AVALIAÇÃO TÉCNICO-ECONÔMICA DA SUBSTITUIÇÃO DO MILHO PELA QUIRERA DE ARROZ EM DIETAS DE SUÍNOS/ TECHNICAL-ECONOMICAL EVALUATION OF SUBSTITUTING CORN FOR BROKEN RICE IN SWINE FEED

O objetivo deste trabalho foi avaliar o desempenho e as caracteristicas quantitativas da carcaca de suinos, nas fases de crescimento e terminacao, quando alimentados com dietas contendo quirera de arroz (QA) em substituicao ao milho. Foram utilizados 72 suinos machos castrados, distribuidos em delineamento de blocos ao acaso, composto por 3 tratamentos (dietas contendo 0, 50 e 100% de QA em substituicao ao milho) com seis repeticoes, sendo cada unidade experimental constituida por quatro animais. O consumo de racao diario medio, o ganho de peso diario medio e o peso final dos animais nao foram influenciados pelos tratamentos (p>0,05). Animais alimentados com dieta contendo 100% de QA em substituicao ao milho apresentaram melhor conversao alimentar (p 0,05). Animais alimentados com dieta contendo 100% de QA apresentaram maior profundidade de musculo em relacao aos alimentados com a dieta contendo 50% de QA (p 0,05). Concluiu-se que a QA pode substituir totalmente o milho nas dietas de suinos nas fases de crescimento e terminacao, sem prejudicar as caracteristicas quantitativas da carcaca.
Molecular Dynamics Study on the Effects of Chain Branching on the Physical Properties of Lipid Bilayers: 2. Permeability

We studied the effects of chain branching on the water and nonionic (neutral) solute permeability of lipid bilayers in a molecular dynamics simulation comparing two bilayers: dipalmitoylphosphatidylcholine (DPPC) and diphytanoylphosphatidylcholine (DPhPC). The calculated free energy profiles of several neutral solute and water molecules across the lipid membranes showed that chain branching caused no significant changes in the solubility of these molecules inside the membrane core. However, an analysis of the cavity distribution in each of these bilayer systems demonstrated that the branch-chained DPhPC bilayer had, compared with the straight-chained DPPC bilayer, a relatively small and discrete free volume distribution in the hydrophobic part. This suggests that small penetrants have a lower rate of diffusion inside branch-chained lipid bilayers. Actually, water molecules showed lower local diffusion coefficients inside the DPhPC membrane than inside the DPPC membrane. The low penetrant mobility of the .
Ozone formation in relation with combustion processes in highly populated urban areas

The complex chain of photochemical reactions is one of the most important tasks in the air quality evaluation, expecially in urban areas. In fact, in this case there are high emission levels of NOx and no-methane hydrocarbons by combustion processes such as autovehicular traffic, domestic heating and industrial plants. Ozone is not emitted directly into the atmosphere but it is formed from a complex series of reactions between emitted nitrogen oxides (NOx) and reactive organic compounds (ROC). The high ozone concentrations, which occur during photochemical episodes, are usually accompanied by elevated concentrations of other photochemical oxidants such as nitric acid (HNO3), peroxyacylnitrates (PANs), hydrogen peroxide (H2O2), etc. The complex series of these reactions constitutes the most important issue to the degradation of air quality. Further, the NMHCs play a key role in the formation of photochemical air pollution: they are considered as precursors for ozone production at the ground level when the sunlight and nitrogen oxides are present. From a practically point of view defining a quality standard or a limit is substantially correct but it is no sufficient to solve the problem. So it should become necessary to acquire knowledge on the different formation mechanisms of the photochemical pollution phenomena. In this paper there will be shown the results of a long-term study performed in Rome for evaluating the ozone formation in relationship with the autovehicular traffic density.
Treatment of low-turbidity water by sweep coagulation using clay

A novel strategy of sweep coagulation to treat low-turbidity water is presented herein. Preliminary study findings demonstrate the feasibility of employing flocs formed by coagulation of montmorillonite suspension with cationic polyelectrolyte as a surrogate to the amorphous Al(OH)3 precipitated in sweep coagulation. Excellent efficiency of turbidity removal is attained via physical entrapment of TiO2 particles within the flocculating montmorillonite flocs.
Compost Treatments Interact with Other Factors To Affect Red Radish Production

Spent mushroom substrate and yard waste compost each were applied to the soil surface at two depths (equivalent to 2.5 or 5 cm) and then incorporated in order to study effects on spring and fall production of red radishes (Raphanus sativus L.). Other variables examined were radish cultivars and, in one fall experiment, the presence or absence of the herbicide trifluralin. Spent mushroom substrate gave seasonally-variable results, including a distinct negative effect on yield when applied at 204 Mg.ha−1 (a layer 5 cm deep) for fall production. Yard waste compost improved yield as compared to unamended soil when trifluralin was used; however, no benefit was demonstrated in the absence of the herbicide. Hybrid cultivars produced higher yields overall than open-pollinated cultivars, but there was some overlap between specific cultivars, and compost x cultivar interactions were evident in two of three experiments. Spent mushroom substrate is not recommended as a soil amendment for radish production when stand establishment occurs under hot, dry conditions. Further research is needed to determine the potential usefulness of yard waste compost as a soil amendment for field production of radish in the absence of a phytotoxic herbicide. Chemical name used: 2,6-dinitro-N,N-dipropyl-4-(trifluoromethyl)benzenamine (trifluralin).
Exosome-Based Delivery of Natural Products in Cancer Therapy

A rapidly growing research evidence has begun to shed light on the potential application of exosome, which modulates intercellular communications.

