Screening for Adverse Childhood Experiences in Children: A Systematic Review
Authors: Loveday Sarah , Hall Teresa , Constable Leanne , Paton Kate , Sanci Lena , Goldfeld Sharon , Hiscock Harriet
Published: January 2022

CONTEXT

Adverse childhood experiences (ACEs) are associated with increased risk of poor mental health outcomes. Although there is interest in screening for ACEs for early identification and intervention, it is not known whether screening improves outcomes for children.

OBJECTIVE

To systematically review whether screening for ACEs in children leads to an increase in (1) identification of ACEs, (2) referrals to services, (3) increased uptake of services, and (4) improved mental health outcomes for children and parents.

DATA SOURCES

Ovid Medline, PsycINFO, CINAHL, and Center for Clinical and Translational Research electronic databases were searched between 2009 and 2021.

STUDY SELECTION

Studies were included if researchers screened for current ACEs in children aged 0 to 12 years and they had a control comparison.

DATA EXTRACTION

Information was extracted, including study characteristics, sample demographics, screening tool characteristics, referral rates to services, uptake rates, and mental health outcomes.

RESULTS

A total of 5816 articles were screened, with 4 articles meeting inclusion criteria. Screening for ACEs increases identification of adversity and may increase referrals to services. There are limited data about whether this leads to an increase in referral uptake by families. There are no reported data addressing mental health outcomes.

LIMITATIONS

There are few published control trials of moderate quality.

CONCLUSIONS

There is limited evidence that screening for ACEs improves identification of childhood adversity and may improve referrals. If we are to realize the hypothesized benefits of ACEs screening on child and parent mental health, it is essential to understand the barriers for families taking up referrals.

Published: January 2022

Tracking mass through harsh environments requires surrogate particles that withstand the event and endure until sampling. Silica-covered quantum dots have been shown to withstand a range of environmental pHs from months to years; in this work they are shown to endure in anticipated local environments. Two methods of particle synthesis were employed to produce luminescent silica with particle diameters 0.1–4 μm. These tracer particles scale for mass production, tolerate harsh environments, and endure in debris. They could be deployed in places such as chemical explosions, industrial processes, geologic test beds, oil and gas fields, nuclear reactors, and geothermal plants to track mass under harsh conditions.

Neolithic Bow Case from Lenk, Schnidejoch
Authors: Junkmanns Jürgen , Klügl Johanna , Di Pietro Giovanna , Hafner Albert
Published: January 2022

The find of a yet unknown type of birch bark container in the site of Schnidejoch (Bernese Alps, Switzerland) was a surprise, for in all the wetland or lakeshore sites of Europe no parallels to this unique object are known to date. First, when only a small part was discovered, it was supposed to have been part of an arrow quiver. However, with the final appearance of the ca. 170 cm long container, it needed a new interpretation. The yew bow found at the same site, 160.5 cm long, would fit perfectly inside. Two silex arrowheads found in the bottom confirm an association with archery. The find could be identified as the first Neolithic bow case.
An Application of Ground-Penetrating Radar at a Greater Yellowstone Area Ice Patch
Authors: Ackermann Brandon , Lee Craig M. , McWethy David , Chellman Nathan , McConnell Joe
Published: January 2022

Ice patches are an irreplaceable archive of past events. With atypical melting now occurring around the world, it is important to be able to quantify and interpret the potential of what remains in areas of archaeological interest. A ground-penetrating radar (GPR) survey was conducted at an archaeologically productive ice patch in the Greater Yellowstone Area to identify sediment layers in which archaeological materials may be present. Numerous reflective surfaces were observed and interpreted as being organic-rich layers called lags. GPR did not reveal all lag surfaces that were easily identifiable in an ice core that was collected concurrently at the same ice patch. 400 MHz and 900 MHz antennas were used in the survey, but neither fully revealed the basal profile of the ice patch. This is likely the result of the short time-window in which the data were collected, as opposed to attenuation of the radar waves deep in the ice. Future applications of the technology are explored.

