Impacts of Seizure Care Simulation Intervention on Mothers’ of Epileptic Children Efficiency, Believes, Anxiety and Seizure Care

Background; Epilepsy is one of the most common neurological disorders among children. Lack of knowledge about safe care among mothers whom are the first care providers will affect children life and mother self efficiency. Aim of the study; to assess impacts of seizure care simulation intervention on mothers’ of epileptic children efficiency, believes anxiety and seizure care. Design: Quasi experimental research design was used. Sample & setting; 73 mothers admitted with their epileptic children in neurology & pediatric departments from June - July 2018 at Menofyia university hospital /Shibeen El Kom and accept to participate in the study were included. Intervention was given to them into 5 sessions post test was conducted after one month post hospital discharge. Results; 70% of mothers aged 20-40 years and 78% of them their epileptic children were male. Regarding subjects knowledge; 60% of them had correct answer post the intervention related to definition of epilepsy, 70% causes of epilepsy and 80% of them know correctly pre seizure manifestation, also about two thirds of them post one month from the intervention had correct answer regarding care pre seizure attacks, care during seizure and correct care post seizure attacks with significant difference were found pre and post one month from intervention. Regarding maternal self efficiency level nearly all mothers post one month from the intervention very sure that; they can know if their child has seizure attack before it happen and can manage seizure effectively. Maternal believes about epileptic children abilities were improved post one month from intervention. There was significant difference in maternal seizure management practice pre and post one month from intervention also maternal anxiety was decrease post one month from intervention. Conclusion: Seizure care simulation intervention produces significant improvement in maternal knowledge, change their attitude and improve their care practice which decrease maternal anxiety and raise their self efficiency. Recommendation: Mothers of epileptic children need special preparation through well planned educational intervention which support them to practice effective physical &psychological care and maintain their physical and psychological safety, well being and decrease their anxiety level regarding their children health and all family members wellbeing.
Fear of COVID-19 and Its Association With Health Literacy in Elderly Patients

One of the groups most negatively affected by the epidemic process has been the elderly patients. In this process, it is of great importance to determine the fear levels of the patients and to evaluate the factors that may be related. With this approach, this study aimed to examine the relationship between the fear of COVID-19 and health literacy scores of elderly patients living in Kahramanmaraş City, Turkey. Another aim of the study was to investigate whether the participants’ COVID-19 fear change according to various socio-demographic characteristics. The convenience sampling method were used and 266 of valid samples were collected. Descriptive statistics, t-test, ANOVA, Pearson correlation analysis, simple and multiple linear regression analysis techniques were used. The results obtained from the study showed that COVID-19 fear status of the participants were moderate while the health literacy scores were low. Higher health literacy was associated with lower fear of COVID-19. In addition, it was determined that the fear of COVID-19 showed statistically significant differences according to education level, insurance status, smoking status, follow the news status and marital status. As a result, it has been observed that the level of health literacy can be effective in protecting elderly patients from fear. Longitudinal studies have been proposed to determine whether this relationship is causal or not.
Vortex Dynamics of Free-to-Roll Slender and Nonslender Delta Wings

Experiments were conducted on various free-to-roll delta wings with sweep angles in the range of 40―70 deg in a wind tunnel. For low sweep angles, nonzero trim angles are observed until the wing stalls after which the trim angle becomes zero. The magnitude of the roll trim angle decreases with increasing sweep angle and almost disappears for the most slender wing. In a certain range of sweep angles, and just before the stall, large amplitude self-induced roll oscillations with nonzero mean were observed for thin wings with sharp leading edges for which separation point is fixed. Two different regions of angle of attack with free-to-roll oscillations were found for certain sweep angles. Velocity measurements suggest that the oscillations are initiated by the increasing proximity of the shear layers as the angle of attack is increased. Possible mechanisms of the self-induced roll oscillations based upon the phase-averaged velocity measurements have been proposed, incorporating varying vortex size and strength as well as the movement of the shear-layer reattachment locations. Hysteresis and time lag effects are significant even though typical dimensionless frequencies are very low.
User acceptance studies for LED office lighting: Lamp spectrum, spatial brightness and illuminance

