Published: October 2019

AbstractFaster food freezing rate can be achieved with a lower cold medium velocity at a lower temperature in the cryogenic freezer. In this paper, the Plank method and the computational fluid dynamics method were adopted to analyze the freezing time and freezing rate of golden pomfrets, respectively. To further increase the freezing rate, samples were precooled in the refrigerator (5°C) or the slurry ice (0°C) before freezing in the cryogenic freezer. The result indicates that the freezing rate of the sample is significantly increased after precooling in the slurry ice. And for the same high freezing rate, the result of the quality testing shows there will be a better frozen quality under a lower cold medium velocity at a lower temperature. In conclusion, precooling in the slurry ice (0°C) and freezing with cold medium of 1.7 m/s at −100°C successively is the most efficient method for maintaining the quality of the frozen golden pomfret.Practical ApplicationsFreezing food with a high freezing rate can realize the shelf‐life extension and long‐term preservation. However, there is little research on how to obtain a better quality of the frozen food at the same freezing rate, namely freezing with a lower cold medium velocity at a lower temperature or with a higher cold medium velocity at a higher temperature. This research demonstrates that the former method is preferable. The result shows that precooling in the slurry ice (0°C) and freezing with cold medium of 1.7 m/s at −100°C successively can significantly increase the freezing rate, which is the most efficient method to improve the frozen quality of the golden pomfret. This process can be well applied in the fast food freezing industry.
The hidden edifice of (food) sovereignty: Rights, territory, and the struggle for agrarian reform in Venezuela
Authors: Lubbock Rowan 
Published: October 2019

AbstractThis article seeks to make a critical contribution to the “sovereignty problem” in food sovereignty (FS) studies. Contemporary scholarship has largely struggled to answer the question of who or what is sovereign within the realm of FS politics—underpinned by the relocalisation of agrarian production, sustainable nature–society relations, and a radical democratisation of food systems. Although the most recent scholarship has made significant progress on this issue, I offer an alternative historical materialist account of sovereignty understood as the combination of rights and territory. From a critical Marxian perspective, I deconstruct the basis of sovereign power as the intersection between social property rights (exploitation) and territorial governance (political technology) congealed within both capital and the state. This approach thus provides some clarity as to the necessary breaks required to establish an FS regime (self‐directed labour and cooperative territorial governance). The framework is then applied to the case of Bolivarian Venezuela. While witnessing some important achievements, Venezuela's FS experiment has encountered a number of contradictions. As this case study shows, peasant struggles aiming to retake control over production and establish cooperative forms of governance must traverse the entire terrain of the state and thus affect a broader socialisation of society's sociopolitical infrastructures.

AbstractBackgroundPulsed diode array laser systems are utilized extensively for various aesthetic indications such as removal of unwanted hair, treatment of vascular and pigmented lesions, and wrinkle reduction.ObjectiveThe purpose of this study was to report and assess the experience of using a diode laser system delivering pulsed infrared laser light at the near‐infrared (NIR) spectrum at wavelengths of 805 and 1060 nm.MethodsThe study was a retrospective analysis of treatment outcomes in adult subjects treated at the clinic between January 2017 and April 2018 for wrinkles and pigmentation with a noninvasive aesthetic diode laser system. Subjects were treated at nominal wavelengths of 805 nm for pigmentation and 1060 nm for wrinkles reduction. Improvement in pigmentation and wrinkles, adverse events, and patient tolerability to treatment and satisfaction were evaluated.ResultsOf 44 subjects with Fitzpatrick skin types II‐IV, eight were treated for pigmentation and 36 for wrinkles. For both treatments, subjects reported tolerable pain levels. All immediate responses resolved within 48 hours post‐treatment. Evaluation of treatment outcomes by two blinded evaluators demonstrated significant pigmentation clearance mean of 2.50 ± 0.15, (P < .05) in subjects treated for pigmentation, as well as significant improvement mean of 0.46 ± 0.12 (P = .005) in wrinkles in 13 subjects (41%) whose “before” and “after treatment” photographs were correctly identified by both blinded evaluators. Subjects were satisfied with the treatments.ConclusionsUse of the Diode laser effectively resulted in improvement in pigmentation and wrinkles, while maintaining a high safety profile with limited downtime.
The Unrealized Eschatology of Michel Henry: Theological Gestures from his Phenomenological Aesthetics
Authors: Rios Christopher C. 
Published: October 2019

