Abstract:
This work describes the physicochemical characterization of the genome and telomere structure from the nematode Oscheius tipulae CEW1. Oscheius tipulae is a free-living nematode belonging to the family Rhabditidae and has been used as a model system for comparative genetic studies. A new protocol that combines fluorescent detection of double-stranded DNA and S1 nuclease was used to determine the genome size of O. tipulae as 100.8 Mb (approximately 0.1 pg DNA/haploid nucleus). The genome of this nematode is made up of 83.4% unique copy sequences, 9.4% intermediate repetitive sequences, and 7.2% highly repetitive sequences, suggesting that its structure is similar to those of other nematodes of the genus Caenorhabditis. We also showed that O. tipulae has the same telomere repeats already found in Caenorhabditis elegans at the ends and in internal regions of the chromosomes. Using a cassette-ligation-mediated PCR protocol we were able to obtain 5 different putative subtelomeric sequences of O. tipulae, which show no similarity to C. elegans or C. briggsae subtelomeric regions. DAPI staining of hermaphrodite gonad cells show that, as detected in C. elegans and other rhabditids, O. tipulae have a haploid complement of 6 chromosomes.Key words: Oscheius tipulae, Caenorhabditis elegans, DNA reassociation, telomere, genome size, karyotype.

În articolul de faţă am încercat să dezvăluim influenţa exercitată de Alecsandri în procesul de circulaţie a versiunilor mioritice din Basarabia. Odată ce Mioriţa este capodopera, care i-a înveşnicit numele, orientându-l spre gloria de poet naţional, această baladă mai poate fi privită drept sinteză a activităţii sale creatoare, „o comoară de adevărată poezie” şi simţiri artistice alese, deschizându-i noi perspective în cariera sa de creaţie. Circulaţia versiunilor mioritice din contextul basarabian nu diferă esenţial de varianta lui Vasile Alecsandri, care s-a dovedit a fi un model ipotetic, simbolul unei realităţi spirituale ,,simţită în toate tipurile şi subtipurile motivului”, cu o vastă sferă de extindere în mai multe regiuni ale ţării, în funcție de particularităţile lor teritoriale. Tipul Alecsandri se regăseşte în mai multe versiuni mioritice într-un context etnologic specific, acesta fiind influenţat de o notă particulară, dar şi de o serie de trăsături individualizatoare, prin acele dimensiuni estetice menite să dezvăluie puterea creatoare a geniului anonim.

Abstract:
Introduction:Knowledge about local airborne allergens in any geographical area is essential for effective diagnosis and treatment of allergic diseases. Tipuana tipu, tree of the Fabaceae family, native from South America, it is present in the main avenues of metropolitan Lima and in some parks (big gardens) of the city. The objective was to report the Tipuana tipu pollen how a new allergen capable of triggering allergic symptoms. Methods:The pollen counts were made according to standardized technique with a Burkard seven days following the European Aerobiology Society´s Network Group recommendations.1 The trap was installed on the roof of Clinica SANNA el GOLF, San Isidro, which is 20 m high, 12°5'54"S 77°3'6"W in the west-south of the Lima urban area. The sampling period was performed from September 2020 to October 2021. Collection of Tipuana tipu pollens and Preparation of Tipuana tipu pollen extracts 1:20 w/v was done using a previously described method.2We carried out systematic skin prick testing with Tipuana tipu pollen extract and other aeroallergens (Dermatophagoides pteronyssinus, Dermatophagoides farinae, Blomia tropicalis), molds (Cladosporium herbarum, Alternaria alternata, Aspergillus fumigatus, Penicillium notatum), cat and dog danders, Periplaneta americana, grass 6 mix, weed mix (Inmunotek, Spain) on 80 patients (18 to 50 years) seen in our allergy center, they suffering from November to January rhinitis and/or conjunctivitis symptoms. The majority living near avenues and large green areas, where Tipuana trees grew. Results:We found a total of 952 grains/m3 of Tipuana tipu pollen between November 2020 to January 2021, with the maximum concentration of 37 grains/m3 on December 10th. We also found other airborne pollen Types: Poaceae, Myrtaceae, Compositae and Betulaceae.14/80 patients (17.5%) showed positive skin prick test only to Tipuana tipu extract. Most of the patients with positive tests to Tipuana extract presented symptoms of rhinoconjunctivitis during the Tipuana pollination period. Four patients showed positive skin prick test to Tipuana tipu and grass 6 mix extracts, most of the rest of our patients were sensitized to dust mites extracts (Dermatophagoides pteronyssinus).Conclusions:The west-south population of Lima urban city is exposed to Tipuana tipu pollen. We do not found previous publications about Tipuana tipu allergy. Almost 18% of the patients tested in our sample were mono-sensitized to this pollen. The results of this study should be compared with data from the forthcoming years, to identify seasonal and annual fluctuations, extend the traps to other locations in Lima, and of course try to standardize and improve the Tipuana tipu pollen extract.

