Authors: Upadhyay Hari Prasad , Sedain Prativa
Published: July 2019

Background: A social networking site is an online platform that allows users to create a public profile and interact with other users on the website. The emergence of Social Networking Sites has broadened the base of contact, interaction and communication among people living round the globe via internet. Millions of students are logging in to these social networking sites, everyday. That’s why many students have been blaming various social networking sites for their steady decrease in grade point averages and has affected their study time, poor grammar and wrong spellings when socializing on social media as well as diverting their attention from their studies. The objective of this research is to find the impact and perception of social networking sites on academic performance of medical students.

Methods: A descriptive cross-sectional study design conducted among 230 Medical students of MBBS, BPH, Pharmacy and BN Nursing’s students. A well-structured questionnaire was prepared and which were distributed among students using probability sampling technique (random number table).

Results: The response of 230 students was collected by using well structure questionnaire. The mean±SD of students age was 21.87±2.16 years. Majority of the students were in the age group 20-25 years. Majority of them were female by gender and Hindu by religion. They most commonly used social networking site was face book/messenger (48.7%) followed by YouTube (41.3%). The main aim of using these sites is to update with their family, friends and for entertainment. Nearly 60% students told that there are negative effects of using social networking sites. And only 15.6% students used these sites only for academic purpose.

Conclusions: This study revealed that majority of the students used mobile phone as a device and Wi-Fi in their place of residence. The overall perception of students towards social networking sites is positive. Excessive use of these sites decreases their academic performance which conclude that there is Negative relationship between the use of social networking sites and academic performance which in turn negatively affect their academic results.

Authors: Sapkota Ranjan , Sayami Prakash
Published: July 2019

Background: Thoracoscopic surgery has been increasingly used for a variety of indications. Posterior mediastinal tumors form an important component of a thoracic surgeon’s workload. This report represents a summary of our initial experience in thoracoscopic management of such tumors.

Methods: We retrospectively reviewed the clinical and operative data from records over the study period. We also describe our usual perioperative management and surgical techniques.

Results: A total of 11 patients, 8 being females, were operated during the period of 30 months. Seven were incidental findings, and chest pain was the commonest presentation in symptomatic patients. The mean age of the patients was 38.7 years; mean tumor diameter was 4.4 cm; eight had benign schwannoma, and no patient had a malignant tumor. Mean operative duration was 175.5 min; there were no conversions and no transfusion was required. Mean length of stay in the hospital was 5.6 days. There were no perioperative deaths or major complications. Three minor complications were recorded. Follow-up (4 to 18 months) was uneventful.

Conclusions: Thoracoscopic management of posterior mediastinal tumors is feasible and safe.

Authors: Rusakovskaya O. A. , Kostjuk G. P. , Golubev S. A. , Drykina L. L. , Galkina A. O.
Published: July 2019

The paper presents an overview of foreign research findings concerning parents with learning disabilities and their children. The extent of such parents in general population and among families, involved into court samples and child protection services, is presented. A review shows that parental competence is not directly related to IQ, but is mediated by additional risk factors, such as social isolation, parental stress, poverty, low socioeconomic status, poor health, poor parental childhood experience of abuse and neglect, that may be compensated by special social support. The problems of discrimination of parents with learning difficulties and necessity of their social support are discussed.

Authors: Tsidik L. I.
Published: July 2019

Psychodiagnostic measuring instruments created within the framework of the classical theory of tests are distinguished by the instability of all psychometric parameters. Therefore, there arose the need to use modern scientifically grounded approaches for designing techniques that lack these shortcomings. The purpose of the study: to carry out an analysis of the psychometric properties of the scale of social anxiety of the questionnaire of neurotic disorders. A total of 296 people were tested. The main statistical method of work is the metric Rush system. Results: the approval of the scale of social anxiety possess an adequate constructual validity, measures of difficulty points are in the range from -2 to +2 logits, the scale is one-dimensional, has a relatively balanced metric structure, the reliability index is 0.83, the scale is able to differentiate the three levels of expression of the construct.
A pilot study of interpersonal process group therapy for PTSD in Canadian Veterans
Authors: van Reekum Emma A. , Watt Margo C.
Published: July 2019

