Płaczcie – umarł Pan… Nazwy własne we wczesno-barokowym poemacie pasyjnym (na przykładzie Pamiątki krwawej ofiary Pana Zbawiciela naszego Jezusa Chrystusa Abrahama Rożniatowskiego)
Authors: Rejter Artur
Published: August 2017

The article is dedicated to description of proper names functions in chosen narrative poem of Passion literature of Polish Baroque. Analyzed proper names in Pamiątka krwawej ofiary Pana Zbawiciela naszego Jezusa Chrystusa (1610) by Abraham Rożniatowski are mainly connected with metaphysical sphere of culture, majority of them is conventional, primarily drawn from Bible. The main function of proper names is to describe the Passion in influential way and to show the people how grievous and savage it was. The onomastic field of the narrative poem is strictly related to religious cult of Kalwaria Zebrzydowska popular in Poland in Baroque times.
Entwicklung eines Kuppelwinkelreglers für
GuD-Einwellen-Kraftwerke
Authors: Zimmer Gerta , Pieper Daniel , Bennauer Martin
Published: August 2017

Eine Hauptbauform im
Bereich der großen Kraftwerke ist die GuD (Gas- und
Dampf) Konfiguration. Dabei wird die Abhitze von einer
oder mehreren Gasturbinen verwendet, um Dampf zu
erzeugen und damit eine nachgeschaltete Dampfturbine zu
betreiben. Bei einem
GuD-Einwellen-Kraftwerk wird ein
einziger Generator sowohl durch die Gas- als auch durch
die Dampfturbine angetrieben. Bei dieser Bauform sind
Gasturbine und Generator starr gekoppelt, die
Dampfturbine überträgt das Moment hingegen über eine
synchronisierende,
selbst-schaltende Kupplung.

Beim Hochfahren kuppelt die Dampfturbine normalerweise in einem beliebigen
Winkel relativ zur
Gasturbinen-/Generatorwelle. Es
gibt nun Turbinenstränge, bei denen aus
betrieblichen Gründen ein bestimmter Winkelbereich bevorzugt
wird. Aus diesem Grund wurde eine Regelung
entwickelt, die das Einkuppeln in einem definierten
Winkelbereich ermöglicht.

Die Stabilität und Robustheit gegenüber Störgrößen
(schwankende Netzfrequenz) und Parameterunsicherheiten wurde zunächst
simulationsbasiert untersucht. Das Konzept wurde
leittechnisch umgesetzt und die Performance des Reglers in
Hardware-in-the-loop-Tests
validiert. Auch die darauf folgende Erstimplementierung
in einem niederländischen Kraftwerk war erfolgreich,
die vorgegebene Genauigkeit konnte gesichert erreicht
werden.

Dieser Beitrag zeigt die Entwicklungsschritte, die
systemtechnisch vorgegebenen Randbedingungen sowie Auswertungen der
erfolgten Implementierungen.
Über die Existenz einer separierten Koordinatendarstellung für unteraktuierte mechanische Systeme

Die Modellbildung unteraktuierter mechanischer Systeme führt auf ein System nichtlinearer verkoppelter
Differentialgleichungen zweiter Ordnung. Die rechte Seite beschreibt dabei die Wirkung externer (verallgemeinerter)
Kräfte, d. h. des Systemeingangs, wobei dessen Komponenten über eine im Allgemeinen konfigurationsabhängige
Matrix den einzelnen Differentialgleichungen zugeordnet werden. In der Literatur wird allerdings oft angenommen, dass die
Konfigurationskoordinaten und der Eingang so gewählt werden können, dass sich eine Zerlegung in ein vollständig aktuiertes
und ein nichtaktuiertes Teilsystem ergibt. Dieser Beitrag stellt ein Kriterium vor, wann eine solche Koordinatenwahl
möglich ist. Dazu werden die Theorie der Differentialformen und der Satz von Frobenius herangezogen.
Auf die praktische Auswertung des Kriteriums wird anhand von drei Beispielen eingegangen.
Simultaneous Carbon Capture and Reuse Using Catalytic Membrane Reactor in Water-Gas Shift Reaction
Authors: Saw Shuey Zi , Nandong Jobrun
Published: August 2017

Hydrogen (H2) has been recognized as one of the attractive energy carriers due to its clean and environmentally friendly characteristics where the burning of H2 as a fuel produces zero waste emission. Water-gas shift reaction (WGSR) has been accepted as one promising pathway for producing hydrogen. Recently, membrane technology has emerged as a new way to improve high-purity H2 production via the WGSR. A substantial amount of research works has so far focussed on the production of H2 alone while often neglecting the emission of carbon dioxide (

), a greenhouse gas that is known to be the culprit responsible for global warming. Addressing the conflicting issues between clean H2 fuel and environmentally adverse

