Authors: Pirzad Alireza , Mamyandi Mahmood Mazlomi , Khalilzadeh Razieh
Published: February 2021

The deficiency and toxicity of boron may lead to noticeable yield reduction and quality loss of sugar beet. To evaluate the effects of nano-boron on the root yield and quality of sugar beet, factorial experiment was conducted based on a randomized complete block design with three replications at Urmia University. Treatments were spraying of nano-boron oxide (0, 2, 3 and 4 g L-1) at different growth stages (20, 40, 60, 80 and 100% of ground cover). Increasing levels of boron up to 3 g L-1 resulted in the highest SPAD (Soil Plant Analysis Development) value, leaf number and relative water content. With optimal leaf area (86.47 cm2), the highest yields of root, sugar, white sugar, and technological sugar (144.53, 28.23, 26.19 and 25.32 t ha-1) were determined in the treatment of 4 g L-1 boron at 40% of ground covered. Increasing nano-boron level under different growth stages increased sugar and white sugar contents, on contrary impurities (Na, K and α-amino-N) loss and molasses sugar percentage were decreased. More than 3 g L-1 nano-boron exhibited the highest values of purity. Application of 3 g L-1 boron at 40% of ground cover increased sugar and white sugar contents by 12.45 and 18.72%, respectively.

Authors: Sim Carrie Siew Fang , Cheow Yuen Lin , Ng Si Ling , Ting Adeline Su Yien
Published: February 2021

Five metal-tolerant endophytic isolates (Bipolaris sp. LF7, Diaporthe miriciae LF9, Trichoderma asperellum LF11, Phomopsis asparagi LF15, Saccharicola bicolor LF22), with known metal-tolerance attributes and biocontrol activities against Ganoderma boninense, were tested for growth-promoting activities independent of (in vitro) and associated with plants (height, weight, root mass and stem circumference) (in vivo). Results revealed that metal-tolerant endophytes did not significantly render benefit to host plants as plant growth was compromised by the presence of metals. Lower production of indole-acetic acid (0.74-21.77 μg mL-1), siderophores (8.82-90.26%), and deaminase activities of 1-aminocyclopropane carboxylic acid (3.00-69.2 μmol mg protein-1 hr-1) were observed.
Quantum certainty mechanics

Published: February 2021

Quantum certainty mechanics is a theory for measuring the position and momentum of a particle. Mathematically proven certainty principle from uncertainty principle, which is basically one of the most important formulas of quantum certainty mechanics theory. The principle of uncertainty can be proved by the principle of certainty and why uncertainty comes can also be proved. The principle of certainty can be proved from the theory of relativity And in the uncertainty principle equation, the principle of certainty can be proved by fulfilling the conditions of the principle of certainty by multiplying the uncertain constant with the certain values of momentum-position and energy-time. The principle of certainty proves that the calculation of θ π/2 between the particle and the wave involved in the particle leads to uncertainty. But calculating with θ=0 does not bring uncertainty. Quantum certainty mechanics has been established by combining Newtonian mechanics, relativity theory and quantum mechanics. Quantum entanglement can be explained by protecting the principle of conservation of energy.

Emotional development is increasingly understood as a crisis in the development of children. From the early development period, babies show a sense of security in their families if their needs are met by their environment. Babies will explore through touch and rasal. The learning process at this time will influence the development at a later stage. Early age is also called the golden development stage (golden ege). At this stage most brain cells function as controllers of each activity. By paying attention and understanding the emotions of children, can help teachers accelerate the learning process that is meaningful and permanent. The ability of early childhood to manage emotions is part of the maturation of emotional development of children in the transition from preoperative to concrete operational period. The ability of early childhood to manage their own emotions can be seen from the dimension of children's ability to use their emotions positive.

Published: February 2021

We show for the first time that the neuropeptide orexin modulates pupillary light response, a non-image-forming visual function, in mice of either sex. Intravitreal injection of the orexin receptor (OXR) antagonist TCS1102 and orexin-A reduced and enhanced pupillary constriction in response to light, respectively. Orexin-A activated OX1Rs on M2-type intrinsically photosensitive retinal ganglion cells (M2 cells), and caused membrane depolarization of these cells by modulating inward rectifier potassium channels and nonselective cation channels, thus resulting in an increase in intrinsic excitability. The increased intrinsic excitability could account for the orexin-A-evoked increase in spontaneous discharges and light-induced spiking rates of M2 cells, leading to an intensification of pupillary constriction. Orexin-A did not alter the light response of M1 cells, which could be because of no or weak expression of OX1Rs on them, as revealed by RNAscopein situhybridization. In sum, orexin-A is likely to decrease the pupil size of mice by influencing M2 cells, thereby improving visual performance in awake mice via enhancing the focal depth of the eye's refractive system.

