  • We analyzed the diet composition of smallmouth argentine Argentina kagoshimae, which were collected via bottom trawl in the South Sea during February, April, August, and October 2021. Their size range was 8.1-21.4 cm total length. A. kagoshimae are mesopelagic carnivores, mainly consuming benthopelagic Euphausiacea and Caridea crustaceans. Polychaetes were the second largest prey component in their diet, which also included small quantities of copepods, amphipods, and arrow worms. Stomach content compositions substantially differed among body size levels in A. kagoshimae. The results of non-metric multidimensional scaling ordination and permutational multivariate analysis of variance of dietary data revealed no significant dietary differences. The results of a graphical analysis of the diet composition showed that A. kagoshimae are specialized feeders characterized by strong individual feeding specialization.

  • Trawl fishing is a major concern worldwide, and there is considerable debate about its impact on marine ecosystems. In this study, we used the vessel monitoring system (VMS) data collected in the southwest Atlantic Ocean from 2016 to 2019 to estimate the fishing effort and trawled area. Spatial distribution of trawl activities according to the latitude and longitude and the hotspots where fishing was concentrated each year were identified. Trawling activities of the Korean vessels were mainly distributed between 40-52°S and 56-63°W. The species caught during the fishing period comprised five Cephalopoda, three Chondrichthyes, ten Osteichthyes, and other fish. The Argentine hake Merluccius hubbsi and Argentine shortfin squid Illex argentinus were the dominant species in the catch.

  • This article has analyzed the limite of integration and discrimination of Paraguayan inmigrants in Argentina. The most numerous collectivity is the Paraguayan inmigrants, with about 325,046 members that reside mainly in the Gran Buenos Aires in 2001. Paraguayan inmigrantes and their families usually undergo abuses by security forces and the over exploitation and the illegal work to a large extent work informally and for low wages. They also point out numerous problems of discrimination with respect to access to the services of public of health, education and housing. For the reason, Argentine government has established the program of Patria Grande in April 17, 2006. This program is that issue a permanent residence and DNI for Latin American immigrants from bordering countries. But the Argentine government does not maintain the program Patria Grande. Paraguayan inmigrants are still situated in the increase of the ilegal work and social insecurity.

  • Fragile-X-syndrome (FXS) is the most common type of inherited cognitive impairment. The underlying molecular alteration consists of a CGG-repeat amplification within the FMR-1 gene. The phenotype is only apparent once a threshold in the number of repeats has been exceeded (full mutation). The aim of this study was to characterize the FMR-1 CGG-repeat status in Argentine patients exhibiting mental retardation. A total of 330 blood samples from patients were analyzed by PCR and Southern blot analysis. Initially, DNA from 78 affected individuals were studied by PCR. Since this method is unable to detect high molecular weight alleles, however, we undertook a second approach using the Southern blotting technique to analyze the CGG repeat number and methylation status. Southern blot analysis showed an altered pattern in 14 out of 240 (6%) unrelated patients, with half of them presenting a mosaic pattern. Eight out of 17 families (47%) showed a (suggest deleting highlight). The characteristic FXS pattern was identified in 8/17 families (47%), and in 4 of these families 25% of the individuals presented with a mosaic model. The expansion from pre-mutation to full mutation was shown to occur both at the pre and post zygotic levels. The detection of FXS mutations has allowed us to offer more informed genetic counseling, prenatal diagnosis and reliable patient follow-up.

  • In prevoius works we have repored phonetic similarities between Japanese and Spanish voweis and syiiabic sounds. (1) (2) (3) (4). In the present communication we explore the relative importance of duration of the consonantal segment to elicit Spanish /l/ - /r/ distinction by native j Japanese talkers. Three Argentine and three trained native Japanese talkers recorded /l-r/ combined with /a/ in VCV sequences. Modifications of consonant duration and vowel context with transitions were m made by editing natural /ala/ sounds. Mixed VCV were produced by combining sounds of both languages. Perceptual tests were produced by combining sounds of both languages perceptual performed presenting the speech material, to native t trained and non trained Japanese listeners. In a tirst sessIOn a d discrimination procedure was applied. The items were arranged in pairs a and listeners Nere told to indicate the pair that sounded different. In the f following session they were asked to identify and type the letter corresponding to each one of the items. Responses arc examined in tenns of critical duration of the interval between vowels. Preliminary results indicate that the duration of intervocalic intervais was a relevant cue for the identification of /l/ and /r/. It seems that to differentiate the two sounds, Japanese listeners required relatively longer interval steps than the argentine suhjects. There was a tendency to conhlse more frequently /l/ for /r/ than viceversa.