Abstract:
Caenorhabditis elegans est un organisme modèle couramment utilisé pour étudier les processus de développement tels que la formation de la vulve. Ce processus repose sur l'induction précise des cellules qui donnent naissance à la vulve. Les destins cellulaires résultants sont organisés en un motif caractéristique, qui est conservé tout au long du Caenorhabditis et des nématodes rhabditides. En contraste avec cette conservation des cellules vulvaires, ma thèse présente deux axes d'étude qui ont révélé des signatures d'évolution des voies de développement contrôlant l'induction vulvaire. Dans le premier, je présente un changement des motifs cis-régulateurs nécessaires à l'expression cellulaire spécifique de lin-3 (EGF), un gène codant pour la molécule de signalisation qui induit le destin des cellules de la vulve. Les trois sites de liaison aux facteurs de transcription requis pour l'expression de lin-3 chez C. elegans ne sont observés que chez les espèces du groupe Elegans. En utilisant des techniques de FISH à molécule unique et d'édition de génome, je montre que le remplacement des sites endogènes de C. elegans par un fragment de 58 pb contenant un seul site (provenant de C. angaria) produit des niveaux d'ARNm de type sauvage de type lin-3. Je conclus que l'évolution compensatoire pour l'exigence de sites de liaison de C. elegans s'est produite en cis. Dans la deuxième partie de mon étude, j'ai utilisé une approche de cartographie par séquençage et une collection de mutants de la vulve chez Oscheius tipulae, voisin de C. elegans dans le clade rhabditid, afin d'identifier les mutations dans les gènes agissant sur la spécification du modèle de destin des cellules de la vulve. La seule mutation collectée pour rendre les animaux sans vulve correspond à une délétion de la région cis-régulatrice contrôlant l'expression de O. tipulae lin-3, ce que j'ai confirmé par l'édition du génome de CRISPR / Cas9. Les mutants présentant un excès d'induction de la vulve portent des lésions moléculaires dans la voie plexin / semaphorin, un système de signalisation cellulaire qui, selon moi, agit dans le positionnement antéropostérieur des cellules donnant lieu à la vulve par analyse microscopique. Enfin, d’autres animaux d’O. tipulae dont le destin de cellules vulvaires est perturbé présentent des mutations dans des composants de la voie Wnt; pour cette raison, j'ai étudié les profils d'expression des ligands Wnt d'O. tipulae et révélé leur conservation avec C. elegans. Ces deux études mettent en évidence le processus de dérèglement du système de développement (DSD) en tant que processus évolutif qui se produit lors de la formation de la vulve sur des nématodes rhabditides
Caenorhabditis elegans is a model organism commonly used to study developmental processes such as vulva formation. This process relies on the precise fate induction of the cells that give rise to the vulva. The resultant cellular fates are arranged into a characteristic pattern, which is conserved across the vulva development of Caenorhabditis and rhabditid nematodes. In contrast to this extensive conservation of the vulval cell fate pattern, my thesis presents two lines of study that revealed signatures of evolution in developmental pathways controlling vulval induction. In the first one, I present a turnover of cis-regulatory motifs required for the cell-specific expression of lin- 3 (EGF), a gene coding for the signalling molecule which induces vulva cell fates. The three transcription factor binding sites required for lin-3 expression in C. elegans are observed only in species of the Elegans group. Using single-molecule FISH and genome editing techniques, I show that the replacement of the endogenous C. elegans binding sites by a 58 bp fragment containing a single site (coming from C. angaria), produces wild-type mRNA levels of lin-3. I conclude that compensatory evolution for the requirement of C. elegans binding sites occurred in cis. In the second line of study, I used a mapping-bysequencing approach