In-situ conversion presents a promising technique for exploiting continental oil shale formations,characterized by highly fractured organic-rich rock. A 3D in-situ conversion model, which incorporates a discrete fracture network, is developed using a self-developed thermal-flow-chemical(TFC) *** of the model elucidates the in-situ conversion process in three stages and defines the transformation of fluids into three distinct outcomes according to their end stages. The findings indicate that kerogen decomposition increases fluid pressure, activating fractures and subsequently enhancing permeability. A comprehensive analysis of activated fracture permeability and heating power reveals four distinct production modes, highlighting that increasing heating power correlates with higher cumulative fluid production. Activated fractures, with heightened permeability, facilitate the mobility of heavy oil toward production wells but hinder its cracking, thereby limiting light hydrocarbon ***, energy efficiency research demonstrates the feasibility of the in-situ conversion in terms of energy utilization, especially when considering the surplus energy from high-fluctuation energy sources such as wind and solar power to provide heating.

Breast cancer is considered one of the most common cancers among women, accounting for 25% - 29% of new cases worldwide each year. The diagnosis, living with the disease, as well as the different treatments can have important impacts on the Psychological and mental health of patients. Objective: To investigate the psychological aspects that women with breast cancer develop or may develop. Methodology: A systematic review using the PRISMA methodology was used. Results: 11 articles that met the inclusion and exclusion criteria were analysed. The largest flow of publications in relation to the effects of the patient with cancer, were carried out between the years 2000 and 2023. Conclusions: Psychological disorders (depression, anxiety, stress) are part of the lives of women diagnosed with breast cancer, and their prevalence varies from one woman to another.

Disorders of glucose homeostasis, such as stress-induced hypoglycemia and hyperglycemia, are common complications in patients in the intensive care unit. Patients with preexisting diabetes mellitus(DM) are more susceptible to hyperglycemia, as well as a higher risk from glucose overcorrection, that may results in severe hypoglycemia. In critically ill patients with DM, it is recommended to maintain a blood glucose range between 140-180 mg/d L. In neurological patients and surgical patients, tighter glycemic control(i.e., 110-140 mg/d) is recommended if hypoglycemia can be properly avoided. There is limited evidence that shows that critically ill diabetic patients with a glycosylated hemoglobin levels above 7% may benefit from looser glycemic control, in order to reduce the risk of hypoglycemia and significant glycemic variability.

This study investigated the adsorption of Hg（Ⅱ） on Macrocystis pyrifera and Undaria pinnatifida in monometallic system in the presence of Zn（II）,Cd（Ⅱ） and Ni（II）.The two biosorbents reached the same maximum sorption capacity （q m = 0.8 mmol/g） for *** showed a greater affinity （given by the coefficient b of the Langmuir equation） for mercury compared to *** （4.4 versus 2.7 L/mmol）.Mercury uptake was significantly reduced （by more than 50%） in the presence of competitor heavy metals such as Zn（II）,Cd（II） and Ni（Ⅱ）.Samples analysis using an environmental scanning electron microscopy equipped with an energy dispersive X-ray microanalysis showed that mercury was heterogeneously adsorbed on the surface of both biomaterials,while the other heavy metals were homogeneous *** analysis of biosorbents by Fourier transform infrared spectrometry indicated that Hg（Ⅱ） binding occurred on S=O （sulfonate） and N-H （amine） functional groups.
