Impact of Decreased Visibility of Deep Medullary Veins on White Matter Integrity in Patients with Cerebral Small Vessel Disease.

BACKGROUND Based on susceptibility-weighted imaging (SWI) visibility, deep medullary vein (DMV) scores are related to white matter damage (WMD) in patients with cerebral small vessel disease (CSVD). However, whether mechanisms are associated with DMV changes is unclear. We examined extracellular fluid (ECF) roles in white matter associations between DMV scores and white matter integrity (WMI) in patients with CSVD. METHODS We examined magnetic resonance imaging (MRI) and clinical data from 140 patients with CSVD. DMV scores (0-18) were assigned on SWI according to DMV anatomic regions and signal continuity/visibility. WMI and ECF volumes were evaluated using free water (FW) and fractional anisotropy (FA) values by diffusion tensor imaging (DTI). RESULTS DMV scores were independently associated with FA after adjusting for vascular risk factors, age, white matter hyperintensity (WMH) volume, and CSVD burden [β (95% confidence interval (CI)): -0.219 (-0.375, -0.061), p = 0.006]. We also observed a significant indirect effect of DMV scores on FA in white matter (mediated by FW in white matter) after controlling for age, vascular risk factors, WMH volume, and CSVD burden. CONCLUSIONS DMV scores were independently related to WMI and mediated by ECF in the white matter of patients with CSVD.
The Crustal Magmatic Structure Beneath the Denali Volcanic Gap Imaged by a Dense Linear Seismic Array

The crustal structure in south‐central Alaska has been influenced by terrane accretion, flat slab subduction, and a modern strike‐slip fault system. Within the active subduction system, the presence of the Denali Volcanic Gap (DVG), a ∼400 km region separating the active volcanism of the Aleutian Arc to the west and the Wrangell volcanoes to the east, remains enigmatic. To better understand the regional tectonics and the nature of the volcanic gap, we deployed a month‐long north‐south linear geophone array of 306 stations with an interstation distance of 1 km across the Alaska Range. By calculating multi‐component noise cross‐correlation and jointly inverting Rayleigh wave phase velocity and ellipticity across the array, we construct a 2‐D shear wave velocity model along the transect down to ∼16 km depth. In the shallow crust, we observe low‐velocity structures associated with sedimentary basins and image the Denali fault as a narrow localized low‐velocity anomaly extending to at least 12 km depth. About 12 km, below the fold and thrust fault system in the northern flank of the Alaska Range, we observe a prominent low‐velocity zone with more than 15% velocity reduction. Our velocity model is consistent with known geological features and reveals a previously unknown low‐velocity zone that we interpret as a magmatic feature. Based on this feature's spatial relationship to the Buzzard Creek and Jumbo Dome volcanoes and the location above the subducting Pacific Plate, we interpret the low‐velocity zone as a previously unknown subduction‐related crustal magma reservoir located beneath the DVG.
Emotional Adjustment among Adolescent Students with and without Specific Learning Disabilities

Adolescence is a psychologically vulnerable stage in which problems of emotional adjustment and psychological well-being can appear. The aim of this study is to analyse the relationship and comparison of emotional deficits and resources among adolescents with or without specific learning disabilities. We evaluated 80 students distributed into two groups: 40 adolescents with specific learning disabilities and 40 normative adolescents matched with the previous group in terms of age, sex, and school year. The study variables are internalising problems (anxiety and depression), externalising problems (aggression, anger control, defiant behaviour, and antisocial behaviour), and personal resources (self-esteem, social competence and integration, and awareness of problems), evaluated by means of the SENA test. The results indicate a positive relationship between externalising and internalising problems and a negative relationship between the latter and some personal resources in both groups. We also found that adolescents with specific learning disabilities displayed more internalising and externalising symptoms than their peers, greater awareness of their emotional difficulties, and lower self-esteem and social integration and competence. The findings highlight the need for preventive interventions that promote the psychological well-being and mental health of adolescents within the school setting at an early age.
Improving Automotive Component Supplier Service through Physical Distribution Activities to Original Equipment Manufacturers (OEMs)

