Effect of Topical Lettuce (Lactuca sativa L.) Seed Oil on Childhood Sleep Disorders: a Randomized Double-Blind Controlled Trial

Background and objectivesSleep disorders are among the most common complaints in childhood. Considering the pitfalls regarding safety and efficacy of conventional treatments for sleep disorders in children and based on the Persian medicine literature and results of recent animal and clinical investigations, this study was conducted to evaluate the effect of topical lettuce seed oil in these patients.MethodsThe study was a double-blind randomized controlled trial in 3-6 years old children with sleep disorders. They were randomly assigned to receive either topical placebo oil and clonidine capsule or lettuce seed oil and placebo capsule for three weeks. Lettuce seed oil was prepared using cold press method. Persian version of “BEARS” pediatric sleep questionnaire was used before and after the intervention. Data analysis was performed using SPSS software (version 20) . ResultsAt the end of study, 67 patients out of 72 completed the study. Similar to control group, children in intervention group significantly improved regarding bedtime issues (p<0.001), excessive daytime sleepiness (p=0.003), night awakenings (p=0.008), and problems in regularity and duration of sleep (p<0.001); however, no significant change was observed regarding the snoring in both groups.ConclusionsTopical use of lettuce seed oil on forehead and temporal areas of children could be considered as a safe and effective treatment for sleep disorders. However, further studies with larger sample size, longer duration of follow-up, and with the use of objective outcome measures are warranted.
A genomic and electrophysiological study of photoreception in the eyeless cnidarian Hydra vulgaris

Hydra are tubular coelenterates with two germ layers, the endoderm and ectoderm. A ring of five to eight tentacles surround an oral pore, and the animal attaches to the substrate via adhesion of the peduncle at the opposite end. They possess a complete ectodermal nerve net, with nerve fibers running within the ectoderm throughout the body and along the length of the tentacles (Hufnagel 1976.) Hydra has two nerve rings. One nerve ring surrounds the mouth and is thought to coordinate mouth opening. A second ring, located at the base of the tentacles, coordinates movements of the body, tentacles, mouth, and nematocysts in response to chemical, photic, and tactile stimuli. The functional unit of the tentacle effector systems is the battery cell complex. The battery cell complex consists of a large epithelial cell called a battery cell and its associated complement of neurons and nematocytes. These battery cell complexes link to each other via interdigitating neuronal processes and myonemes. They have been shown to respond to diverse chemical and mechanical stimuli. When separated from the battery cell, the nematocyst is still able to respond to mechanical and photic stimuli, though not chemical cues. Hydra have been known to be photosensitive since the 1800’s, and have been shown to demonstrate a preference for some colors over others. They are sensitive to light at the base of the animal. Exposure to light causes contractions of the endodermal musculature and extensions of the body column. Light exposure also changes the frequency of both ectodermal contraction pulses and endodermal rhythmic pulses. Further, I have found in my current electrophysiological experiments that hydra’s ablated tentacles show some of the same differences in behavior across
Study of preventable causes of blindness in a tertiary care institute in Lucknow

Background: World Health Organization (WHO) in 2019, released the estimates which show that approximately 80% of the causes of blindness and severely reduced visual acuity are preventable and avoidable. The aim of the study was to assess the prevalence of preventable causes of blindness in an OPD setup in the city of Lucknow. Methods: Descriptive cross-sectional study was done from January, 2019 to March, 2019 at the ophthalmology department OPD, Dr Ram Manohar lohia hospital, Lucknow. Patient presenting with complains of Blurring of vision or blindness during the defined OPD days at the study place, sample size- 550. Convenience sampling, all the eligible patients who were attending the OPD on defined days during the study period. Results: The current study found the prevalence of blindness in the OPD based patients to be 13.5% and 25% (WHO and NPCB standards) respectively which is higher than the other reported statistics and found cataract to be the single most contributor of cause of blindness in accordance with other literature. Conclusions: The study demonstrates that even after the implementation of a national program (NPCB), the prevalence of blindness continues to be on the higher side and cataract remains to the most common cause of preventable blindness.
Effect of Nano-MgO Particles Doping on Breakdown Characteristics of Polypropylene