Introduction: The present pilot study was designed to explore interpersonal process (IP) group therapy for post-traumatic stress disorder (PTSD); a novel and relatively untested treatment approach for PTSD. IP groups seek to normalize patients’ symptoms and enhance functioning by creating a safe environment wherein participants can engage with others who share similar experiences and symptoms. Methods: Present IP groups met weekly for 12 weeks. Participants included 20 Canadian male Veterans and RCMP officers (10 per treatment group) with a primary diagnosis of PTSD. All participants had previously received first-line treatments for PTSD but continued to experience serious limitations in functioning. Key measures of interest (i.e., PTSD, negative affect, moral injury) were administered immediately pre- and post-intervention. Qualitative data was collected from a subset of participants ( n = 6). Results: Baseline scores revealed significantly elevated symptom levels compared to normative and clinical samples. Retention rate over the course of therapy was 100%, a rare and important finding in clinical research generally, and in the PTSD population more specifically. Qualitative feedback was consistently positive; feedback also suggested future potential improvements for the therapeutic intervention. There was a significant reduction in anxiety (specifically, physiological hyperarousal) pre- to post-intervention, with a partial eta squared ( n2 p) value of 0.26, indicating a large effect size. Discussion: Examination of individual scores showed that fully one-third of participants demonstrated a reliable improvement in both physiological anxiety and anxiety sensitivity (AS), both of which have been implicated in the exacerbation and maintenance of other PTSD symptoms. Results support a randomized controlled trial of group IP for PTSD.
A comparative analysis of medically released men and women from the Canadian Armed Forces
Authors: Serré Lynne
Published: July 2019

Introduction: Musculoskeletal (MSK) injuries and mental health (MH) disorders are the leading causes of medical attrition in the Canadian Armed Forces (CAF). Historically, medical attrition rates have been higher for women than men. In order to better understand the medical release trends of men and women, a descriptive analysis of the medical reasons for release was undertaken. Methods: Administrative data sources within the Department of National Defence were used to identify medically released personnel together with their primary medical diagnosis and demographic characteristics, including sex, age, and rank. The analysis included 5,180 Regular Force personnel medically released between April 1, 2014 and March 31, 2017. Results: While overall trends in the reasons for medical release were sometimes similar for men and women, statistically significant differences between the medical release reasons of men and women were found in several of the sub-groups considered. These sub-groups included non-commissioned members (NCMs), officers, Air personnel, and members who had not deployed in the 10 years prior to their release, as well as personnel in the earlier and later stages of their career. Discussion: An increased understanding of the differences between medically released men and women is important for the development of future injury and illness prevention strategies, which have the primary objective of improving the health and operational readiness of serving members, as well as a secondary objective of lowering medical attrition rates to improve overall retention in the CAF.
Delivering services to the families of Veterans of current conflicts: a rapid review of outcomes for Veterans
Authors: Oster Candice , Lawn Sharon , Waddell Elaine
Published: July 2019

Introduction: Military service affects the health and well-being of both Veterans and their family members, with increasing recognition of the need for support to be provided to Veterans’ families. In 2017 the Australian Department of Veterans’ Affairs commissioned a rapid review of the literature to explore whether the delivery of support services to families of contemporary Veterans results in better outcomes for the Veteran. Methods: A systematic search of the peer-reviewed literature resulted in the extraction of 30 articles, reduced to 29 following quality assessment. We then produced a narrative synthesis of the articles. Results: All of the studies were undertaken in the United States (US). The majority ( n = 20) focused on couples/family therapy, in particular, to address post-traumatic stress disorder (PTSD) in Veterans. Discussion: The studies overall reported significant psychological and relational benefit for Veterans when families are supported. However, the diversity of approaches suggests that currently, no one approach suits all family situations. More work is needed to develop interventions that address the broader psychosocial needs of families, such as work commitments and childcare needs, and to evaluate how these might benefit Veterans.
Group identity, diffi cult adjustment to civilian life, and suicidal ideation in Canadian Armed Forces Veterans: Life After Service Studies 2016