Purpose/objectives: The purpose of this study was to investigate whether physical distribution activities can significantly improve customer service for automotive component suppliers to Original Equipment Manufacturers (OEMs) in the Eastern Cape. Design/methodology/approach: By means of non-probability sampling, namely convenience sampling, 50 automotive component suppliers in the Eastern Cape were visited. Each business firm received four questionnaires to be completed by logistics practitioners. Altogether, 126 usable questionnaires were returned. The data were collected by means of a survey using a self-administered, structured questionnaire. Findings/results: The results indicated that physical distribution activities, such as transportation management and order processing, were significant predictors of customer service. Practical implications: The results have managerial implications where the logistics department should continuously update its transportation and order processing systems to keep abreast of the best practices within the automotive industry. The results could be used by managers to highlight the benefits of improved customer service, focusing on a firm’s transportation and order processing activities. Originality/value: Based on the results of the study, it is recommended that automotive component suppliers in the Eastern Cape employ transportation management and order processing (activities of physical distribution) to improve customer service. It is also recommended that the automotive component suppliers regularly benchmark their logistics practices against world-class business firms, as the results may have a positive effect on the way transportation and order processing activities are managed and executed if customer service is to be improved.
Comparison of Vascular Complications after Arterial Sheath Removal using Manual Compression Method and ClampEase Method in Patients Undergoing Coronary Angiography

Introduction: Angiography stands as the paramount and definitive diagnostic method for coronary artery disease. However, akin to various other invasive procedures, it may carry a multitude of complications. This study sought to assess the incidence of vascular complications post-arterial sheath removal, comparing the use of a ClampEase device against manual compression. Methods: This quasi-experimental clinical trial involved patients undergoing angiography at the post-angiography ward in Isfahan, Iran. A total of 91 patients were selected through convenience sampling and randomly assigned to either the manual compression or ClampEase device groups. Monitoring common vascular complications like hemorrhage, hematomas, and ecchymosis occurred up to 24 hours post-arterial sheath removal. Data were collected using a digital scale model DM3, a transparent flexible ruler, and a questionnaire named ‘vascular complications after angiography. ’ Analysis was performed using SPSS software version 13. Results: Statistical analysis revealed that, when compared to the manual method, compression with the ClampEase device led to fewer vascular complications in patients and a quicker return to homeostasis. Conclusion: The findings underscore that the ClampEase method is a safer alternative with fewer vascular complications than the manual compression method. This discovery has implications for reducing hospital costs and length of stay. The ClampEase device is associated with a swifter time to hemostasis, contributing to enhanced patient comfort and acceptance.
Effects of coastal road spacing on deposition of tsunami-borne sand.

Large-scale infrastructure for tsunami damage mitigation includes tidewater control forests and tide embankments. It is said that installing a tidewater control forest of 200 m in width along the coast is effective in mitigating tsunami damage. Since the East Japan Great Earthquake, tide embankments of about 7 m high have been under construction on coasts of tsunami-hit areas. Restoration and installation of tidewater control forests require many years, and the construction of large-scale tide embankments requires enormous cost. This study focuses on existing roads in the coastal areas. We investigated the effects of road, depending on their conditions of spacing, on tsunami sand deposition. A 0.3 m-wide, 12 m-long open channel was used for tsunami experiments. To simulate a tsunami, a removable barrier was set near the upstream end of the channel to retain water. The barrier was lifted suddenly to generate a bore. The scale of the model was 1/100. A certain amount of sand and models of a tidewater control forest, a tide embankment and roads made of acrylic were placed at the longitudinal midpoint of the channel. The movement of sand carried by the reproduced tsunami was observed. Several combinations of the tidewater control forest, tide embankment and three roads were used in the tsunami reproduction experiment, with the spacing changed for each experiment. As the result of experiments, it was clarified that when the spaces between the roads were wide, the amount of deposited sand was controlled better. It was also clarified that the amount of sand deposition at the time of a tsunami in a coastal area was able to be controlled effectively by combining roads with wide spacing between them with a tidewater control forest or a tide embankment.
Psychometric Assessment of Infant Colic Scale in Iranian Population

Introduction: Infant colic, causing excessive crying, poses anxiety for parents and a challenge for pediatricians and nurses. The Infant Colic Scale (ICS) serves to assess the severity and causal factors of colic. Despite its significance, the psychometric properties of ICS have not been evaluated in the Iranian population. This study seeks to address this gap by assessing the psychometric properties of ICS in Iran. Methods: A sample of 220 mothers with 2–16-week-old term infants diagnosed with infantile colic was selected through convenience sampling. Following forward and back-translation, the face validity, content validity, and construct validity of ICS were systematically evaluated. Reliability was examined through both internal consistency (Cronbach’s alpha) and test-retest stability methods. Results: Content validity index (CVI) and content validity ratio (CVR) values for ICS were 0.94 and 0.81, respectively. The good fit indices confirmed the validity of the five-factor structure. Cronbach’s alpha coefficient and intraclass correlation coefficient (ICC) were 0.71 and 0.94, respectively. Conclusion: The Persian version of ICS is a valid and reliable tool, suitable for assessing infantile colic in the Iranian population. Future studies and clinical practice can utilize this tool to identify major causes of this disorder in the Iranian context.
Recent Trends in the Petasis Reaction: A Review of Novel Catalytic Synthetic Approaches with Applications of the Petasis Reaction

