Le travail de l’Homme-machine et les promesses d’abondance
Authors: Jorda Henri
Published: October 2018

À partir du xix e  siècle, la machine permet de rêver d’une société où personne ne manque de rien, où l’automatisation rend le travail moins pénible et fait disparaître les tâches les plus serviles. Ce monde, imaginé par Andrew Ure dès les années 1830 et par Norbert Wiener dans les années 1950, n’est pas celui de l’organisation capitaliste du travail où l’Homme-machine est destiné à être un rouage efficace, condamné à travailler toujours plus vite dans le respect des procédures. Ainsi, l’Homme-machine contient des promesses d’abondance, mais engage aussi des mécanismes de savoir et de pouvoir, et une autre promesse énoncée par Foucault, celle de l’effacement de l’humanité, quand la mécanisation des êtres ne concerne plus seulement leur corps mais leurs décisions.

Pour le développement d’une linguistique ergonomique : l’exemple des langues contrôlées
Authors: Condamines Anne
Published: October 2018

Cet article vise à définir la linguistique ergonomique comme un domaine de la linguistique qui, en s’appuyant sur l’expérience de l’ergonomie, cherche à répondre à des besoins spécifiques, tout en mettant en œuvre une approche scientifique. Le concept d’utilisabilité, central en ergonomie car il place l’humain au cœur des besoins, est particulièrement adapté à la perspective de la linguistique ergonomique. Afin de mettre en œuvre cette branche de la linguistique au travail, nous proposons, d’une part, de baser les études sur des corpus (usage réel de la langue, en situation), et, d’autre part, de mettre en place des tests pour évaluer la pertinence des propositions de « normalisation » qui sont faites. Nous focalisons notre intérêt sur l’évaluation et la constitution des langues contrôlées, qui sont considérées comme une des façons de limiter les risques liés à l’utilisation de la langue dans les organisations. Trois études réalisées dans les domaines de de l’aéronautique et de l’espace et prenant pour objet la question des langues contrô­lées sont présentées. Elles permettent d’aborder différents aspects de l’utilisabilité des langues contrôlées.
Approach to Children with Aggressive Behavior for General Pediatricians and Hospitalists: Part 2—Evaluation, Tests, and Treatment
Authors: Haidar-Elatrache Sara , Wolf Marlisa , Fabie Noelle Andrea V. , Sahai Shashi
Published: October 2018

After reviewing the various etiologies that can contribute to a presentation of aggressive behavior in a child (see part 1), a physician should conduct a thorough history and physical examination. The history should be obtained from the patient and caregivers, both together and separately in adolescents. A good physical examination starts with assessment and interpretation of vital signs, followed by a head-to-toe examination focusing on the skin, eyes, and thyroid, and then a neurologic examination. The testing and observation should be tailored to the individual patient, including laboratory results, imaging, and specialist consultation. Management of aggressive behavior can often be achieved through a combination of environmental modifications and verbal techniques, with special consideration given to children with neurodevelopmental problems such as autism. Pharmacologic agents are a good next step, and physical restraints can be used as a last resort. Evaluation of suicidality with thorough and complete questioning as well as assessment of a safety plan can aid in determining patient disposition such as need for admission to a psychiatric facility.

Advocating for Automatic Eligibility for Early Intervention Services for Children Exposed to Lead
Authors: Hamp Nicole , Zimmerman Amy , Hoffen Jessica
Published: October 2018

Lead poisoning remains one of the most prevalent and preventable environmental health hazards affecting children. Low-level lead exposure has been shown to significantly increase the risk of learning disabilities, behavioral problems, and developmental delay. It also has substantial social implications as lead toxicity disproportionately affects children from low-income, ethnic minority households. Early Intervention (EI) is a state-based federal program (Part C of the Federal Individuals with Disabilities Education Act) created to support the development of children from birth to age 3 years who are experiencing or who are at risk for developmental delay. In 2016, an Illinois EI and Lead Workgroup was established to address the best practice of offering EI services to children who have been exposed to lead. This work serves as a template for advocates and health providers in other states to establish automatic eligibility for EI services at low levels of lead exposure, while also demonstrating the capacity to serve these children without overwhelming the state's EI system.

