Abstract:

Only few descriptions of intraoperative carcinoid syndrome (ioCS) have been reported. The primary objective of this study was to describe ioCS. A second aim was to identify risk factors of ioCS. We retrospectively analysed patients operated for small-bowel neuroendocrine tumour in our institution between 2007 and 2015, and receiving our preventive local regimen of octreotide continuous administration. ioCS was defined as highly probable in case of rapid (<5 min) arterial blood pressure changes ≥40%, not explained by surgical/anaesthetic management and regressive ≥20% after octreotide bolus injection. Probable cases were ioCS which did not meet all criteria of highly-probable ioCS. Suspected ioCS were detected on the anaesthesia record by an injection of octreotide due to a manifestation which did not meet the criteria for highly-probable or probable ioCS. A total of 81 patients (liver metastases: 59, prior carcinoid syndrome: 49, carcinoid heart disease: 7) were included; 139 ioCS occurred in 45 patients: 45 highly probable, 67 probable and 27 suspected. ioCs was hypertensive (91%) and/or hypotensive (29%). There was no factor, including the use of vasopressors, significantly associated with the occurrence of an ioCS. All surgeries were completed and one patient died from cardiac failure 4 days after surgery. After preoperative octreotide continuous infusion, ioCS were mainly hypertensive. No ioCS risk factors, including vasopressor use, were identified. No intraoperative carcinoid crisis occurred, suggesting the clinical relevance of a standardized octreotide prophylaxis protocol.

Abstract:

In this study, modification of iron-oxide-coated sand (IOCS) with three quaternary ammonium compounds (QACs) was tested as a means to improve the removal of aqueous natural organic matter (NOM) by IOCS. The assessment was conducted in batch, isotherm setup with changes in types and concentrations of QACs, modification pH, additions of H2O2 during modification, and adsorption pH. IOCS modification with long chain QACs, including hexadecyltrimethylammonium bromide (HDTMA) and hexadecylbenzyldimethylammonium chloride (HDBDMA) significantly increased the adsorption of NOM, while coating IOCS with short chain QAC, tetrapropylammonium chloride (TPA) had no positive effect. The enhancement increased with increasing pH and increasing QAC concentration used during modification. Co-additions of long chain QACs with H2O2 during modification could further improve NOM adsorption. Modification of IOCS with 10.0 mM HDTMA at pH 9.9 with the 0.2% H2O2 addition doubled NOM adsorption capacity on IOCS at pH 9.1. The results presented here suggest that the modification of IOCS using long chain QACs can enhance NOM removal by IOCS during drinking water treatment.

Abstract:

The influence of salinity on the single and binary sorption of Ni and Zn onto iron oxide- and manganese oxide-coated sand (IOCS and MOCS) was investigated at pH = 5. The single sorption experimental data were fitted to Freundlich, Langmuir, Dubinin–Radushkevich, and Sips models, and a nonlinear sorption isotherm was observed (NF = 0.309–0.567). The higher Brunauer–Emmett–Teller (BET) surface area (ABET) and cation exchange capacity (CEC) of MOCS contributed to the higher maximum sorption capacities (qmL) of Ni and Zn than that of IOCS. The Ni sorption capacities in the single sorption were higher than that in the binary sorption, while the Zn sorption capacities in the single sorption were less than that in the binary sorption. The single and binary sorptions onto both IOCS and MOCS were affected by the salinity, as indicated by the decrease in sorption capacities. Satisfactory predictions were shown by the binary sorption model fitting including P-factor, ideal adsorbed solution theory (IAST)–Freundlich, IAST–Langmuir, and IAST–Sips; among these, the P-factor model showed the best fitting results in predicting the influence of salinity of Ni and Zn in the binary sorption system onto IOCS and MOCS. IOCS and MOCS offer a sustainable reactive media in a permeable reactive barrier (PRB) for removing Ni and Zn in the presence of salinity.

