Comparison of organic acids supplementation on the growth performance, intestinal characteristics and morphology, and cecal microflora in broilers fed corn-soybean meal diet

Objective The aim of this study was to compare the effects of three kinds of organic acid (OA) products on the growth performance, intestinal characteristics and morphology, and cecal microflora in broilers fed a corn–soybean meal meal diet. Methods A total of 420 one-day-old male Cobb 500 broilers with an average initial body weight of 49.11±1.02 g were used in this 42-day experiment. Birds were randomly allotted to one of five treatments (7 replicates with 12 birds per replicate). Treatments consisted of negative control (NC), basal diet; positive control (PC), basal diet+100 mg/kg of Aviramycin; OA1, basal diet+500 mg/kg of OA product 1; OA2, basal diet+1,000 mg/kg of OA product 2; and OA3, basal diet+1,200 mg/kg of OA product 3. Results The results indicated that OA product addition had no effect on growth performance parameters, such as body weight gain, feed intake, and feed conversion ratio, from days 1 to 14, 15 to 28, and 0 to 42, or on the pH values of the intestine, intestinal weight, or intestinal weight to body weight ratio. The intestinal morphology in terms of villus height and crypt depth were affected by dietary supplementation of OA products, respectively. Furthermore, dietary addition of OAs had positive influences on the maintenance of the cecal microflora based on the results of 16S rRNA analysis. Conclusion Dietary inclusion of three kinds of OA products all benefit broilers, but the mode of action may be different. This study provides a basis for the application of OA products used in the poultry industry.
Research on Big Data Management and Storage Based on Linux Container

These years, a new generation of virtualization technology, aka Linux container,is becoming more and more popular. Linux container is a lightweight virtualization technology which providing resource isolation with little performance overhead. This paper designs and implements a solution for Big Data management and storage based on Linux container. The main work and contributions of this paper are as follows: 1. Researched the next generation distributed resource scheduling technology. Normally, to integrating into existing distributed schedulers, distributed applications need to write a specific accessing module. We designed a new 2-layer distributed resource scheduler architecture which reduced the coupling between scheduler and distributed applications. 2. Researched the combination of Linux container with Big Data system. We brought Linux container into the Big Data system to replace traditional virtualization technology, thus improving the resource utilization of the underlying hardware. 3. Designed and implemented a prototype system and tested its flexibility, application performance overhead and scheduling overhead.
Design and analysis of a special digital signature scheme

In this work we analyze the BG14 digital signature, and show that its security-proof is incomplete in the sense that a necessary security check is missing in its sign algorithm. Moreover, we offer an alternative approach for the phase 2 security-proof of the BG14 scheme. These two contributions are summarized in our digital signature scheme Π.
The effects of protocadherin 8 and WWOX in prostate adenocarcinoma

Objective : The protocadherin 8 (PCDH8) gene, located on chromosome 13q14.3 encodes an integral membrane protein. WWOX (frag-ile site FRA16D oxido-reductase) is a tumor suppressor gene located in region 16q23.324. 1. The aim of this study was to investigate the staining pattern of protocadherin 8 and WWOX in adenomatous hyperplasia and prostate adenocarcinoma. Methods : Seventy adenomatous hyperplasia and 70 prostate adenocarcinoma preparations stored at the pathology department from 2013–2016 were retrospectively analyzed. Samples immunohistochemically stained with WWOX or protocadherin 8 were evaluated by two pathologists under a light microscope. After pathological investigation of the samples, the expression of WWOX and protocadherin 8 was scored. WWOX and PCDH8 expression was assessed semi-quantitatively according to staining intensity scored as none, mild, moderate, and strong (0 to 3+). For analysis of the data, the mild, moderate and strong staining scores were combined (as positive) and the data were classified as negative or positive. Differences in the WWOX or protocadherin 8 staining results between adenomatous hyperplasia and prostate adenocarcinoma cases were examined using a two-way chi-square test and binary logistic regression analysis. Result : Statistical analysis showed that WWOX expression was higher in adenomatous hyperplasia than in prostate adenocarcinomas. This difference was statistically significant ( p = 0.035). There was no difference in PCDH8 expression between adenomatous hyperplasia and prostate adenocarcinoma samples ( p = 0.217). Conclusion : In this study, the expression of WWOX decreased and the expression of PCDH8 remained unchanged in PCa cases. In terms of prognostic significance, it can be concluded that WWOX is a good prognostic parameter, while PCDH8 was an ineffective prognostic marker. In addition, the investigation of protocadherin 8 in larger series may provide more meaningful results.
Hava Yolu Sektöründe Varlık Değerlemesi: Hava Aracı Değerlemesi Üzerine Bir Örnek Olay İncelemesi