A Universal Image Forensics of Smoothing Filtering
Authors: Peng Anjie , Yu Gao , Wu Yadong , Zhang Qiong , Kang Xiangui
Published: October 2018

Digital image smoothing filtering operations, including the average filtering, Gaussian filtering and median filtering are always used to beautify the forged images. The detection of these smoothing operations is important in the image forensics field. In this article, the authors propose a universal detection algorithm which can simultaneously detect the average filtering, Gaussian low-pass filtering and median filtering. Firstly, the high-frequency residuals are used as being the feature extraction domain, and then the feature extraction is established on the local binary pattern (LBP) and the autoregressive model (AR). For the LBP model, the authors exploit that both of the relationships between the central pixel and its neighboring pixels and the relationships among the neighboring pixels are differentiated for the original images and smoothing filtered images. A method is further developed to reduce the high dimensionality of LBP-based features. Experimental results show that the proposed detector is effective in the smoothing forensics, and achieves better performance than the previous works, especially on the JPEG images.
Asymmetric Distortion Function for JPEG Steganography Using Block Artifact Compensation
Authors: Wang Zichi , Yin Zhaoxia , Zhang Xinpeng
Published: October 2018

This article describes how the existing distortion functions for JPEG steganography allot same cost for ±1 embedding changes. Because of the correlation of natural image, however, changes with different polarities make different influences on image. Therefore, the embedding costs for ±1 embedding changes should not be equivalent. This article proposes a general method to distinguish the embedding costs for different polarities of embedding changes for JPEG images with the help of reference images constructed by block artifact compensation. The original JPEG image is decompressed into spatial domain firstly, and then the block artifact is compensated by smoothing filtering implemented on border pixels of each 8 × 8 block. After that, the compensated image which is more similar to the original uncompressed image is recompressed into DCT domain and adopted as side information to guide the adjusting of the given distortion function. Experiment results show that after the proposed method is employed, the security performance of current popular JPEG steganographic methods is observably increased.

The response rate was 100% for the first eight panels, and the number of technicians with a test score of 100% increased during the first three panels. Based on the evaluations of the technicians, the quality of testing for early infant diagnosis of HIV improved over time in the laboratories.
A literary figure or patriarchal reality? Reflections on the ‘ēšet hayil in light of depictions of womanhood from selected Yorùbá and Sotho proverbs
Authors: Masenya Madipoane
Published: October 2018

In varying Jewish and African contexts (cf. the Yorùbá and Sotho in the present essay), the ‘ēšet hayil is regarded as a historical figure who should serve as a model for women both young and old. As an organic scholar within an African context, I am both fascinated and also challenged by how biblical notions of gender and womanhood, as portrayed in the paean on the ‘ēšet hayil in Proverbs 31:10–31, seem to be at variance with notions of gender and womanhood as depicted in some Yorùbá and Sotho proverbs. Noting the emphasis in Proverbs 31:10–31 on the positive image of the ‘ēšet hayil as the ideal wife, this article shows that overall, in the African proverbs, the woman is depicted positively as a mother, though many proverbs (cf. especially the Yorùbá proverbs) cast the woman as a wife in a negative light. It is argued that the epitome of womanhood, which in Proverbs 31:10–31 is the ideal wife, appears to stand in tension with the image of a good mother and of a bad wife observed in some of the African proverbs. This article therefore focuses on the kind of gender- and family-conscious hermeneutic that may be envisioned when Proverbs 31:10–31 is read in the Yorùbá and Sotho contexts.Intradisciplinary and/or interdisciplinary implications: The research carried out in this article entails Old Testament Studies, Gender Studies and African Languages. Sotho and Yorùbá proverbs on womanhood are used as a hermeneutical lens to interrogate the text of Proverbs 31:10–31, resulting in fresh insights on womanhood. The resultant output makes a needed contribution in challenging patriarchal ideologies and contexts.
An algorithm to retrieve ice water content profiles in cirrus clouds
from the synergy of ground-based lidar and thermal infrared
radiometer measurements
Authors: Hemmer Friederike , C.-Labonnote Laurent , Parol Frédéric , Brogniez Gérard , Damiri Bahaiddin , Podvin Thierry
Published: October 2018

