Background and Aim: The present study aimed to evaluate the materials, methods, and equipment used by general dentists in southeastern Iran for endodontic treatments in 2021.   Materials and Methods: In this cross-sectional study, 121 standard questionnaires were distributed among general dentists in Rafsanjan city, Iran. The questionnaire included demographics and questions regarding the t...

Incorporation of manure into cultivated soils is generally recommended to minimize nutrient losses. A 3-yr study was conducted to evaluate sediment and nutrient losses with different tillage methods (moldboard plow, heavy-duty cultivator, double disk, and no-incorporation) for incorporation of beef cattle manure in a silage barley (Hordeum vulgare L.) cropping system. Runoff depths, sediment lo...

Samenvatting Ondanks overweldigend wetenschappelijk bewijs zijn we het niet allemaal eens over de feiten met betrekking tot een aantal belangrijke onderwerpen. Hoe kan dat? Dit artikel geeft overzicht van onderzoek naar hoe mensen vasthouden aan onjuiste overtuigingen terwijl ze geconfronteerd worden juiste informatie en wetenschapscommunicatie verbeterd om te helpen accurate komen.

We proposed an aerial projection 3D display based on integral imaging. It is composed of a projector, lens-array holographic optical element (HOE), and two parabolic mirrors. The HOE diffraction grating made by the volume holography technique. can be produced thin glass plate, it has properties lens array when Bragg condition satisfied. When beams image (EIA) are projected HOE, images reconstru...

BACKGROUND To evaluate the effect of bradykinin (BK) on TGF-β1-induced retinal pigment epithelial (RPE) cell proliferation and extracellular matrix secretion and to elucidate the relationship between BK and the Erk/Akt signaling pathway. METHODS The effects of BK on TGF-β1-induced RPE cell proliferation were examined via CCK-8 assay. Cell culture supernatant collagen I concentrations were mea...

A number of methods for producing holographic optical elements (HOEs) for use in projecting integral images in holographic stereogram printers are presented, with emphasis on application to Ultragram format one-step stereograms. Creation of HOEs to replace standard diffusion screens and enhance stereogram printer imaging properties and efficiency is discussed. Monolithic and integral holographi...

A helicopter is not possessed of an ability to fly fast compared with fixed-wing counterparts. This is a result of considerations with the main rotor. The main rotor moves in a direction very close to its plane of rotation which naturally divides it into two halves which operate under different aerodynamic conditions. One side (called the advancing side) has the rotation and translation velocit...

In this paper we study some of the arithmetic structure that is found in a special kind of semi-ring in the isols. These are the semi-rings [D(Y ),+, ·] that were introduced by J.C.E. Dekker, and that were later shown by E. Ellentuck to model the true universal recursive statements of arithmetic when Y is a regressive isol and is hyper-torre (= hereditarily odd-even = HOE). When Y is regressive...

Brow, a tall, strong, muscular man, of the cultivator caste, about 36 years of age, was admitted into the dispensary with, tetanus, which was said to have commenced four days previ? ously without apparent cause; there was no history of any wound or hurt, or of exposure to cold or wet. His state on admission was as follows :?Muscles of neck and jaw were quite rigid, so that he could not open his...