Abstract:

For the removal of iron from groundwater, aeration followed with rapid (sand) filtration is frequently applied. Iron removal in this process is achieved through oxidation of Fe2 + in aqueous solution followed by floc formation as well as adsorption of Fe2 + onto the filter media. The rate of oxidation of the adsorbed Fe2 + on the filter media plays an important role in this removal process. This study focuses on investigating the effect of pH on the rate of oxidation of adsorbed Fe2 + . Fe2 + has been adsorbed, under anoxic conditions, on iron oxide coated sand (IOCS) in a short filter column and subsequently oxidized by feeding the column with aerated water. Ferrous ions adsorbed at pH 5, 6, 7 and 8 demonstrated consumption of oxygen, when aerated water was fed into the column. The oxygen uptake at pH 7 and 8 was faster than at pH 5 and 6. However the difference was less pronounced than expected. The difference is attributed to the pH buffering effect of the IOCS. At feedwater pH 5, 6 and 7 the pH in the effluent was higher than in the influent, while a pH drop should occur because of oxidation of adsorbed Fe2 + . At pH 8, the pH dropped. These phenomena are attributed to the presence of calcium and /or ferrous carbonate in IOCS.

Abstract:

Abstract International Oil Companies (IOC’s) had been playing a major role in oil industry at the beginning of 20th century. They had many volatility during last century and faced with many obstacles which forced them to change their business models and improve their outcome to satisfy their shareholders. One of the most important challenges was oil nationalization in oil producer countries which were happened by establishment of NOCs. Later green energy issue which came from CO2 emission problem happened and recently, oil and gas price diminish challenges, involve all IOCs with the most important challenge in last century after all. Among all those events, one of the most important key values which have been observed by IPIECA, API and IOGP associations every year is Sustainability. The objectives of the research are study all issues and indicators of sustainability in IOCs. Each indicator has faced with different strategy via IOCs in different market situation. The importance of this key value cause that it is observed by some important association like IPIECA, API and IOGP each year. As the scarcity of related references for business model in oil and gas industry, literature review of some resources and annual sustainability report followed by a questionnaire as a survey are also selected methods for recent major challenges to achieve required result.

Abstract:

Purpose This study aims to identify factors influencing corporate social responsibility reporting (CSRR) practices of international oil companies (IOCs) in Nigeria. It aims at distinguishing CSRR levels by examining both the quantity and quality of reporting. Design/methodology/approach The paper analyses annual reports through content analysis. CSRR extent and type are measured by the number of sentences. CSRR are further classified into three subcategories according to whether they are negative, neutral or positive reports and then their proportions compared through descriptive analysis. Findings For the extent and quality of CSRR, community was the most reported category. The majority of the total CSRR in the IOCs is positive with little evidence of negative news. None of the IOCs in the sample reported on the environment in their annual reports. Research limitations/implications The measurement of CSRR focuses only on annual reports, without consideration of other reporting media such as standalone reports and corporate websites. CSRR are assumed to be voluntary for the companies and they may choose not to report any information in annual reports, as there are no regulations or reporting guidelines in Nigeria to be followed. Practical implications The results reveal the absence of environmental reporting in the CSRR of IOCs in Nigeria suggests that they are less concerned with meeting local demands for accountability. The study recommends the need for regulatory intervention on the part of the Nigerian Government. Social implications The findings of study indicate that predominant existence of positive CSRR news among all the IOCs suggests there’s an attempt to encourage stakeholders and the public to believe that they are conscious of society and the environment. Originality/value The main contribution of this study lies in identifying the factors that have led to diversity and uniqueness in CSRR in IOCs. As such, this study seeks to contribute to the development of understanding multiple factors that could give rise to changing patterns of CSRR.

Abstract:

Abstract Objectives To share our experience with digital slide telepathology for intraoperative frozen section consultations (IOCs) and to describe its evolution over time by reporting performance metrics and addressing organizational and economic aspects. Methods Since 2013, a technician has been alone at the surgical site. At the other site, the pathologist opens the digital slide from a local server via the intranet. Three periods were compared: a 6-month period of conventional IOC (period 1), a 24-month period of telepathology at 6 months after implementation (period 2), and a 12-month period of telepathology at 3.5 years after implementation (period 3). Results In total, 87 conventional IOCs and 464 and 313 IOCs on digital slides were performed respectively during periods 1, 2, and 3; mean turnaround time was 27, 36, and 38 minutes, respectively, and there were a mean number of 1.1, 1.1, and 1.3 slides, respectively, per IOC. Diagnostic accuracy was achieved in 95.4%, 92.7%, and 93.9%, respectively, of IOCs (not significant). The additional cost is in the same range as the cost of urgent transport by courier. Conclusions Developing IOC with digital slides is a challenge but is necessary to optimize medical time in the current context of pathologist shortage and budget restrictions.