Abstract. The algorithm presented in this paper was developed to retrieve ice water content (IWC) profiles in cirrus clouds. It is based on optimal estimation theory and combines ground-based visible lidar and thermal infrared (TIR) radiometer measurements in a common retrieval framework to retrieve profiles of IWC together with a correction factor for the backscatter intensity of cirrus cloud particles. In a first step, we introduce a method to retrieve extinction and IWC profiles in cirrus clouds from the lidar measurements alone and demonstrate the shortcomings of this approach due to the backscatter-to-extinction ambiguity. In a second step, we show that TIR radiances constrain the backscattering of the ice crystals at the visible lidar wavelength by constraining the ice water path (IWP) and hence the IWC which is linked to the optical properties of the ice crystals via a realistic bulk ice microphysical model. The scattering phase function obtained from the microphysical model has a flat ending without backscattering peak. We show that retrievals with the lidar only algorithm using this phase function in backscattering direction to define the backscatter-to-extinction ratio of the ice crystals result in an overestimation of IWC which is inconsistent with the TIR radiometer measurements. Hence, a synergy algorithm was developed that combines the profiles of backscattering measured by the lidar and the measurements of TIR radiances in a common optimal estimation framework to retrieve together with the IWC profile a correction factor for the phase function of the bulk ice crystals in backscattering direction. We show that this approach allows to simultaneously converge towards the measurements of two independent instruments and that the first results of the retrieved lidar ratios for cirrus clouds agree with previous studies.

Authors: Caviezel Andrin , Demmel Sophia E. , Ringenbach Adrian , Bühler Yves , Lu Guang , Christen Marc , Dinneen Claire E. , Eberhard Lucie A. , von Rickenbach Daniel , Bartelt Perry
Published: October 2018

Abstract. A comprehensive understanding of rockfall trajectories holds the promise to enhance the application of numericalmodels for engineering hazard analysis. Here, we present a full three-dimensional trajectory reconstruction of the Chant Sura EOTA221 rockfall experiment. The data analysis allows a complete kinematic description of a rock’s trajectory in real terrain and underscores the physical complexity of rock-ground interactions. In-situ accelerometer and gyroscope data are combined with videogrammetric and unmanned aerial systems mapping techniques to understand the role of rock rotations, ground penetration and translational scarring in rockfall motion. The exhaustive trajectory reconstruction provides information over the complete flight path such as translational velocity vectors, angular velocities, impact duration and forces, ballistic jump heights and lengths. The experimental data provides insight into the basic physical processes detailing how rotating rocks of general shape penetrate, rebound and scar ground terrain. The data serves in future as a calibration basement to enhance numericalrockfall modelling.
Development and evaluation of a variably saturated flow model in the global E3SM Land Model (ELM) version 1.0
Authors: Bisht Gautam , Riley William J. , Hammond Glenn E. , Lorenzetti David M.
Published: October 2018

Abstract. Improving global-scale model representations of near-surface soil moisture
and groundwater hydrology is important for accurately simulating terrestrial
processes and predicting climate change effects on water resources. Most
existing land surface models, including the default E3SM Land Model (ELMv0),
which we modify here, routinely employ different formulations for water
transport in the vadose and phreatic zones. Clark et al. (2015) identified a
variably saturated Richards equation flow model as an important capability
for improving simulation of coupled soil moisture and shallow groundwater
dynamics. In this work, we developed the Variably Saturated Flow Model (VSFM)
in ELMv1 to unify the treatment of soil hydrologic processes in the
unsaturated and saturated zones. VSFM was tested on three benchmark problems
and results were evaluated against observations and an existing benchmark
model (PFLOTRAN). The ELMv1-VSFM's subsurface drainage parameter,
fd, was calibrated to match an observationally
constrained and
spatially explicit global water table depth (WTD) product. Optimal
spatially explicit fd values were obtained for 79 % of global
1.9∘ × 2.5∘ grid cells, while the remaining 21 %
of global grid cells had predicted WTD deeper than the
observationally constrained estimate. Comparison with predictions using the
default fd value demonstrated that calibration significantly
improved predictions, primarily by allowing much deeper WTDs. Model
evaluation using the International Land Model Benchmarking package (ILAMB)
showed that improvements in WTD predictions did not degrade model skill for
any other metrics. We evaluated the computational performance of the VSFM
model and found that the model is about 30 % more expensive than the
default ELMv0 with an optimal processor layout. The modular software design
of VSFM not only provides flexibility to configure the model for a range of
problem setups but also allows for building the model independently of the ELM
code, thus enabling straightforward testing of the model's physics against
other models.
The aerosol-climate model ECHAM6.3-HAM2.3: Aerosol evaluation

