Metais pesados em solos de área de rejeitos de indústria de processamento de zinco (1999)

Apesar de a poluição do solo ser amplamente constatada, estudos sobre as concentrações e formas dos metais pesados em solos e seus efeitos no ecossistema são ainda pouco enfatizados, principalmente em condições tropicais. O presente estudo foi desenvolvido em área de rejeitos de uma unidade de extração e industrialização de zinco pertencente à Companhia Mineira de Metais-CMM, em Três Marias (MG), com o objetivo de avaliar as quantidades e formas de metais pesados em sete locais representativos da área. Os locais foram selecionados para amostragem, baseando-se em diferenças na forma de contaminação, aspectos de solo, topografia e vegetação. Realizaram-se análises químicas de fracionamento de metais pesados e extrações simples com DTPA e Mehlich-1, buscando determinar os teores e formas dos metais na superfície e em profundidade e fazer inferências sobre o potencial de risco ambiental desses metais. Os teores totais dos metais nas camadas superficiais dos locais estudados foram, em média, de: 13.533 mg kg-1, para Zn; 170 mg kg-1, para Cd; 865 mg kg-1, para Cu, e 612 mg kg-1, para Pb, enquanto os teores trocáveis (MgCl2) nessas mesmas camadas variaram de 231 a 1.407 mg kg-1, para Zn; 14 a 390 mg kg-1, para Cd, e 11 a 33 mg kg-1, para Pb; o Cu raramente ocorreu nesta forma. Os solos dos locais estudados, com teores excessivos de Zn, Cd, Cu e Pb, são considerados poluídos. Em determinados locais contaminados por escoamento (superficial e subsuperficial) e arraste de material de solo e rejeito, a poluição mostrou-se mais evidente nas camadas superficiais. No local da ustulação, verificou-se maior percentagem de Zn trocável em todos os níveis de profundidade. Nos demais locais, o Cd apresentou também grandes concentrações nas formas trocáveis, razão por que tal elemento oferece maior risco de contaminação ambiental. De modo geral, a ocorrência de Zn foi maior nas formas carbonato e residual, enquanto o Cd predominou nas formas trocáveis e o Cu e Pb nas formas residuais. A extração dos metais por Mehlich-1 e DTPA correlacionou-se significativamente com a soma das extrações com MgCl2 e NaOAc do fracionamento, para praticamente todos os elementos analisados. Por essa razão, recomendam-se futuros estudos com aqueles extratores em termos de mensuração de metais potencialmente disponíveis ao ambiente.

Simultaneous All-Optical Waveform Reshaping of Two 10-Gb/s Signals Using a Single Injection-Locked Fabry–PÉrot Laser Diode (2004)

All-optical waveform reshaping of a distorted 10-Gb/s nonreturn-to-zero (NRZ) pseudorandom bit sequence (PRBS) signal using two-mode injection locking in Fabry-Perot laser diode (FP-LD) was demonstrated. Simultaneous waveform reshaping of two 10-Gb/s distorted NRZ PRBS signals using a single FP-LD was also demonstrated.
Large Scale Synthesis of Manganese Oxide/Reduced Graphene Oxide Composites as Anode Materials for Long Cycle Lithium Ion Batteries (2021)

Manganese oxides have been frequently used as cathodes in primary batteries. Applications of manganese oxides in secondary batteries are limited by low electrical conductivity and rapid capacity fading because of electrode pulverization and aggregation. In this study, a solid-state synthetic strategy is presented that successfully combines nanosize (∼50 nm) nickel doped α-MnO2 with reduced graphene oxides as highly stable composite anodes in lithium ion batteries. The synthesis approach is easy to scale up and suitable for industrial applications. The rationally designed Ni-α-MnO2/RGO was tested in galvanostatic half coin cells for Li+ charge–discharge studies. The results show that this composite maintains a high capacity of 615 mAh g–1 even after 200 cycles at a high current rate of 1 C (830 mA g–1), and with a high Coulombic efficiency near 99%. The anodes exhibit excellent rate capability in a wide range of rate testing from 0.2 to 10 C, without showing capacity decay. This superior anode performance is ascribed to the reduced size of α-MnO2 domains that are well dispersed in an RGO matrix, which affords good ionic/electrical conductivity, low charge transfer resistance and mitigates issues of volume expansion of the anodic active materials. This study opens up an avenue for developing the manufacturing of high-performance electrodes for real applications, such as batteries in electrical vehicles.
Copper(I) Alkoxides and Aryloxides (1997)

