Alimentos permitidos em um presídio feminino em Cajazeiras - classificação quanto ao grau de processamento

The Brazilian prison system is marked by precariousness, overcrowding of cells and poor conditions of structure, hygiene and food. Thus, this study aims to analyze which types of food are allowed to enter a female prison located in northeastern Brazil, second degree of processing. The study was conducted in a female prison located in the city of Cajazeiras, where data relating to age, years of study and the presence of chronic diseases of 33 convicted in a closed regime were collected. It was also performed the survey of food allowed to enter the prison, which were categorized according to the degree of processing, using the classification of the Brazilian Food Guide. The presence of 30 types of food in the list was verified. Although vegetables are listed as all allowed, most foods are processed and ultra-processed, especially the latter, which total 12 products, including sausages, soft drinks, noodles, juice powder, among others. This way, the list of food allowed to enter the prison is integrated by an excessive amount of processed and ultra-processed food, which can put the apenadas in risk to health.
Calculation of Morse Potential Parameters of bcc Crystals and Application to Anharmonic Interatomic Effective Potential, Local Force Constant

In this work, Morse potential parameters of bcc crystals have been calculated based on the calculation of volume per atom and atomic number in each elementary cell, as well as the energy of sublimation, the compressibility and the lattice constant. They are used for studying the anharmonic interatomic effective potential, local force constant in XAFS (X-ray Absorption Fine Structure) theory. Numerical results for Fe, W and Mo are found to be in good agreement with experiment and with those of other theories.
Fully distributed consensus for higher-order nonlinear multi-agent systems with unmatched disturbances

In this paper, the distributed consensus problem is investigated for a class of higher-order nonlinear multi-agent systems with unmatched disturbances. By the back-stepping technique, a new distributed protocol is designed to solve the consensus problem for multi-agent systems without using the information of the Laplacian matrix and Lipschitz constants. It is proved that the practical consensus of multi-agent systems with unmatched disturbances can be achieved by the proposed protocol. Finally, the validity of the proposed scheme is verified by a simulation.
Size effect in the titanium/diamond‐like carbon bilayer films: effect of relative thickness on their structure and mechanical properties

Titanium/diamond‐like carbon (Ti/DLC) bilayer films with different relative thickness were fabricated by direct‐current and pulsed cathode arc plasma method. Microstructure, morphological characteristics, and mechanical properties of the films were investigated in dependence of the thickness of Ti and DLC layers by Raman spectroscopy, atomic force microscopy, Knoop sclerometer, and surface profilometer. Raman spectra of Ti/DLC bilayers show the microstructure evolution (the size and ordering degree of sp2‐hybridized carbon clusters) with varying the thicknesses of Ti interlayer and DLC layer. Nano‐scaled Ti interlayer of 12–20 nm thickness presents the largest size effect. The catalytic effect of the sublayer is most pronounced in the carbon layer of less than 106 nm. In these thickness ranges, the bilayer films possessed the highest micro‐hardness and reactivity between atoms at interface. Internal stress in the bilayer monotonically decreases, with the thickness of Ti interlayer increasing to 30 nm and then becomes stable with the thickness. These results are associated with the occurrence of atomic diffusion process at Ti/C interface, and they are of cardinal significance to optimize the structure and mechanical properties of carbon‐based multilayer films.

The Effect of the OMT in Electromagnetic Simulations of MeerKAT Primary Beams

Until recently, full-wave electromagnetic (EM) primary beam simulation results for MeerKAT’s offset-Gregorian reflector antennas in $L$ -band (856–1711 MHz) differed systematically and inexplicably from high-precision field measurements. The measured beam patterns exhibit unexpected frequency- and polarization-dependent pointing offsets (squint) in both horizontal (H) and vertical (V) directions for the copolarization patterns, as well as distinctive asymmetries in the horizontal direction for the cross-polarization patterns in the upper half of the band. These effects were not predicted by design stage simulations that are based on the excitation of the fundamental waveguide mode only. Conventional large reflector simulation strategies used in the literature idealize the orthomode transducer (OMT) and waveguide and exclude this module from primary beam simulations entirely. This research shows that the inclusion of MeerKAT’s wide-bandwidth OMT and waveguide in the simulation is critical to the excitation of the TE21 mode, which results in the asymmetric features observed in the measurements. It is found that the characteristic frequency-dependent asymmetries of the primary beams are a consequence of the design of the OMT and cannot be attributed to manufacturing tolerances, reflector collimation errors, nor the coupling to conductive structures near the feed horn.
Production of Thermo-Alkali-Stable Xylanase from Bacillus licheniformis Isolated from Natural Hot Water Geyser