In this article, the nano-MgO particles were used as inorganic fillers, and polypropylene (PP) polymer was used as a matrix. The nano-MgO/PP composites were prepared by double melt blending. Using the polarization microscope (PLM) test and hot-stage microscope test, the crystalline morphology of PP and nano-MgO/PP with different mass fraction were observed. Using the differential scanning calorimetry (DSC) test, the parameters and crystallinity in the process of isothermal crystallization could be obtained. Additionally, the samples of pure PP and nano-MgO/PP composites were dealt with using a breakdown test and a dielectric frequency spectra test. From the experimental results, nano-MgO particle doping decreased the samples’ crystal size, and the crystalline structure was converted from large spherulites to fascicled crystallization. Additionally, the crystallization rate became fast and crystallinity increased. According to the breakdown test, the nano-MgO particle doping made the composites form small, dense spherulites. The breakdown developed through a longer path, so the composites’ breakdown strength rose greatly. When the mass fraction of nano-MgO particles was 3%, the shape parameter of the composites’ Weibull distribution β was larger, which illustrated that the nano-MgO particles were dispersed uniformly in the PP matrix. According to the dielectric frequency spectra test, the dielectric constant of different nanocomposites were all lower than which of pure PP, but the loss angle tangent values were all higher than which of pure PP.
Board independence and CSR reporting: pre and post analysis of JCGC 2009

This study aims to investigate the influence of board independence on the level of corporate social responsibility (CSR) reporting in Jordan over time. The paper also compares this level of influence between the pre- and post-issuance of the Jordanian corporate governance code (JCGC) in 2009. ,Longitudinal data (panel data) from all non-financial listed companies on the Amman stock exchange for the period 2006-2015 was collected and analysed. The content analysis method was used to assess the CSR reporting evident in the annual reports. An ordinary least square regression was used to investigate the relationship between board independence and the level of CSR reporting. ,The results revealed that board independence has a positive and significant influence on the level of CSR reporting. This influence became significantly stronger post the issuance of the corporate governance code in Jordan. The findings suggest that the presence of independent directors on the board encourages companies to report additional CSR information as one of the legitimation strategies to manage the expectations of stakeholder groups. ,This study provides motivation for regulators and companies to continue to improve board independence effectiveness. ,The study supported evidence from prior studies, conducted the developed countries, that legitimacy theory is also applicable in Jordanian companies, which is a developing country. This study contributes to the debate and findings of the literature about governance and CSR reporting, specifically in the Middle East, as well as the potential of future studies in developing countries using a legitimacy theory as the basis for their investigations and motivation. This study provides evidence to motivate regulators and companies to improve, further, board independence effectiveness. ,This empirical study has explored the potential influence of board independence on the level of CSR reporting in Jordan for JCGC pre- and post-issuance, which has not been examined previously and the findings for future studies in the Middle East region and other developing countries.
Reflecting Art in Nursing Practice

Supplemental digital content is available in the text. Despite evidence of its positive impact on observation, description, empathy, and self-care, few arts-related professional development opportunities exist for nurses in practice settings. This academic medical center launched a 4-part visual arts–humanities professional development workshop for RNs to enhance their clinical skills through reflective activities and guided conversations of art. Participating RNs provided written feedback of their impressions and reflections on course content and potential personal growth. Participants reported profound changes in their self-awareness in multiple areas, and 3 consistent themes emerged: 1) seeing as enhanced observation; 2) attunement, and 3) thinking shifts. The workshop also provided respite from patient care demands for professional development and opportunities to cultivate collegial relationships among nurses from different areas and units. These findings underscore the value of the Quadruple Aim, which focuses on workplace practices that promote a sense of well-being and meaning at work. Consistent support from the chief nursing officer and nursing leadership was essential to the success of the program.
Social wellbeing among women living with cancer

Women living with cancer are gradually increases in number due to the increase prevalence of breast and cervical cancer worldwide. The social impact of cancer is underappreciated compared to physical and psychological impacts. This study aimed to: 1) compare and analyze the social wellbeing (SWB) between women living with breast and cervical cancer, and 2) determine the best predictor of SWB in both groups. This cross-sectional study involved 58 and 47 women living wih breast and cervical cancer (n=105). Questionnaire of QOL-CS part III was used in data collection. Various statistical tests were used in data analysis (α<0.05). Sufficient SWB was mostly found in both cases. Family stress, work life, home activities, worriness, social support, personal relation, sexuality, social isolation, and financial burden were significantly different between cases (p=0.021, p=0.027, p=0.004, p=0.022, p=0.000, p=0.000, p=0.000, p=0.000, and p=0.001 respectively), resulted in significant difference in overall SWB between cases (p=0.000). Home activities were the best predictor of SWB in both cases (R2=0.680 and R2=0.840 respectively) with more influences on cervical cancer (84% of influence). SWB was better in women living with breast cancer.
Sulfided NiMo/Clinoptilolite Catalysts for Selective Sulfur Removal from Naphtha Stream without Olefin Hydrogenation