Abstract:

Object Three-column resection osteotomies (3COs) are commonly performed for sagittal deformity but have high rates of reported complications. Authors of this study aimed to examine the incidence of and intercenter variability in major intraoperative complications (IOCs), major postoperative complications (POCs) up to 6 weeks postsurgery, and overall complications (that is, both IOCs and POCs). They also aimed to investigate the incidence of and intercenter variability in blood loss during 3CO procedures. Methods The incidence of IOCs, POCs, and overall complications associated with 3COs were retrospectively determined for the study population and for each of 8 participating surgical centers. The incidence of major blood loss (MBL) over 4 L and the percentage of total blood volume lost were also determined for the study population and each surgical center. Complication rates and blood loss were compared between patients with one and those with two osteotomies, as well as between patients with one thoracic osteotomy (ThO) and those with one lumbar or sacral osteotomy (LSO). Risk factors for developing complications were determined. Results Retrospective review of prospectively acquired data for 423 consecutive patients who had undergone 3CO at 8 surgical centers was performed. The incidence of major IOCs, POCs, and overall complications was 7%, 39%, and 42%, respectively, for the study population overall. The most common IOC was spinal cord deficit (2.6%) and the most common POC was unplanned return to the operating room (19.4%). Patients with two osteotomies had more POCs (56% vs 38%, p = 0.04) than the patients with one osteotomy. Those with ThO had more IOCs (16% vs 6%, p = 0.03), POCs (58% vs 34%, p < 0.01), and overall complications (67% vs 37%, p < 0.01) than the patients with LSO. There was significant variation in the incidence of IOCs, POCs, and overall complications among the 8 sites (p < 0.01). The incidence of MBL was 24% for the study population, which varied significantly between sites (p < 0.01). Patients with MBL had a higher risk of IOCs, POCs, and overall complications (OR 2.15, 1.76, and 2.01, respectively). The average percentage of total blood volume lost was 55% for the study population, which also varied among sites (p < 0.01). Conclusions Given the complexity of 3COs for spinal deformity, it is important for spine surgeons to understand the risk factors and complication rates associated with these procedures. In this study, the overall incidence of major complications following 3CO procedures was 42%. Risks for developing complications included an older age (> 60 years), two osteotomies, ThO, and MBL.

Abstract:

The oil and gas (O&G) industry has long been at the forefront of integrated operations centres (IOCs). A remote control room is often the starting point for an IOC. The control room is responsible for monitoring operations, reporting performance issues, and visualising information. In leading O&G players around the world, basic control room functionality has been enhanced by next generation IOCs that provide proactive support, including integrated planning, optimised decision models, automated procedures, and root cause analysis. This paper describes the features of advanced IOCs and their benefits: improved production (reduced production bottlenecks and increased facility runtime); enhanced organisational capability (increased process standardisation and optimised work processes); reduced risk exposure (e.g. hazardous areas and operator fatigue), reduced operational expenditure (15–25% in maintenance costs and 10–15% in logistics costs). In Australia, advanced IOC functionality and the associated benefits are yet to be widely observed. For an IOC to achieve its full potential, companies must start with a clear vision and business case for building the IOC, and how it will support the operating model. This paper details this and other recommendations that need to be considered, for example, changes to the organisation structure, ways of working, employment model, talent acquisition and development to capture value, and to develop a roadmap that delivers agility for future changes.

Abstract:

Background:Most of the literature on intraoperative consultation (IOC) in gynecologic pathology focuses on the accuracy of this technique. This study addresses a wide range of quality assurance issues regarding this practice through a comprehensive audit of our experience.Design:The anatomic pathology database was searched between 1999 and 2005 for all gynecologic cases who received IOCs. Seven hundred thirty-one IOCs rendered were identified and analyzed. The accuracy of IOC by gynecologic pathologists was comparable to that of surgical pathologists.Results:Patient care was potentially negatively impacted in 14 IOCs; 2 were conducted by the former and 12 by the latter group. Management of ovarian tumors with borderline features significantly improved when the terminology of "at least borderline" was used. Intraoperative consultation by gross inspection only had a low accuracy of 94.7%. Intraoperative consultation was able to definitively and correctly answer the question of whether an ovarian tumor was primary or metastatic in only 35% of patients. As a result of the IOC, the surgical procedure proceeded as originally intended in 96% of patients, was modified in 2%, and was terminated in 2%.Conclusions:This audit identifies certain procedural and communication strategies that can increase accuracy. It also highlights the situations where IOC could be less reliable. Patient's safety can increase by improving the communication between the surgeons and the consultant pathologist, consulting with gynecologic pathologists in oncology cases whenever feasible, and using the term of "at least borderline" rather than "borderline."

