This thing's finally done! I've mostly been doing quick artistic pieces lately and wanted to push myself with something intensive and challenging again. So here's a Rennaissance style wall painting of my character Peregrine that exists in a closet under a cloth on his family's estate somewhere of him after graduating from a naval education program ready to join the military when he was younger. Influenced by Dutch Masters and those classic noble and Revolutionary War era portraits. Much less colorful than my normal style, and I stayed fairly precise instead of wild. Lots of rendering. Rare that I paint indoor scenes atmospherically. There's a few things I see room for improvement on- the hand doesn't look like it's really resting on the globe properly, the attachment of his goatee to his chin and lower lip, the anatomy of his hand on the fancy schmancy cane...but overall I'm very pleased with the composition and colors. Probably open for comissions in this style if anyone wants, DM me for details if you're interested.

Alt: A somewhat short and stocky blond man with a goatee, one hand on a cane, the other on a globe, staring intesely to the right into the distance in a moodily lit brown room. In the background are a small flame chandalier, a passage to a hallways with a flower bouquet on a table in a blue vase by a painting, and a large bookcase with many tomes, an animal skull, a glass, a ship in a bottle, and a model ship with orange fan sails. The table with the globe is covered in a white draping cloth and also carries a pot of ink, a velu or parchment weighted down by a stone, a sextant, a pocket telescope, a stamp for wax seals, and a compass. The nobleman is dressed in fine brown clothes with white gray ruffles and a blue sash. He wears a gold medallion on a red ribbon around his neck, and his brows are furrowed.

Any genre of game can have a disabled protagonist if you aren't a coward / willing to put the work in, but I'm currently batting around the concept of specifically point-and-click puzzle adventure games with a highly disabled protagonist.

Often, the pace of such games tends sedate and contemplative. Your character is seldom in a hurry; they are mostly faced by trying to figure out how to accomplish a particular task, and if a deadline is imposed, it's an extra thing to juggle.

This could be an interesting presumption to incorporate from a watsonian lens, through the viewpoint of a protagonist who may have limited mobility, pain and/or fatigue that make hurrying punitively inaccessible. It'd let the player familiarize themselves with early puzzles if the first thing they have to figure out how to do is say, get their player character out of bed in an environment where they don't have their usual fallbacks.

(also if this is also a walking adventure, it'd let you dodge accusations of the insurmountable waist-high fence- your intrepid hero MIGHT be able to climb over those bricks if they didn't have two bad hips and a walker to worry about!)

Le compas est un instrument de navigation qui donne une référence de direction (le nord) sur le plan horizontal et permet ainsi la mesure d'angles horizontaux par rapport à cette direction. Le compas est gradué de 0° (nord) à 359° dans le sens des aiguilles d'une montre (sens rétrograde).

Les boussoles utilisées par les armées utilisent aussi d'autres systèmes de graduation (voir grade, appelé aussi gon, millième). La différence entre une boussole et un compas réside dans le fait que dans une boussole, l'aiguille aimantée se déplace devant un cercle gradué, tandis que dans un compas, un cadran est solidaire de l'aiguille aimantée et se déplace devant un repère.

Learn the Difference

Astrolabe vs. Armillary Sphere

Both scientific instruments provide information about the position of stars through the course of a year, however, they are dramatically different objects. The astrolabe works by projecting the night sky into a flat 2D circle, while the armillary sphere is a round object.

This is a common misconception for artists to make. Astrolabe is perhaps the most recognizable word, but very often it is used in the place of an armillary sphere (see Magic example below)

The easiest way to tell them apart is that an astrolabe is typically a flat instrument and armillary spheres are round and hollow to accommodate the rotation of the celestial sphere

3D astrolabes have existed, at least in historical texts, but they are far more rare and are not hollow

Back from concert!! It was awesome!!!

I sat next to a guy named Phil who gave me a Rob Zombie poster he'd bought but didn't end up wanting (said his wife wouldn't appreciate him hanging it in the house)

It was nice of him, but it's added one more to the weird trend I've noticed throughout my life of People Just Giving Me Stuff

The COVID-19 outbreak in the year 2020 was expected to have a negative impact on the guide extension catheter market. This is due to the decrease in the number of coronary surgical procedures. Both coronary angiography and PCI volumes decreased by 64.0% in April 2020 as compared to April 2019 according to NCBI in 2021. However, due to the ease of restriction, countries have resumed elective procedures, suggesting that the market will keep growing during the forecasted period. These qualities are anticipated to create lucrative market growth opportunities.

CVDs have become one of the major causes of mortality and morbidity worldwide during the last three decades. As per the CDC in 2021, heart disease is a leading cause of death in both sexes and members of the majority of the racial & ethnic groups in the U.S. Moreover, CVD claims 1 life every 34 seconds in the U.S. Guide extension catheters increase guide back-up support and are crucial in complex PCI procedures. Thus, increasing cases of CVDs globally are anticipated to drive the number of cardiac catheterizations, angioplasty, and Percutaneous Coronary Intervention (PCI), thereby contributing to the market growth.

Moreover, technological advancements in guide extension catheters can support professionals in identifying patients with a high risk of disease which is anticipated to stimulate market growth. For instance, in May 2019, Medtronic announced the launch of Telescope (TM) Guide Extension Catheter, a newly designed catheter to provide additional backup support and access to distal lesions. As a result, the market is expected to grow during the forecast period.
