    The objectives are set to establish the techniques for observation/manipulation of atoms and molecules, as the common basic techniques for various industrial areas, e.g., new materials, electronics, biotechnology and chemical. Development of atomic field and scanning tunneling microscopes working under extreme conditions has been pursued, in order to manipulate complex systems, such as living body. For identification of molecular species, laser-excited fluorescence is combined with scanning mechanical probing to further refine the single molecule detection/identification techniques, and the objectives are set to develop a new method for evaluating molecules in a living body using a scanning probe microscope, and also to develop a novel scanning probe microscope for molecules in a living body. The other efforts were directed to R and D of the techniques for observing structures of organic molecules and the like through the measurements of adsorption process of organic molecules and clusters on semiconductor substrates and their surface reactions, and precision measurements of vibrational conditions of adsorbed molecular species reacting in the solid-liquid interfaces by high-sensitivity Raman spectroscopy to elucidate the catalysis mechanisms at the molecular level.

    This paper describes R and D of the ultimate manipulation technology of atoms and molecules (atom technology). Through the observation of super spiral DNA fixed on a spermin or spermidine treated mica substrate by AFM (atomic force microscope), fixation of DNA without any deformation in solution was clarified, and visualization of the spiral structure of DNA were successfully achieved. Manipulation of Xe atoms adsorbed on an Si(111) surface was certainly possible by using STM (scanning tunneling microscope)/atom probe equipment. A nucleation mechanism in crystal growth was studied for various organic source-molecules/GaAs(001) surface systems, and formation of high-density nuclei on the GaAs surface was achieved by accelerating the translational energy of Ga material molecules up to 6eV or more. Ziegler- Natta catalysis important for industrial polymerization of olefin molecules was precisely analyzed by first-principle dynamic simulation. A large-scale simulation of zeolite catalyst is also in promotion for methanol to gasoline conversion. 51 refs., 87 figs., 7 tabs.

    This paper describes R and D of the ultimate manipulation technology of atoms and molecules (atom technology). Ten nanoscale Ge islands were successfully formed in proper positions on an Si substrate surface by using mask technology of nanoscale atomic layers. Growth of less-defect ZnSe films on a GaAs(110) surface was possible under various conditions. The magnetic transfer mechanism of Mn oxide with huge reluctance was clarified. Through study on selective-area deposition of Si on plasma-oxidized ultrathin SiO2 mask layers patterned by direct electron-beam exposure and an idea of SiO2/SiNx bilayer mask, direct use of the ultrathin mask layer as insulating layer in device structure was achieved. The superior property as electron beam resist of methano- fullerene composed of fullerene C60 with side chains including oxygen was clarified. The initial oxidation process of an Si(100) surface was analyzed, and the observation result by SREM was theoretically explained. Development of a high-resolution spin polarization electron microscope was also mentioned. 48 refs., 145 figs., 20 tabs.

    The Sensor Open System Architecture (SOSA) is a C4ISR-focused technical and economic collaborative effort between the Air Force, Navy, Army, the Department of Defense (DoD), Industry, and other Governmental agencies to develop (and incorporate) a technical Open Systems Architecture standard in order to maximize C4ISR sub-system, system, and platform affordability, re-configurability, and hardware/software/firmware re-use. The SOSA effort will effectively create an operational and technical framework for the integration of disparate payloads into C4ISR systems; with a focus on the development of a modular decomposition (defining functions and behaviors) and associated key interfaces (physical and logical) for common multi-purpose architecture for radar, EO/IR, SIGINT, EW, and Communications. SOSA addresses hardware, software, and mechanical/electrical interfaces. The modular decomposition will produce a set of re-useable components, interfaces, and sub-systems that engender reusable capabilities. This, in effect, creates a realistic and affordable ecosystem enabling mission effectiveness through systematic re-use of all available re-composed hardware, software, and electrical/mechanical base components and interfaces. To this end, SOSA will leverage existing standards as much as possible and evolve the SOSA architecture through modification, reuse, and enhancements to achieve C4ISR goals. This paper will present accomplishments over the first year of SOSA initiative.

  6. Sentiment Contagion Based on the Modified SOSa-SPSa Model

    Full Text Available Sentiment contagion is similar to an infectious disease that spreads in a crowd. In this study, we extend the proposed SOSa-SPSa model (susceptible-optimistic-susceptible and susceptible-pessimistic-susceptible by considering the interaction between optimists and pessimists. Simulation results show that our model is reasonable and can better explain the entire contagion process by considering three groups of people. The recovery speed of pessimists has an obvious regulative effect on the number of pessimists and the possibility of optimists coming in contact with pessimists to be infected as pessimism plays a greater role than that of reverting to susceptibility. The number of pessimists is positively related to the possibility that optimists come in contact with pessimists to become pessimistic but is negatively related to the possibility of the other way around. When the speed of spontaneous generation is slow, the number of pessimists sharply increases. However, the increase is not so apparent when the speed of spontaneous generation reaches a certain number.

    Full Text Available From the Middle Ages onwards plant ashes were commonly used throughrout Europe in the elaboration of soap and glass. These ashes were known by different names depending on the vegetables employed and the quality of the product. In Spain sosa (soda and barrilla (barilla were the most widespread.
    Due to the reconceptualization of their primary references, these two words underwent considerable semantic changes during the XVIIIth and the XIXth centuries. The aim of this paper is to survey these changes focusing on their intralinguistic factors.

Debido a la reconceptualización de sus referencias iniciales, ambas denominaciones sufrieron considerables cambios semánticos durante los siglos XVIII y XIX. El propósito de este artículo es observar estos cambios subrayando los factores intralingüísticos.

    Harmonized molecular materials (HMM) were researched to create functional materials adaptable to needs such as environmental harmony and high-efficient conversion in post-industrial society and aging society. Superior mechanisms function efficiently in organisms for perception, transmission and processing of information, and transport and conversion of substances. These functions are caused by harmonization between organic molecules, or organic molecule and metal or inorganic substance. HMM is a key substance to realize these functions similar to those of organisms artificially. It is the purpose of this research to develop HMMs, reform production process by innovating separation and conversion technologies, and finally realize molecular chemical plants. This research also develops high-efficient devices to contribute to the information society, and progresses the industry of bio-functional materials such as high-sensitive bio-sensor. The functions, applications and creation technologies of three kinds of HMM such as assembly, mesophase and microporous materials were researched in fiscal 1995. 956 refs., 128 figs., 13 tabs.

    This paper describes a quantum chemistry approach to organism molecules being made possible from advancing electronic computers. The results of studies at the Molecular Chemistry Research Institute are presented, that have pursued out-of-plane movements of iron ions in hemoglobin's oxygen adsorption and desorption using the molecule orbital theory. Iron ions of dioxiheme not attached with oxygen molecules belong to a group with the smallest curvature and are in a state easily drawn out of the plane. When attached with oxygen, the iron ions change to a group with the largest curvature, becoming difficult to exit out of the plane. These facts revealed that the molecule called heme plays a role of translational motor in a micromachine, from which designing a micromachine in nanometer orders can be expected. The Kyushu Institute of Technology has introduced a network system for education and research of life science, and completed arranging an environment that enables executing numerical simulation of living organism systems, and homology analyses of protein and nucleic acid. 5 refs., 8 figs.

