While the high energy density of lithium metal has long been a strong driver for the development of lithium metal batteries, harnessing the full theoretical capacity in a safe, practical device requires significant advances in electrolyte design. The use of quasi-solid state electrolytes can be greatly beneficial for increasing safety, suppressing the growth of lithium dendrites and prolonging cell lifetime. Organic ionic plastic crystals (OIPCs) are a unique class of disordered solid that can support high ionic conductivities and lithium ion mobility. Until recently, OIPCs were used primarily as matrix materials and incorporated only low dopant concentrations of lithium salts. Here we report a very high lithium content electrolyte containing 90 mol% lithium bis(fluorosulfonyl)imide, Li[FSI], combined with 10 mol% of a conductive pyrrolidinium FSI-based OIPC. The resultant quasi-solid state electrolyte achieves a conductivity of 0.24 mS cm−1 at 30 °C, supports stable lithium electrochemistry and has a very good lithium ion transference number of 0.68. Symmetrical Li‖Li cell cycling is demonstrated at 0.1 mA cm−2 for 100 hours. This showcases a new approach for designing safer quasi-solid state electrolytes with high lithium content and excellent electrochemical and transport properties. [ABSTRACT FROM AUTHOR]
Pre- and post-migratory factors have been implicated in refugee children's mental health. However, findings regarding their unique and joint roles are inconsistent or nonexistent. We examined the main and interactive relations of pre-migratory life stressors and post-migratory daily hassles and routines to emotion regulation—a key marker of mental health—in 5- to 13-year-old Syrian refugee children (N = 103) resettling in Canada. Mothers and children completed questionnaires assessing pre-migratory life stressors and post-migratory daily hassles. Mothers also reported their children's adherence to family routines and emotion regulation abilities (i.e., anger and sadness regulation) via questionnaire. Overall, children who more frequently engaged in family routines showed better anger regulation. Pre- and post-migratory factors also interacted, such that greater post-migratory daily hassles were associated with worse sadness regulation for children with lower levels of pre-migratory life stressors, but were unassociated with the sadness regulation of children who experienced higher levels of pre-migratory life stressors. Results suggest that pre- and post-migratory factors play unique and joint roles in refugee children's emotion regulation during resettlement. [ABSTRACT FROM AUTHOR]

The synthesis and characterisation of new solid-state electrolytes is a key step in advancing the development of safer and more reliable electrochemical energy storage technologies. Organic ionic plastic crystals (OIPCs) are an increasingly promising class of material for application in devices such as lithium or sodium metal batteries as they can support high ionic conductivity, with good electrochemical and thermal stability. However, the choice of OIPC-forming ions is still relatively limited. Furthermore, understanding of the influence of different cations and anions on the thermal, structural and transport properties of these materials is still in its infancy. Here we report the synthesis and in-depth characterisation of a range of new OIPCs utilising the hexamethylguanidinium cation ([HMG]) with five different anions. The thermal, structural, transport properties and free volume in the different salts have been investigated. The free volume within the salts has been investigated by positron annihilation lifetime spectroscopy, and the single crystal and powder X-ray diffraction analysis of [HMG] bis(trifluoromethanesulfonyl)imide ([TFSI]) in phase I and II, [HMG] hexafluorophosphate ([PF6]) and [HMG] tetrafluoroborate ([HMG][BF4]) are reported. The HMG cation can exhibit significant disorder, which is advantageous for plasticity and future use of these materials as high ionic conductivity matrices. The bis(fluorosulfonyl)imide salt, [HMG][FSI], is identified as particularly promising for use as an electrolyte, with good electrochemical stability and soft mechanical properties. The findings introduce a range of new materials to the solid-state electrolyte arena, while the insights into the physico-chemical relationships in these materials will be of importance for the future development and understanding of other ionic electrolytes.

