Clayton County Police Department K9 Lakota
2013 American Humane Association Law Enforcement Hero
October 3, 2011 started like any other day on the force for Clayton County Police officers Travis Fox and his partner K9 Lakota. But fate would test their fortitude and turn that day's patrol in to an unforgettable one. While responding to a call of a home invasion Officer Fox and Lakota were involved in a serious automobile crash. The force of the accident tore their patrol car in two, ejecting Officer Fox through the windshield and ripping K9 Lakota from the twisted metal that was once his travel crate. K9 Lakota and Officer Fox served together as a certified full service, dual purpose K9 team for nearly four years before the accident occurred. In their short career as partners they helped apprehend over 80 suspects, performed 28 drug seizures and located $60,000 in cash, and performed numerous vehicle and property recoveries. Their service record together is the reason they were the top K9 team to be called in response to burglary attempts.
A full service, dual purpose K9 team is trained in multiple areas:
criminal tracking
criminal apprehension
area and article searches
narcotics detection/and or explosives detection
These tasks are needed and performed during patrol work so it is vital for police
K9's to excel in these areas. They are required to assist with building and perimeter searches, suspect and criminal apprehension and other tactical operations. If you're a criminal and you've had the unfortunate altercation with a police K9, then you most vividly remember a police K9 for their bite work. The snarling, teeth-bearing German Shepherd pulling ahead taut on the leash. It's standing on its hind legs barking and trying to thrust forward, focused on its target and ready to attack. Then three loud verbal K9 warnings: "Come out now or I send the dog in and you're going to get bit!" If at this point you have not complied, you're likely to be visited by an EMS crew and recording photographer within a short time.
K9 Lakota and Officer Fox spent much of their time supporting local law enforcement agencies during suspected robberies. During one investigation, Officer Fox and K9 Lakota responded to a burglary at an auto collision business. It was believed multiple suspects were pinned down within the business' parking lot or building when earlier officers arrived, preventing the suspects from fleeing. As Officer Fox and Lakota entered the parking area, Officer Fox gave three loud and clear K9 announcements that indicated if the suspects did not surrender the police dog would be set loose to "assist" in the surrendering process.
"He has me!"
When Officer Fox heard no response he gave Lakota the command to "track." Lakota's tracking began near a bag left by the suspects beside a hole that was made in the fence to gain access to the business. Lakota caught the suspects scent and started a focused track within the yard. Officer Fox again gave a K9 warning. No response. Lakota caught a strong scent and pulled Officer Fox to one end of the lot to a car with a door that was still ajar. Lakota searched the car but quickly came back out. He then began circling the perimeter of the vehicle more feverishly. At this time, Officer Fox had noticed a window on the nearby building the car was parked by and thought perhaps the suspect climbed on top of the car and entered the structure. There was no business owner or manager on location at the time so officers were not able to access the building to begin searching. Suddenly, Lakota abruptly stopped circling the vehicle and planted himself at the front of the car. Lakota then swiftly crawled under the vehicle until all that was visible was his tail. Then, there were the screams. "He has me!" Officer Fox ordered the suspect out from under the car and removed Lakota so the other officers could take over.
K9 Lakota is a Czech shepherd, a breed originally employed as state working dogs in the Czech Republic. The Czech shepherd is larger and stockier but with a lighter bone structure than the more recognized German Shepherd we are familiar with here in the U.S. Their high level of working and pain endurance make them an ideal protection and law enforcement K9. Their large blocky heads also come in handy when taking down and detaining suspects.
"He was going to get bitten if he did not come out."
In the early morning hours of spring, Officer Fox and K9 Lakota responded to another burglary at a business. The officer who called in the request for K9 backup was responding to a silent alarm that was triggered when the suspect gained access to the business. When the officer located a hole that was cut in the fence, he saw a man run from behind the building and in to the nearby woods. The officer yelled to the suspect that a K9 unit was on its way and he was going to get bitten if he did not come out. Immediately after arriving, Lakota picked up an air scent and headed straight for the tree line where the suspect had entered. Officer Fox stopped Lakota and yelled out the K9 warnings. After no response, Officer Fox and Lakota continued along the border of the woods when Lakota began indicating he was on strong signs of a scent. Officer Fox repeated the K9 Warning. Still there was no response. Suddenly, Lakota wanted to enter the wooded area but it was thick with vines and brush. Officer Fox became tangled up in the thicket as Lakota charged ahead. Lakota was already deeper in the woods when Officer Fox heard the suspect make a grunting noise. As he pulled the last of the vines away from his body and lifted his flashlight in the direction of the sound, he saw Lakota had engaged the suspect on the head. Officer Fox gave the command to the suspect to show his hands which the suspect quickly complied. Once it was clear the suspect was not in possession of any weapons, Lakota was given the command to release. A visit from the EMS team and a trip to a medical center for treatment will remind this suspect to comply to K9 warnings if he ever hears them ordered again.
