Geological hydrogen storage, e.g. in depleted gas fields (DGF), can overcome imbalances between supply and demand in the renewable energy sector and facilitate the transition to a low carbon emissions society. A range of subsurface microorganisms utilise hydrogen, which may have important implications for hydrogen recovery, clogging and corrosion. We gathered temperature and salinity data for 75 DGF on the UK continental shelf and mapped their suitability for hydrogen storage in terms of the risk of adverse microbial effects, based on a novel collection of microbial growth constraints. Data on wind and solar operational capacities as well as offshore gas and condensate pipeline infrastructure were overlaid on the microbial risk categorization to optimize geographical centers of green hydrogen production, transport infrastructure and underground storage. We recommend storing hydrogen in 9 DGF that are at no microbial risk due to temperatures > 122 °C, or in the 35 low-risk DGF with temperatures > 90 °C. We recommend against utilising high-risk DGF with temperatures < 55 °C (9 DGF). Alignment with centers for renewable energy production and out-of-use pipelines suitable for repurposing to transport hydrogen suggests that no-risk and low-risk DGF in the Southern North Sea are the most suitable candidates for hydrogen storage. Our results advise site selection choices in geological hydrogen storage in the UK. Our methodology is applicable to any underground porous rock system globally.
This study explores the key determinants of intermediary performance in promoting corporate sustainability in small and medium‐sized enterprises in Africa. Despite being a critical link in the ...delivery of sustainability support services to small and medium‐sized enterprises, intermediaries have only received limited research attention. Research exploring intermediaries of corporate sustainability in small and medium‐sized enterprises have focused broadly on their roles but narrowly on performance. Those exploring intermediary performance have often focused on larger companies, sometimes, neglecting the specifics of small and medium‐sized enterprises, especially in African countries. Improving intermediary performance in promoting corporate sustainability requires an in‐depth understanding of the factors that determine their performance. As a qualitative study, interview responses from 32 experts working in National Cleaner Production Centres in four African countries were analysed using inductive thematic approach. The findings suggest that programme constraints, external profile, small and medium‐sized enterprises context, impact strategy, and service networks are the key determinants of intermediary performance in promoting corporate sustainability in small and medium‐sized enterprises. These determinants facilitate and inhibit intermediaries’ ability to promote corporate sustainability in small and medium‐sized enterprises. The implications concern the need for intermediaries and small and medium‐sized enterprises to manage these determinants in promoting corporate sustainability.

A survey was undertaken in 2016 of key informants in seven Sub-Saharan African countries about why there had been limited greening of industry in their countries. The results of this survey, combined ...with analysis of earlier studies drawn from a focused SSA literature review, find a multitude of relevant factors that act as drivers for, barriers to, and enablers for changing managerial attitudes and strategies on greening. The dominant cluster of drivers involves material costs, both the high costs of inputs and the related need for cost savings. The dominant cluster of barriers relates to the lack of information. Enablers, who play an important and essential role in lowering the barriers in firms to greening, figure weakly in the 11 reports considered. This possibly reflects the lack of effective government programmes that are essential for accelerating the greening of industry as called for in the United Nations Sustainable Development Goals.
The Soviet film industry, like any other institution, was made up of networks of people who knew each other, or who knew people who knew each other. In this article, Joan Neuberger examines some of ...those relationships using digital social network analysis. Applying digital network analysis to the connections between the directors and actors working in Soviet film during the period 1918-1953, she shows, first, some of the benefits of obscurity, and second, that changes in ethnic and regional integration during this period offer a different picture of centralisation than a study of political centralisation.
Les gobelets de Hama, ou gobelets syriens, qui sont très courants sur tous les sites de Syrie centrale, sont considérés comme des marqueurs chronologiques pour l’âge du Bronze ancien IV (ca 2500-2000 ...av. J.-C.). Dans cet article, nous présentons des données inédites provenant du site de Hama : il s’agit de plusieurs gobelets appartenant à la phase J. Cette étude est fondée à la fois sur une approche techno-morpho-stylistique et sur des observations microscopiques effectuées à la loupe binoculaire. L’objectif principal est de caractériser et de présenter les gobelets de Hama dans l’ordre chronologique des niveaux J8 à J1, afin de suivre leur évolution. L’ensemble des résultats montre l’existence d’au moins trois traditions céramiques distinctes, qui sont probablement le reflet de trois productions différentes. De plus, des études comparatives approfondies nous ont permis de définir certains types de gobelets comme marqueurs chronologiques pour les phases du Bronze ancien IV.
The ‘ Hama goblets’ or Syrian-type goblets, which were dominant in all the sites of Western Syria, are considered as being chronological markers of the Early Bronze Age IV period (ca 2500-2000 BC). This article provides unpublished data stemming from the Hama site : these are several goblets belonging to phase J. This study is based on a technological, morphological and stylistic analysis and on microscopic observations made with a stereo microscope. The primary aim was to describe and present the Hama goblets in the chronological order of levels J8 to J1 in order to trace their development. The results highlight the presence of at least three pottery traditions probably mirroring three distinct production centres. In addition, detailed comparative studies made it possible to define distinct goblet types as being chronological markers of the Early Bronze Age IV phases.
The United Nations Industrial Development Organization (UNIDO) and the United Nations Environment Programme (UNEP) jointly initiated the National Cleaner Production Centres (NCPCs) programme in 1995 ...with the funding of eight centres. The centres and the CP assessors trained by them do not deliver ready-made solutions, but rather they train and advise their clients on how to find the best solutions for specific problems. Two UNIDO evaluations of the programme confirm that the methodology for implementing the CP concept at the factory level is an effective tool for identification and prioritisation of technology changes that yield both environmental and financial benefits. However, the dissemination and application of the CP concept to small and medium size (SMEs) on the basis of its own financial merits does not occur easily; hence, there is a need to support the dissemination of the concept through promotional (awareness raising, training) activities, national policy formulation and access to financing.

Abstract
The main aims of this paper are to review briefly the various types of Sinopean amphorae of the Roman period, paying particular attention to newly-discovered and rare forms of these vessels, ...and to demonstrate their general evolution tendencies. Sinopean amphorae of the Roman period belong to two production traditions (local Hellenistic and pan-Roman), but are all made of the same fabric. The main problem when studying the Roman vessels is the lack of dated assemblages of the late 1st and 2nd centuries AD. As a result, there is a gap in the evidence between the evolution of the early Roman amphora and the vessels produced from the 3rd century onwards. Several new and rare varieties of Sinopean amphorae of this period, of both production traditions, are described in the article. They offer the opportunity to fill partly the gap between the early Roman Sinopean amphorae and the later vessels manufactured in Demirci, and to specify the typology and general evolution of the amphorae produced in Sinope.