The natural clinoptilolite zeolite has been modified by acid leaching with HNO3 in order to obtain economic material for supporting NiMoS hydrotreating catalysts. The most optimized zeolite material was obtained by leaching with HNO3 at 80°C during 24 h. The bimetallic NiMo catalysts prepared by wet impregnation of a zeolite support, followed by calcination and sulfidation, were characterized by several physico-chemical techniques and tested in the hydrodesulfurization (HDS) of 3-methyl-thiophene (3-MT) model feed at atmospheric H2 pressure and T = 280°C. For all catalysts, the 3-MT transformation mainly occurs via direct desulfurization reaction route being diminished the catalyst hydrogenation function. This was linked with the formation of highly stacked layers of MoS2 particles having a low amount of “brim sites,” as demonstrated by HRTEM. The cause of the best performance of Ni-Mo(H)/Z-1 sulfide catalyst in the HDS of 3-MT can be the presence of K impurities on the support surface which forces the formation of highly stacked layers of MoS2 particles.
Online Worker Fraud and Evolving Threats to the Integrity of MTurk Data: A Discussion of Virtual Private Servers and the Limitations of IP-Based Screening Procedures

We identify a pervasive, yet previously undocumented threat to the reliability of MTurk data—and discuss how this issue is symptomatic of opportunities and incentives that facilitate fraudulent behavior within online recruitment platforms. In doing so, we explain how IP addresses were never intended to identify individuals and are likely insufficient to identify and mitigate emergent risks around data integrity. We discuss MTurk samples for two studies that include alarming proportions of participants who circumvent an entire set of conventional sample screening methods—and provide disturbingly low-quality responses. These “bad actors” exploited inherent limitations of IP screening procedures by using virtual private servers (VPS) that concealed the IP address of their local devices. While service providers now help target this abuse, the underlying limitations of IP screening procedures remain. Our findings emphasize the importance of continued diligence within the research community to identify and mitigate evolving threats to data integrity.
Unraveling the Ground-State Structure of BaZrO3 by Neutron Scattering Experiments and First-Principles Calculations

The all-inorganic perovskite barium zirconate, BaZrO3, is a widely used material in a range of different technological applications. However, fundamental questions surrounding the crystal structure of BaZrO3, especially in regard to its ground-state structure, remain. While diffraction techniques indicate a cubic structure all the way down to T = 0 K, several first-principles phonon calculation studies based on density functional theory indicate an imaginary (unstable) phonon mode due to the appearance of an antiferrodistortive transition associated with rigid rotations of ZrO6 octahedra. The first-principles calculations are highly sensitive to the choice of exchange-correlation functional and, using six well-established functional approximations, we show that a correct description about the ground-state structure of BaZrO3 requires the use of hybrid functionals. The ground-state structure of BaZrO3 is found to be cubic, which is corroborated by experimental results obtained from neutron powder diffraction, inelastic neutron scattering, and neutron Compton scattering experiments.
Machine learning for forewarning crop diseases.

With the advent of computers, the development of accurate forewarning systems for incidence of crop diseases has been increasingly emphasized. Crop diseases are one of the major causes of reduction in crop yield and hence timely application of remedial measures may combat the yield loss to a great extent. Forewarning systems can help in providing prior knowledge of the time and severity of the outbreak of such diseases. Crop diseases are influenced by interaction of various factors Machine Learning for Forewarning Crop Diseases
Effects of Waxy and Normal Hull-less Barley Flours on Bread-making Properties

Replacement of wheat flour by 10, 20 30% waxy and normal (non-waxy) hull-less barley flour was tested for the effects on bread-making properties. The addition of waxy hull-less barley flour resulted in lower amylograph pasting temperature, peak, and set back viscosities and in higher water absorption, compared with normal hull-less barley flour. Increasing proportions of hull-less barley flour significantly decreased the loaf volume and had deleterious effects on subjective bread scoring. Replacement of 10% of wheat flour by both waxy and normal hull-less barley flour did not significantly affect bread characteristics. However, significant differences in bread quality were observed between the control bread and bread containing more than 20% barley flour, with the normal barley flour showing slightly better scores in organoleptical preference. Textural measurements of crumb firmness showed that the bread containing 20% waxy hull-less barley flour hardened slower during 5-day storage at than bread containing normal hull-lee barley flour.
Development of Digital Learning Media on Entrepreneurship Subject Using Creative Productive Learning Strategies

The form of learning strategies that are considered appropriate is creative-productive (CP). This learning strategy challenges students to produce creative product that comes from their understanding of the concepts being studied. Learning steps include: orientation, exploration, interpretation, and re-creation. In connection with this reality, the researchers felt the need to conduct research and development that focused on efforts to obtain alternative structured patterns by developing digital learning media for "entrepreneurship" subject using CP learning strategies in determining business opportunities in the field of mechanical engineering. The development of digital learning materials uses a research and development (R&D) approach, a process used to develop and validate products. Data collection techniques in validating learning material products are carried out by distributing questionnaires. This study was designed in three stages: (1) Research in the form of planning and formulation of learning objectives, (2) Development in the form of making entrepreneurial learning materials using CP learning strategies, (3) Formative evaluation and revision by material experts, media experts and instructional design experts and evaluators one to one, small group, field trial. With these three stages of research and development, it is expected that the teaching material produced is feasible to be implemented and can improve student competence in determining business opportunities.
Evidence of elevation-specific growth changes of spruce, fir, and beech in European mixed mountain forests during the last three centuries