$CO_2$

C

emission requires a systematic engineering approach to carbon capture to be incorporated directly into H2 production plant. In view of this, the reuse of

$CO_2$

can be implemented by incorporating the dry methanation reaction. In the proposed reuse strategy, the WGSR uses carbon monoxide (CO) and water as the reactants while the dry methanation reaction uses

and methane (CH4) to produce CO and H2. Based on two case studies of industrial plants, this paper presents a rigorous evaluation of the technical and economic feasibility of the implementation of this reuse strategy by using H2 selective membrane reactor (MR). Upon extensive analysis of different strategies with and without carbon capture technology, it is found that with the proposed carbon capture strategy, the industrial plants show positive improvement in terms of both technical and economic performances.

Authors: Abang Sariah , Anisuzzaman S. M. , Bono Awang , Krishnaiah D. , Afikah N. A.
Published: August 2017

Major components of triglycerides in palm oil are palmitic acid, oleic acid, and linoleic acid, in which the presence of these components effects the final purity of a biodiesel. Since reaction process and type of catalyst influence the composition of the free fatty acid (FFA) ASPEN HYSYS was used to simulate a biodiesel production process. Furthermore, higher yield of biodiesel was desired to increase its efficiency as fuel application. Palm oil was taken as the raw material at different components of FFA wt% by using sulphated zirconium (SZ) as the catalyst. Three simulations of biodiesel production processes were performed using ASPEN HYSYS based on 99 % of conversion factor to determine the energy consumption and the results were compared. The conversion factor for each component and the mixture of all of the components was discussed. Results showed that triolein with 0.12 wt% of oleic acid produced 99.75 % of biodiesel, while tripalmitin with 0.5 wt% of palmitic acid is the most abundant FFA in palm oil producing 99.67 % of biodiesel. The total energy consumption in the three processes were different because, different types of feedstocks and unit operations arrangements have been used.

Published: August 2017

A double acceptance sampling plan (DASP) based on truncated life tests is
suggested in this paper when the lifetime of a product follows the
exponentiated generalized inverse Rayleigh distribution (EGIR). For a fixed
value of the consumer’s confidence level, the minimum sample sizes of the
first and second samples needed to ensure the specified mean life are
obtained. The operating characteristic values according to the different
quality levels are obtained and the minimum ratios of the mean life to the
specified life are calculated. The important tables based on the suggested
DASP are calculated and illustrated.

Authors: Atıci Emine , Mogulkoc Rasim , Baltaci Abdulkerim Kasım , Menevse Esma
Published: August 2017

Background

Changes in thyroid hormone concentrations may affect adiponectin concentrations through various mechanisms. A molecule released primarily from the fat cells adiposities; adiponectin has important effects on the regulation of body weight.

Aim

The present study aimed to explore the effects of experimental thyroid dysfunction and its treatment on nesfatin-1 and adiponectin levels in rats.

Methods

The study included 40 adult male Sprague-Dawley rats which were grouped as follows: (1) control; (2) hypothyroidism [hypothyroidism was induced by intraperitoneal injection of 10 mg/kg/day propylthiouracil (PTU) for 3 weeks]; (3) hypothyroidism + thyroxine group [after hypothyroidism was induced by 2-week PTU injection, they were treated with high-dose L-thyroxine (1.5 mg/kg/day) for 1 week]; (4) hyperthyroidism [hyperthyroidism was induced by 3-weeks’ thyroxine injection (0.3 mg/kg/day)]; (5) hyperthyroidism + PTU (after hyperthyroidism was induced by 2-weeks’ thyroxine injection, the animals were given 10 mg/kg/day PTU for 1 week). Blood samples taken at the end of the study were analyzed to measure nesfatin-1 and adiponectin levels.

Results

It was found that nesfatin-1 levels increased in hypothyroidism, while adiponectin levels decreased (p < 0.001). In experimental hyperthyroidism, on the other hand, both nesfatin-1 and adiponectin levels were found significantly elevated (p < 0.001).

Conclusion

The results of the study indicate that nesfatin-1 and adiponectin levels were modified considerably in hypo- and hyperthyroidism, whereas with the restoration of the thyroid function, modified hormone levels went back to normal.
La-, Mn- and Fe-Doped Zirconia Washcoats Deposited on Monolithic Reactors via Sol-Gel Method: Characterization and Evaluation of their Mass Transfer Phenomena and Kinetics in Trichloroethylene Combustion
Authors: Rivera De la Rosa Javier , Lucio-Ortiz Carlos J , Pedroza-Solís Celia D , De Haro-Del Rio David , García Tomás Hernández
Published: August 2017