In order to determine user acceptance for light-emitting diode (LED) office lighting, a full-scale experiment was conducted in two mock-up office rooms with different light spectra at two different illuminances. Six LED spectra and two fluorescent lamp spectra were used for the study. There were four spectra (three LED spectra and one fluorescent lamp spectrum) at a correlated colour temperature (CCT) of 4000 K and four spectra (three LED spectra and one fluorescent lamp spectrum) at a CCT of 6500 K. Forty observers evaluated the lighting environments under different spectra and rated the lighting environments sitting at a working desk and at a meeting table. The observers preferred the task illuminance of 500 lux to 300 lux and the CCT of 4000 K to 6500 K. The observers preferred the spectral power distributions (SPDs) under which they found the lighting environment to look brighter and more spacious. The observers’ preferences showed that spatial brightness was affected by illuminances and SPDs. The lighting with a SPD having higher values of a reference-based metric (CQS Colour Preference Scale) and an area-based metric (CQS Gamut Area Scale or Gamut Area Index) was preferred most at a CCT of 4000 K. It was also found that the lighting with the fluorescent lamp was least preferred among the other SPDs at the CCT of 4000 K. The observers preferred both the simple and complex SPDs over fluorescent lamps at 4000 K in the office environment. It would be a good option to develop simple LED SPDs while maintaining the criteria of good lighting for an office environment.
Whole-Exome Sequencing Identifies a Novel POLG Frameshift Variant in an Adult Patient Presenting with Progressive External Ophthalmoplegia and Mitochondrial DNA Depletion

Mitochondrial DNA (mtDNA) depletion syndromes are a group of autosomal recessive disorders associated with a spectrum of clinical diseases, which include progressive external ophthalmoplegia (PEO). They are caused by variants in nuclear DNA (nDNA) encoded genes, and the gene that encodes for mtDNA polymerase gamma (POLG) is commonly involved. A splice-site mutation in POLG, c.3104+3A > T, was previously identified in three families with findings of PEO, and studies demonstrated this variant to result in skipping of exon 19. Here, we report a 57-year-old female who presented with ophthalmoplegia, ptosis, muscle weakness, and exercise intolerance with a subsequent muscle biopsy demonstrating mitochondrial myopathy on histopathologic evaluation and multiple mtDNA deletions by southern blot analysis. Whole-exome sequencing identified the previously characterized c. 3104+3A > T splice-site mutation in compound heterozygosity with a novel frameshift variant, p.Gly23Serfs∗236 (c.67_88del). mtDNA copy number analysis performed on the patient's muscle showed mtDNA depletion, as expected in a patient with biallelic pathogenic mutations in POLG. This is the first reported case with POLG p.Gly23Serfs∗236, discovered in a patient presenting with features of PEO.
Variation in Root Exudate Composition Influences Soil Microbiome Membership and Function

Decrypting the chemical interactions between plant roots and the soil microbiome is a gateway for future manipulation and management of the rhizosphere, a soil compartment critical to promoting plant fitness and yields. Our experimental results demonstrate how soil microbial community and genomic diversity is influenced by root exudates of differing chemical compositions and how changes in this microbiome result in altered production of plant-relevant metabolites. ABSTRACT Root exudation is one of the primary processes that mediate interactions between plant roots, microorganisms, and the soil matrix, yet the mechanisms by which exudation alters microbial metabolism in soils have been challenging to unravel. Here, utilizing distinct sorghum genotypes, we characterized the chemical heterogeneity between root exudates and the effects of that variability on soil microbial membership and metabolism. Distinct exudate chemical profiles were quantified and used to formulate synthetic root exudate treatments: a high-organic-acid treatment (HOT) and a high-sugar treatment (HST). To parse the response of the soil microbiome to different exudate regimens, laboratory soil reactors were amended with these root exudate treatments as well as a nonexudate control. Amplicon sequencing of the 16S rRNA gene illustrated distinct microbial diversity patterns and membership in response to HST, HOT, or control amendments. Exometabolite changes reflected these microbial community changes, and we observed enrichment of organic and amino acids, as well as possible phytohormones in the HST relative to the HOT and control. Linking the metabolic capacity of metagenome-assembled genomes in the HST to the exometabolite patterns, we identified microorganisms that could produce these phytohormones. Our findings emphasize the tractability of high-resolution multiomics tools to investigate soil microbiomes, opening the possibility of manipulating native microbial communities to improve specific soil microbial functions and enhance crop production. IMPORTANCE Decrypting the chemical interactions between plant roots and the soil microbiome is a gateway for future manipulation and management of the rhizosphere, a soil compartment critical to promoting plant fitness and yields. Our experimental results demonstrate how soil microbial community and genomic diversity is influenced by root exudates of differing chemical compositions and how changes in this microbiome result in altered production of plant-relevant metabolites. Together, these findings demonstrate the tractability of high-resolution multiomics tools to investigate soil microbiomes and provide new information on plant-soil environments useful for the development of efficient and precise microbiota management strategies in agricultural systems.
Two-stage clustering algorithm for block aggregation in open pit mines