Authors: Azida Mafriha , Fitri Alifa Nur
Published: January 2022

Ecological criticism is mostly understood as the study of literature with an ecological perspective. The novel "Laut Bercerita" by Leila Salikha Chudori builds a relationship between women and the preservation of nature and the environment. This novel is a literary genre that deconstructs ecofeminism or green literature. The purpose of this study was to increase knowledge about the relationship between literary works and the thought of the ecofeminism movement in the novel "Laut Bercerita". This research method uses qualitative content analysis. The results show that the importance of conserving nature and risking their property, life, and family to achieve prosperity and justice for the community. Human dependence on nature must also be harmonized with the maintenance and preservation of nature. The novel “Laut Bercerita” offers a new perspective on the relationship between humans and nature. The preservation of nature and the environment is shown by the struggle of Kinan and his friends

Published: January 2022

Abstract In July 2020, during a survey carried out in a small farm located in Laranjal Paulista, state of São Paulo (Brazil), more than 20 white pitahaya plants [Hylocereus undatus (Haw.) Britton and Rose (syn. Selenicereus undatus (Haw.) D.R. Hunt] were found with stunting symptoms and showing chlorotic-yellowish stems, some of them already decaying. Roots exhibited numerous galls, indicating Meloidogyne sp. infection. Nematodes were recovered from 200 cm³ and 7 g of roots: 1.7 Meloidogyne juveniles (J2) per cm³ of soil and 954 eggs + J2 per g of roots were found. The perineal pattern of 10 females pointed to M. incognita. Additionally, esterase phenotype was obtained through isozyme electrophoresis, using another 10 females, which identified M. incognita. To our knowledge, this is the first report of M. incognita infesting pitahaya plants (Hylocereus spp.) and, based on our results, M. incognita could be a potential threat to the crop.

Published: January 2022

Abstract Advances in production systems always aim at finding alternatives to improve crop productivity. One of the recent practices adopted in commercial banana and plantain plantations refers to the application of liquid fertilizers in bunches in order to increase productivity. This research aimed at verifying whether the use of biofertilizers based on pure vinasse or associated with other chemical fertilizers would provide morphophysiological changes in fruits or increase the productivity of ‘Terra Maranhão’ plantain cultivars. In order to carry out this project, a randomized block design with 6 treatments and 3 replicates was set up in a commercial crop and the postharvest production and quality characteristics of ‘Terra Maranhão’ plantain fruits were evaluated. The results showed that the morphophysiological characteristics of freshly harvested fruits that impact productivity such as the fruit weight and bunch weight were affected by treatments, as the postharvest characteristics of ripe fruits were little affected by the application of fertilizers in bunches, except for the SST content. It could be concluded that the crop yield increased significantly by 17% when using mixture of vinasse, potassium chloride and urea; however, this treatment caused significant reduction of 1.3 ºBrix compared to control.

Published: January 2022

Abstract Only few studies have focus on animals that received Pilocarpine (Pilo) and did not develop behavioral status epilepticus (SE) and, whether they may become epileptic in the model’s chronic phase. Previews works observed mossy fiber sprouting in the hippocampus of Non-SE (NSE) rats, while others observed spontaneous and recurrent seizures (SRS) 6 - 8 months after animals received Pilo. It is known that neuronal excitability is influenced by female hormones, as well as, the occurrence of SE in castrated and non-castrated female rats. However, it is not known whether females that received Pilo and did not show SE, may have SRS. The aim of this work was to investigate whether castrated and non-castrated female rats that did not show behavioral SE after Pilo, will develop SRS in the following one-year. For that, animals received 360 mg/kg of Pilo and were video monitored for 12 months. SE females from castrated and non-castrated groups became epileptic since the first month after drug injection. Epileptic behaviors were identified watching video monitoring recordings in the fast speed. Castrated and Non-castrated NSE animals showed behaviors resembling seizures described by Racine Scale stages 1 - 3. Motor alterations showed by NSE groups could be observed only when recordings were analyzed in slow speed. In addition, behavioral manifestations as, rhythmic head movements, sudden head movements, whole body movements and immobility were also observed in both, SE and NSE groups. We concluded that NSE female rats may have become epileptic. Adding to it, slow speed analysis of motor alterations was essential for the observation of NSE findings, which suggests that possibly many motor alterations have been underestimated in epilepsy experimental research.

