Authors: Martín Martínez Sandra Gisela
Published: December 2016

En este artículo se presenta una investigación cualitativa enfocada en establecer y caracterizar las relaciones y tensiones emergentes entre las pruebas Saber de Lenguaje (tercer y quinto grado) y las prácticas evaluativas de los profesores de básica primaria, valiéndose de la aplicación de un cuestionario mixto a los profesores de dicho nivel de educación en un colegio distrital, así como de una entrevista semiestructurada a cuatro expertos. Las categorías evaluación y competencia comunicativa guían la construcción del marco teórico, además de ser fundamentales para analizar la información a través de las dimensiones de la crítica educativa propuesta por Eisner en su obra El ojo ilustrado (1998). Al finalizar, en las conclusiones, la evaluación se plantea como un recurso de aprendizaje, con lo que se resalta la importancia que tiene ampliar la reflexión pedagógica acerca del uso de las pruebas y sus resultados en el país.
La escritura extensiva. La enseñanza de la expresión escrita en secundaria
Authors: Cassany Comas Daniel
Published: December 2016

Siguiendo la distinción entre lectura intensiva y extensiva, presentamos las tareas extensivas de expresión escrita para fomentar objetivos de aprendizaje como: 1) acercar la escritura a la vida personal del aprendiz; 2) practicar las funciones epistémica y comunicativa del lenguaje; 3) ceder al aprendiz toda la responsabilidad del acto creativo; 4) facilitar el desarrollo de los procesos cognitivos, y 5) generar hábitos sostenidos de producción escrita en variedad de situaciones. Por ello, las tareas extensivas de escritura producen escritos extensos, duran un periodo de tiempo largo, son autodirigidas por el aprendiz-autor, tratan temas interdisciplinarios y no forman parte del libro de texto. Dichas tareas difieren notablemente de los ejercicios escritos más frecuentes en el aula, dirigidos por el docente, con textos breves, funciones ejecutivas o instrumentales y una corrección centrada en la ortografía y la gramática. Proponemos varios instrumentos didácticos para fomentar este tipo de tareas: carpeta o portafolios (para guardar borradores, correcciones y versiones finales de cada texto), formatos (como diarios de lectura, apuntes de clase o protocolos de laboratorio) y contextos (tareas comunicativas del día a día). También argumentamos a favor de algunos parámetros básicos de las tareas extensivas, como la extensión del texto, el uso de varias sesiones de trabajo para la producción, la práctica de los procesos y subprocesos de composición o el uso de la revisión entre iguales, en parejas o equipos.
Recursos educativos abiertos, artefactos culturales, concepciones de los profesores de física para ingeniería: análisis de dos estudios de caso
Authors: Suárez Oscar Jardey
Published: December 2016

Esta investigación trata de responder preguntas como: ¿cuáles son las concepciones de los profesores de física, que trabajan en la Facultad de Ingeniería, sobre el uso de los recursos educativos abiertos (REA)? Este artículo se focaliza en develar las concepciones de los profesores de física que trabajan en la Facultad de Ingeniería en relación con los REA. Metodológicamente el proyecto tiene un componente cuantitativo y uno cualitativo. Este artículo es resultado de una fase cualitativa e interpretativa a partir de entrevistas extensas a profesores activos que regentan asignaturas de física en las carreras de ingeniería en instituciones de educación superior de carácter público o privado. Las entrevistas se desarrollaron a partir de situaciones elicitadoras que emergen de las categorías que surgieron de la revisión bibliográfica (artefacto cultural, ambiente de aprendizaje, sociocientífico, técnico y tecnológico). La interpretación de las entrevistas apunta a que hay concepciones en la realidad del laboratorio y su relación con los modelos, que hacen considerar que ésta puede distar de los modelos cuando los experimentos se tratan a través de simulaciones (las que pueden ser engañosas). Las conclusiones señalan que la matemática es la mediación más importante en la construcción y reconstrucción de modelos físicos, aunque no de forma unánime; se infiere que se pueden incorporar los REA como elementos complementarios de mediación posibilitando un espectro de opciones didácticas en la enseñanza de la física.

