'Caring beyond capacity' during the coronavirus pandemic: the experiences of family caregivers of people with dementia from the IDEAL cohort
Authors: Stapley Sally , Pentecost Claire , Collins Rachel , Quinn Catherine , Dawson Eleanor , Thom Jeanette , Clare Linda
Published: March 2022

Some carers of people with dementia have reported increased caring demands and carer stress during the COVID-19 pandemic. Carers’ experiences during this time may also have implications for resilience. As part of the INCLUDE component of the IDEAL cohort study, the overall aim of this subtle realist qualitative study was to explore family carer experiences of caring for someone with dementia one year into the COVID-19 pandemic in England, and to consider the study findings in relation to resilience frameworks in dementia caregiving. Seven family carers of people living with mild-to-moderate dementia were interviewed, and themes derived using framework analysis. Themes described the complex challenges of caring during the pandemic, with interviewees burned out and ‘caring beyond capacity’ due to unmet needs within the caring role and caring in isolation from family and professional support. Findings provide evidence that trait resilience approaches fail to account for important aspects of carers’ experiences, highlighting the range of contextual factors which influence experiences of the caregiving role, lending support to transactional resilience frameworks. More importantly than building individual resilience, timely practical support for carers is essential to protect their well-being and to ward against the potential consequences of carer burnout.
Compositing of coffee silverskin with carbon rich materials leads to high quality soil amendments
Authors: Picca Giuseppe , Plaza César , Madejón Engracia , Panettieri Marco
Published: March 2022

Purpose: Coffee silverskin (CS) is the integument covering the raw coffee bean, representing the primary waste product of the coffee-roasting industry. Despite the growing attention in seeking potential reuse of this material, the majority of CS is commonly used as a firelighter or discharged to landfills. The study aimed to test co-composting as a low-cost solution that meets the circular economy paradigms proposed by the European Union.Methods: Four composting mixtures were prepared mixing CS with pruning waste and biochar at different ratios, aiming to maximize the amount of compostable CS per batch and monitored for 60 days.Results: The contents of macro-, micro- and trace elements of the final composts matched the strictest requirements of the Spanish national regulation on compost quality (Class A amendments), proving that CS composts area high-value amendment rich in N and K. Despite the highly phytotoxic effect of CS raw material, the seed germination tests showed that all the mature composts exhibited phytostimulant properties allowing their harmless application to the soil.The four composts had a high water holding capacity (237 - 351 % dw) and they are likely to promote the persistence of plant-available water in the soil.Conclusion: The present study showed that composting the whole CS produced in Europe would lead to a recovery of 2,420 to 3,481 tons of nitrogen and 1,873 tons of potassium, reducing the dependency on mineral fertilizers, thus meeting the growing demand for sustainable and low-cost amendments.Statement of noveltyCoffee silverskin is the protective layer of the coffee beans, the main by-product of coffee roasting process that largely accumulates in consuming countries. Despite its high content in nitrogen and potassium, and its extremely high water retention capacity, the presence of phytotoxic compounds limited the use of coffee silverskin as soil amendment.In this study we demonstrate that co-composting with carbon rich materials, such as gardening prune and biochar, is a valid alternative to remove the phytotoxicity effect of raw coffee silverskin maintaining its beneficious agronomical properties.Composting coffee silverskin appears to be an easy process and a low-cost opportunity: up to 3,481 tons of N and 1,873 tons of K could be recovered in Europe from this by-product.

In this article we study the squeezing and statistical properties ofthe light producedby a non-degenerate three-level laser, with the parametric amplifier .With the aid of the master equation, we obtain stochasticdifferential equations. Applying the solutions of the resultingdifferential equations, we calculate the quadrature variance,themean and variance of the photon number ,the photon numbercorrelation . However, thetwo-mode driving light has no effect on the squeezing properties ofthe cavity modes. On the other hand, the parametric amplifier andthe thermal reservoir increase the mean and the variance of thephoton number. Furthermore, employing the same solutions, we alsoobtain the anti normally ordered characteristic function defined inthe Heisenberg picture.