Published: July 2019

Introduction: Suicide risk is higher in Canadian Armed Forces (CAF) Veterans than the Canadian general population (CGP). Suicidality is understood to be caused by incompletely clarified, complex interacting combinations of multiple factors. One of the precipitating factors for suicide is thought to be the social identity challenges known to occur in major life transitions. Methods: The 2016 Life After Service Studies survey representatively sampled Regular Force Veterans stratified by two release groups: earlier in 1998 to August 2012 ( n = 1,575) and more recently in September 2012 to 2015 ( n = 1,180). The linked dataset included socioeconomic and military characteristics and well-being indicators in multiple domains. Weak group identity was indicated by weak sense of local community belonging and/or not feeling part of a group with shared attitudes and beliefs. Associations were evaluated with multiple logistic regression. Results: Suicidal ideation, weak community belonging, and perceived difficult adjustment to civilian life were more prevalent in Veterans soon after release (September 2012 to 2015) than in Veterans released earlier (1998 to August 2012). Suicidal ideation and weak community belonging were more prevalent in the Veterans than in the CGP. In the more recently released Veterans, weak group identity was endorsed by the majority with suicidal ideation (93.3%). In adjusted regression models, mental health problems had the strongest association with suicidal ideation (adjusted odds ratio [AOR] = 13.4–79.3); however, weak group identity was moderately strongly associated with both difficult adjustment (AOR = 2.4–4.1) and particularly suicidal ideation (AOR = 3.8–9.0), independently of mental health problems. Discussion: Weak group identity was associated with difficult adjustment to civilian life and suicidal ideation in CAF Regular Force Veterans within 3.6 years after military release. These findings indicate the importance in suicide prevention of attending to social identity during transition to post-military life.

Nghiên cứu này trình bày phương pháp dự báo khả năng chịu lực còn lại của cột bê tông cốt thép (BTCT) chịu nén lệch tâm phẳng có cốt thép dọc bị ăn mòn sử dụng phần mềm XTRACT 3.0.8. Ảnh hưởng của sự ăn mòn cốt thép được kể đến thông qua sự suy giảm cường độ đối với bê tông khi chịu nén, và sự suy giảm cường độ và độ dẻo đối với cốt thép khi chịu kéo và chịu nén. Phương pháp này được áp dụng trên một cột ngắn bằng bê tông cốt thép (BTCT) có tiết diện 600 × 600 mm, với hàm lượng cốt thép dọc là 1,64%, và tỷ lệ giữa chiều dày lớp bê tông bảo vệ và đường kính cốt dọc là 1,6. Trong thực tế, sự ăn mòn không diễn ra đồng đều trên tất cả các vị trí (bề mặt) của cấu kiện. Do đó, nghiên cứu này khảo sát sáu trường hợp ăn mòn cốt thép dọc tương ứng với các vị trí khác nhau để xây dựng các biểu đồ tương tác P-M. Những biểu đồ này chỉ ra rằng khả năng chịu lực còn lại của cột BTCT phụ thuộc vào mức độ ăn mòn cũng như vị trí ăn mòn của cốt thép dọc.