    HMX, nitramine-based high performance explosive, is a ring nitramine compound called chemically octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine, and has 4 kinds of crystal polymorphs, [alpha], [beta], [gamma] and [delta]. Values of impact sensitivity of these four crystal polymorphs are different each other and the most stable [beta] is being produced. In this paper, ab initio [beta] calculations (STO-3G) based on the molecular structure in the crystal have been conducted on all of the above HMX crystal polymorphs and the X-ray structural analysis has also been done on the molecular structure of [beta]. As a result, 0.032 has been obtained as the ultimate R index for 734 independent reflections. Concerning the crystal, it is single crystal, its space group is P2[sub 1] /n, and its lattice constants are [alpha] = 6.5347(4), b=11.0296(6),c=7.3549(5), [angstrom] [beta] =102.689(5) [degree], and Zeta=2. When calculations are made on these bases, all energy and impact sensitivity correlate except[gamma]. 21 refs., 6 figs., 7 tabs.

    Basic studies are conducted for the collection of methane from the methane hydrate that exists at levels deeper than 500m in the sea. The relationship between the hydrate generation mechanism and water cluster structure is examined by use of mass spectronomy. It is found that, among the stable liquid phase clusters, the (H2O)21H{sup +} cluster is the most stable. Stable hydrate clusters are in presence in quantities, and participate in the formation of hydrate crystal nuclei. For the elucidation of the nucleus formation mechanism, a kinetic simulation is conducted of molecules in the cohesion system consisting of water and methane molecules. Water molecules that array near methane molecules at the normal pressure is disarrayed under a higher pressure for rearray into a hydrate structure. Hydrate formation and breakdown in the three-phase equilibrium state of H2O, CH4, and CO2 at a low temperature and high pressure are tested, which discloses that supercooling is required for formation, that it is possible to extract CH4 first for replacement by guest molecule CO2 since CO2 is stabler than CH4 at a lower pressure or higher temperature, and that formation is easier to take place when the grain diameter is larger at the formation point since larger grain diameters result in a higher formation temperature. 3 figs.

    The authors have studied on surface treatment of PTFE by a low pressure discharge. It is deduced that excited nitrogen molecules contribute to introduce polar components on the surface. To confirm the speculation, we tried to change population of metastable nitrogen N2 (A{sup 3}{Sigma}u{sup +}) by quenching precursor N2 (B{sup 3}{pi}g), with hydrogen molecule. The decrease of relaxation time which indicates a change of excited molecule and measured by emission spectroscopy using a time after glow method was obtained. As a result, the relaxation times of N2 (B{sup 3}{pi}g) and N2 (A{sup 3}{Sigma}u{sup +}) decreased to 55% and 20% respectively, when mixing ratio of hydrogen was 3%. It was also deduced that hydrogen atom may take a part in a quenching process of N2 (A{sup 3}{Sigma}u{sup +}). 14 refs., 11 figs., 1 tab.

    The formation of a fullerene was simulated using the molecular dynamics method. The clustering process starting from 500 isolated carbon atoms was simulated under nearly equilibrium conditions at Tc=3000 K with a density of 30 times lower than that in our previous study for investigation of the effect of annealing during collisions. The small clusters appeared in this simulation were simpler than those in the previous case; they were grown with a simple chain or ring structure for C{sub n<20}, a 3-dimensional chaotic structure for around C{sub 2040}. Since the density of carbon atoms in the simulation was still high due to the computational limitation, these clusters are expected to have a much longer collision free time in practice. For further evaluation of the effect of annealing, a C60 structure obtained from the simulation was annealed without collision at Tc=2500 K. Through successive organized network transformations known as Stone Wales rearrangement, a perfect fullerene structured C60 was finally formed in about 50 ns. From the viewpoint of the Arrehenius type reaction rate of rearrangement, the high temperature of 2500 K and the time-share of 50 ns for annealing were comparable to experimental conditions. 39 refs., 5 figs.

    As a trial to enhance activity of bioactive peptide, the dendrimeric formation of mastoparan (MP), a wasp venom toxic peptide, was carried out. We synthesized dendrimeric MPs consisting of 2,4 and 8 MP molecules formed on a branching lysine-core, and examined the hemolytic and catecholamine releasing activities and the circular dichroism. The activities of dendrimeric MPs were higher than that of MP and the {alpha}-helical contents increased with the increase of the number of branches in the dendrimers. The most potent dendrimer in hemolytic activity, approximately 8000 times as active as MP, was octameric MP which took 35 % {alpha}-helical content even in an aqueous buffer. Our results indicated that the dendrimeric formation of an amphipathic peptide should be a useful way to obtain highly active peptide as shown already in immunogenicity. (author)

    This paper discusses effects of surface reaction on deactivation of excited molecular oxygen in {sup 1}{Delta}g condition. Gaseous oxygen containing excited oxygen generated by microwave discharge at a concentration of less than 1% is flown into several kinds of tubes to be measured such as quartz tubes (with an inner diameter of about 10 mm), and the light emitting intensity of the excited oxygen was measured upstream and downstream of the tubes to be measured (with in-tube pressure of 1 Torr or 2 Torr) to derive its concentration change. The surface reaction on the tube wall was regarded as a primary reaction, and the concentration change of the excited oxygen in flows in the round tube (attributable to the surface reaction) was analyzed. With respect to effects of tube wall materials on deactivation of the excited molecular oxygen, the surface deactivation probability in the case of using low-activity materials has decreased in the order of Pyrex, PVC, quartz, PFA and PTFE. The surface deactivation probability in the case of using a metallic material, SUS316L, was about 1000 times larger than that in the quartz. 14 refs., 7 figs., 1 tab.

    For understanding of fundamental chemical reactions under a highly non equilibrium condition which is quite often used in plasma processing, the relevant atomic and molecular processes must be clarified. In this study, an analysis of the transition process to the excited state of an oxygen molecule induced by electron collisions in the oxygen plasma has been carried out. First, the electron density distribution in an oxygen molecule has been calculated using the extended Huckel molecular orbital method. Then, the electron potential energy distribution in the transition process to the excited state has been estimated. The electron behavior has been calculated using the estimated unidimensional electron potential energy distribution and unsteady quantum mechanics. As a result, the transition process to the excited state of an oxygen molecule induced by electron collisions and its conditions have been clarified qualitatively. 9 refs., 9 figs.

    By administering in vivo by using jointly with cleaning agent which is a kind of anticancer drug, Z-GlyPhe (Benzyloxycarbonyl-{sup L}-glycyl-{sup L}-phenylalanine) the disruption to the normal cell by the cleaning agent is shielded and has the action in which only the cancer cell is destroyed. Since equilibrium in reaction inclines toward the peptide decomposition side, in this study, the. Yield is about 10% of the some, when this peptide was enzymatically synthesized in. aqueous medium which examined the efficient and connected synthesis of cell disruption shielding peptide precursor (Z-GlyPheOMe) using the biocatalyst action of the enzyme. However, peptide is distributed at the organic solvent phase in the water/biphasic organic-aqueous system, since it is a nonionic material in the molecular structure without leaving group. With the enzyme reaction in water phase, by selectively separating the extraction to organic phase, equilibrium in reaction in water phase was improved, and close 100% high yield was achieved got.

