Published: September 2020

Despite the numerous benefits of prefabricated construction method, there is unfortunately limited knowledge and adoption of this method in Nigeria’s construction industry. This study, therefore, seeks to assess the construction industry’s stakeholders’ level of knowledge and extent of adoption of prefabricated construction method in project delivery. It also evaluates the prospects and challenges of prefabricated construction considering the government’s huge annual investment in the nation’s construction industry sector. The methodology used in this study was descriptive survey involving a structured questionnaire administered to major construction industry stakeholders including the government, consultants, contractors, building material merchants, and construction financiers with practices in Nigeria’s north central geo-political zone. The study showed a low level of knowledge (MMS: 2.32) and low level of adoption (MMS: 2.13) of prefabricated construction method in Nigeria in general. It also revealed ‘Better Supervision’ (MS: 4.02) and ‘High Initial Costs’ (MS:3.62) as the highest prospects and challenges of prefabricated construction method among other identified factors. The study concluded that the low level of adoption arising from the low level of knowledge of prefab system in the nation’s construction industry was responsible for the myriad of delays in meeting project timelines, hence the prevalence of construction time–cost overruns. The current study recommends a review of the academic curriculum of built environment and professional development programmes to expand and deepen the prefab system training content. It also recommends wide adoption of prefab system considering their prospects of ensuring quality as a result of better supervision and suggests outsourcing on critical areas of organisations’ logistic weaknesses to minimize the problem of higher initial costs.
The Best Way to Access Gas Stations using Fuzzy Logic Controller in a Neutrosophic Environment

Published: September 2020

These days, Google Map is used to find any location and/or to define the route to any given place. Its accuracy is up to 30 meters but if neutrosophic numbers are used, it gives more accuracy. To check the implementation of neutrosophic numbers in Google Map, a system is developed based on Fuzzy Logic Controller (FLC) using neutrosophic numbers to find the gas station which is nearest, less parking car units and with few traffic signals on the way. In this way, it takes less time to reach the available gas station. This system enables the driver to find a fuel station with more accuracy. We took five linguistic inputs including distance, gas availability, parking car unit, amount of gas, and the number of traffic signals to get one output, that is, time. We assigned different neutrosophic soft sets to each linguistic input. FLC inference was designed using 108 rules based on if-then statements to select time to reach the gas station. The results were veriﬁed by MATLAB’s Fuzzy Logic Toolbox.
Nuovi isolani? Un'indagine sui nuovi abitanti delle isole minori della laguna di Venezia
Authors: Basso Matteo
Published: September 2020

Il saggio esplora razionalità e caratteristiche di alcune pratiche di ri-popolamento che si riconoscono oggi nelle isole minori della laguna di Venezia, contesti tradizionalmente caratterizzati da dinamiche di spopolamento, invecchiamento demografico e abbandono. Tali pratiche si configurano come una risposta individuale a un centro storico sempre più turisticizzato e offrono, in prospettiva, interessanti spunti di riflessione per politiche pubbliche volte a favorire la residenzialità a Venezia.

The scientific debate on Special Economic Zones (SEZ) shows many contributions, however the present work intends to offer an original perspective to this theme based on a comparison, through a systemic approach, between the sociourban variables, that make up the symbiotic relationships between SEZ, and urban society. A focus on the SEZ settled in the east of Naples, Italy, is also proposed, which well allows to highlight the investigated socio-urban aspects.
Protected-Denomination-of-Origin Cocoa Bean: Chain governance and Sustainability Performance
Authors: Miranda Carlos Moreno , Moreno Raúl , Moreno Pablo
Published: September 2020

The Protected Denominations of Origin in agricultural goods through recognized chains, have a fundamental economic role. In Ecuador, the pdo cocoa bean certification becomes a protagonist since it presents an opportunity to boost the social performance of smallholders. A substantial amount of research focused only on examining the crop performance of pdo products. However, there is a shift in the agricultural chain perspective towards more sustainable models. In this respect, social, economic, and institutional aspects are consequential and tribute to the agricultural sector development. Also, the current rise of market opportunities at the local and international levels is a driver to support them. This study aimed to analyze socio-economic and governance components to understand the pdo Cocoa Arriba (Theobroma cacao) chain sustainability performance and bring forward potential strategies. Principal Components Analysis was introduced to contribute with relevant insights.The framework applied accounts with a revision of primary and support activities. The investigation clustered pre-production, production, and post-production tiers. Also, it executed the food chain mapping and identification of chain actors. Results stated several viable long-term strategies. Examples of those strategies are the enhancement of national regulation to assist chain actors and the stimulus of young producers and associations empowerment. The main research contribution is the application of governance mechanisms to assess the chain performance comprehensively. Based on the results, our recommendation is to incorporate new indicators to analyze the environmental and institutional components profoundly.
Il "dialogo sociale" nella costruzione asimmetrica dell'Unione Europea, tra battute d'arresto e rilanci
Authors: Michieli Andrea
Published: September 2020