SIGNIFICANCE STATEMENTThis study reveals the role of the neuropeptide orexin in mouse pupillary light response, a non-image-forming visual function. Intravitreal orexin-A administration intensifies light-induced pupillary constriction via increasing the excitability of M2 intrinsically photosensitive retinal ganglion cells by activating the orexin receptor subtype OX1R. Modulation of inward rectifier potassium channels and nonselective cation channels were both involved in the ionic mechanisms underlying such intensification. Orexin could improve visual performance in awake mice by reducing the pupil size and thereby enhancing the focal depth of the eye's refractive system.
Intrinsic Neuronal Activity during Migration Controls the Recruitment of Specific Interneuron Subtypes in the Postnatal Mouse Olfactory Bulb
Authors: Bugeon Stéphane , Haubold Clara , Ryzynski Alexandre , Cremer Harold , Platel Jean-Claude
Published: February 2021

Neuronal activity has been identified as a key regulator of neuronal network development, but the impact of activity on migration and terminal positioning of interneuron subtypes is poorly understood. The absence of early subpopulation markers and the presence of intermingled migratory and postmigratory neurons make the developing cerebral cortex a difficult model to answer these questions. Postnatal neurogenesis in the subventricular zone (SVZ) offers a more accessible and compartmentalized model. Neural stem cells regionalized along the border of the lateral ventricle produce two main subtypes of neural progenitors, granule cells and periglomerular neurons that migrate tangentially in the rostral migratory stream (RMS) before migrating radially in the olfactory bulb (OB) layers. Here, we used targeted postnatal electroporation to compare the migration of these two populations in male and female mice. We do not observe any obvious differences regarding the mode of tangential or radial migration between these two subtypes. However, we find a striking increase of intrinsic calcium activity in granule cell precursors (GC-Ps) when they switch from tangential to radial migration. By decreasing neuronal excitability in GC-Ps, we find that neuronal activity has little effect on migration but is required for normal positioning and survival of GC-Ps in the OB layers. Strikingly, decreasing activity of periglomerular neuron precursors (PGN-Ps) did not impact their positioning or survival. Altogether these findings suggest that neuronal excitability plays a subtype specific role during the late stage of migration of postnatally born OB interneurons.

SIGNIFICANCE STATEMENTWhile neuronal activity is a critical factor regulating different aspects of neurogenesis, it has been challenging to study its role during the migration of different neuronal subpopulations. Here, we use postnatal targeted electroporation to label and manipulate the two main olfactory bulb (OB) interneuron subpopulations during their migration: granule cell and periglomerular neuron precursors (PGN-Ps). We find a very striking increase of calcium activity only in granule cell precursors (GC-Ps) when they switch from tangential to radial migration. Interestingly, blocking activity in GC-Ps affected mainly their positioning and survival while PGN-Ps were not affected. These results suggest that neuronal activity is required specifically for the recruitment of GC-Ps in the OB layers.

Polarity, expression of degree and negation: the vernacular form caraças
Authors: Pinto Clara
Published: February 2021

This paper presents the vernacular form caraças which, in European Portuguese (EP) is associated to multiple contexts, differents from its use as a feminine common noun. The data I will present shows that caraças behaves as a polarity item, without referential interpretation. On the one hand, caraçasbehaves as a minimizer, a subtype of Negative Polarity Item (NPI), being associated to the lowest point of a scale of value. On the other hand, it also behaves as a Positive Polarity Item (PPI), expressing maximal degrees, therefore being a maximizer. The fact that caraças occurs simultaneously as a NPI and a PPI could indicate we are in the presence of a bipolar element, as described by van der Wouden (1997). Nevertheless, data suggests that there are two distinct items caraças, one of them being a NPI and the other a PPI.The form caraças is also associated to other contexts of use, namely as a metalinguistic negation marker and in evaluative constructions such as N-of-an-N constructions. We also find it functioning as an interjection in exclamative sentences.Although the feminine common noun caraça (augmentative of cara ‘face’) remains in the lexicon as synonym of mask, the polarity item caraças does not result from a process of grammaticalization of the common noun, as documented for other polarity items. In this paper I will put forth the idea that caraças, in its masculine singular form, appeared as an euphemistic variant of caralho ‘dick’, a highly offensive taboo term, used to designate the masculine sexual organ.