AbstractThis study responds to readings of Michel Henry’s eschatology as over‐realized through an analysis of his frequently neglected phenomenological aesthetics in Seeing the Invisible: On Kandinsky in light of the theological articulation of his phenomenology of life. It argues for a distinctly unrealized thrust to his program by foregrounding the notion of monumental art and the rootedness of human praxis, artistic and otherwise, in concrete sensible reality. The conclusion suggests that Henry’s project, while theologically problematic, opens a path towards the development of a theological phenomenological cosmology when supplemented.

AbstractCell‐mediated immunity to CMV, if known, could improve antiviral drug therapy in at‐risk children and young adults with LT and IT. Host immunity has been measured with CMV‐specific T cells, which express IFNγ, but not those which express CD154, a possible substitute for IFNγ. CMV‐specific CD154+ T cells and their subsets were measured with flow cytometry after stimulating PBL from recipient blood samples with an overlapping peptide mix of CMV‐pp65 antigen for up to 6 hours. CMV‐specific CD154+ T cells co‐expressed IFNγ in PBL from three healthy adults and averaged 3.8% (95% CI 3.2%‐4.4%) in 40 healthy adults. CMV‐specific T cells were significantly lower in 19 CMV DNAemic LT or IT recipients, compared with 126 non‐DNAemic recipients, 1.3% (95% CI 0.8‐1.7) vs 4.1 (95% CI 3.6‐4.6,P < .001). All T‐cell subsets demonstrated similar between‐group differences. In logistic regression analysis of 46 training set samples, 12 with DNAemia, all obtained between days 0 and 60 from transplant, CMV‐specific T‐cell frequencies ≥1.7% predicted freedom from DNAemia with NPV of 93%. Sensitivity, specificity, and PPV were 83%, 74%, and 53%, respectively. Test performance was replicated in 99 validation samples. In 32 of 46 training set samples, all from seronegative recipients, one of 19 recipients with CMV‐specific T‐cell frequencies ≥1.7% experienced DNAemia, compared with 8 of 13 recipients with frequencies <1.7% (P = .001). CMV‐specific CD154+ T cells are associated with freedom from DNAemia after LT and IT. Among seronegative recipients, CMV‐specific T cells may protect against the development of CMV DNAemia.
Becoming unique: A qualitative study of identity development of adolescent kidney recipients

Published: October 2019

AbstractTeenagers who receive a renal organ transplant have to take up the double challenge of identity development, the primary task of adolescence, and of overcoming the complexities of their illness. Previous qualitative studies found that adolescents felt that the organ transplant and its treatments mainly defined who they are. The relationship to the donor can be a source of concern for some of them, especially for those who received from a parent and feel an obligation to be obedient and grateful. While donor parents are known to interpret their gesture as giving life for a second time, no research to date has described how this particular gesture may influence adolescent development. The present article aims to examine and describe identity development of teenage kidney recipients in a context of parental or deceased donation. We used a qualitative design involving individual interviews with 10 adolescents. Five of them received from a donor parent, five from a deceased donor. Data were analyzed using IPA. Results suggest that identity development is influenced by similar concerns for all adolescents regardless of donor source: body image, social relationships, and anxiety about the future. One aspect that stood out from the discourse of those who received from a parent was feelings of guilt towards the donor when engaging in behaviors that could comprise graft survival, which was a challenge for identity development. Receiving the transplant freed teens from the struggle of just managing their illness and was a catalyst for exploration and engagement, which are crucial for identity development.
Self‐rated health in mothers of children hospitalised for severe illnesses and mothers of healthy children: cross‐sectional study

