Our goal is to try to enhance the QoL of persons with hemiplegia by the mean of an active motion support system based on the HAL 's technology. The HAL Hybrid Assistive Limb in its standard version is an exoskeleton-based robot suit to support and enhance the human motor functions.
The purpose of the research presented in this paper is the development of a new version of the HAL to be used as an assistive device providing walking motion support to persons with hemiplegia. It includes the realization of the single leg version of the HAL and the redesign of the original HAL 's Autonomous Controller to execute human-like walking motions in an autonomous way. Clinical trials were conducted in order to assess the effectiveness of the developed system.
The first stage of the trials described in this paper involved the participation of one hemiplegic patient who has difficulties to flex his right knee. As a result, the knee flexion support for walking provided by the HAL appeared to improve the subject's walking longer stride and faster steps.

The first evaluation of the system with one subject showed promising results for the future developments. The efficacy of hybrid assistive limb HAL rehabilitation in the acute phase of stroke remains unclear. The purpose of this study was to evaluate the outcomes of patients with acute intracranial hemorrhage ICH who were treated with or without HAL rehabilitation.
Among patients with acute ICH from to , 91 patients with supratentorial ICH were included in this retrospective study. We obtained various patient data from the hospitals where the patients were moved to for further rehabilitation. The presence of the halogen bonding in 3 was confirmed by theoretical calculations at the density functional theory DFT, MX level, and its nature was analyzed.
Chemical composition of HAL , an isotopically-unusual Allende inclusion. It is concluded that the distribution of REE between hibonite and rims was established when hibonite and other refractory minerals were removed at slightly different temperatures from a hot, oxidizing gas in which they previously coexisted as separate grains.
Possible locations for the chemical and mass dependent isotopic fractionation are considered to be in ejecta from the low temperature helium-burning zone of a supernova and in the locally oxidizing environment generated by evaporation of interstellar grains of near-chondritic chemical composition.
On the basis of their relative crystallochemical analysis fullerides obtained were shown to be isostructural. The main parameters of molecular structure are presented. Compiler organization is discussed, including overall compiler structure, internal data transfer, compiler development, and code optimization. The user, system, and SDL interfaces are described, along with compiler system requirements. The peculiar isotopic, mineralogical and textural properties of HAL are accompanied by very unusual trace element abundances. The most striking feature of the chemistry is the virtual absence of Ce from an inclusion otherwise highly enriched in REE compared to C1 chondrites.
Of the lithophile elements determined which are normally considered to be refractory in a gas of solar composition, Sr, Ba, Ce, U and V are the most volatile in oxidizing gases. The distribution of REE between hibonite and rims seems to have been established when hibonite and other refractory minerals were removed at slightly different temperatures from a hot, oxidizing gas in which they previously coexisted as separate grains.
On the basis of HAL 's chemical and isotopic composition, possible locations for the chemical and mass dependent isotopic fractionation are discussed. A retrospective diagnosis of epilepsy in three historical figures: St Paul, Joan of Arc and Socrates. It has been suggested that undiagnosed epilepsy profoundly influenced the lives of several key figures in history.
Historical sources recounting strange voices and visions may in fact have been describing manifestations of epileptic seizures rather than more supernatural phenomena. Well-documented accounts of such experiences exist for three individuals in particular: Socrates, St Paul and Joan of Arc. The great philosopher Socrates described a 'daimonion' that would visit him throughout his life.
This daimonion may have represented recurrent simple partial seizures, while the peculiar periods of motionlessness for which Socrates was well known may have been the result of co-existing complex partial seizures. St Paul's religious conversion on the Road to Damascus may have followed a temporal lobe seizure which would account for the lights, voices, blindness and even the religious ecstasy he described.
Finally, Joan of Arc gave a detailed narrative on the voices she heard from childhood during her Trial of Condemnation. Her auditory hallucinations appear to follow sudden acoustic stimuli in a way reminiscent of idiopathic partial epilepsy with auditory features. By analysing passages from historical texts, it is possible to argue that Socrates, St Paul and Joan of Arc each had epilepsy.
