DEF

A small oval shining black flea beetle (Epitrix cucumeris) that injures the leaves of various plants.

CONT

The potato flea beetle is primarily a pest of potato but it also attacks cucumber, eggplant, pepper, tomato and such other plants as jimsonweed, tobacco, large white petunia, groundcherry and bittersweet... Feeding injury, whether by adults on potato leaves in spring or late summer, or by larvae on tubers and roots and transmission of plant pathogens, are all potential ways in which this flea beetle may reduce potato yields both in terms of quality and quantity. Adult feeding on leaves results in rounded feeding scars, 0. 1 to 5 mm in diameter, which usually penetrate through the leaf to form a hole.

CONT

L'altise de la pomme de terre attaque surtout la pomme de terre, mais aussi le concombre, l'aubergine, le poivron, la tomate et d'autres plantes comme la stramoine, le tabac, le grand pétunia blanc, la cerise de terre et le doux-amer [...] Les dégâts causés par l'altise en s'alimentant réduisent la quantité et la qualité des tubercules lorsque les insectes adultes se nourrissent des feuilles de pommes de terre au printemps et à la fin de l'été ou lorsque les larves se nourrissent sur les tubercules ou sur les racines; l'altise peut également transmettre des agents pathogènes aux plants. Les feuilles attaquées sont percées de petits trous de 0,1 à 5 mm de diamètre, et elles ont bientôt l'apparence de feuilles criblées de trous lorsque la population d'altises est élevée.

OBS

L'altise adulte est petite, car elle mesure 1,7 mm de long et 1 mm de large. Elle est noire, mais ses pattes et ses antennes sont brunes.

CONT

How to Make A Hobo Stove. Take a gallon paint can(exact size not important-experiment). Cut holes in sides of can... Throw anything combustible in and light it on fire. The air flows in the bottom hole, and the aerodynamics of the can suck the exhaust out of the top holes. This forms a vicious through draught, and the fire burns almost white hot in a strong wind! It also uses very little fuel. Fire temperature can be controlled by turning can away from the wind a bit, or by obstructing the inlet hole.

  • The Stars (Astronomy)
CONT

[Pulsars] are now regarded as representing the penultimate stage of evolution of initially massive stars, incapable(because of excess mass) of ending their life as degenerate white dwarfs, and crushed by the cataclysm of a supernova explosion to the state of a neutron core.... The ultimate stage of this evolution should be the formation of a "black hole" configuration...

Les calculs d'évolution montrent que, pour des étoiles massives, le noyau de neutrons dépasse la valeur limite de 3 masses solaires, et ces étoiles doivent donc s'effondrer et finir leur vie en tant que trou noir.