In Europe, mixed mountain forests, primarily comprised of Norway spruce (Picea abies (L.) Karst. ), silver fir (Abies alba Mill.), and European beech (Fagus sylvatica L.), cover about 10 × 106 ha at elevations between ∼600 and 1600 m a.s. l. These forests provide invaluable ecosystem services. However, the growth of these forests and the competition among their main species are expected to be strongly affected by climate warming. In this study, we analyzed the growth development of spruce, fir, and beech in moist mixed mountain forests in Europe over the last 300 years. Based on tree-ring analyses on long-term observational plots, we found for all three species (i) a nondecelerating, linear diameter growth trend spanning more than 300 years; (ii) increased growth levels and trends, the latter being particularly pronounced for fir and beech; and (iii) an elevation-dependent change of fir and beech growth. Whereas in the past, the growth was highest at lower elevations, today’s growth is superior at higher elevations. This spatiotemporal pattern indicates significant changes in the growth and interspecific competition at the expense of spruce in mixed mountain forests. We discuss possible causes, consequences, and silvicultural implications of these distinct growth changes in mixed mountain forests.
STEM Degree Completion and First-Generation College Students: A Cumulative Disadvantage Approach to the Outcomes Gap

Abstract:STEM majors offer pathways to lucrative careers but are often inaccessible to first-generation students. Using data from the Education Longitudinal Study, we conducted descriptive statistics, regression analyses, and group comparisons to examine differences between first-generation students and continuing-generation students across STEM degree, non-STEM degree, dropout, and no degree completion. Findings illuminate that generation status is related to STEM completion, but other factors are driving this association; for example, pre-college STEM factors have significant predictive power. Our implications suggest a need to further examine pre-college and transfer pathways to STEM and to explore the limitations of first-generation status as a categorization.
Short communication: The genotype of growth hormone gene that affects the birth weight and average daily gain in crossbred beef cattle

Abstract. Hartatik T. , Fathoni A, Bintara S. , Ismaya, Panjono, Widyobroto B.P, Agus A, Budisatria I.G. S, Leroy P. 2020. Short communication: The genotype of growth hormone gene that affects the birth weight and average daily gain in crossbred beef cattle. Biodiversitas 21: 941-945. Growth Hormone gene has been proposed to direct search for quantitative trait loci, and polymorphisms at these loci have been associated with several production traits in bovine. This research aimed to investigate the association of the genotype of partial growth hormone gene with birth weight and average daily gain in crossbred beef cattle. The materials of this research consist of 47 samples from four different breeds. Birth weight was measured just after calving delivery from the mother. The average daily gain was calculated from the period since birth weight to the second weight (90 days). Genotyping of the growth hormone gene was determined by the sequencing and PCR-RFLP method with the AluI restriction enzyme. The association between genotype and growth traits data was analyzed using analysis of variance (ANOVA) by RStudio version 1.1. 383. The results showed the significantly different (P<0.001) in birth weight and average daily gain according to the different breed. Friesian Holstein breed showed the highest birth weight, followed by Belgian Blue Bull cross and others. The genotype valine/valine only occurs in Belgian blue bull cross and Wagyu bull cross cattle and showed moderate birth weight. Genotype affects birth weight significantly (P<0.001). The birth weight for genotype leucine/leucine, leucine/valine, and valine/valine was 34.82±18.13, 25.31±13.10, and 29.35±13.65, respectively. There was no significant difference in average daily genes according to the different genotypes. In conclusion, the growth hormone gene was probably one of the molecular genetics markers for excellent growth traits in different crossbred beef cattle.
Rolling bearing performance rating parameters: Review and engineering assessment

The choice of a rolling bearing for a particular application relies on performance rating parameters as the static, the dynamic, and the fatigue limit load of bearings. The values of these parameters define the calculated performance of the bearing. Endurance testing of high-quality rolling bearings has been used for the development of rolling bearing performance standards like the ISO 281 and ISO 76 that are commonly used throughout the industry. However, standard test methods for the measurement and validation of load ratings of rolling bearings are not available in the standards. This leads to the undifferentiated use of the “status of the art” standardized performance to the very large variety of rolling bearing types and qualities that are produced today. The current paper revisits the origin, definition, and development of rolling bearing performance parameters. A numerical study for the determination process of bearing load ratings is carried out. The results are compared with standardized values and values quoted by bearing manufacturers. This provides an overview of the load rating practices that are in use. The limitations and possible improvements of the present methodology are discussed.
