Preliminary OBSEA mooring design
The Obsea Cabled Observatory (www.obsea.es) is going
to be expanded with new sea surface sensors such a meteorological
station and a video camera. These new sensors are
going to be installed in a surface buoy with wireless communication
to the Obsea Data Center at SARTI’s Laboratories. The
mooring design and simulations are presented in this paper,
taken into account the marine conditions of the area located in
the Vilanova I la Geltrú coast in the Metiterranean Sea. The simulations
of the static and dynamic behaviour of the anchored
buoy were done with the software OrcaFlex 9.4.Peer ReviewedPostprint (published version

Safety and pharmacokinetic profile of fixed-dose ivermectin with an innovative 18mg tablet in healthy adult volunteers
Ivermectin is a pivotal drug for the control of onchocerciasis and lymphatic filariasis, which is increasingly identified as a useful drug for the control of other Neglected Tropical Diseases. Its role in the treatment of soil transmitted helminthiasis through improved efficacy against Trichuris trichiura in combination with other anthelmintics might accelerate the progress towards breaking transmission. Ivermectin is a derivative of Avermectin B1, and consists of an 80:20 mixture of the equipotent homologous 22,23 dehydro B1a and B1b. Pharmacokinetic characteristics and safety profile of ivermectin allow to explore innovative uses to further expand its utilization through mass drug administration campaigns to improve coverage rates. We conducted a phase I clinical trial with 54 healthy adult volunteers who sequentially received 2 experimental treatments using a new 18 mg ivermectin tablet in a fixed-dose strategy of 18 and 36 mg single dose regimens, compared to the standard, weight based 150-200 μg/kg, regimen. Volunteers were recruited in 3 groups based on body weight. Plasma concentrations of ivermectin were measured through HPLC up to 168 hours post treatment. Safety data showed no significant differences between groups and no serious adverse events: headache was the most frequent adverse event in all treatment groups, none of them severe. Pharmacokinetic parameters showed a half-life between 81 and 91 h in the different treatment groups. When comparing the systemic bioavailability (AUC0t and Cmax) of the reference product (WA-ref) with the other two study groups using fixed doses, we observed an overall increase in AUC0t and Cmax for the two experimental treatments of 18 mg and 36 mg. Body mass index (BMI) and weight were associated with t1/2 and V/F, probably reflecting the high liposolubility of IVM with longer retention times proportional to the presence of more adipose tissue. Systemic exposure to ivermectin (AUC0t or Cmax) was not associated with BMI or weight in our study. These findings contribute to further understand the pharmacokinetic characteristics of ivermectin, highlighting its safety across different dosing regimens. They also correlate with known pharmacokinetic parameters showing stable levels of AUC and Cmax across a wide range of body weights, which justifies the strategy of fix dosing from a pharmacokinetic perspective
Disseny i prototip 3d d’una mà quina transfer
El present projecte tracta de sobre la realització d’una
mà quina trasnfer o de transferència rotativa, per tal de
millorar un procés de mecanització de dues peces, per tal
de millorar la productivitat i l’eficà cia de les peces que
l’empresa ABXXX realitza.
El fet de donar com a solució una mà quina transfer es degut
a que en un estudi que demanà l’empresa, s’arribà a la
conclusió que la millor solució seria la realització d’una
mà quina d’aquest tipus. A part de prendre com a solució, la
mateixa que l’empresa va trobar, s’ha volgut realitzar
aquest tipus de solució per tal que el dia de demà el
procés pugui evolucionar emprant la mateixa maquinaria o la
mateixa metodologia de treball que la donada en aquest
projecte.
La realització d’aquest projecte passa, per veure quin
tipus de solució s’arriba, tot i saber que es realitzarÃ
una mà quina transfer. Al llarg del projecte, s’analitzaran
diversos punts del disseny,ja sigui la resistència dels
materials emprats, l’estudi d’ergonomia, els manteniments
que haurà de tenir i veure com funciona amb la demostració
mitjançant imatges i vÃdeos emprant el mòdul de simulació
kinematica del software emprat pel disseny.
El software que s’empra per poder fer la maqueta digital i
els diversos estudis, anà lisi i simulacions és CATIA v5
R18. Grà cies a aquest programa es pot comprovar d’una forma
visual i amb certa rapidesa, quin serà el comportament dels
materials i de les persones en vers a la mà quina.
Per últim, concloure que la realització d’aquest projecte
ha aportat una quantitat de coneixements nous molt
interessants pel món laboral. I la conclusió no sols és que
la mà quina funcioni i que sigui una solució viable o
possible, sinó que el dia de demà hom si es troba en una
situació similar, pugui afrontar un projecte d’aquest tipus
sense cap problema, ja que queda constà ncia que pot fer-se,
un cop realitzat el present projecte