Abstract:

This paper revisits the debate between Bickerton on the one hand and Seuren, Corne, Coleman and Curnow on the other on the question of whether serial verb constructions exist in the French creoles of the Indian Ocean (namely Seychelles Creole and Mauritian Creole). It examines data particularly from Mauritian Creole (which was rather marginally represented in that discussion) and argues in agreement with Bickerton (1989, 1996) that serial verbs do indeed exist in this creole just as they do in Seychelles Creole. However, it also argues that their presence in these languages must be attributed not to an innate linguistic mechanism (as claimed in Bickerton 1989, 1996) nor to a substrate source (contra Corne et al. 1996, Corne 1999) but to an independent internal development in which consecutive imperatives were reanalyzed as serial verb constructions. It is assumed that, given the socio-historical nature of creole contact situations, consecutive imperatives would have been a prominent part of early input as interchanges between those who spoke French and those who did not would have mostly been in the form of directives (commands, instructions, etc.) which are more often than not expressed through the imperative . However, it is recognized that this development could have benefited from substrate (particularly Malagasy) influence but it remains in the main the result of an internal diachronic process. The proposal outlined has interesting implications for the role of input and the role that adults may have played in the development of creole languages in general and serial verb constructions in particular. Some aspects of creole languages, it is suggested, can be adequately accounted for without having to implicate either an innate linguistic mechanism or wholesale transfer from substrate sources.

Abstract:

In this article, a DFR framework is proposed focusing on the prioritization, triaging and selection of Indicators of Compromise (IoC) to be used when investigating of security incidents. A core component of the framework is the contextualization of the IoCs to the underlying organization, which can be achieved with the use of clustering and classification algorithms and a local IoC database.

Abstract:

Many current control systems are restricted to highly controlled environments. In complicated dynamic and unstructured environments such as autonomous vehicles, control systems must be able to deal with more and more complex state situations. In complex systems with large number of states, it is often too slow to use optimal planners and developing heuristic tactics for high level goals can be challenging. AI control is an attractive alternative to traditional control architectures due to their capability to approximate optimal solutions in high dimensional state spaces without requiring a human-designed heuristic. Explainable AI control attempts to produce a human readable control command which is both interpretable and manipulable. This paper is an attempt to propose an architecture for explainable AI control in edge-cloud environment in which there are connected autonomous agents that need to be controlled. In this architecture the designed controller is distributed across the edge and cloud platform using explainable AI. This architecture could be introduced as Internet of Control Systems (IoCS), which could be applied as distributed tactics to control of connected autonomous agents. The IoCS attempts to unleash AI services using resources at the edge near the autonomous agents and make intelligent edge for dynamic, adaptive, and optimized AI control.

Abstract:

Abstract Arsenic, a common toxic element is mainly transported in the environment by water. Arsenic in drinking water is of major concern to many of the water utilities in the world. Numerous studies have examined the removal of arsenic from drinking water through treatment processes such as coagulation-precipitation, reverse osmosis and ion exchange. The focus of research has now shifted to solve the problems using suitable adsorbents to achieve low level As in drinking water for communities with high raw water arsenic concentration. The determination of arsenic species is also essential for a better understanding and prediction of the toxic and carcinogenic nature of the species present in natural water systems. It is generally known that As(III) is more toxic than As(V) and inorganic arsenicals are more toxic than organic derivatives. The objective of this study was to study the arsenic adsorption behaviour on iron oxide-coated sand (IOCS) and ferrihydrite (FH). Batch studies were conducted using these adsorbents with natural water containing 325 μg/L arsenic, and the removal of approximately 90% was obtained. The adsorption capacity of the IOCS and FH used in this study for arsenic was estimated as 18.3 and 285 μg/g, respectively. The experimental data fitted well with the well-known isotherms, namely, Freundlich, Langmuir and BET, indicating a favourable adsorption by these adsorbents. Speciation studies were also conducted with natural water containing arsenic. Particulate and soluble arsenic in water were determined, and As(III) in the sample was determined by passing the sample containing arsenic through anion exchange resin (Dowex 1X8-100; acetate form) packed in the column. Speciation studies with natural water showed that the particulate and soluble arsenic contributed 11.4 and 88.6% of the total arsenic present in the natural water, respectively. In the case of soluble arsenic, As(III) and As(V) were 47.3 and 52.7%, respectively.

