Analytical technique characterizes all trace contaminants in water

Properly programmed combination of advanced chemical and physical analytical techniques characterize critically all trace contaminants in both the potable and waste water from the Apollo Command Module. This methodology can also be applied to the investigation of the source of water pollution

In this report I will particularly focus on the design process and the design product

The changing tide: Federal support of civilian-sector R and D

The involvement of the Federal government in civilian sector research and development is discussed. Relevant policies are put in an historical perspective. The roles played by industrial research and public funding are reveiwed. Government support of basic an generic research, clientele-oriented applied research, and research with commercial ends is studied. Procurement, anti-trust, and patent policies, all of which affect the climate for private research and development, are examined

Implementasi Mendukung Ketahanan Pangan melalui Kegiatan M-krpl di Kota Kupang Nusa Tenggara Timur

Sustainable food house area (KRPL) is a governmental program to drive economy to maximize fulfillment of farmer's food need. It was early introduced by Agricultural Ministry in Kayen Village, Pacitan, East Java by President Susilo Bambang Yudhoyono and then was developed by Agricultural Research agency in Indonesia by BPTP. Target area is yard. Kupang is one of town in NTT doing the activity. The objective of the research was to identify implementation of KRPL model in Kupang, to evaluate performance of technology component in KRPL activity and to identify obstacle and continuity of the program. The research was conducted in Kupang for six months from July–December 2013. The results indicated that the program was implemented in six areas (three military areas and three civil areas) with good results indicated with various plants cultivated such as horticulture, medicinal plant and ground fishery. Performance of component application has run as planned step from dissemination, preparation and realization (polybag filling, planting, transferring, keeping, harvest and post harvest). The dominant obstacles is water

Analisis USAha Panen Cengkehdi Kabupaten Minahasa Tenggara Propinsi Sulawesi Utara

Currently, clove is important plantation crop due to its high price (Rp 85.000 at harvest and Rp 135.000 at dry condition), although at late 1990s it was only Rp 3500 per kg. Then, many clove crops were left died with bad cultivation, cut, and even made as firewood. In relation to free trade area, clove cigarette development, great cigarette excise and source of employment, government gives increasingly great attention. Then, as main commodity of national economy, clove cultivation is important matter included harvest and post harvest process because it will affect quality and selling price. Objectives of the research was to study cost structure of harvest and post harvest, to identify harvest and post harvest cost effect on income, and to analyze feasibility of clove cultivation business. The research was done for 2 months from August to September 2013. Location was determined using purposive sampling involving 20 farmers. Data include primary and secondary data that was analyzed descriptively. The results indicated that harvest cost was very high covering 80.33% of total cost in clove cultivation cost; harvest and post harvest cost has effect of 20.92% on revenue and 26.46% on income. This clove cultivation is feasible financially because it is economically profitable with B/C ratio of 3.77. Keywords: clove, farming system, price, labour, farme

Cornering the unphysical vertex

In the classical pure spinor worldsheet theory of AdS5xS5 there are some vertex operators which do not correspond to any physical excitations. We study their flat space limit. We find that the BRST operator of the worldsheet theory in flat space-time can be nontrivially deformed without deforming the worldsheet action. Some of these deformations describe the linear dilaton background. But the deformation corresponding to the nonphysical vertex differs from the linear dilaton in not being worldsheet parity even. The nonphysically deformed worldsheet theory has nonzero beta-function at one loop. This means that the classical Type IIB SUGRA backgrounds are not completely characterized by requiring the BRST symmetry of the classical worldsheet theory; it is also necessary to require the vanishing of the one-loop beta-function.Comment: LaTeX 40pp; v2: explained the relation to the linear dilaton background (Section 6), changes in Introduction and Abstrac

Event-Driven Network Programming

Software-defined networking (SDN) programs must simultaneously describe static forwarding behavior and dynamic updates in response to events. Event-driven updates are critical to get right, but difficult to implement correctly due to the high degree of concurrency in networks. Existing SDN platforms offer weak guarantees that can break application invariants, leading to problems such as dropped packets, degraded performance, security violations, etc. This paper introduces EVENT-DRIVEN CONSISTENT UPDATES that are guaranteed to preserve well-defined behaviors when transitioning between configurations in response to events. We propose NETWORK EVENT STRUCTURES (NESs) to model constraints on updates, such as which events can be enabled simultaneously and causal dependencies between events. We define an extension of the NetKAT language with mutable state, give semantics to stateful programs using NESs, and discuss provably-correct strategies for implementing NESs in SDNs. Finally, we evaluate our approach empirically, demonstrating that it gives well-defined consistency guarantees while avoiding expensive synchronization and packet buffering

Spin-charge-lattice coupling near the metal-insulator transition in Ca3Ru2O7

We report x-ray scattering studies of the c-axis lattice parameter in Ca3Ru2O7 as a function of temperature and magnetic field. These structural studies complement published transport and magnetization data, and therefore elucidate the spin-charge-lattice coupling near the metal-insulator transition. Strong anisotropy of the structural change for field applied along orthogonal in-plane directions is observed. Competition between a spin-polarized phase that does not couple to the lattice, and an antiferromagnetic metallic phase, which does, gives rise to rich behavior for B $\parallel$ b.Comment: 6 pages, 4 figures, to appear in Phys.
