POWER OUTPUT IN WOMEN WEIGHTLIFTERS DURING THE PULL PHASE OF THE SNATCH

The purpose of this study was to determine and describe the power outputs in the snatch lift during the pull phase for American women competing in the national championships. Ten female lifters in the 69 kg class were filmed and analyzed using a Peak5 2D Motion Analysis. Power output values were based on calculations of total work done by the athlete divided by the time (Garhammer, 1993). The total power output values varied from 1095.54 W to 1875.90 W. These values were comparable to figures reported by Garhammer, 1991. Knowing power production values may be important in developing specific types of training programs

Design of small interfaces

Treball desenvolupat dins el marc del programa 'International Design Project Semester'.Many modern devices with different kinds of characteristics have been invading the market in recent years and nowadays the market place is flooded with them.Users are experiencing a storm of new technology and a massive variety of new functions. This current work purposes an innovative approach for the design of small interfaces that can be used by a company to increase their own competitiveness or to develop research studies in an academic domain. With a wide range of research about concepts, interfaces, classification, products history, market tendency, user preferences, guidelines examples and ergonomics in visual and touch channels, was developed a new and effective guideline for small interfaces. With the evaluation of two systems (tablet and smartphone), was possible to do improvements on the design in order to garatee an effective guideline as the final result. The guidelines that we set out to create incorporate research into human anatomy as well as behaviour when using the Tablet. This was done with volunteering test subjects as well as close observation of each user and how they reacted to the tablet and how quickly the adapted and recognised icons within the interface. We also looked into other areas such as the social implications of owning a tablet and the typical demographics of tablet users. This research allowed use to gain a better understanding and insight into the mind of the user so we could deliver an interface to user that was not only what they needed but also one that they wanted to use

A broad-spectrum cloning vector that exists as both an integrated element and a free plasmid in Chlamydia trachomatis

Plasmid transformation of chlamydiae has created new opportunities to investigate host–microbe interactions during chlamydial infections; however, there are still limitations. Plasmid transformation requires a replicon derived from the native Chlamydia plasmid, and these transformations are species-specific. We explored the utility of a broad host-range plasmid, pBBR1MCS-4, to transform chlamydiae, with a goal of simplifying the transformation process. The plasmid was modified to contain chromosomal DNA from C. trachomatis to facilitate homologous recombination. Sequences flanking incA were cloned into the pBBR1MCS-4 vector along with the GFP:CAT cassette from the pSW2-GFP chlamydial shuttle vector. The final plasmid construct, pBVR2, was successfully transformed into C. trachomatis strain L2-434. Chlamydial transformants were analyzed by immunofluorescence microscopy and positive clones were sequentially purified using limiting dilution. PCR and PacBio-based whole genome sequencing were used to determine if the plasmid was maintained within the chromosome or as an episome. PacBio sequencing of the cloned transformants revealed allelic exchange events between the chromosome and plasmid pBVR2 that replaced chromosomal incA with the plasmid GFP:CAT cassette. The data also showed evidence of full integration of the plasmid into the bacterial chromosome. While some plasmids were fully integrated, some were maintained as episomes and could be purified and retransformed into E. coli. Thus, the plasmid can be successfully transformed into chlamydia without a chlamydial origin of replication and can exist in multiple states within a transformed population

Diseño centrado en el usuario para diseñadores industriales

La conexión entre metodologías de la interacción persona-ordenador con métodos tradicionales de diseño es presentada en el contexto del grado de ingeniería del diseño industrial y desarrollo del producto que se imparte en la Escuela Politécnica Superior de Ingeniería de Vilanova i la Geltrú. Un conjunto de asignaturas, un programa de movilidad internacional, profesorado especializado en diseño centrado en el usuario y expertos en entornos industriales y sociales facilitan esta relación. Este trabajo muestra un conjunto de estudios de caso seleccionados que proporciona las claves para la sinergia entre la experiencia de usuario y el diseño de productos-servicios.Peer ReviewedPostprint (published version

An anchored chromosome-scale genome assembly of spinach improves annotation and reveals extensive gene rearrangements in euasterids.

Spinach (Spinacia oleracea L.) is a member of the Caryophyllales family, a basal eudicot asterid that consists of sugar beet (Beta vulgaris L. subsp. vulgaris), quinoa (Chenopodium quinoa Willd.), and amaranth (Amaranthus hypochondriacus L.). With the introduction of baby leaf types, spinach has become a staple food in many homes. Production issues focus on yield, nitrogen-use efficiency and resistance to downy mildew (Peronospora effusa). Although genomes are available for the above species, a chromosome-level assembly exists only for quinoa, allowing for proper annotation and structural analyses to enhance crop improvement. We independently assembled and annotated genomes of the cultivar Viroflay using short-read strategy (Illumina) and long-read strategies (Pacific Biosciences) to develop a chromosome-level, genetically anchored assembly for spinach. Scaffold N50 for the Illumina assembly was 389 kb, whereas that for Pacific BioSciences was 4.43 Mb, representing 911 Mb (93% of the genome) in 221 scaffolds, 80% of which are anchored and oriented on a sequence-based genetic map, also described within this work. The two assemblies were 99.5% collinear. Independent annotation of the two assemblies with the same comprehensive transcriptome dataset show that the quality of the assembly directly affects the annotation with significantly more genes predicted (26,862 vs. 34,877) in the long-read assembly. Analysis of resistance genes confirms a bias in resistant gene motifs more typical of monocots. Evolutionary analysis indicates that Spinacia is a paleohexaploid with a whole-genome triplication followed by extensive gene rearrangements identified in this work. Diversity analysis of 75 lines indicate that variation in genes is ample for hypothesis-driven, genomic-assisted breeding enabled by this work
