Published: June 2019

Introduction

The purpose of this study was to evaluate the relationship between the severity of cognitive impairment and the results of stabilographic tests in elderly patients with cognitive impairment.

Methods

The study involved 42 participants aged 62–84 (mean 73.4 ± 6.7) years. The assessment of cognitive status was carried out with the Mini-Mental State Examination (MMSE). Included were subjects who obtained a score below 27, which is the cut-off score between the absence and presence of cognitive impairment. Postural stability was evaluated by using a force platform which registered the shifts of the centre of pressure (CoP) in the sagittal and frontal plane during two 32-second trials of quiet stance on a hard surface, with eyes open and with eyes closed. The CoP sway parameters were analysed.

Results

In the eyes-open test, we obtained a weak negative correlation of the MMSE and the mean radius of the CoP sway (r = –0.37; p < 0.05). Considering the values achieved in each plane, a statistically significant correlation was observed in all the parameters analysed in the sagittal plane. The eyes-closed test revealed a clear negative correlation between the MMSE results and all the studied parameters.

Conclusions

A significant relationship between the severity of cognitive impairment and the results of stabilographic parameters were noted. A negative correlation between the stabilographic parameters and the MMSE scores showed a linear deterioration of postural stability which progresses along with the decrease in cognitive functions.
A Telehealth Privacy and Security Self-Assessment Questionnaire for Telehealth Providers: Development and Validation
Authors: Zhou Leming , Thieret Robert , Watzlaf Valerie , DeAlmeida Dilhari , Parmanto Bambang
Published: June 2019

Background: Telehealth is a great approach for providing high quality health care services to people who cannot easily access these services in person. However, because of frequently reported health data breaches, many people may hesitate to use telehealth-based health care services. It is necessary for telehealth care providers to demonstrate that they have taken sufficient actions to protect their patients’ data security and privacy. The government provided a HIPAA audit protocol that is highly useful for internal security and privacy auditing on health care systems, however, this protocol includes extensive details that are not always specific to telehealth and therefore is difficult to be used by telehealth practitioners.Objective: The goal of this study was to develop and validate a telehealth privacy and security self-assessment questionnaire for telehealth providers. Methods: In our previous work, we performed a systematic review on the security and privacy protection offered in various telehealth systems. The results from this systematic review and the HIPAA audit protocol were used to guide the development of the self-assessment questionnaire. The draft of the questionnaire was created by the research team and distributed to a group of telehealth providers for evaluating the relevance and clarity of each statement in the draft. The questionnaire was adjusted and finalized according to the collected feedback and face-to-face discussions by the research team. A website was created to distribute the questionnaire and manage the answers from study participants. A psychometric analysis was performed to evaluate the reliability of the questionnaire.Results: There were 84 statements in the draft questionnaire. Five telehealth providers provided their feedback to the statements in this draft. They indicated that a number of these statements were either redundant or beyond the capacity of telehealth care practitioners, who typically do not have formal training in information security. They also pointed out that the wording of some statements needed to be adjusted. The final released version of the questionnaire had 49 statements. In total, 31 telehealth providers across the nation participated in the study by answering all the statements in this questionnaire. The psychometric analysis indicated that the reliability of this questionnaire was high.   Conclusion: With the availability of this self-assessment questionnaire, telehealth providers can perform a quick self-assessment on their telehealth systems. The assessment results may be used to identify possible vulnerabilities in telehealth systems and practice or demonstrate to patients the sufficient security and privacy protection to patients’ data.
Investigating Student Engagement in First-Year Biology Education: A Comparison of Major and Non-Major Perception of Engagement Across Different Active Learning Activities
Authors: Hymers Devin , Newton Genevieve
Published: June 2019