Nel processo di integrazione europea l'avanzamento del "dialogo sociale" e la tutela dei diritti sociali sono sempre andati di pari passo. L'armonizzazione "nel progresso" sostenuta dalle parti sociali europee si è però arrestata con la gestione della crisi del 2008 e con le scelte comunitarie di governance economica. Il con-tributo, dopo aver ripercorso la genesi della concertazione sociale europea e il suo attuale stato di paralisi, mette in rilevo la necessità di un nuovo corso del "dialo-go sociale" che, con l'approvazione de Pilastro europeo dei diritti sociali, possa ridefinire l'equilibrio tra libertà e diritti nel mercato unico europeo
The consequence of traditional understanding of psyche and nature for the environmental and psychological problems
Authors: Kawai Toshio
Published: September 2020

From a historical perspective, psyche is seen to have changed from an open system in the premodern time to a closed one in modern time. This has brought a separation of nature and psyche; Science has the nature as object, psychology only copes with the inside of person. The process of internalization seems to be changing in the postmodern time. The inner life is shown to all over the world via internet, twitter, etc. Psyche is again becoming an open system. To have some hints on contemporary situation Japanese culture and history are compared. There still remains premodern understanding of psyche and nature in Japan. But Japanese art such as gardening and ikebana show that a unique process of internalization has happened by way of making exquisite miniatures of nature. There is a growing tendency in the postmodern age not to decide and to be involved. This can be called a "contingent" attitude (Agamben). According to the modern understanding of psyche, psyche and environment are separated. But the postmodern situation makes again a world possible where everything is connected. This may be a chance to contribute to global and environmental problems from the psychotherapy

Authors: Caccamo Gabriella , Termini Fabrizia
Published: September 2020

Il lavoro parla dei Gruppi Balint (con cenni sulla teorizzazione psicoanalitica di Balint), metodo di formazione utilizzato dalla sezione milanese dell'AIPA per la formazione in gruppo degli allievi in training. Si accenna al pensiero di Bion relativo alle dinamiche nei piccoli gruppi e alla teoria degli assunti di base, che ogni conduttore di gruppo deve avere ben presente. Si stabilisce infine un punto di incontro tra l'attenzione di Balint agli aspetti relazionali del rapporto terapeuta/pa­zien­te e il pensiero di Jung incentrato sulla metafora alchemica per rappresentare il processo che coinvolge insieme analista e paziente.
Attaccamento e bullismo: un confronto tra bulli, vittime, bulli-vittime e non-coinvolti in età scolare
Authors: Di Pentima Lorenza , Ramelli Sara
Published: September 2020

Scopo del presente studio è stato analizzare il fenomeno del bullismo secondo la prospettiva dell'attaccamento, ponendo a confronto i bulli, i bulli-vittima, le vittime e i non-coinvolti nei modelli mentali e nei comportamenti socio-emozionali (in particolare aggressività, evitamento dell'interazione, manifestazioni di ansia e depressione). Hanno partecipato allo studio 365 bambini, 208 maschi (57%) e 157 femmine (43%), di 5 scuole di Roma, di età compresa tra 8 e 11 anni (M = 9.28, DS = 0.81). Gli strumenti impiegati sono stati: Nomina dei Pari (Menesini, 2003), per individuare i ruoli di bullo, vittima, bullo-vittima e non coinvolto, Separation Anxiety Test (Attili, 2001) per la misura dei modelli mentali dell'attaccamento e Social Emo-tional Dimension Scale (Ianes, & Savelli, 1994) per la valutazione dei comportamenti socio-emozionali. Dai risultati emerge che, nel confronto con i non-coinvolti, i bulli mostrano più attaccamenti ambivalenti ed evitanti, li dove le vittime e i bulli-vittima mostrano per lo più modelli mentali di tipo ambivalente. Inoltre i bulli, i bulli-vittima e le vittime presentano più alti livelli di aggressività, di evitamento delle interazioni con i pari e di comportamenti inappropriati.
La gestione della relazione terapeutica in un'ottica cognitivo-costruttivista ed evolutiva
Authors: Lambruschi Furio
Published: September 2020

