OBJECTIVE:
To determine the impact of a baby-led approach to complementary feeding on infant choking and gagging.

METHODS:
Randomized controlled trial in 206 healthy infants allocated to control (usual care) or Baby-Led Introduction to SolidS (BLISS; 8 contacts from antenatal to 9 months providing resources and support). BLISS is a form of baby-led weaning (ie, infants feed themselves all their food from the beginning of complementary feeding) modified to address concerns about choking risk. Frequencies of choking and gagging were collected by questionnaire (at 6, 7, 8, 9, 12 months) and daily calendar (at 6 and 8 months); 3-day weighed diet records measured exposure to foods posing a choking risk (at 7 and 12 months).

RESULTS:
A total of 35% of infants choked at least once between 6 and 8 months of age, and there were no significant group differences in the number of choking events at any time (all Ps &gt; .20). BLISS infants gagged more frequently at 6 months (relative risk [RR] 1.56; 95% confidence interval [CI], 1.13–2.17), but less frequently at 8 months (RR 0.60; 95% CI, 0.42–0.87), than control infants. At 7 and 12 months, 52% and 94% of infants were offered food posing a choking risk during the 3-day record, with no significant differences between groups (7 months: RR 1.12; 95% CI, 0.79–1.59; 12 months: RR 0.94; 95% CI, 0.83–1.07).

CONCLUSIONS:
Infants following a baby-led approach to feeding that includes advice on minimizing choking risk do not appear more likely to choke than infants following more traditional feeding practices. However, the large number of children in both groups offered foods that pose a choking risk is concerning.

AUTOCRÍTICA ACADÉMICA DESDE UNA EXPERIENCIA EN EL ÁMBITO DE LA EDUCACIÓN SOCIAL: Reflexión sobre una experiencia desde el PRÁCTICUM de Educación Social
Authors: García Consuelo Moreno 
Published: September 2016

La comunicación presenta una inquietud profesional desde la reflexión y experiencia académica propiciada por un largo periodo como Coordinadora del PRÁCTICUM de Educación Social y, desde ella, recoge la crítica, también la autocrítica al quehacer universitario en relación a las pautas asumidas implícita o explícitamente desde el área de la política y la empresa. Concretamente, se centra en los estudios de Grado de la Educación Social y, por el interés para el movimiento higienista, en la educación sexual. En la denominada educación sexual parece extenderse e imponerse una exhaustiva información que no tiene en cuenta los múltiples aspectos formativos de los que es susceptible. En este sentido, nos preguntamos, sobre la delimitación o diferencia entre de lo que se hace supuestamente para asumir la educación de preadolescentes y jóvenes, y los posibles abismos a los que los acercamos al no tener en cuenta los valores como el respeto a uno mismo y al otro, el amor responsable etc.

Published: September 2016

The purpose of the research is to determine the means of development of speed-strength abilities manifesting in jump-offs in jumping exercises in classes with the 10th graders in order to improve the compliance with the standards of physical preparedness.
Materials and methods. Analysis and collation of scientific and methodological literature, special preparedness testing, methods of mathematical statistics. The participants in the experiment were eight 10th-grade boys who turned fifteen or sixteen at the time of the experiment.
Research results. During the experiment, we used the following tests: standing long jump, 30‑meter race from the standing start, standing triple jump. We suggested that the pupils perform special exercises: jumping on two legs and pulling up bent legs to the chest, repeated jumps on two legs over obstacles, jumping on two legs over the gymnastic bench while moving along the bench, jumping off a 60-70-cm height landing in half-squat, jumping off a 30-40-cm height onto two legs followed by a jump over obstacles (3-4 low barriers).
Conclusions. When performing jumping exercises, it is necessary to create conditions for the reactive-ballistic type of muscle contractions. Experimental exercises were selected by the criteria of “the dynamic compliance principle” to correspond, fully or partly, to the nature of motor activity: motor structure, jump-off biodynamics, muscle tension regime, peculiarities of manifestation of speed-strength abilities.

<p style="text-align: justify;">La composition colloïdale des moûts, c'est-à-dire les macromolécules solubles et les « bourbes fines », joue un rôle déterminant sur le développement et le terme de la fermentation alcoolique en vinification en blanc sec. La fixation des acides gras par les « bourbes fines » permet l'interprétation partielle du phénomène.

<p style="text-align: justify;">Le « Tsipouro » est une eau-de-vie de marc de raisins produite dans de nombreuses zones vinicoles de Grèce; elle est le précurseur de l'ouzo, anisette mondialement connue. Les auteurs étudient la composition de dix·huit échantillons de Tsipouro produit dans la région de Naoussa. Bien qu'il s'agisse d'une eau-de-vie de marc de raisins, les constituants favorables à la qualité se trouvent en quantités relativement importantes, tandis que les éléments indésirables ne dépassent pas les seuils acceptables et sont voisins de ceux rencontrés dans les eaux-de-vie de vins.</p><p style="text-align: justify;">+++</p><p style="text-align: justify;">« Tsipouro » is a spirit produced in several greek viticultural zones from grape pomace.

