Carbon dioxide (CO2) is the most significant greenhouse gas, contributing 44% of global warming using coal combustion for electricity generation. The major goal is to reduce carbon dioxide emissions by using the carbon dioxide capture and storage (CCS) technique. Among various techniques, amine-based post-combustion carbon dioxide capture plays a critical role in CCS technology. Monoethanolamine (MEA) acts as a benchmarking solvent in the CCS process owing to its high absorption capacity, lower cost and high rate of reaction. The present investigation used 30 wt% MEA and animised flue gas (15 vol% carbon dioxide and resting nitrogen (N2) gas) at 0.5 pound/square inch (3.45 kPa) inlet pressure for carbon dioxide absorption followed by 1 h solvent regeneration (direct and indirect heating). Furthermore, measurements of physico-chemical properties such as pH, carbon dioxide loading, density, viscosity, alkalinity and surface tension and Fourier transform infrared (FTIR) spectroscopic analysis of unloaded, carbon dioxide-loaded and regenerated samples were carried out. During carbon dioxide absorption, a rich loading of 7.775 mol/kg was obtained, whereas after regeneration, lean loadings of 3.099 and 3.937 mol/kg were achieved. FTIR analysis of the regenerated sample reconfirmed carbamate and bicarbonate presence, indicating that the sample required further regeneration. An increase in density, viscosity and surface tension was observed during carbon dioxide loading due to stronger intermolecular forces between the solvent and carbon dioxide molecules, and a decrease was observed during solvent regeneration due to carbon dioxide stripping.

Authors: Higuita-López Daimer
Published: June 2020

Objetivo: Analizar las representaciones sociales que se construyen directivos y empleados en el proceso de capacitación.  Método: investigación cualitativa en la que se aplicaron entrevistas a 18 directivos del área de gestión humana y a 33 trabajadores de varios sectores económicos en la ciudad de Medellín. Para la construcción de las representaciones, se utilizó la carta asociativa, cuya finalidad fue identificar las características de la capacitación. Resultados: se encontró que en la representación de los directivos, la capacitación es una estrategia que permite alinear al empleado y fortalecer aquellas habilidades que generen valor para la compañía. En cuanto a la representación de los trabajadores, la capacitación está asociada al conocimiento que reciben y al valor que sienten por parte de la organización al momento de capacitarlos. Discusiones: No es sencillo trazar una línea causal entre capacitación y rendimiento individual, como sugieren los textos de recursos humanos, porque las empresas que desarrollan capacitación evalúan solamente la percepción y el aprendizaje pero no evalúan la aplicación de conocimientos ni los resultados de la capacitación en términos de desempeño. Conclusiones: Entre trabajadores y directivos existe esa representación, es decir, esa idea de causalidad entre capacitación y rendimiento. Igualmente, la sola existencia de la capacitación es asumida como una muestra de que los trabajadores son importantes para las empresas.

The phenomenal discourse on People Power after Pemilu 2019 is an opinion that was initiated by a central figure in Indonesia, namely Amien Rais. This discourse invited many responses, one of which was Yusril Ihza Mahendra. Yusril gave his argument about various complicated situations and the risk of governance under the umbrella of provocation of people power. The problem of this research is how is the structure of the text and the social context that builds Yusril's opinion on the discourse of people power? This research includes descriptive qualitative research. The approach used is the critical discourse analysis model Teun A. Van Dijk. The data analysis method used is the equivalent and contextual method. Data presentation is done informally. Based on the results and discussion, it can be concluded that: (1) the structure of the text describes semantic, syntactic, and stylistic aspects; while (2) the social context that builds the discourse of People Power is the power and access that the author has.

