Determination of pH and water holding capacity of beef from selected butcher shops of Mekelle, Ethiopia

A cross-sectional study was undertaken to determine the water holding capacity (WHC) of beef sold in selected butcher shops of Mekelle, Ethiopia and to establish the effects of pre-slaughter rests and age of the animals with pH and WHC of the meats. A total of 80 samples from 80 randomly selected butcher shops were sampled in 6 months study period of time, from May to October. Each sample was accompanied by questionnaires. The meats were taken to the laboratory to measure pH and water holding capacity using the filter paper press and drip loss methods. The means and standard deviations of filter paper press and drip loss were found as 49.4 ± 5.85 and 4.58 ± 0.96, respectively. The age of the slaughtered animals had significant association (p<0.05) with the pH measured at 24 h post-slaughter, drip loss and filter paper press measurements. The pre-slaughter rest period had strong effect on pH (p<0.05) at 3 h post-slaughter. The present study concluded that water holding capacity and pH as quality indicators of meat are influenced by age and pre-slaughter rest of the slaughtered animals. Key words: Age, drip loss, filter paper press, pH, pre-slaughter stress.
Design and Fabrication of Low Phase Noise Oscillator Using $Q$ Enhancement of the SISL Cavity Resonator

In this article, an X-band low phase noise oscillator using a high-quality (<inline-formula> <tex-math notation="LaTeX">$Q$ </tex-math></inline-formula>) cavity resonator based on the substrate integrated suspended line (SISL) technology is proposed. To achieve a low phase noise, the partly dielectric substrate cutting off and double-metal structure are used to improve <inline-formula> <tex-math notation="LaTeX">$Q$ </tex-math></inline-formula> of the resonator. The principles of the proposed <inline-formula> <tex-math notation="LaTeX">$Q$ </tex-math></inline-formula>-enhancement techniques are analyzed theoretically and verified experimentally. Using the proposed techniques along with the electromagnetic shielding property of the SISL technology, the designed cavity resonator can achieve a high loaded <inline-formula> <tex-math notation="LaTeX">$Q$ </tex-math></inline-formula> up to 792. The measurement results indicate that the oscillator using the proposed high-<inline-formula> <tex-math notation="LaTeX">$Q$ </tex-math></inline-formula> resonator features a low phase noise of −133.91 dBc/Hz at 1-MHz offset from a carrier frequency of 11.87 GHz. In addition to the low phase noise property, the proposed oscillator has the merits of low cost, high integration, and self-packaging.
Stabilizing uncertain steady states of some dynamical systems by means of proportional feedback

Abstract. A simple zero-order proportional feedback technique for stabilizing unknown fixed points is described. The technique employs either artificially created or natural stable fixed point to find the coordinates of the unknown unstable fixed point. Four physical examples have been investigated, namely the mechanical pendulum, the autonomous Duffing damped oscillator, the van der Pol oscillator, and the Lorenz system have been considered both analytically and numerically.
Forecasting Latin-American Currency Exchange using Models with Static and Stochastic Volatility

Context: The currency market is known as the most liquid market in the financial system. Its strong repercussion in the economy is tied to the capitalization and the impulse that this market offers through the increase of investments and therefore of macroeconomic effects that is found in the development of the economy, For these reasons, it is relevant to study models that predict the behavior of the main Latin currencies.Method: Two models are proposed for the prognosis and the identification of factors implicit in the behavior of these currencies. The first proposed model corresponds to the Black-Scholes, which allows obtaining the future price of the currency based on integrating price processes, a Wiener process and a static volatility is recognized. The second model is Heston, which describes the evolution of the volatility of an underlying asset and assumes a stochastic volatility.Results: After the application of the proposed mmodels, their efficiency are evaluated by means of the Diebold-Mariano Test, in order to identify the forecast model that best adapts models, their efficiency are to the real behavior of the parities.Conclusions: It is identified that the Heston model offers a better fit to the forecast, assuming random volatility in the short term for each of the currencies, while the long term presents the largest adjustment of the Black & Scholes model, It is evident that the longer the forecast time, the greater the uncertainty and the greater the prediction error.