The valuation of aircraft is one of the important issues in the airline industry, which is a dynamic sector. The valuation of an aircraft, which is an aircraft, is under the influence of technical, economic, political, and environmental factors. The Covid-19 global epidemic, which affected and continues to affect the whole world last year, has affected the entire airline industry; continues to adversely affect aircraft production, sales, and valuation. In this study, the annual income and expenses of narrow-body B737-700 produced by Boeing, wide-body B767-300 ER and narrow-body A320-200, and wide-body A330-200 aircraft manufactured by Airbus, which are one of the world's leading aircraft manufacturer companies, are estimated and various assumptions and assumptions are made. Theoretical values (Net Present Values) were determined under the 1%discount rate and the deviation between the minimum prices and the theoretical values was between 10.24%and 17.68%. In this respect, similar results were obtained from the studies in the literature. It is considered that this deviation may change under various factors. In the study, "Theoretical Value" calculations were also made according to 2%, 5%, and 10%discount rates in order to adjust cash flows according to risk, and it was determined that the present or theoretical value of net cash flows formed in 30 years of economic life decreases as the discount rate increases. However, bringing a practical solution in line with the aircraft valuation literature makes the study important. ABSTRACT Investing in aircraft or aircraft as a tangible asset in the airline industry is a very expensive and strategic decision. After determining the types of aircraft that meet the investment criteria and therefore will be the main target asset for the investment portfolio, it is important to understand how the aircraft will perform at the stages of the industry cycle and in the long term and to make additional investments in order to increase the service life. With the deregulation the airline airlines must adapt to the risks posed by dynamic prices and cost the competitive One the most important is the value Therefore, it develop

Drinking Water Supplemented with Acidifiers Improves the Growth Performance of Weaned Pigs and Potentially Regulates Antioxidant Capacity, Immunity, and Gastrointestinal Microbiota Diversity

This study evaluated the potential effects of adding acidifiers to the drinking water on the growth performance, complete blood count, antioxidant indicators, and diversity of gastrointestinal microbiota for weaned pigs. A total of 400 weaned pigs were randomly divided into four treatments. Pigs were fed the same basal diet and given either water (no acidifier was added, control) or water plus blends of different formulas of acidifiers (acidifier A1, A2, or A3) for 35 days. On d 18 and 35 of the experimental period, 64 pigs (four pigs per pen) were randomly selected to collect blood for a CBC test (n = 128) and an antioxidant indicators test (n = 128); 24 pigs (six pigs per group) were randomly selected to collect fresh feces (n = 48) from the rectum for 16S rRNA gene sequencing. Compared to the control, supplementing the drinking water with acidifiers improved the growth performance and survival rate of weaned pigs. Acidifier groups also increased serum catalase (CAT) and total antioxidant capacity (T-AOC) activities, while also displaying a decreased malondialdehyde (MDA) concentration compared to the control. The relative abundance of Firmicutes in the acidifier A1 group was greater than that in the control group (p < 0.05) on d 35; the relative abundance of Lactobacillus in the acidifier A1 group was greater than that in the control group (p < 0.05) on d 18 and 35. The microbial species Subdoligranulum or Ruminococcaceae_UCG-005 had significantly positive correlations with ADG and ADFI or with serum antioxidant indicators, respectively. These findings suggest that supplementing the drinking water with an acidifier has a potential as an antioxidant, which was reflected in the improvement of growth performance, immunity, antioxidant capacity, and intestinal flora.
Sparse Methods for Model Estimation with Applications to Radar Imaging

In additive component model estimation problems, the number of additive components (model order) and values of the model parameters in each of the additive components are estimated. Traditional methods typically estimate parameters for a set of models with fixed order; parameter estimation is performed over a continuous space when parameters are not discrete. The model order is estimated as the minimizer, over the set of fixed model orders, of a cost function compromising between signal fit to measurements and model complexity. This dissertation explores dictionary-based estimation methods for joint model order and parameter estimation. In dictionary estimation, the continuous parameter space is discretized, forming a dictionary. Each column of the dictionary is a model component at a sampled parameter value, and a linear combination of a subset of columns is used to represent the model. It is assumed that the model consists of a small number of components, and a sparse reconstruction algorithm is used to select a sparse superposition of columns to represent the signal. The number of columns selected is the estimated model order, and the parameters of each column are the parameter estimates. We examine both static and dynamic dictionary-based estimation methods. In static estimation, the dictionary is fixed, while in dynamic estimation, dictionary parameters adapt to the data. We propose two new dynamic dictionary-based estimation
Employer Concentration and Labor Force Participation