Abstract. We introduce and evaluate the aerosol simulations with the global aerosol-climate model ECHAM6.3-HAM2.3, which is the aerosol component of the fully coupled aerosol-chemistry-climate model ECHAM-HAMMOZ. Both the host atmospheric climate model ECHAM6.3 and the aerosol model HAM2.3 were updated from previous versions. The updated version of the HAM aerosol model contains improved parameterizations of aerosol processes such as cloud activation, as well as updated emission fields for anthropogenic aerosol species and modifications in the online computation of sea salt and mineral dust aerosol emissions. Aerosol results from nudged and free running simulations for the 10-year period 2003 to 2012 are compared to various measurements of aerosol properties. While there are regional deviations between model and observations, the model performs well overall in terms of aerosol optical thickness, but may underestimate coarse mode aerosol concentrations to some extent, so that the modeled particles are smaller than indicated by the observations. Sulfate aerosol measurements in the US and Europe are reproduced well by the model, while carbonaceous aerosol species are biased low. Both mineral dust and sea salt aerosol concentrations are improved compared to previous versions of ECHAM-HAM. The evaluation of the simulated aerosol distributions serves as a basis for the suitability of the model for simulating aerosol-climate interactions in a changing climate.
A simple stress-based cliff-calving law
Authors: Schlemm Tanja , Levermann Anders
Published: October 2018

Abstract. Over large coastal regions in Greenland and Antarctica the ice sheet calves directly into the ocean. In contrast to ice-shelf calving, an increase in cliff calving directly contributes to sea-level rise and a monotonously increasing calving rate with ice thickeness can constitute a self-amplifying ice loss mechanism that may significantly alter sea-level projections both of Greenland and Antarctica. Here we seek to derive a minimalistic stress-based parameterization for cliff calving. To this end we compute the stress field for a glacier with a simplified two-dimensional geometry from the two-dimensional Stokes equation. First we assume a constant yield stress to derive the failure region at the glacier front from the stress field within the ice sheet. Secondly, we assume a constant response time of ice failure due to exceedance of the yield stress. With this strongly constraining but very simple set of assumption we propose a cliff-calving law where the calving rate follows a power-law dependence on the freeboard of the ice with exponents between 2 and 3 depending on the relative water depth at the calving front. The critical freeboard below which the ice front is stable decreases with increasing relative water depth of the calving front. For a dry water front it is, for example, 75m. The purpose of this study is not to provide a comprehensive calving law, but to derive a particularly simple equation with a transparent and minimalistic set of assumptions.
Local turbulence parameterization improves the Jensen wake model and its implementation for power optimization of an operating wind farm
Authors: Duc Thomas , Coupiac Olivier , Girard Nicolas , Giebel Gregor , Göçmen Tuhfe
Published: October 2018

