There is growing demand for cost effective and reliable floating production systems to maximize marginal and new deepwater fields worldwide. Floating Production Storage and Offloading (FPSO) vessels are considered to be the most economical and viable options to meet this demand. Yet, FPSO projects are prone to significant cost and schedule growth. On average, FPSOs have been reported to experience a 20% cost growth and are delayed by six months. Overruns and delays represent uncertainties for owners, contractors and financial institutions. In-depth interviews with twenty-three practitioners about their experiences with FPSO projects revealed that rework arising from design and construction errors were major contributors to cost and schedule growth. Key latent conditions contributing to rework are classified according to people, organization and project. Using retrospective sensemaking an examination of the determinant histories in a new build and conversion FPSO that experienced rework was undertaken. The sharing of experience(s) is deemed pivotal for reducing rework in future projects, particularly through the use of communities of practice that are able to stimulate situated learning to take place. A reduction in rework will not only reduce cost and schedule growth, improve operational performance and augment safety.

Climate change, food security, and the protection of the planet’s resources require the adoption of sustainable production models. Achieving sustainable development in the agri-food sector enables the creation of new opportunities for operators, guiding farmers towards more environmentally friendly practices and offering cost-effective results. Organic farming paradigms are promoted by the transformation of some harmful practices of conventional agriculture, such as the wide use of chemical products of synthesis, the deep workings that favor the erosive processes, the excessive use of nitrogenous fertilizers. There are still gaps in the knowledge of the real performance of some products that strongly support the local economic system of Sicily (Italy). The research aims to highlight the differences in environmental impact caused by the cultivation of organic early potatoes compared to the conventional regime and the same per kg of product obtained. To this end, the widely used methodology for comparing the environmental impacts of agricultural production systems is the Life Cycle Assessment, which allows us to highlight the phases in which environmental criticalities are most concentrated. An interesting agroecological picture of knowledge emerges, since organic farming is by definition an ecological model that supports the principles of the Green Deal, it often requires interventions to improve the yields obtained in order to achieve a positive result both in terms of cultivated surface and kg of product obtained.

The options for conventional graduate careers have become more limited in the last 20 years. This has stimulated an increase in university programmes and modules designed to encourage students to start their own businesses. The recent global Covid-19 pandemic is likely to make the job market even more difficult for those graduating from universities in the next few years. A career as an entrepreneur is a realistic alternative to employment in the ‘gig’ economy for many young graduates. University-based incubators can provide a sheltered learning environment for those wishing to develop business ideas without incurring a large financial burden. In this paper, the authors draw on a range of literature (business incubation, entrepreneurial learning, human capital and communities of practice) to develop a model of a university-based incubator that will support young people in their transition to becoming real entrepreneurs.

AbstractIntra-plant transport systems within their operation directly impact on the performance of production systems. For their effective operation, it is, therefore, necessary to realize evaluation of operational performance and effectivity. For the realization of this type of evaluation, in addition to a wide range of sensors that can be difficult for installation and operation, we can also use indirect methods that are equally able to provide reliable operational characteristics. Indirect analytical methods are presented above all by the approach which is based on the use of simulation methods. The method of computer simulation provides a wide range of options for the evaluation of efficiency and performance. The paper describes the use of a simulation model created in the program Tecnomatix Plant Simulation for analyzing the supply of production workplaces within the MilkRun system.

Increasing numbers of subsea structures related to wells and pipelines are being placed on the seabed as part of typical subsea or tie-back developments. Given the proliferation of these structures and the marginal cost of offshore developments, controlling installation and fabrication costs for subsea structures can be key to project viability. Skirted mudmats are often the most cost-effective foundation type, and particular additional design focuses on optimising their cost by minimising foundation weight and installation time. Subsea foundations must be designed to withstand all applied loads during their design life (e.g. during set-down, tie-in, hydrotest, operation etc.) with suitable reliability. Using skirts, peripheral or internal, to improve the sliding resistance is an efficient solution provided the self-weight of the subsea structure on set-down is sufficiently large to ensure installation of the skirts (even for the strongest likely seabed conditions), but can lead to significant cost increases if additional ballast is required to ensure this. The paper examines how foundation skirt geometries can be optimised in order to provide sufficient foundation in-place capacity whilst minimising the amount of self-weight required for their installation. Parametric studies are presented that show how the sliding capacity of individual skirts is affected by the weight of the structure, and also the spacing and position within the foundation plan.