and a collection of vulva mutants in Oscheius tipulae, a neighbour of C. elegans in the rhabditid clade, to identify mutations in genes acting on vulva cell fate pattern specification. The only collected mutation to render animals vulvaless corresponds to a deletion of the cis-regulatory region controlling the expression of O. tipulae lin-3, which I confirmed by CRISPR/Cas9 genome editing. Mutants with an excess of vulva induction carry molecular lesions in the plexin/semaphorin pathway, a cell signalling system which I show to act in the antero-posterior positioning of the cells giving rise to the vulva by microscopic analysis. Finally, other O. tipulae animals with disrupted vulval cell fate pattern hold mutations in components of the Wnt pathway; for this reason, I investigated the expression profiles of Wnt ligands of O. tipulae and revealed their conservation with C. elegans. Both of these studies highlight the process of Developmental System Drift (DSD) as an evolutionary process occurring on vulva formation of rhabditid nematodes

Abstract:
Os estudos sobre o clima vêm adquirindo grande importância na área ambiental, principalmente em relação à qualidade do ar (poluição atmosférica), ao conforto térmico (ilhas de calor) e aos impactos pluviais (geradores de inundações urbanas). Nesses últimos, as chuvas causam muitos transtornos para a população e órgãos públicos competentes, devido aos eventos extremos, que estão acontecendo em toda parte do mundo. Esses eventos ocorrem desde uma chuva com muita intensidade, em curto espaço de tempo, até seca prolongada em certos lugares. O fato é preocupante e mesmo com tantas controvérsias sobre o assunto, é necessário um manejo, principalmente no sistema hidrológico, que se adeqüe a cada situação e que os prejuízos causados pelas enchentes não se tornem mais devastadores do que atualmente. Como a arborização pode amenizar tais efeitos impactantes, nesse propósito, foi realizado um estudo no campus da ESALQ/USP, durante o período de janeiro a fevereiro de 2007, para medir a interceptação da água da chuva pelas copas das árvores e verificar como algumas espécies poderiam minimizar enchentes em áreas urbanas. O processo de interceptação da água da chuva foi analisado em duas espécies muito comumente usadas na arborização urbana, visando obter estimativas da quantidade de interceptação (I) ou perda por interceptação, precipitação interna (PI), escoamento pelo tronco (Et) e precipitação total (PT). As espécies escolhidas foram Caesalpinia pluviosa DC. (Fabaceae: Caesalpinoideae), ou sibipiruna, e Tipuana tipu O. Kuntze (Fabaceae: Faboideae), ou tipuana, com mais de 50 anos de idade, sendo três indivíduos isolados e três em grupo de cada espécie. As medições foram feitas por meio de coleta da água não interceptada tanto nas extremidades como no centro da projeção das copas. A PI apresentou alta correlação com a quantidade de PT no centro da copa em tipuana, e na extremidade da copa em sibipiruna. O Et e a I tiveram baixa correlação com a quantidade de PT nas duas espécies. As médias de interceptação foram maiores na extremidade da copa nos indivíduos de sibipiruna, com 60,6%, e no centro da tipuana, com 59,4%. Para precipitações variando de 0 a 2,5 mm, a interceptação média foi de 78,7%, em um indivíduo de sibipiruna, na extremidade da copa e, de 80,9% nos indivíduos de tipuana, em grupo, no centro da copa. Enquanto que, para precipitação de 2,5 a 5,0 mm, a interceptação foi de 53,6% para tipuana em grupo, na extremidade e, de 51,9% na tipuana isolada, no centro da copa. A tipuana apresentou maior porcentagem média de interceptação no centro da copa, principalmente em eventos com mais de 2 horas de duração e com precipitação maior que 20,0 mm, tanto em indivíduos isolados como em grupo. Portanto, as duas espécies demonstraram grande potencial para serem plantadas no ambiente urbano, com capacidade de contribuírem para possíveis reduções das enchentes nas cidades, principalmente a tipuana que mostrou mais predisposta a essa ação.