The Petasis reaction, also called the Petasis Borono–Mannich reaction, is a multicomponent reaction that couples a carbonyl derivative, an amine and boronic acids to yield substituted amines. The reaction proceeds efficiently in the presence or absence of a specific catalyst and solvent. By employing this reaction, a diverse range of chiral derivatives can easily be obtained, including α-amino acids. A broad substrate scope, high yields, distinct functional group tolerance and the availability of diverse catalytic systems constitute key features of this reaction. In this review article, attention has been drawn toward the recently reported methodologies for executing the Petasis reaction to produce structurally simple to complex aryl/allyl amino scaffolds.
Dandy-Walker Syndrome: Delayed Acute Presentation With Unusual Symptoms

Dandy-Walker syndrome (DWS) is a rare congenital brain malformation defined by the presence of an expanded posterior fossa, full or partial absence of the cerebellar vermis, and a cystic expansion of the fourth ventricle. We report an 18-month-old girl with DWS presenting with atypical clinical manifestations and unusual symptoms. She initially presented with persistent vomiting and abdominal pain for four days, not responding to antiemetic medication. In addition, she was found to have abnormal postural arching of the back, extension of the lower limbs, and neck extension. MRI and CT head suggested Dandy-Walker syndrome with hydrocephalus (the lateral ventricle, third ventricle, and fourth ventricle are all significantly dilated with evidence of trans-ependymal cerebrospinal fluid permeation, severe compression anterior displacement of the brain stem). The patient underwent urgent, lifesaving right sub-occipital craniotomy, evacuation, and decompression of the posterior fossa cyst and external ventricular drain (EVD) insertion along with left supra-tentorial EVD insertion. A series of brain magnetic imaging and CT brain post-procedure studies showed a significant reduction in the size of the ventricular system and mass effect on the brain stem.
Elaeis guineensis leaves for potential renewable sub‐bituminous coal: Optimization of biochar yield by response surface methodology and product characterization

Pyrolysis of oil palm biomass residue can convert the rich organic matter in biomass into sustainable green energy, thereby addressing the challenge of surplus oil palm biomass residue generated during cultivation. Nonetheless, the pyrolysis of oil palm leaves (OPLs) has received limited attention. In this study, design of experiment‐response surface methodology (DoE‐RSM) was employed to identify the optimal combination of reaction temperature, residence duration, and nitrogen (N₂) flow rate for maximum biochar yield. The elemental analysis, high heating value (HHV), functional group, morphology, pore structure, and thermal behavior were assessed. By varying the operational parameters using response surface methodology, the biochar yield increased by 32.6–85.3%. The DoE‐RSM predicted a theoretical yield of 52.1% at 344 °C, 146 min, and 3.2 scfh N₂ flow rate. The experiment confirmed a comparable yield of 53.7% at the stated parameters. The HHV of 24.14 MJ kg−1 was recorded under optimal conditions, and was comparable to sub‐bituminous and bituminous coal. Fourier transform infrared analysis validated the OPL biochar by weakening O‐H, C=O, C‐OH, and C‐H peaks. Scanning electron microscopy images revealed enlarged pores and altered morphology in the OPL biochar. X‐ray diffraction showed lower crystallinity of the OPL biochar than the feedstock. Raman spectroscopy showed higher ID/IG, indicating a more disordered carbon structure in the OPL biochar. Thermogravimetric analysis confirmed higher temperature for main devolatilization of OPL biochar, and the differential thermogravimetric analysis curve pattern resembled that of Mukah Balingan coal. The findings are helpful for an initiative to convert a large amount of leftover OPLs produced during cultivation and to turn them into high value‐added material for a sustainable contribution to a circular carbon economy.
STUDENT LOANS: LESSONS FROM BORROWERS

The study presents the results and the analysis of a survey of recent student loan borrowers. The fields of study that result in the highest disbalance between the amount borrowed and the generated earnings are identified. Additionally, the survey results shed light on the post-graduation spending behavior of the borrowers. The results indicate that the present student loan crisis may, at least in part, be caused by the selection of the major area of study and by the post-graduation personal consumption overadjustment of individuals from several (less financially lucrative) fields of study.
How Does Interhemispheric Coupling Contribute to Cool Down the Summer Polar Mesosphere