POLITICAL AND LEGAL MODEL OF STATE-CHURCH RELATIONS AS THE BASIS OF REGULATION OF RELATIONS BETWEEN THE STATE AND RELIGIOUS ORGANIZATIONS
Authors: Vyhovskyi Leonid
Published: June 2020

The author shows that a specific type of political-legal model of state-church relations plays a decisive role in the process of regulating relations between the state and the church in the historical-legal context, since it determines the content and form of such relationships. It is shown that three primary typological models have formed the basis for relations between the state and the church during the history of the mankind: the unitary model (the state structures are subordinated to the church); the so-called "two swords" model (relations between the state and the church are recognized as parity relations between autonomous institutions); and the trinitarian model (a clear separation of functions between the state and the church). Other models of such relationships present in society are derivatives of the above-mentioned ones. The essence of political and legal types of models of state-church relations existing in the world are analyzed. The principles are described and the necessity to develop a cooperative model of state-church relations in the state and to formalize in legislation is substantiated. The content of the models that took place in the history of Ukraine (the Kyiv-Rus model, the Kozak-Mohyla model and the model of coexistence of the church with the communist authorities) is described. It is pointed out that the basic component of the existing Ukrainian model of state-church relations is that the state and the Church are defined as equal subjects of state-church relations. Therefore, each of them acts within its specific competencies, mutually supporting each other in matters concerning the jurisdiction of these social institutions. It is argued that, at the same time, religious organizations operate in the legal field of the state, and the latter does not interfere in the affairs of the Church. Thus, freedom of conscience in the country is ensured and this creates favorable conditions for religious organizations. In conclusion, the author points out that in recent years Ukraine has not only theoretically developed cooperative models of interaction of the state with religious institutions and organizations, but also carried out practical measures for their implementation.
SEPARATION ON THE JURISDDICTION OF MODERN UKRAINIAN ORTHODOX
Authors: Коbetіak Andrii
Published: June 2020

The article deals with the problem of the current jurisdictional division of Ukrainian Orthodoxy into three main branches. During the years of independence, our crew never received a long-awaited religious reconciliation. Today, Ukraine is one of the largest Orthodox countries in the world. Since 1991, Orthodox churches, which are different in their jurisdiction, operate in parallel, and they are not mutually recognized and opposed to each other. Having a common Volodymyr christening and being the same or similar in content, they differ in their own institutionalization in Ukrainian society. The process and conditions of historical formation and the moment of occurrence are analyzed; universal and all-Orthodox recognition; institutionalization as a socially important element; modern development; distribution and transformation during the years of independence of the parish network of each of the Orthodox churches represented in Ukraine. It has been established that the canonical recognition of the newly formed Orthodox Church of Ukraine will contribute to the consolidation of the Ukrainian nation and the strengthening of the independence of the state. This is extremely important for the formation of a new civil society in Ukraine. Moreover, the new united church is one of the indispensable elements of the establishment of Ukrainian statehood and its weight in the international arena. At the same time, there are a number of unresolved issues. In itself, Tomos did not combine all branches of Orthodoxy into a single church at this time. Problems of simony, dominance of the episcopate in comparison with priests, Sodom sin, super-luxurious bishop's life, church extortion, low level of general and spiritual education of the majority of clergy, lack of official employment of the clergy, extracurricular profitable activity of clergy and others remain unsolved. At the beginning of 2019, the jurisdictional separation continues. The pro-Russian church in the vast majority of dioceses and parishes does not participate in the process of association. Only the beginning of the CSP as a legal entity and its official registration have begun. Delegates are expected to be nominated and the first Organizing Synod of the newly formed church structure is to be convened. It is important to declare its existence, but to achieve its recognition by all the local churches of the world without a real and complete unification of the currently divided Orthodox churches in Ukraine will be difficult. Therefore, the in-depth analysis of the jurisdictional division of Ukrainian Orthodoxy in its historical section will give an opportunity to explain as much as possible the essence and reasons for the distinction for their possible elimination and further unification.