Authors: Escobar Figueroa Diego , Roa Guerrero Edgar
Published: December 2016

El manejo adecuado de frutas se ha convertido en una de las actividades económicas más importantes en la agricultura colombiana [1]. A la fecha, la identificación del estado de maduración de frutas se realiza manualmente [2], presentando variabilidad por la subjetividad producida debido a la fatiga ocular del experto. El propósito de esta investigación fue desarrollar una herramienta computacional para la identificación del estado de maduración de granadillas a partir del reconocimiento de imágenes. El área en píxeles de las imágenes perteneciente a la fruta fue extraída mediante la técnica de Otsu usando librerías de OpenCv en Python. Finalmente, la tarea de clasificación se realizó a través del análisis de agrupamiento, en el cual fueron asignados 110 puntos RGB pertenecientes a cada estado de maduración de la granadilla. Los resultados obtenidos muestran 92,6% de aciertos en la identificación del estado de maduración, a partir de un conjunto de 90 imágenes obtenidas de 90 frutas en diferentes estados de maduración, en comparación con el análisis manual acorde a lo establecido por la Norma técnica colombiana NTC 4101.

Authors: Lozano Mahecha Paula Andrea , Guerrero Caicedo Brandom Armando , Gordillo Ochoa Wilson Daniel
Published: December 2016

En una sociedad digitalizada que presenta cambios acelerados a causa del uso masivo de las TIC, se demandan estudiantes competentes, creativos, que posean conocimientos en tales campos, a pesar de que se considera que es complejo de aprender. Estos cambios se reflejan en todos los campos de la sociedad, no obstante, se subestiman en la educación rural donde la brecha digital es más sentida cada día. Ante la cantidad de herramientas tecnológicas que pueden integrarse al currículo para potencializar los procesos de enseñanza y aprendizaje, se decide implementar contenidos didácticos que, colectivamente con estas herramientas, para el caso Scratch y Makey Makey, fomenten habilidades del pensamiento de orden superior, y hacerlo entonces en la ruralidad con niños de grado cuarto y quinto demostrando que la tecnología debe ponerse al alcance de todos en aras de una inclusión digital sin distinciones, visionando el futuro del mundo rural de la mano del cambio tecnológico.

Examination of the leisure satisfaction levels of individuals partaking in recreational activities
Authors: Şahin Süleyman
Published: December 2016

The objective of this study is to examine the opinions of the individuals partaking in recreational activities on their leisure satisfaction levels in consideration of different variables. A total of 220 public employees, 150 (68.2%) of whom were "Male" and 70 (31.8%) of whom were "Female" selected by purposeful sampling method participated in the study voluntarily to this end. Screening model was utilized in the research. The sample of the study comprised the public employees of Avcılar district municipality of Istanbul province. In addition to the personal information form created through the researcher, "Leisure Satisfaction Scale" developed by Beard and Ragheb (1980) and adapted to Turkish through Karlı et al. (2008) was employed as data collection tool in the research. Percent (%) and frequency (f) methods were utilized for determining the distribution of personal information of participants while the Shapiro–Wilk test of normality was conducted with an eye to determine if the data had normal distribution and subsequently Mann -Whitney U-test and Kruskal-Wallis test were applied to determine the significant differences after it was understood that the data were appropriate for non-parametric test conditions. Male participants had a higher score than female participants in the "Psychological" and "Education" subscales of the leisure satisfaction scale in terms of gender. The scores achieved through participants aged 40 years and over are higher the scores of participants in other age groups, in the "Relaxation" subscale of the leisure satisfaction scale in terms of age. No significant difference was found in the subscales of the leisure satisfaction scale according to the monthly income variable. As a result, it was concluded that gender and age were significant factors in leisure satisfaction levels while monthly income was not a significant factor.

It is known that there is exactly one such invariant linear form up to multiplication by scalars, and an explicit linear form is given by integrating Whittaker functions over the F-points of the mirabolic subgroup when π is unitary and generic. In this paper, we prove that the essential vector of [14] is a test vector for this standard distinguishing linear form and that the value of this form at the essential vector is a local L-value. As an application we determine the value of a certain proportionality constant between two explicit distinguishing linear forms. We then extend all our results to the non-unitary generic case.
Determination of aquifer parameters using geoelectrical sounding and pumping test data in Khanewal District, Pakistan
Authors: Akhter Gulraiz , Hasan M.
Published: December 2016

In order to determine the groundwater resources and potentials of the Khanewal District of Pakistan, a geophysical method in combination with pumping test data were used. An analytical relationship between the aquifer parameters interpreted from surface geoelectrical method and pumping test was established in order to estimate aquifer parameters from surface measurements where no pumping tests exist. For the said purpose, 48 geoelectric investigations were carried out using Schlumberger vertical electrical sounding (VES). Seven of the soundings were conducted where pumping tests had been carried out at borehole sites. The vertical electrical sounding stations were interpreted, and resistivities and thickness parameters were calculated. The values of transmissivity and hydraulic conductivity were calculated using the Dar Zarrouk parameter. Transmissivity values obtained from pumping test data and the VES method range between 954 – 4263 m