SINUS thrombosis, THROMBOPHLEBITIS, CRANIAL sinuses, CEREBRAL embolism & thrombosis, CRANIAL nerves, and GENDER role
Objective: Our study aims to evaluate the etiologic and clinical features of cerebral venous sinus thrombosis (CVST) in Saudi Arabia, and secondarily whether gender plays a role in CVST. Materials and Methods: Data were collected retrospectively from the stroke registry during the period from January 2008 to April 2018, and the patients with the diagnosis of CVST were identified, and data were analyzed for any gender-specific differences in clinical presentation and etiology of cerebral venous thrombosis. Results: There were 15 females while 11 males with a female:male ratio of 1.4:1. The mean age was 29.4± standard deviation 8.9 with the age range of 15–49. Headache was the most common and usually the first presenting symptoms present in 65% followed by hemiparesis and cranial nerve palsies. The first neurological examination was normal in 9/26 (34.6%) of the patients, while the common abnormality was cranial nerve palsies. Infections and trauma played an important part in risk factor analysis of our patient after the pregnancy- and hormone-related conditions. Some significant differences between the clinical presentation and risk factors among males and females were noted as age at presentation was higher in females while trauma and infections were common in male patients, although the involvement of the sinuses and response to treatment did not prove to be statistically significant. Conclusion: The results of this study were similar to the available literature with few differences. The relatively higher proportion of males in our study can be explained partly with more cases of traumatic CVST. Some important differences were noted between the risk factors and clinical presentation among genders. Large-scale prospective studies are needed to further clarify these differences.

TEACHERS, SELF-confidence, MASTER'S degree, DIGITAL technology, and EDUCATIONAL technology
Teacher confidence with technology is essential during times of rapid changes in digital technologies. In this study, we draw on theoretical accounts from creativity research and the educational technology literature to characterize an approach to teaching--a creatively focused technology fluent (CFTF) mindset. Following our work with five cohorts of educational technology master's degree students in hybrid classes designed to support this mindset (n = 74), we report evidence on such an approach. Teachers reported growth in their confidence in using not only technologies they directly experienced but also significant increases in confidence with technologies overall (even with tools they did not use/learn). We discuss implications of these findings with an emphasis upon how teacher educators can support creative teaching with technology regardless of the available technologies. [ABSTRACT FROM AUTHOR]

Objectives: To study the frequency of multiple vascular risk factors and electrophysiological severity of carpal tunnel syndrome )CTS( in Saudi diabetic patients. Methods: This retrospective cross-sectional study was conducted in Neurology Department, King Fahd Hospital of University, Al-Khobar, Kingdom of Saudi Arabia from April 2017 to March 2018 and included200 patients with CTS. Body parameters, such as blood pressure )BP(, weight, height, and body mass index )BMI(, along with laboratory and median nerve electrophysiological parameters, of diabetic and nondiabetic patients were compared, and a p-value<0.05 was considered significant. Results: Frequency of hypertension )HTN( and obesity was significantly higher in diabetic patients )p<0.05(. Mean median nerve sensory amplitude )MNSA( was lower in diabetic patients )p<0.05(. Non-recordable nerves, as well as bilateral and extremely severe CTS )p<0.05(, were more frequently seen in diabetic patients. Age, BMI, systolic BP, low serum high density lipoprotein )HDL(, high triglycerides, high fasting blood sugar, and high glycated hemoglobin )Hba1c( levels, known to affect the electrophysiological severity of CTS, had a statistically significant association with diabetes. Conclusion: Diabetes mellitus )DM( and obesity are the most commonly identified risk factors of CTS. Dyslipidemia, HTN and obesity are more frequently seen in diabetic patients with CTS. These concurrent risk factors are confounding the electrophysiological severity of CTS in these patients. Further larger-scale studies with the control of confounding factors are recommended.

NILE tilapia, CARP, FISH growth, LAKES, and SPECIES
Species composition and length-weight relationship (LWR) of fish species of Lake Oro and Lake Dakong Napo in Esperanza, Agusan del Sur, Philippines were assessed in this study. Fishes were collected using hook and line, lift net and cast net. A total of 12 species belonging to nine families were collected and where most species (75%) were introduced to Philippines freshwater bodies. Family Osphronemidae has the most number of species collected (25%) followed by Gobiidae (17%). Cyprinus carpio has the most number of individuals collected (n=124 and d=9.8/10 m²). Most number of species were collected from Lake Oro (n=10) however, diversity index was highest in Lake Dakong Napo (H=1.501). The "b" value of LWR shows that Oreachramis niloticus (b=3.1382) and C cap/o (b=2.9196) had an isometric growth while Atiabas testudineus, Osphronemusgoramy and Trichopodus trichopterus had negative allometric growth (b<3), which means that these fishes do not grow isometrically.