Abstract Under salt stress conditions, plant growth is reduced due to osmotic, nutritional and oxidative imbalance. However, salicylic acid acts in the mitigation of this abiotic stress by promoting an increase in growth, photosynthesis, nitrogen metabolism, synthesis of osmoregulators and antioxidant enzymes. In this context, the objective was to evaluate the effect of salicylic acid doses on the growth and physiological changes of eggplant seedlings under salt stress. The experiment was conducted in a greenhouse, where the treatments were distributed in randomized blocks using a central composite matrix Box with five levels of electrical conductivity of irrigation water (CEw) (0.50; 1.08; 2.50; 3.92 and 4.50 dS m-1), associated with five doses of salicylic acid (SA) (0.00; 0.22; 0.75; 1.28 and 1.50 mM), with four repetitions and each plot composed of three plants. At 40 days after sowing, plant height, stem diameter, number of leaves, leaf area, electrolyte leakage, relative water content, and total dry mass were determined. ECw and SA application influenced the growth and physiological changes of eggplant seedlings. Increasing the ECw reduced growth in the absence of SA. Membrane damage with the use of SA remained stable up to 3.9 dS m-1 of ECw. The relative water content independent of the CEw increased with 1.0 mM of SA. The use of SA at the concentration of 1.0 mM mitigated the deleterious effect of salinity on seedling growth up to 2.50 dS m-1 of ECw.
And Mintzberg discovered Brazil: the internationalization of an executive master’s program
Authors: Teixeira Ana Christina Celano , Wanderley Sergio , Moraes Ana Beatriz , Sá Bianca
Published: January 2022

Abstract This research analyzes the International Master’s Program for Managers (IMPM) internationalization process through a partnership established with a Brazilian Higher Education Institution. IMPM was conceived by Henry Mintzberg in 1996 as a program strong enough to challenge traditional American MBA programs since Mintzberg proposes that “managers not MBAs” should prevail. A critical perspective is adopted here to investigate whether the IMPM privileges an Anglo-Saxon point of view or not. We used a qualitative approach involving ninety-six in-depth interviews with faculty members and directors from both institutions responsible for establishing this partnership and carrying out the Brazilian module of the program, eight of which are addressed in this paper. Professor Henry Mintzberg was one of the interviewees. The findings show that despite all the efforts to preserve local culture, an Anglo-Saxon logic prevails, and there is an imbalance between the initial proposition and the results. There are a lot of unexplored issues to solve considering this framework, and future studies should consider and propose the recognition of the local production of knowledge and cultural diversity as key elements for the success of international partnerships.
Proposição de uma teoria substantiva para o processo de acreditação hospitalar: o modelo “comprometimento com o cuidado”

Published: January 2022

Resumo Este estudo apresenta uma teoria substantiva que se propõe a explicar como interagem e que fatores influenciam os elementos envolvidos no processo de implantação, manutenção e evolução da acreditação hospitalar. A pesquisa foi realizada entre os anos de 2015 e 2017, por meio do case do Hospital Regional Público da Transamazônica (HRPT), localizado em Altamira (PA), região Norte do Brasil. Entrevistas, análise documental e observação participante ocorreram de forma longitudinal num período de 24 meses, espaço de tempo que compreendeu a manutenção do nível 2 da acreditação hospitalar no HRPT, bem como a evolução ao nível 3 e sua manutenção. Sob um viés construtivista e qualitativo, o levantamento de dados foi dividido em 5 rodadas, conforme as diretrizes da grounded theory na vertente de Charmaz, e envolveu 56 participantes. O modelo proposto, denominado “comprometimento com o cuidado”, se mostrou uma alternativa integradora e sistêmica à compreensão de como ocorre a acreditação hospitalar na organização estudada. Sua estrutura é constituída por 3 categorias centrais - “a forma como trabalhamos”, “acreditação como instrumento de ação” e “amor à causa” -, 1 categoria de suporte - “desenvolvimento dos profissionais de saúde” - e 2 categorias de resultado - “excelência nos resultados” e “cuidado centrado no paciente”. Esses achados dialogaram com o pensamento complexo e o estudo das instituições.
WHEN STAKEHOLDER THEORY MEETS JUSTIFICATION THEORY: AN INTERSECTION PROPOSAL
Authors: GÓES HELNA ALMEIDA DE ARAUJO , REIS GERMANO GLUFKE , ABIB GUSTAVO
Published: January 2022

