Adsorption behavior of CO_(2)/H_(2)S mixtures in calcite slit nanopores for CO_(2) storage:An insight from molecular perspective

It is acknowledged that injecting CO_(2) into oil reservoirs and saline aquifers for storage is a practical and affordable method for CO_(2) sequestration.Most CO_(2) produced from industrial exhaust contains impurity gases such as H_(2)S that might impact CO_(2) sequestration due to competitive adsorption.This study makes a commendable effort to explore the adsorption behavior of CO_(2)/H_(2)S mixtures in calcite slit nanopores.Grand Canonical Monte Carlo(GCMC)simulation is employed to reveal the adsorption of CO_(2),H_(2)S as well as their binary mixtures in calcite nanopores.Results show that the increase in pressure and temperature can promote and inhibit the adsorption capacity of CO_(2) and H_(2)S in calcite nanopores,respectively.CO_(2)exhibits stronger adsorption on calcite surface than H_(2)S.Electrostatic energy plays the dominating role in the adsorption behavior.Electrostatic energy accounts for 97.11%of the CO_(2)-calcite interaction energy and 56.33%of the H_(2)S-calcite interaction energy at 10 MPa and 323.15 K.The presence of H_(2)S inhibits the CO_(2) adsorption in calcite nanopores due to competitive adsorption,and a higher mole fraction of H_(2)S leads to less CO_(2) adsorption.The quantity of CO_(2) adsorbed is lessened by approximately 33%when the mole fraction of H_(2)S reaches 0.25.CO_(2) molecules preferentially occupy the regions near the po re wall and H_(2)S molecules tend to reside at the center of nanopore even when the molar ratio of CO_(2) is low,indicating that CO_(2) has an adsorption priority on the calcite surface over H_(2)S.In addition,moisture can weaken the adsorption of both CO_(2) and H_(2)S,while CO_(2) is more affected.More interestingly,we find that pure CO_(2) is more suitable to be sequestrated in the shallower formations,i.e.,500-1500 m,whereas CO_(2)with H_(2)S impurity should be settled in the deeper reservoirs.

Intensive care environment: Perspective of relatives of critically ill patient sustained by health technology

The intensive care unit(ICU)is a complex setting by nature,and some have described it as bizarre due to its numerous sirens that sound when anything is dangerous,constant activity,equipment,bright lights,and high fatality rate.The demands placed on nurses to care for critically ill patients in this environment frequently prevent nurses and other health‑care professionals from acknowledging the feelings of patient’s relatives or family caregivers,resulting in a hostile environment from the patient’s relative’s perspective.When a patient’s family enters the ICU,they feel that hospital administrators do little to nothing to alleviate their discomfort and fear.Despite research demonstrating the importance of providing a homely environment for patients’families,In Nigeria ICU is still far behind how a conventional ICU environment should be structured to accommodate patient’s relations in the unit.The goal of this study was to look at the patient’s relative’s perspective on providing care for a critically ill patient in an ICU,with a focus on the unit’s complexity and overall experience.Based on the findings of this study,we recommend that hospital administrators ensure that the environment of the upcoming ICU is designed to meet the needs of patient’s relatives by addressing identified environmental concerns,like caring neglect,by providing a friendly and stress‑free environment.

The Dilemma and Way Out of China’s Participation in the Development of Marine Genetic Resources in ABNJ from the Perspective of BBNJ

The fifth intergovernmental negotiations on marine BBNJ(Biodiversity beyond Areas of National Jurisdiction)concluded in August 2022,in which there are still major differences regarding access to marine genetic resources,management,and technology transfer.China’s participation in the development of marine genetic resources in ABNJ(areas beyond national jurisdiction)has many dilemmas,which are linked to the difficulties faced in advancing the BBNJ negotiations.The following countermeasures are proposed at the institutional and practical levels respectively:clarifying the legal attributes and applicability of the principles of marine genetic resources;establishing mechanisms for access,management,environmental impact assessment and benefit sharing of marine genetic resources;and using the“Blue Partnership”to build a governance mechanism for marine genetic resources to achieve mutual benefits.

Outcomes and patients' perspectives of transition from paediatric to adult care in inflammatory bowel disease

AIM: To describe the disease and psychosocial outcomes of an inflammatory bowel disease (IBD) transition cohort and their perspectives.METHODS: Patients with IBD, aged > 18 years, who had moved from paediatric to adult care within 10 years were identified through IBD databases at three tertiary hospitals. Participants were surveyed regarding demographic and disease specific data and their perspectives on the transition process. Survey response data were compared to contemporaneously recorded information in paediatric service case notes. Data were compared to a similar age cohort who had never received paediatric IBD care and therefore who had not undergone a transition process.RESULTS: There were 81 returned surveys from 46 transition and 35 non-transition patients. No statistically significant differences were found in disease burden, disease outcomes or adult roles and responsibilities between cohorts. Despite a high prevalence of mood disturbance (35%), there was a very low usage (5%) of psychological services in both cohorts. In the transition cohort, knowledge of their transition plan was reported by only 25/46 patients and the majority (54%) felt they were not strongly prepared. A high rate (78%) of discussion about work/study plans was recorded prior to transition, but a near complete absence of discussion regarding sex (8%), and other adult issues was recorded. Both cohorts agreed that their preferred method of future transition practices (of the options offered) was a shared clinic appointment with all key stakeholders.CONCLUSION: Transition did not appear to adversely affect disease or psychosocial outcomes. Current transition care processes could be optimised, with better psychosocial preparation and agreed transition plans.