Nel presente articolo la relazione psicoterapeutica è considerata in una prospettiva costruttivista, evolutiva e interpersonale. Si propone un modello a tre assi del funzionamento umano, che rende conto delle diverse possibili organizzazioni del sé e delle loro possibili declinazioni su livelli diversi di funzionamento metacognitivo. Per ogni asse vengono quindi descritti i diversi possibili criteri di osservazione e di utilizzo clinico della relazione terapeutica. Su un primo asse viene valorizzata la consapevolezza nel terapeuta riguardo allo stile di regolazione emotiva e alla organizzazione dei sistemi di memoria proprio e del paziente in vista di una loro adeguata sintonizzazione e complementarietà nelle diverse fasi del processo psicoterapeutico. Sul secondo asse, si sottolinea come il lavoro di riparazione delle inevitabili rotture dell'alleanza di lavoro vada costantemente riportato agli specifici temi dolorosi e ai significati personali caratteristici del paziente da un lato e del terapeuta dall'altro. Sul terzo asse, vengono evidenziati i caratteristici modelli interpersonali dei pazienti con forti limitazioni nelle funzioni metacognitive insieme ad alcune attenzioni da porre nella gestione dei relativi cicli interpersonali.
La relazione terapeutica nella terapia metacognitiva interpersonale
Authors: Salvatore Giampaolo , Ottavi Paolo , Popolo Raffaele , Dimaggio Giancarlo
Published: September 2020

La ricerca empirica mostra un'associazione stretta tra buon funzionamento della relazione terapeutica e buon esito del trattamento. L'attenzione alla relazione terapeutica è uno dei fulcri della terapia metacognitiva interpersonale (TMI). In questo articolo, dopo aver sintetizzato gli aspetti fondamentali del modello, descriveremo come in TMI il lavoro sulla relazione si intrecci con l'utilizzo di tecniche esperienziali quali immaginazione guidata e role playing, finalizzate a promuovere nel paziente la comprensione del suo mondo interno e il cambiamento clinico. Forniremo una serie di esemplificazioni cliniche al fine di descrivere come la relazione sia nel contempo: 1) strumento per favorire l'accesso ai contenuti psicologici rilevanti; 2) strumento per favorire un'esperienza emozionale correttiva; per esempio, in molti casi l'utilizzo di una tecnica esperienziale mette il paziente in condizione di contattare parti di sé libere dalla patologia, e di sperimentare la relazione terapeutica come fonte di speranza e sostegno all'autonomia; 3) oggetto di intervento in caso di rotture della relazione, anche nei casi in cui tali rotture sono la conseguenza dell'utilizzo di tecniche esperienziali. Nel complesso, mostreremo come il processo terapeutico in TMI sia mosso dalla capacità del terapeuta di muoversi agilmente tra l'utilizzo di tecniche volte a esplorazione e cambiamento, e focus sulla relazione

Od synchronizacji do wizualizacji. Prezentacja dziejów na kartach średniowiecznych kronik uniwersalnych
Authors: Soszyński Jacek
Published: September 2020

The article deals with the development of graphical systems of presenting history in universal chronicles on the instances of Eusebius of Caesarea and Jerome in late antiquity, Martinus Polonus in the thirteenth century, and Werner Rolevinck at the break of the Middle Ages and the Renaissance. With the translation of the Eusebius’ Chronikoi Canones performed by Jerome, the synchronistic table was introduced into the Western historiographical tradition. This form of presenting history became firmly rooted in Latin chronicles, in particular within the genre of universal chronicles, which endeavoured to recount the history of mankind from Adam to the Final Judgement, and were very popular well into the early modern period. The author argues that the chronicles of Eusebius/Jerome and Martinus Polonus simply utilized synchronicity, in their pursuit to produce encyclopaedic works, aimed at the scholarly reader. In their intention, the synchronistic table was a technical means for a more effective presentation of past events. With Werner Rolevinck the case was different. The layout introduced by him was no longer asynchronistic table, but an attempt at visualizing history, with very little attention paid to precise dating of various events and persons. He constructed his complicated graphical system for religious purposes, to contemplate the magnificence of God’s creation, in accordance with the ideas of the devotio moderna, and destined his work for a much wider audience than scholars.
Nieznane średniowieczne zabytki języka niemieckiego z kolekcji Ludwika Zalewskiego w zbiorach Biblioteki Narodowej
Authors: Kaliszuk Jerzy
Published: September 2020