  • This Comment explores the ICSID case of CMS Gas Transmission Company v. Argentine Republic, awarded on May 12, 2005. The Part II of this Comment first describes the relevant facts of the case including the some background for readers' understanding and the Part III summaries the claimant's requests and the decisions rendered by the Arbitral Tribunal in the Award. At Part IV, the Comment addresses the issue of determinating laws applicable to the merits of dispute in case that the parties of the case have not chosen a governing law, and at Part V, takes a close look into three main issues of (i) the indirect expropriation of the investment, (ii) the breach of fair and equitable treatment and (iii) the protections under umbrella clauses. In this CMS case, we see first that while the Tribunal affirmed that any indirect expropriation can occur from incidental interference depriving the foreign investor of the use or reasonable-to-be-expected economic benefit even if not necessarily to the obvious benefit of the host State, the Tribunal denied the occurrence of indirect expropriation in this case by holding that the Government of Argentina has not breached the standard of protection laid down in the Treaty. Secondly, however, regarding the issue of fair and equitable treatment, we see that the Tribunal, finding Argentina's breach of obligations, affirmed that the foreign investor can expect the host State to act in a consistent manner, free from ambiguity and totally transparently in its relations with the foreign investor, which can give the foreign investor certain degree of foreseeability. Thirdly and finally, we see that, on base of the effect of the umbrella clause, the Tribunal recognized the obligation of the host State undertaken not to freeze the tariff regime or subject it to price controls and not to alter the basic rules governing contracts between the foreign investor and the host State without the first's written consent. However, the protection under the umbrella clause is available only when there is a specific breach of rights and obligations under BIT or a violation of contract rights protected under BIT.

  • Twenty Landrace and twenty Min piglets, with an average initial body weight of 22.4 kg, were randomly divided into 5 groups with 4 animals per group, within each of the breeds. The piglets were housed in individual concrete pens. Each group of the piglets was fed one of 5 diets. The diets contained either 20% raw Argentine soybeans, 20% processed Argentine soybeans ($118^{\circ}C$ for 7.5 min.), 20% raw Chinese soybeans, 20% processed Chinese soybeans ($118^{\circ}C$ for 7.5 min.) or no soybean products (control diet). Faecal samples were collected on days 6, 7 and 8 of the treatment period. Digestibilities of dietary nutrients were determined with AIA (acid insoluble ash) as a marker. After a 17 day treatment, three piglets were killed from each of the groups. Tissue samples of small and large intestine for light and electron microscopy examination were taken immediately after the opening of abdomen. Then, the weight or size of relevant organs was measured. The results show that the digestibilities of dry matter (DM), crude protein (CP) and fat were higher in Min piglets than in Landrace piglets (p<0.05). The diets containing processed soybeans had a significant higher CP digestibility than the control diet and the diets containing raw soybeans (p<0.05). Landrace piglets had heavier and longer small intestines, heavier kidneys and a lighter spleen than Min piglets (p<0.05). The pancreas of the animals fed the diets containing processed soybeans was heavier than that of the animals fed control diet (p<0.05) and the diets containing raw soybeans. But, the differences between raw and processed soybean diets were not significant. A significant interaction (p<0.05) between diet and pig breed was observed in weight of the small intestine. The Landrace piglets increased the weight in their small intestine when they were fed the diets containing soybeans. In the light micrographs and electron scanning micrographs, it was found that the villi of small intestinal epithelium of animals (especially Landrace piglets) fed the diets containing raw Chinese soybeans were seriously damaged. The transmission electron micrograph showed that a lot of vesicles were located between the small intestinal microvilli of these piglets. The histological examination also indicated that the proportion of goblet cells in villi and crypts in the piglets consuming the control diet was significantly lower (p<0.01 and p<0.02, respectively) than those of the animals consuming the diets containing raw or processed soybeans.

  • This experiment was conducted to determine standardized ileal amino acid digestibility (SIAAD) of commonly used feed ingredients in poultry diets in Pakistan. These feed ingredients included corn, rice broken (RB), rice polishings (RP), wheat bran (WB), sunflower meal (SFM), cottonseed meal (CSM), guar meal (GM), soybean meal (SBM) from India and Argentine and fish meal (FM). The SIAAD of each ingredient was determined in triplicate using 21-days-old broilers. Day-old male broiler chicks (Hubbard${\times}$ Hubbard) were reared on corn-SBM based diet from 1 to 13 days and thereafter birds were fed experimental diets from day 14 to 21. Each diet was fed to 36 birds kept in six replicate cages, each cage had six birds. In cereals, the SIAAD of corn's amino acid (AA) (90.1%) was similar (p>0.05) to RB (89.0%). Isoleucine (97.8%) and lysine (96.9%) were highly digestible AA in corn and RB, respectively. Among cereal-by products, WB's SIAAD (76.9%) was same (p>0.05) as RP (71.9%). Arginine from WB (82.5%) and RP (83.2%) was highly digestible. However, threonine in WB (72.7%) and leucine in RP (69.6%) were the lowest digestible AAs. In plant protein meals, AAs from Argentine-SBM (85.1%) and Indian-SBM (83.4%) had higher (p<0.5) SIAAD than other protein meals. However, SIAAD of SFM (77.1%) and CSM (71.7%) was intermediate while GM (60.3%) exhibited the lowest (p<0.05) SIAAD among all ingredients. Arginine from GM (76.9%), CSM (85.8%), SBM-India (89.5%) and SBM-Argentine (91.5%) was highly digestible from indispensable AAs. In SFM, methionine (91.4%) SIAAD was the greatest. The average SIAAD of FM was 77.6%. Alanine from FM had the highest (84.0%) but cysteine (62.8%) had the lowest SIAAD. In conclusion, cereals i.e. corn and RB had higher (p<0.05) SIAAD of the cereals by-products. The SIAAD of RP and WB was same (p>0.05). The SBM from plant protein meals had higher (p<0.05) SIAAD than other studied feed ingredients. However, the GM had the lowest (p<0.05) SIAAD among protein meals.