La-, Mn- and Fe-doped ZrO2 was synthesized using the sol-gel method, washcoated on cordierite monoliths and used in trichloroethylene (TCE) combustion. A sol from sol-gel synthesis method was used to obtain the zirconia washcoatings. The washcoatings deposited on the cordierite monolith materials were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectroscopy and N2 physisorption measurements, being the crystalline phase determination the most correlate with the catalytic activity. The washcoat properties were correlated to their performance in trichloroethylene combustion. The catalytic washcoatings contained a mixture of crystalline tetragonal ZrO2 and monoclinic ZrO2, and the monoclinic phase exhibited strong interactions with the α-cordierite crystalline phase. For the kinetic tests, the mass transfer into the washcoated monolith channels was evaluated using a recently developed model for the internal mass transfer coefficients for diffusion and reactions in catalytic monoliths. This model involves three resistances. In a plot of the overall resistance as function of the Thiele modulus was determinate that he reaction occurred in the kinetically controlled regime. The kinetic data were fit to two Langmuir–Hinshelwood (LH) models, and the reaction rate was fitted as a function of the trichloroethylene inlet concentration. The adsorption parameters obtained with both LH models were validated based on thermodynamic criteria for the changes in the standard enthalpy of adsorption(${\Delta}H_{ads}^0$) and standard total entropy of adsorption (${\Delta}S_{ads}^0$). It was found that adsorbed TCE and oxygen atoms should be more mobile over the catalyst, which had a higher proportion of tetragonal phase than monoclinic phase of zirconia. The La, Fe-doped catalyst exhibited the highest activity, mainly due the presence of tetragonal zirconia.

Anisotropic excitation of surface plasmon polaritons on a metal film by a scattering-type scanning near-field microscope with a non-rotationally-symmetric probe tip

Published: August 2017

We investigated the excitation of surface plasmon polaritons on gold films with the metallized probe tip of a scattering-type scanning near-field optical microscope (s-SNOM). The emission of the polaritons from the tip, illuminated by near-infrared laser radiation, was found to be anisotropic and not circularly symmetric as expected on the basis of literature data. We furthermore identified an additional excitation channel via light that was reflected off the tip and excited the plasmon polaritons at the edge of the metal film. Our results, while obtained for a non-rotationally-symmetric type of probe tip and thus specific for this situation, indicate that when an s-SNOM is employed for the investigation of plasmonic structures, the unintentional excitation of surface waves and anisotropic surface wave propagation must be considered in order to correctly interpret the signatures of plasmon polariton generation and propagation.
Coating strategies for atomic layer deposition
Authors: Hu Liang , Qi Weihong , Li Yejun
Published: August 2017

Atomic layer deposition (ALD) is a vapor phase technique capable of producing a variety of materials. It consists of the alternation of separate self-limiting surface reactions, which enables accurate control of film thickness at the Angstrom level. ALD becomes a powerful tool for a lot of industrial and research applications. Coating strategies are the key for ALD; however, there are few systematic reviews concerning coating strategies for ALD. This review provides a detailed summary of state-of-the-art coating strategies in ALD, emphasizing the recent progress in the fabrication of novel nanostructures. The progress in coating strategies is reviewed in three parts: template-assisted preparation of low-dimensional nanomaterials and complex nanostructures; surface treatments, including the surface activation and the surface blocking ways; enhanced reactor, such as plasma and fluid bed reactor, and improved growth method such as the ABC-type model. In addition, we also discussed the challenges facing the coating method for ALD.
Mechanical and morphological properties of modified halloysite nanotube filled ethylene-vinyl acetate copolymer nanocomposites
Authors: Padhi Suvendu , Achary P. Ganga Raju , Nayak Nimai C.
Published: August 2017

Halloysite nanotubes (HNTs) were modified by γ-methacryloxypropyltrimethoxysilane (γ-MPS) as it interacts with the aluminol and silanol groups of HNTs present at the edges and surfaces of HNTs. The polymer composites were prepared by means of the solution casting method with ethylene-vinyl acetate (EVA) copolymer having 45% vinyl acetate (VA) content with different weight percent of modified HNTs (m-HNTs). The modification of the HNTs by γ-MPS increases the interfacial and inter-tubular interactions and the degree of dispersion of the HNTs within the EVA matrix which manifest from increase in crosslinking density. The mechanical properties such as tensile strength, tensile modulus and tear strength of nanocomposites were found to increase because of m-HNT. The glass transition temperature (Tg) and the crystalline percentage decreases for EVA/m-HNT nanocomposites were due to the strong interaction between EVA matrix and filler. Also, the EVA/m-HNT nanocomposites exhibited better thermal stability due to the strong inter-tubular interaction.
Negative concord in Quebec French
Authors: Labelle Marie
Published: August 2017