Experience of the patient's success in facing post-stroke urinary incontinence: the patient's perspective

Objective:Post-stroke urinary incontinence(UI)is one of the sequelae of stroke.This situation affects all aspects of the patient’s life–physically,psychologically,socially,and spiritually.This study aimed to investigate the experience of patients’success in facing a post-stroke UI.Methods:A qualitative study using the Rapid Assessment Procedure(RAP)approach was used in this study.Informants were selected using purposive sampling.In-depth interviews with as many as 8 patients who had recovered from post-stroke UI and living in the greater area of Southeast Sulawesi(Indonesia)were conducted.In-depth interviews were also conducted with 8 caregivers and 2 nurses.Data were analyzed using a thematic analysis approach and interpretation of data was based on Humanbecoming theory and Self-care deficit theory of nursing.Results:Five successful things the patients experienced during post-stroke UI were identified.The five successes were as follows:they provided information to get to know and understand post-stroke UI,followed the procedures to overcome post-stroke UI,conducted self-control exercises and stayed motivated,performed daily activities independently according to ability,and made use of family suppor t and peers’attention.Conclusions:These findings indicated that persistence,belief,independence,and social support(family and peer)made patients to successfully face their post-stroke UI and improved their quality of life.These findings also became the basis for developing a poststroke UI management model based on Humanbecoming theory and Self-care deficit theory of nursing.

Pediatric stricturing Crohn's disease

Crohn’s disease(CD)is a chronic inflammatory disease of the digestive tract.The incidence of pediatric CD is increasing and is currently 2.5-11.4 per 100000 world-wide.Notably,approximately 25%of children with CD develop stricturing CD(SCD)that requires intervention.Symptomatic stricturing diseases refractory to pharmacological management frequently require non-pharmacological interventions.Non-pharmacological therapeutic strategies include endoscopic balloon dilatation,stricturoplasty,and surgical resection of the strictured seg-ment.However,strictures tend to recur postoperatively regardless of treatment modality.The lifetime risk of surgery in patients with childhood SCD remains at 50%-90%.Thus,new and emerging strategies,advanced diagnostic tools,and minimally invasive approaches are under investigation to improve the outcomes and overall quality of life of pediatric patients with SCD.

Glyco-sphingo biology: a novel perspective for potential new treatments in Huntington's disease

Huntington＇s disease （HD） is the most common dominantly inherited neurodegenerative disorder, mainly characterized by the progressive striatal and cortical neurodegeneration and as- sociated motor, cognitive and behavioural disturbances （Zuccato et al., 2010）. The disease-causing mutation is an expansion of a GAG trinucleotide repeat （〉 36 repeats） encoding a polygluta- mine stretch in the N-terminal region ofhuntingtin （Htt） （Zuc- cato et al., 2010）, a ubiquitous protein whose function is still unclear （Zuccato et al., 2010）. Expansion of the polyQ stretch endows mutant Htt （mHtt） with toxic properties, and results in the development of a broad array of undesirable effects in both neuronal and non-neuronal cells （Zuccato et al., 2010）. Among all cellular dysfunctions and biochemical imbalances classically associated with HD, perturbed metabolism of （glyco） sphingolipids appears to play a crucial role in the pathogenesis of the disease. Over the last years, we and other have extensively contributed to these findings （Desplats et al., 2007;

Customer Retention: Behaviour Perspective Model of Ghanaian Telecommunication Industry Using Multinomial Regression Analysis

To stay competitive, the mobile telecommunication companies spend millions of Ghana cedi each year on building long-term relationships with their customers. Marketing managers are constantly challenged with the problem of where to channel the limited resources in order to retain existing customers. This study approaches the customer retention problem in the mobile phone sector from a behavioural perspective, applying the Behavioural Perspective Model as the main analytical framework and further exploits some other factors that influence customer retention. The model includes a set of pre-behaviour and post-behaviour factors to study consumer choice, and explains its relevant drivers in a viable and comprehensive way, grounded in radical behaviourism. Data for the analysis were collected from tertiary students from Accra and Takoradi. Data collected were analysed using the multinomial regression technique. Analysis of the data revealed that the Behaviour setting factor is the only significant element in Behaviour Perspective Model. Further exploitation of behaviour situation revealed that the number of networks a customer uses, previous experience of a customer and customer’s intention are significant factors in determining customer retention in Ghana’s mobile telecommunication industry.

＂Going Global＂ Strategies of Chinese Culture from the Audience＇ s Perspective

This paper revealed American students'interest in Chinese culture potentially due to China's recent development.Moreover,participants reported that understanding Chinese culture would broaden their perspective to include customs which were perceived as quite different from their own.Unsurprisingly,all of the participants were interested in superficial experiences with Chinese culture,like eating Chinese food.More than half of the participants indicated a desire to visit historical sites,such as the Great Wall and the Forbidden City.Half of the participants would like to travel in big cities such as Beijing and Shanghai,if they were to visit China.Not a few of Chinese descendants were eager to go to China for tracing roots.According to the results of the research,some"going global"strategies of Chinese culture were provided.The results may impact on Chinese culture's"going global"trend and offer support to the spread of Chinese culture.