Abstract We discuss an interplay between two theories by addressing the question: In what ways can the Justification theory (JT) complement the Stakeholder theory (ST)? While ST provides an insight on the importance of creating value for stakeholders without resorting to tradeoffs, it does not address how several stakeholders employ justifications to achieve their goals, nor does it explore the analytical thinking on how organizations and their stakeholders account for and negotiate behaviors during disputes. The JT provides a framework that interprets social interactions and tensions by considering that actors’ decisions and actions are contextualized within organizational reality. Several studies that apply the JT framework in the context of organizations do so by directly or indirectly analyzing stakeholders. Hence, this essay sheds light on how such an intersection may help to comprehend the phenomena related to disputes. The study offers tools and contributes to understanding managerial practices for stakeholders identification and engagement since, to the best of our knowledge, there is a research gap regarding the intersection between JT and ST.

Um estudo pós-colonial, com o uso da semiótica, sobre capas de livros clássicos editados no Brasil e nos Estados Unidos
Authors: QUEIROZ MARIANA LUZ EIRAS , HEMAIS MARCUS WILCOX , PESSÔA LUÍS ALEXANDRE
Published: January 2022

Resumo O controle exercido pelos países do Norte global sobre as nações que foram colonizadas se reflete nos contextos culturais e ideológicos dessas sociedades. Um desses reflexos é encontrado em capas de livros clássicos, que são o objeto desta pesquisa, a qual pretende analisar como são representados o Norte e o Sul globais no projeto gráfico de capas de livros clássicos brasileiros e estadunidenses. Para alcançar esse objetivo, foi realizada uma análise semiótica dos planos do conteúdo e da expressão em 304 capas de livros, com base na teoria formulada por Jean-Marie Floch. No conjunto de obras estudadas, buscou-se verificar elementos geopolíticos no projeto gráfico de capas, em que nível os elementos estadunidenses são reforçados nas capas editadas no Brasil e como os itens brasileiros aparecem nas capas editadas nos Estados Unidos. Para tanto, utilizou-se a teoria de Edward Said sobre orientalismo como base para essa verificação, observando-se que os títulos brasileiros, quando editados nos Estados Unidos, são carregados de estereótipos criados pelo Ocidente, enquanto os livros estadunidenses, quando editados no Brasil, refletem as mesmas representações encontradas nas capas daquele país.
The impact of generation diversity on trust within companies
Authors: Migueles Carmen Pires , Zanini Marco Tulio Fundão , Carvalho Juliana , Filardi Fernando
Published: January 2022

Abstract This paper investigates the causes of generational differences at work and their impact on the propensity to trust. We treated propensity to trust as a proxy for social capital, enhancing cooperation and efficiency. We assessed trust variations in a sample of five companies using combined qualitative and quantitative methods to investigate possible differences in the levels of trust among generational cohorts. We conducted 36 in depth-interviews and 24 focus groups and collected 894 valid questionnaires. The qualitative analysis suggests that differences among generations are related to the experience of time and time-flow and uncertainty and vulnerability throughout one’s lifetime. The results confirm that perceived vulnerability negatively affects the predisposition to trust.

Published: January 2022

Abstract Based on the sociology of translation, we studied the extreme case of the new coronavirus to explore the role of non-humans in relational processes. We seek to understand how leaders of three countries tried, in a translation process, to take the voice of the new coronavirus and how the virus resisted the imposition of roles by the human actors of the study. Through the analysis of the leaders’ statements, interviews, and social media posts, we suggested the process of disinteressement, in four movements. As a contribution, we show how the non-human actant (i) is active in terms of participation in the translation process, and (ii) resisted the roles imposed.
“Trabalho sujo”, significado, sentido e identidade: proposição de análise integrada e perspectivas de pesquisas
Authors: Pereira Jefferson Rodrigues , Paiva Kely César Martins de , Irigaray Hélio Arthur Reis
Published: January 2022

