A hypothesis on the mechanism of "salt-scaling" of porous building materials based on theories for frost heaving in soils and observations made by Powers and Helmuth /1953/ is described. Though the text mainly deals with cement based materials, the mechanism described should be valid for any brittle, porous material. A simplified calculation of possible scalings shows that the hypothesis predicts

Objective: To explore the use and interpretation of self reported on/off diary data for assessment of daily motor fluctuations in Parkinson’s disease. Methods: 26 consecutive non-demented patients with fluctuating Parkinson’s disease received standardised training on how to fill out the four category CAPSIT-PD on/off diary, followed by four hours of clinical observation and four weeks of daytime

Purpose: Soft tissue sarcomas (STS) account for less than 1% of all malignancies and constitute a heterogeneous tumor entity in which malignant fibrous histiocytomas (MFH) represent one-third and are characterized by a lack of type-specific differentiation. A defective mismatch repair (MMR) system cause the familial cancer syndrome hereditary non-polyposis colorectal cancer (HNPCC), and since occa

1:2 Cocrystals of piperazine (PPN) with o- and p-nitrophenol (oNPH and pNPH) were obtained from aqueous solution. The co-crystal structure of PPN, 2pNPH, and 2H(2)O is triclinic space group P (1) over bar: a = 6.401(1) Angstrom, b = 6.7515(1) Angstrom, c = 11.219(1) Angstrom, alpha = 100.37(1)degrees, beta = 97.10(1)degrees, gamma = 99.99(1)degrees,V= 465.5(1) Angstrom(3), Z = 2. Refinement led to

A Swedish patient with typical symptoms of the Sanfilippo Syndrome (Mucopolysaccharidosis III) is described. The early onset of the disease, the presence of hepatomegaly, early dementia and the absence of umbilical bernia are consistent with the subgroup Sanfilippo A. Enzyme studies indicate the diagnosis Sanfilippo C, and thus the patient represents a more severe form of this subgroup than any of

The article discusses the construction of 3G infrastructure under four themes from planning and sociology of law perspectives. This includes the design of the initial license procedure, the 3G-developments physical aspects in a different actors driving forces point of view and the practical sides of sustainability issues at both regional and local level. Public concern over electromagnetic radiati

BACKGROUND AND PURPOSE: Serotonin released from platelets has been suggested as one substance causing the vasospasm following subarachnoid hemorrhage. We studied whether such serotonin is able to constrict pial vessels. METHODS: We studied the uptake of serotonin in pial perivascular nerves by immunohistochemistry. We measured the contractile response in rat basilar artery after in vitro incubatio

ESA's Gaia mission will provide accurate astrometric, photometric andspectroscopic data for millions of stars in the Galaxy and beyond. Wediscuss the prospects of using this vast amount of astrophysicalinformation for understanding star formation histories in the Galaxy andits immediate neighbors within the Local Group.

The purpose of this dissertation is to study the concept of autism from a socio-legal perspective and to analyze the actual use of law in an area where knowledge rivalry is present, as in the case of autism. The ambition is to illustrate how law reacts to, and deals with, rivalry fields of knowledge within the system of decision-making. During the last decades, research on autism has been intense

Embedded systems are becoming increasingly networked and aredeployed in application areas that require close interaction withtheir physical environment. Examples include distributed mobileagents and wireless sensor/actuator networks. The complexity ofthese applications make co-simulation a necessary tool during systemdevelopment. This paper presents a simulation environment thatfacilitates simulat

RATIONALE AND OBJECTIVES: The movements of the soft palate and the larynx are crucial in pharyngeal manometry because of the potential risk of manometry sensor dislocation. METHODS: Twenty dysphagic patients and 20 nondysphagic volunteers were examined with simultaneous videoradiography and intraluminal pharyngeal solid-state manometry. The movements of the manometric sensors were analyzed from la