    This study is intended to establish a basic technology for innovative high-efficiency separation membrane materials that can be used in areas in which application of membrane separation has been impossible. The water/ethanol separation membrane (for water selective permeation) and water/acetic acid separation membrane (for water selective permeation) achieved separation coefficient and permeation velocity of the world's highest level. The water/ethanol separation membrane (for ethanol selective permeation), although its separation coefficient is lower than the world's highest performance, has high permeation velocity, providing the performance of the worldwide level as seen from the comprehensive viewpoint. The carbon monoxide/nitrogen separation membrane achieved separation coefficient and permeation velocity of the world's highest level. The oxygen/nitrogen separation membrane requires further enhancement in the permeation velocity and stability. Establishment has been performed on separation technologies for membrane separation of non-water soluble aqueous solutions, optical division by using chiral crown ether, high-performance liquid separation by means of plasma surface treatment, and particle separation. Basic analysis has been advanced also on evaluation technologies for gaseous body separation membrane and liquid separation membrane, of which future progress is expected. (NEDO)

    The test and survey on a next generation coal liquefying catalyst present a new proposal to raise catalytic activity in coal liquefaction, and perform demonstration experiments in a laboratory scale to search for possibility of developing a new coal liquefying catalyst from various viewpoints. To explain, discussions were given on the catalyst to perform the followings: liquefaction under extremely mild conditions by using ultra strong acids not limited only to metals; ion exchange method and swell carrying method to raise catalyst dispersion very highly, enhance the catalytic activity, and reduce the amount of catalyst to be used; mechanism of producing catalyst activating species to further enhance the activity of iron catalysts; and pursuit of morphological change in the activating species. The coal molecule scientific test and survey as the base for commercializing the coal liquefying technology performed the studies on the following items: pretreatment of coal that can realize reduction of coal liquefaction cost; configuration of the liquefaction reaction, liquefying catalysts, hydrocarbon gas generating mechanism, status of catalysts after liquefaction reaction, and reduction in gas purification cost by using gas separating membranes. Future possibilities were further searched through frank and constructive opinion exchanges among the committee members. (NEDO)

    Recently, Ernest Sosa (2007) has proposed two novel solutions to the problem of dream skepticism. In the present paper, I argue that Sosa's first solution falls prey to what I will refer to as the conditionality problem, i.e., the problem of only establishing a conditional---in this case, "if x......, then I am awake," x being a placeholder for a condition incompatible with dreaming---in a context where it also needs to be established that we can know that the antecedent holds, and as such can infer the consequent, i.e., "I am awake." Sosa's second solution in terms of so-called reflective knowledge......, I conclude that Sosa has not solved the problem of dream skepticism....

    The Surgeons OverSeas assessment of surgical need (SOSAS) tool, a population-based survey on surgical conditions in low- and middle-income countries (LMICs), was performed in Sierra Leone and Rwanda. This pilot study in Nepal is the initial implementation of the SOSAS survey in South Asia. A pilot study of SOSAS, modified for Nepal's needs and reprogrammed using mobile data collection software, was undertaken in Pokhara in January 2014. Cluster randomized sampling was utilized to interview 100 individuals in 50 households within two wards of Pokhara, one rural and one urban. The first portion of the survey retrieved demographic data, including household members and time to nearest health facilities. The second portion interviewed two randomly selected individuals from each household, inquiring about surgical conditions covering six anatomical regions. The pilot SOSAS in Nepal was easily completed over 3 days, including training of 18 Nepali interns over 2 days. The response rate was 100 %. A total of 13 respondents had a current surgical need (face 4, chest 1, back 1, abdomen 1, groin 3, extremity 3), although eight reported there was no need for surgical care. Five respondents (5 %) had a current unmet surgical need. The SOSAS pilot study in Nepal was successfully conducted, demonstrating the feasibility of performing SOSAS in South Asia. The estimated 5 % current unmet surgical need will be used for sample size calculation for the full country survey. Utilizing and improving on the SOSAS tool to measure the prevalence of surgical conditions in Nepal will help enumerate the global surgical burden of disease.

    Obstructive sleep apnea (OSA) affects up to 26% of US adults, is often undiagnosed, and increases perioperative morbidity. We hypothesized that patients screened on the day of surgery as moderate/high risk for OSA (S-OSA) present similar perioperative respiratory complications, hospital use, and mortality than patients with previously diagnosed OSA (D-OSA). Second, we hypothesized that both OSA groups have more respiratory complications than No-OSA patients. The electronic medical database from 1 academic and 2 community hospitals was retrospectively queried to identify adults undergoing nonemergent inpatient surgery (January 1, 2012, to December 31, 2014). Based on the day-of-surgery preoperative assessment and STOP-BANG (Snoring, Tiredness, Observed apnea during sleep, high blood Pressure, Body mass index >35, Age >50 years, thick Neck, Gender male) score, they were classified as D-OSA, S-OSA, or No-OSA. Perioperative respiratory events and interventions, hospital use, and mortality were measured. The primary outcome composite (adverse respiratory events [AREs]) included perioperative hypoxemic events and difficult airway management. Hypoxemic event was defined as peripheral saturation of oxygen (SpO2) <90% by continuous pulse oximetry for ≥3 minutes, or if validated and/or manually entered into the medical chart. Hypoxemia was classified as mild (lowest SpO2 86%-89%) or moderate/severe (lowest SpO2 ≤85%). Secondary outcomes included postoperative respiratory interventions, intensive care unit admission, hospital length of stay, and 30-day and 1-year all-cause mortality. Outcomes were compared using linear and logistic regression analyses. A total of 28,912 patients were assessed: 3432 (11.9%) D-OSA; 1546 (5.3%) S-OSA; and 23,934 (82.8%) No-OSA patients. At least 1 ARE was present in 68.0% of S-OSA; 71.0% of D-OSA; and 52.1% of No-OSA patients (unadjusted P < .001), primarily ≥1 moderate/severe hypoxemic event after discharge from the postanesthesia care

Sosa, sulfate and bisulfite methods [1] were applied in the first research step and later they were modified with the lignine extraction process from pine and cedar. Among these, Sosa method showed asthe more efficient method, so, it was used to extract lignine from low rank coal. The extracted lignin was used to prepare lignin-phenol-formaldehide resin and it works as natural fiber binder [2].In the second research step, standarization Sosa method was made [3], were pressure was modified using an pressure reactor (autoclave for a peat sample. Efficiency was improved. The obtained lignine was used to prepare resins such as phenolformaldehide- lignin, resorcinol-formaldehydelignin and polypropilen-lignin. All of them were utilized using sugar cane bagasse as natural fiber. Currently, a third research step is being developed using Sosa method and working with a peat sample.The main purpose, is to modificate the extracted lignin structure by UV radiation (physical methot and with NaOH (Chemical method so the lignin reactivity is improved in the resins production [4] and as result, to get a better quality synthetic wood.

    With an aging global population comes an obligate and substantial burden of noncommunicable disease, especially in low- and middle-income countries. An unknown proportion of this burden is treatable with surgical expertise. For health system planning, this study aimed to estimate the operative needs of individuals older than 50 of age years in Nepal. A 2-stage, cluster randomized, community-based survey was performed in Nepal using the validated Surgeons OverSeas Surgical Assessment Survey (SOSAS). SOSAS collects household demographics and selects household members randomly for verbal, head-to-toe examinations for surgical conditions; moreover, SOSAS also completes a verbal autopsy for deaths in the preceding year. Only respondents older than 50 years were included in the analysis. The survey sampled 1,350 households, totaling 2,695 individuals (97% response rate). Of these, 273 surgical conditions were reported by 507 persons ages ≥ 50 years. Extrapolating, there are potentially 2.1 million people older than 50 years of age with surgically treatable conditions who need care in Nepal (95% confidence interval 1.8-2.4 million; 46,000-62,600 per 100,000 persons). One in 5 deaths was potentially treatable or palliated by surgical care. Although growths or masses (including hernias and goiters) were the surgical condition reported most commonly (25%), injuries and fractures also were common and associated with the greatest disability. Literacy and distance to secondary and tertiary health facilities were associated with lack of care for operative conditions (P Nepal. Low literacy and distance from a capable health facility are the greatest barriers to care. As the global population ages, there is an increasing need to improve surgical services and strengthen health systems to care for this group. Copyright © 2015 Elsevier Inc. All rights reserved.