Abstract:

This conceptual paper explores the implementation of Industry on Campus (IOC) at Sungai Petani Community College (SPCC). The IOC program was implemented based on the original concept developed by the Department of Polytechnic and Community College (JPPKK) through its basic model framework. Implementation of IOCs involving educational institutions with companies from the industry builds strategic collaboration that promotes the development of highly skilled human resource development at the institutional level. In recognizing this aspect, the automotive unit has implemented the IOC model at Sungai Petani Community College for students to take advantage of this concept through Autohauz Prodigy Entrepreneur hub @SPCC. The continued collaboration of companies and institutions for implementing the IOC is expected to contribute to high marketability to enhance the country's social and economic life.

Abstract:

The oil and gas industry is governed by policies with the aim of smoothening the business relationship between the Government, the International Oil Companies (IOC’s) and the Host communities. Different oil producing countries have their own laws governing petroleum activities and these laws vary from country to country based on the B-PEST factors which are Biological, Political, Environmental, Social and Technology. However, reserve size and oil type can also influence petroleum laws. Countries like Nigeria relies strongly on petroleum bills such as the PIB in which this research will be analyzing the Production Sharing Contract (PSC) which is a significant subset of the PIB. Comparison between the existing PSC of Malaysia and that of Nigeria was captured in this research and the analysis of the PSC was done based on the Government Take, National Oil Company (NOC) and the Contractor’s benefits. 26.67% and 56.58% recovery cost, 28.67% and 26.28% Government revenue, 23.14% and 7.64% NOC share, 21.52% and 9.50% Contractor share of revenue per barrel was arrived at for Malaysia and Nigeria respectively, showing that the Malaysian PSC model yields more income to the country when compared to that of Nigeria without necessarily short-changing the contractors or the IOCs. Finally, the reasons behind these deficits were highlighted and recommendations made to improve the PSC and benefits for all parties to the contractual agreements.

Abstract:

This paper provides an assessment and a review of the national oil companies’ (NOCs) business models, challenges and opportunities, their strategies and emerging trends. The role of the national oil company (NOC) continues to evolve as the global energy landscape changes to reflect variations in demand, discovery of new ultra-deep water oil deposits, and national and geopolitical developments. NOCs, traditionally viewed as the custodians of their country’s natural resources, have generally owned and managed the complete national oil and gas supply chain from upstream to downstream activities. In recent years, NOCs have emerged not only as joint venture partners globally with the major oil companies, but increasingly as competitors to the International Oil Companies (IOCs). Many NOCs are now more active in mergers and acquisitions (M&A), thereby increasing the number of NOCs seeking international upstream and downstream acquisition and asset targets

Abstract:

Abstract This article presents an analysis of how China will participate in the ‘shale revolution’ through Sino-foreign collaboration by evaluating the legal arrangements on offer today in the onshore shale gas industry—specifically focusing on the essence of the different agreements, the obstacles for foreign investors under the current petroleum regime, why obstacles exist and what the relevant solutions to them might be. The first part of the article provides a general introduction to the use of JV contracting models and PSCs in the development of Chinese shale projects with foreign investment, and analyses the crucial factors which apply to determining the boundaries between the different forms of contract and the concerns of the relevant parties in the process of negotiation. The second part of the article investigates the reasons for the absence of IOCs in the second shale gas bid round, and why Shell terminated its PSC with CNPC even though commerciality had been declared. Finally, taking into account the underlying reasons for why China's legal regime hinders foreigner investors' enthusiasm for shale gas investment, it proposes relevant suggestions to enhance the attractiveness of Sino-foreign shale gas cooperation.

Abstract:

Long-term exposure to low arsenic concentrations in drinking water causes different diseases including cancer. Hundreds of millions of people worldwide are exposed to arsenic in drinking water. Within Europe, Hungary, Serbia and Croatia are likely most affected. Elevated arsenic concentration has been found in several wells used by the Water Supply Company in Makó, Hungary. Groundwater in southern Hungary typically contains also ammonia, methane, some iron and manganese. Situation is very similar in several other surrounding countries. There are intensive efforts to find affordable approach for treatment of such complex arsenic contaminated groundwater. UNESCO-IHE has been developing an innovative arsenic removal technology (IHE ADART), based on adsorption on iron oxide coated sand (IOCS) and an in-situ regeneration of exhausted adsorbent. The paper presents results from field-testing of the IHE-ADART technology in Southern Hungary. Two pilot plants have been operated at several arsenic-contaminated wells with arsenic concentrations from 20 to 260 μg/l. Very consistent arsenic removal below 10 μg/l was achieved at all testing wells and throughout the 18 months of continuous testing. In addition methane, ammonia, iron and manganese were removed highly effectively. Life cycle cost analysis showed that overall treatment costs would be below 0.10 Euro/m3.

