THE PURPOSE. Determination of effective methods of carbon dioxide capture and utilization, search for promising solutions and testing of carbon dioxide capture methods at a laboratory facility. The most popular absorption methods of CO2 capture, in which the gas reacts with a liquid absorbent.METHODS. The laboratory setup includes the CO2 source itself (gas cylinder), an absorber, and a flask with sodium hydroxide solution to analyze absorption efficiency. Efficiency is evaluated by the titrimetric method, where a solution of hydrochloric acid is used as a titrant, phenolphthalein and methyl orange act as indicators.RESULTS. For the analysis, available absorbents were selected, which are available at most thermal power plants. As a result of a laboratory experiment, it was found that a quicklime suspension of 6% has the highest sorption capacity.CONCLUSION. The decarbonization of the industrial energy sector is a complex process that requires global changes in fuel policy, namely the transition to carbon-free energy resources. An alternative energy resource is hydrogen energy, but even here carbon dioxide emissions are present. Capture and disposal will help decarbonize the main sources of pollution. Industrial carbon dioxide capture has great potential, which lies in the variety of uses of sorption materials.

Published: January 2023

Background There is an age-old notion that family planning is women’s responsibility disregarding the fact that men have equal responsibility in fertility regulation. Although male involvement is getting more recognition, studies on men’s role in family planning are very few in the number in this part of the world.
Objective To assess the knowledge, attitude and level of male involvement in family planning and to find out the factors associated with male involvement by contraceptive usage.
Method A community based cross-sectional study was done from May to July 2021 among 165 currently married male, who had at least one child, living in Singur district of West Bengal. Cluster sampling method was done to select study participants and data were collected by pre-designed pretested questionnaire. Descriptive statistics, multivariable logistic regression was applied and data were analysed applying SPSS software.
Result Only 36.4% participants were directly involved in family planning either by using condom or by withdrawal method but 65.5% participants were indirectly involved in family planning through spousal communication either by approving contraceptive use to their spouse or by decision making regarding family planning. Moreover, barrier of contraceptives usage were side effect (27%) and fear of impotence (25.5%). Male involvement was significantly associated with participant’s education [AOR (95% CI= 3.63 (1.45-9.05)], caste [AOR (95% CI= 7.06 (2.55-19.51)], number of living children [AOR (95%CI= 5.01(1.95-12.87)], desire for more child [AOR (95% CI=0.34 (.13-.87)] and attitude on family planning [AOR (95% CI= 3.55 (1.41-8.94)].
Conclusion This study identified the prevailing gender norms in rural areas. Advocacy for male involvement in family planning by health personnel during counselling of eligible couples should help in increasing contraceptive coverage in the long run.

Provision of insufficient compensation for community land and/or buildings submerged in the Lapindo mudflow presents a challenge in providing clarity on settlement information and the legal status of the land. The social and legal challenge for settling compensation is faced with discrimination in payment of the Map of the Affected Area, including the status of the land after the disaster. A qualitative method was used in this study, along with a literature search. A total of 54 secondary data points were collected and descriptively analyzed in order to validate the compensation process and evaluate the legal status of the land in accordance with laws and regulations. According to the findings, the government has declared the area that sank as a natural disaster as a result of the Lapindo mudflow. The government and the company are responsible for dealing with the disaster, with all compensation funding coming from the State Revenue and Expenditure Budget (APBN) and other legitimate funding sources. Plots of land owned by the community that were submerged in mud were classified as destroyed land because the community was unable to maintain and maintain the identity of the physical form, location, boundaries, area, shape, and function of their land rights. In the future, the silted-up expanse of land will have the status of state land, and the state will be able to grant land rights to the community or parties in need by applying for rights.

Pemberian ganti kerugian yang belum tuntas terhadap tanah dan/atau bangunan milik masyarakat yang terendam lumpur Lapindo menimbulkan tantangan untuk memberikan kejelasan informasi penyelesaiannya dan status hukum tanahnya. Tantangan sosial dan legal untuk penyelesaian ganti kerugian tersebut dihadapkan pada diskriminasi pembayaran atas Peta Area Terdampak termasuk status tanah pasca kejadian bencana. Penelitian ini menggunakan metode kualitatif dengan penelusuran pustaka. Sejumlah 54 data sekunder yang terkumpul dianalisis secara deskriptif untuk memvalidasi proses ganti kerugian dan mengevaluasi status hukum tanah yang sesuai peraturan perundangan. Hasilnya menunjukkan bahwa pemerintah menetapkan area yang tenggelam akibat semburan lumpur Lapindo sebagai bencana alam. Pemerintah dan pihak perusahaan bertanggung jawab menanggulangi bencana tersebut dengan segenap pembiayaan ganti kerugian dari Anggaran Pendapatan Belanja Negara (APBN) dan sumber pendanaan lainnya yang sah. Bidang-bidang tanah milik masyarakat yang terendam lumpur dikategorikan sebagai tanah musnah karena masyarakat tidak mampu menjaga dan memelihara identitas wujud fisik, letak, batas, luas, bentuk, dan fungsi hak atas tanahnya. Pada masa depan, hamparan tanah karena endapan lumpur tersebut berstatus sebagai tanah negara dan negara dapat kembali memberikan hak atas tanah kepada masyarakat atau pihak yang membutuhkan dengan permohonan hak.