La importancia de las nuevas tecnologías en la democracia participativa. El caso de la Iniciativa Ciudadana Europea
Authors: Magalhães Silva Maria Manuela , Resende Alves Dora , João Ferreira Maria
Published: July 2019

Democratic participation still is the way forward for societies that seek permanent peace through the exercise of active citizenship. Since 2012, the European Citizens’ Initiative instrument has emerged in the process of drafting legislative acts of the European Union. One of the facets of this citizenship is to enable citizens to become involved in decision-making through participation in the exercise of legislative initiative. The Lisbon Treaty introduced the right to the ECI. The aim is to actively involve citizens in the European decision-making, giving them an indirect form of legislative initiative. Information technologies (IT) are the essence of up-to-date organizations in general, and changes in this field are occurring at an uncontrollable pace, interrupting traditional models and forcing organizations to implement new models, new ways of working and communicating. In this context, the European Commission, not ignoring the relevance and transformations inherent in the use of IT, has included its use in several areas, namely in the European Citizens’ Initiative. In this research is analysed how much a platform available in the European Citizens’ Initiative context is used in petitions and the evolution of this same use until the completion of the review in 2018.
Aprovechamiento de las Redes Sociales como medio de participación ciudadana para validar posiciones e intereses de política internacional en el contexto de la diplomacia pública digital. Estudios de caso
Authors: Hernández Pereira Rosmery
Published: July 2019

The objective of this research is to analyze the role of social networks in digital public diplomacy as well as citizen participation in validating the positions and interests of States and governments. It is based on three phases of content analysis: a) internal analysis of the content or publication b) causes c) effects (Alonso, Volkens and Gómez, 2011). For one year (2017-2018), the posts of four States, two European and two American, were followed up as case studies. Special attention was paid to the social networks of heads of state in relation to issues of international interest, and a comparison was made through content analysis. From July 2017 onward, a systemization of the posts encountered was initiated. The main results show an active, participatory role on the part of public users– citizens. We can speak of the phenomenon of the global citizen (Martínez, 2004). For their part, decision makers/ government leaders have an active role in social networks and seek to communicate and validate their actions, almost from the moment they make or announce their decisions, in order to know the reactions of citizens. States make use of social networks in the context of what is defined as digital public diplomacy.
Género y poder en la ficción televisiva: análisis textual ideológico de una serie histórica
Authors: Donstrup Mayte
Published: July 2019

Productions carried out during the third golden age of television enjoy widespread popularity today. Within some of the TV series in this category, women who hold positions of power can occasionally be found as in the TV show analyzed in this article, which
is Vikings. In this series, one of the main protagonists, Lagertha, amasses great admiration from the female audience. In order to know if this success corresponds to the reality of the character (her personality and the actions she takes), this study will carry out
an analysis to determine the archetype of the protagonist and to develop a semiotic study of the character and her power relations with other subjects.
El lenguaje visual del diseño web brutalista
Authors: Suárez-Carballo Fernando
Published: July 2019

Many authors agree on the current relevance of brutalist web design, a trend inspired by the popular architectural style which, in turn, is distinguished by the rawness of its materials, the geometric shapes or the absence of decoration. This study uses Content Analysis to discover whether it is possible to interpret web-brutalism as a movement with distinctive features and, if this is found to be the case, to make a description of the term based on visual communication techniques as the main variable. After evaluating 50 websites from the catalogue of Brutalist Websites, the study concludes that the most recent meaning refers to a highly heterogeneous movement whose works, based mainly on visual tension, only share the attributes of provocation and creative freedom, which brings it closer to other contemporary trends in postmodern graphic design, such as New Ugly.
Un estudio de las representaciones familiares y socioafectivas en la publicidad de juguetes en Navidad
Authors: Nicolás Ojeda Miguel Ángel , Martínez Pastor Esther , García Manso Almudena
Published: July 2019

This study analyses toy advertising broadcast in Spain over the 2014/15 Christmas period. The goal is to begin a quantitative review of how family is represented in commercials. Initially, it reviews the concepts of childhood, relates them to the concept of socialisation and offers a short analysis of the advertising phenomenon. The results evaluate the presence of types of emotions, values and actions associated with the gender of the characters featured, and the frequency of parent –and grandparent– character appearances in toy ads targeting children is quantified. The limited presence of these characters establishes a basis for discussion about the role of said characters as necessary figures of reference and authority in child development. A final reflection is also proposed regarding the homogeneity of the representations of gender associated with the characters’ roles, for both adults and children. Lastly, this paper justifies interest in widening the study to international level, to make it possible to check the degree of similarity and of contrast in said representations as a way to contribute to understanding and viewing the family in advertising discourses.

