A production system and method for manufacturing individual building blocks or panels of lightweight fiber reinforced concrete, the method consisting of generating raw materials, conveying measured ingredients, mixing ingredients in accordance with a formula of additives, fiber, cement powder, water, and specially coated and sized Expanded Polystyrene (EPS) beads, and conveying the resultant lightweight admixture through distribution into molds on casting elements, is provided. The production line for manufacturing the lightweight fiber reinforced concrete panels has a main conveyance system, material lifts, storage racks, climate controlled curing facility, yard conveyor system, cross-transfer units, return conveyor, wash station, drying station, release agent station, framework manufacturing equipment. The main conveyance system has casting elements which are designed to receive in an operable arrangement frames and molds. The formwork or frames are determined based on the design specifications shapes and sizes determined by a CAD system or such other input, be it mechanical or manual, to achieve the panel output production.

The invention discloses a high-compactness concrete product molding machine. The machine comprises a bracket I, wherein the upper end of the brake I is provided with a vacuum vibration molding device; the front end of the vacuum vibration molding device is provided with a matching quantitative feeder; the lower end of the quantitative feeder is provided with a spreading surface material distributing machine; a matching bottom material distributing device is arranged at the rear end of the spreading fabric distributing machine and on the lower side of the vacuum vibration molding device; a steel mesh automatic laying device is arranged at the front end of the bottom material distributing device and at the lower end of the spreading surface material distributing machine; the front of the steel mesh laying device is provided with a matching brick receiver. The machine has the beneficial effects that high-compactness high-strength concrete products can be produced by using a vibration compression molding principle; particularly the conventional casting process is changed, the natural stone imitation concrete products are mechanically produced on a large scale, and extremely high economic benefit and social benefit are realized; the products are more compact, higher in strength, delicate, bright and clean in appearance and can be further deep-processed into decorative concrete products.

This invention discloses a method of building concrete walls, columns and other vertical or sloped structures using a vertically oriented vibrating screed and utilization of the thixotropic properties of wet concrete. The vertical screed is a simple, inexpensive and highly flexible apparatus that may be used for a wide variety of applications that involve the applying of cementicious material in the construction of a vertical structure. By using highly thixotropic concrete, the vertical screed is able to place concrete and other cementicious materials in a vertical plane much like concrete is placed with vibrating screeds in the horizontal plane. The vertical screed's applications range from applying a thin cementicious coating to placing concrete in a vertical plane to construct a wall or column. The various configurations of the vertical screed range from a small hand held device to a much larger mechanically controlled apparatus.

A concrete dispensing apparatus is used in a manufacturing process for producing pre-cast concrete structures, which are conventionally used to form a foundation for a residential or commercial building. The dispensing apparatus includes a hopper that funnels to a discharge opening extending along the entire transverse length of the dispensing apparatus. A plurality of individually controlled gates cover the entire discharge opening for selectively controlling the length and location of the discharge opening through which concrete is dispensed. The dispensing apparatus also includes a finishing mechanism including a vibratory screed and a rotational finishing roller. The form can be moved relative to the dispensing apparatus or vice versa. A form vibrator induces a vibratory motion into the form to remove air from the dispensed concrete mixture. Operative control is accomplished through an operator control panel operable to control a hydraulic system powering the operative functions of the dispensing apparatus.

A segmented auger mechanism is mounted in the hopper of a concrete dispensing apparatus used to distribute a hydrated concrete mixture into a horizontally disposed form to manufacture pre-cast concrete structures, such as concrete wall panels used to form a foundation for a residential or commercial building. The auger mechanism is formed of connected segments that can be individually and independently removed from the concrete structure for service and repair. The auger is rotatably supported by a pair of end bearings supported on the opposing end walls of the hopper of the dispensing apparatus, and by at least one interior bearing rotatably supporting a jack shaft having opposing half-round connecting portions for attachment to a corresponding connecting portion on the auger shaft. Removal of a segment of the auger mechanism facilitates the removal of the entire auger mechanism to minimize the down time of the concrete dispensing apparatus.

The first COPD biennial organized by the French Society of Respiratory Diseases (SPLF) took place on 17 December 2021.The objective of the biennial was to discuss current knowledge regarding COPD pathophysiology, current treatments, research development, and future therapeutic approaches.The different lecturers laid emphasis on the complexity of pathophysiologic mechanisms including bronchial, bronchiolar and parenchymal alterations, and also dwelt on the role of microbiota composition in COPD pathenogenesis. They pointed out that addition to inhaled treatments, ventilatory support and endoscopic approaches have been increasingly optimized. The development of new therapeutic pathways such as biotherapy and cell therapy (stem cells…) call for further exploration.The dynamism of COPD research was repeatedly underlined, and needs to be further reinforced, the objective being to "understand so as to better innovate" so as to develop effective new strategies for treatment and management of COPD.

La pandémie de COVID‑19 a été particulièrement mortelle pour les personnes âgées habitant en centres d’hébergement et de soins de longue durée (CHSLD) et résidences pour aînés (RPA) du Québec. Conséquemment, plusieurs gestionnaires et membres du personnel ont été confrontés au décès de résidents. Malgré cela, leur expérience des soins de fin de vie et du deuil dans ce contexte reste méconnue. Cette recherche qualitative se fonde sur les témoignages de trois gestionnaires et quatre membres du personnel ayant travaillé en CHSLD et en RPA lors de la pandémie. Ceux-ci révèlent que la pandémie a ébranlé les pratiques de fin de vie et entourant le deuil. Elle a engendré une tempête émotionnelle, et certains utilisent la métaphore de la guerre pour décrire leur expérience. Des sentiments d’impuissance et de confusion sont rapportés alors qu’un élan de solidarité et de collaboration est aussi observé. Des suggestions de pratiques pour soutenir le personnel et les résidents en contexte de fin de vie et de décès sont explorées.