Climate studies are receiving more attention in the environmental field, especially concerning air quality (atmosphere pollution), thermal comfort (heat islands) and pluvial impacts (urban flood generators). In the latter, the rain causes disturbance of the population and the competent public organ, due the extreme events that are increasing in the whole world. Theses events can come as a precipitation of very intensity in a short period of time, as well as a prolonged drought in a given location. The issue is worrisome and controversial, however a managerial solution is necessary and urgent, particularly about the hydrologic system for each situation so that the losses caused by floods do not become more devastating than now. With these purpose in mind, a study was carried out at the campus of \"Luiz de Queiroz\" College of Agriculture (University of Sao Paulo), Piracicaba, Brazil, from January to February 2007, in order to measure the rainfall interception by the crows of urban trees and estimate the rainfall interception that they provide to potentially minimize urban flood events. The rainfall interception was evaluated in the two commonly used species in forest urban spaces by the measurement of interception (I) or interception losses, throughfall (Th), stemflow (St) and gross precipitation (Pg). The chosen trees were more than 50 year-old specimens of Caesalpinia pluviosa DC. (Fabaceae: Caesalpinoideae) or sibipiruna, and Tipuana tipu O. Kuntze (Fabaceae: Faboideae) or tipuana, both displayed as three isolated individuals and three grouped individuals. Measurements were carried out by collecting the water falling by the edges and in the centre of the canopies. A high correlation of Th with Pg was observed on the centre of the crow of tipuana and by the edges of sibipiruna. St and I had low correlation with Pg for both species. . The rain interception mean was higher by the edges of the crow of sibipiruna individuals, 60.6%, and in the centre of the tipuana crow, 59.40%.The mean of the rainfall interception was 78.73% for one isolated sibipiruna by the edge of the crow and 80.94% for grouped tipuanas in centre of the crow, when the total precipitation ranged between 0 and 2.5 mm. For total precipitation values between 2.5 and 5.0 mm, the interception mean was 53.60% for grouped tipuanas by the edge and 51.89% in isolated tipuanas in the crow center. Thus, both species show a great potential to be planted in urban environmental, especially for the tipuana species, which presented the capacity of contributing better to reduce or minimize floods in cities.

Abstract:
A região N-terminal de OTI-VIT-1 foi expressa e os polipeptídeos recombinantes foram purificados. OTI-VIT-1 pode ser homólogo da vitelina YP170B de C. elegans. Foram identificados um intron na região 5´ e dois na região 3´ do gene Oti-vit-1. Antissoro monoespecífico para PVIT1HisC confirmou que o gene Oti-vit-1 codifica VT1. O polipeptídeo recombinante P40-H, correspondente à região N-terminal da proteína OTI-VIT-6 interage com um polipeptídeo de aproximadamente 100 kDa (P100) presente em extratos proteicos totais de O. tipulae. Estudamos também o papel da Proteína Microssômica Transportadora de Triglicerídeos (MTP) na biossíntese de Vitelogenina do nematoide C. elegans. Ensaios de RNAi em C. elegans, utilizando parte da sequência do gene da MTP (Cel-dsc-4) foram realizados nas linhagens N2 e DH1033. Microscopia de fluorescência de vermes adultos da linhagem DH1033, submetidos a RNAi, mostrou acúmulo de YP170B::GFP no interior dos enterócitos. Este acúmulo sugere a participação da MTP na secreção de VTG. Análise imunológica da vitelogenina nestes mesmos vermes não detectaram alterações no processamento de CEL-VIT-6, sugerindo que o mesmo ocorra não só no pseudoceloma, mas também no interior dos enterócitos.