Copper(I) alkoxides and aryloxides have been prepared from mesitylcopper(I) and alcohols or phenols. The solid state structures of the alkoxides and aryloxides are .my.2- and/or .my.3-OR bridged Cun clusters (R: (C6H5)2C, CH2=CHCH2C6H4, (C6H5)2C6H3, n = 4; (CH3)3C, n = 8; H2C=CH(CH3)2C, n = 6), containing two-, three- or four-coordinated copper(I) centres, with Cu-O bond distances ranging from 1.834(7) to 2.785(6) Å. The reaction between mesitylcopper(I) and alcohols or phenols in a carbon monoxide atmosphere resulted in carbonyl complexes of copper(I) alkoxides or copper(I) aryloxides, in which a single CO binds to copper. A decrease of the aggregation number, and, in general, an appreciable lengthening of the Cu-O bond distance is observed. The terminally bonded CO is labile and the Cu-C bond is judged to be predominantly of s character, with minimal metal - ligand .pi.* contribution. Nevertheless, carbon monoxide can be used to isolate derivatives of copper(I) aryloxides which otherwise defy isolation. Methylbutenoxocopper(I) [Cu6(OC(CH3)2C(H)=CH2)6 ] and o-allylphenoxocopper(I) [Cu4(OC6H4CH2C(H)=CH2 )4], contain copper(I) centres .pi.-coordinated by the intramolecular allylic group. In solution the copper(I)-alkene bond in methylbutenoxocopper(I) is broken, while it remains intact in o-allylphenoxocopper(I). Contrary to methylbutenoxocopper(I), o-allylphenoxocopper(I) does not react with carbon monoxide and is unusually stable at ambient atmosphere, both in the solid state and in contact with non-coordinating solvent. Reaction of triphenylphosphine and copper(I) phenoxide in a molar ratio of PPh3:Cu of 1:1 resulted in a tetrameric m3-phenoxide complex, with a cubane-type Cu4O4 core and four-coordinated copper(I). Changing the PPh3:Cu ratio to 1.5:1 gave a dimeric .my.2-phenoxide complex in which one copper(I) centre is four-coordinated by two phenoxide and two PPh3 ligands, while the other is coordinated by a single PPh3 ligand and thus three-coordinated.
Dosimetric Evaluation of the Mean Glandular Dose for Mammography in Korean Women: A Preliminary Report (2003)

The purpose of this study was to evaluate the thickness of the compressed breast in mediolateral oblique (MLO) and craniocaudal (CC) mammograms, to relate these thickness and breast patterns to mean glandular dose (MGD) in Korean women, and to evaluate the suitability of using the American College of Radiology's Recommendations for Korean women from a quality assurance standpoint. The study population consisted of 92 paired MLO and CC mammograms obtained on one mammographic unit. The digital readouts of compressed breast thickness, applied compression force and tube voltage were recorded. Entrance skin exposure was measured by dosimetry. MGD was calculated by multiplying entrance skin exposure by the exposure-to-absorbed dose conversion factor. The range of breast thickness was 1.3-6.2 cm in CC mammograms with a mean breast thickness of 3.6 cm, and 1.6-6.5 cm in MLO mammograms with a mean breast thickness of 3.9 cm. MGDs in CC and MLO mammograms were 1.77 mSv and 1.88 mSv per view, respectively. Breast composition patterns were divided into 4 groups according to ACR BI-RADS; P1 (n=20), P2 (n=16), P3 (n=48) and P4 (n=8). The MGDs for these groups were: 1.82, 1.84, 1.84, and 1.91 mSv, respectively. When subjects were subdivided by breast thickness into three groups, namely, below 3 cm, 3 cm to 4.2 cm, aaa and above 4.2 cm, the corresponding MGDs were 1.83, 1.86, and 1.91 mSv. According to our initial trial, the mean breast thickness and the MGDs of Korean women are lower than recommended by the American College of Radiology, which are commonly used for quality assurance purposes.
Musical Venues in Vienna, Seventeenth Century to the Present (1995)