Published: December 2016

This manuscript describes the analysis of temperature and the distribution of natural convection flow of three different cookware materials composed of stainless steel, aluminum and enameled iron, when heating olive oil. A Computational Fluid Dynamic (CFD) software, called COMSOL Multiphysics©, has been used to analyze the heat transfer process for this study. In addition, a thermographic camera and a particle tracer were employed to compare the measurements of temperature, heat transfer and flow velocity, obtained from the CFD analysis. The results demonstrated that the enameled iron was the best choice of cookware material for induction stoves, as with the increment of oil temperature, this material had the biggest contrails and oil velocity convection flow in the center of the cookware.
The Stress-Relaxation Behavior of Rice as a Function of Time, Moisture and Temperature
Authors: Wang Pan , Wang Li-jun , Li Dong , Huang Zhi-gang , Adhikari Benu , Chen Xiao Dong
Published: December 2016

Stress-relaxation behavior of single rice kernel was studied using a dynamic mechanical analyzer (DMA) in compression mode. The relaxation modulus was measured in a moisture content range of 12–30 % on dry basis (d.b.) and a temperature range of 25–80°C. A constant stain value of 1 % (within the linear viscoelastic range) was selected during the stress-relaxation tests. The relaxation modulus was found to decrease as the temperature and moisture increased. A master curve of relaxation modulus as a function of temperature and moisture content was generated using the time–moisture–temperature superposition principle. Results showed that the generalized Maxwell model satisfactorily fitted the experimental data of the stress-relaxation behavior and the master curve of relaxation modulus (R
2> 0.997). By shifting the temperature curves horizontally, the activation energy of the stress relaxation was obtained which significantly decreased with increase in the moisture content.

New bounds for the minimum eigenvalue of M-matrices
Authors: Wang Feng , Sun Deshu
Published: December 2016

Some new bounds for the minimum eigenvalue of M-matrices are obtained. These inequalities improve existing results, and the estimating formulas are easier to calculate since they only depend on the entries of matrices. Finally, some examples are also given to show that the bounds are better than some previous results.

In the post-2016 election period, nonprofit institutions, particularly charities, might react to new challenges in more than a defensive way. Opportunities include much greater self-examination of ways to enhance the effectiveness of their own actions and making trade-offs in the forthcoming tax and spending debates that stress exchanging less effective provisions for more effective ones.
Ultrafast Transient Absorption and Terahertz Spectroscopy as Tools to Probe Photoexcited States and Dynamics in Colloidal 2D Nanostructures
Authors: Lauth Jannika , Kinge Sachin , Siebbeles Laurens D.A.
Published: December 2016

Two-dimensional (2D) semiconductors hold high potential for the implementation of efficient ultrathin electronics (e.g. field-effect transistors, light emitting diodes and solar cell devices). In recent years, colloidal methods to synthesize ultrathin 2D materials have been developed that offer alternatives (like the production of non-layered 2D materials and upscaling) to mechanical exfoliation methods. By focusing on optoelectronic applications, it is important to characterize the nature and dynamics of photoexcited states in these materials. In this paper, we use ultrafast transient absorption (TA) and terahertz (THz) spectroscopy as optimal tools for such a characterization. We choose recently synthesized ultrathin colloidal 2D InSe nanosheets (inorganic layer thickness 0.8–1.7 nm; ≤5 nm including ligands) for discussing TA and THz spectroscopic studies and elucidate their charge carrier dynamics under photoexcitation with TA. THz spectroscopy is then used to extract contactless AC mobilities as high as 20±2 cm2/Vs in single InSe layers. The obtained results underpin the general applicability of TA and THz spectroscopy for characterizing photoexcited states in 2D semiconductors.
Species Richness and Birds Conservation Priority in Mount Rinjani Areas, Lombok
Authors: Hadiprayitno Gito , Mertha I Gde , Ilhamdi Moh. Liwa
Published: December 2016