Educational techniques that improve student engagement have repeatedly been shown to improve performance at the class level at many institutions and in multiple disciplines. However, knowledge of engagement in individual activities in large first-year classes, where there may be several sub-populations of students in different programs reflecting varied interests, is limited. In this study, we examined two large, lecture-based, introductory first-year biology classes to determine whether there were any relationships between specific learning activities and student engagement and performance, both at the class level and as broken down by program of study. Surveys were used to quantify the level of student engagement through four activities: (a) student response systems (clickers), (b) in-class discussions and activities, (c) lab and seminar activities, and (d) interdisciplinary learning. Engagement scores were then compared to students’ final grades. Students in all majors who reported higher levels of participation in most activities studied also reported feeling more engaged overall and achieved higher grades than their less-engaged peers; however, students in non-biology majors demonstrated notably weaker relationships between their engagement and performance in biology courses, where such relationships existed at all. In this paper, we discuss the learning activities which are associated with the greatest performance increases in both biology and non-biology majors and suggest how these results may be used to inform instructional techniques to benefit all students, regardless of major, in future course offerings.

Published: June 2019

The 3M National Teaching Fellowship (3MNTF) has been part of the Canadian higher education landscape for the past 31 years and has grown to be a community of 328 fellows, with up to ten more being added each year. As part of the 30-year anniversary of the Fellowship, we initiated a study to understand its impacts on the higher education community by examining the effect that the Fellowship has had on individual winners, the influence that fellows have been able to exert in their institutions after being awarded the 3M Fellowship, and the influence that the 3M National Teaching Fellowship program has had nationally and internationally. To identify the various impacts of the 3MNTF, we conducted focus groups with the 2012 cohort, 3M retreat facilitators and coordinators, and the representative from 3M Canada, as well as the new fellows from the 2013 cohort. In 2014, we conducted two focus groups with senior university administrators and educational developers. In 2015, we developed and administered an online survey to faculty, administrators, educational developers, and students at a number of Canadian universities. We found that the 3M is one of the most recognizable teaching awards in Canada’s higher education landscape. The structure of the fellowship has helped to shape local and international teaching awards, while individual fellows often provide mentorship to future leaders in education.
Thinking Beyond Writing Development in Peer Review
Authors: Chaktsiris Mary G. , Southworth James
Published: June 2019

The benefits of a peer review process tend to be evaluated in terms of improvements to students’ writing. But are there reasons why instructors might want to implement peer review into their courses over and above writing development? In this study, we collected data from 30 university students on their perceptions of a peer review process. Although we found little revision of student work from draft to final paper, we were surprised to learn that students found the process useful. We found that the peer review process helped students develop non-cognitive skills. In particular, it helped them to develop (a) self-discipline, which helped with their time management, and (b) resilience in overcoming anxiety, which helped them to integrate in a social network.

Published: June 2019

This study focused on verifying the Time of concentration Equation for a more reliable design of drains. Tracer studies were carried out in 1000m long rectangular drains at the University of Nigeria Nsukka. Sodium Chloride which was used as the tracer was introduced at station 1 and samples were collected after 20secs simultaneously at the 9 collection points. Flow parameters including velocity and slope of channel were determined. The collected samples were analyzed in the laboratory for determination of chloride concentration in mg/l. The maximum concentration was 42.11mg/l. Thereafter the time of concentrated was computed by dividing the summation of product of concentration and measured time with the summation of concentration. Through regression analysis, a modified formula for computing time of concentration (tc). Model verification was carried out using experimental data. The results from obtained from the modified Equations were compared respectively with computed results from the commonly used Kirpich formula and measured times of concentration. The results showed no correlation between measured and computed values. There were also marked variations between results from existing and modified formulae. There is therefore need for further verification and validation of the modified Equation. This is necessary in view of the fact that a reliable prediction of time of concentration is key to a cost effective drainage design.
New Research into the Early and Middle Bronze Age in Central Jordan: The Site of Murayghat
Authors: Kerner Susanne
Published: June 2019

The site of Murayghat, southwest of Madaba, consists of a central limestone knoll (Area 1) with numerous structures built from standing stones, single orthostat stones (Hadjar al-Mansoub), dolmen fields overlooking them, and domestic architecture situated around the central knoll. The dolmens, standing structures, and lower levels of the architecture date into the Early Bronze Age, while a reuse of the site is attested from the Middle Bronze Age. The dolmens are simple trilithon structures, which show planning and a relation with the possible cultic center. The EB I architecture features apsidal rooms and large walls made from orthostats similar to those on the central knoll. The site fits into the Early Bronze Age development of large cemetery structures related to settlement sites. The “Ritual Landscapes of Murayghat” project is carried out by the University of Copenhagen.