Published: February 2021

El aprovechamiento resinero se está posicionando en los últimos años en el noroeste peninsular como una posibilidad para generar ingresos complementarios en los pinares atlánticos productores de madera. No obstante, las condiciones del monte gallego (atomización de la propiedad, pendiente, presencia de matorral y altas densidades) implican rendimientos y costes diferentes a los pinares que se resinan fundamentalmente en Castilla y León. Por lo tanto, es necesario conocer tanto las producciones de miera o resina como los rendimientos que supone su extracción en estas circunstancias. En el presente estudio se analizan las producciones para el método de resinación de pica de corteza, para pinares próximos a la edad de corta y cuyo aprovechamiento principal es la madera. Se estudió la producción para una cara de 12 cm de ancho, que es lo habitual en España, para una cara de 16 cm, para dos caras de 12 cm y para dos caras de 16 cm. También se analizaron los tiempos y rendimientos para el sistema más productor, que fue el de dos caras de 16 cm.

POST-SOCIALIST LABOR FORCE AS A COMMON-POOL RESOURCE
Authors: Penov Ivan
Published: February 2021

The article is devoted to the challenges of the labour market in the post-socialist period. It discusses the issues related to the physical properties of the post-socialists labour force and the social and legal framework in which it operates. Labor traditionally is considered to be a private good in the economic literature, possessing the properties of high excludability and rivalry. We argue that in the post-socialist period, labour looks more like a common pool resource system rather than a private good. In the absence of appropriate legal and social structures, such a system is likely to operate under the conditions of open access. In the long run, this could lead to a depletion of this resource. We argue that looking at labour in the frame of common pool resource, first we can justify better the use of the traditional instruments for intervention at the labour market, and second, this could help to develop a more efficient system for preserving and development of the labour force in the long run.
ORGANIZATIONS FOR TOURISM REGION MANAGEMENT IN BULGARIA – TRENDS AND CHALLENGES
Authors: Bozhinova Mariyana , Georgieva Kristina
Published: February 2021

Destination management organizations (DMOs) are well-established management structures in the international tourism practice. In Bulgaria’s legislation, they are defined as organizations for tourism region management (OTRMs). The aim of this paper is to outline the expected trends and the possible challenges for the development of the organizations for tourism region management in Bulgaria. The research is based on methods such as system approach, deduction, induction, questionnaire-based surveys, etc. The main findings of the survey are as follows: there are 7 OTRMs listed in the registry of the Ministry of Tourism and two of the tourism regions have not yet registered such organizations; many people employed in the sector of tourism are still not aware of the functions of these OTRMs; the OTRMs are essential for development and promotion of regional and a national tourism products. The overall conclusion is that OTRMs and their functions are still not well-established in Bulgaria although they could be a key factor for a successful repositioning of the country as a tourism destination, development of competitive tourism products, and sustainable development of tourism.

Scientists around the world are focusing their interest on the use of probiotics in honey bees as an alternative method of prophylaxis against causative agents of both American and European foulbrood. In our study we tested inhibitory activity against Paenibacillus larvae and the biofilm formation activity by various lactic acid bacteria isolated from honey bee guts or fresh pollen samples in the presence of different sugars added to the cultivation media. In addition, we tested the probiotic effect of a newly selected Apilactobacillus kunkeei V18 in an in situ experiment in bee colonies. We found antibacterial activity against P. larvae in four isolates. Biofilm formation activity of varying intensity was noted in six of the seven isolates in the presence of different sugars. The strongest biofilm formation (OD570 ≥ 1) was noted in A. kunkeei V18 in the presence of fructose; moreover, this isolate strongly inhibited the growth of P. larvae under laboratory conditions. Inhibition of P. larvae and Melissococcus plutonius by A. kunkeei V18 in situ was confirmed in a pilot study.
Bachelor’s and Master’s degrees: One and the same thing? A case study of implementing the degree system in Romania
Authors: Torotcoi Simona
Published: February 2021

