was set up with mud as inoculums in a plastic cylindrical vessel using carbon felt electrodes. It was operated for 19 days (456 hours) without extra substrate. Then, the MFC was treated with human urine (as substrate) four times (Days 19, 24, 32 and 36) each time the MFC output stabilized across external loads. A control MFC (MFCcontrol) was made the same way and... |

| Sisvar is a statistical analysis system with a large usage by the scientific community to produce statistical analyses and to produce scientific results and conclusions. The large use of the statistical procedures of Sisvar by the scientific community is due to it being accurate, precise, simple and robust. With many options of analysis, Sisvar has a not so largely used analysis that is the multiple comparison procedures using bootstrap approaches. This paper aims to review this subject and to show some advantages of using Sisvar to perform such analysis to compare treatments means. Tests like Dunnett, Tukey, Student-Newman-Keuls and Scott-Knott are performed alternatively by bootstrap methods and show greater power and better controls of experimentwise... |

| Esta investigación hace un análisis en torno a la identidad, a partir de una vivencia concreta: Proyecto de empoderamiento (2004). Tiene los objetivos de conocer el vínculo que se establece entre el empoderamiento de las mujeres y los cambios que se suscitan en su identidad así como conocer desde su discurso, los cambios que ellas detectan en su identidad (autoreconocimiento, autoconcepto, autoestima). Se buscó determinar que el proyecto de Empoderamiento de Mujeres, 2004, en Celaya, Gto. ha influido para promover cambios en la identidad de las siete mujeres que participaron, en el plano personal, familiar y comunitario. Las técnicas utilizadas fueron: observación, entrevista, relato de vida, test Machover, test htp y test de la familia. El... |

| Las pruebas de no-inferioridad para comparar proporciones son frecuentemente empleadas en los ensayos clínicos con el objeto de verificar si hay evidencia muestral de que un tratamiento nuevo no es significativamente inferior en eficacia al tratamiento estándar, donde el tratamiento nuevo presenta algunas ventajas sobre el tratamiento estándar como por ejemplo: tener menos efectos secundarios, ser más barato o ser más fácil de aplicar. Un buen número de pruebas de no-inferioridad se han reportado en la literatura. Desafortunadamente, las comparaciones de las pruebas de no inferioridad reportadas hasta ahora son insatisfactorias pues se han realizado utilizando simulaciones o aproximaciones gruesas. Utilizando el concepto de “potencia media”, Martín-Andrés... |

| The need to develop successful collaborative strategies is an enduring problem in sustainable resource management. Our goal is to evaluate the relationship between information networks and conflict in the context of collaborative groundwater management in the rapidly growing central highland region of Arizona. In this region, water-management conflicts have emerged because of stakeholders’ differing geographic perspectives and competing scientific claims. Using social network analyses, we explored the extent to which the Verde River Basin Partnership (VRBP), which was charged with developing and sharing scientific information, has contributed to collaboration in the region. To accomplish this, we examined the role that this stakeholder... |

| A social-ecological system (SES) framework increasingly underpins the “resilience paradigm.” As with all models, the SES comes with particular biases. We explore these key biases. We critically examine how the SES resilience literature has attempted to define and analyze the social arena. We argue that much SES literature defines people’s interests and livelihoods as concerned primarily with the environment, and thereby underplays the role of other motivations and social institutions. We also highlight the SES resilience literature’s focus on institutions and organized social units, which misses key aspects of social diversity and power. Our key premise is the importance of inter- and multi-disciplinary perspectives.... |

| Significant and growing concerns relating to global social and environmental conditions and processes have raised deep questions relating to the ability of traditional governance regimes to manage for the complexities of social-ecological systems. The resilience framework provides a more dynamic approach to system analysis and management, emphasizing nonlinearity, feedbacks, and multiscalar engagement along the social-ecological nexus. In recent years, however, a number of scholars and practitioners have noted various insufficiencies in the formulation of the resilience framework, including its lack of engagement with the dimensions of power within social-ecological systems, which blunt the analytical potential of resilience and run the risk of undermining... |