This paper examines the association between employer concentration and labor outcomes (labor force participation and employment). It uses restricted data from the U.S. Census Bureau’s Longitudinal Business Database to estimate, at the county level, to what extent more concentrated labor markets have lower labor force participation rates and lower employment. The analysis also examines whether unionization rates and education levels mediate these
An investigation into accessible and usable web navigation for the blind people

Navigability, or ease of navigation, is important for web access by the blind community. However, current screen reader program used by blind people to access the Internet imposes navigation constraints since the blind users can only ‘hear’ the content in serial mode. Serialized access using a screen-reader program prevents blind users from experiencing the multi-dimensional effects required to fully understand the page layout. We believe that by accessing web pages using bi-modal interaction, a blind user would be able to gain a two-dimensional perspective of a web page in his or her mental model. The purpose of this study is to investigate the differences in the mental models created by blind people from a two-dimensional web page using two different means: one using a screen reader only and the other using a touch screen with audio feedback. This study utilized a mixed-method design to investigate the accessibility and usability differences between use of a screen reader and use of a touch screen with audio feedback. Ten blind people and thirty sighted and blindfolded participants participated in this study. This study employed within-subjects repeated measures experiments together with observations, verbal protocols and semi-structured questionnaires to achieve the defined objectives. Additionally, the influence of users’ spatial ability on their performance was investigated using Tactual Performance Test (TPT). This study found that expert and more experienced screen reader users were able to imagine the page layout in a two-dimensional perspective, using a touch screen with audio feedback. The study also revealed that blind users achieved more accurate orientation when using a touch screen with audio feedback. However, the accuracy of orientation seems to have been affected by page complexity. In addition, investigation of blind users’ spatial ability on their sense of position revealed that, when using a touch screen with audio feedback, blind participants with lower spatial ability took longer time to locate information. Therefore, spatial ability is an important determinant for web navigability when using a touch screen with audio feedback.
Development of a Long-Acting Injectable Formulation of Rilpivirine Based On PLGA Microspheres

The rilpivirine-loaded spherical and monodisperse PLGA microspheres were produced by microfluidic technology. The technological parameters such as the flow rate ratio and the rilpivirine/PLGA ratio were optimized to ensure desired microspheres size and higher encapsulation efficiency of rilpivirine. The microspheres exhibited a continuous drug release characterized by only a minor burst effect. These results suggest that the PLGA microspheres loaded with rilpivirine is a promising approach to the injectable depot formulation of this drug.
A novel control method for input output harmonic elimination of the PWM boost type rectifier under unbalanced operating conditions

This paper presents a new control strategy to improve the performance of the PWM boost type rectifier when operating under an unbalanced supply. An analytical solution for harmonic elimination under unbalanced input voltages is obtained resulting in a smooth (constant) power flow from AC to DC side in spite of the unbalanced voltage condition. Based on the analysis of the open loop configuration, a closed loop control solution is proposed. Simulation results show excellent response and stable operation of the new rectifier control algorithm. A laboratory prototype has been designed to verify the discussions and analyses done in this paper. Theoretical and experimental results show excellent agreement. Elimination of the possibility of low order AC and DC side harmonics due to unbalance is expected to materially affect the cost of DC link capacitor and AC side filter. The proposed method will be particularly useful in applications where the large second harmonic at the DC link may have a severe impact on system stability of multiply connected converters on a common link.
SIS infectious disease model with mean regression of mortality

This paper focuses on stochastic infectious disease models in the context of biological problems. Stochastic infectious disease models with mean-reverting processes are studied, and the model studied is a stochastic SIS infectious disease model with mean-reverting birth mortality[1-7]. The persistence and extinction of diseases are discussed in the context of the infectious disease mode[8-11]l, giving thresholds such that if the threshold is less than 1, the disease becomes extinct with probability 1, and if the threshold is greater than 1, the disease persists with probability 1 in the mean sense. From this analysis, we conclude that the greater the intensity of the fluctuation, the faster the disease goes extinct, while the smaller the intensity of the fluctuation, the greater the number of infectious diseases.
On the Energy Efficiency of Multicell Massive MIMO with Antenna Selection and Power Allocation