It is argued that there are two types of asymmetric negative concord languages: in languages like Spanish and Italian, negative concord results from a purely formal agreement relation between the negation and a negative concord item. In Quebec French, in addition to this purely formal licensing, there is a negative dependency relation between both items, which form two segments of a discontinuous negative quantifier. This accounts for the following differences. While Spanish, Italian and Quebec French reject negative concord between a subject negative expression and the negation, in Quebec French, negative concord with the negation becomes possible when the clause contains a postverbal negative expression in addition to a preverbal one. Moreover, in Quebec French, but not in Spanish or Italian, negative concord is blocked across a quantifier meaning

de la Motte, SJ, Gribbin, TC, Lisman, P, Murphy, K, and Deuster, PA. A systematic review of the association between physical fitness and musculoskeletal injury risk: part 2—muscular endurance and muscular strength. J Strength Cond Res 31(11): 3218–3234, 2017—This is a systematic review and evaluation of the current evidence on the association between both muscular endurance (ME) and muscular strength (MS) and musculoskeletal injury (MSK-I) risk in military and civilian populations. MEDLINE, EBSCO, EMBASE, and the Defense Technical Information Center were searched for original studies published from 1970 through 2015 which examined associations between physical fitness (ME and MS) and MSK-I in military or civilian populations. Methodological quality and strength of the evidence were determined following criteria adapted from previously published systematic reviews. Forty-five of 4,229 citations met our inclusion criteria. Although results for some tests did vary by sex, taken together, our primary findings indicate there is (a) a strong evidence that poor performance in a push-up test is associated with MSK-I risk; (b) moderate evidence that poor performance in sit-up test is associated with MSK-I risk; (c) moderate evidence that isokinetic ankle and knee flexion strength, and isometric strength assessments at the back, elbow, or knee are associated with MSK-I risk; and (d) limited evidence that poor performance in a pull-up test and isotonic assessments of muscular strength are associated with MSK-I. Several measures of ME/MS are moderately or strongly associated with risk of MSK-I, but additional research is needed to identify and recommend specific assessments of ME/MS that predict MSK-I in both men and women. Future studies should also consider measures of ME and MS as a function of upper body, lower body, and core strength, and their potential association with specific, rather than general, MSK-I.

Weakley, JJS, Till, K, Read, DB, Phibbs, PJ, Roe, G, Darrall-Jones, J, and Jones, BL. The effects of superset configuration on kinetic, kinematic, and perceived exertion in the barbell bench press. J Strength Cond Res 34(1): 65–72, 2020—Training that is efficient and effective is of great importance to an athlete. One method of improving efficiency is by incorporating supersets into resistance training routines. However, the structuring of supersets is still unexplored. Therefore, the purpose of this study was to assess the effects of agonist-antagonist (A-A), alternate peripheral (A-P), and similar biomechanical (SB) superset configurations on rate of perceived exertion (RPE), kinetic and kinematic changes during the bench press. Ten subjects performed resistance training protocols in a randomized-crossover design, with magnitude-based inferences assessing changes/differences within and between protocols. Changes in rate of perceived exertion were very likely and almost certainly greater in the A-P and SB protocols when compared with the A-A, whereas all superset protocols had very likely to almost certain reductions in mean velocity and power from baseline. Reductions in mean velocity and power were almost certainly greater in the SB protocol, with differences between the A-A and A-P protocols being unclear. Decreases in peak force were likely and almost certain in the A-A and SB protocols respectively, with changes in A-P being unclear. Differences between these protocols showed likely greater decreases in SB peak forces when compared to A-A, with all other superset comparisons being unclear. This study demonstrates the importance of exercise selection when incorporating supersets into a training routine. It is suggested that the practitioner uses A-A supersets when aiming to improve training efficiency and minimize reductions in kinetic and kinematic output of the agonist musculature while completing the barbell bench press.

Bunn, JA, Ryan, GA, Button, GR, and, and Zhang, S. Evaluation of strength and conditioning measures with game success in Division I collegiate volleyball: A retrospective study. J Strength Cond Res 34(1): 183–191, 2020—The purpose of this study was to retrospectively assess relationships between strength and conditioning (SC) measures and game performance in Division I volleyball. Five years of SC and game data were collected from 1 women's Division I collegiate team, n = 76. Strength and conditioning measures included T-drill, 18.3 m sprint, back squat, hang clean, vertical jump, and broad jump. All game and SC stats were normalized to Z-scores. Analyses included assessing SC differences by position and multiple stepwise regression to assess relationships between game and SC stats. There was a significant difference by position for broad jump (p = 0.002), 18.3 m sprint (p = 0.036), vertical (p ≤ 0.001), and total strength (p = 0.019). Overall, game performance and SC measures were significantly correlated (r = 0.439, p ≤ 0.001). Multiple regression analyses indicated significant relationships (p ≤ 0.05) between SC measures and game success by position as follows: defensive specialist stats with squat and total strength; setters game stats with hang cleans, T-drill, and broad jump; pin hitter game stats with vertical, squat, and total strength; middle blockers game stats with broad jump. These data indicate that SC measures correlate well with game performance and are specific by position. These data could help SC coaches create a more precise training approach to focus on improving specific measures by position, which could then translate to improved game performance. These data could also help coaches with talent identification to determine playing time and rotations to maximize player ability and achieve success.
The Many Lives of Chief Kisco
Authors: Kearin Madeline Bourque
Published: August 2017