    Sosa (Proc Addresses Am Philos Assoc 79(2): 7–18, 2005) argues that we should reject the orthodox conception of dreaming—the view that dream states and waking states are “intrinsically alike, though different in their causes and effects” (2005: p. 7). The alternative he proposes is that “to dream is to imagine” (2005: p. 7). According to this imagination model of dreaming, our dreamt conscious beliefs, experiences, affirmations, decisions and intentions are not “real” insofar as they are all ...

    Full Text Available El artículo se refiere a la canción Hermano compuesta por el músico Carlos Guastavino sobre una poesía de Hamlet Lima Quintana. Dedicada al editor Rómulo Lagos, fue grabada por Mercedes Sosa en 1966. Incluida como pista inicial del disco de la cantante tucumana al cual le dio su nombre, la canción constituye una evidencia de la simpatía del compositor con los postulados centrales del Nuevo Cancionero argentino. El trabajo comprende una aproximación a la temática del poema, el análisis musical de la partitura, la puesta en contexto de las circunstancias de composición y difusión y la descripción de la versión grabada por Mercedes Sosa. Aplicando la noción "mundos del arte" de Howard BECKER (1982, se interpreta la red de personas ligadas a la editorial Lagos como un tejido cooperativo que funcionó con eficacia hasta mediados de la década de 1970.

    To determine the unmet anaesthesia need in a low resource region. Surgery and anæsthesia services in low- and middle-income countries (LMICs) are under-equipped, under-staffed, and unable to meet current surgical need. There is little objective measure as to the true extent and nature of unmet need. Without such an understanding it is impossible to formulate solutions. Therefore, we re-examined Surgeons OverSeas (SOSAS) unmet surgical need data to extrapolate unmet anaesthesia need. For the untreated surgical conditions identified by SOSAS, we assigned anaesthetic technique required to carry out the procedure. The chosen anaesthetic was based on common practice in the region. Procedures were categorized into minimal anaesthesia, spinal anæsthesia, regional anaesthesia, ketamine/monitored anaesthesia care (MAC), and general endotracheal anæsthesia (GETA). Ninety-two per cent (687 of 745) of untreated surgical conditions in Sierra Leone would require some form of anaesthesia. Seventeen per cent (125 of 745) would require MAC, 22% (167 of 745) would require spinal anaesthesia, and 53% (395 of 745) would require GETA. Analyses such as this can provide guidance as to the rational and efficient production and distribution of personnel, drugs and equipment.

    Full Text Available Our purpose is to study the limits between reality and fiction in the central chapters of the story of the foundation of the Convento de la Encarnación of Lima by Father Antonio de la Calancha. The convent was founded in 1556 by Leonor de Portocarrero and her daughter Doña Mencía de Sosa, widow of the crown’s traitor Francisco Hernández Girón. Despite the chronicles are consider a «hybrid genre» between literature and history by contemporary critics, Father Calancha’s story is basically historic as it follows the model of humanist histography of the XVI century. We argue that in this model aesthetic values are functional to the interpretation.

    Boron (B) toxicity symptoms are visible in the form of necrotic spots and may worsen the oxidative stress caused by salinity. Hence, the interactive effects of combined salinity and B toxicity stress on antioxidative activities (TAC, LUPO, SOSA, CAT, and GR) were investigated by novel luminescence assays and standard photometric procedures. Wheat plants grown under hydroponic conditions were treated with 2.5 μM H₃BO₃ (control), 75 mM NaCl, 200 μM H₃BO₃, or 75 mM NaCl + 200 μM H₃BO₃, and analysed 6 weeks after germination. Shoot fresh weight (FW), shoot dry weight (DW), and relative water content (RWC) were significantly reduced, whereas the antioxidative activity of all enzymes was increased under salinity compared with the control. High B application led to necrotic leaf spots but did not influence growth parameters. Following NaCl + B treatment, shoot DW, RWC, SOSA, GR, and CAT activities remained the same compared with NaCl alone, whereas the TAC and LUPO activities were increased under the combined stress compared with NaCl alone. However, shoot FW was significantly reduced under NaCl + B compared with NaCl alone, as an additive effect of combined stress. Thus, we found an adjustment of antioxidative enzyme activity to the interactive effects of NaCl and high B. The stress factor "salt" mainly produced more oxidative stress than that of the factor "high B". Furthermore, addition of higher B in the presence of NaCl increases TAC and LUPO demonstrating that increased LUPO activity is an important physiological response in wheat plants against multiple stresses.

    Full Text Available Geographic information system modelling can accurately represent the geospatial distribution of disease burdens to inform health service delivery. Given the dramatic topography of Nepal and a high prevalence of unmet surgical needs, we explored the consequences of topography on the prevalence of surgical conditions. The Nepalese Surgeons OverSeas Assessment of Surgical Need (SOSAS is a validated, countrywide, cluster randomised survey that assesses surgical need in lowand middle-income countries; it was performed in Nepal in 2014. Data on conditions potentially affected by topography (e.g. fractures, hernias, injuries, burns were extracted from the database. A national digital elevation model was used to determine altitude, aspect, slope steepness and curvature of the SOSAS survey sites. Forward stepwise linear regression was performed with prevalence of each surgical condition as the response variable and topographic data as explanatory variables. The highest correlation coefficient was for models predicting hernias and fractures, both explaining 21% of the variance. The model fitted to death due to fall would become significant when an outlier was excluded (P<0.001; R2=0.27. Excluding the outlier yielded a better-fitted model to burn injury (stepwise regression without any explanatory variables. Other models trended towards a correlation, but did not have sufficient power to detect a difference. This study identified slight correlation between elevation and the prevalence of hernias and fall injuries. Further investigation on the effects of topography and geography on surgical conditions is needed to help determine if the data would be useful for directing allocation of surgical resources.