<p style="text-align: justify;">This work constitute a first approximation to study the relation between the value of the titrable acidit y at different pH and the colour intensity of wines. The organic acids from wines treated with NaOH are weak acids, for this reason the neutralisation with a strong alkali solution, it should give pH values greater than 7. We have studied a new parameter based on the difference between pH 8.2 (stablised by the Association of Official Analytical Chemists) and pH 7.0 (stablised by the Office International de la Vigne et du Vin). the mentioned parameter (AT<sub>8,2</sub>-AT<sub>7,0</sub>) has been used to find a possible differentiation between wines according to colour. Eighty eighth wines (white, red and rose) belonging to the three district making up the « Vinos of Madrid» Origin were analysed. The values of this new parameter are similar for white and rose wines but considerably differences were observed for the red type. A linear correlation was obtained between the <span>AT</span><sub>8,2</sub><span>-AT</span><sub>7,0 </sub>parameter and the colour intensity from red wines. Discriminant analysis were applied to this parameter in order to classify the wines according to their colour. A correct classification of 71.43 p. cent was obtained for the three different types of red wines.</p>

<p style="text-align: justify;"><strong>Aims</strong>: The present paper is focused on wild and feral grapevines from the Ega River gallery forest (Alder grove), one of the most important tributaries of the Ebro River. Since this area was preliminary prospected in 1995, it was our intention to assess the evolution of the ecosystem during this time.</p><p style="text-align: justify;"><strong>Methods and results</strong>: Ampelographic description of wild grapevines shows that all male plants had flowers with fully developed stamens and no gynoecium. No hermaphrodite individuals were detected. No virus infection and symptoms caused by Phylloxera on roots were detected. The Erineum strain of <em>Colomerus vitis</em> constitutes the main phytophagous arthropod. Damages caused by powdery and downy mildew were not lethal for the vines. Around 73% of the wild grapevine individuals found in 1995 had disappeared due to human impacts. The number of rootstocks and producer hybrids (French hybrids) had increased in this period by about 30%. Microvinification of wild berries yielded a wine with very high color intensity and total polyphenol index with a low pH.</p><p style="text-align: justify;"><strong>Conclusion</strong>: The wild grapevine population described has suffered a dramatic regression in the 20-year period between prospections, together with a significant increase of feral accessions thus endangering the endurance of the ecosystem and remaining wild grapevine.</p><p style="text-align: justify;"><strong>Significance and impact of the study </strong>: Wild grapevines are a valuable genetic resource for the genetic improvement of cultivated vines. However, our study shows that human impacts and increasing pressure of feral accessions are threatening wild grapevine populations.</p>

The highest concentrations of total anthocyanins and flavonols corresponded to the Gros noir variety. The results of the present study also indicate that the grape skin extracts of these Algerian cultivars can be used as easily accessible source of natural antioxidants. </p><strong>Significance and impact of the study</strong>: To the best of our knowledge, this is the first report on the identification of different anthocyanins and flavonols in berry skin from some red grape varieties largely cultivated in this region of Algeria.
Design of Autonomous Inflow Control Device Completions in Heavy Oil for Complex Reservoir Structures
Authors: Thornton Kim 
Published: September 2016

Abstract
Understanding reservoir structures is necessary when using autonomous inflow control devices (AICDs). Without a sound knowledge of nearby structures or manmade elements, such as injectors, production from heavy oil applications or any advanced completion may fall short of operator expectations. This paper provides several field examples to help illustrate the importance of understanding reservoir structures when using AICDs.
The approach of this study is based on using a near wellbore (NWB) hydraulic simulator coupled with a reservoir simulator to capture holistically the completion/reservoir effects and interaction. With this approach, the production of unwanted fluids is delayed. When unwanted fluids do eventually break through, the AICD can greatly reduce the negative effects of the unwanted fluids on well production. Usually, the unwanted fluids are water and/or gas. Unwanted water is typically (but not limited to) coning or fingering from bottom or edge water drive or from nearby injectors. Gas is coned or fingered downward from the gas cap.
Results show that, without understanding the structure and nearby anomalies of the reservoir, operators utilizing ICDs or AICDs can exacerbate the production of unwanted fluids. Field examples are derived primarily from heavy oil well completions designed for multiple operators in Columbia, Ecuador, Argentina, Brazil, Mexico, Alaska, and Canada over the last eight year period. Typically, completion design must change as more information is gathered about the reservoir. Structural maps are often difficult to obtain, however importing the reservoir model into the design reservoir simulator model adds value. However, the field simulator grid blocks can be too large, creating a lack of definition along the horizontal well, and log data may not be included. This paper presents some simple methodologies in generating the most effective design possible from provided data.
Establishing clear communication, gathering as much data as possible (including structural maps), and using proper models and simulators are key to optimizing advanced completion designs, particularly when utilizing AICDs in heavy oil.
Investigation of Post-Breakthrough Heavy Oil Recovery by Water and Chemical Additives Using Hele-Shaw Cell
Authors: Voroniak A.. , Bryan J. L. , Taheri S.. , Hejazi H.. , Kantzas A.. 
Published: September 2016

