Revision of the Asian spider genus Pandava Lehtinen (Araneae: Titanoecidae): description of five new species and first record of Titanoecidae from Africa

The spider genus Pandava Lehtinen previously included two species, P. laminata (Thorell) and P. hunanensis Yin and Bao, known from Asia and the Pacific Islands. The genus is diagnosed by the reduced tegular process on the male palp and the anterior position of the copulatory openings on the female epigynum. In this paper, we present updated descriptions for the known species of Pandava and we describe five new species: Pandava shiva sp. nov. from Pakistan, Pandava sarasvati sp. nov. from Myanmar; Pandava ganesha sp. nov., Pandava kama sp. nov. and Pandava ganga sp. nov., all from India. We also update the generic distribution including the first records of Titanoecidae from Africa.

Educação do campo e alternância :reflexões sobre uma experiência na Transamazônica/Pará

The study theme is the Rural Familiar House Program (RFHP), through the Rural Familiar House of Uruará-PA city (URFH), from 2000 to 2005. It is considered as base the education offered to the field young people, in the modality of basic education by alternation methodology between the Familiar and School Times in the two first from 5th to 8th grade classrooms. From the argument about the understanding importance and need of knowledge transmission and construction to be established in the inter-section between general references of the social reality and the subjective ones. It constitutes an educative work that both values domain of knowing and the creative capacity of each pupil. Considering that the greatest aim of the education is the human being emancipation, this thematic for the development of the documentary and field research was defined with the delimitated thematic for the educative practice-proposal in alternation, choosing the Program of the RFHs as the reference to carry out an analysis which considered fruitful in the articulation between education and educative work. This study had the objective to contribute for the debate concerning the alternation and to understand presuposals and educative practice of the RFHs what its importance for the young people and its relation with the field educational policy. For this, it was used, mainly, from analytical references of authors, such as Williams, Gramsci, Adorno, Freire, Shiva, Soares, Molina, Tonet, et. all, all were also important for the construction of this work. The studied documentary sources, as well as the verbal ones the actors also interviewed had allowed, in irreplaceable way and significantly, a critical analysis on the pedagogical proposals and the articulation among school, familiar work and education, which was carried out in the formation of URFH, the sessions of alternation between Time School and Time Family. The results are scored with the chapter construction, as they had presented themselves in several sources and the reading which was made. A reading that signals for the affirmation which is possible to overtake the emphasis on technicality, mediated in the practice-theory-practice relation, still present in the alternation, and, thus, to be able to make an educative work that intends to contribute for the young people education with capacity of being, thinking and to act actually as subjects of their history

Tecniche di risparmio idrico a livello locale e mondiale. Approfondimento sulle buone pratiche agricole per un uso sostenibile dell'acqua

Oltre un miliardo di persone non ha oggi accesso all’acqua potabile; più di due miliardi è il numero di coloro che vivono in condizioni igienico-sanitarie realmente proibitive. Sono 80 i paesi nel mondo (con il 40% della popolazione totale) in cui si riscontra difficoltà di approvvigionamento e presenza di risorse idriche che mancano dei requisiti che dovrebbero essere assicurati per la tutela della salute: quotidianamente e sistematicamente il diritto di accesso all’acqua, che nessun individuo dovrebbe vedersi negato, viene violato. Scarsità di acqua e non omogenea distribuzione sulla superficie terrestre sono fattori che concorrono alla crisi della risorsa, cui contribuiscono processsi di natura ambientale (cambiamenti climatici, desertificazione), di natura economica (le sorti dell’industria agroalimentare, la globalizzazione degli scambi, il bisogno crescente di energia), di natura sociale (migrazioni, urbanizzazione, crescita demografica, epidemie), di natura culturale (passaggio dal rurale all’urbano, dall’agricoltura di sussistenza a quella di profitto). Nell’ottica di uno sviluppo sostenibile un aumento indiscriminato dell’offerta non può costituire soluzione al continuo incremento della domanda di acqua. Si rende pertanto necessaria la definizione di politiche e strumenti di cambiamento nei modelli di consumo e nella pianificazione che consentano una riduzione degli squilibri nella distribuzione e nella gestione della risorsa a livello domestico e civile, industriale, agricolo. L’uso efficiente, e quindi sostenibile, dell’acqua è da perseguirsi secondo le modalità: • Risparmio, inteso come minore consumo di acqua all’inizio del ciclo. • Riciclo dell’acqua in circuito chiuso, inteso come riuso dell’acqua di scarico, o uso multiplo dell’acqua. Una idonea utilizzazione dipende da una idonea progettazione, che abbia come finalità: • La destinazione in via prioritaria delle fonti e delle risorse di più elevata qualità agli usi idropotabili, con una graduale sostituzione del consumo per altri usi con risorse di minore pregio. • La regolamentazione dell’uso delle acque sotterranee, mediante la limitazione del ricorso all’impiego di pozzi solo in mancanza di forniture alternative per uso civile, industriale, agricolo. • L’incentivazione ad un uso razionale della risorsa, anche mediante l’attuazione di idonee politiche tariffarie. • L’aumento dell’efficienza delle reti di adduzione e distribuzione, sia civili che irrigue. • La promozione di uso efficiente, riciclo e recupero di acqua nell’industria. • Il miglioramento dell’efficienza ed efficacia delle tecniche di irrigazione. • La promozione del riutilizzo delle acque nei vari settori. • La diffusione nella pratica domestica di apparati e tecnologie progettati per la riduzione degli sprechi e dei consumi di acqua. In ambito agricolo la necessità di un uso parsimonioso della risorsa impone il miglioramento dell’efficienza irrigua, pari appena al 40%. La regione Emilia Romagna a livello locale, Israele a livello internazionale, forniscono ottimi esempi in termini di efficacia dei sistemi di trasporto e di distribuzione, di buona manutenzione delle strutture. Possibili soluzioni verso le quali orientare la ricerca a livello mondiale per arginare la progressiva riduzione delle riserve idriche sono: • Revisione dei costi idrici. • Recupero delle riserve idriche. • Raccolta dell’acqua piovana. • Miglioramento degli impianti di distribuzione idrica. • Scelta di metodi di coltivazione idonei alle caratteristiche locali. • Scelta di colture a basso fabbisogno idrico. • Conservazione della risorsa attraverso un sistema di irrigazione efficiente. • Opere di desalinizzazione. • Trasferimento idrico su vasta scala da un’area all’altra. Si tratta di tecniche la cui attuazione può incrementare la disponibilità media pro capite di acqua, in particolare di coloro i quali non ne posseggono in quantità sufficiente per bere o sono privi di sistemi igienico-sanitari sufficienti.