The N-terminal region of OTI-VIT-1 was expressed and the recombinant polypeptides were purified. OTI-VIT-1 may be homologous to the vitellin YP170B from C. elegans. We identified an intron in the 5 \'region and two in 3\' region from Oti-vit-1. Monospecific antisera to PVIT1HisC confirmed that the gene Oti-vit-1 encodes VT1. The recombinant polypeptide P40-H, corresponding to the N-terminal region of the protein OTI-VIT-6, interacts with a polypeptide of approximately 100 kDa (P100) present in total protein extracts of O. tipulae. The role of microsomal triglyceride transfer protein (MTP) in the biosynthesis of vitellogenin was studied in the nematode C. elegans. Trials of RNAi in C. elegans, using the sequence of the MTP gene (Cel-dsc-4) were performed in the strains N2 and DH1033. Fluorescence microscopy of adult worms of strain DH1033, subjected to RNAi, showed accumulation of YP170B:: GFP within the enterocytes. This accumulation suggests the involvement of MTP in the secretion of VTG. Analysis using anti-vitellogenin immune serum did not detect changes in the processing of CEL-VIT-6, suggesting that it occurs not only in pseudocoelom but also within the enterocytes.

Abstract:
As árvores desempenham papel fundamental na qualidade ambiental das áreas urbanas. Como a floresta urbana é alvo constante de ações inadequadas de manejo, tais como podas inapropriadas, técnicas que visam avaliar a qualidade dos indivíduos e o risco de queda de árvores são fundamentais para a diminuição de possíveis danos causados aos equipamentos urbanos além de risco aos habitantes das cidades. Os métodos de avaliação visual de árvores desenvolvidos para a identificação de problemas biomecânicos e fitossanitários possibilitaram que avaliações de risco de queda fossem conduzidas. Nesses métodos, inspeções detalhadas a respeito da extensão das lesões presentes no colo e tronco, que podem comprometer sua estabilidade, são recomendadas para os indivíduos. Entre as técnicas utilizadas para o reconhecimento de lesões internas, a tomografia destaca-se por fornecer informações a respeito de toda seção avaliada com apenas uma medição e por gerar uma imagem que permite identificar o posicionamento e a extensão das áreas lesionadas. Por ser um método relativamente novo, são necessários estudos que visem identificar a resposta à tomografia em diferentes espécies, possibilitando desta forma a identificação precisa das áreas lesionadas. O trabalho realizado teve por objetivo testar a confiabilidade das informações geradas pela tomografia de impulso e identificar padrões de resposta em árvores de tipuana (Tipuana tipu (Benth.) O. Kuntze). Trinta e nove indivíduos que apresentaram sinais de injúria, apodrecimento, inclinação ou outros fatores que pudessem prejudicar sua estabilidade ou desenvolvimento foram avaliados por essa técnica. As velocidades de propagação de onda mecânica obtidas pela tomografia de impulso foram comparadas às leituras de resistência à penetração medidas por resistógrafo, objetivando identificar a correlação existente entre a tomografia de impulso e um método amplamente difundido para a quantificação de lesões internas (resistógrafo). As imagens que mostraram sinais nítidos de lesão foram avaliadas estatisticamente, o que possibilitou o reconhecimento de que velocidades de propagação de ondas mecânicas iguais ou inferiores a 729,65 m.s-1 representam tecidos lesionados para a espécie. As áreas periféricas às lesões avaliadas não apresentaram diferenças estatisticamente significativas em relação às velocidades encontradas. Análises estatísticas indicam a existência de forte correlação entre as leituras tomográficas e do resistógrafo. Foi obtido coeficiente de determinação (R²) igual a 0,9977 no modelo adotado. A tomografia de impulso é uma importante ferramenta para a complementação da avaliação visual de árvores, permitindo a identificação e quantificação precisa de lesões internas na seção avaliada.