Continuously Adjustable Capacitor for Multiple-Pickup Wireless Power Transfer Under Single-Power-Induced Energy Field

This article proposes and implements a continuously adjustable capacitor for multiple-pickup wireless power transfer (WPT), aiming to enhance the energy security performance under single-power-induced energy field. With the accelerated development and commercialization of WPT, the energy security issue shows the increasing significance for multiple-pickup WPT systems, where the induced open radial electromagnetic field facilitates all involved pickup coils to access the wirelessly transferred energy. If utilizing no appropriate protection strategy, the energy privacy is inevitably jeopardized, especially for the single-power-induced energy field where the auxiliary technique, such as the radio-frequency identification, cannot identify the multiple pickups. Accordingly, this article proposes a continuously adjustable capacitor that enhances the security/transmission performance for multiple-pickup WPT systems. Differing from impedance adjusting schemes reported in previous studies, the continuously adjustable capacitor can continuously adjust the impedance to match the encrypted switching frequency dynamically and continuously. In such ways, it can effectively enhance the flexibility of the WPT hardware platform for the cryptographic algorithm, thus significantly reduce the possibility of power being hacked. Finally, the simulated and experimental results are provided to verify the feasibility of the proposed continuously adjustable capacitor for the energy encryption of multiple-pickup WPT systems.

Design of a compact dual-band MIMO antenna with high isolation for WLAN and X-band satellite by using orthogonal polarization

ABSTRACT This paper presents a new design of a compact dual-band Multiple Input Multiple Output (MIMO) antenna with high isolation for WLAN and X-band satellite applications. The proposed antenna is realized using three slots: the first slot is used on the upper layer to create the second resonance frequency at 5.3 GHz and two symmetrical slots are etched on the bottom layer to enhance the impedance bandwidth of the two operating bands. In order to obtain a low mutual coupling, the two antenna elements have an orthogonal polarization. The simulated results show that the MIMO antenna has a high isolation (S21 ≤−22.5 dB) at the two desired bands with impedance bandwidths are about 4.15% (5.19–5.41 GHz) and 4.81% (7.30–7.66 GHz). In addition, the MIMO parameters like envelope correlation coefficient (ECC), diversity gain (DG), Total Active Reflection Coefficient (TARC), realized gain and efficiency are also analyzed.
Quimioterapia associada à terapia anti-retroviral de alta eficácia no tratamento dos linfomas não-Hodgkin agressivos relacionados à Síndrome da Imunodeficiência Adquirida Chemotherapy combined with highly active antiretroviral therapy for the treatment of aggressive AIDS related lymphomas

AbstractNon-Hodgkin lymphoma is one of the most frequent oncologicalcomplications in patients with the Acquired Immune-DeficiencySyndrome (AIDS). In other countries, after the introduction ofthe Highly Active Antiretroviral Therapy (HAART), the drop inthe incidence of systemic aggressive lymphomas was belowexpectations, although the survival of these patients rose. InBrazil, little is known about the clinical behavior and survival ofthe patients with lymphoma and AIDS in the post-HAART era.The aim of this study was to retrospectively evaluate 25 patientswith lymphomas and AIDS, treated with the combination ofchemotherapy and HAART. In agreement with the literature mostof the patients were male (20 patients - 80%) with a median ageof 39 years. We observed a predominance of the Diffuse Large BCell Lymphoma subtype (13 patients - 52%), advanced stage(15 patients - 60%), with extra-nodal disease (22 patients - 88%)and B symptoms (18 patients - 72%). Previous AIDS diagnosiswas present in 14 patients (56%), higher than that reported inother series. Fifty-two percent achieved CR, the estimatedprobability of overall survival and disease-free survival at 3years were 54% e 42%, r espectively. The median overall survivaltime was 15 months. Hematological toxicity and infections werefrequently observed, but no toxicity-related deaths were seen.Therefore we conclude that the combined chemotherapy-HAARTtreatment is feasible in Brazilian patients and can provide simi-lar overall survival than that described for some internationalgroups, with an acceptable toxicity profile.

A Computational Approach for the Understanding of Stochastic Resonance Phenomena in the Human Auditory System

Stochastic resonance (SR) is a nonlinear phenomenon by which the introduction of noise in a system causes a counterintuitive increase in levels of detection performance of a signal. SR has been extensively studied in different physical and biological systems, including the human auditory system (HAS), where a positive role for noise has been recognized both at the level of peripheral auditory system (PAS) and central nervous system (CNS). This dualism regarding the mechanistic underpinnings of the RS phenomenon in the HAS is confirmed by discrepancies among different experimental studies and reflects on a disagreement about how this phenomenon can be exploited for the improvement of prosthesis and aids devoted to hypoacusic people. HAS is one of the human body’s most complex sensory system. On the other hand, SR involves system nonlinearities. Then, the characterization of SR in the HAS is very challenging and many efforts are being made to characterize this mechanism as a whole. Current computational modelling tools make possible to investigate the phenomena separately in the CNS and in the PAS, then simplifying the analysis of the involved mechanisms. In this work we present a computational model of PAS supporting SR, that shows improved detection of sounds when input noise is added. As preparatory step, we provided a test signal to the system, at the edge of the hearing threshold. As next step, we repeated the experiment adding background noise at different intensities. We found an increase of relative spike count in the frequency bands of the test signal when input noise is added, confirming that the maximum value is obtained under a specific range of added noise, whereas further increase in noise intensity only degrades signal detection or information content.
A Consideration on Image Composition of Defects and Background in Appearance Inspection of Plastic Products Based on Machine Learning