Abstract. In this paper, a new calculation procedure to improve the accuracy of the Jensen wake model for operating wind farms is proposed. In this procedure the wake decay constant is updated locally at each wind turbine based on the turbulence intensity measurement provided by the nacelle anemometer. This procedure was tested against experimental data at onshore wind farm La Sole du Moulin Vieux (SMV) in France and the offshore wind farm Horns Rev-I in Denmark. Results indicate that the wake deficit at each wind turbine is described more accurately than when using the original model, reducing the error from 15–20 % to approximately 5 %. Furthermore, this new model properly calibrated for the SMV wind farm is then used for coordinated control purposes. Assuming an axial induction control strategy, and following a model predictive approach, new power settings leading to an increased overall power production of the farm are derived. Power gains found are in the order of 2.5 % for a two wind turbine case with close spacing and 1 to 1.5 % for a row of five wind turbines with a larger spacing. Finally, the uncertainty of the updated Jensen model is quantified considering the model inputs. When checked against the predicted power gain, the uncertainty of the model estimations is seen to be excessive, reaching approximately 4 %, which indicates the difficulty of field observations for such a gain. Nevertheless, the optimized settings are to be implemented during a field test campaign at SMV wind farm in scope of the national project SMARTEOLE.

Published: October 2018

Existe literatura extensa sobre los beneficios de la musicoterapia en la adolescencia, y más concretamente, en jóvenes con alguna dificultad social. Los objetivos de este estudio exploratorio fueron: a) Investigar si la participación en sesiones grupales de musicoterapia modificaba las relaciones existentes en los grupos globales; b) Identificar mejoras en las elecciones que realizaron entre el alumnado participante en la investigación, diferenciando a los alumnos del grupo control del grupo experimental. Participaron veinticuatro alumnos (17 hombres y 7 mujeres) de 3º y 4º de ESO del programa de Diversificación Curricular de un centro escolar en Madrid, divididos cada nivel en un grupo control y uno experimental. Los datos fueron recogidos a través de un sociograma. En cuanto a los resultados hubo cambios en relación a los sociogramas desde el pre al postest en sus relaciones en grupo. Los autores discuten sobre si las implicaciones del estudio podrían servir para mejorar las relaciones sociales entre adolescentes en los institutos, y si sería positivo la introducción de la musicoterapia en las escuelas como ayuda terapéutica. Tras el estudio se demuestra de manera estadísticamente significativa que las relaciones entre los participantes del grupo experimental se modifican.
Societal, Culture and Entrepreneurial Opportunities Exploitation of New Venture Activities: Mediating Role of Proactiveness
Authors: Xuhui Wang , Liu Jia , Pacho Frida
Published: October 2018

An unanswered question is concerned with the influence of culture of individualism, power distance and uncertainty avoidance in entrepreneurs’ opportunity exploitation of new venture activities in developing economies in the context of societal level. Based on the sample of 130 individual entrepreneurs in Tanzania, this paper analyses how culture of individualism, uncertainty avoidance and power distance influence entrepreneurial opportunity exploitation of new venture activities on societal level.  The results indicated that the culture of individualism contributes highly on entrepreneurs’ opportunity exploitation of new venture activities. The results of uncertainty avoidance imply that the greater the uncertainty avoidance, the less the entrepreneurs’ chance to exploit opportunities of new venture activities. The proactive behaviour that was used as a mediator variable also contributes to the relationship between individualism, uncertainty avoidance and entrepreneurs’ opportunity exploitation of new venture activities. The study has made a contribution to the developing countries literature by focusing on individual entrepreneurs on societal level.

Authors: Kulhavy David , Unger Daniel , Hung I-Kuai
Published: October 2018

A student led evaluation of desire paths (e.g., paths created by pedestrians on an open landscape) across the Stephen F. Austin State University (SFASU) campus was performed within a senior level spatial science course in order to create a method for mitigation of desire paths and for campus beautification.  Each desire path on campus was identified with the length of each path measured in the field and categorized by the condition of the path in order to assess and determine a necessary solution for each path identified. In addition, Pictometry® high spatial resolution digital imagery was used to determine if the categorization of the conditions of the desire paths, as well as the length of each desire path, could be identified and quantified without the need to measure each individual desire path in the field.  Students, within an interactive hands-on classroom environment, compared in-field desire path measurements with Pictometry® on-screen measurements to determine the effectiveness of remotely sensed Pictometry® imagery to identify and quantify desire path location and length respectfully.
The Impact of Technological Innovation on Corporate Performance: Evidence From the Communication and Cultural Industry in China
Authors: Wu Maoguo , Gu Nan
Published: October 2018

