New records of the pampas cat, leopardus colocola (Molina, 1782) (mammalia, carnivora, felidae), from the Chaco ecoregion raise questions about its status in Argentina

Leopardus colocola (Molina, 1782) is a poorly known small felid distributed throughout a large portion of South America, reported as extinct in the Pampas of Argentina, and absent from a large portion of the Argentine Dry Chaco. We compile data from the field and national collections to report new occurrence records of this species from the Dry Chaco of Argentina and update its distribution. We discuss the need of further assessments of the distribution of this species in the light of ongoing land-use changes in the area.Fil: Nanni, Ana Sofía. Universidad Nacional de Tucumán.

A VLBI experiment using a remote atomic clock via a coherent fibre link

We describe a VLBI experiment in which, for the first time, the clock reference is delivered from a National Metrology Institute to a radio telescope using a coherent fibre link 550 km long. The experiment consisted of a 24-hours long geodetic campaign, performed by a network of European telescopes; in one of those (Medicina, Italy) the local clock was alternated with a signal generated from an optical comb slaved to a fibre-disseminated optical signal. The quality of the results obtained with this facility and with the local clock is similar: interferometric fringes were detected throughout the whole 24-hours period and it was possible to obtain a solution whose residuals are comparable to those obtained with the local clock. These results encourage further investigation of the ultimate VLBI performances achievable using fibre dissemination at the highest precision of state-of-the-art atomic clocks

Assessment of Body Composition and Physical Performance of Young Soccer Players: Differences According to the Competitive Level

Simple Summary In recent years, soccer teams require greater physical and technical-tactical capabilities from not to younger players, especially in elite team. Although dribble and kicking skills, strength, endurance, speed, and agility abilities are the most relevant features, it is not clear whether anthropometric and body composition aspects could be considered appropriate talent characteristics in soccer players. In addition, it rests unclear which are the principal differences, when they appear, and what metrics discriminate between elite and non-elite teams. The main aim of this study is to compare anthropometric, body composition and physical performance between and within four juvenile categories of two (elite and non-elite) soccer teams and investigates factors that better discriminate among two teams. Despite the physical performance results as the most relevant factor in discriminating among the two soccer societies, the elite players report better anthropometric and body characteristics, especially in the youngest categories. Soccer is a multifactorial sport, in which players are expected to possess well developed physical, psychological, technical, and tactical skills. Thus, the anthropometric and fitness measures play a determinant role and could vary according to the competitive level. Therefore, the present study aimed to verify differences in body composition and physical performance between two soccer team. 162 young soccer players (from the Under 12 to Under 15 age categories; age: 13.01 +/- 1.15 years) of different competitive levels (elite-n = 98 and non-elite-n = 64) were recruited. Anthropometric characteristics (height, weight, lengths, widths, circumferences, and skinfold thicknesses (SK)), bioelectrical impedance, physical performance test as countermovement jump (CMJ), 15 m straight-line sprints, Yo-Yo Intermittent Recovery Test Level 1 (Yo-Yo), and 20 + 20 m repeated-sprint ability (RSA)) were carried out. In addition, Body mass index (BMI), body composition parameters (percentage of fat mass (%F), Fat mass (FM, kg), and Fat-free mass (FFM, kg)) and the areas of the upper arm, calf and thigh were calculated, and the Bioelectric Impedance Vector Analysis (BIVA) procedures were applied. In addition, a linear discriminant analysis was assessed to determine which factors better discriminate between an elite and non-elite football team. Many differences were observed in body composition between and within each football team's category, especially in triceps SK (p < 0.05), %F (p < 0.05), and all performance tests (p < 0.01). The canonical correlation was 0.717 (F-(7,F-128) = 19.37, p < 0.0001), and the coefficients that better discriminated between two teams were 15 m sprint (-2.39), RSA (1-26), suprailiac SK (-0.5) and CMJ (-0.45). Elite soccer team players present a better body composition and greater physical efficiency. In addition, BIVA outcome could be a relevant selection criterion to scout among younger soccer players