Trees perform a fundamental role in environmental quality of urban environments. As the urban forest is often exposed to inadequate management actions, such as improperly pruning, techniques to evaluate the quality of individuals and the risk of trees falling are essential to reduce the possible hazard to urban equipment and the risk to city dwellers. The visual tree assessment developed for the identification of biomechanical problems made it possible for hazard assessments to be conducted. In these methods, detailed inspections regarding the extent of the lesions found in the root collar and trunk are recommended for those who had clear signs of injuries that can affect their stability. Among the techniques used for the recognition of internal injuries, tree tomography is noted for providing information regarding an entire cross-section evaluated with only one measurement, generating an image that identifies the position and extent of injured areas. Being a relatively new method, studies aimed to identifying the tomography response in different species are needed, thus to enable an accurate identification of the injured areas. This work aimed to test the reliability of the information generated by the impulse tomography and to identify patterns of response on tipuana trees (Tipuana tipu (Benth.) O. Kuntze). Thirty-nine individuals of tipuana that presented signs of injury, decay, leaning or other factors that could affect its stability or development were evaluated by this technique. The speed of mechanical wave propagation obtained by the impulse tomography was crossed to resistograph measurements readings of resistance to penetration in order to identify the correlation between impulse tomography and a method widely known for the quantification of internal injuries (resistograph). The imagery showing clear signs of injury was evaluated statistically, allowing to identify that mechanical waves propagation with speed equal or lower than 729,65 m.s-1 represents injured tissues for the specie. The peripheral lesion areas evaluated did not show statistically significant differences in the speeds found. Statistical analysis indicates that there was a strong correlation between the readings of impulse tomography and resistograph. The coefficient of determination (R²) equal to 0.9977 was obtained in the adopted model.

Abstract:
Os objetivos do presente trabalho foram: avaliar o processo de biodeterioração do lenho das árvores de tipuana na cidade de São Paulo e relacionar as alterações da sua estrutura anatômica e propriedades físico-mecânicas com o seu risco de queda. Nos passeios públicos de regiões selecionadas da cidade, 1109 árvores de tipuana foram caracterizadas quanto às condições de entorno, estado geral, variáveis dendrométricas, biodeterioração externa e interna e o risco de queda, estimado com modelo de cálculo estrutural desenvolvido pelo IPT. A biodeterioração e os mecanismos de resistência das árvores foram avaliados ao nível macroscópico e microscópico. As alterações nas propriedades do lenho de tipuana foram analisadas por densitometria de raios X e pelos ensaios físico-mecânicos (densidade de massa aparente; resistência à flexão) e aplicado o método de elementos finitos para análise da distribuição de tensões no lenho. As árvores de tipuana de elevada idade não apresentaram sinais de declínio, embora com estado geral considerado como crítico, pelo plantio em locais indequados, manejo inapropriado e/ou ocorrência de injúrias. O lenho foi deteriorado por fungos apodrecedores, cupins-subterrâneos e brocas-de-madeira, sendo os fungos e cupins os principais organismos xilófagos, afetando a região do cerne; a associção entre os fungos, os cupins, as variáveis dendrométricas e o risco de queda foram estatisticamente significantes ao nível de 5 %. O cupim-subterrâneo Coptotermes gestroi ocorreu em elevados níveis de infestação nas árvores, sendo considerado, no entanto, como um organismo-praga secundário, fortemente associado com lenho previamente apodrecido por Ganoderma sp.. Os fungos apodrecedores ocorrentes foram classificados como de podridão branca e mole, sendo a primeira mais comum no cerne das árvores. Como mecanismo de resistência à biodeterioração observou-se a compartimentalização do lenho, caracterizada pelo acúmulo de extrativos nas células. Os fungos xilófagos causaram reduções significativas na densidade de massa aparente, tensão de ruptura à flexão estática e módulo de elasticidade em estágios incipiente e intenso de apodrecimento do lenho. Ruptura do tronco e o risco de queda das árvores de tipuana relacionaram-se, principalmente, com a intensidade da deterioração do lenho e com a sua dendrometria. A alteração da distribuição das tensões no lenho foi analisada em relação ao estágio, tamanho e localização da deterioração no tronco das árvores de tipuana.