Published: July 2019

Los medios móviles (smatphones y tabletas) les permite a los menores tener unos hábitos más flexibles y personalizados, y crear nuevas oportunidades de uso privado dentro del hogar, la escuela y el espacio público. El proyecto Net Children Go Mobile[1], en el que han participado Dinamarca, Italia, Reino Unido, Rumanía, Bélgica, Irlanda, Portugal y España, se basa en el análisis de esta nueva realidad y de sus posibles consecuencias para la infancia. Esta comunicación presenta los resultados más significativos de este proyecto en España a partir de la encuesta realizada a 500 menores españoles usuarios y usuarias de internet de entre 9 y 16 años y a su padre o a su madre. Uno de los mayores hallazgos de este proyecto es que las experiencias de riesgo online no conducen necesariamente al daño, tal y como indicaron los propios menores. De hecho, la investigación EU Kids Online mostró que los niños y niñas que se encuentran con mayor número de riesgos online no son necesariamente quienes sufren consecuencias más dañinas; por el contrario, normalmente son ellos quienes demuestran más habilidades y desarrollan más resiliencia.

Estimasi State-Of-Charge Menggunakan Simulink Pada Baterai Pembangkit Listrik Tenaga Surya
Authors: Sugeng Bambang , Saputra Riza Hadi
Published: July 2019

Sudah tidak bisa ditutupi lagi bahwa saat ini Indonesia sedang krisis energi dimana permintaan lebih banyak daripada pemasokan energi listrik. Hal ini juga diiringi dengan semakin canggih teknologi akan semakin banyak membutuhkan energi listrik. Oleh karena itu, saat ini juga sedang disibukkan penelitian tentang energi terbarukan dimana bisa membantu perusahaan energi listrik konvensional. Salah satu energi terbarukan tersebut adalah pembangkit listrik tenaga surya, dimana energi cahaya matahari yang terserap ke sel surya dalam bentuk foton yang ketika energi ini mengenai permukaan sel surya, maka elektronnya akan tereksitasi dan menimbulkan aliran listrik. Namun tidak hanya komponen sel surya yang ada pada pembangkit listrik tenaga surya, ada beberapa bagian yang salah satunya adalah baterai sebagai tempat penyimpanan listrik. Baterai sangat berperan penting dalam pembangkit listrik tenaga surya. Jika baterai tidak diawasi dengan benar, maka baterai dapat mengalami penurunan performansi dan hal ini berkesinambungan dengan penurunan performansi dari sel surya. Ada beberapa parameter yang dapat mempengaruhi performansi baterai yang salah satunya adalah SOC (State-of-Charge). Dalam penelitian ini bertujuan untuk mengetahui estimasi SOC dengan aplikasi MATLAB dan pemodelan SIMULINK. Hasil yang didapatkan adalah baterai bekerja pada rentang SOC 30% untuk batas bawah dan 90% untuk batas atas dengan asumsi baterai yang digunakan adalah baterai baru yang belum mengalami banyak siklus pengisian dan pengosongan.
The Locus of Innovation: A Literature Review
Authors: Han Yongliang Stanley
Published: July 2019

The most commonly asked question in the research of innovation is: what type of firms can innovate more productively, startups or established firms? A related question is: does the nature of innovation affect the comparative advantages of startups versus established firms? This paper reviews the literature on the locus of innovation from multiple perspectives, including explanations based on organizational capabilities, incentives and agency costs, transaction cost economics, and property rights theory. It seeks to provide an integrative view of the comparative advantages of startups versus established firms when handling innovation. Prior research on the locus of innovation has significant implications not only for the theory of innovation, but also for the theory of the firm. Most notably, integration is primarily motivated by coordination benefits and improved incentives for investment in non-human assets (Williamson, 1985; Grossman & Hart, 1986; and Hart & Moore, 1990). However, integration suffers from weaker incentives to invest in human assets (Holmstrom, 1989).