AbstractInterhemispheric coupling is commonly associated with events of high planetary wave activity in the winter stratosphere triggering a heating of the polar mesopause region in the opposite hemisphere. Here, a more fundamental role that this mechanism plays in the absence of planetary wave variability is highlighted. This study focuses directly on the mesospheric part of the coupling chain, which is induced by the gravity wave drag in the winter mesosphere. To investigate the effect that the winter residual flow has on the summertime high-latitude upwelling, the Kuhlungsborn Mechanistic General Circulation Model (KMCM) is used to compare a control simulation to runs where the parameterized gravity waves are removed from the winter hemisphere. The model response in the summer mesosphere reveals that the winter mesospheric residual circulation fosters a net (and substantial) cooling of the summer polar mesopause. These results offer an extension of the current view of interhemispheric coupling: from a .
Synthesis of Composite Corrosion Inhibitor Based on Maleic Anhydride, Monoethanolamine and Phosphate Acid

In this article, the optimum conditions for the synthesis of corrosion inhibitors based on maleic anhydride, monoethanolamine, and phosphoric acid and the inhibitory efficiency of the obtained inhibitor are studied. In this case, the mole ratio of the starting materials was 2 moles (122 g) of monoethanolamine: 1 mole (98 g) of maleic anhydride: 1 mole (98 g) of phosphoric acid, and the yield of the reaction was 92.5%. The IR spectra of the structure of this obtained inhibitor were studied. The inhibition efficiency of this corrosion inhibitor was measured by the gravimetric method according to GOST 9.506-87 in 1M HCl + 200 mg/l NaCl and 0.5 HCl + 200 mg/l NaCl environments. The inhibition efficiency was 93.15% and 92.86%, respectively. reached According to the results of the electrochemical research, the inhibition efficiency was 91.5%. In addition, Langmuir, Frumkin, and Tyomkin isotherms of the inhibition mechanism of the inhibitor were studied. The effect of the inhibitor on the steel surface was studied with a scanning electron microscope.

Objectives: Weight counseling is an inevitable process for patients with obesity who intend to lose weight; however, the contents of real-world counseling practices remain uncertain in Korean medicine (KM) practice. This study aimed to explore the structure and constituents of obesity counseling in KM.Methods: Qualitative methods were used to explore the structure of weight counseling and clinicians' approaches to weight counseling, particularly the advice and main constituents of weight counseling in KM. Nine KM clinicians (4 women, 5 men) from nine clinics completed face-to-face, individual and semi-structured interviews from September 2019 to February 2020 in Seoul, Daejeon, Cheonan, Seongnam, Asan, and Hwaseoug. The interviews were digitally recorded, transcribed verbatim, and categorized based on their constituents.Results: During weight loss counseling, the six principal constituents of KM identified were: planning with patients, motivation, correcting misinformation on weight loss, dietary and exercise advice, medication guidance, and customized guides for each type.Conclusion: Clinicians with in-depth knowledge about obesity prescribed personalized guidance for exercise, diet, and medication through an integrative approach. The study results provide an in-depth understanding of weight counseling in KM. These six constituents could guide the counseling provided by clinicians in obesity care.
Patterns of Sea Ice Retreat in the Transition to a Seasonally Ice-Free Arctic

AbstractThe patterns of sea ice retreat in the Arctic Ocean are investigated using two global climate models (GCMs) that have profound differences in their large-scale mean winter atmospheric circulation and sea ice drift patterns. The Community Earth System Model Large Ensemble (CESM-LE) presents a mean sea level pressure pattern that is in general agreement with observations for the late twentieth century. The Community Climate System Model, version 4 (CCSM4), exhibits a low bias in its mean sea level pressure over the Arctic region with a deeper Icelandic low. A dynamical mechanism is presented in which large-scale mean winter atmospheric circulation has significant effect on the following September sea ice extent anomaly by influencing ice divergence in specific areas. A Lagrangian model is used to backtrack the 80°N line from the approximate time of the melt onset to its prior positions throughout the previous winter and quantify the divergence across the Pacific and Eurasian sectors of the Arctic.

Synthesis and Estimation of the Insecticide and Antibacterial Activities for Some New Amide Derivatives

In this work, new compounds of amide derivatives (C1-C3) were synthesized through the conversion reaction of p-chloroaniline to diazonium salt (B1), which reacts with aniline to form a new azo-compound (B3). Synthesized of p-alkoxybenzoic acid (A1-A3) and reacts with SOCl2 to form A4-A6 compounds that react with B3 compound to form amide compounds (C1-C3). The synthesized derivatives were tested by docking analysis and characterized via FTIR, 1H-NMR spectra. In the docking study, the interaction diagram also displays many van der Waals interactions, which are used to estimate the synthetic compounds' activity as insecticides like anti-termites. Heptyl came in first on the binding score, followed by octyl and then nonyl. Due to the compounds' modified conformation in interacting with the enzyme's binding pocket, the length of the alkyl residue of the derivative adversely impacted their binding inhibition. The synthesized compounds (C1 and C3) give a good result as anti-E. coli and anti-Staphylococcus strains.
