Proiektu honetan, futbolean jokatzen duten eta Aurreko Lotailu Gurutzatuko haustura jasan duten pertsonentzako erreadaptazio edo ber egokitzapen proposamen bat egin da. Honela, lanaren lehenengo zatia funtsean teorikoa da, baina oso garrantzitsua izango da ondorengo puntu hauek hobetu ulertu ahal izateko eta gaiaren gaur egungo egoeraz jabetzeko: futboleko lesioen duela urte gutxiko edo gaur egungo egoera, lesio horien maiztasun eta kokapena, bai eta lesio horien ezaugarriak. Ondoren, Aurreko Lotailu Gurutzatuan zentratu naiz, lotailu horren ezaugarriak, funtzioak, etab. aipatuz eta gero lotailu horren apurketan arreta jarri dut. Gero apurketa horrendako, diagnostikoa, tratamendua eta errehabilitazioa zein den aztertu eta izendatu dut, egile ezberdinen lanak eta ikerketak kontuan harturik. Azkenik, ber egokitzapen edo erreadaptazio proposamen bat egiten dut, modu praktiko batean, landu beharreko giharren eta eragina duten ahalmen fisiko ezberdinak kontuan hartuz, bai metodo eta ariketa egokiak aukeratzen

[EUS] Aurreko Ligamendu Gurutzatuen (ALG) lesioa gaur egun kirolean gehien ematen den lesioetako bat da. Lesio hau askoz ere ohikoagoa da emakumeengan, eta batez ere kontakturik gabeko egoeretan ematen da. Lesio honen tratamendu eta errekuperazio metodo desberdinak daude gaur egun. Lan honetan bi kasu desberdinen konparaketa egingo da, batez ere, operazio ondorengo errekuperazioan ematen diren desberdintasunetan, eta hauen emaitzetan zentratuz ondorioak atera ahal izateko.

[EU]Lan honek bizikletako aurreko gurpileko abatz baten CAM edo CNC programazioa egitean datza, honen bidez erremintaren ibilbidea deskribatuz piezaren CAD eredutik abiatuz. Hasteko, zenbakizko kontrolak izan duen eboluzioa eta garrantzia azaltzen da. Ondoren, abatzaren funtzionamenduaren deskribapena egin da, bere osagaiak eta izan behar dituen ezaugarriak aztertuz. Gainera, fabrikazio prozesu ezberdinen analisia egin da, bakoitzaren abantaila eta desabantailak azpimarratuz. Azkenik, zenbakizko kontrolaren inguruan bereganatutako ezagutzak aplikatu dira CAM programa batean abatz baten mekanizazioa programatuz. Honez gain, erabilitako CAM programaren erabilera azaltzen da.

In this study I offer a diachronic solution for a number of difficult inflectional endings in Old Church Slavic nominal declensions. In this context I address the perhaps most disputed and the most important question of the Slavic nominal inflectional morphology: whether there was in Proto-Slavic an Auslautgesetz (ALG), a law of final syllables, that narrowed the Proto-Indo-European vowel */o/ to */u/ in closed word-final syllables. In addition, the work contains an exhaustive morphological classification of the nouns and adjectives that occur in canonical Old Church Slavic. I argue that Proto-Indo-European */o/ became Proto-Slavic */u/ before word-final */s/ and */N/. This conclusion is based on the impossibility of finding credible analogical (as opposed to phonological) explanations for the forms supporting the ALG hypothesis, and on the survival of the neuter gender in Slavic. It is not likely that the */o/-stem nominative singular ending */-u/ was borrowed from the accusative singular, because the latter would have been the only paradigmatic form with the stem vowel */-u-/. It is equally unlikely that the ending */-u/ was borrowed from the */u/-stems, because the latter constituted a moribund class. The usually stated motivation for such an analogical borrowing, i.e. a need to prevent the merger of */o/-stem masculines with neuters of the same class, is not tenable. Extra-Slavic, as well as intra-Slavic evidence suggests that phonologically-triggered mergers between two semantically opaque genders do not tend to be prevented, but rather that such mergers lead to the loss of the gender opposition in question. On the other hand, if */-os/ had not become */-us/, most nouns and, most importantly, all adjectives and pronouns would have lost the formal distinction between masculines and neuters. This would have necessarily resulted in the loss of the neuter gender. A new explanation is given for the most apparent piece of evidence against the ALG hypothesis, the nominative-accusative singular of the */es/-stem neuters, e.g. nebo 'sky'. I argue that it arose in late Proto-Slavic dialects, replacing regular nebe, under the influence of the */o/- and */yo/-stems where a correlation had emerged between a hard root-final consonant and the termination -o, on the one hand, and a soft root-final consonant and the termination -e, on the other.

Phylogenetic studies of cyanobacterial lichens Lichens are symbiotic assemblages between fungi (mycobiont) and green algae (phycobiont) or/and cyanobacteria (cyanobiont). Fossil records show that lichen-like symbioses occurred already 600 million years ago. Lichen symbiosis has since then become an important life strategy for the Fungi, particularly for species in the phylum Ascomycota as approximately 98% of the lichenized fungal species are ascomycetes. The taxonomy of lichen associations is based on the mycobiont. We reconstructed, using DNA sequence data, hypotheses of phylogenetic relationships of lichen-forming fungi that include species associated with cyanobacteria. These hypotheses of phylogeny should form the basis for the taxonomy. They also allowed studies of the origin and the evolution of specific symbioses. Genetic diversity and phylogenetic relationships of symbiotic cyanobionts were also studied in order to examine selectivity of cyanobionts and mycobionts as well as possible co-evolution between partners involved in lichen associations. The suggested circumscription of the family Stereocaulaceae to include Stereocaulon and Lepraria is supported. The recently described crustose Stereocaulon species seem to be correctly placed in the genus, although Stereocaulon traditionally included only fruticose species. The monospecific crustose genus Muhria is also shown to be best placed in Stereocaulon. Family Lobariaceae as currently delimited is monophyletic. Within Lobariaceae genus Sticta including Dendriscocaulon dendroides form a monophyletic group while the genera Lobaria and Pseudocyphellaria are non-monophyletic. A new classification of Lobariaceae is obviously needed. Further studies are however required before a final proposal for a new classification can be made. Our results show that the cyanobacterial symbiotic state has been gained repeatedly in the Ascomycota while losses of symbiotic cyanobacteria appear to be rare. The symbiosis with green algae is confirmed to have been gained repeatedly in Ascomycota but also repeatedly lost. Cyanobacterial symbioses therefore seem to be more stable than green algal associations. Cyanobacteria are perhaps more beneficial for the lichen fungi and therefore maintained. The results indicate a dynamic association of the lichen symbiosis. This evolutionary instability will perhaps be important for the lichen fungi as the utilization of options will perhaps enable lichens to colonize new substrates and survive environmental changes. Some cyanobacterial lichen genera seem to be highly selective towards the cyanobiont while others form symbioses with a broad spectrum of cyanobacteria. No evidence of co-evolution between fungi and cyanobacteria in cyanolichens could be demonstrated.

In this article we study the one-dimensional random geometric (random interval) graph when the location of the nodes are independent and exponentially distributed. We derive exact results and limit theorems for the connectivity and other properties associated with this random graph. We show that the asymptotic properties of a graph with a truncated exponential distribution can be obtained using the exponential random geometric graph. © 2007 Wiley Periodicals, Inc. Random Struct.