China’s communication and cultural industry is an emerging industry at the primary stage of its development. Nowadays, the public’s increasing demand for cultural products, coupled with the strong support from the state and the government for the communication and cultural industry, have provided huge room for the development of this industry. However, some listed companies in the communication and cultural industry have not kept up with the constantly changing market and have not invested heavily in R&D and technological innovation, resulting in widespread product homogeneity and poor corporate performance. This paper empirically tests the impact of technological innovation on corporate performance of 56 listed companies from 2007 to 2016 in the communication and cultural industry. Along with variables that proxy technological innovation, variables that proxy solvency, profitability, operational capability, development capability, social responsibility, and shareholder indicators are included in the regression as explanatory variables. Empirical results show that technological innovation has a positive impact on the corporate performance of listed companies in the communication and cultural industry.

Authors: Kueh Jerome , Wei Yong Sze
Published: October 2018

This study intends to investigate the validity of the foreign direct investment, FDI-led-growth hypothesis in Malaysia in this era. Autoregressive Distributed Lag (ARDL) bounds test approach is adopted to examine the impact of FDI inflow towards growth of Malaysia based on annually data from 1980 to 2016. Empirical results indicate that FDI inflow has significant positive impact on economic growth. This implies that FDI inflow remain important tool for stimulating economic growth of Malaysia. In addition, there is a negative impact of FDI inflow on economic growth during the 1997 Asian Financial crisis and positive impact during the 2008 Global Financial crisis. In terms of policy recommendation, the policy makers should continue to develop strategies to further attract FDI that will contribute to increasing the productivity in the country.
Impact of Internal Control System Structures According to (COSO) Model on the Operational Performance of Construction Companies in the Gaza Strip: An Empirical Study
Authors: Nashwan Iskandar M.
Published: October 2018

The construction sector is considered one of the most important sectors that support the economic development in any country as it helps in the development of the infrastructure, and affects the development of other sectors.

The study's main objective was to identify the impact of the internal control systems according to the (COSO) model with its elements (control environment, risk assessment, control activities, information and communication, monitoring and follow up) on the operational performance of construction companies in the Gaza Strip. Moreover, the current study aimed to examine the extent to which construction companies in the Gaza Strip comply with the internal control system structures according to the model with its elements.

In order to achieve the objectives of the study, it was implemented on (46) construction companies that operate efficiently and effectively in this sector and have organized financial and administrative systems governing their work. Therefore, the researcher designed a questionnaire for the study, which consisted of (49) paragraphs as a tool to collect required data, and was distributed to the sample of the study consisting of (460) individuals as (10) questionnaires were given to each company and retrieved (415) questionnaire valid for analysis (90.2%).The researcher also used the descriptive analytical method.

After analyzing the results, the study found that there is a great commitment of constriction companies  to the internal control structures of (COSO) model and there is a statistically significant positive effect for each of the elements of the model on the operational performance. Furthermore, the current study recommends that construction companies need to strengthen internal control systems that are efficient and effective by allowing the structures of their control systems to depend on the elements of the (COSO) model. Also it recommends researchers to conduct further studies on other sectors such as services , trade and industry.
Aircraft Wet Leases: Accounting Dissonance with Competitive Strategy and Travelers’ Perspectives
Authors: Bellandi Francesco
Published: October 2018

Under IFRS 16 and Topic 842 a lessee’s right to control the use an aircraft in a wet lease is an asset. On the other hand, contract analysis sees a wet lease as an opportunistic, external, temporary, competitive tool for flight flexibility and tactic cost advantage. Finally, travelers may be worried of safety and service quality or disruption in a wet lease, as the flight is not operated by their airline. This article addresses the accounting for aircraft wet leases as an exemplar case of a lease with substantial services, to discover that there is dissonance between the economic views behind accounting, business model and competitive strategy, and user service perspective.