"Lakota had him by his thigh"
Lakota's love of working showed in his ability to multi-task – in bitework. One warm July day, Officer Fox responded to an assault and attempted robbery call. The first responding officer indicated she saw two suspects running towards a car wash. Lakota was deployed while Officer Fox gave three loud and clear K9 warnings. As he and Lakota were clearing the car wash parking lot, Officer Fox spotted one of the suspects lying on the ground. When the suspect saw Lakota he jumped up and attempted to flee. Officer Fox quickly gave two warnings to stop or he would release the dog. The suspect continued running so Officer Fox gave Lakota the "apprehend" command and released Lakota's leash. The suspect ran across the road and down over a hill but Lakota was fast on his heels. As Officer Fox made his way across the road and to the top of the hill he found the suspect at the bottom of the hill attempting to fight off Lakota. Lakota had him by his thigh. Officer Fox yelled commands to stop fighting the dog and to get on the ground. After a few moments, the suspect complied but kept reaching down with one hand to Lakota's head which was still secured to his leg. Officer Fox yelled and commanded the suspect to show his hands. As Lakota kept his firm grip, Officer Fox saw why only one hand was visible. Lakota not only had the suspects thigh clamped in his jaws, he also had the suspect's left hand. After the suspect raised his one available hand, Lakota was called back to release and the suspect was detained by responding officers.
After the first suspect was handcuffed and on his way for treatment by EMS, Officer Fox returned to the original tracking points to begin looking for suspect number two. While beginning the search, they heard a call over the radio that the remaining suspect had run towards a nearby apartment complex. Officer Fox and Lakota immediately proceeded to the apartment complex and Lakota was ordered to track. As the two entered an area that was encompassed by bushes, Officer Fox gave the K9 warnings. No response. Lakota was released with the apprehend command. Officer Fox had only taken two steps towards the bushes when he heard the suspect screaming that the dog had him. After removing Lakota from the suspect, responding officers were able to handcuff and bring the offender over to EMS for treatment, where he met up with his fellow cohort also being treated for bite wounds.
Many officers will tell you: K9 patrolling is not always a clean job. In the early morning hours of September 29, 2011, K9 Lakota and Officer Fox responded to a multi-alarm incident. They had been advised by dispatch that the main maintenance shed was the origination for of the alarm triggered first. As the team began tracking the fenced area, Officer Fox noticed a garage door that had been forced open. Lakota was given the command for tracking when suddenly a tall male with a dust mask peered out from the opened garage door. Immediately, the commands to surrender were given but the suspect pulled the door closed again and fled through the building. Officer Fox pulled the door ajar again and released Lakota into the building to track. Once inside, Officer Fox had to use his flashlight and observed Lakota giving a strong alert at another door at the back of the building. The door was locked and sounds of attempts to escape through walls or other entries by the suspect could be heard. As other officers arrived on the scene, Officer Fox made sure there were units surrounding the area where the suspects were trapped. He then loudly advised the suspects that if they surrendered, he wouldn't send in the dog to find and bite them. Immediately the suspects responded and indicated they were coming out. While responding officers were handcuffing the suspects, Officer Fox realized that his boots and pants were covered in yellow and gray paint that had spilled in the subsequent chase. Lakota shared in the colorful new uniform with yellow paint on his paws, back legs and tail. Soon, the strength of this Czech shepherd was truly tested, and this yellow paint would be a poignant reminder that this apprehension was Lakota's last.
Just a few days later in the early morning hours of October 3, Officer Fox and K9 Lakota were en route to a report of an armed home invasion and property theft. Since the reports indicated the suspects were a severe threat to the public, a "high speed sweep" was necessary. Law enforcement officers are expert drivers and know the limits of their police vehicles. Sometimes, however, there is no way to recover maneuverability when there is a vehicle malfunction. As Officer Fox was travelling at an emergency speed, the rear tire blew sending the cruiser out of control. The vehicle went through a fence and then struck a tree at high speed. The impact of the collision propelled Officer Fox through the windshield and Lakota out through the rear.
When he regained consciousness, Officer Fox was unaware of the condition of Lakota or his vehicle. It wasn't until the next morning his stunned family realized how devastating the crash was. The vehicle had been sheared in two.