Among others, the Polish National Library possess a collection (MS 8098 IV) encompassing parchment fragments extracted from bookbindings, which contain German texts. This collection was acquired from the family of the deceased bibliophile from Lublin, Father Ludwik Zalewski. The collection consists of eleven parchment leaves, six of which form three bifolia, the other five being small fragments. The collection is known to historians, chiefly due to two of the bifolia, which contain fragments of an Old Saxon translation of  the Psalms (Altsächsiche Psalmen). The rest of the fragments, dated chiefly by the author to the fourteenth century, are also of interest. J. Kaliszuk identifies them as belonging to: Der Welsche Gast by Thomasin von Zerklaere, the Christherre-Chronik and the Livländische Reimchronik. The author also demonstrates that this collection was put together by L. Zalewski, hence there is no possibility of tracing the provenance of individual fragments. The article is supplemented by two appendices, the first with codicological descriptions of the complete collection, and the second containing an edition of the letter from Stanisław Tomkowicz, an art historian from Cracow, to Ludwik Zalewski, written in 1916, concerning the fragments in question.
Z grabieży Katarzyny ocalone szczątki... czyli udział Biblioteki Uniwersyteckiej w Warszawie w rewindykacji księgozbiorów na mocy traktatu ryskiego
Authors: Pietrzkiewicz Dorota
Published: September 2020

The article deals with the works of the Special Mixed Commission formed as a result of the Polish-Soviet Riga Peace Treaty, which functioned during the years 1921–1937. The issue of the Polish cultural goods was brought forward by the Polish side already during the initial phases of the peace negotiations. The Poles considerd their cultural claims as one of the major problems to be resolved. Poland demanded the return of various archival, library and museum objects. These demands were met to a certain degree. Detailed issues were to be decided by the Mixed Commission. Since the beginning of its functioning, the Commission was aided by the Warsaw University Library, which received the manuscripts, incunabula, and old prints, belonging to the King Stanislaw Poniatowski collections, returned by the Russians. Subsequently, the materials of other than university provenance were transferred in three stages to the National Library (in 1930, 1931, 1936), and to other institutions, among them the Central Archives of Historical Records in Warsaw. The recovery of Polish cultural goods, decreed by the Riga Peace Treaty, because of its far reaching scope, was unprecedented in history. As aresult, Poland regained her great library collections, which were forcibly taken out of the country and allocated to the fonds of the Russian book repositories during the 18th and the 19th centuries. But the process was neither easy nor quick. The Soviet side returned the materials kept at Leningrad – 1764 Latin, French and Italian manuscripts, 1308 incunabula, and 250 historical charters and acts – not earlier than in April 1936. The efforts related to the return of these particular monuments are treated by the author.

Street vended fruits cause food borne illnesses in developing countries. This study was carried out to determine the microbiological safety of some street vended fruits sold in Yenagoa metropolis of Bayelsa State, Nigeria. Freshly cut ready-to-eat vended pawpaw, watermelon and pineapple were analysed for possible contamination with bacteria and fungi using standard microbiological techniques. A total of (17) samples: (5) Pawpaw, (6) Watermelon and (6) Pineapple were obtained from three (3) different local markets in Yenagoa metropolis, namely; Tombia, Opolo and Swali markets. Bacterial count ranged from 1.3x105 to 2.4x106cfu/ml for pineapple; 1.9x105 to 8.1x106cfu/ml for watermelon and 3.7x106 to 7.6x106cfu/ml for pawpaw samples. The highest bacterial count was obtained in watermelon from Opolo market, while the highest fungal count was recorded in pawpaw retailed at Opolo market. Microbial isolates were Bacillus sp, Escherichia coli, Salmonella sp, Staphylococcus sp, Klebsiella spp, Citrobacter spp, Proteus spp, Enterobacter spp, Mucor spp and Saccharomyces cerevisiae. There were 58.8% occurrence of Escherichia coli and Staphylococcus spp and occurred most. Bacillus spp and Klebsiella spp had 47.1% occurrence and closely followed by Staphylococcus aureus 41.2%, while Proteus spp had the least 5.9% occurrence. The result obtained may be responsible for the prevalence of Escherichia coli and Staphylococcus spp in Yenagoa metropolis. The presence of these organisms in these ready-to-eat retailed fruits analysed is a reflection of unwholesomeness and gross contamination of the fruits and therefore make the fruits unsafe for human consumption; hence the need for proper microbiological safety analysis of fruits for human consumption.
Policing Ethics: Context Bangladesh