After a thorough analysis of IFRS 16 and Topic 842 applied to wet leases for the first time in a public study, a review of disclosures in financial statements of 59 sampled airlines confirms a clear contrast between the competitive analysis, traveler’s perspective and the accounting view. Such a dystonia is supposed to reflect the view of investors and creditors, which the IASB’s and FASB’s Conceptual Frameworks denote as primary users of financial statements, as opposed to other members of the public, including customers. This results in a failure to give enough space to the indirect effects of such alternative views on customers’ demand and revenue, hence company’s prospects for future net cash inflows, which according to the Conceptual Framework is the main driver of investors and creditors decision making.

Highlights

Contract analysis is provided on wet leases as a business model competitive tool.

Analysis under IFRS 16 and Topic 842 and IAS 17/IFRIC 4 and Topic 840 is provided.

Above views are compared with travelers’ concerns about safety and service quality.

Airline financial statements disclosures on these three views are analyzed.

Views are traced to primary versus other users’ conflict in the Conceptual Framework.

Whether Asia is exposed to nuclear conflict
Authors: Zarychta Stanisław
Published: October 2018

The analysis of the political-military situation in South-east Asia shows that it is a hot
spot area which, in the future, might be a place of nuclear conflict. Disputes over natural
resources, the petroleum and natural gas of the South China Sea, may make it a global hot
spot. The main contenders who want to play the dominant role in the Asia and the Pacific
Ocean area are the United States and China.

Territorial disputes can also start a future war. Kashmir, which remains the source of
ceaseless tensions between India and Pakistan, can provide an example. Conflicts have
already consumed thousands of victims and repeatedly put the feuding sides on the edge of
the nuclear war.

Osteoarthritis (OA) is a type of degenerative joint disease where the balance between the degradation and the regeneration of articular cartilage is impaired, which leads to its progressive loss. This disease is the most common chronic musculoskeletal disease that leads to premature motor disability. Risk factors for developing OA include age, obesity, sex, past traumas and arthritis, genetic factors, diet and ethnicity. Typical OA symptoms are arthralgia, restriction of movement, cracking and secondary inflammatory lesions. In recent years, the underlying causes of this disease include chondrocyte death by apoptosis, necrosis or combinations of these types of cell death. Apoptosis, called programmed cell death, has clear morphological features, and is a highly regulated process. Apoptosis is involved in maintaining homeostasis; however, its severity is observed in many pathological conditions. Articular cartilage chondrocyte death by apoptosis disrupts the proper maintenance of cartilage structure by reducing cell density. Chondrocyte apoptosis causes mechanical damage, manifested by increased synthesis of free oxygen radicals and disturbance of the integrity of the extracellular matrix. An increasing amount of reports regarding the potential pharmacological substances that have been used as inhibitors of apoptosis have improved the quality of life in OA patients. This article
presents the current state of knowledge on apoptosis and apoptotic death of chondrocytes
in the course of osteoarthritis.

Published: October 2018

Background: Currently, there is a lack of validation studies available in the literature for the determination of ergocalciferol, especially for those using a direct extraction technique. The current official methodologies for the quantification of ergocalciferol require saponification, liquid−liquid extraction, or both, thus requiring experienced technicians and specialized reflux equipment. This work provides a method that is more easily accessible to laboratories without these resources while still achieving the robustness needed for a successful validation of low levels of ergocalciferol in complex matrixes. Objective: A single-laboratory validation study was conducted for a rapid quantification method of ergocalciferol in protein drink powders and tablets. Methods: The method uses an LC-MS/MS with multimode source utilizing atmospheric pressure chemical ionization positive ionization mode. For both protein drink powders and tablets, the procedure consisted of a liquid extraction step using dimethyl sulfoxide and methanol. Isotopically labeled ergocalciferol was used as an internal standard to correct for signal depression caused by matrix interference. Results: This LC-MS/MS method was found to be accurate, precise, linear (from 0.01 to 0.3 μg/mL), rugged, and suitable for protein drink powders and tablets. Conclusions: The method was validated and is suitable for accurate quantification of ergocalciferol in tablet and protein powder products. Highlights: This work provides a validated method for accurate quantification of ergocalciferol in complex matrixes using a direct extraction technique. This may benefit quality control laboratories in the food and nutraceutical industries, where simple and efficient methodology is key to optimal functioning.