Managing a Country’s Sustainabilty - The Case of Malaysia and Indonesia Public Debt
Authors: Hadi Abdul Razak Abdul , Aspiranti Tasya , Iqbal Tahir , Rehan Raja
Published: June 2019

The study is driven by the motivation to examine the effects of policy interest rates and crude oil prices on Malaysian and Indonesian government borrowing within the framework of Keynesian macroeconomic theory. Using Autoregressive Distributed Lag (ARDL) model as an estimation tool over the observed period from March 2013 till June 2018, the study uncovers the absence of long-term equilibrium relationship between government borrowings and the two explanatory variables. However, based upon Error Correction Representation via ARDL model, there is a significant long-run relation (at 10% level) between Indonesian government borrowing and the two tested variables. Interestingly, this is not the case for Malaysia over both long-run and short-run relations. With respect to the short-run dynamics, there is a unidirectional causality running from crude oil price to Indonesian government borrowing. It seems crude oil price plays a significant role in influencing Indonesian government’s choice of public financing. As expected, the short-term policy rate has no significant bearing on government borrowings at all.

Published: June 2019

The main purpose of this study is to investigate an important issue in behavioural finance area that is the role of investor sentiment in determining firm performance, alongside with market timing and other fundamental firm factors in the context of Malaysian market. The impact of pre and post financial crisis during study period of 2004 to 2015 is incorporated in the analysis. The study uses a balanced panel data of 143 IPO firms in Malaysia during the study period. The sentiment index is developed using panel data cross section based on three IPOs proxies, which are IPO volume, market turnover and dividend premium. The findings indicate that market timing is found to have a strong influence towards firm performance with a positive and high level of significance relationship during pre and post financial crisis. Whereas investor sentiment does influence firm performance, particularly when timing is proxied by initial return before the financial crisis period. Other firm specific factors, growth show very strong positive relationship with firm performance. The remaining factors, namely tangibility of asset, profitability, size and industry show mix results either consistent or inconsistent with past literature irrespective of pre or post financial crisis. The finding offers a useful reference for firm managers’ to consistently time the market for the new and subsequent issue. While the investors have to pay attention on important information available in the market than become overly optimistic about future prospect of any investment as firm will continue to exploit timing strategy in their financing decision.

Published: June 2019

As constantes alterações no cenário econômico brasileiro impactaram diretamente os níveis de desemprego, obrigando os agentes a tomarem decisões importantes em relação a manutenção de suas rendas. Uma das alternativas utilizadas para essa finalidade é o empreendedorismo, via criação do próprio negócio. Contudo, tomar esta decisão envolve diversos fatores, sendo importante identificá-los e mensurá-los. Assim, o presente estudo objetivou analisar as características que determinam a decisão de empreender e estimar como a religião pode afetar essa decisão. Mais especificamente o estudo verificou a relação entre a religião protestante e a decisão de empreender, controlando para outros fatores apontados pela literatura. Para tanto, a base de dados utilizada foi construída por meio dos microdados dos Censos Demográficos de 1991, 2000 e 2010. Os dados foram modelados por meio do modelo de Regressão Logística e os resultados apontam que ser protestante eleva as chances de ser empreendedor em 10,30%, 8,2% e 2%, respectivamente em relação a 1991, 2000 e 2010 e 3,3% em relação a amostra total, mostrando que a religião é um fator que deve ser considerado ao se analisar os determinantes do empreendedorismo.