The adoption of a system based on cycles has been one of the core action lines in the Bologna Process. It represents the base for promoting student mobility, employability, and international competitiveness. The implementation of the degree-cycle system – conditioned by the achievement of other policy objectives (i.e. ECTS) – started hot debates on multiple levels including on the relevance of different study stages, or the extent to which the curricular emphasis would differ between the two levels. After almost two decades since the reform has been introduced, rather than looking at the state of implementation, current research should focus on how the reform has been implemented and what are its effects. By using the Romanian case as an illustration of the situation in Central and Eastern Europe (CEE), this paper aims to answer the following questions: to what extent have the intentions and expectations linked to the introduction of a tiered structure of degrees have been fulfilled and what are some the (unintended) effects of such reforms? Based on a series of interviews done in November 2017 with academic staff, student representatives and decision-makers from Romania, this paper presents an analysis of the deliberate intentions and expectations of the introduction of the degree structure. The conclusions show that issues related to (1) financing; (2) quality (3) access and participation; (4) content and curricula (5) career path and opportunities after graduation are the main implications of the implementation of the degree-cycle system.

Published: February 2021

Combined anatomical and functional evaluation of coronary artery disease (CAD) using computed tomography (CT) has recently emerged as an accurate, robust, and non-invasive tool for the evaluation of ischemic heart disease. Cardiac CT has become a one-stop-shop imaging modality that allows the simultaneous depiction, characterization, and quantification of coronary atherosclerosis and the assessment of myocardial ischemia. Advancements in scanner technology (improvements in spatial and temporal resolution, dual-energy imaging, wide detector panels) and the implementation of iterative reconstruction algorithms enables the detection of myocardial ischemia in both qualitative and quantitative fashion using low-dose scanning protocols. The addition of CT perfusion (CTP) to standard coronary CT angiography is a reliable tool to improve diagnostic accuracy. CTP using static first-pass imaging enables qualitative assessment of the myocardial tissue, whereas dynamic perfusion imaging can also provide quantitative information on myocardial blood flow. Myocardial tissue assessment by CTP holds the potential to refine risk in stable chest pain or microvascular dysfunction. CTP can aid the detection of residual ischemia after coronary intervention. Comprehensive evaluation of CAD using CTP might therefore improve the selection of patients for aggressive secondary prevention therapy or coronary revascularization with high diagnostic certainty. In addition, prognostic information provided by perfusion CT imaging could improve patient outcomes by quantifying the ischemic burden of the left ventricle. The current review focuses on the clinical value of myocardial perfusion imaging by CT, current status of CTP imaging and the use of myocardial CTP in various patient populations for the diagnosis of ischemic heart disease.

O Papel do Jornalismo Sindical para identificação do indivíduo através do retrato do grupo; da construção da consciência coletiva à formação de leitores
Authors: Amaral Adriana C. A. do
Published: February 2021

Eduardo Galeano, poeta e taxativamente, declarou que a utopia serve para que possamos caminhar. Nesses tempos onde a relação dialógica parece nos fazer voltar a um passado sombrio e quando a pela perda de direitos nos faz retroceder à era da exploração do homem pelo homem, conhecer o próprio lugar é fundamental, como cantou Belchior em seus versos tristes e tão reais da canção Conheço o meu lugar, este artigo versa sobre uma prática jornalística pouco reconhecida, consequência de suas próprias mazelas, mas que se destina e tem a oportunidade de dialogar com milhões de trabalhadores: o jornalismo sindical. Refletindo sobre a “palavramundo” de Paulo Freire, a célebre frase “Trabalhadores do Mundo Uni-vos”, de Marx e Engels, pontuado no conceito da precarização do trabalho abordado por Ricardo Antunes e nas reflexões de Ladislau Douwbor sobre o mundo laboral, não pretende encontrar respostas, mas instigar pensares sobre como chegamos onde estamos e como fazer do trabalhador, que somos todos nós, protagonistas de suas vidas. Reconhecer o papel do jornalismo sindical como ferramenta fundamental para ecoar o “lugar de fala” do trabalhador através dainformação direcionada, que instigue a reflexão e a reverberação. Vivenciamos hoje a Revolução 4.0 que deveria nos proporcionar o direito ao ócio, fazendo a robotização um serviço à Pessoa Humana, mas ao contrário não apenas trabalha por nós como escreve e parece pensar como as pessoas humanas. “O principal motor das transformações é seguramente a revolução tecnológica que vivemos. Essa revolução atual não é mais de infra-estrutura, como a ferrovia ou o telégrafo, ou de máquinas, como o automóvel ou o torno, mas de sistemas de organização do conhecimento (Douwbor, 2001) e, nesse contexto, é preciso refletir e pensar ações comunicacionais que tragam de novo o humano em nós. Afinal, será que a sociedade líquida de Bauman teria mesmo anunciado a “A morte das principais utopias sociais”? Progresso e sociedade, homem e máquina são antagonistas que Adorno explicou precisarem um do outro. Nesse cenário, qual o papel da comunicação sindical para informar, conscientizar, reorganizar e levar o trabalhador brasileiro, em suas diferentes áreas de atuação, recuperar os direitos perdidos e avançar numa sociedade livre das mazelas impostas pela economia neoliberal? Sem respostas fáceis, este estudo reflete angústias e pretende, através da análise bibliográfica, a busca das lições aprendidas no passado, quem sabe nortear novos caminhos a serem seguidos. Busca compreender como a imprensa sindical pode ao mesmo tempo em que informa os trabalhadores somar na formação de leitores e como isso contribui para a minimização das perdas e precarização do trabalho no Brasil. Belchior morreu cantando ainda ser moço para tanta tristeza... Seguiremos?
Refugiado: aspecto legal e social

