No full textMesin planer kayu atau biasa disebut juga mesin serut kayu merupakan mesin pembersih permukaan kayu agar menjadi lebih rata atau lebih halus, mesin planer biasanya digunakan dalam sekala kecil maupun juga skala yang lebih besar atau skala industri. Dalam pengembangan mesin planer yang telah dibuat sebelumnya diperlukan penambahan conveyor yang digunakan sebagai pembawa bahan baku yaitu kayu sehingga lebih efisien dalam proses produksinya.Metode yang digunakan meliputi studi literatur, studi lapangan, proses perancangan serta proses manufaktur. Pada hasil penelitian telah dibuat, conveyor pada mesin planer kayu dengan sistem penggerak motor stepper didapatkan hasil perbedaan kecepatan conveyor tanpa beban dan dengan beban sebesar 0,025 – 0,014 m/detik

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Rhizosphere microbiota drives biogeochemical arsenic transformations in rice paddies amended with sulfate
No full textSubmerged rice paddies are affected by arsenic release into the pore-water from iron (oxy)hydroxides dissolution, with subsequent uptake by the plant and translocation to the grains and specific limits for inorganic arsenic content in rice grains have been established by the European Union. These regulations do not take into account thiolated inorganic and organic arsenics, recognized to be toxic and that have been recently demonstrated to be transported to rice plants. The mechanisms and contribution of biotic and abiotic factors are still poorly characterized. In this study, the role of the rhizosphere microbiota on arsenic concentration and speciation in rice paddies and grains was assessed. Open air mesocosms were set up with rice plants cultivated in soils with different carbon content and sulfate fertilization. Rhizosphere soil and pore-water microbiomes were characterized by monitoring the main physic-chemical parameters and by 16S rRNA genes Illumina sequencing over rice growing season. Phylogenetic and functional genes related to arsenic, sulfur and iron metabolisms were quantified by real-time quantitative PCR. According to Illumina libraries, in all mesocosms, microbiotas in rhizosphere soil and in pore-water differed greatly in terms of both phylogenetic composition and relative abundances. Within the same compartment, soil type mainly drove bacterial and archaeal diversity whereas sulfate amendment did not. However, within the rare biosphere, sulfate fertilization promoted sulfate-reducing, sulfur-oxidizing, arsenate-reducing and arsenite-methylating microorganisms. These results related to a proportional increase of methylated arsenic species in the pore-water and in rice grains, and total arsenic decrease in the medium-carbon soil. These findings indicate a strong link between sulfur- and arsenic-cycling mediated by rice rhizosphere microbiota, with essential implications on revision of possible strategies to deal with arsenic contamination in rice

Naturbaserte løsninger i kommunale planer
No full textProsjektleder: Ingvild Skumlien FurusethNaturbaserte løsninger (NBL) har fått økende oppmerksomhet som en løsning for å håndtere ulike samfunnsutfordringer, deriblant effekter av klimaendringer. Rapporten er basert på et oppdrag for Miljødirektoratet om å undersøke om, i hvilken grad og på hvilken måte føringen om naturbaserte løsninger for klimatilpasning i Statlige planretningslinjer for klima- og energiplanlegging og klimatilpasning (SPR klima) følges opp i samfunns- og arealplanleggingen i utvalgte norske kommuner. For å undersøke dette har vi gjennomført dokumentanalyser, workshop og intervjuer med fire norske kommuner: Bodø, Indre Østfold, Stavanger og Trondheim. Rapporten gir en oversikt over status fra hver kommune og hvordan NBL er vurdert der. Barrierer, muligheter og behov identifisert i oppdraget presenteres, samt eksempler på hvordan NBL kan vurderes. Funnene viser at de fire kommunene har erfaring med NBL, men flere opplever at de fortsatt er tidlig i prosessen. Alle kommunene vurderer og inkluderer bruk av ulike typer NBL i overordnede planer, mens det varierte mer om kommunene også gjorde dette på reguleringsnivå. Knyttet til klimatilpasning vurderes NBL oftest i sammenheng med overvannshåndtering og flom, og i liten grad for andre klimautfordringer. Det kom også frem at informantene generelt var usikre på hvordan vurderinger og begrunnelser i henhold til føringen i SPR klima kan gjennomføres og dokumenteres.MiljødirektoratetpublishedVersio
Simulation of thermal plant optimization and hydraulic aspects of thermal distribution loops for large campuses
No full textFollowing an introduction, the author describes Texas A&M University and its utilities system. After that, the author presents how to construct simulation models for chilled water and heating hot water distribution systems. The simulation model was used in a $2.3 million Ross Street chilled water pipe replacement project at Texas A&M University. A second project conducted at the University of Texas at San Antonio was used as an example to demonstrate how to identify and design an optimal distribution system by using a simulation model. The author found that the minor losses of these closed loop thermal distribution systems are significantly higher than potable water distribution systems. In the second part of the report, the author presents the latest development of software called the Plant Optimization Program, which can simulate cogeneration plant operation, estimate its operation cost and provide optimized operation suggestions. The author also developed detailed simulation models for a gas turbine and heat recovery steam generator and identified significant potential savings. Finally, the author also used a steam turbine as an example to present a multi-regression method on constructing simulation models by using basic statistics and optimization algorithms. This report presents a survey of the author??s working experience at the Energy Systems Laboratory (ESL) at Texas A&M University during the period of January 2002 through March 2004. The purpose of the above work was to allow the author to become familiar with the practice of engineering. The result is that the author knows how to complete a project from start to finish and understands how both technical and nontechnical aspects of a project need to be considered in order to ensure a quality deliverable and bring a project to successful completion. This report concludes that the objectives of the internship were successfully accomplished and that the requirements for the degree of Degree of Engineering have been satisfied