This paper describes a synthesis method for the images with defects used in training a Region-based Convolutional Neural Network (R-CNN) applied to an appearance inspection of plastic products. The proposed heuristic method is that, firstly, some typical defect patterns are cut from the actual images and then, these defect patterns are pasted to the background by changing the size, rotations, colors, or making them into black-and-white, etc. In the experiments, firstly, 81 defect patterns are cut in 50 actual images and 500 images are synthesized by applying the suggested method. Then, R-CNN is trained by using these 500 images and it is applied to the detection problem of 53 defective patterns in 20 images. As a result, the detection ratio and the hit ratio are 81% and 86%, respectively and it is likely that the suggested training method is promising for practical uses with some improvements.

Light-Field Camera for Fast Switching of Time-Sequential Two-Dimensional and Three-Dimensional Image Capturing at Video Rate

In this article, we propose a time-sequential switching light-field (LF) camera for an alternative image capture of the high-resolution two-dimensional (2-D) images and three-dimensional (3-D) LF elemental images as additional functionalities. For image data acquisitions of both the 2-D and 3-D LF imaging of moving objects at a video frame rate (or even higher frame rate up to approximately 1000 f/s), a polarization-dependent-switching microlens array (MLA) is implemented in the LF camera system instead of a conventional passive-type MLA. By controlling the incident polarization conditions using an electrically fast-switching liquid crystal layer, the imaging mode can be time-sequentially switched quite rapidly (switching times of approximately 220 and 290 μs for the mode conversions from the 3-D LF to the 2-D mode, and the reversal mode change, respectively). Using the elemental image sets sampled from the alternating time-sequential imaging results, either the directional-view images or depth-refocused images can be reconstructed and provided at a moving picture frame rate. The depth-refocused images are possible for a wide depth range from 25 to 350 cm. Directional views of 22 × 22 and 9 × 9 in portions can be reconstructed for the single-shot image capture and the time-sequential video-rate image capture, respectively.
Hybrid reinforcement design of longitudinal joints for segmental concrete linings

In mechanized tunneling, the performance of segmental tunnel lining segments is closely bound to the longitudinal joint design. The guiding local effect is partial area strip loading with predominantly plane load distribution. Current normative standards only inadequately cover this case, which leads to an underestimation of the actual bearing capacities and thus offers considerable optimization potential. A hybrid material concept is proposed to improve the joints' performance, which is based on the results of robust combined trusscontinuum topology optimization. It combines high‐performance steel fiber reinforced concrete in the area of load application with conventional materials used for the remaining regions. A relocation of the gasket to the segments' center proves to provide better protection, and a double hinge neck leads to a more efficient load transfer. The effects of these measures on the structural performance are analyzed experimentally and compared against conventional designs. The results show pronounced increases in bearing capacities by using hybrid reinforcements and provide a quantification of optimization based design modifications.
Integrated Components of Intercultural Competence in English Language Teaching at College: Case Study

In this global world, foreign language teaching has been demanded to be intercultural teaching which means that cultural teaching should be integrated in language teaching as well as language competence, in English language teaching for instance. On the ground that the importance of foreign language teaching and learning is largely for purpose of international communication, and intercultural knowledge has crucial role in successful communication. Therefore, this paper reports on a qualitative case study which investigates two English teachers’ practice of integrating intercultural competence in English language teaching at college level. Specifically, this paper provides analysis of intercultural components embedded in teachers’ practice of intercultural integration in teaching English. The data were collected through observation, and unstructured observational notes were employed. The observational data were analysed following sub-processes, are familiarizing, reducing, identifying and classifying, interpreting, and presenting. The result indicates that both English teachers’ understand the objective of English language teaching that teaching language is also teaching the culture as it is showed in their teaching process an intercultural integration, which includes some intercultural components such as attitudes, knowledge, and skills.