Mount Rinjani area on the island of  Lombok is unique in bioecology. It provides habitats for many species of birds, especially birds of Wallacea. Several studies  on birds in this area have been done, but the conservation priority of these birds has not been determined. Based on this condition, the purpose of this research is to determine the priority of birds conservation in mount Rinjani areas. Exploration about the spesies of birds was started from Senaru Village to Segara Anak Lake. Abundance of each bird species was estimated using point count. Data analysis to determine the conservation priority used indicators that consist of endemicity, population status, species threatened and species management. The results showed that the birds species in mount Rinjani  areas are composed of 32 species belonging to 20 families. Bird species that have high abundance were Amandava amandava (15.94%), Zosterops Montanus (15.70%), and Parus major (11.32%), while Ptilinopus melanospila and Anthus novaeseelandiae were in low abundance (0.23%). Analysis birds conservation priority  in mount Rinjani areas indicates that Otus jolandae has the highest score (65) and should be the first priority for the conservation, while Philemon buceroides and Gallus varius with the same score (60) are the second priority.

REDESIGNING THE ASSIGNMENT OF INTERNAL AUDITORS BASED ON AUDITOR UTILITY
Authors: KARAÖZ BURCU
Published: December 2016

This study presents a novel model for assignment of internal auditors to branches of businesses. Previous studies have concerned with minimizing the cost but in this model, aim is maximizing auditor’s utility. For this purpose an integer programming model introduced. The objective is maximizing the auditors’ total utility. Each branch has different impact values for auditors, which indicate auditors’ utility level in terms of location, size and type of branches. Also to keep the balance of auditor’s working days and total gained impact values particular constraints are defined for the integer programming model. This implementation has 3 particular steps; first is quantification of the branches’ effects on the auditors. AHP method is used to define branches’ impact values. The second is simulating the durations of auditing process. To minimize the effect of abnormal situations, durations are simulated. Last step is to reach the rotation of auditors, total working days and the total utility of the auditor; the integer programming model is solved by Python-Gurobi Optimizer.

KÜRESEL EKONOMİK KRİZ SÜRECİNDE ADAY ÜLKELERİN MALİ PERFORMANSLARININ AVRUPA BİRLİĞİ’NE ÜYELİK KRİTERLERİNE UYUMU
Authors: Güngör Kamil
Published: December 2016

Avrupa Birliği mali disiplin ve sürdürülebilir bir ekonomik büyüme sağlamak için 1993’te Maastricht kriterlerini benimsedi. Maasrticht kriterleri Avrupa Birliğine üyelik için bir değil ama parasal disiplin için zorunludur. Ancak 2007 sonrası başlayan global kriz hem Avrupa Birliği’ne üye ülkeleri hem de aday ülkeleri derinden etkilemiştir. Avrupa Birliği, üye ülkelerin Maastricht kriterlerini tekrar sağlayabilmeleri için 2016’ya kadar devam edecek olan bir takvim belirlemiştir. Zira 2009 yılında etkisini gösteren küresel kriz, kamu açıklarını ve borç stoklarını önemli ölçüde artırmıştır. Bu nedenle, kriz sonrası dönemde bozulan mali dengelerin yeniden sağlanması ve benzer durumların tekrar yaşanmaması için Avrupa Birliği çeşitli önlemler almıştır. Müzakere süreci devam ettiği için Avrupa Birliğinin uygulamaları Türkiye'yi de ilgilendirmektedir. Bu çalışma Türkiye’nin ve diğer aday ülkelerin hazırlık durumunu analiz etmektedir.

Published: December 2016

The aging and the elderly are highly associated with limitation or dependency, with some loss of capacities and the gain of conditions or age-associated pathologies. Despite advances in preventive dentistry, edentulism and oral diseases are major public health issues in Portugal, mainly among the elderly. This study investigated the oral status and level of oral rehabilitation among Portuguese institutionalized elderly. The purpose of the study was to determine the prevalence of edentulism and assess the oral rehabilitation and oral/prosthetic hygiene habits in a sample of institutionalized elderly using a cross-sectional study in a sample of 118 institutionalized elderly. Data collection was performed by applying a questionnaire about oral health behaviors and through an intraoral observation in order to determine the oral status and verify the condition of the oral rehabilitation of each participant. The findings revealed that 78.6% have a number of decayed, missing and filled teeth more than 20, 58.8% presented total edentulism (with no natural teeth in the oral cavity) and 66.7% had a removable prosthesis. Only 44.1% practiced daily oral/prosthetic hygiene at least twice a day while 29.0% and 67.7% complained of toothache and difficulty in chewing respectively. The educational level of the elderly was associated with dental pain (p=0.012) and oral/prosthetic hygiene (p=0.034). A high prevalence of tooth loss was found in the sample studied and also the need to improve the removable prosthesis is fundamental. Improvement in oral health care and oral hygiene habits is essential to promote better oral health and quality of life among the institutionalized elderly.
Neuroprotective effects of herbal cocktail on cerebrovascular dysfunction in rats with induced hyperhomocysteinaemia
Authors: Algohary Ayman Mohammed , Ahmad-Farid Omar Abdel-Hamed , Abd-Elrazek Areeg Mohammed , Al-Baradie Raid Selem
Published: December 2016