Published: September 2020

The police are one of the most powerful and important forces for any country. The main task of the police is to install a sense of security in the ordinary citizens and to protect their life and property when they are in danger. Bangladeshi Police have a glorious past with tremendous achievement. Especially in our great liberation war in 1971, they played an important role in achieving our liberation. Eliminating terrorism & militancy and others several operation that leads with the risk of their life. But there are still a lot of accusations against the police force. Like- abusing of power, Misconducting with the people, Committing crossfire defying the high-court order, Wearing white dress when they move to  detain criminals, Arresting without warrant, and many other including Bribery, Extortion, Trading Drug and Yaba, Playing partisan role, keeping Bad association, Filing case against deceased man, Charging sheet against the infant who has not been born yet,  Enforcing disappearance, Suppressing the freedom of express,  Violating Human rights, Doing anti-social activities such as rape, forcible extortion, drinking alcohol, etc. are the real scenario of Bangladesh Police. Policing ethics or related unethical behaviors, in particular, are shaped by both societal perceptions and organizational socialization of the police personnel on how authority should be exercised, as well as the latter's relationship with the socio-political and economic structures overtime. This paper proposes to explain the role of police as the main law enforcement agency in any democratic country.  An Attempt has been made to bring different perspectives of ethics which comprises views of Aristotle, Machiavelli, Immanuel Kant, J S Mill and John Rawls. The paper focuses on police Ethics. Police ethics’ reflects the society and the regulations that shape the policing system. Discuss the results and analysis of the consequences of moral degradation caused by the Police. Explore the police brutality because of the lack of Ethics to highlight the public's attitude towards police. The ethical standards and the code of conduct Police practitioners should actually abide by is an ongoing debate.
Child Marriage in Bangladesh: Policy and Ethics
Authors: Arnab Ahnaf Tahmid , Siraj Md. Sanwar
Published: September 2020

Bangladesh is a Muslim-majority society with more than 163 million people. Most Bangladeshis hold the ideals of Islamic norms and values which is manifest in all sorts of socio-cultural behaviour. In reference to such values, the tradition of legitimizing child marriage in Bangladesh is the issue that needs to be addressed in a holistic yet rigorous approach. Currently Bangladesh ranks 4th in the world and 1st in Asia in terms of child marriage. Recently the Child Marriage Restraint Act 1929 has been abolished and it has been replaced by the Act of 2017 preserving article 2 of the previous statute, the legal age for marriage for a boy 21 and for a girl 18. This Act adds article 19 which legalizes minors (below 18 years of age) to be married off with the consent of the parents/guardians at the presence of a magistrate under “special circumstances” deemed with securing the best interest for them. The law artfully coincides with the Muslim Marriage Law which allows participants of 15 years and above to get legally married and as such contradicts the international law and the Act of 2017 itself. In the West intimate relationships including extra-marital cohabitation before reaching 18 years of age are culturally accepted. In contrast, such extra-marital and intimate relationships are strictly prohibited in Muslim-majority societies, which are dearly adhered in Bangladeshi Muslim culture. This study examines how the religious cultural and socio-economic realities influence child marriage practice in Bangladesh. Along with secondary documents, we interviewed 22 individuals including the Deputy Commissioner, the District Women and Children Affairs Officer, elected Union Parishad Chairman and Members, Social Workers, married couples and their parents/guardians at Manikganj district. In addition, we also conducted a mass survey with 62 randomly selected participants, and a voluntary online survey where the opinion of another 53 young students were collected to find broad opinion. We also collected stories of how marriages take place at the rural, urban and sub-urban areas in Bangladesh. The study has revealed that Bangladeshis does not support marriage at early ages but socio-economic reality often pushes poor into getting their children married at early ages. Many view that the special provision may encourage child marriage in the country. This study suggests that the government of Bangladesh should redefine public policy in regard to finding a middle ground between Islamic ethics and international values by exploring isomorphic mimicry and other socio-culturally accepted measures with a view to abolishing child marriage successfully.

