Thermochemistry of metallic alkyls : Part 7. - The heat of formation of mercury diphenyl, and of mercury phenyl chloride
The heat of reaction of mercury diphenyl with hydrogen chloride in benzene solvent has been measured at 25°C. The heat of reaction of mercury diphenyl with mercuric chloride in methanol solvent has also been measured. From these heats of reaction, the heat of formation of mercury diphenyl has been derived: ΔHf° (Hgφ2, cryst.) = 65.4 ± 2 kcal/mole. Previous data on the heats of reaction of mercury
Relation between occupational exposure to organic solvents and chromosome aberrations in non‐Hodgkin's lymphoma
Chromosome analysis of lymphoma cells was performed in 54 untreated patients with non‐Hodgkin's lymphoma (NHL). 10 patients had a history of daily occupational handling of organic solvents for at least 1 year (exposed group) and 44 patients had never (or only for shorter periods) worked with solvents (unexposed group). There were no differences between exposed and unexposed patients regarding age,
Cancer incidence after cholecystectomy - A cohort study with 30 years follow-up
Cholecystectomy has been connected with an increase in colorectal, breast and reproductive system cancers. On 472 patients, 398 women and 74 men, cholecystectomized during the years 1951 to 1955, cancer incidence was investigated. Our results show an elevated risk of breast cancer in the female group (P = 0.016), but no significant increased risk in colorectal or gynaecologic cancer. The risk for
No abnormal C‐band polymorphism in lung cancer patients
The C‐band heterochromatin polymorphism of chromosomes 1, 9, and 16 was studied in lymphocytes from 52 lung cancer patients and 183 control persons. No significant differences between the controls and patients were found regarding heterochromatin block size, the frequency of partial and total inversions, or the symmetry/asymmetry pattern.

Early oral contraceptive use and breast cancer among premenopausal women : Final report from a study in Southern Sweden
In southern Sweden during the 1960s, women began to use oral contraceptives (OCs) extensively at a young age. This case-control study investigates the relationship between the use of OCs and breast cancer development in women in southern Sweden diagnosed in the early 1980s. The risk for breast cancer after OC use among premenopausal women was modeled, after adjustment was made for age, age at mena
Institutional Risk
The concept of institutional risk is defined as the risk that the regulator will not meet its organizational and policy objectives. The counterpart of institutional risk is societal risk, that is, the risks in society that regulators are entrusted to manage. In recent decades risk management has for various reasons become an attractive solution for societal regulation on all levels. Despite this s
Properties of electrolyte-filled glass microelectrodes : a model analysis
A novel dynamic mathematical microelectrode model (a model of solvent and solute kinetics in electrolyte-filled microelectrodes) was deduced from experimental observations made on standard (single-barrelled, 3.0 M KCl-filled, approximately 10 M[ohm]) electrodes using (a) electrodiffusion, electro-osmosis, and continuity equations that were placed into the constraints of electrode geometry, and (b)
Analysis of leak current properties in the lobster stretch receptor neurone
Experiments were performed to characterize the so-called leak current of the slowly adapting stretch receptor neurone of the European lobster with respect to its ionic basis, its kinetics and its pharmacology. Estimates of the leak current were obtained by subtraction of a Na-K pump current and of an unspecific impalement current from a non-dynamic ('instantaneous') current, recorded in a voltage
Properties of electrolyte-filled glass microelectrodes : an experimental study
The electrochemical and electrical properties of geometrically defined electrolyte-filled microelectrodes were studied at various transelectrode current passages, using radiotracer (38Cl and 42K) and electrical techniques. Geometrically, the electrodes were defined by their tip properties that, for standard (single-barrelled, 3.0 M KCl-filled, approximately 10 M[ohm]) electrodes implied a tip open

Islamic Modernities in Southeast Asia. Exploring Indonesian Popular and Visual Culture, by Leonie Schmidt
In Islamic Modernities in Southeast Asia, Leonie Schmidt provides a thorough analysis of contemporary Islamic-themed popular and visual cultures, mainly in Indonesia. This book is an essential read for those who wish to understand multiple modernities unfolding in post-1998 Indonesia (the Reformasi era). By using the term Islamic, she refers to any ‘cultural practices that are considered bernafask
IoT protection through device to cloud synchronization
This paper addresses the problem of protecting distributed IoT units from network based attacks while still having a high level of availability. In particular we suggest a novel method where the IoT device execution state is modeled with a suitable high level application model and where the execution state of the application of the IoT device is 'mirrored' in a cloud executed machine. This machine
Providing User Security Guarantees in Public Infrastructure Clouds
The infrastructure cloud (IaaS) service model offers improved resource flexibility and availability, where tenants-insulated from the minutiae of hardware maintenance-rent computing resources to deploy and operate complex systems. Large-scale services running on IaaS platforms demonstrate the viability of this model; nevertheless, many organizations operating on sensitive data avoid migrating oper
On improving resistance to Denial of Service and key provisioning scalability of the DTLS handshake
DTLS is a transport layer security protocol designed to provide secure communication over unreliable datagram protocols. Before starting to communicate, a DTLS client and server perform a specific handshake in order to establish a secure session and agree on a common security context. However, the DTLS handshake is affected by two relevant issues. First, the DTLS server is vulnerable to a specific
Bootstrapping trust in software defined networks
Software-Defined Networking (SDN) is a novel architectural model for cloud network infrastructure, improving resource utilization, scalability and administration. SDN deployments increasingly rely on virtual switches executing on commodity operating systems with large code bases, which are prime targets for adversaries attacking the network infrastructure. We describe and implement TruSDN, a frame
Perioperative alcohol cessation intervention for postoperative complications
Background: Risky consumption of alcohol is a global problem. More than 3.3 million deaths annually are associated with risky use of alcohol, and global alcohol consumption continues to increase. People who have high alcohol consumption often require planned and emergency surgical procedures. Risky drinking is associated with increased postoperative complications such as infections, cardiopulmonar