This paper deconstructs the folklore surrounding an early twentieth-century zinc figure of an American Indian that stands in the center of the village of Mount Kisco, New York. The identity that “Chief Kisco” has assumed over the past hundred years elides the nature of the origins of the statue, which was intended not as a statement of communal identity, but rather as the exact opposite. As a ready-made art object, the statue was emblematic of a new network of commodified goods that transformed the cultural geography of the United States; as it was utilized in Mount Kisco, the statue was a piece of temperance propaganda with strong nativist undertones that tapped directly into the class, religious, and ethnic divisions running through the turn-of-the-century village.

The mechanisms of vascular alterations resulting from early thyroid hormones deficiency are poorly understood. We tested the hypothesis that antenatal/early postnatal hypothyroidism would alter the activity of endothelial NO pathway and Rho-kinase pathway, which are specific for developing vasculature. Dams were treated with propylthiouracil (PTU, 7 ppm) in drinking water during gestation and 2 weeks after delivery, and their progeny had normal body weight but markedly reduced blood levels of thyroid hormones (ELISA). Small arteries from 2-week-old male pups were studied using wire myography, qPCR and Western blotting. Mesenteric arteries of PTU pups, compared to controls, demonstrated smaller maximum response to α1-adrenergic agonist methoxamine and reduced mRNA contents of smooth muscle differentiation markers α-actin and SERCA2A. Inhibition of basal NO synthesis by l-NNA led to tonic contraction of mesenteric arteries and augmented their contractile responses to methoxamine; both l-NNA effects were impaired in PTU pups. PTU pups demonstrated lower blood level of NO metabolites compared to control group (Griess reaction). Rho-kinase inhibitor Y27632 strongly reduced mesenteric arteries responses to methoxamine in PTU pups, that was accompanied by elevated Rho-kinase content in their arteries in comparison to control ones. Unlike mesenteric, saphenous arteries of PTU pups, compared to controls, had no changes in α-actin and SERCA2A contents and in responses to l-NNA and Y27632. In conclusion, thyroid hormones deficiency suppresses the anticontractile effect of NO and potentiates the procontractile Rho-kinase effects in mesenteric arteries of 2-week-old pups. Such alterations disturb perinatal cardiovascular homeostasis and might lead to cardiovascular pathologies in adulthood.
Multiple limit cycles in a Leslie–Gower-type predator–prey model considering weak Allee effect on prey
Authors: González-Olivares Eduardo , Rojas-Palma Alejandro , González-Yañez Betsabé
Published: August 2017

In this work, a modified Leslie–Gower-type predator–prey model is analyzed, considering now that the prey population is affected by a weak Allee effect, complementing results obtained in previous papers in which the consequences of strong Allee effect for the same model were established.In order to simplify the calculations, a diffeomorphism is constructed to obtain a topological equivalent system for which we establish the boundedness of solutions, the nature of equilibrium points, the existence of a separatrix curve dividing the behavior of trajectories. Also, the existence of two concentric limit cycles surrounding a unique positive equilibrium point (generalized Hopf or Bautin bifurcation) is shown.Although the equilibrium point associated to the weak Allee effect lies in the second quadrant, the model has a rich dynamics due to this phenomenon, such as it happens when a strong Allee effect is considered in prey population.The model here analyzed has some similar behaviors with the model considering strong Allee effect, having both two limit cycles; nevertheless, they differ in the amount of positive equilibrium points and the existence in our model of a non-infinitesimal limit cycle, which exists when the positive equilibrium is a repeller node. The main results obtained are reinforced by means of some numerical simulations.