Diagnostic efficacy of FNAC by liquid based technique versus conventional smear in lung and mediastinal masses
Authors: Singh Rekha , Mittal Vani , Bali Irbinder Kour , Arora Sunil , Kumar Raj
Published: June 2020

Background: Fine Needle Aspiration Cytology (FNAC) has proven to be less costly and less invasive procedure than biopsy for diagnosing benign and malignant lesions. Of the two methods liquid based cytology (LBC) and conventional cytology (CC), LBC has been standardized as more efficacious in reporting in Gynaecological cases. But, this is still lacking in non-gynaecological cases and many studies are now focusing on studying LBC due to its proven advantages in Pap smear evaluation.Methods: An observational study of 72 patients with lung mass and 11 with mediastinal mass was done for a period of six months in a tertiary care hospital in Gurugram to compare the diagnostic efficacy of LBC and CC in fine needle aspirates from lung/mediastinal mass.Results: Of the 83 cases, reporting of LBC was adequate in 75 cases and CC in only 53 cases. LBC was better when differentiating malignant and benign lesions than CC. CC smears had better cellularity in comparison to LBC smears (36%), but rest cytological features of cytoplasmic detailing, cell architecture, less background debris and blood were all more appreciable in LBC smears than CC preparations.Conclusions: LBC is a better method than conventional smear for smear preparation and processing of aspirates obtained from lung and mediastinal mass.

Authors: Bharti Laxmi Kant , . Neelu
Published: June 2020

Background: Acute viral hepatitis (AVH) is one of the common infections in developing nation. Hepatotrophic virus causes AVH and most of the time it has self-limiting course. HAV is most common cause of AVH. Suboptimal dietary cultural practices are common in our nation. This study was done to know the impact of suboptimal dietary practices done in AVH.Methods: Observational study conducted with 50 children with AVH. Dietary assessment was done at three point of time.  First During AVH, second, pre illness and then two weeks after nutritional counselling. Data of dietary modification done by parents/caregiver during AVH recorded. History of herbal medicine taken for treatment of AVH enquired.Results: HAV positive was (72%), HEV positivity was in 8 (16%) cases, hepatitis B was positive in 4 (8%) children and dual infection HAV+HEV was detected in 2 (4%) children. Many parents did dietary modification due to AVH and also by some local treating physicians, 18 (36%) patients were also on herbal medication for treatment of AVH. During AVH the mean calorie and protein requirement decreased from 96% to 54% and 92% to 43% respectively. Two weeks after nutritional counseling the mean calorie and protein intake increased from 54% to 88% and 43% to 84% respectively. This change in calorie and protein was statistically significant (p<0.01) Non-vegetarian diet preference was restarted in many of them after nutritional counseling.Conclusions: This observational study revealed that suboptimal dietary cultural practices are prevalent in India. Majority of children were on bland diet and receiving inadequate proteins and calories.
Methionine synthase A2756G polymorphism associated with an increased risk of head and neck cancer
Authors: Tahir Muhammad , Khattak Aamir , Rashid Haroon
Published: June 2020

Background: The 5-methyltetrahydrofolate-homocysteine methyltransferase gene (MTR) encodes the methionine synthase enzyme (OMIM 156570). Methionine synthase synthesizes methionine by re-methylation of homocysteine. A single nucleotide variation MTR-A2756G may affects the function of methionine synthase enzyme, which could lead to the development of head and neck squamous cell carcinoma (HNSCC).

Methods: In current study, 292 HNSCC patients and 324 normal individuals without any history of cancer (control) were enrolled. EDTA whole blood samples of patients and control individuals were collected, and DNA was extracted. All samples were genotyped for MTR-A2756G polymorphism using polymerase chain reaction-restriction fragment length polymorphism. Frequency of polymorphism was compared between HNSCC patients and control individuals. The association of MTR-A2756G polymorphism with risk factors was statistically analysed through multivariate analysis (multiple logistic regression) whereas univariate analysis (chi square) was performed for group comparisons.  

Results: Univariate analysis revealed that the frequency of groups like age, smoking and MTR-A2756G genotype was different in HNC patients and controls (p value <0.05). Multivariate analysis showed that smoking (adjusted OR, 3.7; 95% CI, 2.3-6.0), age groups 41-50 years (adjusted OR, 3.6; 95% CI, .9-6.7) and >60 years (adjusted OR, 3.5; 95% CI, 1.7-7.3), MTR-A2756G genotype (adjusted OR, 2.1; 95% CI, 1.3-3.5) is associated with increased risk of HNSCC.

Conclusions: Our data suggests that the MTR-A2756G polymorphism is associated with the occurrence of HNSCC in Pakistani population while the individuals between 40 to 50 years of age and tobacco smokers are at a greater risk of developing HNSCC.

