The world is experiencing a new wave of autocratisation, characterised by global democratic reversal. From 2010 to 2020, the share population living in autocracies increased from 48 68%. Electoral are now world's most common regime type, and along with closed they number 87 195 states. Even during height third democratisation, elections Africa rarely led an alternation power. Thirty years after...

Abstract Recently, bioabsorbable vascular stents (BVSs) are actively studied owing to their ability dissolve within the human body. However, despite advantages, BVSs often dislodge from expandable balloon‐based delivery system when transported lesion site. In this study, a novel methodology aiming at increasing retention force between stent and is presented. The breath‐figure method adopted for...

Calculating rainfall erosivity, which is the capacity of to dislodge soil particles and cause erosion, requires measurement kinetic energy (KE). Direct KE has its own challenges, owing high cost complexity measuring instruments involved. Consequently, often approximated using empirical equations derived from intensity (Ir) inputs in absence such instruments. However, KE–Ir strongly depend on lo...

The phrases "prebiotics" and "postbiotics" are used to refer various gut microbiota-related elements outcomes. Prebiotics certain dietary fibres that can withstand digestion act as a food supply for good bacteria in the colon. They not degraded by stomach acid or mammalian enzymes, they pass through digestive system undigested. idea of prebiotics was first proposed early 1900s when scientists d...

The population density and size distribution of the marine gastropod, Astraea (Lithopoma) undosa Wood 1828, at Bird Rock, Santa Catalina Island, CA, reveal an inverse relationship between population density and mean individual size, over a depth gradient. This trend may be correlated with physical and biological differences between habitats for parameters such as water motion, competitive inter...

In cardiovascular interventions, when steering catheters and especially robotic catheters, great care should be paid to prevent applying too large forces on the vessel walls as this could dislodge calcifications, induce scars or even cause perforation. To address challenge, paper presents a novel compliant motion control algorithm that relies solely position sensing of catheter tip knowledge ca...

objective: there is no definitive data on the strength of glass fiber and cast posts with different length. this in vitro study was designed to investigate and compare the effect of length on the retentive strength of glass fiber and cast posts. materials and methods: sixty recently extracted intact maxillary canine teeth were cut 1mm above the cej. the specimens were endodontically treated and...

Background. A field study conducted by researchers found the balls used by visual impairment students at school basically used the sound by a small bell inside the ball. However, the sound emitted from the ball is very limited, the ball will sound when it is moved. This makes it difficult for students with visual impairments to find a missing ball that not emitted makes a sound. Objectives. A ...