Published: February 2021

O presente trabalho tem como objetivo identificar a relação dos refugiados com a Lei brasileira e o enfrentamento na sociedade diante de um cenário adverso. Buscou-se por meio de uma pesquisa exploratória, entender como o refugiado tem os serviços básicos acolhidos e como é a relação com a sociedade. Contudo, explorar o conceito de direitos humanos e sua trajetória são fatores essenciais para o entendimento da garantia e proteção do refugiado, assim como, delimitar quem são os refugiados e como a lei local aborda a sua proteção. A marginalização das minorias abre caminhos à discriminação, e com a pessoa na figura do refugiado não seria diferente, e tratar desta polêmica, desmistifica todo o estigma que paira sob a pessoa perseguida que vem em busca de melhores condições de vida. Tratou-se, todavia, por análises bibliográficas, esclarecer esta discriminação e o distanciamento do refugiado perante a sociedade, sendo o desconhecimento do que seja refugiado a sua condição para esta vulnerabilidade social. Por fim, a pesquisa nos trouxe um panorama otimista em relação ao acolhimento dos serviços básicos, mas em um comparativo com pontos negativos no que importa a integração do refugiado na sociedade, com lacunas para melhorias, como o entendimento de quem são os refugiados, melhor aceitação dos documentos expedidos pelas autoridades brasileiras, entre outros assuntos identificados ao longo do trabalho.

O presente estudo tem o objetivo de propor e validar uma escala de conceito para a medição da Orientação para o Mercado (OM) no ambiente das Instituições de Ensino Superior privadas de pequeno e médio porte, sob a ótica da discussão de modelos organizacionais. Trata-se de uma pesquisa empírica de natureza descritiva-quantitativa, iniciada pela revisão da literatura para a identificação dos indicadores utilizados na operacionalização da OM, de onde emergiu a proposta de uma escala de mensuração da OM, que foi validada por meio de um processo que envolveu o uso do coeficiente de validade de conteúdo em uma avaliação de juízes, pré-teste e análise estatística de consistência interna e validade discriminante, a partir de levantamento junto à uma amostra probabilística de 161 diretores de PMIES privadas do Estado de São Paulo. Todos os dados foram submetidos à análise fatorial exploratória, o que proporcionou adequações e por fim, a validação da escala, que se tornou um modelo de mensuração da Orientação para o Mercado, consolidada como um construto unidimensional (α = 0,81), operacionalizada por quatro variáveis, que são apresentadas neste artigo.

Published: February 2021

O consumo consciente se relaciona ao modo de vida que valoriza a responsabilidade com o meio ambiente, ou seja, preocupa-se com os impactos da compra, uso e descarte do produto. Este estudo caracteriza-se como pesquisa descritiva e exploratória que utilizou a técnica projetiva com o objetivo de investigar o comportamento dos consumidores de alta renda da cidade de Catalão-GO, de acordo com a visão do Instituto Akatu (2012) no que se refere ao consumo consciente. Aplicou-se um questionário estruturado que apresentava atitudes e comportamentos relacionados ao consumo. Realizou-se uma análise de distribuição de frequência, com ênfase nos resultados que mais se destacaram em relação ao comportamento da amostra escolhida, ou seja, nas atitudes e comportamentos que os consumidores dizem adotar no seu dia a dia em relação ao consumo consciente. Tais dados apresentaram participação consciente no consumo, evidenciando um equilíbrio entre a satisfação pessoal e a sustentabilidade.

