Abstract In the paper we discuss migration dynamics, biometry and stopover ecology of Ruff (Philomachus pugnax Linnaeus, 1758) in the Cholgini ornithological reserve. Also the observations, made in other regions of the western Ukraine, were used in the analysis. Th e base materials for this paper were collected during 1995-2012 by West-Ukrainian ornithological station, by conducting regular bird counts, ringing and taking measurements of migrating waders using standard methods. During Ruff spring migration two major waves of passage occured: the first one is from the end of March till early April and the second - from the end of April to the end of May. Th e average number of a flock was equal 12 individuals. In the autumn passage dynamics of two waves can also be seen. Th e fist wave is observed in July with the peak in the middle of month. Second wave occurs in August and in fist two decades of September, with maximum bird numbers in the end of August. Th e passage dynamic of Ruff in the Cholgini reserve is very similar to the dynamic in other continental staging sites. Significant difference was found in the wing length between the adult and juvenile Ruff s. Th e potential flight range of juvenile females was 3236 km, juvenile males - 2380 km, adult females - 2740 km.

Wing lengths of Clamorous Reed Warblers Acrocephalus stentoreus in Israel Wing length measurements taken from first-year, pre- and post-moulting (annual, complete) Clamorous Reed Warblers were recorded at a site in northern Israel. The resulting data set was examined using a time-series of residuals (CUSUM). Results from this analysis can explain the reported heterogeneity found in a comparable data set by Merom et al. (1999). Further observations made in their paper are rebutted: (1) an implied assumption that Reed Warbler (Acrocephalus scirpaceus) spring migration in Israel ends by 1 May is contrary to other publications; (2) the late autumn occurence in N Israel of longer-winged 1st cal. yr. Reed Warblers, unconvincingly explained as either delayed migration by larger individuals or post fledging feather growth, is most likely due to birds from different provenances origins moving at different seasons; (3) growth during adulthood in Reed Warbler is not a new discovery, though presented as such.

Infra-popliteal veins include the tibial and peroneal veins, as well as the soleal and gastrocnemial veins collectively known as the calf muscle veins (CMVs). Acute infra-popliteal deep venous thrombi (DVTs) are often considered insignificant with regard to the risk of pulmonary embolism (PE). A retrospective review of 4035 consecutive lower extremity venous duplex scans were made in 3146 hospital patients at our Intersocietal Commission for the Accreditation of Vascular Laboratories (ICAVL)-accredited vascular lab. Seven hundred sixteen (17.7%) duplex scans were positive for acute DVTs, and 112 (2.8%) were associated with PEs. The breakdown of positive duplexes for acute DVTs was as follows: 202 (28.2%) isolated femoral-popliteal DVTs with PE in 23 (11.4%), 304 (42.5%) isolated infra-popliteal DVTs with PE in 24 (7.9%) and 210 (29.3%) multilevel DVTs involving both vein segments (femoral-popliteal and infra-popliteal) with PE in 38 (18.1%). Of the 304 isolated acute infra-popliteal DVTs, 207 (68.1%) were isolated CMV DVTs with evidence of PE in 12 (5.8%). No statistically significant difference ( P = 0.27) in the risk of PE between isolated femoral-popliteal and isolated infra-popliteal DVTs was noted. A significant number of patients (5.8%) with isolated CMV DVTs developed PE. Lower limb venous scans for DVTs should evaluate the infra-popliteal veins. Hospitalized patients with infra-popliteal DVTs should receive anticoagulation.

Objectives The objectives were to examine the density, bubble size distribution and durability of sodium tetradecyl sulphate foam and the consistency of production of foam by a number of different operators using the Tessari method. Methods 1% and 3% sodium tetradecyl sulphate sclerosant foam was produced by an experienced operator and a group of inexperienced operators using either a 1:3 or 1:4 liquid:air ratio and the Tessari method. The foam density, bubble size distribution and foam durability were measured on freshly prepared foam from each operator. Results The foam density measurements were similar for each of the 1:3 preparations and for each of the 1:4 preparations but not affected by the sclerosant concentration. The bubble size for all preparations were very small immediately after preparation but progressively coalesced to become a micro-foam (<250 µm) after the first 30 s up until 2 min. Both the 1% and 3% solution foams developed liquid more rapidly when made in a 1:3 ratio (37 s) than in a 1:4 ratio (45 s) but all combinations took similar times to reach 0.4 ml liquid formation. For all the experiments, there was no statistical significant difference between operators. Conclusions The Tessari method of foam production for sodium tetradecyl sulphate sclerosant is consistent and reproducible even when made by inexperienced operators. The best quality foam with micro bubbles should be used within the first minute after production.

This study assessed differences in response rates to a series of three-wave mail surveys when amiable or insistently worded postcards were the third wave of the mailing. Three studies were conducted; one with a sample of 600 health commissioners, one with a sample of 680 vascular nurses, and one with 600 elementary school secretaries. The combined response rates for the first and second wave mailings were 65.8%, 67.6%, and 62.4%, respectively. A total of 308 amiable and 308 insistent postcards were sent randomly to nonrespondents as the third wave mailing. Overall, there were 41 amiable and 52 insistent postcards returned, not significantly different by chi-square test. However, a separate chi-square test for one of the three studies, the nurses' study, did find a significant difference in favor of the insistently worded postcards.