Published: October 2018

Background: The green tea scraps are the waste materials during the process of green tea production, and it is significant to extractvaluable tea polyphenols (TP) for reuse. Objective: The objective of this study was to extract valuable TP from green tea scraps, and the extraction conditions were optimized to obtain maximum yield of TP. Methods: The TPwere extracted by supercritical carbon dioxide (SC-CO2) with 65% (v/v) aqueous ethanol solution as cosolvent. The content of TP was determinedwith the Folin-Ciocalteu method. The key factors ofthe extraction process, including temperature (313.15–323.15 K), pressure (20–30 Mpa), and amount of cosolvent (50–150 mL) were optimized by response surface methodology (RSM). Results: These key factors showed the extremely complex effects on the extraction yield of TP. A second-order polynomial mathematical modelwasdeveloped for the response with high R-squared value (R2 = 0.9946) and used to predict the optimal conditions (i.e., temperature of 322.15 K, pressure of 23.60MPa, and amount of cosolvent of 150 mL). The verification experiments showed that the maximum yield ofTP was 23.07 ± 0.82% under the optimal conditions, which was in good agreement with the predicted value. Conclusions: TP can be successfully extracted from green tea scraps by SC-CO2, and RSM could be used to optimize the extraction process. Highlights: SC-CO2 extraction of TP from green tea scraps was developed. The operating conditions, including pressure, temperature, and amount of cosolvent, were optimized. RSM could successfully predict the optimal operating conditions.

In vitro embryo production (IVP) is a biotechnology characterized by recovery (OPU) and
maturation (IVM) of selected oocytes from previously chosen donors. Fertilization of mature
oocytes (IVF), culture (IVC) of the embryos produced for transfer (ET) in receptors or
cryopreservation of these embryos is then carried out. The cryopreservation techniques consist of
storing the biological material in liquid nitrogen. These techniques drive the cells to a state of
metabolic numbness, and therefore, the material remains stable for a longer time. Thus, it
guarantees that when reheated they will maintain their characteristics and be able to transfer,
obtaining a pregnancy rate similar to those of embryos transferred fresh. The demand for
premium meats and the dairy market are increasingly demanding, requiring greater efficiency in
production, a factor that has intensified the use of these biotechnologies for both beef cattle and
dairy farmers. Therefore, in vitro fertilization increases the production of females in dairy herds
and contributes to the expressive gain of productivity and guarantees the achievement of low cost
pregnancy in commercial cutting herds. Therefore, the PIV still acts in the herds combining greater
profitability, quality and productivity.

The objective of the techniques of conservation of anatomical pieces is to preserve the
morphology, consistency, color and flexibility of the same. Among the techniques currently used
are formaldehyde, glycerin and fill/corrosion, which were compared in the present study. Four
pieces were used in the evaluation of each technique. For formalinization, the lungs were washed,
dissected and fixed in 10% formalin. For the glycerination technique, the organs were fixed in 10%
formaldehyde, washed for 48 hours, and then dried in the shade. Sequentially, the organs were
submerged in hydrogen peroxide 10 and again dried in the shade. Then, they remained
submerged in absolute alcohol for two months, were removed, dried naturally, and submerged in
glycerin for 30 days. For the filling/corrosion technique the lungs were washed, then submerged in

alcohol for 24 hours. The trachea was cannulated for the fixation step, through the canula a
continuous air stream containing alcohol and formalin mixture was introduced into the bronchial
tree. Subsequently, the acrylic was inserted, the pieces were placed in the water for 24 hours, and
soon the corrosion was carried out with hydrochloric acid. The glycerolation technique proved to
be more advantageous when compared to formaldehyde, since it presents a low toxicity and
irritation index, which facilitated the management and study, besides requiring a low degree of
maintenance. However, for the visualization of the bronchial tree, the filling/corrosion technique
proved to be superior to the others, but this technique demands greater care during its handling
and storage.
