Use of ultrasonography in assessing peri‐implant osseous defects: An in vitro study

open access: yesJournal of Periodontology, EarlyView.
Abstract Background The purpose of this study is to investigate the feasibility and diagnostic accuracy of ultrasonography in peri‐implant defect identification and evaluation, and to compare ultrasonography (USG) with cone‐beam computed tomography (CBCT) in defect identification and evaluation in an in vitro model.

Mertk drives alveolar bone loss in experimental periodontitis associated with altered neutrophil function and osteoclast recruitment

open access: yesJournal of Periodontology, EarlyView.
Abstract Background Alveolar bone loss is the hallmark of periodontitis and often remains refractory to conventional mechanical and antimicrobial therapies in chronic cases. Mer receptor tyrosine kinase (Mertk) has been implicated in bone homeostasis, yet the immune mechanisms by which Mertk modulates periodontal bone resorption remain insufficiently ...

Influence of the growing area on cone yield and alpha and beta acid content in Cascade hops: An Italian case study

open access: yesJSFA reports, EarlyView.
Abstract Background Territorial food production is a well‐known quality trait, which is attracting new customer preferences for different agricultural products. In this context, many microbreweries and agricultural breweries started to cultivate their own small hopyard to exploit the so‐called “terroir” effect.

Metallic atoms and ions in comets: Comet Halley 1986 3 [PDF]

open access: yes, 1992
The origin of metallic atoms and ions in the cometary comae is investigated theoretically. Two effects are revealed in the comas of bright comets: (1) the Na anomalous type effect is possible within the gas-dust jets of comet P/Halley 1986 3 due to ...

Hop production in a low‐trellis espalier system in the subtropical environment

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Hop cultivation (Humulus lupulus L.) is expanding into new regions, particularly under subtropical conditions. Traditionally, hop plants are trained using high‐trellis systems; however, a low‐trellis espalier structure may reduce establishment costs, facilitate phytosanitary management, and improve harvest uniformity.

On the mechanism of formation of anomalous comet tails

open access: yesOpen Astronomy
The objective of the study is to investigate the directions of potential collisions between meteoroids and comets. To this end, the inclinations of 99 comet orbits with anomalous tails were calculated in relation to 112 established meteoroid stream ...

Hunting and Imaging Comets

open access: yes, 2011
Of all the objects visible in the night sky, it is the brightest comets that have most fascinated amateur astronomers and alarmed the human population. No other objects can stretch as far across the sky as the tail of a truly great comet, or be as easily