    An estimated 424,000 fatal falls occur globally each year, making falls the second leading cause of unintentional injury-related deaths after road traffic injuries. More than 80% of fall-related fatalities occur in low- and middle-income countries. Data from low-income South Asian countries like Nepal are lacking, particularly at the population level. The aim of this study was to provide an estimate of fall-injury prevalence and the number of fall injury-related deaths countrywide in Nepal and to describe the epidemiology of fall injuries in Nepal at the community level. A countrywide cross-sectional study was performed in 15 of the 75 districts in Nepal using the Surgeons OverSeas Assessment of Surgical Need (SOSAS) survey tool. The SOSAS survey gathers data in 2 sections: demographic data, including the household's access to health care and recent deaths in the household, and assessment of a representative spectrum of surgical conditions, including injuries. Data was collected regarding an individuals' experience of injury including road traffic injuries, falls, penetrating trauma, and burns. Data included anatomic location, timing of injury, and whether health care was sought. If health care was not sought, the reason for barrier to care was included. Descriptive statistics were used to analyze the data. Of 2695 individuals from 1350 households interviewed, 141 reported injuries secondary to falls (5.2%; 95% confidence interval [CI], 4.4%-6.1%), with a mean age of 30.7 years; 58% were male. Falls represented 37.2% of total injuries (n = 379) reported (95% CI, 32.3%-42.3%). Twelve individuals who suffered from a fall injury were unable to access surgical care (8.5%; 95% CI, 4.5%-14.4%). Reasons for barrier to care included no money for health care (n = 3), facility/personnel not available (n = 7), and fear/no trust (n = 2). Of the 80 recent deaths reported, 7 were due to fall injury (8.8%; 95% CI, 3.6%-17.2%), and patients had a mean age of 46 years (SD 22

    Burns are ranked in the top 15 leading causes of the burden of disease globally, with an estimated 265,000 deaths annually and a significant morbidity from non-fatal burns, the majority located in low and middle-income countries. Given that previous estimates are based on hospital data, the purpose of this study was to explore the prevalence of burns at a population level in Nepal, a low income South Asian country. A cluster randomized, cross sectional countrywide survey was administered in Nepal using the Surgeons OverSeas Assessment of Surgical Need (SOSAS) from May 25th to June 12th, 2014. Fifteen of the 75 districts of Nepal were randomly chosen proportional to population. In each district, three clusters, two rural and one urban, were randomly selected. The SOSAS survey has two portions: the first collects demographic data about the household's access to healthcare and recent deaths in the household; the second is structured anatomically and designed around a representative spectrum of surgical conditions, including burns. In total, 1350 households were surveyed with 2695 individuals with a response rate of 97%. Fifty-five burns were present in 54 individuals (2.0%, 95% CI 1.5-2.6%), mean age 30.6. The largest proportion of burns was in the age group 25-54 (2.22%), with those aged 0-14 having the second largest proportion (2.08%). The upper extremity was the most common anatomic location affected with 36.4% of burns. Causes of burns included 60.4% due to hot liquid and/or hot objects, and 39.6% due to an open fire or explosion. Eleven individuals with a burn had an unmet surgical need (20%, 95% CI 10.43-32.97%). Barriers to care included facility/personnel not available (8), fear/no trust (1) and no money for healthcare (2). Burns in Nepal appear to be primarily a disease of adults due to scalds, rather than the previously held belief that burns occur mainly in children (0-14) and women and are due to open flames. This data suggest that the demographics and

La cuestión metodológica es trascendental dentro de la universidad: el proyecto de construcción del Espacio Europeo de Educación Superior plantea cambios profundos en el paradigma docente, debiendo cambiar los roles del profesor y del alumno, dentro y fuera del aula. Para reforzar este argumento, se procedió a la aplicación del Cuestionario de Aprendizaje Cooperativo de Arellano, Navarro y Sosa (2007 a los 692 estudiantes matriculados en primero de Grado de Educación Primaria en el curso 2010/2011. La muestra coincidió con el universo de los estudiantes de primer año en el Grado de Educación Primaria, constituida por un 87% de mujeres y con una edad media de 19 años, lo cual permitió obtener un índice de consistencia interna de 0.83 para el instrumento. Los resultados recalcaron la importancia de potenciar el aprendizaje cooperativo en las aulas universitarias, teniendo en cuenta que son pocas las ocasiones en las que puede ponerse en juego. ABSTRACT: Cooperative learning is one of the main medicines in education: the student takes an active role in their own learning process. Methodological issues are very important within university, since the development project of the European Higher Education Area proposes very profound changes in the educational paradigm, changes in the role of teachers and students inside and outside the classroom. To give force to this argument, the implementation of Cooperative Learning Questionnaire Arellano, Navarro and Sosa (2007 was taken to 692 students enrolled in first grade of primary education in 2010-2011. The sample coincides with the universe of freshmen in the Bachelor of Primary Education, comprising 87% of women with a mean age of 19 years, which yielded an index of 0.83 for internal consistency of the instrument.

    Full Text Available Patriotism is not a viable option for the traditional universalistic moral systems, including Kantian rationalism and especially for consequentialism. The author follows Sosa in claiming that not all forms of consequentialism have to lack 'deontic components'. He follows up with a stronger claim, that not all systems, deontic or consequentialist, have to accept strong universalism that precludes non-instrumental special moral concerns. He presents the main alternatives: (a Dancy's moral particularism; (b Nagel's idea of partiality based on the non-reducible difference between personal and impersonal view points; (c Scheffler's concern with non-voluntary special duties; (d a broad range of philosophies, from Aristotle's to the ethics of care that use non-homogenous models. The author closes by claiming that the non-homogenous models result in viable moral theories. Such theories treat ethics not as a source of moral recommendations to the effect of what should happen in a given situation, but rather as rules of a largely competitive game that adjudicate two things: (1 what each agent should do in a given situation; (2 what constraints should be imposed on the manner in which that moral competition is taking place.

    We dedicate this article to the memory of Sergio de Freitas, FCAV-UNESP, Jaboticabal, São Paulo, Brazil (deceased, 2012). He was an active and enthusiastic Neuropterist and the cherished mentor and friend of Francisco Sosa. Leucochrysa McLachlan is the largest genus in the Chrysopidae, yet it has received relatively little taxonomic attention. We treat two problematic and common Leucochrysa species - Leucochrysa (Leucochrysa) varia (Schneider, 1851) and Leucochrysa (Leucochrysa) pretiosa (Banks, 1910). Both are highly variable in coloration and were described before the systematic importance of chrysopid genitalia was recognized. Recent studies show that these species occur within a large complex of cryptic species and that they have accumulated a number of taxonomic problems. We identify new synonymies for each of the species-for Leucochrysa (Leucochrysa) varia: Leucochrysa (Leucochrysa) ampla (Walker, 1853), Leucochrysa internata (Walker, 1853), and Leucochrysa (Leucochrysa) walkerina Navás, 1913; for Leucochrysa (Leucochrysa) pretiosa: Leucochrysa (Leucochrysa) erminea Banks, 1946. The synonymy of Leucochrysa delicata Navás, 1925 with Leucochrysa (Leucochrysa) pretiosa is stabilized by the designation of a neotype. The following species, which were previously synonymized with Leucochrysa (Leucochrysa) varia or Leucochrysa (Leucochrysa) pretiosa, are reinstated as valid: Leucochrysa (Leucochrysa) phaeocephala Navás, 1929, Leucochrysa (Leucochrysa) angrandi (Navás, 1911), and Leucochrysa (Leucochrysa) variata (Navás, 1913). To help stabilize Leucochrysa taxonomy, lectotypes are designated for Allochrysa pretiosa and Allochrysa variata. Finally, Leucochrysa vegana Navás, 1917 is considered a nomen dubium.

    In low- and middle-income countries (LMICs), an estimated 85% of children do not have access to surgical care. The objective of the current study was to determine the geographic distribution of surgical conditions among children throughout Uganda. Using the Surgeons OverSeas Assessment of Surgical Need (SOSAS) survey, we enumerated 2176 children in 2315 households throughout Uganda. At the district level, we determined the spatial autocorrelation of surgical need with geographic access to surgical centers variable. The highest average distance to a surgical center was found in the northern region at 14.97km (95% CI: 11.29km-16.89km). Younger children less than five years old had a higher prevalence of unmet surgical need in all four regions than their older counterparts. The spatial regression model showed that distance to surgical center and care availability were the main spatial predictors of unmet surgical need. We found differences in unmet surgical need by region and age group of the children, which could serve as priority areas for focused interventions to alleviate the burden. Future studies could be conducted in the northern regions to develop targeted interventions aimed at increasing pediatric surgical care in the areas of most need. Level III.