First results from a Swiss level I trauma centre participating in the UK Trauma Audit and Research Network (TARN): Prospective cohort study

QUESTIONS UNDER STUDY: Patient characteristics and risk factors for death of Swiss trauma patients in the Trauma Audit and Research Network (TARN). METHODS: Descriptive analysis of trauma patients (≥16 years) admitted to a level I trauma centre in Switzerland (September 1, 2009 to August 31, 2010) and entered into TARN. Multivariable logistic regression analysis was used to identify predictors of 30-day mortality. RESULTS: Of 458 patients 71% were male. The median age was 50.5 years (inter-quartile range [IQR] 32.2-67.7), median Injury Severity Score (ISS) was 14 (IQR 9-20) and median Glasgow Coma Score (GCS) was 15 (IQR 14-15). The ISS was >15 for 47%, and 14% had an ISS >25. A total of 17 patients (3.7%) died within 30 days of trauma. All deaths were in patients with ISS >15. Most injuries were due to falls <2 m (35%) or road traffic accidents (29%). Injuries to the head (39%) were followed by injuries to the lower limbs (33%), spine (28%) and chest (27%). The time of admission peaked between 12:00 and 22:00, with a second peak between 00:00 and 02:00. A total of 64% of patients were admitted directly to our trauma centre. The median time to CT was 30 min (IQR 18-54 min). Using multivariable regression analysis, the predictors of mortality were older age, higher ISS and lower GCS. CONCLUSIONS: Characteristics of Swiss trauma patients derived from TARN were described for the first time, providing a detailed overview of the institutional trauma population. Based on these results, patient management and hospital resources (e.g. triage of patients, time to CT, staffing during night shifts) could be evaluated as a further step.

Lazy lips: hyperkalemia and acute tetraparesis-a case report from an urban emergency department.

A 58-year-old male patient was admitted to our emergency department at a large university hospital due to acute onset of general weakness. It was reported that the patient was bradycardic at 30/min and felt an increasing weakness of the limbs. At admission to the emergency department, the patient was not feeling any discomfort and denied dyspnoea or pain. The primary examination of the nervous system showed the cerebral nerves II-XII intact, muscle strength of the lower extremities was 4/5, and a minimal sensory loss of the left hemisphere was found. In addition, the patient complained about lazy lips. During ongoing examinations, the patient developed again symptomatic bradycardia, accompanied by complete tetraplegia. The following blood test showed severe hyperkalemia probably induced by use of aldosterone antagonists as the cause of the patient's neurologic symptoms. Hyperkalemia is a rare but treatable cause of acute paralysis that requires immediate treatment. Late diagnosis can delay appropriate treatment leading to cardiac arrhythmias and arrest.