Published: June 2019

We aimed to evaluate whether the air temperature, soil temperature, and luminosity in a low tunnel covered with agricultural mesh screening affected the characteristics of kale production. The study was conducted on the cultivation of kale in six different growing environments. The experimental setup consisted of randomized block design (RBD) with factorial analysis (2 × 6) with four repetitions. The kale (Brassica oleracea L. var. acephala) hybrids Hi Crop and Kobe F1 were used as plant material. The growing environments were open field and protected environments consisting of low tunnels, each covered with a different mesh screen: red, thermo-reflective silver, black, tissue-non-tissue (TNT), and organza fabric. Sensors were installed within each environment to monitor air temperature and soil temperature. The TNT screen resulted in the highest air and soil temperatures and lower yield. The black mesh resulted in lower temperatures than other coverings. Organza fabric provided the best yield (22.8%) compared to open field and it was 9.89to42.19 % more productive compared to the other meshes. Organza fabric was the best environment for the cultivation of kale in tropical climates. These data confirm that kale biomass production was greatly affected by stress high temperature.

Published: June 2019

The evaluation of the forest restoration scenario is of great importance, with floristic composition and diversity being among the most used ecological variables as indicators. This research aimed to identify the current situation, in terms of species composition and diversity, of two riparian forests under restoration based on a reference ecosystem, the Brazilian Atlantic Forest. Twenty permanent plots (250 m²) were located in areas under restoration process (AR1 and AR2) and in a forest fragment of the region which served as a reference ecosystem (ER). We sampled, identified and classified all tree individuals with CBH ≥ 15.0 cm in each plot. Aiming to understand species richness and diversity, besides the traditional indexes (Shannon and Simpson), we also estimated the effective numbers of Hill’s diversity (qD = 0, 1 and 2) considering rarefaction (P ≤ 0.05); and to detect floristic similarities among the study areas we performed a Principal Coordinate Analysis (PCoA). We found dissimilarity among ARs and ER, and the presence of exotic species, indicating that, as recommended, such reference should have been taken into account during the planning of the restoration action. Considering the effective numbers of species (qD) we found differences between the areas, species richness and diversity was higher in ER > AR2 > AR1. We also show that among the restoration areas, with the same age and submitted to the same conditions, AR2 has features that allow us to conclude that this area has a bigger chance of success in the restoration process. However, aiming environmental sustainability, we suggest that some corrective actions should be taken in order to favour the reestablishment of ecological processes in these areas.

The study on nutritional needs of the tree species T. vulgaris, has a great contribution to the formation and conduction of plantations, resulting in their choice in terms of the potential that has been demonstrated in the comparative trials of fast growing species (more than 0.60 m/year in height) and strong regional demand for firewood and coal. The objective of this study was to evaluate the growth of T. vulgaris in response to the application of nitrogen, phosphorus and potassium, from the beginning of the establishment until the second year after planting. The study was carried out in the municipality of Igarapé-Açu-PA, in a T. vulgaris plantation of 1.44 ha (14,400 m2), spacing of 2 m × 3 m (plants × lines). The treatments consisted in the use of commercial products urea, super triple phosphate and potassium chloride as source of N-nitrogen, phosphorus-P2O5 and potassium-K2O respectively, forming 8 treatmentswhich were analyzed using measures repeated in time. Treatment with combined doses of nitrogen and potassium contributed to a higher growth in height and diameter when compared to plants without fertilization. Fertilization of nitrogen (26.67 g) plus potassium (30 g) contributed to a higher planting growth.
Effect of Various Metal Hydroxide Flame Retardants on the Rheological Properties of Asphalt Binder
Authors: GU Lingzhu , ZHANG Tianhang , ZHU Kai , TANG Daquan , WU Ke
Published: June 2019

