The World Wide Web is revolutionizing the way that researchers access scientific information. Articles are increasingly being made available on the homepages of authors or institutions, at journal Web sites, or in online archives. However, scientific information on the Web is largely disorganized

Molluscicidal effect of biogenic silica and botanical pesticides for the control of Achatina fulica (giant African land snail) and Laevicaulis alte (garden slug)

Abstract Article Information Declining soil fertility is one of the major problems causing yield reduction of barley in Southwestern Ethiopia. Therefore, field experiments were, carried out at Adiyo and Ghimbo districts, Kaffa Zone, Southwestern Ethiopia, to determine the effects of combined application of farm yard manure (FYM) and vermi compost (VC) with inorganic NP on growth, yield and yield components of food barley. The treatments included combinations of two rates (2.5 and 5 t ha-1) of FYM and two rates (2.5 and 5 t ha-1) of VC with 25%, 50% and 75 % of recommended rates of inorganic NP, respectively. In addition, 100% recommended rate of inorganic NP (23 kg N ha-1 and 46 kg P2O5 ha-1) and zero rates were used for comparison. The experiments were laid out in a randomized complete block design with three replications. The results revealed that applying 5 t ha-1 FYM combined with 75 % inorganic NP gave the highest number of productive tiller m-2 (227 and 215) and grain number spike-1 (37 and 36.7) and grain yield (3668 and 3486 kg ha-1) of barley at Adiyo and Ghimbo, respectively. The application of 5 t ha-1 FYM in combination with 75% inorganic NP has increased grain yield by 69.30 % and 43.45 % at Adiyo and by 66.86 % and

Comparative study on damage index evaluation for new and existing reinforced concrete structures

In this work we aim to deal with so-called “shelf architecture ” – drawings which were never built three dimensionally in the physical world, except maybe in models, but not to be inhabited. Today the digital methods build a possibility to rebuild the past, but also to explore the future this way. We first analysed three utopias, one by Mies van der Rohe and two by Frank Lloyd Wright. In the second part we propose ourselves an utopia. All are skyscrapers, for which reason the load bearing structure was relevant at the moment of design, unlike for the virtual world, for which we build such a model at the end. Rezumat În această lucrare tratăm subiectul aşa numitei „arhitecturi de sertar ” – desene care nu au fost niciodată construite tridimensional în lumea fizică, decât poate în machete, dar nu pentru a fi locuite. Astăzi metodele digitale oferă posibilitatea de a reconstrui trecutul, dar şi de a explora viitorul în acest fel. Am analizat întâi trei utopii, una de Mies van der Rohe şi două de Frank Lloyd Wright. În a doua parte propunem noi înşine o utopie. Toate utopiile sunt pentru zgârie-nori, din care motiv structura portantă este relevantă în momentul proiectării, lucru care nu este valabil pentru lumea virtuală, pentru care am construit o astfel de machetă în final.

Nowadays environmental problems are more and more significant. The industrial area produces lots of waste materials and CO2, respectably. One of the most effective ways to solve these problems is the utilization of these waste materials. One choice of the usage of the waste materials is in the construction industry. The most common and widely used building material is concrete. Scientists and engineers are continuously working for better concrete properties from strength to durability standpoint with the help of innovative chemical admixtures and supplementary cementing materials. Waste materials are used as replacement of common aggregates or cements. The most significant and indispensable part of concrete is cement. The production process of cements from its raw material produces a lot CO2. The most effective way to decrease the CO2 emission of cement industry is the substitution of a proportion of cement with supplementary cementing materials (SCM’s). SCM’s are often used in concrete mixes to reduce cement contents, improve workability, increases strength and enhanced durability through hydraulic or pozzolanic activity. Utilization of these- usually industrial- by-products in cement/mortar/concrete not only prevents them from being land-filled but also enhances the properties of concrete in the fresh and hardened states.