Resumo O presente estudo foi desenvolvido com o objetivo de refletir sobre as possíveis relações entre significado, sentido e identidade do trabalho, considerando as ambiguidades e paradoxos que permeiam certas ocupações na sociedade brasileira. Para tal, foi desenvolvido um ensaio teórico considerando perspectivas acerca do “trabalho sujo”, significados e sentidos do trabalho e identidade(s). A abordagem analítica adotada permitiu identificar que a marginalização de determinadas ocupações em vez de outras possui em seu cerne aspectos muito mais complexos do que a natureza do trabalho per si. Compreender, portanto, esse fenômeno requer esforços mais robustos e mais aprofundados relativamente aos até então apresentados na literatura de identidade, significados e sentidos do trabalho e “trabalho sujo”. A tese em foco é de que há algo mais sobre ocupações com baixo prestígio e altos níveis de sujidade, que afeta negativamente o bem-estar dos trabalhadores, do que simplesmente o estigma e as manchas impressas sobre os “trabalhadores sujos”.

Published: January 2022

RESUMO: Discutiremos os desdobramentos psicopatológicos na zona arcaica da subjetividade quando a identificação projetiva perde sua dimensão de comunicação primitiva, assumindo um caráter radical de evacuação e prejudicando a rêverie materna. Estudaremos as experiências precoces do psiquismo englobadas na parte bebê do self, fundamentais aos processos de simbolização primária. Suas falhas se manifestam na clínica através de intensos sofrimentos capitaneados por angústias primitivas, como as de abandono e de separação, que acarretam respostas radicais, tais como a fragmentação e a despersonalização. Apresentaremos um fragmento clínico para ilustrar a forma de desorganização psíquica própria às falhas na parte bebê do self.
HUMOR, SINTHOMA E LEVEZA
Authors: D’Agord Marta Regina de Leão
Published: January 2022

RESUMO: Este trabalho propõe paralelos entre a interpretação freudiana do humor e o conceito de sinthoma em Lacan. A experimentação joyceana com a escrita interessou à Psicanálise, chegando a produzir efeitos, como é o caso da diferenciação lacaniana entre symptôme e sinthoma. A cultura judaica do leste europeu e a perplexidade com o desmoronamento de um império forneciam material para o humor kafkiano e para a teoria freudiana do humor. Com Kafka e Joyce, a literatura inventa formas literárias de leveza que interessam à investigação psicanalítica.

Published: January 2022

RESUMO O Parque Estadual da Cantareira, no bioma da Mata Atlântica, foi criado a partir da desapropriação de fazendas de café para proteção de mananciais para a cidade de São Paulo em 1877. Desde então, poucas atividades humanas ocorreram em seu interior. Aqui, comparamos a composição e o estágio sucessional de diferentes fragmentos de floresta próximos (<0,5 km um do outro). Foram levantados 0,6 ha, divididos em três áreas de 0,2 ha cada, com árvores atingindo PAP ≥ 15 cm, sendo amostradas, identificadas e medidos o diâmetro e a altura. O estágio sucessional das espécies foi determinado e um perfil de cada área foi desenhado em escala. Um total de 1.020 indivíduos pertencentes a 45 famílias e 115 espécies foi amostrado. Os fragmentos variaram em número de indivíduos (300-399 indivíduos), famílias (N = 26-32) e espécies (N = 54-68), altura e estágios sucessionais, indicando alta heterogeneidade dentro de uma floresta contínua, desde os estágios sucessionais maduros até os iniciais. Essas descobertas têm implicações para o manejo da conservação e os serviços ecossistêmicos fornecidos por eles.

ABSTRACT Arterial hypertension is a worldwide public health problem and the search for new medicines is one of the biggest challenges for the treatment of this pathology. Secondary metabolites of plants exhibit pharmacological properties of great phyto therapeutic interest. Cerrado is one of the largest biomes in Brazil and research with Cerrado plants as therapeutic resources is of growing interest. Our objective was to compile data regarding the Cerrado plants that already have some of their active compounds described and may potentially be used to treat arterial hypertension. We concluded that flavonoids, tannins, steroids and saponins exhibit important properties to low blood pressure. Thus, the species from Cerrado Brazilian such as pau-paraíba (Simarouba versicolor), pau-santo (Kielmeyera coriacea), abiu-do-cerrado (Pouteria torta), guarandi (Calophyllum brasiliense), bacaba (Oenocarpus bacaba), puçá-amarelo (Mouriri elliptica), fava-de-anta (Dimorphandramollis), murici (Byrsonima crassifolia) and cereja-do-cerrado (Eugenia calycina) are strong candidates for future herbal studies in this field.