Metal hydroxide has been widely used as flame retardant to reduce the hazards of tunnel fire, however, few researches investigate its effect on the rheological properties of asphalt binder systemically. This study explores and compares the effect and mechanisms of magnesium hydroxide (MH), aluminium hydroxide (ATH), hydrated lime (HL), and layer double hydroxides (LDHs) on the rutting resistance, anti-aging resistance, as well as the thermal cracking resistance of asphalt binder. Rotational viscosity (RV) test, dynamic shear rheometer (DSR) test, and bending beam rheometer (BBR) test are involved in the project. Test results indicate: (1) the addition of metal hydroxide generally improves the rutting resistance of asphalt binder during high temperatures due to the typical filler effect, while weakens the resistance to thermal cracking of binder at low temperatures because of the stress concentration; (2) HL and LDHs enhance the anti-aging resistance of asphalt binder; (3) LDHs modified binder, which is proved with better rheological properties, including great rutting resistance, anti-aging resistance and passable resistance to thermal cracking, is recommended for further use. However, the high procurement price is still a big obstacle for its wider application. DOI: http://dx.doi.org/10.5755/j01.ms.25.3.21572

Large scale developmental projects firstly require the selection of one or more cities to be developed. In Libya, the selection process is done by selected organizations, which is highly influenced by human judgement that can be inconsiderate of socioeconomic and environmental factors. In this study, we propose an automated selection process, which takes into consideration only the important factors for city (cities) selection. Specifically, a geospatial decision-making tool, free of human bias, is proposed based on the fuzzy overlay (FO) and technique for order performance by similarity to ideal solution (TOPSIS) techniques for development projects in Libya. In this work, a dataset of 17 evaluation criteria (GIS factors) across five urban conditioning factors were prepared. The dataset served as input to the FO model to calculate weights (importance) for each criterion. A support vector machine (SVM) classifier was then trained to refine weights from the FO model. TOPSIS was then applied on the refined results to rank the cities for development. Experimental results indicate promising overall accuracy and kappa statistics. Our findings also show that highest and lowest success rates are 0.94 and 0.79, respectively, while highest and lowest prediction rates are 0.884 and 0.673, respectively.
On the Difference Between Being and Object
Authors: Osborn James ,   DePaul University
Published: June 2019

If philosophy in the wake of Kant’s transcendental revolution tends to orient itself around a subjective principle, namely the human subject, then recently various schools of thought have proposed a counterrevolution in which philosophy is given an objective, nonhuman starting point. In this historical context, “object-oriented ontology” has sought to gain the status of first philosophy by identifying being in general with the object as such—that is, by systematically converting beings to objects. By tracing the provenance of this system to a key moment of late eighteenth-century German philosophy, this paper develops the idea of the difference between being and object in order to demonstrate that object-oriented thinking, contrary to its anti-Kantian claims, adheres to the central axiom of transcendental idealism, that this axiom contains an unsolvable paradox, and that Kant and Novalis give us the resources for a transformative philosophical project that meets the challenge of the cultural and theoretical turn to objects.
Escrever é resistir. Práticas de resistência nos Papéis da Prisão de Luandino Vieira
Authors: Scaraggi Elisa
Published: June 2019

Neste trabalho, seguindo as linhas base definidas por pesquisas históricas (Buntman 2003; McEvoy 2015), exploro o conceito de resistência no contexto da prisão, destacando como as condições materiais são essenciais para que haja resistência, e para determinar a forma que esta assume. À luz destas considerações, procedo à análise de alguns aspetos da obra Papéis da Prisão (2015), de José Luandino Vieira. Preso político durante a luta pela independência de Angola, José Luandino Vieira escreveu a maior parte de sua literatura de ficção durante a reclusão, além de dezessete cadernos de apontamentos que foram recentemente publicados com o título Papéis da Prisão. O meu objetivo não é só analisar os Papéis como exemplo de resistência em si, mas também observar as diferentes práticas de resistência que a obra descreve.
Escrever outra vez: luto e jogo em Quatro-Olhos, de Renato Pompeu
Authors: Conde Miguel Bezzi
Published: June 2019