Authors: Gupta Anchal , Jamwal Padam Singh
Published: June 2020

Background: Transcanal myringoplasty has the advantages of demanding lower operative time and minimal external incisions. It can be performed using the microscopic or endoscopic approach.

Methods: This retrospective study was conducted in the Department of ENT and Head and Neck Surgery, SMGS Hospital, Jammu from January 2018 to January 2020. Patients attending ENT OPD with central dry perforation of tympanic membrane were selected for endoscopic transcanal myringoplasty. Written and Informed consent were taken. During surgery, various parameters were noted including duration of surgery and hospitalization. These patients were followed through a period of 6 months and assessed using pure tone audiometry and graft uptake was seen.  

Results: Out of 40 patients, male: female ratio was 1.2:1. Time taken for surgery was less than 60 minutes in 16 (40%) patients whereas in 24 (60%) patients it was between 60-120 minutes. In our study the patients with small perforation had excellent graft uptake rates (18/19 patients, 94.73%), whereas patients with medium sized perforation showed graft uptake rate of 76.47% (13/17 patients). Objective analysis of cosmetic result was done at the end of six month and revealed that none of the patient had visible scar. Mean pre-operative air bone gap was 24.38 dB whereas mean postoperative air bone gap was 8.34 dB. Mean improvement comes out to be 16.04 dB.

Conclusions: Endoscopic myringoplasty was found to be equally effective, less morbid and very cost effective in small central perforations.

Introduction: Alexithymia is a construct characterized by a subclinical inability to identify and describe emotions and an externally-oriented thinking. Objective: To test the three-dimensional theoretical model proposed by Parker et al. (1994) (DDF, DIF, EOT), when evaluated by a brief version of the Toronto Alexithymia Scale (BbTAS-12). Method: BbTAS-12 was used in a sample of 801 adolescents (from 13 to 19 years of age), of both genders (52.1% male), in order to test its first evidences of validity via Exploratory Structural Equation (ESEM) Modeling and the internal consistency index. Results: The results of the general model (GFI = .99; AGFI = .97; χ2/gl = 1,14; RMSEA = .035; PCLOSE > .5; CFI = .98; TLI = .97), are excellent and explain 51% of the construct variance, confirming also the three dimension-structure. Both the internal consistency of the total (αt = .72; Omegat = .69) and the theoretically proposed dimensions (αDDF = .67; OmegaDDF = .68; αDIF = .73; OmegaDIF = .73; αEOT = 0,56; OmegaEOT = .57) showed results varying from acceptable to adequate. The internal consistency of the full scale (BbTAS-12) is adequate, with the exception of the EOT dimension. The results are discussed considering the studies conducted with this population in several countries. Conclusion: BbTAS-12 is an especially promising scale for the measure Alexithymia in Brazilian adolescents. However, itis possible to improve the content of some items considering the reading skills and the cultural context of adolescents.

The presented analysis of multisite, multiplatform clinical oncology trial data sought to enhance quantitative utility of the apparent diffusion coefficient (ADC) metric, derived from diffusion-weighted magnetic resonance imaging, by reducing technical interplatform variability owing to systematic gradient nonlinearity (GNL). This study tested the feasibility and effectiveness of a retrospective GNL correction (GNC) implementation for quantitative quality control phantom data, as well as in a representative subset of 60 subjects from the ACRIN 6698 breast cancer therapy response trial who were scanned on 6 different gradient systems. The GNL ADC correction based on a previously developed formalism was applied to trace-DWI using system-specific gradient-channel fields derived from vendor-provided spherical harmonic tables. For quantitative DWI phantom images acquired in typical breast imaging positions, the GNC improved interplatform accuracy from a median of 6% down to 0.5% and reproducibility of 11% down to 2.5%. Across studied trial subjects, GNC increased low ADC (<1 µm2/ms) tumor volume by 16% and histogram percentiles by 5%–8%, uniformly shifting percentile-dependent ADC thresholds by ∼0.06 µm2/ms. This feasibility study lays the grounds for retrospective GNC implementation in multiplatform clinical imaging trials to improve accuracy and reproducibility of ADC metrics used for breast cancer treatment response prediction.
Deep Feature Stability Analysis Using CT Images of a Physical Phantom across Scanner Manufacturers, Cartridges, Pixel Sizes, and Slice Thickness