RILM abstract: "Consideration of musical venues is often neglected in research on historical performance practice. Many musical works are directly linked to a particular location. The characteristic features (type, size, Acoustics) of the room or building for which the music was written influenced the composer in the creation of his work. A number of venues have had a special place in the musical life of Vienna over the past four centuries. A list of principal Viennese musical buildings (theaters, opera houses, music rooms, concert halls) is included, along with the circumstances surrounding their construction, and the more important musical works--especially premieres--presented in them."
Environment-Friendly Assessment of Passive Apartment House Based on Major Building Materials in Korea (2014)

The purpose of this study is to assess environmental friendliness of passive apartment house based on major building materials in Korea. To accomplish this, stage-wise quantity information of life cycle and energy consumption data were established on major materials through theoretical consideration on life cycle assessment. In addition, basic unit database from Korean LCI DB was utilized to assess and analyze characterization value of global warming assessment. As a result, the value of global warming was smaller in passive apartment house in comparison to general apartment house. As the effect of building materials in construction stage was analyzed to be greater than the effect of energy consumption in operation stage, development of diverse building materials taking environmental impact into account is deemed necessary.
Other one-dimensional systems and thermal properties (2008)

Since the ICON 2007 conference was heavily focused on nanowires, one session was devoted to providing a broader picture of one-dimensional systems and how thermal properties are enhanced in these low-dimensional systems. This article is directed toward giving an overview of these topics, summarizing some of the most relevant issues, and providing a vision for the future directions of these topics.
LEACH-WM: Weighted and intra-cluster multi-hop energy-efficient algorithm for wireless sensor networks (2016)

In order to minimize energy dissipation and maximize network lifetime, a new energy-efficient algorithm (LEACH-WM) based on weight and intra-cluster multi-hop mechanism is proposed in this paper. In the steady phase of LEACH-WM, a weight relay is elected in the cluster according to member nodes' residual energy and their distances away from the base station (BS).Cluster head sends aggregation data to its weight relay, which then forwards data to the BS. This process minimizes energy dissipation of the cluster head. The above mechanism distributes energy dissipation more uniformly in the network and further prolongs network life time. Simulations show that LEACH-WM does make alive nodes and dead nodes distribute more evenly in the network and it outperforms LEACH, LEACH-DCHS (Low Energy Adaptive Clustering Hierarchy with Deterministic Cluster-Head Selection) and TB-LEACH (A Time-based Cluster-Head Selection Algorithm for LEACH)in terms of network lifetime and energy dissipation.
Effect of Heat Treatment and Elongation on Localized Heat Generation in Low-Density Polyethylene Film (1996)

The authors already reported that localized heat generation appears before dc breakdown of low-density polyethylene film, which shows the contribution of thermal process to the breakdown. This paper describes the further study on the localized heat generation leading to dielectric breakdown in a low-density polyethylene film and the effect of heat treatment and elongation on it. To study the effect of density of polyethylene, very-low-density polyethylene (VLDPE) and high-density polyethylene (HDPE) films were also used. It was observed that the localized heat generation was suppressed after the heat treatment but was promoted after the elongation of the film. In VLDPE film, localized heat generation and dielectric breakdown occurred at obviously lower electric field than those in LDPE film. On the other hand, the localized heating was scarcely detected in HDPE film. These results indicate that the weak point where localized heat generation and breakdown occur might be one where local density or crystallinity is lower.
Spinal descent of cerebrospinal fluid in man (1976)