Introduction: Hyperhomocysteinaemia (HHcy) is an established risk factor for cardiovascular, cerebrovascular, peripheral vascular diseases and neurodegenerative disease. The effect of this HHcy on vascular diseases could potentially cause vascular pathology features. Experimental studies have demonstrated that Hcy can be neurotoxic to brain, hippocampus area. 

Methods: The present study was conducted to compare the possible neuroprotective effects of different herbal cocktail in HHcy-induced rats’ brain cerebrovascular dysfunction model. Rats were divided into nine groups: Group I - Controls received the same volume of saline solution (0.5 mL/100 g of body weight). Group II served as HHcy and received homocysteine 0.03 μmol/g of b.w. daily for 30 days. Group III served as HHcy and received homocysteine 0.03 μmol/g of b.w. + Artemisia Judaica extract (AJ) (50 mg/kg per oral by oral feeding needle with tuberculin syringe) daily for 30 days. Group IV served as HHcy and received homocysteine 0.03 μmol/g of b.w.+ Panax ginseng extract (PG) (50 mg/kg per oral by oral feeding needle with tuberculin syringe) daily for 30 days. Group V served as HHcy and received homocysteine 0.03 μmol/g of b.w. + Polygonum multiflorum extract (PM) (400 mg/kg per oral by oral feeding needle with tuberculin syringe) daily for 30 days. Group VI served as HHcy and received homocysteine 0.03 μmol/g of b.w. + AJ + PG with the same dose of previous group daily for 30 days. Group VII served as HHcy and received homocysteine 0.03 μmol/g of b.w. + AJ + PM with the same dose of the previous group daily for 30 days. Group VIII served as HHcy and received homocysteine 0.03 μmol/g of b.w. + PG + PM with the same dose of the previous group daily for 30 days. Group IX served as HHcy and received homocysteine 0.03 μmol/g of b.w. + AJ + PG + PM with the same dose of previous group daily for 30 days. The hippocampus of brain samples was collected at the end of the experiment and measuring oxidative stress markers (CAT, SOD, MDA and NO), inflammatory mediators (IL-6 and BDNF), histopathological examination and comet assay.

Results: Revealed data showed that the homocysteine induces SOD, CAT depletion, and an increase in AChE, MDA, NO, IL-6, and BDNF. A mixture of PG and PM or the individual treatments showed an ameliorative response for all parameters. In general, oxidative stress parameters, inflammatory mediator, neurotrophic factor, pathological examination and comet were degenerate against HHcy but did not differ significantly compared to AJ group.

Conclusion: Better physiological and histological characteristics were in PG and PM and their combination groups compared with HHcy and ameliorated nearly the control group.

Published: December 2016

BACKGROUND:

Meningococcal conjugate vaccination is recommended in the United States. This study evaluates the safety of quadrivalent meningococcal conjugate vaccine in a cohort aged 11 to 21 years.

METHODS:

This cohort study with self-controlled case-series analysis was conducted at Kaiser Permanente Southern California. Individuals receiving MenACWY-CRM, a quadrivalent meningococcal conjugate vaccine, during September 30, 2011 to June 30, 2013, were included. Twenty-six prespecified events of interest (EOIs), including neurologic, rheumatologic, hematologic, endocrine, renal, pediatric, and pediatric infectious disease EOIs, were identified through electronic health records 1 year after vaccination. Of these, 16 were reviewed by case review committees. Specific risk and comparison windows after vaccination were predefined for each EOI. The relative incidence (RI) and 95% confidence intervals (CIs) were estimated through conditional Poisson regression models, adjusted for seasonality.

RESULTS:

This study included 48 899 vaccinated individuals. No cases were observed in the risk window for 14 of 26 EOIs. The RI for Bell’s palsy, a case review committee-reviewed EOI, was statistically significant (adjusted RI: 2.9, 95% CI: 1.1–7.5). Stratified analyses demonstrated an increased risk for Bell’s palsy in subjects receiving concomitant vaccines (RI = 5.0, 95% CI = 1.4–17.8), and no increased risk for those without concomitant vaccine (RI = 1.1, 95% CI = 0.2–5.5).

