ABSTRACT: The production of a documentary video in a graduate seminar offers advantages over the traditional term paper. These advantages derive from the nature of the videotape medium. The most distinct difference between a written document and a video production is the use of the video camera to record events. In using the camera, the student is required to become involved both in front of the video camera, for example, as an interviewer, and behind the camera as a camera operator. Next, as an editor, the student is required to review the events that she/he has taped for inclusion in the final product. By participating in these three roles, the student has the opportunity to learn interviewing skills while interacting with professionals in the field, to learn videotaping skills, and to see him/herself as he/she appears to others. The student can use the video feedback to improve his/her professional presentation;posture, dress, gestures, speech, and facial expressions all have an impact on how we are perceived by others. Additionally, the painstaking process of reviewing the taped material leads to an intimate knowledge of the topic, and the process of choosing portions out of entire interviews hones the ability to select the crucial or central themes and ideas from any discussion. Finally, the power of video lies in its ability to communicate information to a wide audience. Although the nature of video for the general public does not permit highly detailed or rigorous coverage of any topic, it is a major source of information. Accordingly, video is an important tool that can be used to inform the public about the importance of wise water resource management. Copyright © 1987, Wiley Blackwell. All rights reserved

The study aims to assess the effect of small scale irrigation adoption to farmers in Nasho sector, Kirehe District in Rwanda. The average yield was 12,309.73 Kg/2.62 ha or 4698.73 Kg/ha for adopters with the mean difference between adopters and non adopters ranged from 2819.63 Kg to 4766.59 Kg per unit area of production. For food security status, the average mean quantity of maize consumed at home level was 615.54 Kg with the mean difference ranged from 377.29 Kg to 474.68 Kg. For market participation, the average treatment effect of the treated (ATT) of quantity of maize sold was 11,694.24 Kg while the mean difference ranged from 7165.98 Kg to 9015.60 Kg. The Average Treatment Effect of the Treated market price was 213 Frws/Kg while the mean difference ranged from 44.51 Frws/Kg to 48.3053 Frws/Kg. The Average Treatment Effect of the Treated of farmer’s revenues for the users was 938,772 Frws/ha, however, the mean difference between adopters and non adopters ranged from 1,732,942 Frws to 2,007,039 Frws. The Average Treatment Effect of the Treated of farmer’s net farm income was 1,066,393 Frws while mean difference between users and non users ranged from 803,967 Frws to 854,141 Frws. For profitability analysis, the cost benefit ratio (CBR) was taken into account. The total benefit per unit area was 2,434,509 Frws and total average mean cost of 1,382,313 Frws and CBR = 1.761 > 1. The findings of this study will help the policy makers for deeper sector planning and also, it will facilitate other stakeholders to invest in irrigation technology to improve the livelihoods of Rwandan farmers and other surroundings.

Tropical forests and woodlands are key components of the global carbon and water cycles. Yet, how climate change affects these biogeochemical cycles is poorly understood because of scarce long-term observations of tropical tree growth. The recent rise in tropical tree-ring studies may help to fill this gap, but a large-scale quantitative analysis of their potential in global change research is missing. We compiled a list of all tropical tree species known to form annual tree rings and built a network encompassing 492 tropical ring-width chronologies to evaluate the potential to generate insights on climate sensitivity of woody productivity and to build centuries-long reconstructions of climate variability. We assess chronology quality, length, and climatic representativeness and explore how these change along climatic gradients. Finally, we applied species-distribution modeling to identify regions with potential for tree-ring studies in ecological and climatic studies. The number of tropical chronologies has rapidly increased, with ∼400 added over the past two decades. Yet, tree-ring studies are biased towards high-elevation locations, with gaps in warmer and wetter climates, on the African continent, and for angiosperm species. The longest chronologies with strongest climate signals (i.e., synchronous growth variations among trees) are from cool regions. In wet regions, climate signals and precipitation sensitivity decrease. Most tropical regions harbor 5–15 (and up to 80) species with proven potential to generate chronologies. The potential for long climate reconstructions is particularly high in drier high elevation sites. Our findings support strategies to effectively expand tree-ring research in the tropics, by targeting specific species and regions. Tropical dendrochronology can importantly contribute to global change research by generating historical context of climate extremes, quantifying climate sensitivity of woody productivity and benchmarking vegetation