The descent of radiopharmaceuticals injected within the right lateral ventricle toward and into the spinal subarachnoidal spaces has been followed by scintiphotographic techniques and by computerized flow analysis in a group of "normal" patients. A substantial and rapid downward progression of the albumin-tagged tracer has been observed. This progression is faster than the subarachnoidal ascent toward the convexity of the brain.
Studies on process and nutritional parameters for production of alkaline protease by Thermoactinomyces thalpophilus PEE 14 (2005)

Studies on process and nutritional parameters for the production of extracellular alkaline protease employing Thermoactinomyces thalpophilus PEE 14 was carried out. Different initial pH, incubation temperatures and time and inoculum levels and their age were studied. Effects of different nutritional parameters, trace elements and metabolic inhibitors on protease production were also studied. The maximum enzyme activity was obtained with incubation temperature of 55oC, initial pH of 10, incubation time of 24 h, level of inoculum 10 per cent and age of the inoculum 72 h. Results of nutritional and trace element parameters showed that pyridoxin, L-cysteine and sodium molybdate showed best vitamin, amino acid and trace elements, respectively. Silver nitrate, antibiotic framycitine and surfactant cetrimide showed strong inhibitory effect on protease production.
One time programmable drift antifuse cell reliability (2002)

An innovative non-volatile memory cell based on gate oxide breakdown is presented. The full compatibility with a standard CMOS process and the limited programming current per cell make the drift antifuse a low cost and dense non-volatile storage solution. Reliable storage is demonstrated and results from both device architecture and design optimization are given.
Mounting evidence for an ehrlichial involvement in systemic lupus erythematosus (2012)

H agents, well studied in veterinary medicine, were first suggested as a human pathogen in an article in Nature New Biology in 1972, and there is growing evidence of their involvement in systemic lupus erythematosus (SLE). Over the last four decades a small body of published and unpublished research has reported the following: Ehrlichial antigens identified in the glomeruli of patients with lupus nephritis; Ehrlichia-like intra-erythrocytic inclusions in patients with SLE and endosomal structures suggestive of Ehrlichia in the marrow of patients with SLE. Furthermore, compassionate antibiotic treatment of very ill patients using an antibiotic known to be effective against Ehrlichial agents was conducted, with strongly positive results including changes in observed intra erythrocytic bacterial structures. Self-reactive antibodies are characteristic of SLE and Ehrlichia have been shown to produce errors in transcription in parasitized cell division especially in proliferating cells of the marrow. If Ehrlichia invade the immune system through activity against bone marrow cells (especially stem cells or other precursors of mature B and/or T cells) and interfere with their construction, function and elimination before release to the circulation, the body may be unable to eliminate them in a normal fashion and the self-reactive antibodies would be unleashed on the tissues of the infected patient. Molecular studies using the genetic sequences of the Ehrlichia identified in a human patient with another possibly related illness of the immune system should be undertaken to see if it can be positively identified in the marrow and blood of lupus patients. If so, a compelling alternative explanation of the disease complex of SLE would be proved.

Isolation of Human Brain Endothelial Cells and Characterization of Lipid Raft-Associated Proteins by Mass Spectroscopy (2010)

The blood-brain barrier (BBB) limits the movements of molecules, nutrients, and cells from the systemic blood circulation into the central nervous system (CNS), and vice versa, thus allowing an optimal microenvironment for CNS development and function. The brain endothelial cells (BECs) form the primary barrier between the blood and the CNS. In addition, pericytes, neurons, and astrocytes that make up the neurovascular unit support the BEC functions and are essential to maintain this restrictive permeability phenotype. To better understand the molecular mechanisms underlying BBB properties, we propose a method to study the proteome of detergent resistant microdomain, namely lipid rafts, from human primary cultures of BECs. This chapter describes a robust human BECs isolation protocol, standard tissue culture protocols, ECs purity assessment protocols, lipid raft microdomain isolation method, and a mass spectrometry analysis technique to characterize the protein content of membrane microdomains.
Optimization on Delay and Slot Utilization for Fieldbus Control System Based on UWB (2007)