Published: August 2017

A 3-day-old term, male infant presented to the emergency department for evaluation of bloody stools. The infant was born after an uncomplicated pregnancy followed by a normal spontaneous vaginal delivery. The mother was group B Streptococcus colonized, and received antenatal penicillin prophylaxis. The infant received routine delivery room care, and was given ophthalmic erythromycin and intramuscular vitamin K. Circumcision was performed without bleeding and he was discharged from the newborn nursery and the hospital after 48 hours. On the day of presentation, he had streaky bright red blood in 4 consecutive stools. After discussion with the infant’s pediatrician, the parents took him to the emergency department. The infant was afebrile, nursing well without emesis, and had made ∼10 wet diapers that day. The physical examination revealed a fussy infant with mild tachycardia, tachypnea, and scleral icterus. The complete blood count was unremarkable. Serum total bilirubin was 11.9 mg/dL, sodium 156 mmol/L, chloride 120 mmol/L, potassium 4.7 mmol/L, and bicarbonate 16 mmol/L. International normalized ratio was prolonged at 2.7, prothrombin time 26.6 seconds, partial thromboplastin time 38.9 seconds. The stool was hemeoccult positive. An obstructive radiograph series of the abdomen showed a nonobstructed gas pattern. Official radiology interpretation the following day reported possible pneumatosis intestinalis in the left and right colon. Our multidisciplinary panel will discuss the assessment of bloody stools in the term newborn, evaluation of electrolyte abnormalities, the diagnosis, and patient management.

Published: August 2017

The aim of this study was to estimate the intake of dry matter forage (CMSf) by grazing holstein cows. The research was conducted in northern Antioquia highlands; a silvopastoral system with Tithonia diversifolia and Cenchrsus clandestinum (SSP) and a monoculture C. clandestinum were used. Were estimated the CMSf by different methodologies and kikuyu:wild sunflower consumption relation, also the interchangeability of two methodologies was determined. There were two conducted trials, in the first trail SSP was used without browsing of wild sun ower and monoculture; in the second trial the same system was applied, with the difference that for the SSP animals browsed the shrubby by themselves. Twelve random infant holstein cows were used in the two systems. CMSf was estimated by indicators (I), agronomic (A) and grazing behavior (C) methods, method I was the reference. In trial I more CMSf was observed in the SSP, with an average of 14.7 kg/day (p<0.05); trial II showed no difference in the CMSf, with an average of 13.3 kg/day (p>0.005). The kikuyu:wild sunflower consumption relation was 95:5. The correlation coefficient of concordance between the methods I and C near to 0 shown that they are not interchangeable. The results suggest that the SSP evaluated supplied sufficient forage to ensure optimal CMSf.

The objective of this work was to evaluate the dynamic of corn and bean production in Mexico. Retrospective analysis was conducted in order to identify critic points, changes and adjustments given in the sector, as a result of Mexican government policies. Data was obtained from SAGARPA, Bank of Mexico, Secretary of Economy and Food and Agriculture Organization. Indicators were evaluated, as annual average growth rate (TCMA) and growing indicators, trends and real prices were evaluated. When doing the analysis, it was considered as a variable the country as a whole. The data of plantings, production, prices and imports of corn and beans in Mexico between 1980 and 2014 was analyzed. The plantings of corn and beans showed a decrease of 1.8 million and 193 thousand hectares respectively, the performance of corn increased on 1.47 t/ha and for beans, and 160 kg/ha for corn production and had a TCMA of 1.8% equivalent to 10.1 million tons, and beans had a TCMA of 0.89% with an increase of 338 783 t. Corn and beans, at constant prices, had a decrease of 64.6% and 59.0%, the decreased was of 441.9 and 976.3 dollars per ton respectively. The imports of corn had a TCMA of 2.84% ending 2012 with 9.5 million tons, the imports of beans don’t show any trend. The critic point of imports began with the North American Free Trade Agreement, where Mexico changed from a close economy to an open one, in which the government stimulates more imports, than national production.
Shear strength modelling of deep beam reinforced with high-strength steel without stirrups

Published: August 2017

Non-linear finite-element analyses were performed to model the shear behaviour of deep beams with high-strength reinforcement and grade-60 conventional reinforcement, without stirrups. The FE model was compared with experimental results from recent tests of deep concrete beams reinforced with both types of reinforcement and loaded until failure. A detailed comparative study of the FE and experimental results is presented, which demonstrates the capability of the analytical model to describe the observed experimental behaviour. The shear behaviour of beams reinforced with high-strength steel (HSS) was compared with that of beams reinforced with grade-60 steel to demonstrate the benefits of using high-strength reinforcement. The shear design provisions of current codes and mechanics-based models were also compared with the results from the analytical model. The findings of the study showed that diagonal shear cracking strength is independent of the type of reinforcement, while beams reinforced with HSS exhibited higher post-cracking shear strength than beams with conventional reinforcement. Strut-and-tie modelling is recommended for the design of deep beams reinforced with HSS since this method accounts for high strains in reinforcement and accounts for large-size effects. The current code provisions are suitable for slender beams regardless of type of reinforcement.