One of the main obstacles in using exact optimisation methods for open pit production scheduling is the size of real mining problems, which forms an intractable optimisation problem. The objective of this paper is to develop, implement, verify and validate a clustering algorithm for block aggregation for the purpose of production scheduling. The algorithm aggregates blocks into selective mining units based on a similarity index which is defined based on rock types, ore grades and distances between blocks. A two-stage clustering approach based on agglomerative hierarchical algorithm and tabu search is developed and tested. The algorithm is validated by a case study on an iron ore life of mine production schedule. The results illustrate that the size and shape of the aggregated blocks have 10–15% effect on the project's net present value and also a significant impact on the practicality of long term production schedules genereated.
High Expression of TIM 3 and Galectin 9 on Immunohistochemistry Staining of Tumor Specimen at Diagnosis in Pediatric Patients with Ewing Sarcoma

Significant progress has been made in the advancement of immune system modulation for cancer treatment in recent years. In particular, immune checkpoint inhibitors and chimeric antigen receptor (CAR) T-cell therapy have demonstrated remarkable clinical benefit in relapsed/refractory cancers. However, our understanding of the immuno-oncologic landscape in pediatric solid tumors remains limited and is a barrier to continued progress. We examined the immunohistochemical expression of checkpoint receptors PD-1, TIM-3, LAG-3 and their respective ligands in various pediatric cancers at diagnosis and found high expression of TIM-3/Galectin-9 in the infiltrating cells of Ewing sarcoma. Location of checkpoint receptor/ligand expressions is important, as some staining patterns were only seen along tumor borders. Finally, peripheral T cell function varied significantly among different tumors supporting a complex relationship between the tumor microenvironment and the global immune system.
A field test for evaluating high performance concrete covercrete quality

Since in most deterioration mechanisms fluid ingress plays an important role, the surface skin of concrete provides the initial resistance to such factors as de-icer salt penetration, freeze-thaw resistance, and sulphate attack. Surface durability testing must evaluate resistance to the predominant mechanism of initial fluid ingress: capillary absorption or sorptivity. The primary focus of this study was to develop a test device suitable for nondestructive field use to evaluate the durability of covercrete by determining the rate of absorption of concrete, including high performance concrete. This type of testing device must be simple to use, easily handled in the field, portable, and inexpensive. This particular device allows for ease of operation and accommodates a wide range of surface applications such as vertical, horizontal, or sloped surfaces, and smooth or rough finishes, while providing quick, consistent, and meaningful results. The development of this apparatus was based on principles presented .
Auctioning IT Contracts with Renegotiable Scope

Motivated by challenges facing IT procurement, this paper studies a hybrid procurement model in which a reverse auction of a fixed-price IT outsourcing contract may be followed by renegotiation to extend the contract’s scope. In this model, the buyer balances the needs to incentivize noncontractible vendor investment and to curb the winning vendor’s information rent by choosing the initial project scope and the buyer’s investment in the quality of the project. We find that a buyer may benefit from inducing ex post renegotiation to motivate vendor investment, especially when the winning vendor has high bargaining power and the quality uncertainty is low. Broadening the initial scope reduces information rent but leaves little room for ex post renegotiation and, hence, discourages vendor investment, whereas increasing the buyer’s investment has opposite effects. Interestingly, the two measures can be strategic substitutes or complements depending on the likelihood of the renegotiation and the two parties’ bargaining powers. The buyer may strategically set a low initial project scope and high investment to incentivize renegotiation and vendor investment, which may explain why many IT outsourcing projects start small and allow expansions. Our findings also generate several testable predictions for IT outsourcing. This paper was accepted by Kartik Hosanagar, information systems.
A Study on the Mechanism and Strategy of Cross-Regional Emergency Cooperation for Natural Disasters in China—Based on the Perspective of Evolutionary Game Theory

