Distribution and pattern of moraines in Far NE Russia reveal former glacial extent

Here we present a series of six maps illustrating the distribution of end moraines in Far NE Russia. The maps are the first to systematically document the distribution of moraines across this region from the Verkhoyansk Mountains at the westernmost limit of our study area to the Chukchi Peninsula in the NE and to Kamchatka in the south, covering almost 4 million km2. Moraines were identified and mapped from analysis of satellite images and digital elevation model data. A total of 2173 moraines are identified, and we highlight some 197 more speculative features (perhaps moraines) that require further investigation. The distribution of moraines indicates that much of the region, now largely ice-free, was formerly occupied by glaciers centred upon the region’s uplands and that glacier outlets were typically < 200 km in length. The maps demonstrate the usefulness of remote sensing to derive an improved understanding of the glacial history of this vast and isolated region, and we present them to stimulate further work and act as a systematic framework for targeted geochronometric dating.

Children of the revolution: parents, children and the revolutionary struggle in late imperial Russia

While there has been a considerable growth in scholarly interest in Russian child- hood and youth, the presence of children in the revolutionary movement has largely been overlooked. Studies of female revolutionaries have acknowledged that family concerns often had an impact on women’s party careers, but few have explored fully the relationship between mothers and their children. Similarly, “general” historical works on the Russian revolution have rarely engaged with questions about the family lives of the predominantly male party members. This article will assess how becoming a parent affected the careers of both male and female revolutionaries, as well as the ways in which familial concerns and the presence of children had an impact on the movement itself. It will highlight that children could have both positive and negative effects on the operations of the underground, at times disrupting activities, but at others proving to be useful decoys and helpers. Children’s attitudes to their parents’ revolutionary careers will also be examined, highlighting that while some children wished they had less politically active parents, others enthusiastically helped the movement. Though expanding the scholarly gaze on the Russian underground to take in the presence of children does not change the grand narrative of the revolution, it enriches our understanding considerably and offers a new insight into the daily struggles of the revolutionary movement.

Treatment options for cutaneous warts in family practice

Natural regression should not be advocated as a treatment option for cutaneous warts, given the infectious nature of this condition. Although there are numerous treatments for this condition reported in the literature, many trials are uncontrolled and many regimens are unsuitable for general practice. Specific treatment is influenced by age of patients, number and sites of warts and availability of treatment. This paper reviews the international literature on treatment methods, with particular emphasis on effectiveness, patient acceptability and application in family practice.

A computerized audit of non-steroidal anti-inflammatory drug prescribing in general practice

The two group practices based in a city health centre decided to prescribe non-steroidal anti-inflammatory drugs in generic form from an agreed date. The practices' computer was used to identify the number of repeat prescriptions being issued for this group of drugs and to monitor the effectiveness of the changeover. Although both practices showed a marked increase in the level of generic prescribing there was considerable interpractice variation. Generic prescribing for one practice increased from 4% to 64% and for the other from 1% to 38% of repeat prescriptions issued for non-steroidal anti-inflammatory drugs over the study period. The reasons for this variation, the advantages of computerized audit and the problems associated with this self-imposed audit are discussed.

Essay - The role of ecological theory in microbial ecology

Microbial ecology is currently undergoing a revolution, with repercussions spreading throughout microbiology, ecology and ecosystem science. The rapid accumulation of molecular data is uncovering vast diversity, abundant uncultivated microbial groups and novel microbial functions. This accumulation of data requires the application of theory to provide organization, structure, mechanistic insight and, ultimately, predictive power that is of practical value, but the application of theory in microbial ecology is currently very limited. Here we argue that the full potential of the ongoing revolution will not be realized if research is not directed and driven by theory, and that the generality of established ecological theory must be tested using microbial systems.

Food-poisoning and commercial air travel

With the introduction of budget airlines and greater competitiveness amongst all airlines, air travel has now become an extremely popular form of travel, presenting its own unique set of risks from food poisoning. Foodborne illness associated with air travel is quite uncommon in the modern era. However, when it occurs, it may have serious implications for passengers and when crew are affected, has the potential to threaten safety. Quality, safe, in-flight catering relies on high standards of food preparation and storage; this applies at the airport kitchens (or at subcontractors' facilities), on the aircraft and in the transportation vehicles which carry the food from the ground source to the aircraft. This is especially challenging in certain countries. Several foodborne outbreaks have been recorded by the airline industry as a result of a number of different failures of these systems. These have provided an opportunity to learn from past mistakes and current practice has, therefore, reached such a standard so as to minimise risk of failures of this kind. This review examines: (i) the origin of food safety in modern commercial aviation; (ii) outbreaks which have occurred previously relating to aviation travel; (iii) the microbiological quality of food and water on board commercial aircraft; and (iv) how Hazard Analysis Critical Control Points may be employed to maintain food safety in aviation travel.