The demand analysis method of maritime emergency resources is the key technology to promote a reasonable emergency resource allocation during maritime emergency management. It is widely used to improve the efficiency of maritime emergency rescue and reduce the loss of maritime accidents. However, it requires a scientific and effective method of the demand analysis of maritime emergency resources. This paper aims to analyze the underlying modeling paradigms and to assess the extent to which the demand analysis methods of maritime emergency resources can meet the requirements. Focusing on the demand analysis methods, this paper provides a broad overview of the current literature on maritime emergency resources of the last decades, by considering the models’ purposes, theoretical frameworks, factors, and outputs. The results indicate that the existing methods can be classified into three concepts: the linear regression theory, Back Propagation (BP) Neural Network, and Case-based Reasoning (CBR) technology. Combined with the characteristics of China's maritime emergency management field, the interaction between theoretical framework and applications is not sufficiently understood and thus needs to be further studied. Being familiar with knowledge gaps acts as a catalyst for further research on scientific and efficient demand analysis methods of maritime emergency resources in various navigation conditions.
Resetting of the U-Pb and Th-Pb systems in altered bastnäsite: Insight from the behavior of Pb at nanoscale
Authors: Zhang Wei , Chen Wei Terry , Harlov Daniel , Gao Jian-Feng
Published: March 2022

Bastnäsite contains considerable amounts of U and Th and has been widely used for U-Th-Pb dating. Hydrothermal alteration of bastnäsite is common in nature but its effects on U-Th-Pb dating are not currently well constrained. Hence the significance of U-Th-Pb ages obtained from altered bastnäsite cannot be evaluated. Here, we present a detailed geochronologic as well as micro- and nano-scale mineralogical study of altered bastnäsite in a Mo-REE deposit, Central China. The original bastnäsite grains were confirmed to have crystalized at 208 Ma but were variably overprinted by a hydrothermal event at 150 Ma. They commonly exhibit typical replacement textures that appear to have formed from a coupled dissolution-reprecipitation process, i.e., a primary unaltered domain surrounded by a porous altered domain. Micro- and nano-scale mineralogical observations strongly suggest that during the coupled dissolution-reprecipitation process, non-radiogenic (common) Pb was incorporated into the altered domains in the form of nanoscale galena inclusions. Such incorporation (even minor) has significantly affected the 206Pb/238U and 207Pb/206Pb ratios due to the low contents of U and its daughter isotopes in bastnäsite, resulting in highly variable, discordant U-Pb dates for the altered domains. In contrast, incorporation of the non-radiogenic Pb has very limited effects (<5%) on the Th-Pb system due to the remarkably high contents of Th and radiogenic 208Pb in bastnäsite. Instead, the scattered 208Pb/232Th ages (208 to 150 Ma) of the altered domains were essentially affected by incomplete replacement, and thus can be used to approximate the lower age limit of the primary hydrothermal activity or the upper age limit of the secondary hydrothermal activity. The results from this study highlight that because of the different orders of magnitude between the U and Th contents in bastnäsite, the mobilization of radiogenic and non-radiogenic Pb during alteration may have significantly different impacts on the U-Pb and Th-Pb systems. Therefore, the two systems should be treated separately during the dating of bastnäsite resulting from secondary hydrothermal events.

Uterine myomas are present in 20 to 50% of women of childbearing age and are the most common benign tumor. The discovery of a myoma in a pregnant patient is a frequent situation. Fibroids can complicate the course of pregnancy and childbirth. The benefit/risk balance between expectation and management of fibroids must therefore be weighed by the practitioner. During pregnancy, surgical management is possible but should be reserved for limited indications. We report a case of myomectomy on pregnancy of 22 SA for a huge fibroid in cystic degeneration at the Suissi maternity hospital in Rabat.

Fasting during Ramadan is a major challenge for diabetics because of its various risks. A therapeutic management plan can ensure fasting while minimizing the associated risks. Our aim was to implement a pre-Ramadan management program and to define patient profiles that are more adapted to fast. Methods: 262 type 2 diabetic patients were recruited from both 2019 and 2021 Ramadan campaigns organized at the endocrinology department of the Mohammed VI University Hospital of Marrakech, excluding pregnant women and patients with chronic end-stage kidney disease. Results: Predominantly female and aged between 50 and 70 years, with a high BMI. Glycemic control was close to target for fasters. The most common comorbidities in our series were hypertension and dyslipidemia. 19.8% of our patients had an associated cardiovascular complication and 10.5% had kidney disease. After stratification, the non fasting decision concerned most of our diabetics in 2021 compared to 2019. Conclusion: A therapeutic management plan help to fit guidelines. Compared to 2017, the updated 2021 stratification guidelines are more comprehensive and have defined more non fasters patients.