Aim: To compare the effect of smear layer removal with 17% EDTA and Nd:YAG laser on the apical microleakage of two resin based sealers.

Materials and Methods: Sixty freshly extracted maxillary central incisor teeth with patent canals were selected. The teeth were debrided and stored in saline for 24 hours before use. The teeth were sectioned at CEJ & cleaning and shaping were done upto 50 size by step back technique. The following groups were analyzed.

GROUP 1:  Gutta percha (GP) + AH plus sealer without smear layer removal.

GROUP 2:  GP + RC seal sealer without smear layer removal.

GROUP 3:  GP + AH plus treated with 17% EDTA.

GROUP 4:  GP + RC seal treated with 17% EDTA.

GROUP 5:  GP + AH plus treated with Nd:YAG laser. GROUP 6:  GP + RC seal treated with Nd:YAG laser.

8 samples were subjected to dye penetration study for apical microleakage & 2 samples were subjected to SEM in each group to show the effect of smear layer removal by EDTA and laser.

The data were analyzed by using ANOVA and TUKEY-HSD test.

Results: Groups 1 and 2 showed maximum microleakage , other groups showed lesser microleakage but there was no statistically significant difference between laser and EDTA treated Groups. 

Conclusion: EDTA and Nd:YAG laser can be effectively used to  remove smear layer and showed less apical microleakage compared to non-treated groups.

Keywords: 17% EDTA, Nd:YAG LASER , AH plus , RC sealer ,  Smear layer.
Contra pan-institutionalism. Part I
Authors: Kapeliushnikov Rostislav I.
Published: July 2019

The paper provides a critical assessment of Pan-i nstitutionalism — an approach which tries to explain the course of the world economic history by changes in formal economic and formal political institutions. This approach is mono-causal since for it formal institutions do not simply matter: in fact they are all that matter. The most complete and elaborated versions of Pan-institutionalism were presented i n two famous books — “Violence and social order” by North, Wallis and Wei ngast and “Why nations fail” by Acemoglu and Robinson. Their ideas were taken by the Russian academic community as the last word in the modern economic and political sciences. The paper demonstrates methodological narrowness, conceptual inconsistency and historical inadequacy of Pan-institutionalism. In particular, it fails to provide a coherent explanation of the turning point of the world economic history — the Industrial revolution in England in the mid of XVIII century, i.e. a transition from Malthusian to Schumpeterian economic growth.

Authors: Trofimov Sergey E.
Published: July 2019

The article analyzes topical issues of the state regulation of subsurface use of the Arctic and continental shelf of Russia. The role and value of development of oil and gas reserves of the Arctic as the most important strategic region of development of national economy are proved. The need of tough upholding of the Russian Arctic interests for the UN and other international organizations is revealed. The anti-sanctions policy of import substitution in relation to the foreign oil and gas equipment and technologies of extraction of hydrocarbon raw materials in extreme conditions, to construction of the drilling fleet, etc. from positions of national energy sustainability is grounded. The importance of studying the best practices of the subarctic states is noted.

Drveće i grmlje u sustavu gradskog zelenila ima niz
različitih uloga: funkcionalnih, estetskih, društvenih, ekoloških i
gospodarskih te su značajni element svakog grada. Prema podacima o bilansu
namjene u obuhvatu Urbanističkog plana grada Bihaća, planirane i postojeće
zelene površine zauzimaju oko 553 ha urbanog područja. Cilj rada je bio analiza
i istraživanje stavova o društvenoj funkciji i općem stanju zelenila u Bihaću. Anketno
istraživanje je provedeno tijekom mjeseca siječnja 2018. godine na različitim
lokacijama grada Bihaća.
Rezultati istraživanja su pokazali da je ispitanicima Gradski park najomiljenija zelena
površina. Preferiraju povećanje zelenih površina u gradu i daju na značaju edukaciji građana o važnosti istih. Smatraju da bi održavanje zelenila Gradskog parka trebali
obavljati i građani. Posebno su istaknuli problem loše osvijetljenosti u
navedenom parku, kao i nedostatak klupa te koševa za smeće, pojavu vandalizama
itd.