Oxidation product formation, yellowing and embrittlement as measured in an instrumented bend test have been compared with product formation.
A partial correlation between suppression of oxidation during the irradiation step with long term, post-irradiation oven aging at 60 degrees C was found, but complicated by extensive destruction during irradiation of the active phenolic functionality in some additives, essential for peroxyl radical scavenging. Very long lifetimes with barely detectable yellowing were found for combinations of the amines with completely unhindered or only partially hindered phenols. Hal : an automated pipeline for phylogenetic analyses of genomic data. The rapid increase in genomic and genome-scale data is resulting in unprecedented levels of discrete sequence data available for phylogenetic analyses.
Major analytical impasses exist, however, prior to analyzing these data with existing phylogenetic software. Obstacles include the management of large data sets without standardized naming conventions, identification and filtering of orthologous clusters of proteins or genes, and the assembly of alignments of orthologous sequence data into individual and concatenated super alignments. Here we report the production of an automated pipeline, Hal that produces multiple alignments and trees from genomic data.
These alignments can be produced by a choice of four alignment programs and analyzed by a variety of phylogenetic programs. The results from an example analysis of Kingdom Fungi are briefly discussed. The year of magical thinking: Joan Didion and the dialectic of grief.
COM VIURE JESÚS EN FAMÍLIA (CATALÁN)
Joan Didion is a prominent American writer. In late , while her only child lay critically ill, her husband, John, died suddenly. Theirs was a marriage of great intimacy and love. Grief enveloped her. Eventually she began to write an account of the first 12 months of her bereavement and the vigil for her child: The year of magical thinking. Raw, insightful and challenging, it is a rich, generous and graceful document. Didion draws on the literature of grief, personal and professional. Here, those readings are examined and reflections are made on the singular, unique grief of the author in the context of current theories on bereavement.
Vanishing point: Joan Didion and the horizons of historical knowledge. This dissertation is a biographical study of the life of a retired high school principal in Jamaica. This study of Wint's life centers on school transformation and organizational change, exploring her leadership as a principal through the….

The results are discussed. Influence of the halothane gene HAL on pork quality in two commercial crossbreeds. We evaluated the effect of the halothane HAL gene on the quality of pork in domestic pigs. Half-carcasses from two different commercial pig Sus domestica crossbreeds were analyzed, 46 of which were homozygous dominant HAL NN and 69 of which were heterozygous HAL Nn for the halothane gene.
The measures included backfat thickness, lean meat percentage, carcass weight, pH 24 h after slaughtering, color, and drip loss; DNA was extracted from the haunch muscle. The meat color was paler in HAL Nn animals, the drip loss was greater in those animals bearing the n allele, and the amount of intramuscular fat was not related to the halothane genotype. We conclude that bearers of the recessive allele of the halothane gene produce more meat, but with quality parameters that are inferior to those sought by consumers and industry. Full Text Available In a discovery was made at the Department of Prints and Drawings of the National Museum in Warsaw - a drawing hitherto described as a Kneeling knight by an anonymous seventeenth-century artist, turned out to be Joan of Arc, a sketch well-known to art historians studying the oeuvre of Peter Paul Rubens, although thought to be lost during the Second World War.
The drawing, until now known only through the black and white photograph, could be thoroughly analysed for the first time. In the context of information thus obtained, the historical context of creating the sketch transpired as an equally important matter, including the hypothetical role that may have been played in its creation by Nicolas-Claude Fabri de Peiresc. The histidine ammonia-lyse gene HAL encodes the histidine ammonia-lyase, which catalyzes the first reaction of histidine catabolism.
In our previous genome-wide association study in Chinese Holstein cows to identify genetic variants affecting milk production traits, a SNP rs located bp upstream of HAL , was found to be significantly associated with milk yield and milk protein yield. The aims of this study were to identify genetic variants in HAL and to test the association between these variants and milk production traits.
Fifteen SNPs were identified within the regions under study of the HAL gene, including three coding mutations, seven intronic mutations, one promoter region mutation, and four 3'UTR mutations.