Case Studies in Chemical and Environmental engineering 2024年 10卷

作者： Sofyana Muslim, Abrar Supardan, Muhammad Dani Ambarita, Aulia Chintia Arahman, Nasrul Doctoral Program School of Engineering Science Syiah Kuala University Department of Chemical Engineering Syiah Kuala University Graduate School of Environmental Management Universitas Syiah Kuala Research Center for Environmental and Natural Resources Universitas Syiah Kuala Oil Palm and Coconut Research Center Universitas Syiah Kuala

The effectiveness of polyvinylidene fluoride (PVDF) membranes in various applications is often hampered by fouling, necessitating the exploration of modification strategies to enhance their antifouling properties. This study investigates the effect of combining cellulose nanocrystal (CNC) and graphene oxide (GO) on PVDF membranes to address this issue. Six flat sheet membranes with different compositions were fabricated using a non-solvent-induced phase separation method. The resulting membrane (M5: CNC 1 % w/w and GO 0.25 % w/w) exhibited increased surface pores, a finger-like cross-sectional structure, and higher water content. The pure water flux (PWF) in the M5 membrane increased to 37 L/m²∙h, with a humic acid (HA) rejection rate of 60 % and excellent antifouling properties (98.32 %). In conclusion, this study successfully modified PVDF membranes by combining CNC and GO, resulting in membranes with improved properties and performance. The present study provides valuable insights into composite membrane design and offers potential solutions to fouling challenges. © 2024 The Authors

Cloud computing is evolved from grid computing with a key support from the rapidly expanding virtualization technology. We argue that clouding computing is particularly suitable for supporting emergency response and management (ERM) because of some of its unique features such as rapid setup and deployment on ad hoc basis, highly flexible platforms (PaaS: Platform as a Service) and application services (SaaS: Software as a Service) with little time-space constraints. ERM is one of the seven critical national infrastructures and services mandated to protect by the 1999 US President's Executive Order (PCCIP). The paradigm of survivability and survivable network systems was a response of academia to the president's executive order. We concur that survivability should be the lifeline of any ERM, including the cloud computing supported (CCS) ERM systems. In this article, we present a research agenda that is aimed at developing a survivability-centered architecture for evolving reliable and survivable CCS-ERM systems. The research agenda suggests that biological and computational evolutions should be rich sources of biological inspirations as well as powerful optimization algorithm for designing (evolving) the ERM systems. The proposed research agenda advocates the application of three-layer survivability analysis, dynamic hybrid fault models, and extended evolutionary game theory modeling developed by Ma & Krings [Ma & Krings (2008a-e, 2011), Ma et al. (2009a), Ma (2008, 2009, 2010, 2011a,b). We use banking system survivability as an example to illustrate the proposed research agenda.

Estimating carbon footprint (CF) of rice production could administer an insight into the input of rice production to climate change and analysing possible greenhouse gas (GHG) alleviation alternatives. In this study, data for the rice production of 34 provinces in Indonesia at year of 2015 were gathered from the Indonesian statistical data on area cultivation, productivity, fertilizer application, diesel, and irrigated water. The CF of indirect and direct carbon emissions which were correlated with those agricultural intakes was calculated with reported emission factors. The result demonstrated the CFs mean in 34 provinces during dry and rainy season in Indonesia was 1,900,341.48 kg CO eq/ha and 1,892,825.68 kg CO eq/ha, respectively. The data also showed that the highest of CF production during dry and rainy seasons obtained by Belitung Islands and East Nusa Tenggara province, respectively. Meanwhile the lowest of CF production for both dry and rainy season belonged to Yogyakarta province. Result on the quantified agricultural intakes demonstrated the irrigation water usage, fertilizer usage, direct methane and diesel for agricultural tools, had biggest to lowest contribution to CF production, respectively. Based on the result, we concluded that a rice cultivation practices which has an efficient irrigation water usage may become an option to reduce CF that leads to climate change mitigation.
