As demand for air travel grows, airport-related emissions are increasing and airports are challenged to reduce associated environmental impacts. In response, expanded regulatory programs and global climate protection initiatives are being developed that require the aviation industry—including U.S. airports—to implement new, clean technologies and to modify operational practices to reduce emissions. One effective option for reducing the emissions associated with aircraft auxiliary power units (APUs) and d...

Barriers, berms, buildings, and natural terrain may affect the propagation of aircraft noise by shielding or reflecting sound energy. If terrain and manmade structures obstruct the line‐of‐sight between the source and the receiver, then sound energy will be attenuated at the receiver. This attenuation increases with the terrain and structures’ size and proximity to either the source or the receiver. If gaps exist in the terrain or structures, then the potential benefits of acoustical shielding will be su...

Airports must maintain a safe and efficient facility while considering environmental impacts. Though traditional environmental challenges such as noise and water quality remain, several new themes are emerging, including energy management, sustainability, resiliency, and wildlife management. Airports will need guidelines and practices to help them address these pressing issues, and the first step in the process is to identify knowledge gaps and research needs. The TRB Airport Cooperative Research Program...

Někteří badatelé tvrdí, že dějiny Židů v Číně začínají již v 6. století před naším letopočtem za dynastie Čou, k tomu však nejsou žádné archeologické či jiné materiální důkazy. Všeobecně se tak počítají počátky židovské přítomnosti až od 8. století našeho letopočtu, za vlády dynastie Tang, kdy do Říše středu dorazily první skupinky obchodníků po Hedvábné stezce a usazovali se podél ní. Dnes od 18 hodin můžete na Facebooku Reflexu sledovat premiéru speciálního hudebního pořadu Židé v říši středu. Dějiny izraleského národa a Číny jsou zajímavě propojené.

Zdá se, že pandemie COVID 19 ustupuje. Lidem otrnulo a už se objevují logické otázky, kdo zaplatí vzniklé škody nejen podnikatelům, ale i dalším subjektům. Paleta poškozených se stále rozšiřuje a není skoro hodiny, aby v mediích nevystoupil někdo z poškozených láteřící, že na něj vláda zapomněla anebo že pomoc přichází pomalu. Někdy oprávněně, někdy spíše vykutáleně.

Po nějaké době opět exhumovali prezidenta Miloše Zemana z jeho krypty v Lánech, nabalzamovali ho a poslali mezi lidi, aby ukázal, že ještě žije, a hlavně aby promluvil k národu. Tentokrát se prezident Miloš Zeman vyjadřoval k aféře, kdy měl do České republiky přicestovat ruský občan s kufříkem plným ricinu se záměrem otrávit tři regionální politiky.

Přes čtyři roky uzavřený případ nabral nečekaný spád. Tehdy měl přijít o život fotbalista Hiannick Kamba při autonehodě v rodném Kongu. Německý bulvární deník Bild však v pondělí zveřejnil informace dokazující opak. Bývalého hráče FC Schalke 04 údajně našli v Německu živého a zdravého. Falešnou smrt má patrně na svědomí exmanželka, která se tímto způsobem dostala k penězům z pojistky.