Context: Xylanase constitutes 20% of world enzyme market. Significantly, they are used in poultry feed, paper pulp, bakery, and textile industries. In view of the increasing demand of the enzyme, it is vital to develop indigenous strains and scalable technologies for the production of industrial enzymes. Aims: The objective of the present paper was to isolate a high-yielding strain of thermo-alkali-stable xylanase-producing bacteria for potential application in paper and pulp and biofuel industry. Methods: Sampling for prospecting of suitable organism was carried out from the places with dead and decaying lignocellulosic waste, and then Congo red screening was employed for the primary isolation of xylanase producers. Results: We report the isolation of 18 different strains of xylanase producer bacteria from natural hot water geyser of Sohna, Haryana, India. Subsequently, two of these isolates were chosen for further studies based on xylanase yield and desirable properties such as thermostability and alkali stability of xylanase produced. Conclusion: Isolate B2 was later identified as Bacillus licheniformis, whereas isolate Y3 was identified as Brevibacillus borstelensis. This strain when cultured at 35°C for 72 h showed xylanase production at 128 U/ml. The molecular weight of xylanase was determined to be 25 kDa. The production was scaled up in a 5-L stirred-tank bioreactor which led to high xylanase concentration of 380 U/ml in the first 48 h of culture.
Determination of Stable Isotopes, Minerals, and Volatile Organic Compounds in Romanian Orange Juice

ABSTRACT Twenty-three commercial orange juice varieties were characterized on the bases of isotopic, elemental, and volatile organic concentrations. One goal of this study was to evaluate the authenticity of the samples by the determination of exogenous water and sugar. Volatile organics and elemental profiles were determined to evaluate the nutritional quality of the juice. Results showed that all of the products were produced from concentrate by dilution with water and contained exogenous sugar. A new flavor index was proposed as the ratio of total sesquiterpenes to total terpenes without limonene to assess the quality of these juice samples.
A Study on Satisfaction of Elderly Care Service Quality Based on Different Groups: Taking the Monitoring Data of Liaoning Province as an Example

The monitoring and analysis of the social public service quality is conducive to promoting the construction of a service-oriented government that the people are satisfied with. In this paper, the third-party quality monitoring is carried out in 14 cities in Liaoning Province from 11 public service areas, including residential environment, public transportation, infrastructure, medical and health care, public security, cultural and sports, compulsory education, elderly care service, employment service, social security and administrative convenience. The results show that the public's satisfaction with social security, compulsory education, residential environment, public security and employment service is low, which needs to be paid attention to and further improved by Liaoning provincial government.
A Viral Disease That Damages the Immunity Conferred by Different Viral Diseases or Vaccination

In this paper we modify a standard SIR model used to study the spread of some diseases by incorporating a disease that destroys the immunity that is conferred by having one of the other diseases or being vaccinated against the disease. A specific biological example of this occurs with measles. Studies of recent measles’ patients has shown that many patients have lost some (or all) of their immunity to other diseases from which they were previously protected. In the future, models like those developed here might be helpful in understanding how viruses that affect multiple organ systems can impact the effect the disease has on at risk populations.

Some Integral Inequalities for 
 n
 -Polynomial 
 ζ
 -Preinvex Functions

In this paper, we study the properties of n -polynomial ζ -preinvex functions and establish some integral inequalities of Hermite-Hadamard type via this class of convex functions. Moreover, we discuss some special cases which provide a significant complement to the integral estimations of preinvex functions. Applications of the obtained results to the inequalities for special means are also considered.
Behavior of two-temperature model in intermediate hypersonic regime

Shock standoff distance for a sphere is calculated to examine the behavior of the existing two-temperature model in the intermediate hypersonic flow regime. Calculations are carried out for three binary scaling parameter values, corresponding to nearly frozen, nonequilibrium, and nearly equilibrium flows, respectively. The obtained shock standoff distances are compared with the experimental data obtained in a ballistic range. The two temperature model reproduces the shock standoff distances in the intermediate hypersonic flows fairly well but tends to lose its accuracy where vibrational excitation occurs but chemical reactions are nearly frozen
Advanced LVRT Control Scheme for Offshore Wind Power Plant