The objectives of the present work were to evaluate the process of biodeterioration in the wood of tipuana trees in the city of São Paulo and to relate the alterations in the anatomical structures and physical and mechanical properties with there falling risk. In the sidewalks of selected regions of the city, 1109 trees were characterized taking into consideration aspects as surroundings, general conditions, dendrometric variables, external and internal biodeterioration and falling risk estimated by using a structural model developed by IPT. The biodeterioration and the resistance mechanisms of the trees were evaluated at a macro and microscopic levels. The alterations on the wood properties were analysed by X-rays densitometry and by performing physical and mechanical tests (specific gravity; bending resistance); the tension distribution in the wood was analyze by finite-elements method. The old aged trees encountered, did not show any sign of decline, eventhough, the general aspect of their surroundings was critical by the inadequate places they were planted; inappropriate management and/or occurrence of injuries. The trees had their trunks deteriorated by xylophagous organisms, mainly fungi and subterranean-termites, and some wood borer beetle too, which affected the heartwood. The association between the presence of the first two organinsms, the dendrometric variables and the risk of falling, was statistically significant at the 5% level. The infestation of the trees by the subterranean-termite Coptotermes gestroi was at high levels, however, it was considered as a secundary plague-organism, because its attack was strongly associated with the previously decayed heartwood by Ganoderma sp.. The decaying fungi observed were classified as white rot and soft rot, being the white rot more common in the heartwood of the trees. As a resistance mechanism of the trees against biodeterioration, it was observed the compartimentalization of the wood characterized by the accumulation of extractives in the cells. Decaying fungi caused significant reductions in the following wood properties: specific gravity, rupture strength to bending and modulus of elasticity either in incipient or intense decay. Trees trunk rupture and falling risk were associated mainly to biodeterioration intensity and dendrometric variables. The alteration of tension distribution in the wood was analyzed in relation to the stage, size and position of the deterioration in the wood of the trees.

Abstract:
This study investigated the ecology of a boreo-alpine crane-fly, Tipula montana Curtis (Diptera: Tipulidae), on a Scottish mountain summit. It explored adaptation to the upland environment, placing emphasis on sources of variation in growth, abundance, and low temperature tolerance. The development stages of larvae were reliably identified from measurements of the spiracular disc diameter. The sex of larvae were distinguished by the bimodal frequency distribution of weights in the 4th instar. Larvae were sampled by hand searching and collecting off snow patches, between 1994 and 1996. The timing and size of development stages indicated that the population possessed a 2-year life cycle, supported by evidence from adult emergence. However, by rearing larvae of known developmental stage at the field site, it was shown experimentally that microhabitat could affect growth, and that it was likely to be related to temperature. In the laboratory, pre-pupal development was shown to be temperature dependent. 2nd instar larvae were reared on single bryophyte diets, from a range of genera. They were all capable of growth and moulting, although final weights differed by a factor of 2. A pair-wise preference experiment, using 4th instars, showed the individuals broadly chose bryophyte foods as expected from their quality, although the sedge Carex bigelowii was preferred over all mosses. No intersexual difference was detected. The observational method of assessing preference, compared to faecal pellet analysis, showed a bias towards some species, perhaps because they acted as a refuge. The pellet contents of a small number of larvae from the field were largely unidentifiable. Larval cold tolerance was investigated in the laboratory. The supercooling points of 3 different species (T. montana, T. varipennis & T. confusa), from upland and montane habitats, were very similar in autumn and spring, ranging from means of -4.5 to -6.0oC.