Argumento neste ensaio que o romance Quatro-olhos (1976), de Renato Pompeu, oscila entre luto e jogo ao falar da vida durante a ditadura militar brasileira (1964-1985). Essa ambivalência pode ser compreendida como uma forma de assinalar as perdas irrecuperáveis causadas pela violência autoritária, sem deixar de buscar reinscrever no presente também um gesto de insubordinação que evite a paralisia melancólica. A escrita se define como a tentativa de “escrever outra vez” um livro apreendido pela repressão política e desde então desaparecido. No ato de “escrever outra vez”, o que retorna e se repete do passado não são pessoas, coisas ou projetos, mas o próprio gesto da escrita. Incapaz de recuperar o perdido e desfazer o que aconteceu, ele se assume também como gesto de invenção. As lacunas da recordação se tornam um espaço de experimentação e o luto se faz acompanhar do jogo.
Ética e estética da poesia marginal
Authors: Arevalo Gutierrez Debora Priscila , Cei Vitor
Published: June 2019

A antologia 26 poetas hoje, organizada e publicada por Heloisa Buarque de Hollanda em 1976, evidencia que ética e estética são duas dimensões absolutamente imbricadas na poesia marginal brasileira dos anos 1970. Este artigo tem como objetivo identificar e examinar as principais características éticas e estéticas da crítica que a poesia marginal fez da ditadura militar no Brasil. Destaca-se que a poesia marginal recusava o status quo, a favor da experimentação e da resistência, de modo que a intersecção entre estética e ética assume grande relevância política, como pode ser verificado na antologia. Conclui, preliminarmente, que a experiência estética passa a se constituir uma via de acesso para a vida ética.
Diagnóstico de disposições irregulares de resíduos de construção e demolição (RCD) em Frederico Westphalen-RS
Authors: Medeiros Raphael Corrêa , Patatt Eduardo Ruwer
Published: June 2019

Com a intensificação da geração e dos problemas ambientais causados pelas disposições irregulares dos resíduos de construção e demolição nos municípios brasileiros, as administrações públicas vêm buscando formas de controlar e amenizar esses agravantes. Neste sentido, este trabalho teve a finalidade de apresentar um diagnóstico da situação atual dos RCD dispostos inadequadamente no município de Frederico Westphalen, através do levantamento de áreas de descartes clandestinos. Foram encontradas 46 áreas com despejo clandestino, grande parte são de pequeno porte e apresentaram-se, após as três vistorias realizadas, regularizadas, ativas ou inativas. Em virtude da grande incidência de áreas que ainda não foram regularizadas, 34,8% do total, ficou evidente a falta controle efetivo dessas disposições irregulares, reafirmando a ideia de que existe a necessidade de implementar um plano municipal de gerenciamento para essa classe de resíduos, caracterizando os depósitos como áreas clandestinas de RCD. Houve também o levantamento de inúmeros impactos ambientais, dentre eles, interrupção parcial de logradouro e calçamento público, presença de outros tipos de resíduos, poluição e contaminação de áreas de proteção permanente. Os dados deste trabalho podem servir como instrumento de auxílio aos órgãos públicos para o desenvolvimento de ações e diretrizes de fiscalização nessas áreas, a fim de um melhor gerenciamento desses resíduos.

Ishemična možganska kap je v pediatrični populaciji redka, vendar predstavlja pomemben vzrok nevrološke oviranosti pri otrocih in mladostnikih. Z razvojem in dostopnostjo nevroradiološke diagnostike je danes prepoznava ishemične možganske kapi zgodnejša. Vzroki in dejavniki tveganja za ishemično možgansko kap pri otroku se pomembno razlikujejo od vzrokov pri odraslih, prav tako obstajajo pomembne razlike med neonatalnim in kasnejšimi starostnimi obdobji. Med najpogostejšimi vzroki ishemične možganske kapi v pediatrični populaciji so vaskulopatije, embolije pri prirojenih srčnih napakah in protrombotična stanja. Pogosto je vpletenih več dejavnikov hkrati. Klinična slika možganske kapi pri otroku v akutni fazi ni vedno jasno izražena, zato se diagnoza lahko postavi z zakasnitvijo. Možganska kap pri otroku ne povzroči le izgube določenih možganskih funkcij, temveč vpliva na celostni razvoj otroka.Z namenom zgodnjega prepoznavanja možganske kapi prispevek posebno pozornost namenja opisu različnih kliničnih slik možganske kapi pri otrocih ter dejavnikom tveganja zanjo. Članek podaja tudi trenutne smernice oz. priporočila s področja akutne obravnave in zdravljenja, katerih cilj je zmanjšanje obsega možganske okvare in izboljšanje izida pri otroku. Prispevek obravnava pediatrično ishemično možgansko kap, ki jo opredeljuje starostno obdobje med 28. dnem in 18. letom starosti.