Lakota had been thrown from his transport carrier that was in the back seat of the vehicle. It now stood twisted and mangled among what was left of the front end of the police cruiser. Lakota suffered from multiple fractures and internal bleeding. At one point, doctors believed Lakota would need one of the legs amputated due to the severity of his injuries. In all, Lakota sustained three broken legs, cracked ribs, and a fractures to his back. He wasn't expected to survive.
Lakota was immediately transported to the University Of Georgia College Of Veterinary Medicine. There, a team led by Dr. Scott Rose began the swift evaluation of Lakota's injuries to determine where to begin. Lakota was in critical condition and needed to be stabilized before undergoing any surgical procedures. After radiographs showed where the leg fractures needed splinting, Dr. Rose's team prepared Lakota for the first of many surgeries to save his life. On October 7th, Lakota's first surgery to repair his damaged back legs lasted over 5 hours. The surgeries were a success; Lakota's damaged legs were placed in casts, and he began the long and arduous healing process.
Officer Fox sustained multiple broken ribs and lacerations over his entire body but the pain of being separated from his K9 partner was immense. For 8 days, they could not see each other while both Lakota and Officer Fox were in recovery. On October 11th, the Fox family was finally able to visit Lakota in the ICU for a sweet reunion. Officer Fox was visibly emotional but happy to be with his partner.
Some spouses might be jealous or offended by the amount of attention a handler gives to their K9 partner. Officer Fox's wife, Corey, doesn't mind at all. Matter of fact, she knows how important the bond between handler and K9 really is. Their youngest child has an autism and seizure alert service dog so they know the importance of the bonds that K9 teams form. Together, Travis and Corey operate a family business, Guardian of the Night K9, a company that specializes in training service and working dogs. With Officer Travis Fox's background in K9 law enforcement and years of work with ADA service dogs, creating and understanding the bond between K9 and handler comes natural to them.
The costs of Lakota's treatment and recovery weighed heavily on the family. When the accident happened, Officer Fox learned that his department was planning on immediately retiring Lakota due to his wounds. Because of his injuries, Lakota would end up in a shelter, or worse, because of the expense of his treatment, be euthanized. So Officer Fox immediately stepped up and offered to adopt Lakota and be responsible for his care. Luckily, members of the Clayton County Commissioners Office and police officials announced that the county would cover the cost of Lakota's surgery and treatment. It was estimated to cost nearly $10,000 though that didn't include expenses during the long-term rehabilitation Lakota would permanently require. However, if the county had not stepped up to cover those initial medical bills, the costs would have been financially devastating for the family. The Fox family realized this glitch in the working dog world needed to be addressed; many handlers would not be able to afford that kind of money, nor would they want to lose their K9 partners.
During the 2013 American Humane Association's Hero Dog Awards, K9 Lakota won the Law Enforcement/Arson Dog category. Officer Travis Fox and K9 Lakota were sponsored by State Farm Insurance which supports the Law Enforcement officers and teams. The family was flown to Beverly Hills to be present for the crowing of the "Top Dog" winner during the televised event hosted by the Hallmark Channel. After the awards show was televised, Corey Fox contacted our project to nominate K9 Lakota for one of our hero portraits.
K9 Lakota passed our program requirements easily and in July of 2014 I began working on his portrait. Since the Fox family was aware of the portrait nomination and acceptance, I was allowed to show progression photos on Facebook for ours and K9 Lakota's fans to see.
On September 17th, Lakota's portrait was shipped and had arrived to the Fox family. Corey Fox had filmed Travis unwrapping and seeing Lakota's portrait for the first time in person. In minutes, the portrait was already hung on the wall they prepared the week before the painting was even completed.
Sometimes our project donates proceeds or sets up fundraisers for some of our portrait recipients. Law enforcement K9 units normally don't cover additional expenses for the teams and the money comes direct out of the handler's pocket. For Lakota, we learned the extent of his injuries were so severe that he needed permanent physical therapy to keep his joints and muscles flexible. Their veterinarian recommended a canine treadmill which would be beneficial especially in the cold winter months when physical activity would be limited outdoors. The K9 Hero Portrait Project quickly contacted DogPacer treadmills and created a fundraiser for K9 Lakota. In just a few days, and with the final boost from State Farm Insurance, we raised enough money for not only the treadmill, but also a Sealy Orthopedic dog bed. Lakota received not only the treadmill, but also a wonderful spot to relax after a long physical therapy session.
After being together for another four years, this hero was given a respectful fairwell and last ride. Lakota's family will always remember everyone who supported them during Lakota's life.