Infiltration by IgG-positive plasma cells is a common finding in tubulointerstitial nephritis. Indeed, it has been thought that CD138-positive mature plasma cells secrete mainly IgG, and the occurrence of tubulointerstitial nephritis with CD138-positive plasma cells secreting IgM has rarely been reported. Routine immunofluorescence of fresh frozen sections is considered the gold standard for detection of immune deposits. However, the immunoenzyme method with formalin-fixed, paraffin-embedded sections is superior for detecting IgM- or IgG-positive cells within the renal interstitium, thus histologic variants may often go undetected. We recently discovered a case of tubulointerstitial nephritis showing IgM-positive plasma cell accumulation within the interstitium. To further explore the morphologic and clinical features of such cases, we performed a nationwide search for patients with biopsy-proven tubulointerstitial nephritis and high serum IgM levels. We identified 13 patients with tubulointerstitial nephritis and IgM-positive plasma cell infiltration confirmed with the immunoenzyme method. The clinical findings for these patients included a high prevalence of distal renal tubular acidosis (100%), Fanconi syndrome (92%), and anti-mitochondrial antibodies (82%). The pathologic findings were interstitial nephritis with diffusely distributed CD3-positive T lymphocytes and colocalized IgM-positive plasma cells, as well as tubulitis with CD3-positive T lymphocytes in the proximal tubules and collecting ducts. Additionally, levels of H+-ATPase, H+, K+-ATPase, and the HCO3
−-Cl− anion exchanger were markedly decreased in the collecting ducts. We propose to designate this group of cases, which have a common histologic and clinical form, as IgM-positive plasma cell–tubulointerstitial nephritis.

A redução da maioridade penal no Brasil é um tema polêmico. Com intenção da redução, foram desenvolvidas diferentes propostas de emenda à constituição (PECs). Sendo um tema de importância a todos os cidadãos, é relevante avaliar as opiniões da população sobre o assunto. Este trabalho de pesquisa procurou fazer uma análise da percepção de alunos do ensino médio e professores sobre a redução da maioridade penal no Brasil. A amostragem contou com 90 alunos, sendo 30 do 1° ano do ensino médio, 30 do 2° ano e 30 do 3° ano, além de 15 professores. Os entrevistados responderam a um questionário contendo 21 questões de múltipla escolha relativas ao tema estudado. Dentre eles, 71% nunca foram vítimas de adolescentes em conflito com a lei e apenas 19% acreditam que a maioria dos crimes cometidos por menores são hediondos. É interessante notar que praticamente todos os alunos sabem que a partir de 16 anos podem votar; no entanto apenas 17% o fizeram. A maioria dos professores (75%) acredita na redução da maioridade penal, enquanto que os alunos ficaram bem divididos. Quase 80% do total de entrevistados acredita que crianças e adolescentes cometem crimes devido à impunidade. Apesar do baixo conhecimento sobre as medidas socioeducativas, a maioria dos alunos (62%) acredita que o aumento no tempo de cumprimento da medida socioeducativaseria melhor que a redução da maioridade penal, fato que convence apenas aproximadamente 33% dos professores.

Background: It was a randomized controlled prospective study. A large number of women in their advanced pregnancies often need labour induction for various reasons. This study aims to evaluate a safe, effective and inexpensive mode of medical induction. The purpose of the study is to evaluate the safety and efficacy of vaginal misoprostol versus oral misoprostol in induction of labour when used in equal doses.Methods: Two hundred patients were included in the study. They were divided into two groups of 100 patients each. One group i.e. Group A received vaginal misoprostol while the other group i.e. Group B received oral misoprostol. The dosage was 50μg every 6th hourly maximum of four doses. The progress of labour in both groups was charted on a partogram. The outcome of pregnancy, maternal and foetal outcomes were statistically analysed.Results: When compared with respect to age, height, gestational age, indication for induction, there was no difference in either of the groups. The numbers of doses of misoprostol for successful outcome of labour in the vaginal group i.e. 2.25±0.53 was lesser than the dosage needed in the oral group i.e. 2.71±0.60 (P value M 0.0001). which is highly significant. The induction-delivery interval was also less in the vaginal group compared to the oral group. (12.90±2.40 hours versus 15±75 hours). Only 13 women in the vaginal group needed acceleration with oxytocin in contrast to 17 women in the oral group. The need for caesarean section in women induced with vaginal misoprostol was 12 women in comparison to oral group which was 32 women. No statistically significant difference was seen in neonatal outcome in either of the groups.Conclusions: When given in equal doses the vaginal administration of misoprostol is more effective in successful induction of labour when compared to oral misoprostol.
Análise da influência do traço nas propriedades do compósito cimento-madeira