Background:  To explore the influences of pharmaceutical companies on prescription practices and to find out types of incentives of pharmaceutical companies on medical doctors in private and public hospitals in Islamabad, the capital city of Pakistan  Methods: A qualitative exploratory study was conducted in 06 months May-Oct: 2017 in Islamabad (Capital City of Pakistan). Data were collected from doctors and pharmaceuticals representatives through snowballing sampling techniques through open ended questionnaire in which In-depth interviews were taken. In depth interviews were recorded, transcribed and coded. Qualitative sub-component was included to triangulate the data, sub themes and themes were generated. Results: Respondent’s prescription is a basically document in which we suggest minimum effective medication therapy to the patient, that is also cost effective and give maximum treatment to the patient.  Few of the respondents are also agreeing on the point that most of the times patient itself influences to prescribe the particular product. Patient itself influences to prescribe the particular product that is redundant in its treatment regimen. Other respondents stated that prescription is varying from patient to patient and our priority is to give the medicine to the patient which shows good efficacy. Conclusion: Most doctors were maintaining protocol of prescription and using brand name of medicine. Pharmacists were visiting them on regular basis conditionally.

The Cost

Objective: Operating rooms (OR) generate a large portion of hospital revenue and waste. Consequently, improving efficiency and reducing waste is a high priority. Our objective was to quantify waste associated with opened but unused instruments from trays and to compare this with the cost of individually wrapping instruments.Methods: Data was collected from June to November of 2013 in a 550-bed hospital in the United States. We recorded the instrument usage of two commonly-used trays for ten cases each. The time to decontaminate and reassemble instrument trays and peel packs was measured, and the cost to reprocess one instrument was calculated.Results: Average utilization was 14% for the Plastic Soft Tissue Tray and 29% for the Major Laparotomy Tray. Of 98 instruments in the Plastics tray (n = 10), 0% was used in all cases observed and 59% were used in no observed cases. Of 110 instruments in the Major Tray (n = 10), 0% was used in all cases observed and 25% were used in no observed cases. Average cost to reprocess one instrument was $0.34-$0.47 in a tray and $0.81-$0.84 in a peel pack, or individually-wrapped instrument.Conclusions: We estimate that the cost of peel packing an instrument is roughly two times the cost of tray packing. Therefore, it becomes more cost effective from a processing standpoint to package an instrument in a peel pack when there is less than a 42%-56% probability of use depending on instrument type. This study demonstrates an opportunity for reorganization of instrument delivery that could result in a significant cost-savings and waste reduction.

Design And Construction

The development of urban infrastructure projects like metro rail projects in the major cities in India is one of the challenging tasks due to several site construction and operating constraints. These rapid transit systems (RTS) are conceived to minimise traffic congestion by providing commuters with fast and efficient transportation alternatives. One such project is the Phase-II of the ongoing Bangalore Underground Metrorail Project. The design and construction of the metro rail project require sound engineering judgment and field experience on envisaged strata conditions along the proposed route alignment. The important factors that govern the excavation cycle depend on Rock mass material properties, efficient blast design and construction performance. All these considerations needs to be evaluated for achieving safe, cost-effective excavation design layouts. Proper blast design and safe blasting operations play a key role in achieving good fragmentation, minimising over break and equipment downtime. Site-specific innovative methods on controlled blasting techniques are being experimented with and demonstrated to minimise the ground vibrations. The major challenge lies with the design of efficient and smooth wall blasting techniques to safeguard the old heritage buildings and other subsurface structures and utilities.

Financial institutions are currently needed by all people because financial institutions are considered to be quicker in providing business capital loans. Previously, conventional banks were the only financial institutions operating in the financial sector or loans to the community before Islamic financial institutions, now with the development of financial institutions sharia society mostly prefers sharia finance rather than conventional, plus BMT which operates in the middle to lower class, this is what causes many people to take Islamic financial institutions because they prioritize family systems, so this study focuses on: 1). How is the application of murabahah financing at BMT As-Salam to brick businesses in the Ngreco Kandat Kediri village, 2). What is the role of murabahah financing at BMT As-Salam towards brick business in the Ngreco Kandat Kediri village, 3). How did the brick business increase in the Kandat Kediri Ngreco village after obtaining murabahah financing at BMT As-Salam. Research on the role of murabahah financing in brick business uses a descriptive qualitative approach with a type of case study research that refers to the interpretive postpositivistic thinking paradigm. The technique of collecting data is in-depth interviews, observation and documentation. The results of this study indicate that the application of murabahah financing at BMT As-Salam is very different where loans for business capital of bricks that should use mudharabah or musyarakah at BMT These salads use murabaha. Besides that the role of BMT As-Salam is very influential on brick business and before BMT As-Salam arrived, brick entrepreneurs still had difficulty finding capital to improve their business but after taking murabahah financing at BMT As-Salam, their efforts experienced an increase and prosperity life.