V zadnjih letih je t. i. omrežna perspektiva prispevala k boljšemu razumevanju delovanja možganov pri zdravih posameznikih in bolnikih z boleznimi živčevja. Razvoj neinvazivnih slikovnih metod in uporaba matematičnih orodij teorije grafov sta omogočila proučevanje zgradbe in delovanja možganskih omrežij. Povezave v strukturnih omrežjih lahko rekonstruiramo s pomočjo difuzijskega magnetnoresonančnega slikanja, funkcijske slikovne metode pa omogočajo proučevanje funkcijskih omrežij. Možganske sposobnosti so odvisne od topologije omrežij, ki omogočajo tako segregacijo funkcije kot tudi integrativno procesiranje informacij. Prispevek je dostopen uvod v osnove teorije grafov in nevroznanosti omrežij. Predstavi mere topologije omrežij in osnovne značilnosti možganskih omrežij pri človeku. Članek pojasni, kako bolezenski procesi prizadenejo delovanje možganov kot omrežja, in prikaže primere prenosa v klinično prakso. Izpostavimo tudi nekaj omejitev in izzivov, s katerimi se srečuje to hitro razvijajoče se področje nevroznanosti.

Lice zavzema največji del obraza in je pogosto mesto nastanka pridobljenih mehkotkivnih sprememb. Najpogostejši vzroki so poškodbe in kožni malignomi. Slednje je potrebno izrezati z varnostnim robom, kar ima za posledico velike tkivne vrzeli. Za kritje take vrzeli na licu primarni šiv rane ni mogoč, zato moramo razmisliti o načinu rekonstrukcije z VY, cervikofacialnim ali submentalnim režnjem. Cervikofacialni reženj smo uporabili za kritje vrzeli vzdolž celotne nazolabialne gube v 1. estetski podenoti lica, VY reženj za kritje velike vrzeli superomedialnega dela te podenote, submentalni pa za kritje velike vrzeli v 2. estetski podenoti. Prispevek temeljito opisuje njihove značilnosti, tehnike priprave in klinične primere. Za boljše razumevanje opiše tudi estetske podenote, kožne linije in del anatomije obraza.

Background

Spring bread wheat (Triticum aestivum L.) represents the main cereal crop in Northern Kazakhstan. The quality of wheat grain and flour strongly depends on the structure of gluten, comprised of gliadin and glutenin proteins. Electrophoresis spectra of gliadins are not altered by environmental conditions or plant growth, are easily reproducible and very useful for wheat germplasm identification in addition to DNA markers. Genetic polymorphism of two Gli loci encoding gliadins can be used for selection of preferable genotypes of wheat with high grain quality.

Methods

Polyacrylamide gel electrophoresis was used to analyse genetic diversity of gliadins in a germplasm collection of spring bread wheat from Northern Kazakhstan.

Results

The highest frequencies of gliadin alleles were found as follows, in Gli1: -A1f (39.3%), -B1e (71.9%), and -D1a (41.0%); and in Gli-2: -A2q (17.8%), -B2t (13.5%), and -D2q (20.4%). The combination of these alleles in a single genotype may be associated with higher quality of grain as well as better adaptation to the dry environment of Northern Kazakhstan; preferable for wheat breeding in locations with similar conditions.