Abstract:

It is encouraging to note that a number of international oil companies (IOCs) have taken an interest in Australian onshore exploration, including the following: Bowen-Surat Basin—BG, ConocoPhillips, CNOOC, PetroChina, Sinopec, KOGAS, Mitsui, Petronas, Shell, and Total.Canning Basin—Mitsubishi, ConocoPhillips, Hess, PetroChina, and Apache.Cooper-Eromanga Basin—BG, and Chevron.Galilee Basin—CNOOC.Georgina Basin—Statoil, and Total. There is now greater interest in Australian onshore exploration, including in a number of sedimentary basins that have previously largely been overlooked. New views on geology and the development of a commercial shale and tight gas sector in the US have prompted a reassessment of onshore petroleum potential, especially in SA, the NT and WA. Access to onshore acreage in Australia for petroleum exploration is, in most jurisdictions, by means of a formal release process with a work program bidding system. Acreage that is being made available for exploration will generally be accompanied by information regarding its geological setting and petroleum prospectivity. Previous exploration activity may be summarised (including information in relation to the amount of pre-existing data available to applicants for acreage), and relevant maps and figures may be included. The following is a compilation of material supplied by the states and NT in relation to onshore acreage being made available for petroleum exploration.

O presente artigo trata das imagens construídas sobre o sertanejo, desde as narrativas do Instituto do Ceará até a criação do campo de concentração do Alagadiço, na seca de 1915. Para isso, analisaremos como o Instituto do Ceará, criado em 1887, através da sua Revista do Instituto do Ceará, vinculou o pioneirismo cearense em relação à abolição da escravatura também ao fato da província ser acometida pela seca. A ideia da natureza ser condicionante da vida da região e ser uma narrativa construída historicamente para retratar o Ceará, fez parte do pensamento da elite que estava à frente do Instituto, e é parte fundamental do que se vai narrar sobre os sertões, os sertanejos, seus costumes, seus modos de ser e agir nos anos posteriores. Nesse sentido, a seca ganha espaço como campo de lutas que também são simbólicas, e justificam medidas segregadoras e excludentes como o campo de concentração do Alagadiço. Por meio de ofícios e relatórios do governo e da Inspetoria de Obras Contra as Secas (IOCS), propomos uma reflexão acerca dos discursos que estavam na ordem do dia na seca de 1877 e que fizeram parte da narrativa da própria criação do campo do Alagadiço em 1915.

Abstract:

Since the discovery of Crude Oil in 1875, the Petroleum Industry has gradually improved in value due to the series of valuable products gotten from crude oil. The significant impact of crude oil as a source of energy has made exportation and importation of this mineral a lucrative business around the world, having turned to be the major source of revenue for most producing countries. Crude oil has contributed to about 80% of Nigerian Government revenue and foreign exchange since 1958, making it a key player in the economic plan of the country. Its importance in Nigeria has made the Legislature introduce lots of policies and laws governing the Oil and Gas business in the country. However, Nigerians with different views over the years have clamored for an improvement of these policies to enable the benefits of Her resources fairly get to the grassroots, producing communities and states while improving foreign investment policies in the country. These demands led to the introduction of the Petroleum Industry Bill (PIB) in the year 2000. This research work attempts to review and offer recommendations for improvements to avoid future litigations, violence, conflicts, and industry fragility. This work will also elaborate on different steps taken by the Nigerian Government over the years to implement this bill, challenges faced by the Government and International Oil Companies (IOCs), Government and its citizens, and anomalies seen in the bill up till status quo.