Offshore wind farms (OWF) are being rapidly integrated to the power systems, which can be primarily attributed to saturation of the mainland onshore area, and high wind speed in offshore sites. However, to maintain stable grid operation, OWFs are required to comply with Low Voltage Ride Through (LVRT) capability. OWF during LVRT period should not only stay grid connected, but also support the grid during the disturbance. In this paper, a new communication-independent LVRT control scheme for HVDC connected OWF has been proposed. Under the proposed strategy, OWFs not only successfully ride through a fault induced voltage dip, but also comply with active power recovery ramp rate during the fault recovery period. Besides complying with LVRT requirement and ramp rate limit, the proposed strategy improves voltage dip induced frequency (VDIF) issue by increasing active power injection from the OWF during LVRT period. The proposed LVRT strategy also exploits the stored energy in HVDC link capacitors in order to reduce the impact of VDIF issue. The proposed and the conventional LVRT strategies for HVDC connected OWF have been implemented and evaluated on IEEE 39 bus benchmark system.
Model Predictive Current Control With Low Complexity for Single-Phase Four-Level Hybrid-Clamped Converters

This article presents a simplified model predictive control (MPC) method for single-phase four-level hybrid-clamped converters (1P-4L-HCCs), achieving high-quality current control and strong capacitor voltage balancing. Different from a conventional MPC, the proposed method aims to dramatically reduce switching states (control voltage vectors) in the cost function optimization of MPC. It utilizes only 16 switching states, compared to 64 in conventional methods, resulting in reduced execution time and significantly increased control bandwidth. Steady-state and dynamic performances are evaluated by simulated and experimental test, and the main results are provided to verify the effectiveness of the proposed MPC method.
Enabling Dynamic Behaviors With Aerodynamic Drag in Lightweight Tails

Many agile legged animals employ lightweight, furry tails to regulate orientation during running, leaping, and turning. Most robots attempting the same tasks either lack a tail or employ one with high inertia, which can induce impractical payload and energy costs. Inspired by nature's solution to this tradeoff, we explore the use of aerodynamic drag tails in reorientation tasks. In this article, we present a model of the aerodynamic drag and from this derive a metric that allows for direct comparison between aerodynamic and inertial tails. Motivated by this model, we construct a tail to maximize this effectiveness while minimizing inertia. We demonstrate the utility of this tail for two dynamic behaviors executed on a quadrupedal robot. First, in aerial reorientation the robot achieves a 90$^{\circ }$ rotation within one body length of fall at the same performance as an inertial tail but with just 37% of the normalized inertia. Second, the forward acceleration of the robot is improved by 12% despite increasing the system mass by 10% over a tailless version. These results show that aerodynamic drag can provide significant control authority for a robot while decreasing the payload and energy cost.
Comparison of Tympanic and Tail Temperatures in Angus and Brahman Steers

In cattle, core body temperature can be used as an important indicator of heat stress level. However, accurately recording core body temperature can be difficult and labor intensive. The objectives of the current study were 1) to compare the recorded tympanic and tail body temperature measurements in steers and 2) to determine the body temperature change of Angus and Brahman steers in a hot and humid environment. Data was analyzed using a repeated measure model where repeated measures were hourly tympanic and tail temperatures and their difference for individual steers during the day of the experiment. There was a significant breed effect (P=0.01), hour (P<0.0001) and breed by hour interaction (P<0.0001) for the tympanic temperature. Brahman steers, which are known to have superior thermotolerance, maintained a lower body temperature than the Angus steers during the afternoon under grazing conditions. In the Brahman steers there was only a minimal increase in the body temperature throughout the day, an evidence of the thermotolerance ability of the breed. In the Angus steers, which experienced an increase in their body temperature from hour to hour with a peak around 1600 hour; there was a significant difference between the tympanic and tail temperature during the times when the body temperature as measured by the tympanic recordings was the highest (1300 to 1700 hour). Our results indicate that the tympanic temperature can be used to accurately and continuously monitor core body temperature in a natural environment for up to several days and without disturbing the animal.
Coupling Effects of Controlled-release Urea and Water on Tomato Yield and Soil Nitrate Under Reduced Irrigation

