Several recent studies have found markedly increased rates of schizophrenia among West Indian immigrants to the UK. Almost exclusively, authors have sought psychosocial explanations for these findings. This paper hypothesises that environmental causes, notably obstetric complications and perinatal infections, provide more plausible aetiological models, especially for the raised rates of schizop...

The present experiment examined the effects of input/output modality pairings on dual-task performance using the psychological refractory period (PRP) procedure. Four groups of participants performed two tasks composed of the same sets of inputs (visual and auditory) and the same sets of outputs (manual and vocal), but with different input/output modality pairings. Whereas modality pairings had...

AIM To investigate the incidence of colorectal cancer in the Split-Dalmatia County in the 1981-1998 period, and compare it with the incidence in the Republic of Croatia. METHODS The data were obtained using case records and registries of all hospitals and Public Health Institute in the County and the Croatian Cancer Registry. Age-standardized incidence per 100,000 was calculated from the numb...

Pressurized hot water extraction (PHWE) has become a popular green extraction method for different classes of compounds present in numerous kinds of matrices such as environmental, food and botanical samples. PHWE is also used in sample preparation to extract organic contaminants from foodstuff for food safety analysis and soils/sediments for environmental monitoring purposes. The main paramete...

During the period from 1987 to 1998, 13 cases of human sporotrichosis were recorded at the Research Center Evandro Chagas Hospital (CPqHEC) in Rio de Janeiro. Two of these patients related scratch by a sick cat. During the subsequent period from July 1998 to July 2000, 66 human, 117 cats and 7 dogs with sporotrichosis were diagnosed at the CPqHEC. Fifty-two humans (78.8%) reported contact with ...

important producer countries of wood and paper products are identified by this study. identification of these countries is important for trade of wood and paper products. ranking of different regions of the world was done using mean values of the production based on fao 10 years reports from 1998 to 2007. results showed that the production value for the major part of the products was almost con...

To get some intuition, we begin with the group of real numbers R under addition. A trivial upper bound for the size of a sum set is |A + A| ≤ |A| 2+|A| 2 (equality is obtained when every pair of elements of A have a distinct sum). If we build A by taking elements of R at random, then we expect |A+A| to be very close to this upper bound, since the probability of a1+a2 = a3+a4 is very small (wher...

The Clifford tori in S constitue a one-parameter family of flat, two-dimensional, constant mean curvature (CMC) submanifolds. This paper demonstrates that new, topologically non-trivial CMC surfaces resembling a pair of neighbouring Clifford tori connected at a sub-lattice consisting of at least two points by small catenoidal bridges can be constructed by perturbative PDE methods. That is, one ...