Abstract:

Nigeria discovered crude oil in 1956. Instead of making sustainable economic progress since, the country spiraled into serious economic waste and loss, due to pollution from crude oil, corruption, neglect of the oil producing regions and high handedness of the IOCs/NOCs. Today, not only are legitimate oil exploration pipelines leaking oil into the environment, illegal artisanal refineries are contributing to pollution problems and by extension economic and health effects. This study thus investigated, effects of artisanal refinery on the environment, public health and socio-economic development of communities in the Niger Delta Region. The cross-sectional research design was used in this study. The target population comprised of illegal bunkering/artisanal refining sites and households that dwell within the artisanal refinery sites. The Taro Yamane formula was used to determine the sample sizes for state and 400 was realized for each state. 1324 artisanal refining sites were determined and using Taro Yamane equation 313 sites were derived. The Kruskal-Wallis H test was used for data analysis. The study found that, locals complained about how artisanal refineries affected their environment, health and economics. These effects varied spatially based on the result of the Kruskal Wallis test at P<0.05. However, some of the locals identified that, despite the environmental pollution because of illegal artisanal refining in the area, some economic gains abound. It is therefore the position of this study that artisanal refining be improved, so that the environmental and health effects be reduced, while making room for sustainable economic development.

Abstract:

Abstract Environmental Effects Monitoring (EEM) Programs in Canada have been developed for the pulp and paper and metal mining industries. The EEM Program conducts cyclical evaluations of receiving environments to determine whether effects exist when facilities comply with existing regulations. Investigation of cause (IOC) is a specific stage in the EEM Program that is used after environmental effects in fish and/or benthos have been detected, confirmed and their extent and magnitude have been documented. This paper presents an overview of the processes associated with this phase of monitoring. The objective of an IOC is to obtain sufficient information so that the source of the effect can be identified and removed, or its effects reduced to an acceptable level. The initial direction of an IOC is dependent upon the type of response patterns observed for fish and/or benthos during EEM cycles and extent/magnitude studies. The framework presented in this paper is based on an amalgamation of research projects conducted at Canadian pulp mills over the last decade and selected studies are summarized as examples. It also represents an integration of several research philosophies and scientific disciplines. The framework is based on national response patterns from the second cycle of pulp and paper EEM studies. IOCs are directed into either an eutrophication-based investigation or a contaminant-based investigation (including metabolic disruption in fish). The framework is constructed with a progression of investigative levels designed to provide more information on the causative factors. Each of these phases also represents a decision point for stakeholders to determine if sufficient information has been attained about the causal factor(s) and whether the IOC should be concluded. It is expected that the framework will evolve with a growing knowledge base of causal factors, as facilities enter into this phase of the EEM Program.

Abstract:

The ISWI class of proteins consists of a family of chromatin remodeling ATPases that is ubiquitous in eukaryotes and predominantly functions to slide nucleosomes laterally. The yeast Saccharomyces cerevisiae Isw1 partners with several non-essential alternative subunits — Ioc2, Ioc3, or Ioc4 — to form two distinct complexes Isw1a and Isw1b. Besides its ATPase domain, Isw1 presents a C-terminal region formed by HAND, SANT, and SLIDE domains responsible for interaction with the Ioc proteins and optimal association of Isw1 to chromatin. Despite diverse studies on the functions of the Isw1-containing complexes, molecular evidence for a regulation of this chromatin remodeling ATPase is still elusive. Results presented here indicate that Isw1 is not only ubiquitylated but also strongly SUMOylated on multiple lysine residues by the redundant Siz1/Siz2 SUMO E3 ligases. However, Isw1 is a poor substrate of the Ulp1 and Ulp2 SUMO proteases, thus resulting in a high level of modification. Extensive site-directed mutagenesis allowed us to identify the major SUMOylation sites and develop a SUMO-defective mutant of Isw1. Using this molecular tool, we show that SUMOylation of Isw1 specifically facilitates and/or stabilizes its interaction with its cofactor Ioc3 and consequently the efficient recruitment of the Isw1–Ioc3 complex onto chromatin. Together these data reveal a new regulatory mechanism for this fascinating remodeling factor.

Abstract:

