Leveraging Social Media to Predict COVID-19-Induced Disruptions to Mental Well-Being Among University Students: Modeling Study.

Background: Large-scale crisis events such as COVID-19 often have secondary impacts on individuals' mental well-being. University students are particularly vulnerable to such impacts. Traditional survey-based methods to identify those in need of support do not scale over large populations and they do not provide timely insights.

Minutes-duration optical flares with supernova luminosities.

In recent years, certain luminous extragalactic optical transients have been observed to last only a few days. Their short observed duration implies a different powering mechanism from the most common luminous extragalactic transients (supernovae), whose timescale is weeks. Some short-duration transients, most notably AT2018cow (ref.

Empirical networks for localized COVID-19 interventions using WiFi infrastructure at university campuses.

Infectious diseases, like COVID-19, pose serious challenges to university campuses, which typically adopt closure as a non-pharmaceutical intervention to control spread and ensure a gradual return to normalcy. Intervention policies, such as remote instruction (RI) where large classes are offered online, reduce potential contact but also have broad side-effects on campus by hampering the local economy, students' learning outcomes, and community wellbeing. In this paper, we demonstrate that university policymakers can mitigate these tradeoffs by leveraging anonymized data from their WiFi infrastructure to learn community mobility-a methodology we refer to as (WiMob).

Use of an obturator with nCPAP in a premature infant with a cleft lip and palate.

Premature infants have underdeveloped lungs and their care involves the use of nasal continuous positive airway pressure (nCPAP). For an adequate amount of oxygen to enter the lungs, the palate needs to be intact. Premature infants with a cleft lip and palate remain intubated for extended periods of time with the risks inherent in long-term intubation because of the inability to maintain nCPAP.

Impact of temperature on susceptible and resistant strains of Culex quinquefasciatus to synthetic pyrethroids.

Effect of temperature on the physiological activity and resistance status of Culex quinquefasciatus was studied. The LT(50) (lethal time) of deltamethrin, lambdacyhalothrin resistant and susceptible 4th-instar larvae decreased with increasing temperature. The LT(50) of deltamethrin resistant strains was significantly lower than the susceptible strains but not so in lambdacyhalothrin resistant strains.

Advanced placement, qualifying, and degree completion programs for internationally trained dentists in Canada and the United States: an overview.

Canadian and U.S. universities are faced with the challenge that they are not graduating enough dentists to meet the future needs of the Canadian and U.

Characterization of biochemical based insecticide resistance mechanism by thermal bioassay and the variation of esterase activity in Culex quinquefasciatus.

Biochemical mechanisms of insecticide resistance of thermal exposed and unexposed Culex quinquefasciatus strains are evaluated, which were not studied earlier. The activity of alpha- and beta-carboxylesterases and acetylcholinesterase of malathion susceptible and resistant strains were compared after thermal treatment. Three-day-old adult females were used for the malathion susceptibility test and biochemical assays, and males were used only for the susceptibility test.

Three-way trays: easy to use and abuse.

The 3-way tray technique is popular as it provides master and opposing arch impressions and an interocclusal record at the same time. Excellent clinical results can be achieved with appropriate case selection, use of rigid tray and impression materials, attention to tray positioning and other details throughout the process, and clear understanding of the limitations of the technique by the operator and dental technician.

A review on Anopheles culicifacies: from bionomics to control with special reference to Indian subcontinent.

Anopheles culicifacies, is a complex of five isomorphic sibling species A, B, C, D and E and is considered to be the major malaria vector in the Indian subcontinent. Despite numerous studies, it is difficult to have a global view of the ecological and bionomical characteristics of the individual sibling species, as different identification methods have been used. Major biological and ecological trends such as the high plasticity of behaviour and the sympatry of species are addressed.

The effect of metal ceramic restoration framework design on tooth color.

Statement Of Problem: The opacity of the metal framework in metal ceramic restorations results in reduced light transmission through the tooth that diminishes the esthetics of the tooth.

Purpose: The purpose of this study was to investigate the color change that occurs apically to a metal ceramic restoration as a result of altering the metal framework design.

Material And Methods: Color change relative to the unprepared tooth (DeltaE) between various metal ceramic restorations was determined using computer imaging and CIELAB coordinates and compared to previously determined levels of clinical acceptability.

Nanosilica-from medicine to pest control.

Nanotechnology is a broad interdisciplinary area of research, development, and industrial activity that has been growing rapidly worldwide for the past decade. More ambitious uses of nanoparticles are bioremediation of contaminated environments, controlled release of fragrances, biocides, and antifungals on textiles. Silica nanocomposites have received much attention because of its thermal degradation behavior and applications in chromatography, medicine, optics, etc.

Effect of temperature on development, eclosion, longevity and survivorship of malathion-resistant and malathion-susceptible strain of Culex quinquefasciatus.

Density of vectors and development of resistance against insecticides are two important aspects in the control of vector-borne diseases. Here, effect of temperature on different aspects of development of malathion-resistant and susceptible strains of Culex quinquefasciatus was evaluated in the laboratory. Fourth-instar larvae of C.

Sketches of surgical cases drawn in 1884-87 at the East London Hospital for Children, Shadwell.

Most of the surgical cases were under the care of the Surgeon Robert William Parker, who was on the staff of the East London Hospital for Children, Shadwell. He was born in 1842 and qualified in 1869, and after working at the London Hospital he served with distinction as a volunteer with the Anglo-American Ambulance in the Franco-Prussian War 1870-1871. Then he became Resident Medical Officer at the Children's Hospital, 49 Great Ormond Street, and later in 1876 joined the staff of the Shadwell Hospital and was an active member of several London medical societies at which he presented surgical topics and cases of paediatric interest.

Milk bolus obstruction in the neonate.

Seventeen cases of neonatal intestinal obstruction due to inspissated milk curds were seen at this hospital in the 9 years 1964-1972. The obstruction started on the 2nd to 10th day of life. Half the babies passed blood from the rectum and in most the x-rays were diagnostic.