Regenerative endodontics has been defined as biologically based procedures designed to replace damaged structures, including dentin and root structures, as well as cells of the pulp-dentin complex. Presently, two concepts exist in regenerative endodontics to treat non-vital infected teeth - one is the active pursuit of pulp-dentine regeneration to implant or regrow pulp (tissue engineering technology), and the other in which new living tissue is expected to form from the tissue present in the teeth itself, allowing continued root development(revascularisation). Regenerative endodontic procedures (REPs) have evolved in the past decade, being incorporated into endodontic practice and becoming a viable treatment alternative for immature teeth. The authors have summarized the status of regenerative endodontics on the basis of the available published studies and provide insight into the different levels of clinical outcomes expected from these procedures.

Introduction: Haemoglobin is the red colour pigment present inside RBC. All the blood components are derived from the haematopoietic stem cells of the same bone marrow. Factors affecting the bone marrow also affects all the cells including the haemoglobin level and the platelet count. Less is known on the relationship between low or high level of haemoglobin on platelet count. This work was therefore carried out to determine this relationship. Materials And Methods: The study was done in Dept. of Physiology, Jorhat Medical College. Study population included 100 undergraduate medical students of age 18-25 years . Haemoglobin Estimation & Platelet Count will be measured by ACCUREX ACCULAB CBC 360+ HEMATOLOGY Analyser Machine. Ethical Clearance was obtained from Institutional Ethical Committee (H), Jorhat Medical College, Jorhat. Students unpaired t- test was used to compare the mean values of study variables and other parameters in relation to the study. The P value <0.05 was considered as significant. Results: We found that mean Hb count is 10.91Â±1.05 and 10.22Â±0.83 respectively when platelet count in between 1.5- 2.5 lakhs/mm3 and >2.5 lakhs/mm3. Mean Platelet count came 2.59Â±0.58 lakhs/mm3 and 1.89Â±0.62 respectively when Hb between 9 â€“ 11 gm/dl and >11 gm/dl. Conclusion: The reason for the relationship between low and high platelet count on hemoglobin level may be linked to the normal physiology of hematopoiesis where the origin of all blood components occurs in the bone marrow. This leaves scope for further research to use in therapy like Plateletpheresis where lower hemoglobin concentrations meant higher platelet yield and vice versa.

Patients and Methods: We carried out a retrospective analysis of types and causes of 40 children up to the age of 14 years with ENT injuries managed in the department in the period from March 2019 to April 2021. Results: The total number of patients was 40 and it comprised of 31 males (77.5%) and 9 females (22.5%). Twelve (30%) of the children were under the age of 5 years, 14(35%) were 6-10 years of age and 14 (35%) in the age group of 11â€“14 years. The most common injury was nasal bone fracture (28.45%) The lacerated soft palate was the second common injury which account for (22.5 percent). The most prevalent site of injury was the nose region. About 32.5 percent of the injuries were caused by falls and accidents, which included falling from roof, trees, beds or cribs, and falls while sporting. About 35% of all injuries are caused by pointy items in the mouth and traffic accidents. The falls while playing in addition to injury with pointy materials was observed in patients under the age of five years. Blunt trauma, falls from stairs and during playing, as well as damage with pointed items, were the most common etiological causes in children aged 6â€“10. The ages of 11â€“14 years were shown to be the most vulnerable to falls and traffic accidents. Conclusion: ENT injuries in children differ from those in adults in terms of type and mechanism. Prophylactic measures should be adopted for children who are at risk of ENT injuries.

Resveratrol is a natural polyphenol present in the Japanese knotweed. It exhibits variety of chemopreventive and anti-proliferative effects against the different cancer cell lines. During skin carcinogenesis, the radical scavenging activity gets altered which are important to prevent the deleterious effect of free radicals. The present study targeted to elucidate the anti-cancer potential of resveratrol against the 7, 12-dimethylbenz[a]anthracene induced skin carcinogenesis in swiss albino mice. Intraperitoneal administration of resveratrol (5mg/kg and 10mg/kg of the body weight) revealed a significant reduction (p<0.001) in the tumor incidence, tumor burden and the mean tumor volume as compared to the control group. Also, towards the end of 10 and 22 weeks, resveratrol restored the activities of the antioxidant enzymes significantly in the treated groups. Histopathological studies revealed thickened corrugated and hyper-proliferative epidermis in skin tumor of 7, 12-dimethylbenz[a]anthracene induced mice and the similar results were found to be at significantly lesser extent post resveratrol treatment. The cumulative results of this study indicate that the resveratrol has potentials to modulate the 7, 12-dimethylbenz[a]anthracene induced histopathological and biochemical alterations during skin melanoma in mice.