AbstractStaatsolie Maatschappij Suriname N.V., together with the gold mining industry, has gradually become a major contributor to the Surinamese economy since the decline of the alumina industry. In the last 35 years, about 110MMbbls (million barrels) of crude oil have been produced. Staatsolie is now in the early stages of fulfilling its VISION 2030, which is not only aimed at increased exploration and production but also at power generation, further diversification and regional expansion. The basis for achieving these goals is accelerated on- and offshore exploration, followed by growth in production. The offshore region remains a frontier area, with only a few wells drilled. Current production is about 17,000bopd (barrels of oil per day). Between 2007 and 2014, Staatsolie has spent about US$120 million on exploration. An integrated study for the Suriname–Guyana Basin carried out by Staatsolie in 2009 demonstrated the upside potential of this basin from a source rock potential perspective, which has been proven by both the Liza-1 oil discovery offshore of Guyana in 2015 and the Zaedyus-1 oil discovery offshore of French Guiana in 2011.Staatsolie is now focusing its efforts on the near-shore area, where it recently concluded a five-well drilling programme, following a 3-D seismic survey. In the deep offshore area, international oil companies (IOCs) are actively pursuing the next discovery in the Atlantic Margin, partly driven by the conjugate-margin theory geologically linking South America and West Africa.Staatsolie is also attempting to increase recovery from the most mature and largest oilfield, the Tambaredjo Field, through Enhanced Oil Recovery (EOR) technologies of which polymer flooding is deemed the most suitable, with estimated potential incremental recovery of up to 12%.Staatsolie recognises the role of a highly skilled and motivated workforce and therefore continues investing in its people through internal as well as external training. Thirty-five years after it was founded by Mr Eddy Jharap, a geologist by training and the first Managing Director of the company, it can be stated that Staatsolie has taken its place in Surinamese society as a significant contributor to the economy, a preferred employer, a nucleus for industrial spin-off and an example for other companies.

Abstract:

AbstractThe influence of temperature on the sorption of As(III) onto iron oxide coated quartz sand (IOCQS) was studied in the temperature range of 298–318 K. An increase in temperature was found to have positive influence on the adsorption of As(III) ions onto IOCQS surfaces because of increased diffusion of As(III) ions into the pores of IOCQS at higher temperature. The enhanced sorption at higher temperature indicated endothermic adsorption process. Equilibrium isotherms for the adsorption of As(III) on IOCQS were analyzed at different temperatures. Among the conventional isotherms, Freundlich isotherm best predicted specific uptake at different temperatures, followed by Redlich–Peterson, Langmuir and Temkin isotherm models. Various thermodynamic parameters namely heat of adsorption (∆H0), change in entropy (∆S0), and Gibbs free energy change (∆G0) were computed from the equilibrium constant (KD) values. The results indicated positive value for heat of adsorption ∆H0, a positive ∆S0 and a negative ∆G0. Finally, the isosteric heat of adsorption (ΔHst,a) values were calculated and quantitatively correlated with the fractional loading of As(III) onto IOCQS. The surface heterogeneity of adsorbents could be quantitatively described with an isosteric enthalpy function of fractional loading based on Do and Do model. The results show that the IOCQS possesses heterogeneous surface with sorption sites having different activities.

Abstract:

ABSTRACT The SANT domain is a nucleosome recognition module found in transcriptional regulatory proteins, including chromatin-modifying enzymes. It shows high functional degeneracy between species, varying in sequence and copy number. Here, we investigate functions in vivo associated with two SANT motifs, SANT and SLIDE, in the Saccharomyces cerevisiae Isw1 chromatin-remodeling ATPase. We show that differences in the primary structures of the SANT and SLIDE domains in yeast and Drosophila melanogaster reflect their different functions. In yeast, the SLIDE domain is required for histone interactions, while this is a function of the SANT domain in flies. In yeast, both motifs are required for optimal association with chromatin and for formation of the Isw1b complex (Isw1, Ioc2, and Ioc4). Moreover, nucleosome remodeling at the MET16 locus is defective in strains lacking the SANT or SLIDE domain. In contrast, the SANT domain is dispensable for the interaction between Isw1 and Ioc3 in the Isw1a complex. We show that, although defective in nucleosome remodeling, Isw1 lacking the SANT domain is able to repress transcription initiation at the MET16 promoter. Thus, chromatin remodeling and transcriptional repression are distinct activities of Isw1.

Abstract:

Due to the unique properties of metal dichalcogenides, they are wide used in various fields of nano- and optoelectronics. Bi2Se3 is one of the promising n-type semiconductor materials belonging to the Av – Bvı group, with a band gap of 0.3 eV. To obtain these compounds by co-electrodeposition, we study the electroreduction of the initial components separately. Therefore, the study is devoted to the electrochemical reduction of selenite ions from the ethylene glycol solution. By drawing cyclic and linear polarization curves on Pt electrodes, the kinetics, the mechanism of the process, and the influence of various factors on the electroreduction of selenite ions are studied. Using the obtained data on the influence of temperature, the effective activation energy was calculated by the Gorbachov method. The calculation results show that the electroreduction of selenite ions from ethylene glycol is accompanied by electrochemical kinetics closer to diffusion