Published: September 2020

Background and Objectives Acute low-tone hearing loss (ALHL) is gaining attention as an independent disease identity with close association with endolymphatic hydrops and early stage Meniere’s disease (MD). This study aims to compare patients of ALHL with patients exhibiting low-tone hearing loss and ear fullness without vertigo in various audio-vestibular assessments and in progression to overt MD.Subjects and Method A total of 249 patients with low-tone hearing loss with ear fullness without vertigo was enrolled in this study. Of these patients, 58 patients met criteria for ALHL, which was defined as having an average hearing loss of ≥30 dB at 125, 250, and 500 Hz and ≤20 dB at 2, 4, and 8 kHz. Demographics, electrocochleography (ECoG) abnormality, rate of hearing improvement, vestibular functions, and progression to MD were analyzed.Results An average low-tone hearing loss of ALHL patients was 42.8 dB, which recovered to 18.9 dB following a combined treatment of diuretics and oral steroid therapy. The hearing recovery rate of this group was 87.9% and the ECoG abnormality ratio was 42.5%. Also, 15.5% of ALHL patients eventually progressed to MD.Conclusion This study described demographics and characteristics of ALHL, demonstrating a successful response to the combined treatment of diuretics and oral steroid. Also, this report demonstrated a close relationship between the degree of low-tone hearing loss and ECoG abnormality and observed the progression to MD in ALHL patients. These data can be usefully applied in clinical setting to explain clinical outcomes of ALHL.
Epithelial-Mesenchymal Transition in Head and Neck Cancer
Authors: Park Gi Cheol
Published: September 2020

Metastasis is one of the most important factors in the prognosis and choice of treatment strategy of patients with head and neck squamous cell carcinoma (HNSCC). In order for dissemination to take effect, tumor cells must segregate themselves from their primary tumor site and migrate into the blood or lymphatic vessels. To detach from the primary tumor, cells have to disrupt cell-cell adhesion, remodel of the cytoskeleton, change in cell-matrix adhesion and finally return to their original condition. This temporary and reversible process is known as the epithelial-mesenchymal transition (EMT). EMT is a dynamic cellular process in which epithelial cells acquire mesenchymal features and suggested to play an important role during cancer invasion and metastasis. With the recent explosion of knowledge on EMT in carcinogenesis, EMT has become an interesting target for anticancer therapy. This review article first highlights at the biochemical changes that take place around the cell membrane called cadherin switching during EMT and looks at the current literature on EMT in HNSCC. Understanding the mechanism of EMT will provide insight to the metastasis of HNSCC and may lead to the development of novel anti-cancer therapeutics.

Testes de média e análises de correlações (simples, canônicas e trilha) permitem a identificação de caracteres correlacionados com o rendimento de grãos. Devido à pouca disponibilidade de trabalhos que relatam os níveis de correlação de plantas de soja com os espaçamentos entre linhas e por demandas dos produtores rurais,  objetivou-se com o trabalho identificar a influência do espaçamento entre linhas de genótipos de soja sobre os níveis de rendimento, através de metodologias estatísticas de teste de média, regressões e correlações. O estudo foi conduzido sob condições de campo na Fazenda Quero-Quero, no município de Chapadão do Céu, Goiás, Brasil. O delineamento experimental foi em blocos ao acaso com 8 tratamentos, correspondentes a 2 genótipos de soja (Desafio e M7739), submetidos a 4 espaçamentos entre linhas (22.5, 45, 67.5 e 90 cm) em 4 repetições.  Foram quantificados 8 caracteres para explicar o rendimento de grãos. As análises foram realizadas no programa estatísticos R Core Team. Os caracteres apresentaram interação entre as fontes de variação e significância para com os efeitos principais. Correlações foram descritas nas variáveis canônicas e mensuradas seus efeitos diretos e indiretos. Ao término do trabalho, concluiu-se que o espaçamento entre linhas e o fator genético alteram as médias de rendimento da cultura de soja, e que o rendimento dos genótipos de soja desafio e M7739 está correlacionado com o estande, altura de planta e legumes com dois grãos.