Published: March 2022

Academic resilience and emotional intelligence are considered important personal resources for furthering students’ academic performance. However, many educational organizations seem to trivialize the performance implications of these constructs in teachings and curriculum. Consequently, it can decrease not just their academic performance but also their employability, as they lack the generic competencies to adapt and survive in a stressful context. Even so, empirical evidence on integrating academic resilience, emotional intelligence, and academic performance remains unexplored in the Nigerian university context. Therefore, the study aimed to investigate the linkages between academic resilience, emotional intelligence, and academic performance in Nigeria. The partial least square (PLS) modeling method was utilized for testing the stated hypotheses with data collected from 179 final year undergraduate students in the regular B.Sc. Business Administration and B.Sc. Marketing program at Delta State University, Nigeria. From the PLS results, the study reported that academic resilience was positively related to emotional intelligence (β = 0.125, p = 0.007), academic resilience (β = 0.231, p = 0.000) and emotional intelligence (β = 0.260, p = 0.000) were positively related to academic performance, and emotional resilience mediated the positive relationship between academic resilience and academic performance (β = 0.057, p = 0.005). While academic resilience predicted academic performance, it also predicted emotional intelligence, which affected academic performance significantly and positively.
Jet flow in hydraulic-jump-stepped spillways: experimental study

A hydraulic-stepped spillway was designed using an aeration basin to provide aerated flow to the stepped spillway utilizing a hydraulic jump. However, the flow through the entrance of the stepped spillway might separate from the first step top and impact the downstream steps at a large unit discharge, causing a so-called jet flow. A new experimental study was conducted to better understand the jet flow in the hydraulic-jump-stepped spillway with comparisons with conventional stepped spillways. The results showed that the critical condition required for the formation of the jet flow was close to the geometric parameters of the upstream aeration basin. Among these parameters, the height of the reverse step had a more significant effect on the local flow pattern, thus lowering the risk of jet flow. The relationships between the critical condition and the geometry of the aeration basin suggested that the Froude number at the entrance of the stepped spillway was the key parameter forming the jet flow. Compared with conventional stepped spillways, the hydraulic-jump-stepped spillway could effectively extend the practical application for large unit discharges by providing a better understanding of jet flow conditions.
Purification of bathing wastewater by double suspended layer fluidized bed reactor
Authors: Ban YunXiao
Published: March 2022

An external radial magnetic field and built-in stainless steel balls formed a magnetic suspended layer (MSL), as observed in this study. Under the condition of crossflow inflow, the flocculating agent and coagulant aids form a flocculated particles suspension layer (FPSL). Thus a double suspended fluidized bed reactor was constructed to treat bathing wastewater. A particle image velocimetry device was used to detect flow patterns and analyze the flocculation conditions. The results showed that under the condition of crossflow inflow, at the same time, the flooding water was 0.023–2.101 m3/h, and the dosage of poly aluminum chloride (PAC) and polyacrylic amide (PAM) was 90 mg/L and 1.5 mg/L, respectively, and removal rates of turbidity, chemical oxygen demand (CODCr) and linear alkylbenzene sulphonates (LAS) reached more than 99, 90, and 80%. Filtration, grid flocculation and particle interception were functions of the MSL. Meanwhile, the crossflow input created additional vortexes, increasing the likelihood of flocculation particle collision, improving the flocculation conditions and cleaning the MSL. The reactor aids in the development of the initial flocculated particles suspension layer, flocculation strengthening, chemical dosage reduction, effluent qualities improvement, and effluent stability maintenance.
Coke-oven wastewater treatment in a dual-chamber microbial fuel cell with thiocyanate-degrading biofilm enriched at the air cathode