Three surveys were made in 1963 and five in 1964 in the area of the English Channel between the English and French coasts and between 3° 40' W and 5°10' W. This area had been surveyed in 1961 and 1962. Temperature and salinity were determined at o, to and 50 m and phosphate silicate and nitrate at 10 and 50 m. The results are presented graphically. Temperature and salinity were compared with Lumby's 25–year averages. The year 1963 started with unusually low temperatures and salinities higher than average. Temperature remained low in the spring, but salinity decreased. The year 1964 started with temperatures and salinities above normal, but during the rest of the year values were close to average. Nitrate in January 1964 was higher than in January 1963. Analyses of suspended matter at 12m were made for carbon, nitrogen and phosphorus on most surveys, and mean values for the whole area are given. Suspended carbon was 67 /ig C/l. in January 1963 and 51 /*g C/l. in January 1964, a significant difference. Increases in sus-pended carbon, nitrogen and phosphorus were found in spring and summer 1964.

Background: Hospitals have constituted the limiting resource of the healthcare systems for the management of the COVID-19 pandemic. As the pandemic progressed, knowledge of the disease improved, and healthcare systems were expected to be more adapted to provide a more efficient response. The objective of this research was to compare the flow of COVID-19 patients in emergency rooms and hospital wards, between the pandemic's first and second waves at the University Hospital of Vall d’Hebron (Barcelona, Spain), and to compare the profiles, severity and mortality of COVID-19 patients between the two waves. Methods: A retrospective observational analysis of COVID-19 patients attending the hospital from February 24 to April 26, 2020 (first wave) and from July 24, 2020, to May 18, 2021 (second wave) was carried out. We analysed the data of the electronic medical records on patient demographics, comorbidity, severity, and mortality. Results: The daily number of COVID-19 patients entering the emergency rooms (ER) dropped by 65% during the second wave compared to the first wave. During the second wave, patients entering the ER were significantly younger (61 against 63 years old p<0.001) and less severely affected (39% against 48% with a triage level of resuscitation or emergency; p<0.001). ER mortality declined during the second wave (1% against 2%; p<0.000). The daily number of hospitalised COVID-19 patients dropped by 75% during the second wave. Those hospitalised during the second wave were more severely affected (20% against 10%; p<0.001) and were referred to the intensive care unit (ICU) more frequently (21% against 15%; p<0.001). Inpatient mortality showed no significant difference between the two waves. Conclusions: Changes in the flow, severity and mortality of COVID-19 patients entering this tertiary hospital during the two waves may reflect a better adaptation of the health care system and the improvement of knowledge on the disease.

ABSTRACT: This work aimed to evaluate the effect of platelet-rich plasma (PRP) on advancement skin flaps in dogs regarding improvement of vascularization, with focus on increasing its viable area, since there are reports that it is a potential angiogenesis stimulator. The experimental group was composed of eight adult bitches, in which two advancement skin flaps were made in the ventral abdominal region. No product was applied in the control flap (CF), while PRP was used in the contralateral flap, called treated flap (TF). The areas were clinically evaluated every two days until the 7th postoperative day regarding skin color and presence of necrosis. At 10 days, both flaps were removed and submitted to histological examination and blood vessel morphometry. The vessels counted in each group were statistically analyzed by the F-test at 1% probability. Results showed no significant difference in macroscopic changes in the wound, or CF and TF vascularization, thus suggesting that PRP gel did not improve advancement skin flap angiogenesis in bitches under the experimental conditions in which this research was developed.

ABSTRACT The iconic image of Rosie the Riveter played an important role in American patriotic ideological processes during World War II. Aimed at the recruitment of women for wartime work, particularly in factories and traditionally masculine occupations, this representation of a woman in overalls and head scarf, with sleeves rolled up, showing her bicep and balled fist, declaring 'We can do it', has been a contentious point of discussion for its significance in feminist agendas since its first appearance. While building on, and playing to, the suffrage agendas of first wave feminism, the popular image of Rosie was transcended by second wave concerns about depictions of women in the workplace, such as those in films like Norma Rae (Ritt 1979), Silkwood (Nichols 1983), North Country (Caro 2005) and Made in Dagenheim (Cole 2010). But Rosie is making a comeback. The image has recently been appropriated in various ways and for various purposes - naively, ironically, satirically, as bricolage, pastiche and in sexualised portrayals - to represent contemporary women's issues and concerns, as well as arguably forming part of a backlash culture against feminism. Contemporary depictions have, for example, ranged from Hilary Clinton, Sarah Palin, Michelle Obama, Malala Yousafzai and Beyoncé. This paper considers the development and transformation of the image of Rosie the Riveter and its contradictory (re)-appropriations in various contemporary popular cultural discourses. Keywords: feminist expression, Michel Foucault, gender roles, popular culture, Rosie the Riveter.

ABSTRACTObjectivesPatients often bring their smartphones to the emergency department (ED) and want to record their procedures. There was no clear ED recording policy in the Saskatoon Health Region nor is there in the new Saskatchewan Health Authority. With limited literature on the subject, clinicians currently make the decision to allow/deny the request to record independently. The purpose of this study was to examine and compare patient and clinician perspectives concerning patients recording, in general, and recording their own procedures in the ED.MethodsSurveys were developed for patients and clinicians with respect to history and opinions about recording/being recorded. ED physicians and nurses, and patients>17 years old who entered the ED with a laceration requiring stitches were recruited to participate; 110 patients and 156 staff responded.ResultsThere was a significant difference between the proportion of patients (61.7% [66/107]) and clinicians (28.1% [41/146]) who believed that patients should be allowed to video record their procedure. There was also a significant difference between clinicians and patients with regard to audio recording, but not “selfies” (pictures). However, with no current policy, 47.8% (66/138) of clinicians said that they would allow videos if asked, with caveats about staff and patient privacy, prior consent, and procedure/patient care.ConclusionContrary to patients’ views, clinicians were not in favour of allowing audio or video recordings in the ED. Concerns around consent, staff and patient privacy, and legal issues warrant the development of a detailed policy if the decision is made in favour of recording.