Os compósitos de cimento com adição de madeira apresentam vantagens, quando comparados a outros materiais convencionais da construção civil, como resistência à água, ao fogo e aos agentes deterioradores. Um dos obstáculos para o uso desse compósito é a inibição causada pela madeira na cura do cimento, devido aos componentes da madeira afetarem as reações, tendo como consequência um compósito de baixa qualidade. Dessa forma, este trabalho teve por objetivo avaliar diferentes traços do compósito cimento-madeira, utilizando resíduos de Pinus spp., por meio de ensaios de laboratório. Foi utilizado o cimento Portland CP II Z 32, relação água/cimento igual a 0,4; o aditivo químico escolhido foi o cloreto de cálcio para acelerar a pega. Para a comparação de desempenho, foram delimitadas quatro dosagens diferentes, com teores de adição de madeira de 10%, 20%, 25% e 33% em relação à massa de cimento. Para a análise, foram feitos ensaios das propriedades físicas e mecânicas para todas as dosagens, sendo, posteriormente, submetidas à análise da variância e teste de Tukey. Os resultados dos ensaios das propriedades físicas e mecânicas dos compósitos demonstraram que, para as relações escolhidas, quanto menor for a adição de madeira melhores serão os resultados das propriedades, mas mesmo os traços com maiores teores de madeira apresentam resultados relevantes, atentando-se apenas para o fato da relação água/cimento ser baixa para os casos analisados, e, devido a isso, ter influenciado negativamente nos resultados.

A produção dos mariscos na região metropolitana de João Pessoa – PB é comercializada nas feiras livres e na orla marítima para atender bares, restaurantes e demais consumidores. Os mariscos são processados de forma artesanal e sem os devidos cuidados recomendados pelas Boas Práticas de Fabricação (BPF), seja pela falta de estrutura física adequada, carência de utensílios apropriados ou de conhecimento em segurança alimentar. O processo de beneficiamento dos mariscos pode ser melhorado com a utilização de equipamentos térmicos para abertura e cocção e máquinas rotativas para separação da carne. Com base nos procedimentos realizados, no banho-maria, cozimento úmido, os mariscos apresentaram uma abertura total em 20 minutos (Temperatura 90 °C). Na autoclave, a pressão de 0.21 MPa (Temperatura 122 °C) e ciclo de 16 minutos resultaram em sua abertura total. A eficiência de retirada da carne do marisco, tanto no banho-maria quanto na autoclave, obteve uma média inferior a 10,0%. A máquina de separação da carne do marisco, com peneira rotativa, acionada pelo esforço humano via manivela, diminuiu o esforço físico e trouxe rapidez na operação. A máquina rotativa foi construída usando materiais alternativos e recicláveis. Os ensaios experimentais para determinação de sua eficiência, com carga variável de mariscos cozidos e abertos submetida previamente em autoclave, mostraram que o sistema proposto separou a carne do marisco de suas conchas, diminuindo os riscos de contaminação e garantindo a segurança alimentar.

El objetivo de este artículo consiste en analizar las normas y estrategias implementadas en el país para la formación de profesores en el uso de las tic. La metodología se ciñe a la investigación cualitativa de carácter documental; para ello, se revisaron y sistematizaron documentos sobre lineamientos de políticas de formación docente para el uso de las tic en el ámbito internacional y nacional y, asimismo, las estrategias de formación en tic. Los resultados señalan que los lineamientos de políticas sobre formación en tic tienen tres ejes importantes: acceso a las tic, formación de profesores y configuración de redes. El propósito de la formación en tic es obtener competitividad, calidad y equidad de la educación. Las estrategias de formación de profesores se han realizado por niveles y privilegiado la técnica de cascada. Las conclusiones destacan que varias de las estrategias de formación implementadas aún no superan la formación instrumentalista de las tic y no han logrado ahondar en la fundamentación pedagógica, comunicativa e investigativa, tal como se plantea en la normatividad. Por consiguiente, se requiere fundamentar el empleo de las tic desde la visión crítica y la perspectiva de mediación cultural.
La educación a distancia como respuesta a las necesidades educativas del siglo XXI
Authors: Chaves Torres Anívar Néstor
Published: August 2017

El desarrollo tecnológico, especialmente en el área de la información y la comunicación, ofrece a la sociedad herramientas útiles en diferentes campos, entre ellos el campo de la educación; por otra parte, la sociedad del conocimiento plantea nuevos retos a los sistemas educativos y a las personas que deben continuar su proceso de formación durante toda la vida. En este contexto, la educación a distancia se erige como una respuesta viable a la extensa demanda de educación, particularmente por personas que por diferentes circunstancias no pueden acceder a la educación presencial. No obstante, es poco lo que se conoce sobre esta modalidad y por ello surgen interrogantes que es preciso intentar responder, como: qué es la educación a distancia, cuál es su historia, en qué se diferencia de la educación presencial, cuáles son sus características, ventajas y limitaciones, a quien está dirigida y cuál es su nivel de reconocimiento y aceptación en la sociedad actual. Estos interrogantes motivaron la investigación bibliográfica cuyos resultados se presentan en este documento.
