The article describes the necessary conditions for the phenomenon of thermal energy release in a magnetic fluid placed in a high-frequency rotating magnetic field. The minimum amplitude of the magnetic field was calculated and the thermal power released (by the rotating spherical nanoparticles in the viscous medium) was estimated. The estimations were based on the assumption that the magnetic relaxation times (τN and τB) and the magnetic field rotation period (τrot) meet the condition: τN>>τrot>>τB. The principle of operation and construction of the device generating a high-frequency rotating magnetic field is described. Preliminary experimental studies were carried out using a magnetic fluid with magnetite nanoparticles that indicated magnetic relaxation as the cause of the released heat. The value of the absorption rate in the experiment and its dependence on the strength of the magnetic field were determined.

Objective: The FITT (Frequency, Intensity, Time, and Type) principle is an effective foundation in EP. However, the CORRECT components; C–Combination of interventions, O–Order of the Interventions, R–Repetitions, R–Rest period between sets and between sessions, E–Exercise at home, C–Cognitive domain, T–Total dose and re-evaluation plans, should be considered. The purpose of this paper was to describe the updated dynamic and evidence based FITT-CORRECT principle of EP and demonstrates its application using a case study. Results: Literatures, related to EP, clinical reasoning and clinical decision-making, were critically reviewed. Established evidence is summarized to describe an updated dynamic and evidence-based principle of EP. The gaps within the FITT and other related principles of EP are addressed. The FITT-CORRECT principle was introduced and an effective outcome of the updated principle was demonstrated using a case study. The FITT-CORRECT principle integrates many components that are missing in the FITT and other related EP principles. Based on the reported case study, the FITT-CORRECT principle of EP should optimize patients’ intervention outcomes. Physiotherapists can potentially improve their EP by utilizing the FITT-CORRECT in clinical practice.

Oguta LGA is surrounded by 44 oil wells located around different communities. Preliminary investigations indicated that crude wastes were not properly managed and oil spillage occurred regularly in the LGA. Therefore, assessment of both radionuclide contents in yam matrix and health risks in Oguta was carried out to determine possible radiological health risks associated with improper management of crude wastes, and also evaluate haematological health profile in the LGA for future reference and research. A well calibrated NaI (Tl) detector was deployed for the radiological investigation, and about 5 ml of blood samples were collected from 190 participants each from Oguta and the control LGAs for haematological assessment. Mean activity concentrations due to 40K, 226Ra and 232Th in yam samples from Oguta LGA were 189.99 ± 59.14 Bqkg-1, 23.75 ± 5.69 Bqkg-1 and 30.99 ± 9.51 Bqkg-1, respectively while mean activity concentrations due to natural radionuclides in yam samples from control LGA were 110.40 ± 78.53 Bqkg-1, 10.12 ± 3.34 Bqkg-1 and 18.39 ± 8.74 Bqkg-1 for 40K, 226Ra and 232Th, respectively. Committed effective dose equivalent values in Oguta and the control LGAs were 704.95 ± 183.30 μSvy-1 and 403.65 ± 172.19 μSvy-1, respectively which are less than world average value of 1.1 mSvy-1. Crucially, one-way ANOVA at α0.05 has indicated that effects of radiological parameters due to natural radionuclides in yam from Oguta are significantly different from effects of radiological parameters due to natural radionuclides in yam from the control LGA. However, the percentage contributions of natural radiation exposures to incidence of cancer in Oguta and the control LGAs are just 1.7% and 1.4%, respectively, and haematological investigations have shown that overall health of the communities in the study LGAs has not been compromised due to environmental and human factors. Hence, natural radioactivity may have been elevated in Oguta but the concentration levels are not yet alarming. Radiological health risks could result from consistent exposure to those natural radionuclides in the long term.

Aim: To compare the expectations and the reality of oncology patients in terms of to the use of medical cannabis, including symptom control and related quality of life. Research question: Is there a difference between oncology patients expectations and their reality concerning the use of medical cannabis and what do oncology patients experience regarding symptom control and quality of life? Method: This research was done in a tertiary hospital in Israel at the oncology clinic A comparative study that used self- administered questionnaires for patients who received authorization to use medical cannabis. The first questionnaire was given to patients after receiving the authorization to use medical cannabis and asked about their expectations related to its use. Patients filled out the same questionnaire for the second time, approximately two months after. Comparison of the respondent’s answers, before and after using medical cannabis, showed reality of improving symptom control and Quality of Life. Results: Seventy-four patients completed both questionnaires. Most patients reported advantage in symptom control when using medical cannabis, although their expectations were somewhat higher than the reality experienced. Advantage of using medical cannabis was also found concerning improvement of quality of life. Seventy-five of patients still used medical cannabis once completing the second questionnaire and most of them reported that they would recommend the use of medical cannabis. Conclusion: It can be seen from this study that for many oncology patients the use of medical cannabis may be very helpful. However, the use of cannabis is not free of side effects, as can be seen from the patients’ reports. This has clear implications for oncology nursing practice and may lead to a better understanding of patients using medical cannabis in the future, in terms of its benefit and side effects. 