The energy consumption of massive multiple-input multiple-output (MIMO) systems increases with the number of antennas. Optimizing the energy efficiency (EE) of massive MIMO systems is one of the ways to achieve green communication. This paper proposes an EE optimization method that genetic algorithm-based antenna selection and power allocation (GA-AS+PA) for the downlink of a multicell massive MIMO system under the restriction of the users’ sum-rate. First, we use the genetic algorithm to determine the active transmitting antenna of each base station (BS). Then, the transmission power for each user is allocated using the convex optimization method. Finally, the EE of system is optimized under the achieved optimum BS’s transmit power and the number of active antennas. From the simulation results, the GA-AS+PA method can improve the EE of the system while meeting user sum-rate requirements, which achieves better performance compared with random antenna selection+equal power allocation method (RAS+EPA), random antenna selection+power allocation method (RAS+PA), the antenna selection method based on genetic algorithm+equal power allocation method (GA-AS+EPA), and equal power allocation (EPA) these four methods. The EE of the proposed GA-AS+PA method is improved by 33.3% compared to the EPA method.
THE INFLUENCE OF FISH MORPHOLOGICAL AND BEHAVIOURAL PARAMETERS ON ACOUSTIC DATA IN ALGORITHMIC RECONSTRUCTION OF FISH LENGTH DISTRIBUTION

The paper investigates the algorithm for estimation the fish length distribution from acoustic target strength data. The theory of scattering from a tilted cylinder is used for modelling the fish directivity pattern of swimbladdered fish. The model allows formulating the dependence of target strength on two main components: fish maximum target strength and the fish directivity pattern. As both terms depend on fish length, the inverse technique could be used to reconstruct unknown fish length distribution from acoustic data, when morphological parameters of fish are properly assumed. However, as it is shown, the algorithmic approach is very sensitive to some of behavioural parameters of swimming fish. Thus, although the effect of unknown fish tilt angle could be partially removed by statistical processing, the mean value of fish tilt angle still may produce large errors. The method and its results are verified on actual data acquired during the survey and compared to trawl catches.
Quantifying Ice Pressure Conditions and Predicting the Risk of Ship Besetting

The risks of ship besetting under ice pressure are examined. Hindcasts of ice dynamics examine the conditions that led to the besetting of two vessels in the Gulf of St. Lawrence on 9 March 2005. The analysis examines the distributions of potentially significant variables such as pressure (mean normal stress), ridge thickness and strain rates. A criterion for assessing the risk of besetting was then proposed. A preliminary parametric study was also done in order to illustrate a method for predicting the risk of besetting under different ice and environmental forcing conditions.
Rodent models in placental research. Implications for fetal origins of adult disease

Abstract Rodent models in rats, mice, and guinea pigs have been extremely helpful to gain insight into pregnancy physiology and pathologies-related. Moreover, they have allowed understanding the mechanism that links an adverse intrauterine environment with the origin of adult disease. In this regard, the effects of diverse maternal conditions, such as undernutrition, obesity, hypoxia, and hyperandrogenism on placental function and its long-term consequences for the offspring, have been widely analyzed through rodents models involving dietary manipulations, modifications in environmental oxygen, surgical and pharmacological procedures that reduce uteroplacental blood flow and administrations of exogenous testosterone and dihydrotestosterone (DHT) mimicking maternal androgen excess. Both in human and in rodent models, these interventions induce modifications of placental morphology, transport of glucose, amino acid, and fatty acids, steroid synthesis, and signaling pathways control placental function. These changes are associated with the increase of pro-inflammatory and oxidative stress markers. For its part, offspring exhibit alterations in organs involved in metabolic control such as the hypothalamus, adipose tissue, liver, skeletal muscle, and pancreas altering the intake and preferences for certain foods, the metabolism of glucose and lipid, and hormonal function leading to fat accumulation, insulin resistance, fatty liver, dyslipidemia, and elevated glucose levels. Therefore, the present review discusses the evidence emerging from rodent models that relate maternal nutrition, hypoxia, and androgen exposure to the maternal mechanisms that lead to fetal programming and their metabolic consequences in postnatal life.