Survey Hardware IT Scientifico INAF

Si è più volte ricordato che tra la strumentazione avanzata per l’osservazione dell’Universo un ruolo essenziale, e non secondario, va allo strumento IT nel suo insieme. Questo strumento si compone di diverse componenti, dal hardware al software fino al networking tra il “capitale umano”. Armonizzare, sviluppare ed integrare adeguatamente le varie componenti ha permesso e permette ai progetti di ottenere un livello di eccellenza nazionale ed internazionale, ma la loro armonizzazione sta diventando complicata soprattutto in vista dei grandi progetti e della sostenibilità dell’infrastruttura. L’ICT dell’INAF fino al 2021 ha cercato di valorizzare l’esperienza acquisita nei vari campi IT facendo da stimolo nella creazione di gruppi di lavoro sulle varie tematiche, organizzando corsi su strumenti specifici, linguaggi di programmazione, e sviluppando un prototipo organizzativo per una infrastruttura più ampia che non fosse dedicata al singolo progetto, ma che permettesse l’ottimizzazione, soprattutto del capitale umano, necessario per i singoli progetti e per le attività di “long tail of science”. Data la richiesta di riorganizzazione l’IT in INAF, si e’ voluto fare uno snapshoot della situazione attuale, e di quella di sicura acquisizione, in modo da poter meglio organizzare i prossimi passi infrastrutturali. Si ‘e quindi richiesta la collaborazione dei direttori delle Strutture, dei responsabili dei progetti e della comunità tutta affinché compili in modo adeguato le schede della loro infrastruttura scientifica IT sopra un certo livello di core e Storage (indicativamente sopra i 100 core e i 100 TB di storage). Il disegno che ne risulta è una mappa frammentata di HW, in parte derivante anche da infrastruttura non direttamente dell’INAF. Non è lo scopo di questo documento quello di voler estrapolare conclusioni, ma serve per tenere traccia dell’infrastruttura IT, e quindi si pensa di aggiornarlo regolarmente

Realizzazione di un nuovo sito web per l’INAF - Istituto di Radioastronomia

Questo report illustra l'attivita` del gruppo di lavoro incaricato della progettazione e sviluppo del nuovo sito web dell'INAF - Istituto di Radioastronomia. L'utilizzo di tecnologie di sviluppo web basate su CMS ha consentito di superare le difficolta` nell'aggiornamento e gestione del precedente sito basato su pagine html statiche. Con il nuovo approccio si è ottenuto da un lato un notevole miglioramento dell'aspetto grafico e della coerenza tra le pagine, dall’altro una notevole semplificazione nella produzione e nell’aggiornamento delle pagine stesse. Cio` consentira` ai diversi gruppi di ricerca, servizi e uffici di farsi carico delle pagine di competenza e di poter facilmente apportare modifiche ai contenuti via via che queste si renderanno necessarie, garantendo allo stesso tempo una maggiore sicurezza informatica. Nel report vengono descritte le varie fasi dell'attivita` del gruppo di lavoro: dalla iniziale identificazione delle linee guida e progettazione di struttura e contenuti, sino alla realizzazione vera e propria delle pagine web e ai successivi step di verifica conclusi con la pubblicazione online del sito

Grasslands and Open Savannas of the Dry Chaco

The Dry Chaco is mostly known as a forested ecosystem. However it includes natural grasslands, savannas, scrublands, and wetlands. With one of the highest global deforestation rates in the last two decades and only 12% of the area protected, the concern about land-use change in this ecoregion has raised exponentially; but conservation initiatives developed in last years almost exclusively targeted forests whereas natural grasslands and savannas remain as neglected ecosystem within scientific and governmental agendas. While currently the distribution of natural grassland and savanna area encompasses over 20,000 km2, historical records and spatial models indicate that natural grassland and savannas were more widespread in pre-European era. Two main reasons drove this reduction in natural grasslands and savannas: woody encroachment by fire suppression and overgrazing, and conversion to agriculture and implanted pastures. In this article, through a combination of analyzes and bibliographic revisions, we describe biotic and abiotic components of natural grassland and savannas of the Dry Chaco. We also present the current distribution and conservation status of these ecosystems, and describe the process of change and the ecological consequences for biogeochemical cycles and biologic interactions. To provide basis for management, we estimate current grazing stocking rates on natural grasslands and savannas of Argentine Dry Chaco and we propose an alternative approach to sustainably intensify the use of these ecosystems and improve cattle rancher livelihoods. Despite the existent knowledge about natural grasslands and savannas in the region, we believe that is necessary to motivate the scientific community and national institutions to increase efforts to reconcile the restoration and conservation of these particular rangelands.Fil: Fernández, Pedro.