Since the discovery of glare illuminators, considerable efforts have been devoted to achieving a breakthrough of high light intensity on the order of magnitude. In this paper, we prepared strong flash blinding agents for the first time by using aluminum powder, oxidant, and adhesive as the main materials, and tris-(8-hydroxyquinolinato) aluminum (Al2Q3), triazoindolizine, or nano zinc oxide, etc. as electronic output brightener after mixing and granulation according to the developed formulation. It was discovered that the luminescence intensity was related to the thermal effect of the substance while the brightener only served as an auxiliary brightening effect to achieve energy non-destructive conversion. With the same formula, the luminescence intensities of glaze agents with ADN and potassium perchlorate as oxidants were slightly higher than that of ammonium perchlorate oxidant; the brightening effect of nano-zinc oxide was slightly higher than those of tris-(8-hydroxyquinolinato) aluminum (Al2Q3) and triazoindolizine. The luminescence intensity of the substance with a high thermal effect value was high, but the luminescence time was slightly short. Under identical conditions, the luminescence effect of nano-aluminum powder was obviously better than that of micro-aluminum powder with the highest luminescence intensity of 3.9 × 1010 ~ 1.9 × 1011 cd and the luminescence time of 39 - 48 ms. The effects of shell material and structure and the effect of heat-induced mode on the luminescence intensity were also investigated. The luminescence intensity of the glare agent with a high shell strength was high, but the luminescence time was slightly short. Moreover, the energy level of the brightener is excited under the induction of high temperatures, which leads to a blue shift to promote the chemical reaction of the material in a favorable direction. Finally, the optical radiation of the thermally induced high-temperature combustion system was analyzed from the aspects of thermal effect, combustion temperature, and chemiluminescence effect. A way to improve the optical radiation intensity of a high-temperature combustion system was proposed.

Background: Communication is the process of exchanging information or messages from one group to the other through mutually understood verbal or non-verbal ways. Communication barrier is anything that prevents receiving and understanding the messages. poor communication between patients and the nurses’ result in an increased length of stay, wastage of the resource, patient dissatisfaction, absence of confidence, and frustration for both the nurses and the patients. This study will provide basic information on the level of nurses to patients’ communication and perceived barriers in government hospitals of Bahir Dar city. Objective: The objective of this study was to assess the level of the nurse to patient communication and perceived barriers in government hospital of Bahir Dar city, Ethiopia, 2020. Methods: Institution based cross-sectional mixed-methods study was conducted from February 24 – March 9/2020 in government hospitals of Bahir Dar city. A total of 380 nurses were included in the quantitative study by using simple random sampling. For both the quantitative and qualitative study, at the initial stage of data collection and interview; informed consent was obtained from respondents. Data were entered into Epi Data 4.6 and analyzed with a statistical package of social science version 25. Data were mainly analyzed using descriptive statistics and binary logistic regression. For the qualitative study, purposive sampling technique was employed, and 7 participants were interviewed. Thematic analysis was used. Results: From the total participants 36.5% of nurses were found to have poor communication. Variables which have statistically significant associations with the level of communication were educational level, work experience, the unwillingness of nurses, and lack of communication skill. The highest perceived communication barriers were lack of continuous training with 82.7% followed by workload with 80.7% and lack of medical facilities with 79.2% as reported by nurses. All environmental-related barriers were the perceived barriers of the nurse to patient communication. Conclusion: In this study, the communication of nurses to patients is found to low. To enhance communication with the patients; nurses and other stakeholders like the ministry of health, the health bureau, and hospital authorities need to recognize the communication barriers. Giving awareness on the communication barrier for the nurses helps to minimize the barriers and improve the nurses to patients’ communication.