HCC generally has a more aggressive clinical behavior compared with the other differentiated thyroid cancers, and it is associated with a higher rate of distant metastases. Minimally invasive HCC demonstrates much less aggressive behavior; lesions <4 cm can be treated with thyroid lobectomy alone, and without radioactive iodine (RAI. HCC has been observed to be less iodine-avid compared with other differentiated thyroid cancers; however, recent data have demonstrated improved survival with RAI use in patients with HCC >2 cm and those with nodal and distant metastases. Patients with localized iodine-resistant disease who are not candidates for a wait-and-watch approach can be treated with localized therapies.

    Abstract We dedicate this article to the memory of Sergio de Freitas, FCAV-UNESP, Jaboticabal, São Paulo, Brazil (deceased, 2012). He was an active and enthusiastic Neuropterist and the cherished mentor and friend of Francisco Sosa. Leucochrysa McLachlan is the largest genus in the Chrysopidae, yet it has received relatively little taxonomic attention. We treat two problematic and common Leucochrysa species – Leucochrysa (Leucochrysa) varia (Schneider, 1851) and Leucochrysa (Leucochrysa) pretiosa (Banks, 1910). Both are highly variable in coloration and were described before the systematic importance of chrysopid genitalia was recognized. Recent studies show that these species occur within a large complex of cryptic species and that they have accumulated a number of taxonomic problems. We identify new synonymies for each of the species–for Leucochrysa (Leucochrysa) varia: Leucochrysa (Leucochrysa) ampla (Walker, 1853), Leucochrysa internata (Walker, 1853), and Leucochrysa (Leucochrysa) walkerina Navás, 1913; for Leucochrysa (Leucochrysa) pretiosa: Leucochrysa (Leucochrysa) erminea Banks, 1946. The synonymy of Leucochrysa delicata Navás, 1925 with Leucochrysa (Leucochrysa) pretiosa is stabilized by the designation of a neotype. The following species, which were previously synonymized with Leucochrysa (Leucochrysa) varia or Leucochrysa (Leucochrysa) pretiosa, are reinstated as valid: Leucochrysa (Leucochrysa) phaeocephala Navás, 1929, Leucochrysa (Leucochrysa) angrandi (Navás, 1911), and Leucochrysa (Leucochrysa) variata (Navás, 1913). To help stabilize Leucochrysa taxonomy, lectotypes are designated for Allochrysa pretiosa and Allochrysa variata. Finally, Leucochrysa vegana Navás, 1917 is considered a nomen dubium. PMID:23805050

    Objective Despite the tremendous disability and mortality caused by traumatic injuries worldwide, there is a relative dearth of information on the burden of injuries in developing countries. In an effort to document the surgical burden of disease in Sierra Leone, a nationwide survey was conducted utilizing the Surgeons OverSeas Assessment of Surgical Need (SOSAS) tool. Here, we report the injury data from this study with the aim to (1) provide an estimate of injury prevalence, (2) determine the mechanisms of injury, and (3) evaluate the degree of injury related deaths. Methods A population-based household survey was conducted in Sierra Leone in 2012. Participants were selected using a two-stage random sampling method, which generated a target population of 3750 participants across the 14 districts of Sierra Leone. Frequency distributions of mechanisms of injury based on age, sex, and urban versus rural residence were computed, and bivariate logistic regression models used to determine associations between sociodemographic factors and injury patterns. Results Data was analyzed from 1,843 households and 3,645 respondents, representing a response rate of 98.3%. Four hundred and fifty-two respondents (12.4%) reported at least one traumatic injury in the preceding year. Falls were the most common cause of non-fatal injuries, accounting for over 40% of injuries. The extremities were most commonly injured (55% of injuries) regardless of age or sex. Although motor vehicle related injuries were the 4th most common cause of injury overall, they were the leading cause of injury related deaths, accounting for almost 6% of fatal injuries. Conclusion This study provides baseline data on the burden of traumatic injuries in one of the world's poorest nations. In addition to injury prevention measures, immediate strategies to address current healthcare deficits are urgently needed in these resource poor areas. This report is an Original Article with Level I evidence. PMID:23325317

    2014-07-01

    We present the first results of a long-term observational campaign focused on the detection of activity in selected asteroids and centaurs. Our observational targets are near-Earth asteroids in cometary orbits (cf. [2]), the so called ''main-belt comets'' or ''active asteroids'' (well-known objects as well as potential candidates), and bright centaurs with good orbits, all close to their perihelion passages. In those objects with a former detection of activity, our aim is to contribute to a better physical knowledge of them, and determine, for instance, if the observed activity is transient or permanent. To achieve our goals, we analyzed CCD-filtered images of each observable target acquired with the 2.15-m telescope ''Jorge Sahade'' at CASLEO (San Juan, Argentina), during two runs of three consecutive nights each (during August 2013 and January 2014, respectively). Our study will be completed by future runs with the same instrumentation already assigned to our campaign. As preliminary results, we observed activity in the main-belt comets P/2013 P5 (PANSTARRS) and 133P/(7968) Elst-Pizarro. We also observed the main-belt comet (596) Scheila, which showed an unequivocally stellar appearance. We observed the main-belt comet candidate (3646) Aduatiques (cf. [1]), and noticed in this object a curious feature whose connection to some kind of activity is not well determined yet. We also observed the near-Earth asteroid in cometary orbit 2006 XL_5 (cf. [3]), and the centaurs (281371) 2008 FC_{76}, (332685) 2009 HH_{36}), (382004) 2010 RM_{64}, 2010 XZ_{78}, and 2011 UR_{402}. We have not detected activity in these objects, but an improved analysis is still in progress. %Corresponding author: Andrea Sosa (asosa@fisica.edu.uy)

    Full Text Available David Aguiar-Bujanda, María Jesús Blanco-Sánchez, María Hernández-Sosa, Saray Galván-Ruíz, Samuel Hernández-Sarmiento Department of Medical Oncology, Hospital Universitario de Gran Canaria Doctor Negrín, Las Palmas de Gran Canaria, Spain Abstract: Rituximab is an IgG1, chimeric monoclonal antibody specifically designed to recognize the CD20 antigen expressed on the surface of normal and malignant B-lymphocytes, from the B-cell precursor to the mature B-cells of the germinal center, and by most neoplasms derived from B-cells. After 2 decades of use, rituximab is firmly positioned in the treatment of follicular lymphoma (FL, both in the front line and in the relapsing disease, improving previous results by including it in classical chemotherapy regimens. However, the pharmacology of rituximab continues to generate controversial issues especially regarding the mechanisms of action in vivo. The contribution of rituximab as a maintenance treatment in FL has been significant progress in the management of this disease without an increase in side effects or a decrease in the quality of life of patients. With the widespread use of rituximab, there are new security alerts and side effects not previously detected in the pivotal trials that clinicians should learn to recognize and manage. In this article, we will review the pharmacokinetics and pharmacodynamics of rituximab, the management issues in the treatment of advanced FL focusing on maintenance rituximab, its long-term efficacy and safety profile, and its effect on the quality of life.