The recent progress and challenges of using exosomes as drug delivery vehicles for five representative anti-cancer natural products including paclitaxel, curcumin, doxorubicin, celastrol, and β-Elemene. Based on the discussion on the current knowledge about exosomes as delivery vehicles for drugs and natural compounds to the targeted site, this review delineates the landscape of the recent research, challenges, trends and prospects in exosomes as delivery vehicles for drugs and natural compounds for cancer treatment.
Approximating the Impact of Sorption on Biodegradation Kinetics in Soil-Water Systems

Naphthalene sorption and biodegradation were quantified in three soils of varying organic C content using miscible displacement and batch incubation techniques. As anticipated, sorption increased with organic C content; the sorption rate coefficient and equilibrium sorption constant (K d ) were inversely related. Organic matter in solution (NOM) from the high-organic-matter soil decreased apparent sorption, which was also quantified using methanol as a cosolvent. A cosolvency power of 3.8 or 4.1 was determined. The initial biodegradation rate decreased with increasing sorption and was a function of naphthalene concentration in solution. The extent of biodegradation was greatest in the high-organic-matter soil and decreased when NOM was removed from the system. The observed dependence of biodegradation kinetics on sorption (this study and in the literature) prompted us to develop a simple approach for approximating a biodegradation rate constant for soil-water systems. This approach combines independently determined sorption parameters with the biodegradation rate constant determined for aqueous (soil-free) solution. The approach was applied to our data and to published data where sorption was shown to control naphthalene biodegradation. The approximated biodegradation rate constant was within 10% of the measured values for three cases, 20% for a fourth case, and was underestimated by five-to sevenfold for the high-organic-matter soil. The approach will be useful when applying management models for predicting contaminant fate and transport that require a degradation rate constant, or for estimating biodegradation rates in situations where cultured organisms are introduced for biodegradation.
SpMV Runtime Improvements with Program Optimization Techniques on Different Abstraction Levels

The multiplication of a sparse matrix with a dense vector is a performance critical computational kernel in many applications, especially in natural and engineering sciences. To speed up this operation, many optimization techniques have been developed in the past, mainly focusing on the data layout for the sparse matrix. Strongly related to the data layout is the program code for the multiplication. But even for a fixed data layout with an accommodated kernel, there are several alternatives for program optimizations. This paper discusses a spectrum of program optimization techniques on different abstraction layers for six different sparse matrix data format and kernels. At the one end of the spectrum, compiler options can be used that hide from the programmer all optimizations done by the compiler internally. On the other end of the spectrum, a multiplication kernel can be programmed that use highly sophisticated intrinsics on an assembler level that ask for a programmer with a deep understanding of processor architectures. These special instructions can be used to efficiently utilize hardware features in processors like vector units that have the potential to speed up sparse matrix computations. The paper compares the programming effort and required knowledge level for certain program optimizations in relation to the gained runtime improvements.
The Relation of FTIR Signature of Natural Colorless Quartz to Color Development After Irradiation and Heating

Amethyst, prasiolite, citrine, and morion are gemstones widely used to make jewelry, to compose mineral collections of museums or private persons, or to decorate homes and offices. They are all alpha quartz (Dana et al., 1985) and the differences between them are very small. The natural quartz always has trace elements in its crystal structure, such as aluminum, iron, hydrogen, lithium, sodium, and potassium. The content of these trace elements is important for color development. But without exposure to ionizing radiation, these trace elements are not able to produce colors in quartz.
Oxide Materials for Development of Integrated Gas Sensors—A Comprehensive Review