Microcirculation during surgery
Authors: Nam Karam , Jeon Yunseok
Published: January 2022

Throughout the long history of surgery, there has been great advancement in the hemodynamic management of surgical patients. Traditionally, hemodynamic management has focused on macrocirculatory monitoring and intervention to maintain appropriate oxygen delivery. However, even after optimization of macro-hemodynamic parameters, microcirculatory dysfunction, which is related to higher postoperative complications, occurs in some patients. Although the clinical significance of microcirculatory dysfunction has been well reported, little is known about interventions to recover microcirculation and prevent microcirculatory dysfunction. This may be at least partly caused by the fact that the feasibility of monitoring tools to evaluate microcirculation is still insufficient for use in routine clinical practice. However, considering recent advancements in these research fields, with more popular use of microcirculation monitoring and more clinical trials, clinicians may better understand and manage microcirculation in surgical patients in the future. In this review, we describe currently available methods for microcirculatory evaluation. The current knowledge on the clinical relevance of microcirculatory alterations has been summarized based on previous studies in various clinical settings. In the latter part, pharmacological and clinical interventions to improve or restore microcirculation are also presented.

Resonant modes of motion, manifested as a significant increase in the oscillation amplitude of the spatial angle of attack, can result in the failure of the CubeSat mission. This paper is concerned with the study of the resonant motion modes of aerodynamically stabilized CubeSat nanosatellites in low circular orbits with small inertia and mass asymmetry. In contrast to axisymmetric bodies of rotation, resonances in CubeSat nanosatellites can be caused not only by small asymmetry, but they also arise due to the form factor of the rectangular parallelepiped. Formulas have been obtained to determine the critical values of the nanosatellite longitudinal angular velocity at which the conditions for the emergence of resonant motion modes are fulfilled. An approach is proposed to prevent possible resonances for CubeSat nanosatellites.

Published: January 2022

The past decade has been marked by an explosive growth in the number of missions with the use of small spacecraft weighing only about tens of kilograms, including CubeSats that are currently widely employed in various applications. For a scientific paper, it is no longer feasible to enumerate and properly analyze the accomplished missions as well as those under development and being planned: information changes so quickly that perhaps only websites with inline renovations can keep track of all the changes in this market. Near-Earth missions of CubeSats increasingly become the prerogative of engineers and production managers. Nowadays, even factories are built to mass-produce small spacecraft. However, interplanetary small-spacecraft missions stand apart because the technologies used to develop large spacecraft for interplanetary missions are not fully applicable to small spacecraft. The same is true of the bal-listic aspects of such missions. This is primarily due to the low energy capability of small spacecraft for maneuvering and transmitting signals over long distanc-es. The other equally important aspects are their self-sufficiency, navigation support, and radiation resistance in outer space. From the standpoint of the sci-entific novelty of the problems that spacecraft have to face and the fundamen-tals of ballistic implementation, it is interplanetary missions that attract atten-tion of researchers. This paper discusses the opportunities for interplanetary transportation of small spacecraft and formulates the problems that need to be solved in the near future.