Published: October 2019

IntroductionSelf‐rated health (SRH) is a recognised tool for predicting morbidity and mortality.AimThe aim of the study was to investigate and compare SRH in a group of mothers of hospitalised children and mothers of healthy children and to indicate the variables associated with poor SRH in both groups.MethodsWe conducted questionnaire‐based cross‐sectional research in a group of 184 women. Half of the respondents (n = 92) were the mothers of children hospitalised for a severe illnesses (Group H). The control group (n = 92) comprised mothers of healthy children (Group C). Self‐Rated Health (SRH), Numerical Rating Scale (NRS), Hospital Anxiety and Depression Scale (HADS), Impact of Event Scale‐Revised (IES‐R) and Interpersonal Support Evaluation List (ISEL‐40 v. GP) were used. In order to facilitate critical appraisal and interpretation of results, STROBE recommendations were used.ResultsThe prevalence of poor SRH was greater in mothers of children hospitalised for a severe illness than in those of healthy children (35 and 19%, respectively). In both groups, the risk of poor SRH was statistically significantly higher in those mothers who for the past 7 days reported at least moderate pain and in mothers who manifested anxiety symptoms. In both groups, the prevalence of poor SRH was statistically significantly lower if the respondents' children were in good health. The risk of poor SRH was associated with poor financial status in group H and with depression and at least moderate pain for the past 7 days in group C.Relevance to clinical practiceIn order to provide mothers of severely ill children with high‐quality health care including preventive measures, it is recommended that their health is assessed by healthcare professionals.

The intervention group comprised 28 (n = 28) adolescents from a school, and the control group comprised 30 (n = 30) adolescents from another school. Solution‐focused interviews, which included educational information regarding leading a healthy lifestyle as well as cognitive–behavioural interview, were conducted with the adolescents of the intervention group, 1 day per week (nine sessions in total).ResultsIn comparison to the control group, adolescents in the intervention group exhibited differences in all the sub‐dimensions health promotion scale (p < 0.001).ConclusionsThese results established the applicability and effectiveness of the programme, such that the health promotion programme could be included in the literature. Moreover, it is anticipated that this programme would be applied in school settings in the future.
Linear hypothesis testing for weighted functional data with applications
Authors: Smaga Łukasz , Zhang Jin‐Ting 
Published: October 2019

AbstractIn socioeconomic areas, functional observations may be collected with weights, called weighted functional data. In this paper, we deal with a general linear hypothesis testing (GLHT) problem in the framework of functional analysis of variance with weighted functional data. With weights taken into account, we obtain unbiased and consistent estimators of the group mean and covariance functions. For the GLHT problem, we obtain a pointwise F‐test statistic and build two global tests, respectively, via integrating the pointwise F‐test statistic or taking its supremum over an interval of interest. The asymptotic distributions of test statistics under the null and some local alternatives are derived. Methods for approximating their null distributions are discussed. An application of the proposed methods to density function data is also presented. Intensive simulation studies and two real data examples show that the proposed tests outperform the existing competitors substantially in terms of size control and power.
The null hypothesis of (common) jumps in case of irregular and asynchronous observations
Authors: Martin Ole , Vetter Mathias 
Published: October 2019

AbstractThis paper proposes novel tests for the absence of jumps in a univariate semimartingale and for the absence of common jumps in a bivariate semimartingale. Our methods rely on ratio statistics of power variations based on irregular observations, sampled at different frequencies. We develop central limit theorems for the statistics under the respective null hypotheses and apply bootstrap procedures to assess the limiting distributions. Furthermore, we define corrected statistics to improve the finite sample performance. Simulations show that the test based on our corrected statistic yields good results and even outperforms existing tests in the case of regular observations.

Published: October 2019

This work is to test the hypothesis of sustainable economic development by using a linear structural model. The structural equations in the structural model show that, the social development goals depend on economic growth and environmental protection goals, namely (Social target) = 1.22 * (Economic target) - 0.064 * (Environment target) and economic development target depend on social development goals and environmental protection goals, namely (Economy target) = 1.35 * (Social target) - 0.039 * (Environment target). The result show that both economic and social development have an adverse environmental impact that will no longer harmonize goals, reflecting the unsustainable marine economic development in the period of 2011-2018. There have many factors of unsustainable marine economic development in period 2011-2018, but mainly is low economic growth efficiency, low labor productivity and the process of urbanization does not truly create a foundation for economic development.
Characteristic Parameters Estimation of Active Magnetic Bearings in a Coupled Rotor System
Authors: Kuppa Sampath Kumar , Lal Mohit 
Published: October 2019