In greenhouse tomato production, excessive applications of nitrogen and water have aroused increasing concerns over food safety and groundwater quality. An experiment was conducted in greenhouse to investigate how controlled-release urea at two rates coupled with two levels of irrigation influenced tomato growth, yield and quality as well as soil nitrate contents. The results showed that there was no significant difference in leaf chlorophyll content, stem diameter and fruit width among treatments. Compared with the routine nitrogen application, applying controlled-release urea at normal amount(600 kg N·hm-2)increased single fruit weight, yield, soluble sugar content, sugar to acid ratio and Lycopene by 8.05%~36.1%, 9.02%~36.1%, 15.3%~27.2%, 24.0%~24.4% and 26.4%~81.9%, respectively, but decreased fruit nitrate contents by 5.80%~8.41% and soil nitrate by 20.5%~70.2%. Reducing N supply by 33%(to 400 kg N·hm-2)decreased tomato yield by 17.2%(P0.05)at 800 m3·hm-2of irrigation level(51% of the normal irrigation level). At the two rates of controlled-release urea, reducing irrigation level from 1000 m3·hm-2to 800 m3·hm-2improved tomato lycopene content by 18.2% ~40.6%(P 0.05)and reduced tomato nitrate content by 10.1%~10.9%. However, irrigation at 800 m3·hm-2lead to a reduction(10.1%)of Vc content in tomato at 400 kg N·hm-2of controlled-release urea. It is recommended that controlled-release urea at 600 kg N·hm-2with 800 m3·hm-2or 1000 m3·hm-2irrigation or at 400 kg N·hm-2with 1000 m3·hm-2irrigation could all be used for tomato production. Future research is necessary on effectively reducing soil nitrate.
A Step towards Sustainable Self-Compacting Concrete by Using Partial Substitution of Wheat Straw Ash and Bentonite Clay Instead of Cement

Self-compacting concrete (SCC) is a special type of concrete that is highly flowable, nonsegregating and spread into place by its own weight, completely filling the formwork even in the presence of dense reinforcement and then encapsulating the rebar without the need for any additional compaction. This research was carried out to evaluate the effects of bentonite clay and wheat straw ash as a partial substitution for cement in SSC. Bentonite clay and wheat straw ash were added in proportion of 0%, 5.0%, 10%, 15%, and 20% of the weight of the cement. Fresh characteristics were evaluated based on its passing ability and flowability using slump flow, slump T50, L-box, and V-funnel tests. After 7 days, 14 days, and 28 days of curing, cylinders of standard size were cast and tested for compressive and split tensile strength. The test results indicate that bentonite clay and wheat straw ash decrease the passing ability and filling ability of SCC. Furthermore, the concrete specimens’ tests indicate that wheat straw ash and bentonite clay additions of up to 10% and 15% of the weight of the cement tend to improve the compressive and split tensile strength of hardened SCC. Response surface methodology (statistical models) is used to optimize the combined dosage of wheat straw ash and bentonite clay and is verified through experimental tests. It can also be suggested that bentonite and wheat straw ash are successfully neutralized in concrete instead of cement.
Fast copula variational inference

ABSTRACT Mean-field variational inference, built on fully factorisations, can be efficiently solved; however, it ignores the dependencies between latent variables, resulting in lower performance. To address this, the copula variational inference (CVI) method is proposed by using the well-established copulas to effectively capture posterior dependencies, leading to better approximations. However, it suffers from a computational issue, where the optimisation for big models with massive latent variables is quite time-consuming. This is mainly caused by the expensive sampling when forming noisy Monte Carlo gradients in CVI. For CVI speedup, in this paper we propose a novel fast CVI (abbr. FCVI). In FCVI, we derive the gradient of CVI objective by an expectation of the mean-field factorisation. Therefore, we can achieve a much efficient sampling from the -dimensional mean-field factorisation, enabling to reduce the sampling complexity from to . To evaluate FCVI, we compare it against baseline methods on modelling performance and runtime. Experimental results demonstrate that FCVI is on a par with CVI, but runs much faster.
Microbial communities of wild-captured Kemp’s ridley (Lepidochelys kempii) and green sea turtles (Chelonia mydas)

Conservation efforts for endangered sea turtle species, such as Kemp’s ridley turtles Lepidochelys kempii and green turtles Chelonia mydas, may benefit from information on the microbial communities that contribute to host health. Previous studies examining host-associated microbiomes of these species have been limited in geographic region, life stage, and/or health. Here, we characterized the microbiome of the oral cavity and cloaca from wild-captured Kemp’s ridley and green turtles off the west coast of Florida, USA, by using Illumina sequencing to analyze the 16S rRNA gene. Microbial communities were distinct between body sites as well as between turtle species, suggesting that the turtle species is more important than the local environment in determining the microbiome of sea turtles. We identified the core microbiome for each species at each body site and determined that there were very few bacteria shared among the oral samples of both species, and no taxa co-occurred in the cloaca samples among both species. The core microbiome of the green turtle cloaca was primarily from the order Clostridiales, which plays an important role in digestion for other herbivorous species. Due to high prevalence of fibropapillomatosis in the green turtles (90%), we also investigated the correlation between the microbiome and the severity of fibropapillomatosis, and we identified changes in beta diversity associated with the total number of tumors. This study provides the first glimpse of the microbiome in 2 sympatric species of sea turtle and sheds an important species-specific light on the microbiome of these endangered species.