Published: September 2020

A inoculação com bactérias do gênero Bradyrhizobium, ocasiona na rizosfera a formação estruturas especializadas na fixação biológica de nitrogênio, sendo descartada a aplicação na cultura da soja, uma vez que a relação simbiótica consegue suprir suas necessidades. O objetivo do trabalho foi avaliar a influência da inoculação bem como de níveis de nitrogênio em cobertura no crescimento, desenvolvimento e produtividade da soja. O experimento foi realizado na área experimental da Universidade Estadual de Mato Grosso do Sul – Unidade Universitária de Aquidauana. O delineamento experimental foi em blocos casualizados em esquema fatorial 4x4, com quatro repetições. Os tratamentos foram constituídos pela combinação entre inoculantes (Bradyrhizobium japonicum; Azospirillum brasilense; B. japonicum + A. brasilense; Controle sem inoculação) e quatro níveis de nitrogênio em cobertura na soja (0; 50; 100; 150 kg ha-1). A inoculação foi realizada antes da semeadura, já a aplicação do nitrogênio foi realizada no estádio V8, para tal, utilizou-se sulfato de amônio como fonte. Foram avaliados: população final de plantas, altura da planta, altura de inserção da primeira vagem, diâmetro do caule, número de vagens por planta, número de grãos por vagem, produtividade de grãos, massa de 1000 grãos. A inoculação de sementes de soja usando isoladamente ou em conjunto não interfere no desenvolvimento e produtividade de grãos da cultura da soja, assim o uso de nitrogênio mineral em cobertura é dispensável, pois não reflete em incrementos na produtividade de grãos da soja.

Seed rain is an ecological process and its functional attributes are essential for maintaining the dynamics of natural regeneration. The objective of this research was to evaluate the spatial variation of the seed rain in a toposequence of a Seasonal Deciduous Forest defined by three elevations: (Base 512 m; Slope: 534 m and Top: 559 m). 15 collectors of 1 m² were installed at each elevation level. Data were collected monthly from September / 2017 to February / 2019. The seeds were classified according to the dispersion syndrome, habit and size. Non-Metric Multidimensional Scaling (NMDS) was used to verify the variation in species composition and distribution. We identified 20,217 propagules, belonging to 65 species and 30 families, in addition to 4 morphospecies, which represents 449 seeds / m². The families with the highest species richness were Fabaceae, Sapindaceae and Euphorbiaceae. Of the 65 species sampled, 71% were arboreal. Zoochoric species predominated (78%) and very small seeds corresponded to 53% of the sample. We demonstrate that, on a small spatial scale, the relief represents an important source of heterogeneity in the vegetation component, since the topographic gradient influenced the composition and distribution of the functional attributes of the seed rain.

O presente estudo de cunho quantitativo, teve como objetivo analisar a suplementação nutricional e a sua relação com a saúde e composição corporal de praticantes de musculação em uma academia da cidade de Castanhal-PA, bem como avaliar as mudanças antropométricas ocasionadas em decorrência da reeducação alimentar dos sujeitos pesquisados. Participaram deste estudo 20 indivíduos, sendo 10 homens e 10 mulheres, com idade entre 20 e 35 anos. Foram aplicados dois questionários recordatários, um sobre como era a alimentação do indivíduo antes de iniciar seu período de treinamento e um sobre sua alimentação após três meses de treinamento, e um terceiro questionário relacionado à suplementação alimentar. Os resultados apontaram melhoras significativas na reeducação alimentar dos sujeitos. Quanto a suplementação alimentar, os suplementos mais consumidos foram os ricos em proteínas (60% dos homens e 83% das mulheres) e aminoácidos ramificados, sendo estes consumidos por 30% dos homens e 67% das mulheres. A maior parte dos suplementos foi consumida por iniciativa própria para 38% dos homens. Os benefícios observados e relatados com a suplementação foram o ganho de força e de massa muscular - em que 50% dos homens e 60% das mulheres apresentaram esses ganhos. Sendo que também uma minoria da amostra relatou alguns efeitos colaterais que foram associados ao suplemento alimentar. Mudanças positivas na antropometria também foram observadas. Conclui-se que existe uma forte relação entre exercícios físicos e mudanças de hábitos alimentares, e a associação com uso de suplementos alimentares.