  15. Oxidation of SO2 by stabilized Criegee intermediate (sCI radicals as a crucial source for atmospheric sulfuric acid concentrations

    2013-04-01

    Full Text Available The effect of increased reaction rates of stabilized Criegee intermediates (sCIs with SO2 to produce sulfuric acid is investigated using data from two different locations, SMEAR II, Hyytiälä, Finland, and Hohenpeissenberg, Germany. Results from MALTE, a zero-dimensional model, show that using previous values for the rate coefficients of sCI + SO2, the model underestimates gas phase H2SO4 by up to a factor of two when compared to measurements. Using the rate coefficients recently calculated by Mauldin et al. (2012 increases sulfuric acid by 30–40%. Increasing the rate coefficient for formaldehyde oxide (CH2OO with SO2 according to the values recommended by Welz et al. (2012 increases the H2SO4 yield by 3–6%. Taken together, these increases lead to the conclusion that, depending on their concentrations, the reaction of stabilized Criegee intermediates with SO2 could contribute as much as 33–46% to atmospheric sulfuric acid gas phase concentrations at ground level. Using the SMEAR II data, results from SOSA, a one-dimensional model, show that the contribution from sCI reactions to sulfuric acid production is most important in the canopy, where the concentrations of organic compounds are the highest, but can have significant effects on sulfuric acid concentrations up to 100 m. The recent findings that the reaction of sCI + SO2 is much faster than previously thought together with these results show that the inclusion of this new oxidation mechanism could be crucial in regional as well as global models.

    The Air Force Research Laboratory (AFRL) - Sensors Directorate has developed the Blue Guardian program to demonstrate advanced sensing technology utilizing open architectures in operationally relevant environments. Blue Guardian has adopted the core concepts and principles of the Air Force Rapid Capabilities Office (AFRCO) Open Mission Systems (OMS) initiative to implement an open Intelligence, Surveillance and Reconnaissance (ISR) platform architecture. Using this new OMS standard provides a business case to reduce cost and program schedules for industry and the Department of Defense (DoD). Blue Guardian is an early adopting program of OMS and provides much needed science and technology improvements, development, testing, and implementation of OMS for ISR purposes. This paper presents results and lessons learned under the Blue Guardian Project Shepherd program which conducted Multi-INT operational demonstrations in the Joint Interagency Task Force - South (JIATF-S) and USSOUTHCOM area of operations in early 2016. Further, on-going research is discussed to enhance Blue Guardian Multi-INT ISR capabilities to support additional mission sets and platforms, including unmanned operations over line of sight (LOS) and beyond line of sight (BLOS) datalinks. An implementation of additional OMS message sets and services to support off-platform sensor command and control using OMS/UCI data structures and dissemination of sensor product data/metadata is explored. Lastly, the Blue Guardian team is working with the AgilePod program to use OMS in a full Government Data Rights Pod to rapidly swap these sensors to different aircraft. The union of the AgilePod (which uses SOSA compliant standards) and OMS technologies under Blue Guardian programs is discussed.

  18. Utilization of flavonoid compounds from bark and wood: a review.

    2015-03-01

    Flavonoid compounds, which are extracted from bark and wood and used commercially, are flavan 3-ols as monomers and their polymers, which are called "condensed tannins". Reactions of the condensed tannins with formaldehyde are the basis for wood adhesives. In the late 1940s, tannin research for wood adhesives was begun and the world-first commercial use of wattle tannin from black wattle (Acacia mearnsii) bark as wood adhesives occurred in Australia in the 1960s. In addition, wattle tannin-based adhesives were further developed in South Africa and the uses of these adhesives have been continuing to date. The success of wattle tannin in wood adhesives is demonstrated by the collaboration of the ACIAR with the CAF in the early 1990s. Although radiata pine bark (Pinus radiata) could be a useful resource for the production of wood adhesives, three problems prevented its use in this application: low extractive yields from the bark, variable quality of the tannin extracts and excessive viscosity of the formulated tannin adhesives. In order to overcome these problems, various extraction methods have been proposed. Studies on tannin adhesives from bark of other pine species are also described. Furthermore, the use of the tannin in the bark without extraction is described as "bark adhesives" from radiata pine and black wattle. The use of radiata tannin without formaldehyde for moulded wood products is also described. Owing to the strong antioxidant activity of flavonoid compounds, bark extracts from French maritime pine (Pinus pinaster, synonym P. maritima) and radiata pine have been commercialized as nutritional supplements: Pycnogenol and Enzogenol, respectively. The background and the development of Pycnogenol and the basic difference in the preparation processes between Pycnogenol and Enzogenol are described. On the basis of the discovery that the SOSA value for wattle tannin is approximately 10 times that of extracts from pine bark supplements (Pycnogenol and Enzogenol

  19. Formalization of the engineering science discipline - knowledge engineering

    Science.gov (United States)

    Peng, Xiao

    Knowledge is the most precious ingredient facilitating aerospace engineering research and product development activities. Currently, the most common knowledge retention methods are paper-based documents, such as reports, books and journals. However, those media have innate weaknesses. For example, four generations of flying wing aircraft (Horten, Northrop XB-35/YB-49, Boeing BWB and many others) were mostly developed in isolation. The subsequent engineers were not aware of the previous developments, because these projects were documented such which prevented the next generation of engineers to benefit from the previous lessons learned. In this manner, inefficient knowledge retention methods have become a primary obstacle for knowledge transfer from the experienced to the next generation of engineers. In addition, the quality of knowledge itself is a vital criterion; thus, an accurate measure of the quality of 'knowledge' is required. Although qualitative knowledge evaluation criteria have been researched in other disciplines, such as the AAA criterion by Ernest Sosa stemming from the field of philosophy, a quantitative knowledge evaluation criterion needs to be developed which is capable to numerically determine the qualities of knowledge for aerospace engineering research and product development activities. To provide engineers with a high-quality knowledge management tool, the engineering science discipline Knowledge Engineering has been formalized to systematically address knowledge retention issues. This research undertaking formalizes Knowledge Engineering as follows: 1. Categorize knowledge according to its formats and representations for the first time, which serves as the foundation for the subsequent knowledge management function development. 2. Develop an efficiency evaluation criterion for knowledge management by analyzing the characteristics of both knowledge and the parties involved in the knowledge management processes. 3.

    Given the geographic, demographic, and historical importance of Cuba vis-a-vis the dissemination of language and culture throughout the Hispanic Caribbean, one would naturally anticipate a larger corpus of scientifically-noteworthy linguistic publications on Cuban Spanish, which is far from the actual case. Moreover, the gemination of an onset positionally subsequent to the deletion of a syllable-final liquid (generally termed liquid gemination in the literature) has been repeatedly claimed yet remarkably unsubstantiated as a pervasive characteristic of Cuban Spanish, particularly of the western dialect region (cf. Alfaraz (2000, 2007, 2008), Casanellas and Alamo (1985), Choy Lopez (1985, 1988, 1989), Costa Sanchez (1987), Darias Concepcion (2001, 2005), Dohotaru (2002, 2007), Figueroa Esteva and Dohotaru (1994), Garcia Perez (2006), Garcia Riveron (1991), Haden and Matluck (1973, 1974, 1977), Isbǎsescu (1965, 1968), Lamb (1968), Levina (1970), Montero Bernal (1990, 2002, 2007a, b), Ringer Uber (1986), Ruiz Hernandez (1978), Sosa (1974), Terrell (1976), Trista and Valdes (1978), Valdes Acosta (1980), and Vera Riveron (2000)). As a result, in the interest of supplementing all antecedent work concerning the allophony of final liquids as well as affording a more descriptively-precise account of the allophony of word-internal, post-nuclear /l/ and /[Special character omitted]/ in Cuban Spanish in addition to expressly addressing the need for empirical data-collection and analysis processes, the present investigation was specifically designed and implemented to acoustically investigate the phenomenon of gemination as it is purported to occur in the Spanish of the region of Havana, Cuba: more specifically, (1) to acoustically examine the qualitative and quantitative patternings of post-nuclear /l/ and /[Special character omitted]/ within the word; and (2) to statistically evaluate the relationship between gemination and eight independent variables: gender, age group

