Monolithic microwave integrated circuit water vapor radiometer

A proof of concept Monolithic Microwave Integrated Circuit (MMIC) Water Vapor Radiometer (WVR) is under development at the Jet Propulsion Laboratory (JPL). WVR's are used to remotely sense water vapor and cloud liquid water in the atmosphere and are valuable for meteorological applications as well as for determination of signal path delays due to water vapor in the atmosphere. The high cost and large size of existing WVR instruments motivate the development of miniature MMIC WVR's, which have great potential for low cost mass production. The miniaturization of WVR components allows large scale deployment of WVR's for Earth environment and meteorological applications. Small WVR's can also result in improved thermal stability, resulting in improved calibration stability. Described here is the design and fabrication of a 31.4 GHz MMIC radiometer as one channel of a thermally stable WVR as a means of assessing MMIC technology feasibility

Rancang Bangun Sistem Distribusi Hasil Produksi Obat untuk Menjamin Kualitas dalam Meningkatkan Pelayanan Pelanggan

Pharmaceutical companies in Indonesia that are engaged in manufacturing currently continue to develop, they process medicinal ingredients into pharmaceuticals, such as tablets, syrup, capsules and others. At present the distribution and production management system of drugs is still semi-computerized, because it still uses Ms. Excel, which can cause file-to-file buildup, besides that it is possible that the data will be lost or damaged, and when searching for data, it takes a long time. To overcome this need to be built a system to process the drug distribution and production management system, to help companies more easily access drug data to computerized travel documents, so as to increase the effectiveness and time efficiency, and get maximum work results and data accuracy in data input in the relevant section. It certainly can be found with various methods that use penuls, starting from the use of uml to provide an overview of system design, then MySql as a data processing application in thedatabase, as a programming language using php

Shoot Tip Culture of Nepenthes Albomarginata Lobb Ex Lindl. in Vitro

Kultur Pucuk Tanaman Nepenthes albomarginata Lobb ex Lindl. secara In Vitro. N. albomarginata adalah kantong semar kerah putih (white collared pitcher plant), salah satu tanaman pemakan serangga yang sangat menarik sebagai tanaman hias. Tanaman ini terancam punah karena pengambilan dan kerusakan habitatnya. Penelitian perbanyakan secara in vitrodilakukan dengan menggunakan pucuk tanaman N. albomarginata pada media formulasi setengah Murashige and Skoog (1/2 MS) dengan tambahan zat pengatur tumbuh 6-benzyladenine (BA) 1 mg l-1 dengan atau tanpa kombinasi dengan á-naphthalene acetic acid (NAA) atau 4 amino 3,5,6, trichloropicolinic acid (Picloram) 0.5, 1, 1.5, and 2 mg l-1. Perlakuankombinasi BA 1 mg l-1 dengan NAA 0.5 mg l-1 menghasilkan pertambahan tinggi tanaman terbesar. Tanaman menghasilkan jumlah daun terbanyak pada kontrol. Perlakuan BA 1 mg l-1 menumbuhkan tunas aksilar terbanyak, sedangkan kombinasinya dengan NAA 1.5 mg l-1 merupakan perlakuan yang dapat menghasilkan tunas adventif. Kombinasi BA 1 mg l-1 dan NAA 2 mg l-1 menginduksi kalus terbaik. Tanaman yang dihasilkan belum membentuk akar, tetapi pertumbuhan lebih lanjut dapat membentuk perakaran dan dapat hidup di luar botol kultur setelah diaklimasi

Dynamics of Crust Dissolution and Gas Release in Tank 241-SY-101

Due primarily to an increase in floating crust thickness, the waste level in Tank 241-SY-101 has grown appreciably and the flammable gas volume stored in the crust has become a potential hazard. To remediate gas retention in the crust and the potential for buoyant displacement gas releases from the nonconvective layer at the bottom of the tank, SY-101 will be diluted to dissolve a large fraction of the solids that allow the waste to retain gas. The plan is to transfer some waste out and back-dilute with water in several steps. In this work, mechanisms and rates of waste solids dissolution and gas releases are evaluated theoretically and experimentally. Particular emphasis is given to crust dissolution processes and associated gas releases, although dissolution and gas release from the mixed-slurry and nonconvective layers are also considered. The release of hydrogen gas to the tank domespace is modeled for a number of scenarios. Under the tank conditions expected at the time of back-dilution, no plausible continuous or sudden gas release scenarios resulting in flammable hydrogen concentrations were identified