Natural disasters have obvious cross-regional and compound characteristics. Cross-regional emergency cooperation for natural disasters deepens the diversification of coordination relations and the complexity of interaction modes among emergency response organizations, including horizontal and vertical organizational interactions. In order to clarify the cooperation mechanism of emergency organizations during cross-regional emergency cooperation for natural disasters and to explore the key factors that affect the cooperative relationships of emergency organizations, in this study, a game model is constructed based on evolutionary game theory, which is composed of local, neighboring, and central governments. Then, the stability of the emergency game strategy is analyzed. On this basis, a numerical simulation is used to simulate the dynamic evolution trajectory of the game system. The results show that there is an embedded mutual promotion mechanism that evolves towards a positive emergency strategy combination among the game subjects. The selection strategies of the game subjects show the characteristics of consistency and the following: enhanced cooperation efficiency between local and neighboring governments, emergency capital stock, and shared resources, therefore, guiding social emergency forces to actively participate in emergency operations. Strengthening the emergency dispatching strength of the central government and the effectiveness of central–local emergency dispatching, can support the performance of cross-regional emergency cooperation for natural disasters. Furthermore, the efficiency of cooperation between local and neighboring governments will be enhanced.
Efficacy of Ozone Gas against All Stages of Red Flour Beetle, Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae) at Different Temperatures and Exposure Periods

Ozone efficacy (approximately of 600 Mg.hr-1) was evaluated against Red Flour Beetle’s (RFB, Tribolium castium (Herbst)) eggs, larvae, pupae and adults at different temperatures (35, 40 and 45 ° C) and exposure times (1, 2, 4, 6, 8, 10 hours) under laboratory. The control treatments included above thermal levels without ozone at the mentioned exposure periods. The results indicated ozone effectively suppressed hatching with increasing temperature. The hatch egg rates was reduced to 0 % in the treated treatments after 10 h at 45° C. However, mortality rates of RFB were increased with maximizing of the exposure time to ozone. After 10-h exposure to ozone at the lowest temperature 35˚ C, complete mortality (100%) or few survivals of RFB were recorded in the susceptible stages (larvae and adults). Also, the complete mortality of adults and larvae resulted after an exposure to ozone at 40 ° C for 10 hours, compared than the high survival rates at the pest’s stages at 30 and 40° C, even after 10 hours of monitoring time. However the exposure time which is required to 100% mortality was decreased to 4 hours at 45 ° C, comparing to the thermal treatment only (control) which needed more time (6 h) for 100% of mortality. In conclusion, ozone application showed the efficacy on the mortality at all stages of RFB and the temperature was a potential factor enhancing the application of ozone for RFB control.
Assessment of Groundwater Recharge Potential Depending on Morphologic Analysis in East of Wasit, Southeastern Iraq

Modern technologies are used for watershed management to cope with drought risks in arid and semi-arid regions. The study aimed to conduct a morphometric analysis and know potential groundwater recharge areas in the eastern region of Wasit Province. Remote sensing and GIS data were used for morphometric analysis. The morphometric analysis results adopted the Digital Elevation Model. The results of the analysis were verified by matching the results with what exists in reality. The area of the first basin was 1482.017, as it is the largest basin from the area, with a percent of 51.228% of the total area of all basins. The percentage of first-degree flows reached 83.37% in the first basin, 74.14% percent in the second basin, 75.51% in the third basin, and 75.75% in the fourth basin from all streams in each basin. The bifurcation rate (3.135-4.233), Stream frequency range values (0.543-0.332), drainage texture coarse, low drainage density that ranged between 0.986-1.14 km/km2 elongation ratio ranging from 0.348-0.624 form factor (0.095-0.316). The basins' circularity (0.105-0.238) relief value (951-112) m infiltration number value (0.369-0.535). All basins have a longitudinal shape and lead to the formation of floods and rapid currents, which exposes the region to rapid seasonal floods and the creation of flash floods that cause soil erosion and analyses the drainage intensity results. It was low, and this is an indication that the ground has high permeability. The flow frequency results indicate that the area is semi-arid and exposed to small amounts of rain and coarse drainage texture by comparing the result parameters from morphometric analysis results for each basin. The potential recharge areas of groundwater in the study area can be known, n as the analysis results showed that recharge potential occurs in all basins. The highest groundwater recharge is possible in the third basin and the lowest in the first basin. Morphometric analysis was performed by ARC-GIS(Arc-map10.4).
A very small double C-patch antenna contained in a PCMCIA standard PC card

A very small size partially shorted double C-patch antenna on a truncated ground plane has been successfully integrated to a Personal Computer Memory Card International Association (PCMCIA) card. The antenna has the same performance and characteristics in free space and inside the PCMCIA slot in any personal computer. The card has a good reception sensitivity from any direction and regardless of its orientation. That is because the used partially shorted double C-patch antenna has isotropic radiation patterns and it is sensitive to both vertically and horizontally polarized radio waves. Furthermore, double C-patch antennas have an excellent performance beside the human body. Hence, the PCMCIA card has also a high reception sensitivity when it is hand-held and inside the operator's pocket.