Published: June 2020

Image acquisition parameters for computed tomography scans such as slice thickness and field of view may vary depending on tumor size and site. Recent studies have shown that some radiomics features were dependent on voxel size (= pixel size × slice thickness), and with proper normalization, this voxel size dependency could be reduced. Deep features from a convolutional neural network (CNN) have shown great promise in characterizing cancers. However, how do these deep features vary with changes in imaging acquisition parameters? To analyze the variability of deep features, a physical radiomics phantom with 10 different material cartridges was scanned on 8 different scanners. We assessed scans from 3 different cartridges (rubber, dense cork, and normal cork). Deep features from the penultimate layer of the CNN before (pre-rectified linear unit) and after (post-rectified linear unit) applying the rectified linear unit activation function were extracted from a pre-trained CNN using transfer learning. We studied both the interscanner and intrascanner dependency of deep features and also the deep features' dependency over the 3 cartridges. We found some deep features were dependent on pixel size and that, with appropriate normalization, this dependency could be reduced. False discovery rate was applied for multiple comparisons, to mitigate potentially optimistic results. We also used stable deep features for prognostic analysis on 1 non–small cell lung cancer data set.

Published: June 2020

We investigated the impact of magnetic resonance imaging (MRI) protocol adherence on the ability of functional tumor volume (FTV), a quantitative measure of tumor burden measured from dynamic contrast-enhanced MRI, to predict response to neoadjuvant chemotherapy. We retrospectively reviewed dynamic contrast-enhanced breast MRIs for 990 patients enrolled in the multicenter I-SPY 2 TRIAL. During neoadjuvant chemotherapy, each patient had 4 MRI visits (pretreatment [T0], early-treatment [T1], inter-regimen [T2], and presurgery [T3]). Protocol adherence was rated for 7 image quality factors at T0–T2. Image quality factors confirmed by DICOM header (acquisition duration, early phase timing, field of view, and spatial resolution) were adherent if the scan parameters followed the standardized imaging protocol, and changes from T0 for a single patient's visits were limited to defined ranges. Other image quality factors (contralateral image quality, patient motion, and contrast administration error) were considered adherent if imaging issues were absent or minimal. The area under the receiver operating characteristic curve (AUC) was used to measure the performance of FTV change (percent change of FTV from T0 to T1 and T2) in predicting pathological complete response. FTV changes with adherent image quality in all factors had higher estimated AUC than those with non-adherent image quality, although the differences did not reach statistical significance (T1, 0.71 vs. 0.66; T2, 0.72 vs. 0.68). These data highlight the importance of MRI protocol adherence to predefined scan parameters and the impact of data quality on the predictive performance of FTV in the breast cancer neoadjuvant setting.

Published: June 2020

We aimed to assess longitudinal changes in quantitative imaging metric values obtained from diffusion-weighted (DW-) and dynamic contrast-enhanced magnetic resonance imaging (DCE)-MRI at pre-treatment (TX[0]), immediately after the first fraction of stereotactic body radiotherapy (D1-TX[1]), and 6 weeks post-TX (Post-TX[2]) in patients with pancreatic ductal adenocarcinoma. Ten enrolled patients (n = 10) underwent DW- and DCE-MRI examinations on a 3.0 T scanner. The apparent diffusion coefficient, ADC (mm2/s), was derived from DW imaging data using a monoexponential model. The tissue relaxation rate, R1t, time-course data were fitted with a shutter-speed model, which provides estimates of the volume transfer constant, Ktrans (min−1), extravascular extracellular volume fraction, ve, and mean lifetime of intracellular water protons, τi (seconds). Wilcoxon rank-sum test compared the mean values, standard deviation, skewness, kurtosis, and relative percentage (r, %) changes (Δ) in ADC, Ktrans, ve, and τi values between the magnetic resonance examinations. rADCΔ2–0 values were significantly greater than rADCΔ1-0 values (P = .009). rKtransΔ2–0 values were significantly lower than rKtrans Δ1-0 values (P = .048). rveΔ2-1 and rveΔ2-0 values were significantly different (P = .016). rτiΔ2-1 values were significantly lower than rτiΔ2-0 values (P = .008). For group comparison, the pre-TX mean and kurtosis of ADC (P = .18 and P = .14), skewness and kurtosis of Ktrans values (P = .14 for both) showed a leaning toward significant difference between patients who experienced local control (n = 2) and failed early (n = 4). DW- and DCE-MRI-derived quantitative metrics could be useful biomarkers to evaluate longitudinal changes to stereotactic body radiotherapy in patients with pancreatic ductal adenocarcinoma.

