Tapping the leakages : Methane losses, mitigation options and policy issues for Russian long distance gas transmission pipelines

The Russian natural gas industry is the world's largest producer and transporter of natural gas. This paper aims to characterize the methane emissions from Russian natural gas transmission operations, to explain projects to reduce these emissions, and to characterize the role of emissions reduction within the context of current GHG policy. It draws on the most recent independent measurements at al

A discussion covers a study made of greenhouse gas emissions in the transport of Russian natural gas to Germany and a comparing them with corresponding emissions from other fossil primary energy carriers. With the coming into force of the Kyoto protocol on 2/16/2005 climate protection strategies relying on a greater use of natural gas as a replacement for petroleum and brown and hard coal become mA discussion covers a study made of greenhouse gas emissions in the transport of Russian natural gas to Germany and a comparing them with corresponding emissions from other fossil primary energy carriers.

Models of general community assembly mechanisms simulating the spatial and temporal dynamics of benthic biodiversity

Benthic macroinvertebrates are part of a complex network of interactions. The spatial and temporal scales of the processes that form the basis for these interactions have traditionally restricted their empirical investigation. The first chapter of the manuscript attempts a review of the modelling tools that have been employed for the study of the marine benthos.The implementation of a mechanistic

Elucidation of Hydrogen Bonding Patterns in Ligand-Free, Lactose- and Glycerol-Bound Galectin-3C by Neutron Crystallography to Guide Drug Design

The medically important drug target galectin-3 binds galactose-containing moieties on glycoproteins through an intricate pattern of hydrogen bonds to a largely polar surface-exposed binding site. All successful inhibitors of galectin-3 to date have been based on mono- or disaccharide cores closely resembling natural ligands. A detailed understanding of the H-bonding networks in these natural liganThe medically important drug target galectin-3 binds galactose-containing moieties on glycoproteins through an intricate pattern of hydrogen bonds to a largely polar surface-exposed binding site.

On the Asymptotics of Solving the LWE Problem Using Coded-BKW with Sieving

The Learning with Errors problem (LWE) has become a central topic in recent cryptographic research. In this paper, we present a new solving algorithm combining important ideas from previous work on improving the Blum-Kalai-Wasserman (BKW) algorithm and ideas from sieving in lattices. The new algorithm is analyzed and demonstrates an improved asymptotic performance. For the Regev parameters $q=n^2$

Spontaneous remission of "aleukemic" skin chloroma

We report a unique case of "aleukemic" skin chloroma located at the place of previous head injury. Chloroma presented as a local livid papulous skin infiltration (5x3cm), whilst physical examination and patient's complete blood counts were normal. Chloroma spontaneously disappeared. One month later, a diagnosis of acute myeloid leukemia was made. We discussed different pathogenetic mechanisms of t