CONCLUSIONS:

We observed a temporal association between occurrence of Bell’s palsy and receipt of MenACWY-CRM concomitantly with other vaccines. The association needs further investigation as it could be due to chance, concomitant vaccination, or underlying medical history predisposing to Bell’s palsy.

Objective: This study aimed to evaluate the influences of surface roughness (SR) of denture base and liner materials on Candida albicans biofilm formation.Methods: Discs were fabricated using poly (methyl methacrylate) acrylic resin and poly(ethyl methacrylate) denture liner, according to manufacturers’ instructions. Both acrylic resin and relined discs were finished or finished + polished and the SR was measured. Discs were saliva-coated, and C. albicans biofilms were developed on such surfaces for 48 hours. Biofilms were evaluated for cell counts, metabolic activity, and structural characteristics. Data were analyzed by one-way ANOVA and Tukey tests using a significance level of 5%.Results: Finished acrylic resin and denture liner discs had higher SR compared to finished + polished discs (P<0.001). Finished + polished acrylic resin discs contained fewer cells compared to only finished discs (P<0.001). No metabolic activity differences were seen between biofilms formed on both groups (P>0.05). Bulky, thick and less rough biofilms were formed on only finished denture materials (P<0.05). Confocal images reveal increased presence of black spaces for biofilms developed on finished + polished discs. Conclusion: Reduced SR resulted in decreased C. albicans biofilm accumulation on both denture materials.

Objective: To evaluate the use of optic fiber and different pre-irradiation times (PIT) in phototherapy with LED for the root canal disinfection of bovine teeth infected in vitro with Enterococcus faecalis.Methodology: The teeth were incubated for 60 days and divided into six groups according to disinfection protocol: Group 1 – distilled water; Group 2 – 1 minute PIT and no optic fiber; Group 3 – 1 minute PIT and optic fiber; Group 4 – 5 minute PIT and no optic fiber; Group 5 – 5 minute PIT and optic fiber; Group 6 – 2% sodium hypochlorite. Microbiological test (CFUs counting) and scanning electron microscopy (SEM) were performed to evaluate the effectiveness of proposed treatments.Results: SEM analysis of canal wall, in the three thirds, revealed group 6 had the best results, whereas microbiological results revealed that group 6 had the best results. No differences in disinfection of root canals were found when optic fiber was used for photodynamic therapy. Conclusion: Photodynamic therapy should not be used alone in the disinfection of root canals, but it may be valuable as a complement for disinfection performed using different cleaning methods.

Objective: To evaluate the shear bond strength of orthodontic accessories bonded to a porcelain surface after storage in water.Methods: One-hundredand-twenty feldspathic porcelain discs were divided into 4 groups, according to the surface treatment: Group 1 – 37% phosphoric acid etching; Group 2 – 10% fluorhydric acid; Group 3 – 37% phosphoric acid and silane application; Group 4 – 10% fluorhydric acid and silane application. After the accessories were bonded, the sample was divided into two subgroups, according to the time interval of storage in distilled water: Control – 24 hours; and Test – 150 days. Shear bond strength was determined using a universal test machine, and failure type was verified by scanning electron microscopy.Results: In the test groups there was reduction in shear bond strength, particularly when silane was used. Test Groups 2 and 4 presented shear bond strength values within those proposed as adequate for orthodontic bonding. Groups 1 and 3  presented adhesive failures between porcelain and resin, whereas in Groups 2 and 4 cohesive failures in porcelain were recorded.Conclusion: Storage in water for 150 days decreased the bond strength at silanized interfaces. Fluorhydric acid etching generates adequate bond strength in wet conditions, however, increases the fracture rate in porcelain.

Authors: Glushkov O.
Published: December 2016

The publication presents data on the effect of polysaccharides as cryoprotectants on changes of the lipid fraction of quick-frozen semi-finished products during storage. Since the structure of minced systems is formed as a result of the destruction of the native structure of the meat and the formation of a new secondary structure, it is important to establish the effect of cryoprotectants on the key functional and technological properties of meat systems after freezing, and in the process of storage. Based on studies of the kinetics of the oxidation of fat and accumulation data on the accumulation of the primary and secondary products of oxidation inhibition of oxidative processes has been found.