U radu su prikazani rezultati utvrđivanja sadržaja
arsena u plodovima dvije sorte nektarina na tri lokacije Hercegovine (Mostar,
Čapljina i Stolac) tijekom 2015. i 2016. godine. Nakon utvrđivanja sadržaja
arsena u plodovima nektarina, uradio
se proračun procjene rizika proračunom nekancerogenog indeksa opasnosti (Hazard Quotient Index, HQI; Indeks
koeficijenta opasnosti). Na istraživanim lokacijama uzgajane su dvije
sorte nektarina (Big Top i Caldesi
2000). Sadržaj arsena u 2015. godini je utvrđen samo na lokaciji Stolac. U
2016. godini na svim lokacijama je bio ispod LQO (Limit of Quantification,
Granica kvantifikacije). Procjenom dnevnog unosa (Estimated daily intake, EDI) i tjednog unosa (Estimated weekly intake, EWI) arsena navedenim sortama nektarina
utvrđeno je da nema akutnog ni kroničnog rizika na zdravlje ljudi.

Published: July 2019

A curva característica de água no solo é um importante fator para descrever o comportamento físico-hídrico dos solos pois é de grande importância na agricultura, por apresentar aplicações científicas, técnicas e práticas. Desta forma, a estimativa da mesma pode ser feita através de diversos métodos, sendo o mais utilizado o método da câmara de Richards. Assim, o objetivo desse trabalho foi avaliar o modelo proposto por Arya e Paris, para estimar a umidade volumétrica para duas classes de solo, com base na análise textural. Foram selecionados na literatura solos oriundos de duas classes texturais e três locais de origem, onde foram utilizados os dados texturais para realizar a estimativa da curva de retenção de água no solo através dos parâmetros de Van Genuchten gerados através do programa Qualisolo e comparar com a curva gerada pelo método direto. Os resultados obtidos mostraram uma subestimação dos valores de umidades estimadas para os solos analisados, apresentaram coeficiente de determinação superiores a 0,87 relatando uma boa correlação entre as umidades observadas e estimadas. Portanto, conclui-se que os resultados mostraram uma boa alternativa de uso do método proposto por Arya e Paris para gerar a curva de retenção de água no solo de maneira satisfatória.

O objetivo deste trabalho foi determinar a dose, época e número de aplicação ideais de ácido metil salicílico (ASM) para o controle da giberela durante a antese e sua influência sobre as características agronômicas da cultura do trigo. O delineamento experimental utilizado foi de blocos casualizados, em esquema fatorial triplo 2x3x4, sendo duas cultivares de trigo, três épocas de aplicação e quatro doses, com três repetições. Avaliou-se o tamanho da espiga, peso da espiga, número de grãos por espiga, número de espiguetas estéreis por espiga, incidência e severidade de giberela, peso de mil grãos e produtividade. As variáveis analisadas foram submetidas à análise de variância e quando significativas os fatores qualitativos foram submetidas à comparação de médias pelo teste Tukey a 5% de probabilidade, e para os fatores quantitativos, realizou-se a análise de regressão. Duas aplicações de ASM, realizadas no início + ½ da antese condicionam menor número de espiguetas estéreis na cultura do trigo. A dose de 37,5 g ha-1 de ASM proporciona baixos percentuais de incidência e severidade de giberela em grãos de trigo, sugerindo inserção do ASM no manejo integrado da doença. A dose de 12,5 g ha-1 de ASM condiciona incremento na produtividade de trigo.
