Set Up

The present study aimed to set up a short-term protocol for synchronization of follicular wave emergence in sheep, concomitant with estrus synchronization, which would improve ovarian response in assisted reproductive technologies. Administration of a single GnRH dose, concomitant with the insertion of a progesterone-loaded CIDR device, caused regression of gonadotrophin-dependent follicles ≥4 mm in all the GnRH-treated sheep and in around 80% of the controls treated only with CIDR (p < 0.05). Similar percentages of ewes lost all follicles (around 70%) or only the largest one (around 30%) in both groups. Hence, 54.1% and 70% of the sheep lost all large follicles and initiated a new follicular wave in the control and GnRH groups, respectively (p < 0.05). The remaining sheep showed follicles that were still not dependent of luteinizing hormone (LH). So, in fact, all the sheep had non-dominant follicles after treatment. In conclusion, a treatment including GnRH at CIDR insertion would offer a time- and cost-efficient protocol for inducing follicular turnover and synchronizing a new follicular wave at any stage of the estrous cycle.

ABSTRACT The increase in pollution by oil spills in the Baltic has lead to the Minister of Transport to set up a committee with the task to find methods for identifying ships responsible for oil spills. A preliminary study of the oil transport situation in Sweden had shown that the fingerprint method for identification will be difficult to use. The study also showed that microparticles of plastic and metal as tags might be used. In most cases the oil spills in the Baltic are due to pumping out residues mixed with ballast. In the present paper the merits of different methods for tagging these residues, including the cost aspect, are treated as well as identification of recovered oil samples. In a field experiment the oil residues in a tanker were tagged. Some of its tanks were tagged with plastic particles and some with metal particles. The tanks were treated in different ways for cleaning and the oil-water mixtures were then pumped out in the sea under controlled conditions. The different spills were kept inside an enclosure for a fortnight and samples were taken every day. In all analysed samples the tagged substance could be recovered and identified. A plan for testing this method on a larger scale is under preparation.

Abstract In Sao Tome and Principe there are approximately five thousand deaf and hard-of-hearing individuals. Until recently, these people had no language to use among them other than basic home signs used only to communicate with their families. With this communication gap in mind, a project was set up to help them come together in a common space in order to create a dedicated environment for a common sign language to emerge. In less than two years, the first cohort began to sign and to develop a newly emerging sign language – the Sao Tome and Principe Sign Language (LGSTP). Signs were elicited by means of drawings and pictures and recorded from the beginning of the project. The emergent structures of signs in this new language were compared with those reported for other emergent sign languages such as the Al-Sayyid Bedouin Sign Language and the Lengua de Señas de Nicaragua, and several similarities were found at the first stage. In this preliminary study on the emergence of LGSTP, it was observed that, in its first stage, signs are mostly iconic and exhibit a greater involvement of the articulators and a larger signing space when compared with subsequent stages of LGSTP emergence and with other sign languages. Although holistic signs are the prevalent structure, compounding seems to be emerging. At this stage of emergence, OSV seems to be the predominant syntactic structure of LGSTP. Yet the data suggest that new signers exhibit difficulties in syntactic constructions with two arguments.

This study describes the in vitro testing of elastomeric modules. Measurements were first made from study models to establish the clinical distance over which modules are used for canine retraction. From this preliminary study, a typodont, banded with 0·018” × 0·025” standard edgewise brackets, was set up with the canin-molar distance at 28 mm. Modules for canine retraction were then fitted by 11 clinicians. The applied force ranged from 125 to 310 g (221±51 g). A similar, but more extensive study using six different types of modules and two clinician groups (experienced and less experienced clinicians) was then undertaken. Mean force values for different module types ranged from 195±45 g to 318±90 g. There was no statistically significant difference between the force values applied by experienced and less experienced clinicians

The marathon is the most classic Olympic running event. In several cities worldwide it has become very popular with participation increasing during the last 20 years, particularly by Master Athletes. There are evidences that long-distance running could provide considerable health benefits for older runners, specifically risk reduction of cardiovascular diseases, cancer, diabetes, depression, and falls. Several studies have focused on the distribution of participants and their performance on famous marathons such as those of Berlin, Boston and New York. In this preliminary study we have analyzed data from several editions of the Venice marathon, a famous Italian race that attracts people from every corner of the world. The Venice marathon is listed in Abbott World Marathon Majors Wanda Age Group World Ranking and is Bronze Label certificated by IAAF, and Gold Label by FIDAL. The marathon starts outside Venice near Stra, then runs along the Brenta Riviera to Venice where the runners cross the canals over floating bridges set up for the race. For this study we analyzed data of the Venice marathon describing gender distribution in 17 editions (2003-2019), but groups of age-categories and their nationality only in 13 editions from 2007 to 2019. The analysis shows a steady increase in female participation, from 2003 to 2019.

In order to obtain culture of Saccharomyces cerevisiae which has the highest ethanol tolerance and can produce high yield of ethanol as well a study of mutation has been begun. Mutation experiment conducted by continuos adaptation on a chemostat was initiated with a preliminary study of screening of alcohol-tolerant yeast.  The procedures of screening of alcohol-tolerant yeast continued by optimation of substrate concentration and determination of its critical pH. Recently, the Laboratory of Microbiology and Bioprocess Technology Faculty of industrial Technology ITB has various kind of yeasts that have been obtained or isolated from various sources. The best culture for mutation has been chosen as the most ethanol tolerant one. By screening them on two types of experiment, has been obtained that culture Saccharomyces cerevisiae R-60 gave the highest external ethanol and internal ethanol   as well. External ethanol means the ethanol that was purposely added to the cultivation media, while the internal ethanol means the ethanol that was resulted from fermentation of the yeast.  As preparation for mutation experiment, the determination of optimum substrate concentration which can give the highest amount of Saccharomyces cerevisiae cells has been carried out. In order to set up the control point of culture viability on chemostat, the critical pH of choosed culture have also been obtained. The result of the experiment gave optimum glucose concentration of 18.6% and critical pH of 4.5 to 3.8, were to be applied in the mutation process.Keywords: Cultivation; Fermentation; Saccharomyces cerevisiae; Screening; YeastAbstrakPenelitian untuk mendapatkan kultur Saccharomyces cerevisiae yang mempunyai toleransi etanol yang tinggi dan dapat menghasilkan perolehan etanol yang juga tinggi telah dilangsungkan.