Çözülebilir bağlantı şekillerinden olan cıvatalı bağlantıların, sitemlerde verimli ve emniyetli bir şekilde kullanılması için farklı parametrelere göre yük altındaki davranışlarının anlaşılması son derece önemlidir. Bu çalışmada, cıvata ile birleştirilmiş tek tesirli bindirme bağlantılarında delik toleransının ve cıvata sıkma torkunun bağlantı dayanımına etkisi teorik gerilme ve sonlu elemanlar analizleriyle araştırılmıştır. Teorik çalışma, elastisite teorisi denge denklemleri kullanılarak yapılmıştır. Sonlu elemanlar analizleri ise ANSYS programı kullanılark lineer-elastik gerilme ve hasar analizi şeklinde gerçekleştirilmiştir. Çalışmanın amacı, delik toleransı ve sıkma torku değişiminin bağlantının yük taşıma kapasitesinde oluşturduğu etkileri özellikle plaka dayanımı açısından araştırmaktır. Yapılan çalışma sonucunda, delik toleransının artması plaka dayanımını düşürmüştür. Cıvata torkunun artması ise plaka dayanımını arttırmıştır. Delik toleransı ve cıvata torku değişiminin bağlantı dayanımına etkileri birlikte değerlendirildiğinde, cıvata torkunun daha etkin bir parametre olduğu anlaşılmıştır. Yapılan çalışmada seçilen delik tolerans değerleri arasındaki farklar çok fazla olmasına karşın, bu tolerans farklarının dayanıma etkileri genellikle % 10 değerinin altında olmuştur. Cıvata torkunun plaka dayanımına etkisi ise % 37 değerine kadar çıkmıştır. Çok düşük tolerans aralıklarıyla yapılan imalatların maliyetlerinin oldukça yüksek olduğu düşünüldüğünde, elde edilen sonuçlara göre toleransları normal seviyelerde tutup, buna karşın cıvata torkunun arttırılmasının daha doğru bir tasarım olduğu sonucuna varılmıştır.

İş dünyasında Ar-Ge ve inovasyon çıktılarının önemi her geçen artmaktadır. Ar-Ge ve inovasyon faaliyetlerinin teknoloji ve strateji ile uyumu sürdürülebilir başarının önemli güvencelerinden biridir. Bu aşamada Ar-Ge ve inovasyon faaliyetlerini yönlendiren ve yaygın bir şekilde kullanılan teknoloji yol haritaları ilk akla gelmektedir. Teknoloji yol haritaları, teknoloji gelişimi ve değişimini ilgili diğer katmanlarla (ürünler, hizmetler, pazar vb.) ilişkilendiren ve karar vermeye yardımcı olan araçlardır. Geçerli bir teknoloji yol haritası elde edebilmek için ögeler arası ilişkilerin doğru tanımlanması gerekir. Bu çalışma teknoloji yol haritası ögeleri arasındaki ilişkiler için bir infografik önermektedir. Öge ikililerinin ilişki derecesi ve ilişkilerin önem derecesi aralıklı tip-2 bulanık sistemler (IT2FS) kullanılarak değerlendirilmektedir. Bu değerlendirme sonuçlarını kullanarak oluşturulan infografik ile teknoloji yol haritaları zenginleştirilmektedir. Önerilen sürecin daha iyi anlaşılması için üç boyutlu (3D) yazıcı teknolojileri uygulama örneği sunulmuştur. Bu şekilde zenginleştirilmiş teknoloji yol haritalarının özellikle büyük ölçekli sistemlerde strateji oluşturma sürecine ve teknoloji yönetim faaliyetlerine katkı sağlayacağı düşünülmektedir.

Aktif deprem bölgelerinde yaygın kullanılan süneklik düzeyi yüksek çelik merkezi çaprazlı çerçeveler (MÇÇ) için güncel Amerikan, Kanada ve Türkiye sismik tasarım yönetmeliklerinde tasvir edilen kapasite tasarımı yaklaşımına göre, MÇÇ’lerdeki kolon ve kirişler, çaprazların doğrusal olmayan çevrimsel davranışını göz önüne alan, iki farklı yapısal analiz gözetilerek tasarlanmaktadır. Bu yapısal analiz hallerinde göz önüne alınan mekanizma durumu ve tüm katlardaki çapraz elemanların aynı anda aynı sınır duruma ulaştığı kabulü, bahsedilen kapasite tasarımı yaklaşımının en belirleyici özelliklerini oluşturmaktadır. Bu çalışmanın amacı, literatürde iyi bilinen az sayıdaki çalışmaya dayanan bu kabullerin geçerliliğini incelemek ve tasarım alışkanlıklarını değiştirmeden, geleneksel yaklaşıma alternatif, dengeli bir boyutlandırma yöntemi önermektir. MÇÇ’ler için öncü yönetmeliklerce gözetilen kapasite tasarımı yaklaşımını irdelemek amacıyla, iki farklı çapraz düzeni ve boyutlandırma yaklaşımı kullanılarak boyutlandırılan MÇÇ’lerin doğrusal olmayan davranışları statik ve dinamik yükler etkisinde incelenmiştir. Sonuçlar, en büyük ve kalıcı göreli kat ötelemesi taleplerinin yanı sıra, çaprazlarda oluşan süneklik talepleri bakımından karşılaştırılarak tartışılmıştır. Çalışma sonucunda, güncel kapasite tasarımı yaklaşımında göz önüne alınan mekanizma durumunun ve kabullerin deprem etkisinde gerçekleşme ihtimalinin düşük olduğu; önerilen dengeli boyutlandırma yaklaşımının ise geleneksel yaklaşıma göre %8’lik bir tonaj artışıyla sismik taleplerde ciddi düşüşler sağladığı görülmüştür.
Application of Genetically Modified Organism (GMO) crop technology and its implications in modern agriculture
Authors: Werkissa Yali
Published: January 2022

