Further Development

Background: Application of chitin attracts much attention in the past decades as the second abundant polysaccharides in the world after cellulose. Chitin oligosaccharides (CTOS) and its deacetylated derivative chitosan oligosaccharides (COS) were shown great potentiality in agriculture by enhancing plant resistance to abiotic or biotic stresses, promoting plant growth and yield, improving fruits quality and storage, etc. Those applications have already served huge economic and social benefits for many years. However, the recognition mode and functional mechanism of CTOS and COS on plants have gradually revealed just in recent years. Objective: Recognition pattern and functional mechanism of CTOS and COS in plant together with application status of COS in agricultural production will be well described in this review. By which we wish to promote further development and application of CTOS and COS–related products in the field.

Background: Since the past two decades, the Lagos seaports have experienced vessel and storage yard cargo congestion, resulting in dwell times of about 30 days for containerised imports and high trade logistics costs.Objectives: The purpose of this study was to identify the critical factors that impact the operational efficiency of the Lagos seaports with a view to improving liner trade activities.Method: The study adopted an operational-based approach to understand the dynamics of the various interfaces of the port value chain. The research paradigm adopted for the study was therefore a combination of constructivism and post-positivism paradigms, which entailed the exploration and understanding of the various stakeholders in the port value chain. The epistemology of the research relied on the use of the exploratory sequential mixed method research technique (i.e. the qualitative approach followed by the quantitative approach) at the operational level of port operations.Results: The result of the research showed that significant challenges exist and that some of these challenges cut across all functions of port operations. Challenges are experienced in the areas of corruption, trade fraud, transport infrastructure deficits, the absence of a supply chain culture and shortcomings in the execution of the ‘contract of customs’. Additionally, these factors include the deficiencies in services and facilities provided by state agencies and government-appointed service providers and private sector companies such as truckers, inland container depots, Inland Container Depots (ICDs) and terminal operators.Conclusion: Specific recommendations are made to address the issues identified which, if implemented, could significantly address the current inefficiencies observed in the Lagos seaport’s operations.

Corporate social responsibility (CSR) is a tool used by companies to establish positive relations with their surroundings and gain a competitive edge. This also relates to centres providing services, such as seaports. In the past, these served as loading/off-loading and storage stations as well as ship terminals. At present, they have become versatile complexes administering land and infrastructure as well as playing host to numerous enterprises which offer a wide range of services to carriers and freight forwarders. Not only individual businesses but also entire port service hubs can, or even should, be socially responsible nowadays. The topic of this research is the social responsibility of sea ports. This article will discuss the social responsibility of the Port of Gdynia. The objective is to present socially responsible actions taken by Gdynia Port Authority SA and the largest port operators and to assess the progress made on the implementation of CSR there.

The development of oil&gas steel products in Baosteel in the past two decades is reviewed. After years of R&D works of steel products used in energy industry such as drilling, exploitation, collection, transportation, and storage of oil and gas, the alloy system and manufacturing processes of oil&gas steel products have been established in Baosteel. The oil&gas steel products of Baosteel consist of two major categories, i.e. the Oil Country Tubular Goods used in underground service, and the pipes used for pipeline construction on the ground. Currently, the product quality has been maintained stable, and the involved products have been extensively used in worldwide oil&gas exploration and transportation industry.

Awareness that our planet is a self-supporting biosphere with sunlight as its major source of energy for life has resulted in a long-term historical fascination with the workings of self-supporting ecological systems. However, the studies of such systems have never entered the canon of ecological or evolutionary tools and instead, have led a fringe existence connected to life support system engineering and space travel. We here introduce a framework for a renaissance in biospherics based on the study of matter-closed, energy-open ecosystems at a microbial level (microbial biospherics). Recent progress in genomics, robotics, and sensor technology makes the study of closed systems now much more tractable than in the past, and we argue that the time has come to emancipate the study of closed systems from this fringe context and bring them into a mainstream approach for studying ecosystem processes. By permitting highly replicated long-term studies, especially on predetermined and simplified systems, microbial biospheres offer the opportunity to test and develop strong hypotheses about ecosystem function and the ecological and evolutionary determinants of long-term system failure or persistence. Unlike many sciences, ecosystem ecology has never fully embraced a reductionist approach and has remained focused on the natural world in all its complexity. We argue that a reductionist approach to ecosystem ecology, using microbial biospheres, based on a combination of theory and the replicated study of much simpler self-enclosed microsystems could pay huge dividends.

Protein profiling using SELDI-TOF-MS has gained over the past few years an increasing interest in the field of biomarker discovery. The technology presents great potential if some parameters, such as sample handling, SELDI settings, and data analysis, are strictly controlled. Practical considerations to set up a robust and sensitive strategy for biomarker discovery are presented. This paper also reviews biological fluids generally available including a description of their peculiar properties and the preanalytical challenges inherent to sample collection and storage. Finally, some new insights for biomarker identification and validation challenges are provided.

Abstract Over the past few years considerable advances in sonar technology, spatial positioning capabilities and computer processing power have lead to significant improvements in mapping, imaging and technologies of seafloor exploration. Recently, modern multibeam echosounder systems (MBES) capable of recording backscatter data for the whole water column, not just for the seabed, have become available thus providing data allowing for visualization and analysis of objects other than the seabed such as single fish, fish schools or pollution. Unlike bathymetric sonars, which only capture the seafloor, multibeam systems produce very large amounts of data during surveys. Because of this, storing the data collected during hydrographic or scientific cruises becomes a crucial problem. In this context, the paper proposes a new approach for efficient reduction and storage of MBES records. The results of a sample implementation of the algorithm being tested on several different sets of MBES data are also discussed.

Over the past fifteen years, the United States has witnessed an extraordinary expansion in the banking and mining of DNA for law enforcement purposes. While the earliest state laws governing forensic DNA limited collection and retention of DNA samples to sexual offenders – on the theory that these persons were especially prone to recidivism and most likely to leave behind biological evidence – today forty-three states collect DNA from all felons, twenty-eight from juvenile offenders, and thirty-eight from those who commit certain categories of misdemeanors.A few states have expanded their databases beyond convicted criminals. Virginia, Louisiana, Texas, and California have authorized DNA retention from persons merely arrested for various offenses, although to date only Virginia has implemented such a program. At the federal level, an ill-considered statute that allows for the seizure and storage of DNA from anyone arrested and from non-U.S. citizens detained under federal authorities was recently signed into law.

SynopsisShellfish fishing, traditionally associated with crofting areas, has expanded greatly in Scotland generally, and particularly in the Inner Hebrides, during the past 30 years. Landings from Inner Hebrides waters in 1979 were valued at about £11 millions. Processing factories and storage installations have facilitated marketing.The seas around the Inner Hebrides provide a wide variety of habitats, from the fine mud necessary for Norway lobsters, through the sandy gravel on which scallops live, to the rocky sea bed inhabited by lobsters.The most valuable fisheries, those for Norway lobsters and scallops, are post-war developments. In both, the stocks appear to be in a healthy state. Landings in the traditional lobster fishery have declined recently and the stocks are giving some cause for concern. Periwinkles and queens make useful contributions to the economy. Pink shrimps and squat lobsters, though not sufficiently abundant to support a directed fishery, form a useful, occasional by-catch. Squids are caught sporadically, but their availability is very variable. The crab stocks could stand much greater exploitation.