The paper is dedicated to the consideration of the metal-carbon mesocomposites application possibilities for the medicine magnetic transport. This trend is determined by correspondent peculiarities of content and structure of mesoscopic composites. The main peculiarities of these nanosized particles are the following: a) the presence of unpaired electrons on the carbon shell; b) the structure of carbon shell from poly acetylene and carbine fragments; c) the atomic magnetic moment of inner metal is equaled to more than 1–3 μB. The creation of reactive mesoscopic materials with regulated magnetic characteristics which can find application as medicine magnetic transport within an organism is very topical. The present investigation has fundamental character. It’s based on the ideas concerning to the change of metal-carbon mesocomposites reactivity. The use is possible as metal-carbon mesocomposites both and they are modified analogously.

When a stock price rises or has a better P/E ratio, this is generally considered a measure of success. Is this true for health insurance stocks? Stock holders certainly are happy, but what about the purchasers of the carriers’ policies? Are patients smiling when the stock price goes up? 

Introduction: There is increasing published evidence confirming the long-term adult mental and physical health impact of childhood exposure to adverse events including different forms of abuse and family dysfunction. Looked-after Children and young people (LACYP) living in public care are known to be a highly vulnerable group, who have often experienced several pre-care poor socio-economic and family circumstances with subsequent placement instability, as well as inadequate compensatory care within the social care system. We aimed to evaluate the relationship between the adverse socio-emotional risk factors experienced by a cohort of LACYP and their emotional, behavioural and physical health needs within a South-West England Local Authority between Jan and Dec 2018. Methods: We carried out a retrospective review of the medical records of all looked-after children and young people (LACYP) within one year (Jan to Dec 2018) at the North Somerset Local Authority (NSLA). This was an audit project of the LAC Health team completed as part of the Clinical Governance strategies of the NSLA. Results: 93% (89/96) of the LACYP experienced at least one or more socio-emotional adverse risk factors. The commonest socio-emotional risk factors recorded were parent-related including poor mental health (67%), neglectful parenting (59%), drugs/alcohol abuse (45%) and domestic violence (47%). Forty-six (48%) of the LACYP had at least one or more emotional problems, 48 (50%) had neurodevelopmental conditions, while 63 (66%) had at least one or more physical problems. The most common emotional needs were behavioural problems (35%), anxiety/ depression (17%), nicotine/substance misuse (10%) and self-harm (6%). Conclusion: High levels of physical, emotional, behavioral, developmental and neurodisability disorders are prevalent among LACYP due to their high vulnerabilities to adverse life experiences and trauma while living within their biological families. Present and future clinical implications of the socio-emotional risk factors and the need for more integrated multi-agency services for addressing the diverse health needs of the LACYP were discussed. What is known? • There is increasing awareness of the relationship between childhood exposure to adverse events and long-term adult mental and physical health • Looked after children and young people (LACYP) are highly vulnerable to early traumatic and poor socio-economic circumstances exposure What this study adds: • Over 90% of LACYP experienced at least one ACE which disproportionately affected the youngest age-group • Parental factors such as childhood abuse, alcohol/substance abuse and mental health problems were the most common adverse factors experienced by the LACYP

This paper is a study of nuclear reactions involving 12c + 12c nuclei carried out with a heavy-ion nucleus-nucleus optical potential derived from a new M3Y-type effective interaction, called B3Y-Fetal, within the framework of optical model at the incident energies of 112, 126.7, 240, 300, 1016 MeV. Folding analyses of the differential cross sections associated with the elastic scattering of the nuclear system, determined at these incident energies with four B3Y-Fetal-based folded potentials constructed from double folding model, have shown the DDB3Y1- and BDB3Y1-Fetal potentials to be the best in excellent agreement with previous work done with the M3Y-Reid. The agreement of the B3Y-Fetal with the famous M3Y-Reid effective interaction, which is also used for folding analysis in this work, is further buttressed and well-established by the findings of this study Herein, the values of the renormalization factor, NR ranging from 1.1117 to 0.8121, obtained with the B3Y-Fetal have been found to be slightly higher, with lower reaction cross sections, aR = 1418 - 1047 millibarns, than NR = 0.9971 - 0.8108 obtained with the M3Y-Reid effective interaction whose accompanying reaction cross sections, being higher, range from 1431 to 1050 millibarns. This depicts the B3Y-Fetal as having a better performance. Additionally, results of folding analyses have shown the best-fit folded potentials, DDB3Y1- and BDB3Y1-Fetal potentials to be in agreement at all incident energies, implying that the cold nuclear matter has an underlying soft equation of state.