If hunters end up in the emergency room: a retrospective analysis of hunting injuries in a swiss emergency department.

Aim. to characterize the mechanisms, patterns, and outcomes of nonfatal hunting-related injuries in patients presenting to Bern University Hospital, Switzerland, and compare these to reports of hunting injuries worldwide. Methods. patients presenting with hunting-related injuries to the Emergency Department at Bern University hospital from 2000 to 2014 were identified by retrospectively searching the department database using the keyword "hunt." Each case was analyzed in terms of the patient age and gender, the mechanism and pattern of injury, and management and patient follow-up. Results. 19 patients were identified. 16 were male with a mean age of 50 years (range: 16-74). Mechanisms of injury included firearm-related injuries, falls, and knife wounds. The most common patterns of injury were head injuries (7), followed by injuries to the upper (5) or lower limb (5) and trunk (2). Over half of the patients were admitted, and nine required emergency surgery. Conclusion. Nonfatal hunting accidents in Bern, Switzerland, are largely caused by firearms and falls and tend to occur in male hunters with a mean age of 50 years. The most common patterns of injury are orthopedic and head injuries, often requiring surgery. These findings are consistent with international studies of nonfatal hunting accidents.

Risk factors and inflammatory markers in pouchitis

Individuals who do not respond to medical therapy for ulcerative colitis (UC) often undergo proctocolectomy followed by ileal-pouch anal anastomosis (IPAA) in hopes of resolving symptoms associated with UC. Inflammation of the ileal pouch, better known as pouchitis, is the most common complication of the IPAA procedure. The causes and development of pouchitis is not well understood. To better understand pathogenesis of pouchitis, pouch aspirates of patients having undergone IPAA were quantitatively analyzed for fecal IL-8, IL-17, and IL-23 levels. According to published literature IL-8 has been linked to pouchitis whereas IL-17 and IL-23 are associated with intestinal inflammation. The study had 80 participants, 33 patients diagnosed with Crohn's Disease (CD) of the pouch, 19 patients diagnosed with pouchitis, and 28 diagnosed with having normal pouches. Patient characteristics and histopathological findings for all patients were noted and statistically compared in addition to fecal cytokine levels. This study supported previous literature that IL-8 production was associated with pouch inflammation. However, IL-17 and IL-23 levels in both CD of the pouch and pouchitis were not significantly different to the levels noted in normal pouch.^

A low-latitude Upper Pleistocene oxygen isotope stack

Below oxygen isotope stage 16, the orbitally derived time-scale developed by Shackleton et al. (1990) from ODP site 677 in the equatorial Pacific differs significantly from previous ones (e.g. Kominz and Pisias, 1979 doi:10.1126/science.204.4389.171; Morley and Hays, 1981 doi:10.1016/0012-821X(81)90034-0, Imbrie et al. 1984), yielding estimated ages for the last Earth magnetic reversals that are 5-7% older than the K/Ar values (Mankinen and Dalrymple, 1979 doi:10.1029/JB084iB02p00615; Berggren et al., 1985; Harland and Armstrong, 1989) but are in good agreement with recent Ar/Ar dating (Baksi et al., 1991; 1992 doi:10.1126/science.256.5055.356; Spell and McDougall, 1992 doi:10.1029/92GL01125). These results suggest that in the lower Brunhes and upper Matuyama chronozones most deep-sea climatic records retrieved so far apparently missed or misinterpreted several oscillations predicted by the astronomical theory of climate. To test this hypothesis, we studied a high-resolution oxygen isotope record from giant piston core MD900963 (Maldives area, tropical Indian Ocean) in which precession-related oscillations in delta18O are particularly well expressed, owing to the superimposition of a local salinity signal on the global ice volume signal (Rostek et al., 1993 doi:10.1038/364319a0). Three additional precession-related cycles are observed in oxygen isotope stages 17 and 18 of core MD900963, compared to the SPECMAP composite curves (Imbrie et al., 1984; Prell et al., 1986 doi:10.1029/PA001i002p00137), and stage 21 clearly presents three precession oscillations, as predicted by Shackleton et al. (1990). The precession peaks found in the delta18O record from core MD900963 are in excellent agreement with climatic oscillations predicted by the astronomical theory of climate. Our delta18O record therefore permits the development of an accurate astronomical time-scale. Based on our age model, the Brunhes-Matuyama reversal is dated at 775 +/- 10 ka, in good agreement with the age estimate of 780 ka obtained by Shackleton et al. (1990) and recent radiochronological Ar/Ar datings on lavas (Baksi et al., 1991; 1992; Spell and McDougall, 1992). We developed a new low-latitude, Upper Pleistocene delta18O reference record by stacking and tuning the delta18O records from core MD900963 and site 677 to orbital forcing functions.