Abstract
Present research inspects the performance of rotor–bearing–coupling system in the presence of active magnetic bearings (AMBs). A methodology is suggested to quantify various fault characteristics along with AMB characteristic parameters of a coupled turbine generator system. A simplest possible turbogenerator system is modeled to analyze coupling misalignment. Conventional methodology to estimate dynamic system parameters based on forced response information is not enough for AMB-integrated rotor system because it requires current information along with displacement information. The controlling current of AMB is tuned and controlled with a controller of proportional–integral–derivative (PID) type. A numerical technique (Lagrange's equation) is applied to get equations of motion (EOM). Runge–Kutta technique is used to obtain EOM to acquire the time domain responses. The fast Fourier transformation (FFT) is applied on obtained responses to acquire responses in the frequency domain, and full spectrum technique is applied to propose the methodology. A methodology that depends on the least squares regression approach is proposed to evaluate the multifault parameters of AMB-integrated rotor system. The robustness of the algorithm is checked against various levels of noise and modeling error and observed efficient. An appreciable reduction in misalignment forces and moments is observed by using AMBs.

AbstractBreast cancer is the most prevalent form of cancer in women with over 266,000 new cases diagnosed every year in the United States. The various methods used for breast cancer screening range in accuracy and cost; however, there is no easily reproducible, reliable, low-cost, nonradiative screening modality currently available, especially for dense breast tissue. Steady-state infrared imaging (IRI) is promising in this area as it is unaffected by tissue density and has the potential to detect tumors by measuring and capturing the thermal profile on the breast surface induced by increased blood perfusion and metabolic activity associated with the tumor. In our proposed clinical IRI and simulation approach (CIRIS™), women with biopsy-proven breast cancer are imaged with IRI in the prone position. The prone position is able to provide a thermal profile of the entire breast without any gravitational deformation or thermal abnormalities in the inframammary fold. A digital model, created using clinical images, is thermally simulated through a commercially available software using known tumor characteristics obtained from the available magnetic resonance imaging (MRI) data. The resulting surface thermal profile is compared with the IRI images. In the three cases discussed here, the digital model was able to accurately predict the breast surface temperature distribution, showing the promise of this approach in breast cancer screening. This preliminary work is expected to lead the way for a larger clinical study in the future to establish IRI as an adjunctive screening technique.
Moulting pattern and mortality during the final emergence of the Coromandel Marsh Dart Damselfly Ceriagrion coromandelianum (Zygoptera: Coenagrionidae) in central India
Authors: Thaokar Nilesh R. , Verma Payal R. , Andrew Raymond J.

The final emergence of the Coromandel Marsh Dart Damselfly Ceriagrion coromandelianum was studied for 50 days (22 January–12 March, 2011) from the botanical garden of Hislop College, Nagpur, India, (a semi controlled site) where small underground cement tubs/tanks are used to grow macrophytes by the Botany department. In C. coromandelianum emergence is asynchronous, diurnal and occurs between 07.00h and 18.00h. Stage-I starts when the ultimate instar nymph of C. coromandelianum leaves the water body, searches for a suitable place and then begins to shudder its body to detach the trapped pharate from the nymphal exuvia. The pharate exerts pressure on the thoracic tergites to split the cuticle. Stage-II starts when the head and thorax of the pharate emerges out of the split exuvia. The pharate struggles to remove its trapped body from the nymphal exuvia. During Stage-III, the wings expand but are opaque; pigmentation of the body occurs simultaneously all over the body. Soon the whole body develops its species specific coloration while the expanding wings gain transparency, unfold and separate out and now the imago is ready for its maiden flight. Stages I, II, and III occupy 31.66%, 11.73%, and 56.60% of the total moulting period, respectively. A total of 243 emergences occurred during the observation period, 158 emergences occurred in tanks containing Pistia stratiotes, while 65 emergences in tubs containing Nymphaea nouchali indicating that C. coromandelianum prefers P. stratiotes over N. nouchali for oviposition. Twenty deaths were recorded during the present observation. Failure to moult (15%) and failure to emerge completely out of the exuvia (85%) were the two reasons for mortality.
