Carbon dating of basal peat deposits in Cumberland Bay and Stromness Bay and sediments from a lake in Stromness Bay, South Georgia indicates deglaciation at the very beginning of the Holocene before c. 9500 C-14 yr BP. This post-dates the deglaciation of one local lake which has been ice-free since at least 15 700 C-14 yr BP on account of its atypical geomorphological location. The latter indicate

The present study examined programmed death-1 ligand-1 (PD-L1) detected by immunohistochemical. labeling in 102 cases of human gastric carcinoma, 10 adenoma and 10 normal tissues. The relationship between PD-L1 immunolocalization and clinical pathological features, as well as the prognosis of gastric carcinoma, was explored. There was no PD-L1 detectable in normal gastric tissues and very weak imm

Allergic contact dermatitis to rubber is caused by residues of chemicals used in manufacturing a rubber product. Several different additives are used to achieve a final product of the desired characteristics. Accelerators such as thiurams, dithiocarbamates, and mercaptobenzothiazoles are often among the additives responsible for allergic reactions recognized by dermatologists. The chemistry of the

Methane production from llama and cow manures from the Bolivian high plateau (The "Altiplano") was studied using a parallel reactor set-up consisting of 10 lab-scale biogasifiers. The effects of pressure (495 and 760 mmHg), temperature (11 and 35 degrees C), hydraulic retention time (20 and 50 days), and manure content in the slurry (10%, 20% and 50%) were evaluated with respect to productivity an

The etiologic role of physical activity in endometrial cancer risk remains unclear given the few epidemiologic studies that have been conducted. To investigate this relation more fully, an analysis was,undertaken in the European prospective investigation into cancer and nutrition (EPIC). During an average 6.6 years of follow-up, 689 incident endometrial cancer cases were identified from an analyti

A sediment core from Lake Pichozero (61degrees46'; N, 37degrees25'; E 118 m a.s.l.) provides information on the environmental and climatic conditions in southeastern Russian Karelia during the Lateglacial and early Holocene (12800-9300 cal. BP). The chronology of the sequence is constrained by varve counting and AMS C-14 measurement of terrestrial plant macrofossils. Multiproxy analyses (magnetic

We propose a setup which allows us to couple the electron spin degree of freedom to the mechanical motions of a nanomechanical system not involving any of the ferromagnetic components. The proposed method employs the strain-induced spin-orbit interaction of electrons in narrow gap semiconductors. We have shown how this method can be used for detection and manipulation of the spin flow through a su

Vision is useful for the autonomous navigation of vehicles. In this paper the case of a vehicle equipped with multiple cameras with non-overlapping views is considered. The geometry and algebra of such a moving platform of cameras axe considered. In particular we formulate and solve structure and motion problems for a few novel cases. There are two interesting minimal cases; three points in two pl

During the summer of 1935, approximately 20,000 Swedish women mobilized in a peaceful action the Women's Unarmed Uprising Against War. The manifestation was a protest against rearmament and, in particular, against a militarization of everyday life that might result from a civil defense buildup. Thus, in a spirit of solidarity women were encouraged to refuse to use gas masks or evacuate into cellar

Background: Peroxisome proliferator-activated receptor (PPAR) alpha, beta delta and gamma are nuclear receptors activated by fatty acid metabolites. An anti-inflammatory role for these receptors in airway inflammation has been suggested. Methods: Nasal biopsies were obtained from 10 healthy volunteers and 10 patients with symptomatic allergic rhinitis. Nasal polyps were obtained from 22 patients,

Background: The role of inflammation as part of the explanation of socioeconomic differences in carotid atherosclerosis has not been specifically investigated. Methods and Results: The associations between socioeconomic position (SEP), C-reactive protein (CRP), and preclinical carotid atherosclerosis were investigated in a general population sample of 3921 middle-aged Swedish men and women. Common

Papillary secretion is a common symptom in the breast clinic with many different underlying causes like intraductal papilloma, mammary duct ectasia, infected cysts and abscesses, breast cancer/carcinoma in situ (CIS) and rarely pituitary adenoma. The association with cancer/CIS is one of the two main concerns of the patient and must always be ruled out. The second item is that spontaneous and ongo

Structural best management practices (BMPs) are now commonplace for stormwater management in new suburban developments; however, their installation in older central areas is limited. Here, the effect of disconnecting impervious areas from a combined sewer in favour of a new open stormwater system is investigated. The site, an inner city suburb of Malmo, Sweden, consists of council offices and apar

The polarisation pattern of skylight offers many arthropods a reference for visual compass orientation. The dung beetle Scarabaeus zambesianus starts foraging at around sunset. After locating a source of fresh droppings, it forms a ball of dung and rolls it off at high speed to escape competition at and around the dung pile. Using behavioural experiments in the field and in the laboratory, we show

This paper describes a bandpass amplifier topology for the GHz range using Q-enhancing that allows a systematic design approach to be used to control linearity, noise and power consumption. Frequency selectivity is achieved by a negative feedback network using a LC tank and a positive feedback networks using a resistor to achieve Q-enhancing. The feedback networks are fully passive in order to min

The structure of the N = Z nuclei Zn-60, Ga-62, Ge-64 and Kr-72 has been investigated at GASP. Total Routhian surface (TRS) calculations have been performed for the N = 36, 38 and 40 Kr isotones. In the case of Kr-72 the four quasi-particle g(9/2) alignment is observed to be significantly delayed in rotational frequency with respect to the heavier Kr isotopes. Such a delay contradicts the predicti