Estimates for the 2018/2019 grain crop indicate production in the order of 238.5 million tons, an increase of 4.7% compared to the 2017/2018 harvest. This production, although satisfactory, could still be greater, were it not for the problems faced with the logistics of grain disposal where billions are lost due to the limited investment in infrastructure. The objective of this work is to establish a percentage loss index, as well as to assess these quantitative losses during bulk grain transportation of corn. The research was developed through a partnership between the National Supply Company (CONAB) and the NTA (Nucleus of Storage Technology), at the Federal University of Mato Grosso. It was established the evaluation of losses related to grain transportation in the main waterways, being bulk corn in BR 163/364 in the State of Mato Grosso. After the choice of the highways evaluated, we carried out research on the data of romaneios in the transportation of corn in bulk. The obtained data, through the romaneios, provided weight of origin, weight of destination, place of origin and place of destination, in this way, by difference was obtained the quantity of grains lost in the transport and the mileage traveled in each route. By means of these data it was possible to obtain three indices of losses, one in Kg/Km (kilogram per kilometer wheeled), another one in Kg/t (kilograms per tons transported), and also determined an index of loss in percentage of grains transported. With the indication of the indices it was possible to evaluate the losses. The Bitrem truck (7 axles) was used as the basis for calculating the losses, since during the interviews this was the type that had the most occurrences in BRs evaluated, with 39%. Based on the questionnaire, the load weight of 38,000 kg was therefore adopted. For the study of corn grain losses in road transport, 39,642 data were analyzed for routs, with 24,902,808.50 km rotated, mean of 628,19 km away by route. The amount of corn grain transported was 1,852,437,042 kg. The total losses were 1,808,951 kg, averaging 45.63 kg of loss per trip. The loss per km was on average of 0.072 kg. Transport of corn grains between Nova Ubiratã and Rondonópolis presented the highest frequency of trips (8629 trips), however the losses were 37,710 kg of grains or approximately 628 bags of corn (60 Kg). The index of percentage loss for maize (0.1025%). This percentage is lower than the adopted one that is of 0.25%, nevertheless, represent considerable losses for the economy. Based on the data obtained in the present study, it can be stated that it is possible to adopt percentage loss rates of less than 0.25% in contracts. It is recommended to adopt the percentage rates of grain loss in road transport of 0.10% for maize.

The melon plant is one of the plants with agronomic potential adult among the vegetables, for presenting high productivity in a short time. In Brazil the main producing areas are located in the owed semiarid the favourable conditions of climate for the culture, however, that area presents some factors limitations, mainly as the salinity of the soil and of the water, what carts in the decrease in the productivity and in certain cases total loss of the cultivation. The objective of that work was to accomplish a growth analysis in cycles of melon plant selection developed in a saline environment. The experiment was executed from March to May of 2017 in the Federal University of Alagoas. The appraised treatments were six cycles of melon plant (C1, C2, C3, C4, C5a and C5b) selection. The used design was in randomized complete block design in subdivided portions, being the six selection cycles the portions and the six evaluations biometrics in the time the subplots, with four repetitions. The subplots were divided into two stages in agreement with the presence of the characteristic in the vegetative stage of the plant, in that were appraised vegetative and reproductive variables. Variance analysis and test were accomplished from Tukey to 5% of probability, besides the obtaining of the earnings for selection. To determine the variable of larger importance the technique of main components it was used. Among the cycles C1 and C5a there was an increase of 15,89% of the number of leaves, that is due mainly for the small ones won to each election cycle. The selection cycles accomplished in the melon plant population promoted a small reduction in the percentile of matter dries to each selection cycle, not presenting significant difference among the cycles, with averages of 13,92; 13,10; 13.05; 12,62; 11,94 and 12,28%, respectively for the cycles C1, C2, C3, C4, C5a and C5b. NL and NFB explain about 85% of the total variation found among the selection cycles. NL presented the largest importance in the vectors and it presented correlation with several characteristics, like LMS (0.99), LSS (0.90), NBFF (0.80) and % MSPA (0.91). The selection cycles presented genetic progress as the tolerance the salinity. The number of leaves is the characteristic to be selected for obtaining of tolerant superior genotypes the salinity.