The Role of Bronchoscopy in Hemoptysis
Authors: Sakina Sakina , Syafa'ah Irmi
Published: June 2020

Massive hemoptysis is a medical emergency that requires intensive treatment with appropriate therapy. The underlying causes of hemoptysis are airway disease, parenchymal disease, and vascular disease. An appropriate diagnostic modality is needed in handling hemoptysis, one of which is by bronchoscopy. Bronchoscopy can identify whether bleeding is still active and see the condition of the patient’s respiratory tract. Apart from being a diagnostic tool, bronchoscopy is also used as one of the therapeutic methods to stop bleeding. Initial bronchoscopy should be performed on massive hemoptysis after the patient is stable and the other side of the lung that is not the source of bleeding has been protected. After the source of bleeding is seen, several therapies can be done.

The factors that influence complaints of contact dermatitis are Personal hygiene and the frequency of contact of motor vehicle washing workers. Purpose : This study aims to determine the relationship between personal hygiene and the frequency of contact with complaints of contact dermatitis. Method: This study was an observational analytic study, with a cross-sectional design. Respondents from the study were motor vehicle washing workers in Jebres and Mojosongo Surakarta with 35 respondents from 60 workers. The sampling technique uses purposive sampling. This study used a questionnaire base on the title and analyzing data uses the Somers' test and the Logistic Regression test. Results: The Somers' correlation test results showed a significant relationship between personal hygiene and complaints of contact dermatitis with a p-value of 0.000, the direction of correlation (-), and a correlation coefficient of 0.662. The test results also showed a significant relationship between the frequency of contact with complaints of contagious dermatitis with a p-value of 0.000, the direction of correlation (+), and the correlation coefficient 0.726. The results of the logistic regression test showed that the contact frequency variable had the most influence on complaints of contact dermatitis with an odds ratio of 28,078. Conclusion: There is a significant relationship between personal hygiene and the frequency of contact with complaints of contact dermatitis.

Backgroud: Non-ergonomic work posture at work will risk the occurrence of occupational diseases and occupational accidents. One complaint due to work is low back pain (LBP) which is a pain that is felt on the lower back. Purpose:  to determine the relationship of work posture with subjective complaints low back pain at PT X. Method: Research method is analytic with cross sectional research design. Sampling was done with total sampling of 53 samples. Assessment of work posture with rapid entire body assessment (REBA) method and subjective subjective complaints assessment of low back pain using modified questionnaire oswestry low back pain disability. Statistical test used spearman correlation test. The frequency distribution of job posture assessment with reba method is 35 respondents have medium value and 10 has high value, while for low back pain complaint there are 36 respondents who have severe crippled disability category. Results: The results showed there was a significant relationship between posture work with low back pain complaints with p value = 0.047 and r = 0.282. Conclusion: From the work posture assessment that for workers who have medium and high risk Reba for immediate action such as repair of work stations and providing understanding of ergonomic work positions.
Apex-Vigne: A mobile application to facilitate the monitoring of growth and estimate the water status of the viticulture plots