ABSTRACT In the recent past a great deal of research efforts were directed toward the development of miniaturized gas-sensing devices, particularly for toxic gas detection and for pollution monitoring. Though various techniques are available for gas detection, solid state metal oxides offer a wide spectrum of materials and their sensitivities for different gaseous species, making it a better choice over other options. In this article a critical parameter analysis of different metal oxides that are known to be sensitive to various gaseous species are thoroughly examined. This includes phase of the oxide, sensing gaseous species, operating temperature range, and physical form of the material for the development of integrated gas sensors. The oxides that are covered in this study include oxides of aluminum, bismuth, cadmium, cerium, chromium, cobalt, copper, gallium, indium, iron, manganese, molybdenum, nickel, niobium, ruthenium, tantalum, tin, titanium, tungsten, vanadium, zinc, zirconium, and the mixed or multi-component metal oxides. They cover gases such as CO, CO2, CH4, C2H5OH, C3H8, H2, H2S, NH3, NO, NO2, O2, O3, SO2, acetone, dimethylamine (DMA), humidity, liquid petroleum gas (LPG), petrol, trimethylamine (TMA), smoke, and many others. Both doped and undoped oxides are analyzed for the compatibility with silicon processing conditions and hybrid microcircuit fabrication techniques. In silicon processing conditions, they are further analyzed for the suitability for simple silicon surfaces, silicon-on-insulator (SOI) surfaces, and micromachined silicon geometries for different operating temperatures. Discussion on gas-sensing properties of each material and its applications are described in the text in alphabetical order of the elemental oxides. Further, the gas-sensing properties like sensitivity, detection limits, operating temperature, and so on are summarized in tables al ong with relevant references. The figures incorporated in the present review are primarily based on discussions and data in tables. However, these figures provide a qualitative comparison and present a pictorial view to examine suitability of a material for a particular application. From the known parameters, the present study clearly indicates the suitability of certain materials and the gases that they cover for the development of integrated micro gas sensors. A clear picture has been brought out for the development of silicon-based processing technology. Various parameters are discussed for the selection of these materials, to examine their suitability and practical problems that are being associated. Etching of these metal oxides and the reliability of devices are also discussed.
Development of cross-linked chitosan films for oral mucosal delivery of lidocaine

Lidocaine (LC) is a local anesthetic agent. The aim of this study was to prolong the anesthetic effect of this drug in the oral cavity in the treatment of oral mucositis. Films of LC were prepared with three different molecular weights (MW) of chitosan in three different concentrations (1-3%) and were then cross-linked by solvent casting evaporation method with tripolyphosphate penta sodium salt (TPP) in two concentrations (0.1 and 0.3%). Cross-linking time was 5 min and the solvent was evaporated by oven at 37 oC. Bioadhesion, tensile strength (TS), the release and flux of drug through the films were studied. Increasing the concentration of chitosan caused decreasing the bioadhesion while increasing its MW did not change the bioadhesion significantly. The bioadhesion of cross-linked films was comparable to similar films. Cross-linking the films with TPP and increasing the chitosan MW significantly increased their TS compared to films obtained from the gels. Drug release profiles showed that increasing the concentration and MW of chitosan caused an increase in both the rate and extent of drug release. Lidocaine flux was increased by MW and concentration of chitosan but increasing TPP concentration significantly decreased it. Films prepared by 3% of high MW of chitosan and cross-linked by 0.1% of TPP (H3T1) showed a higher flux of drug (212.59 ± 26.31 mg/cm2/hr), and relative high bioadhesion and TS. This film is expected to prolong release of LC in buccal area and is suggested for further clinical studies to evaluate its produced onset and duration of anesthesia.

Single-molecule spectroscopy at subkelvin temperatures

The work presented in this thesis has involved the measurement of fluorescenceexcitation spectra of single-molecules doped in crystalline and disordered host matrices down to a temperature of 30 mK. By measuring the linewidths as a function of temperature, one obtains information about the broadening mechanisms at hand. In addition, at very low temperature one can direct1y measure the lifetime-limited linewidth, which until now has usually been assumed to be equal for all molecules. In this thesis, it is shown that this is not the case, and that the width of the lifetimelimited linewidth distribution depends on the level of disorder in the host. The first half of this thesis provides background for understanding the second half, in which the experimental results are presented. The background is presented in four chapters covering the areas of the fundamentals of single-molecule spectroscopy, transition dipole moments and the local field factor, the tunneling two-level system model, and single-molecule lineshape theory. The presentation of the measurements begins with a single-molecule microscopy study of the linewidth distributions for single terrylene and ditertbutylterrylene molecules in polyvinylbutyral at 1.8 K, which motivated the measurements that were performed at lower temperature. It is shown that the results are in disagreement with the standard tunneling two-level system model, but that the incorporation of a distribution of molecule-polymer coupling strengths removes this disagreement. Additionally, the experimental observation of a correlation between the single-molecule line areas and the matrix-rnolecule interaction strength is presented. Both the necessity for a distribution of coupling strengths and the existence of the correlation
Interplay of solvent motion and vibrational excitation in electron-transfer kinetics : experiment and theory

This paper reports new kinetic data on the electron-transfer kinetics of betaine-30 and the related compound tert-butylbetaine. The experimental data are in excellent agreement with a new theoretical model which is an extension of the approach given by Sumi and Marcus (Sumi, H; Marcus, R. A. J. Chem. Phys. 1986, 84, 4894). Most of the parameters required for the kinetic predictions can be obtained in a straightforward fashion by fitting the static absorption spectra of the charge-transfer band