Abstract
There has been a large number of laboratory tests run in the past, looking at recovery of heavy oil by chemical flooding (polymer, surfactant and SP or ASP systems). These tests have all shown a potential for significant incremental oil recovery from chemical injection compared to water alone. The higher oil recovery was generally achieved under high pressure gradients that were generated during chemical injection. As such, the mechanism proposed in all of these studies is that of water channel blockage and improved sweep from chemical injection. In actual reservoir applications of chemical flooding, the impact of these water pathway blockages may be much less important than what is observed in the linear laboratory scale tests, so the actual mechanisms of chemical flooding in real systems may not be properly represented.
In this project, an experimental investigation is performed using a 2D visual Hele-Shaw cell, to visualize production mechanisms during the chemical flooding process. The 2D nature of the system allows for an understanding of whether chemicals sweep incremental oil from along the same channels as the pre-formed water or if new displacement channels are formed. The flow of a fluid in such models also represents flow without any pore-scale trapping, so observations can be made regarding whether trapping and fluid re-diversion are the only ways that these chemicals can yield improved oil recovery, or if simple alteration of the mobility ratio without additional trapping will already lead to incremental oil.
A Calculation Model for Steam Property Variation Along Wellbore Trajectory in SAGD Processes
Authors: Ju Ning , Zhao Gang 
Published: September 2016

Abstract
Steam properties such as steam pressure and steam quality are critical parameters to form integrated steam chamber and control steam consumption cost during SAGD process. However, steam property variation along steam injection well was not well understood yet. In this paper, a model describing steam flow behavior in steam injection wellbore was built and solved; accordingly steam property variation along steam injection wellbore can be calculated. In our model, both vertical and horizontal wellbores were further divided into several segments. Mass, momentum and energy balance equations have been applied to steam flow inside each segment. During the derivation of these equations, a void fraction correlation that is based on flow-pattern-independent drift-flux model was applied to describe steam flow in a non-uniform manner.
This model was validated by several sets of published field data and a series of general cases were studied to investigate the steam property variation inside wellbore. The computational results indicated that steam property distribution along vertical and horizontal wellbore portions have similar characteristics: steam pressure and steam quality tend to decrease along with wellbore trajectory in both vertical and horizontal wellbore portions during SAGD process; With the increase of steam injection pressure, steam quality decreases faster; with the increase of steam quality during injection, steam pressure decreases faster; With the increase of steam injection rate, steam pressure decrease faster while steam quality decrease slower. For horizontal wellbore, the increase of reservoir permeability tends to slow down the steam pressure decrease but accelerates steam quality deterioration; the increase of oil viscosity tends to slow down the steam quality deterioration but accelerate steam pressure decrease. The results from this study show the effects of steam properties varying along wellbore trajectory under different steam injection conditions and can be used as a design guidance to optimize the steam injection practice in SAGD process.
State of the Art Review of the Steam Foam Process
Authors: Delamaide Eric , Cuenca Amandine , Chabert Max 
Published: September 2016

Abstract
Foam has been used to improve the efficiency of steam injection since the late 1970s and the process has been applied successfully in several fields in particular in California but interest sagged at the end of the 1990s due to low oil prices and little activity took place for several years. The topic has however become more popular in the recent years due to higher oil prices. Foam is generated by the introduction of surfactant along with the steam into the reservoir and reduces its mobility, thus improving the sweep efficiency and reducing heat losses.
There has been no review of the process since the classical work by Hirasaki (Hirasaki 1989) and this paper proposes to remedy the situation and present a state of the art of the process.
The paper will revisit the field tests from the 1980 and then focus on the recent developments in the laboratory where researchers are attempting to develop new workflows and improved surfactant formulations for better performances; in the field with some recent pilot tests; and in terms of reservoir simulations.
This paper will allow engineers to get a complete and up to date understanding of the characteristics and limitations of the process and some guidance as to whether foam could help improve the performances of their steam injection projects.