The observation of apex growth is a simple method that was introduced to monitor the existence of hydric constraints in the vineyard (Rodriguez Lovelle et al., 2009; De Toda et al., 2010). Based on the direct observation in each plot, it represents a particularly interesting approach for the wine sector because it is easy to implement and inexpensive (Saurin et al., 2014).  However, despite its advantages, the method of apex has its own implementation limits that hinder its acceptance and broader use amongst winegrowing professionals. One of its principle limitations is the need to note and memorize the apex counts plot by plot as well as the need to undertake a calculation of the indexes from these counts (Brunel et al., 2019).  The objective of the Apex-Vigne application is to propose a free tool that will eliminate these constraints and thus favor the adoption and use of the apex method.
Acetaldehyde metabolism in industrial strains of Saccharomyces cerevisiae inhibited by SO2 and cooling during alcoholic fermentation
Authors: Li Erhu , Mira de Orduña Heidinger Ramón
Published: June 2020

Aim: The addition of SO2 is a common technique for stopping alcoholic fermentation by Saccharomyces cerevisiae and producing beverages with residual sugar. However, SO2 causes a metabolic shift in active yeast leading to the formation of acetaldehyde and resulting in higher preservative SO2 requirements in the final product. The current work investigated the effects of stopping alcoholic fermentation using two industrial strains of Saccharomyces cerevisiae, by means of cooling and/or addition of SO2, on the kinetics of hexoses and acetaldehyde.Methods and results: Alcoholic fermentation was conducted by inoculating natural Chardonnay grape must with two commonly used strains of Saccharomyces cerevisiae (CY3079 and EC1118). Ten days after inoculation, cooling (to 4 °C) and/or addition of SO2 (50-350 mg/L) were applied to stop fermentations at approximately 70-90 g/L of residual sugar. Incubations were carried out in an anaerobic chamber to prevent the formation of acetalhdeyde resulting from chemical oxidation. Samples were taken regularly and analysed for glucose, fructose and acetalhdyde levels.In this work, addition of SO2 to 150 mg/L or more were effective in inhibiting further and practically relevant degradation of hexoses even in non-cooled control treatments. With concurrent cooling, an addition to 50 mg/L was sufficient. Addition of SO2always led to a slow increase in yeast acetaldehyde formation over time, regardless of cooling or the apparent inhibition of yeast sugar metabolism. Acetaldehyde increases were reduced with larger SO2 additions.Conclusions: When using SO2 to stop alcoholic fermentations, large doses should be used and wines separated from the sedimented biomass soon thereafter. Nevertheless, rapid cooling remains preferable to SO2 addition and can prevent further microbial formation of acetaldehyde.Significance and impact of the study: Results from the current work show that acetaldehyde, and therefore bound SO2formation, can be reduced when alcoholic fermentation is halted to obtain wines with residual sweetness.
Productivité et qualité du poulet de chair

Published: June 2020

Le poulet de chair a connu une amélioration spectaculaire de sa productivité, grâce aux progrès concomitants des méthodes d’élevage, de la nutrition, de la génétique et de la médecine vétérinaire. Ces progrès se sont traduits par une forte réduction de l’âge à l’abattage, principal déterminant de la qualité sensorielle de la viande. Ce critère a été le principal élément de la segmentation qualitative de la filière. Débutée dès les années 1960, celle-ci a conduit à la différenciation entre poulets standard, d’appellation d’origine contrôlée, Label et certifiés.
Un second axe de segmentation, plus récent, porte sur le degré d’élaboration des produits : vente sous forme de carcasses, de morceaux de découpe ou de produits élaborés et ce sont ces deux derniers types de produits qui se développent aujourd’hui.
La productivité des produits standard est la plus élevée, mais l’écart avec celle du poulet certifié apparaît assez réduit et pourrait être compensé par les garanties de traçabilité et production qu’apporte la certification. En terme de qualité aussi, une partie des différences s’estompent, parce que les préférences du consommateur évoluent et que la différence de goût est surtout marquée pour les cuisses, moins bien valorisées que les filets. Les différences d’aptitude à la transformation sont en faveur des souches à croissance rapide. Par ailleurs, si les animaux peuvent davantage exprimer leur comportement naturel sur parcours, ils courent un risque accru de contamination microbienne.
Face à ce bilan contrasté, il semble difficile de prédire l’avenir de la production avicole. Mais il apparaît clairement que le poulet certifié, intermédiaire entre poulet standard et poulet Label se développera fortement.