Genetic modification entails incorporating DNA into an organism’s genome as well as putting new DNA into plant cells in order to create a genetically modified plant. Chemicals are poured into plants to improve product sizes and productivity in genetically modified organisms (GMOs), a type of clinical farming. The goal of genetic modification is to provide enhanced features to plants by altering their genetic makeup. This is done by inserting a novel gene or gene into the genome of a plant. Flavr Savr tomatoes were the first genetically modified plants, and they were modified to delay the ripening process, preventing tenderness and rot. Complete crop production increased significantly after the introduction of GM crops at some point during the generation; some of these increases may be due to GM technologies and crop protection advances that have been made possible, despite the fact that GM crops adopted so far are not crop yields. GMOs gain humanity when they are utilized for purposes like improving the availability and quality of food and hospital therapy, as well as contributing to a cleaner environment. If employed correctly, they have the potential to improve the economy without inflicting more harm than good, as well as gain from its ability to alleviate hunger and sickness around the world. However, the full potential of GMOs cannot be identified without thorough research and attention to the dangers associated with each new GMO on a particular scenario basis. Improved resistance to disease and pests can be achieved by genetic modification. It may enable the production of more nutritious staple plants that provide key micronutrients that are frequently lacking in the diets of poor people. As a result, the purpose of this review was to assess the deployment of genetically engineered crops and their effects on modern agriculture progress.

Exosomes are membrane vesicles that constitute a potential mode of intercellular communication. Although the scope of its role is still being discussed, the release of exosomes by tumor cells suggests their participation in pathological situations and its study will surely drive to new therapeutic and diagnostic strategies. It is therefore important to be able to localize and identify these kinds of particles in transmission electron microscopy images. This preliminary work shows how a recent deep-learning algorithm available online can be applied to exosomes images to localize all the instances of the objects of interest, in any scale and several backgrounds.

Background: The demographic aging of the Algerian population increases the risk of some age-related pathologies, including dementia. It is one of the most significant public health problems. The prevalence of dementia and risk factors has not been fully investigated in Algeria. This study aims to improve the knowledge of dementia in Algiers by determining its risk factors, allowing to enrich its epidemiology and social aspects. Methods: A cross-sectional, door-to-door study in the Department of Sidi M’Hamed in Algiers “Algeria», conducted in general population, was carried out between June 2012 and August 2014. The clinical diagnosis of dementia was made according to the Diagnostic and Statistical Manual of Mental Disorders,4th Edition (DSM-IV) criteria. Possible or probable cases of Alzheimer’s Disease (AD), Mixed Dementia (MD), Vascular Dementia (VD), Frontotemporal Dementia (FTD), Parkinson’s Dementia (PD), and other dementias were identified using standard criteria. Sociodemographic characteristics, lifestyle and the pathological history were recorded. Results: 3896 subjects aged 60 years and over participated in the study. Among them, 192 had dementia. Factors strongly associated with dementia in the department of Sidi M’Hamed were advanced age, living alone, widowhood, low cultural level, family history of dementia, high blood pressure and stroke (p<10−6). Conclusion: Greater age, low social raise, low level of education and vascular risk factors (stroke and high blood pressure) increase the risk of suffering from dementia. Other more extensive studies should be conducted, both in rural and urban areas of Algeria, in order to consider comprehensive management solutions and prevention approaches adapted to our context.