Abstract:
Harvey, Cohen, and Danforth examine health among the Tipu Maya of Colonial Belize in “Living on the Edge” through the prism of Naum’s (2011) concept of frontiers created under colonialism. The authors embrace a multi-method approach where diverse lines of independent but complementary data are assembled to characterize the health of the 588 Tipu Maya during the sixteenth and seventeenth centuries. Harvey and colleagues’ analysis integrates data from ethnohistory, mortuary patterns, paleodemography, multiple expressions of subadult health (i.e., macro- and micro enamel defects, anemia, Harris Lines), adult health (i.e., specific and non-specific skeletal infection), traumatic injury, and cortical bone maintenance. Hypothesizing that the Tipu population living in the tumultuous Yucatán would demonstrate particularly high rates of skeletal pathological conditions (particularly violent trauma). Harvey and colleagues observed quite the opposite. They argue that the frontier nature of Tipu was itself a contested hybrid space—a kind of borderland, or “Third Space.” Living in this liminal zone between the different political spheres likely allowed for Tipuans to create a distinct identity and social experience that compared to other Colonial Maya communities, shielded them from greater degrees of biological stress and morbidity.

Abstract:
Sausra – vienas iš daugiausiai nuostolių sukeliančių gamtinių reiškinių tiek Europoje, tiek visame pasaulyje. Dėl besikeičiančio klimato tikslesnis sausrų identifikavimas, jų išplitimo vertinimas pastaruoju metu tampa vis aktualesne tema ir Lietuvoje. Pastaraisiais dešimtmečiais sausroms stebėti ir identifikuoti sukurta daugybė indeksų. Vienas iš jų – temperatūros ir augmenijos sausumo indeksas TVDI (angl. Temperature Vegetation Dryness Index), apskaičiuojamas naudojant palydovinius duomenis. Pagrindinis šio darbo tikslas – įvertinti TVDI pritaikomumą stichinių sausrų išplitimo ir intensyvumo vertinimui skirtinguose žemėnaudos tipuose Lietuvoje 2002–2019 metais. Siekiant išskirti sausras, apskaičiuotas TPI rodiklis (angl. Temperature–Precipitation Index) – oficialus sausrų identi- fikavimo kriterijus Lietuvoje. Nustatytų sausrų metu visai Lietuvos teritorijai buvo apskaičiuotos TVDI vertės. Šiam tikslui pasiekti panaudoti NASA Aqua palydove įmontuoto MODIS jutiklio teikiami 8 dienų kompozicijos duomenys apie paviršiaus temperatūrą (LST) bei 16 dienų kompozicijos duomenys apie augmenijos žalumą (NDVI). Sausros at- skirai vertintos šešiuose skirtinguose žemėnaudos tipuose, išskirtuose naudojant CORINE Land Cover (CLC) 2018 metų duomenis apie Žemės paviršiaus biofizines charakteristikas. Remiantis TPI vertėmis 2002–2019 metais Lietuvoje išskirtos keturios sausros: 2002 metų liepos–rugsėjo mėnesiais, 2006 metų birželio–liepos mėnesiais, 2008 metų gegužę ir 2019 metų balandžio–gegužės mėnesiais. Nustatyta, kad didžiausią teritorijos dalį apėmė 2002 metų sausra. Ji labiausiai išplito derlingose centrinėje ir pietvakarinėje Lietuvos dalyse bei Pajūrio regione. Vertinant sausrų išplitimą skirtinguose žemėnaudos tipuose nustatyta, kad visais keturiais atvejais sausra labiausiai išplito dirbamoje žemėje arba ganyklose, o mažiausiai – spygliuočių miškuose.

Abstract:
Facility management (FM) ca o industrie a apărut ca unul dintre sectorul cu cea mai rapidă creștere de-a lungul deceniului. Cu toate acestea, domeniul de aplicare și identitatea FM este încă neclară, după cum reiese din definițiile și problemele care încearcă să descrie domeniul său de aplicare. De fapt, FM este tipul multidisciplinar de muncă care acoperă o gamă largă de activități, responsabilități și cunoștințe diferite. Mai mult decât atât, fiecare aspect al unei organizații pare să fie atras în FM. FM oferă și gestionează o varietate de servicii de asistență pentru a orchestra toate funcțiile organizației, punând accentul pe o integrare a activităților primare atât la nivel strategic, cât și operațional. Se așteaptă ca managerii de facilități să fie informați și să posede o gamă largă de abilități administrative și de conducere. În plus, FM ar trebui să integreze cunoștințe atât despre facilități, cât și despre management, pentru a funcționa eficient.