OBJECTIVE
Current knowledge about venous hypertensive myelopathy (VHM) is incomplete. This study was performed with the aim of clarifying the clinical features and outcomes of craniocervical VHM.

METHODS
This retrospective, single-center cohort study included 65 patients with craniocervical junction arteriovenous fistulas resulting in VHM treated in Xuanwu Hospital from January 1, 2002, to December 30, 2020. All patients underwent microsurgery or endovascular treatment. The primary outcome was neurological function assessment using the Japanese Orthopaedic Association (JOA) scale, modified Aminoff-Logue Scale (mALS), and Venous Hypertensive Myelopathy Scale (VHMS). The secondary outcomes were recurrences and postoperative adverse events. Pearson linear regression and receiver operating characteristic curves were used to evaluate the relationships among the three scales. Kaplan-Meier and multivariate logistic regression analyses were performed to predict outcomes.

RESULTS
The mean patient age was 57.4 ± 11.4 years, and 88% of patients were male. The 1-year follow-up rate was 83.1%, and the 5-year follow-up rate was 50.8%. The VHMS was correlated with the JOA (R2 = 0.6722) and mALS (R2 = 0.7399) and increased the assessment accuracy by approximately 20% when compared with the other two scales. Overall, 25.9% of patients experienced delayed neurological decline beyond the 1-year follow-up. Further logistic regression suggested that age > 65 years was an independent predictor (OR 7.831, 95% CI 1.090–56.266; p = 0.041). Embolic recanalization and new bilateral symmetry feeders were the major reasons for recurrence. Recurrence increased the risk of adverse events after the second surgery (OR 20.455, 95% CI 1.170–357.320; p = 0.039).

CONCLUSIONS
CCJ AVFs resulting in VHM are a rare but deadly complication, and providers should be cautious of age-related delayed neurological decline and strive for a one-time anatomical cure.

OBJECTIVE
Resection of brain metastases (BMs) may be associated with increased risk of leptomeningeal disease (LMD). This study examined rates and predictors of LMD, including imaging subtypes, in patients who underwent resection of a BM followed by postoperative radiation.

METHODS
A retrospective, single-center study was conducted examining overall LMD, classic LMD (cLMD), and nodular LMD (nLMD) risk. Logistic regression, Cox proportional hazards, and random forest analyses were performed to identify risk factors associated with LMD.

RESULTS
Of the 217 patients in the cohort, 47 (21.7%) developed postoperative LMD, with 19 cases (8.8%) of cLMD and 28 cases (12.9%) of nLMD. Six-, 12-, and 24-month LMD-free survival rates were 92.3%, 85.6%, and 71.4%, respectively. Patients with cLMD had worse survival outcomes from the date of LMD diagnosis compared with nLMD (median 2.4 vs 6.9 months, p = 0.02, log-rank test). Cox proportional hazards analysis identified cerebellar/insular/occipital location (hazard ratio [HR] 3.25, 95% confidence interval [CI] 1.73–6.11, p = 0.0003), absence of extracranial disease (HR 2.49, 95% CI 1.27–4.88, p = 0.008), and ventricle contact (HR 2.82, 95% CI 1.5–5.3, p = 0.001) to be associated with postoperative LMD. A predictive model using random forest analysis with an area under the receiver operating characteristic curve of 0.87 in a test cohort identified tumor location, systemic disease status, and tumor volume as the most important factors associated with LMD.

CONCLUSIONS
Tumor location, absence of extracranial disease at the time of surgery, ventricle contact, and increased tumor volume were associated with LMD. Further work is needed to determine whether escalating therapies in patients at risk of LMD prevents disease dissemination.
Rurality index score and pediatric neuro-oncological outcome in Ontario
Authors: Kameda-Smith Michelle Masayo , Pond Gregory R. , Seow Hsien 
Published: January 2023

OBJECTIVE
Rapid access to neurosurgical decisions and definitive management are vital for the outcome of neurocritical patients. There are unique challenges associated with the provision of services required to maintain critical infrastructure for rural citizens. Given that a relationship between rurality, marginalization, and health outcomes has been identified as associated with higher mortality rates and higher rates of many diseases, the authors studied whether worse clinical outcomes were associated with rurality in pediatric neuro-oncological disease.

METHODS
Using linked administrative databases, the authors retrospectively analyzed a population-based cohort of patients diagnosed with a pediatric brain tumor between 1996 and 2017 in Ontario, Canada. The main variable of interest was the Rurality Index for Ontario (RIO; larger value denotes more rural); the main outcome was survival, while controlling for surgery and tumor type.

RESULTS
Of the 1428 patients included, 53.9% were male. Overall survival of all the children (controlling for surgery and tumor type) at 1, 5, and 10 years was 84.7%, 65.1%, and 58.4%, respectively. A total of 11.5% were classified as living in a rural area of Ontario. The distance to the nearest pediatric neurosurgical hospital ranged from 25.6 to 167.4 km. The RIO score was 0 in 38.7% of children, and the majority of patients had a RIO score < 40. A higher RIO score was not a significant factor (continuous p = 0.12/ordinal p = 0.18) associated with length of follow-up, indicating that rurality was not significantly linked to compliance with clinical follow-up.

CONCLUSIONS
Rurality of the region in which pediatric neuro-oncological patients reside was not associated with patient outcome (HR 0.83, p = 0.39).