The UWB (ultra wide band) technology is ideally suited for the development of FCS (fieldbus control system) in industrial environments because of desirable features such as high data rates, low power consumption, precise ranging capabilities, resistance to multi-path fading, and penetration of dense objects. But, owing to a lot of short packets in the FCS applications and high channel acquisition time in UWB, the delay is larger than in other application. This paper studies delay and slot utilization about FCS based on UWB. The slot utilization is defined as the fraction of time that useful data is transmitted per slot. We add a packet optimization layer (POL) in the model of FCS based on UWB and introduce to aggregate multiple upper-layer packets idea in the POL. Finally, we evaluate the performance of the proposed special packet assembly mechanism for FCS based on UWB. Simulation results show that it is effective to improve on performance of the delay and slot utilization in the FCS based on UWB.
The magnetic properties of platinum cobalt near the equiatomic composition part II. mechanism of magnetic hardening (1966)

Abstract The dispersion and crystallography of the ordered tetragonal phase are discussed and a detailed model of the magnetic hardening process in PtCo presented. It is shown that small ordered particles of high anisotropy can pin domain walk and give rise to the observed hardening. The temperature variation of coercivity is explained in terms of a thermal fluctuation model and estimates of particle size from field ion microscopy, x-ray line broadening, and magnetic measurements are compared.

Resource Central (2017)

Cloud research to date has lacked data on the characteristics of the production virtual machine (VM) workloads of large cloud providers. A thorough understanding of these characteristics can inform the providers' resource management systems, e.g. VM scheduler, power manager, server health manager. In this paper, we first introduce an extensive characterization of Microsoft Azure's VM workload, including distributions of the VMs' lifetime, deployment size, and resource consumption. We then show that certain VM behaviors are fairly consistent over multiple lifetimes, i.e. history is an accurate predictor of future behavior. Based on this observation, we next introduce Resource Central (RC), a system that collects VM telemetry, learns these behaviors offline, and provides predictions online to various resource managers via a general client-side library. As an example of RC's online use, we modify Azure's VM scheduler to leverage predictions in oversubscribing servers (with oversubscribable VM types), while retaining high VM performance. Using real VM traces, we then show that the prediction-informed schedules increase utilization and prevent physical resource exhaustion. We conclude that providers can exploit their workloads' characteristics and machine learning to improve resource management substantially.
Cytoplasmic myosin from Drosophila melanogaster. (1986)

Myosin is identified and purified from three different established Drosophila melanogaster cell lines (Schneider's lines 2 and 3 and Kc). Purification entails lysis in a low salt, sucrose buffer that contains ATP, chromatography on DEAE-cellulose, precipitation with actin in the absence of ATP, gel filtration in a discontinuous KI-KCl buffer system, and hydroxylapatite chromatography. Yield of pure cytoplasmic myosin is 5-10%. This protein is identified as myosin by its cross-reactivity with two monoclonal antibodies against human platelet myosin, the molecular weight of its heavy chain, its two light chains, its behavior on gel filtration, its ATP-dependent affinity for actin, its characteristic ATPase activity, its molecular morphology as demonstrated by platinum shadowing, and its ability to form bipolar filaments. The molecular weight of the cytoplasmic myosin's light chains and peptide mapping and immunochemical analysis of its heavy chains demonstrate that this myosin, purified from Drosophila cell lines, is distinct from Drosophila muscle myosin. Two-dimensional thin layer maps of complete proteolytic digests of iodinated muscle and cytoplasmic myosin heavy chains demonstrate that, while the two myosins have some tryptic and alpha-chymotryptic peptides in common, most peptides migrate with unique mobility. One-dimensional peptide maps of SDS PAGE purified myosin heavy chain confirm these structural data. Polyclonal antiserum raised and reacted against Drosophila myosin isolated from cell lines cross-reacts only weakly with Drosophila muscle myosin isolated from the thoraces of adult Drosophila. Polyclonal antiserum raised against Drosophila muscle myosin behaves in a reciprocal fashion. Taken together our data suggest that the myosin purified from Drosophila cell lines is a bona fide cytoplasmic myosin and is very likely the product of a different myosin gene than the muscle myosin heavy chain gene that has been previously identified and characterized.