Published: February 2021

Abstract Plastic and metal biliary stents can fail to function properly, such failure being due to a positioning error or to the migration, occlusion, or fracture of the stent. An obstructed biliary stent can act as a nidus, causing complications such as recurrent persistent cholangitis. It can also cause vascular complications (such as bleeding and the formation of pseudoaneurysms), perforate the liver capsule (causing biloma or abscess), or, in rare cases, cause intestinal obstruction or perforation. In this pictorial essay, we demonstrate various interventional radiology techniques for the treatment of biliary stent dysfunction in patients with obstructive biliary disease.
Sintomas de ansiedade e depressão entre estudantes de medicina: estudo de prevalência e fatores associados
Authors: Sacramento Bartira Oliveira , Anjos Tassiana Lima dos , Barbosa Ana Gabriela Lopes , Tavares Camila Fagundes , Dias Juarez Pereira
Published: February 2021

Abstract: Introduction: Common Mental Disorders (CMDs) imply psychological distress, interfering with daily activities, interpersonal relationships and quality of life. It is estimated that CMDs affect 9% to 12% of the world’s population and 12% to 15% of the Brazilian population in all age groups. Among different social groups, university students are more vulnerable to the development of anxiety and depression disorders. Objective: Therefore, this study proposed to estimate the prevalence rates and factors associated with symptoms of anxiety and depression in medical students in a capital city of northeast Brazil. Methods: This is a prevalence study, with a probabilistic sample of 1,339 students who regularly attended the 12 semesters of medical school in January 2018. Data were collected by applying a socioeconomic, behavioral and demographic survey and Beck Anxiety and Depression Inventories. The chi-square test was used to check for differences between anxiety and depression symptoms and socioeconomic and behavioral variables. The prevalence rates (total and by level of severity) and the crude and adjusted prevalence ratio (PR) were used as an association measure. Linear trend analysis was used to verify the existence of an association between anxiety and depression symptoms and semesters of the medical school. The variables that showed a crude PR with p <0.20 were incorporated into the multivariate analysis, using the robust Poisson regression model, to determine the adjusted PR. Results: The prevalence of symptoms of anxiety was 30.8%, whereas depression was 36.0%. The crude and adjusted PR for anxiety symptoms showed a statistically significant association with gender, age and sexual orientation. The crude and adjusted PR for symptoms of depression showed a statistically significant association with gender, ethnicity/skin color and sexual orientation. The correlation analyses between the semesters of the course and the presence of anxiety and depression symptoms indicated a weak coefficient of determination, with a descending characteristic and without statistical significance. Conclusions: As this is a prevalence study, this investigation does not allow conclusions on causality. Additional follow-up studies are needed to elucidate the course of anxiety and depression throughout the school semesters.

Authors: Rodway Simon
Published: February 2021

This paper undertakes a comprehensive survey of the syntax of absolute forms of verbs in the corpus of early Welsh poetry known ashengerdd. Comparisons are made with the syntax of absolute forms in Old Irish, in Old Welsh and Old Breton, in Middle Welsh court poetry of the twelfth
century onwards, and with those found in Middle Welsh prose texts.
Left Branch Extraction and Clitic Placement in Gaulish
Authors: Mees Bernard
Published: February 2021

The inscriptional remains of Gaulish preserve syntactic behaviours that are not expected from the perspective of the diachronic schemes usually posited for the development of early Insular Celtic syntax from Proto-Indo-European. Widespread evidence is attested, particularly for the
behaviour of clitics, that does not seem reconcilable with many of the assumptions made in previous studies regarding the nature of the syntax of Proto-Celtic. Gaulish also evidently features scrambling-type phenomena such as left branch extraction that are not usually thought to appear in
other Celtic languages. An analysis which begins with an assessment of these features leads to a more empirically predicated and consistent understanding of the early development of Celtic word order than has been proffered previously.
Geometric morphometrics nesomyinae rodent skulls v1

Published: February 2021

Here we aim to define how skull morphology in an endemic and monophyletic clade of rodents (subfamily Nesomyinae), which show considerable morphological variation and are largely forest-dwelling, has evolved and to characterize this disparity in a geographical and ecological context. We performed a two-dimensional geometric morphometric analysis on 419 dorsal and 444 ventral skull images comprising all nine extant endemic genera (26 different species) and tested the influence of ecological parameters in a phylogenetic context on size and morphology.