    Road traffic injury has emerged as a leading cause of mortality, contributing to 2·1% of deaths globally and is predicted to be the third highest contributor to the global burden of mortality by 2020. This major public health problem disproportionately affects low-income and middle-income countries, where such incidents are too often underreported. Our study aims to explore the epidemiology of road traffic injurys in Nepal at a population level via a countrywide study. The Surgeons OverSeas Assessment of Surgical Need (SOSAS) tool, a cluster randomised, cross-sectional nationwide survey, was conducted in Nepal between May 25, and June 12, 2014. Two-stage cluster sampling was performed: 15 of 75 districts were chosen randomly proportional to population; within each district, after stratification for urban and rural, and three clusters were randomly chosen. Questions were structured anatomically and designed around a representative spectrum of surgical conditions. Road traffic injury-related results were reported. 1350 households and 2695 individuals were surveyed with a response rate of 97%. 75 road traffic injuries were reported in 72 individuals (2·67% [95% CI 2·10-3·35] of the study population), with a mean age of 33·2 years (SD 1·85). The most commonly affected age group was 30-44 years, with females showing significantly lower odds of sustaining a road traffic injury than men (crude odds ratio 0·29 [95% CI 0·16-0·52]). Road traffic injuries composed 19·8% of the injuries reported. Motorcycle crashes were the most common road traffic injuries (48·0%), followed by car, truck, or bus crashes (26·7%), and pedestrian or bicycle crashes (25·3%). The extremity was the most common anatomic site injured (74·7%). Of the 80 deaths reported in the previous year, 7·5% (n=6) were due to road traffic injuries.

    Introducción: la alimentación constituye el pilar fundamental del soporte nutricional de los pacientes hospitalizados. Evaluar el grado de aceptación de la dieta es imprescindible en aras de combatir la desnutrición hospitalaria.Objetivos: a) determinar el grado de satisfacción de los pacientes en relación con las dietas; y b) analizar posibles variables asociadas a un grado de satisfacción mayor (apetito y tipo de dieta).Material y métodos: estudio descriptivo de corte transversal. Se emplea una encuesta de 17 preguntas con datos sociodemográficos, datos cualitativos, así como la valoración general del paciente. Se comparó el grado de satisfacción global en función del apetito y el tipo de dieta (terapéutica vs.basal; con sal vs.sosa) (Test no paramétric o Krustal-Wallis y T-Student para muestras independientes, respectivamente).Resultados: mil cuatrocientos trece pacientes. Edad: 53,9 ± 19 años; 51,3% mujeres. Dieta terapéutica (34,9%). Solo el 39,4% tomó dieta con sal. El 66,8% refirió ingresos previos. La alimentación del hospital para un 43% de pacientes fue ''como esperaba'', mientras que para un 44,1% fue ''mejor de lo que esperaba''. El horario de comidas era adecuado (89,1%) y el tiempo para comer, suficiente (96,4%). En cuanto a las características de la comida servida, consideraron como buenas o muy buenas la misma el porcentaje reflejado: sabor/gusto (56.3%), olor (65,5%), cocinado (69,2%), presentación (80,4%), tamaño de ración (75,9%), calidad (73%), cantidad (77,9%), variedad (67,6%), temperatura (70,4%). La valoración global de la alimentación en una escala de 1 a 10 fue de 6,8 ± 2,3. El apetito se asoció a un aumento significativo de la satisfacción global alimentaria del paciente (p dieta o la presencia de sal en la misma no se asociaron a un aumento significativo de la satisfacción con la dieta de los pacientes (p = 0,99 y 0,35, respectivamente).Conclusiones: aunque el grado de satisfacción de la dieta de nuestro

Multiple drugs have been used in their treatment. Silver sulfadiazine (SSD and silver nanocrystals (SNC are among the most used. The purpose of this research was to compare the effectiveness of SSD and SNC regarding the wound granulation rate, treatment time, antibiotic effect, and treatment cost and to determine the frequency of these lesions in participants of this research.Methods: Data were collected from 50 patients with soft tissue lesions in the Regional University Hospital José María Cabral y Báez (HRUJMCB, in Santiago, Dominican Republic. This study was approved by the bioethics committee of the Pontifical Catholic University Madre and Maestra (PUCMM and the HRUJMCB. Patients were followed up from August 2015 to February 2016. SPSS Statistics program was used to calculate Chi square and assess statistical significance.Results: Fifty patients were included in this study, of whom 56% had diabetic foot ulcers, 22% had vascular ulcers, and 22% had pressure ulcers. In total, 42% of the patients were treated with SSD and 58% with SNC. Granulation rate was 71.4% for SSD and 89.6% for SNC, and positive antibiotic effect was 15.9% for SSD and 25.9% for SNC.

    termico generado al interior de las edificaciones por las inadecuadas propiedades de los materiales de construccion, se desarrollaron en este trabajo filtros solares con base en hierro por medio de los cuales se logra un control selectivo de la radiacion solar que se transmite a traves de las ventanas. Estos filtros solares consisten en peliculas delgadas de FeO depositadas sobre sustratos de vidrio cal-sosa (el mas usado en nuestro pais para las edificaciones) de 600x300x3 mm, por medio de la tecnica de sputtering asistida con radiofrecuencia y magnetrones planos, partiendo de un blanco de hierro puro de 127x254 mm y usando un plasma de argon. Para obtener el grado de oxidacion deseado en el hierro, pequenas muestras (45 x 22 mm) fueron sometidas a un proceso de calentamiento en una atmosfera reductora constituida de 50% H{sub 2} + 50% N{sub 2}, durante un periodo de tiempo de 10 minutos a una temperatura de 400 C. Los filtros solares con base en FeO presentan una transmisividad de 30.2% para el intervalo visible del espectro electromagnetico (radiacion con longitud de onda de 380-780 nm), y de 39.9% para el infrarrojo cercano (radiacion con longitud de onda de 780-2500 nm); mientras que su reflectividad es de 17.5 y 19%, para los intervalos visibles e infrarrojo cercano del espectro electromagnetico respectivamente. Se realizo una simulacion, a traves del software Energy 10, del comportamiento energetico de una casa-habitacion cuando utilizan en las ventanas vidrios simples (una lamina) tipo cal-sosa, asi como tambien cuando esta misma edificacion usa en las ventanas los filtros solares con base en FeO desarrollados. Ambos casos se comparan obteniendose asi los posibles ahorros de energia por el uso de dichos filtros solares en las ventanas. Las simulaciones fueron llevadas a cabo para diferentes localidades del pais, obteniendose que los filtros solares con base en FeO desarrollados, permiten ahorros de energia principalmente por concepto de acondicionamiento de aire