Coke-oven wastewater is usually treated with the activated sludge process, which requires large amounts of electrical energy for aeration and sludge disposal. A more sustainable treatment is strongly required. Recently, microbial fuel cells (MFCs) are focused as a technology for the production of electricity from wastewaters with simultaneous removal of organic matter. However, no MFC has been reported that can remove phenol, thiosulfate and thiocyanate simultaneously without aeration. Phenol can generally be removed well, whereas thiocyanate is relatively difficult to degrade. In this study, a dual-chamber MFC (D-MFC) was designed and equipped with a thiocyanate-degrading biofilm enriched on an air cathode. The D-MFC degraded phenol and thiosulfate in the anode chamber at the rate of 104 and 331 mg/L/day, respectively and subsequently degraded thiocyanate in the cathode chamber at the rate of 250 mg/L/day. The D-MFC showed high thiocyanate degradation rate. This suggests that pre-enrichment could accelerate thiocyanate degradation in MFC. In addition, thiocyanate degradation was not inhibited by phenol as thiocyanate was removed in the cathode chamber after phenol was removed in the anode chamber. This study demonstrated the feasibility of treating coke-oven wastewater by a D-MFC with a thiocyanate-degrading biofilm enriched at the air cathode.

Relatively recently, the concept of the unity of the space, biosphere and humans has become a subject matter of serious scientific researches. The concept was put forward by Russian scholars and thinkers among which the seat of honor is occupied by K.E. Tsiolkovsky and A.L. Chizhevsky. Both researchers were concerned in how the space is related to its greatest creation – life and its meaning on the scale of the Universe. Their works were largely devoted to theoretical and experimental studies of these issues. Both of them accepted the broad spread of extraterrestrial life forms and close dependence of the global Earth's eco-system (biosphere) on space effects. Now there is good reason to assert that the ideas of A.L. Chizhevsky and K.E. Tsiolkovsky had a fundamental role in establishment of space biology as a new branch of science.

We undertook analysis of archival diaries from the IBMP isolation studies performed in the time period from 1980 to 1990 with participation of main (MT) and visiting (VT) teams. The purpose was to evaluate how the stay of visiting teams changed the pharyngonasal and intestinal microbiocinoses of main teams exposed to prolonged isolation. According to the analysis, the VT arrival at the time MT acute adaptation unbalanced the pharyngal microbiota of the latter. By the time of the second VT arrival, MT had been adapted well to the chamber environment. At the end of isolation, stability of the pharyngal microflora had been compromised a little and negative changes prevailed; however, there was no reliable difference between MT and VT members. Analysis of the intestinal eubiotic index calculated for MT and VT members showed that MT microflora was more resistant to the isolation stress-factors. Indeed, the eubiotic index was invariably higher in the main teams at all the isolation periods. It is noteworthy that during acute adaptation the intestinal microflora displayed some transitory instability in the MT members. A slight growth of the eubiotic index in VT members suggested a more rapid adjustment to the environmental stresses.

Este documento tiene la finalidad de identificar el nivel de competitividad del sistema turístico de las ciudades catalogadas por el programa federal de apoyos a la cultura como Ciudades Mexicanas Patrimonio Mundial, mediante la metodología del análisis factorial de correspondencias, para, de este modo, darle un trato en diferentes dimensiones y con múltiples variables. Una vez ubicadas las variables de cada factor, en concordancia con el grado de correlación de estas, se procede al análisis en cada una de las ciudades, con lo cual se identifican las dimensiones que explican la competitividad del sistema turístico en estas ciudades y, como resultado, se obtiene el índice de competitividad. Los resultados muestran que, en materia de accesibilidad y movilidad, la mayoría de estas ciudades ofrecen opciones muy limitadas, lo que dificulta el acceso y la movilidad con los mercados actuales y potenciales.
Cambio, élite y reclutamiento político en el estado de Veracruz Javier Duarte Ochoa y el fin de la hegemonía del Partido Revolucionario Institucional en el gobierno estatal (2010-2016)
Authors: Tahar Chaouch Malik
Published: March 2022

En este artículo se busca analizar las condiciones del fin de la hegemonía priista en el gobierno del Estado de Veracruz desde la perspectiva de las dinámicas de la élite política estatal restringiéndose a la composición del gabinete de Javier Duarte Ochoa (2010-2016). Para ello, el análisis se apoya en el marco teórico-metodológico del reclutamiento político. De este modo, se da cuenta de las trayectorias, características y comportamientos de los individuos y de las facciones que conformaban la élite priista, así como de sus relaciones internas, mediante la problematización de la relación entre la política estatal y la nacional. En consecuencia, este artículo responde a la carencia de estudios sobre las élites políticas regionales en México. La principal tesis de este consiste en el rechazo de la oposición binaria entre continuidad y cambio para implicarlos juntos en la crisis de hegemonía que supuso el fin del monopolio del Partido Revolucionario Institucional (PRI) en el gobierno estatal, que incluía a la oposición que se benefició de ello.