The presence of toxic aluminum in the soil and N deficiency are one of the main causes of degradation of cultivated pastures, mainly of the Urochloa genus. The use of agricultural gypsum for restoring soil fertility is one of the ways to recover the productive capacity of degraded areas. Given the above, the work aims to assess pasture recovery with the application of agricultural gypsum associated with nitrogen fertilization. The experimental design was randomized blocks in a 3x4 factorial arrangement, that is, absence of nitrogen, 50 kg ha-1 in the form of ammonium nitrate and 50 kg ha-1 urea, interacting with four doses of agricultural gypsum, namely: 0 ; 750; 1500 and 3000 kg ha-1 and with four replications, totaling 48 plots. The use of urea as a source of N resulted in a higher plant height (PH) when compared to the use of ammonium nitrate, representing a relative increase of approximately 12% in relation to the control. Dose of 1730.8 kg ha-1 of agricultural gypsum resulted in a maximum production of 4.97 t ha-1 of dry pasture. The linear interaction of the use of ammonium nitrate with gypsum doses shows an extremely interesting synergistic potential with this source. For dry mass of culms (CDM), the use of urea had a PMTE of 1730.8 kg ha-1 of agricultural gypsum resulting in 2.38 t ha-1. The culms dry mass of (CDM) represented 47.9% of the total dry mass of the pasture.

Periodontite Apical Crônica é a inflamação e destruição do periodonto apical resultante de irritantes polimicrobianos do sistema de canais radiculares. Há evidências na literatura que associam a Diabetes Mellitus tipo II com a maior prevalência de PAC, maior tamanho de lesões periapicais, maior probabilidade de infecções periapicais assintomáticas e comprometimento na reparação periapical. Polpas dentárias de pacientes com diabetes tendem a apresentar circulação colateral prejudicada, resposta imunológica diminuída, aumento do risco de contrair infecção, além de tendência ocasional para necrose pulpar causada por isquemia. Este estudo pretende contribuir para um maior esclarecimento da relação entre o descontrole metabólico do paciente e a infecção crônica periapical. Assim, procurou-se revisar a relação entre a Periodontite Apical Crônica e a Diabetes Mellitus tipo II e analisar a prevalência microbiológica nas infecções endodônticas. A literatura revisada aponta para uma relação de susceptibilidade transversal entre a Periodontite Apical Crônica e a Diabetes Mellitus tipo II o que aumenta o índice de falha na resposta ao tratamento endodôntico.

Introdução: indivíduos com amputação de membro inferior apresentam importantes mudanças biomecânicas, com consequente aumento na probabibiliade de desenvolver algum transtorno musculoesquelético. Objetivo: verificar a prevalência de dor lombar (DL) em amputados de membro inferior atendidos em um centro de reabilitação da região metropolitana de Porto Alegre/RS. Métodos: estudo transversal com 37 amputados de membro inferior com idades de 20 a 87 anos. O instrumento de coleta de dados foi um questionário relacionado a presença e características de dor lombar, aspectos demográficos e socioeconômicos, avaliação do equilíbrio estático e dinâmico, presença ou não de encurtamento muscular de iliopsoas e medidas antropométricas. Resultados: a prevalência de DL foi de 46% (IC95%: 29,1% - 62,8%) e os principais fatores associados foram o tempo de amputação e encurtamento do iliopsoas. Conclusão: verificou-se uma alta prevalência de DL entre os amputados, sendo associada ao tempo de amputação e com a presença de encurtamento de iliopsoas, reforçando a importância destes aspectos para o planejamento de ações preventivas e de assistência aos amputados.

O estudo objetivou analisar dados epidemiológicos no período de 2001 a 2017 da hanseníase no Maranhão, doença infectocontagiosa crônica causada pelo bacilo Mycobacterium Leprae, que afeta a pele e nervos, para assim suscitar o debate sobre a situação epidemiológica da doença no estado do Maranhão, Brasil. Os dados analisados foram as taxas de detecção de novos casos na população geral e de casos com grau II de incapacidade no maranhão. Através de regressão linear pelo método de Prais-Winsten foi possível identificar uma tendência decrescente da taxa de detecção anual na população geral e tendência estacionária da taxa de detecção com grau II de incapacidade. Contudo, a taxa de detecção de novos casos em 2017 foi de 44,49 casos por 100.000 habitantes, considerada alta, classificando o maranhão como hiperendêmico. O estado apresentou taxas decrescentes de detecção em população geral (APC de -2,76; IC95% -3,50;-2,01)  e em doentes com grau II de incapacidade física (APC: -0,07; IC95%:-0,15;-0,00). Dessa forma, observa-se que houve avanços no combate à hanseníase no estado, porém, sugere-se melhores estudos sobre a confiabilidade dos dados e maior esforço no combate à doença, haja vista que ainda apresenta altas taxas no Maranhão.
