Incivility in online learning environment: Perception of dental students and faculty.

Objectives: The objectives of this study were to assess the extent of incivility and perception of dental students and faculty regarding uncivil behaviors in the online learning environment.

Methods: Incivility in online environment (IOLE) survey was used to collect data from dental students (n = 232) and faculty (n = 35) at Margalla Institute of Health Sciences, Rawalpindi, Pakistan from September to December 2021. A 4- point Likert scale was used for respondents to indicate their perceptions regarding incivility in IOLE, and a list of students' and faculty's uncivil behaviors.

Polar Ocean Observations: A Critical Gap in the Observing System and Its Effect on Environmental Predictions From Hours to a Season.

There is a growing need for operational oceanographic predictions in both the Arctic and Antarctic polar regions. In the former, this is driven by a declining ice cover accompanied by an increase in maritime traffic and exploitation of marine resources. Oceanographic predictions in the Antarctic are also important, both to support Antarctic operations and also to help elucidate processes governing sea ice and ice shelf stability.

Ocean precursors to the extreme Atlantic 2017 hurricane season.

Active Atlantic hurricane seasons are favoured by positive precursor sea surface temperature anomalies (SSTA) in the main development region (MDR, 10-20°N, 20-80°W). Here, we identify a different driving mechanism for these anomalies in 2017 (most costly season on record) compared to the recent active 2005 and 2010 seasons. In 2005 and 2010, a weakened Atlantic Meridional Overturning Circulation is the primary driver of positive SSTA.

The Low-Resolution Version of HadGEM3 GC3.1: Development and Evaluation for Global Climate.

A new climate model, HadGEM3 N96ORCA1, is presented that is part of the GC3.1 configuration of HadGEM3. N96ORCA1 has a horizontal resolution of ~135 km in the atmosphere and 1° in the ocean and requires an order of magnitude less computing power than its medium-resolution counterpart, N216ORCA025, while retaining a high degree of performance traceability.

Critical Southern Ocean climate model biases traced to atmospheric model cloud errors.

The Southern Ocean is a pivotal component of the global climate system yet it is poorly represented in climate models, with significant biases in upper-ocean temperatures, clouds and winds. Combining Atmospheric and Coupled Model Inter-comparison Project (AMIP5/CMIP5) simulations, with observations and equilibrium heat budget theory, we show that across the CMIP5 ensemble variations in sea surface temperature biases in the 40-60°S Southern Ocean are primarily caused by AMIP5 atmospheric model net surface flux bias variations, linked to cloud-related short-wave errors. Equilibration of the biases involves local coupled sea surface temperature bias feedbacks onto the surface heat flux components.

Evaluation of satellite and reanalysis-based global net surface energy flux and uncertainty estimates.

The net surface energy flux is central to the climate system yet observational limitations lead to substantial uncertainty. A combination of satellite-derived radiative fluxes at the top of atmosphere adjusted using the latest estimation of the net heat uptake of the Earth system, and the atmospheric energy tendencies and transports from the ERA-Interim reanalysis are used to estimate surface energy flux globally. To consider snowmelt and improve regional realism, land surface fluxes are adjusted through a simple energy balance approach at each grid point.

Earth's energy imbalance since 1960 in observations and CMIP5 models.

Unlabelled: Observational analyses of running 5 year ocean heat content trends () and net downward top of atmosphere radiation () are significantly correlated ( ∼ 0.6) from 1960 to 1999, but a spike in in the early 2000s is likely spurious since it is inconsistent with estimates of from both satellite observations and climate model simulations. Variations in between 1960 and 2000 were dominated by volcanic eruptions and are well simulated by the ensemble mean of coupled models from the Fifth Coupled Model Intercomparison Project (CMIP5).

Host modulation therapeutics in periodontics: role as an adjunctive periodontal therapy.

Host Modulation Therapy (HMT) is a treatment concept that reduces tissue destruction and stabilizes or even regenerates inflammatory tissue by modifying host response factors. It has been used for treating osteoporosis and arthritis for several decades. However, its use in dentistry has only been recently reported.

Loss-of-function fibroblast growth factor receptor-2 mutations in melanoma.

We report that 10% of melanoma tumors and cell lines harbor mutations in the fibroblast growth factor receptor 2 (FGFR2) gene. These novel mutations include three truncating mutations and 20 missense mutations occurring at evolutionary conserved residues in FGFR2 as well as among all four FGFRs. The mutation spectrum is characteristic of those induced by UV radiation.

The phosphoric acid leak from the wreck of the MV Ece in the English Channel in 2006: Assessment with a ship of opportunity, an operational ecosystem model and historical data.

This study evaluates the ship of opportunity (Ferrybox) concept for both sustained monitoring of UK shelf sea waters and numerical model validation. Release of phosphate from the wreck of a chemical tanker (MV Ece) in the western English Channel (49.73 degrees N, 3.

Transport of phenolic compounds from leaf surface of creosotebush and tarbush to soil surface by precipitation.

During the last 100 years, many desert grasslands have been replaced by shrublands. One possible mechanism by which shrubs outcompete grasses is through the release of compounds that interfere with neighboring plants. Our objective was to examine the movement of secondary compounds from the leaf surface of creosotebush and tarbush to surrounding soil surfaces via precipitation.

Freeze-dried, cross-linked bovine type I collagen: analysis of properties.

This study was undertaken to assess the physical and biological properties of freeze-dried cross-linked bovine type I collagen and to assess its potential for use in the guided tissue regeneration method of treatment of periodontal disease in human adult subjects. The modulus of elasticity, swelling ratio, and biodegradation rate were investigated. The collagen sponge was implanted subdermally into Sprague-Dawley rats and a histological study carried out at 2, 7, 21, 35, and 49 days post implantation.

Humoral responses to type I collagen after surgical curettage procedures employing bovine collagen implants.

Freeze-dried bovine type I collagen was implanted into periodontally diseased sites of 11 patients in an effort to repair the affected site. Peripheral blood samples taken at 0, 6 and 12 wk were assayed for antibody to human and bovine collagen using an enzyme-linked immunosorbent assay and compared with samples from 9 control subjects. Antibody levels to both human and bovine collagen, which were present at significantly higher levels in the patients at 0 wk than in the control subjects (P less than 0.