after downloading song sending notification from another view to table view

           NSLog (@"Successfully received the test notification!");

    // Perform long running process
       [self  updateDownloadList];
       [[AlbumsAnsSongs sharedManager] getallFiles];
       [_tableView reloadData];
   }
 }

A: Since problem is with UI update so I guess when your data completes downloading you should call reloadData method like this:
 - (void) receiveTestNotification:(NSNotification *) notification
{
   if ([[notification name] isEqualToString:@"TestNotification"])
         {
           NSLog (@"Successfully received the test notification!");

    // Perform long running process
       [self  updateDownloadList];
       [[AlbumsAnsSongs sharedManager] getallFiles];

       dispatch_async(dispatch_get_main_queue(), ^(void){
            [_tableView reloadData];
        });

   }
 }

Another problem that seems to be there is that you are removing the button with this statement
[cellMain.playButton removeFromSuperview];

but in else part you are not adding the button back,
I think instead of removing playButton you should hide the button
cellMain.playButton.hidden = YES

and then in else part
cellMain.playButton.hidden = NO

Explanation:
You were removing the button from cell, since the cells are dequed or you can say reused , cells without button were being displayed on the screen

Radar (pokrata ili akronim od eng. Radio Detection and Ranging: otkrivanje i određivanje udaljenosti radio valovima) je elektronički uređaj za određivanje udaljenosti, azimuta, elevacije (kutna visina) i brzine nekog predmeta na temelju odbijanja (refleksije) iz uređaja emitiranih elektromagnetskih valova od taj predmet. Prvi uređaj izradio je oko 1900. njemački izumitelj Christian Hülsmeyer, a predložena je njegova primjena u sprječavanju sudara brodova. Razvoj ratnoga zrakoplovstva, posebice teških bombardera, potaknuo je razvoj radara jer je trebalo razviti uređaj za rano upozoravanje na dolazeću opasnost. Prvi uređaj u osnovi istovjetan današnjim radarima izradio je Robert Watson-Watt (1935.).

Radar omogućuje otkrivanje predmeta u uvjetima loše i smanjene vidljivosti, na primjer u mraku, kroz dim, maglu, kišu ili snijeg. Kako se elektromagnetski valovi šire pravocrtno, raspon (domet) je radara ograničen zakrivljenošću Zemljine površine, pa na primjer u kontroli zračnoga prometa iznosi oko 400 kilometara. Veći raspon (više tisuća kilometara) ima jedino radar koji koristi odbijanje (refleksiju) valova na ioniziranim slojevima atmosfere (ionosfera). U ratu je radar stekao izvanrednu važnost, a u mirnodopskoj se primjeni ističe njegova uloga u sigurnosti pomorskoga, zračnog i cestovnoga prometa.

Prve upotrebljive radare imali su Britanci na početku Drugog svjetskog rata. Pomoću radara lakše su pratili nalete njemačkih aviona, te lakše organizirali obranu. Moderni radari se koriste u zrakoplovstvu i pomorstvu za traženje ciljeva, ali i u astronomiji kod proučavanja površine dalekih planeta. U današnje doba radare koristi i policija za određivanje brzine vozila.

Radari imaju važnu ulogu u pomorskoj i zrakoplovnoj navigaciji. Ima radarskih sistema koji na zaslonu katodne cijevi daju obrise (konture) predmeta koji se nalazi ispred brda odnosno zrakoplova. Na taj se način mogu izbjeći sudari na moru s ledenim santama i drugim brodovima kada prijeti opasnost zbog magle.

Način rada
Radar je uređaj koji služi za otkrivanje prisutnosti teško uočljivih ili posve nevidljivih predmeta i za otkrivanje njihove udaljenosti. Način rada radara osniva se na svojstvu ultrakratkih elektromagnetskih valova, koji se šire pravocrtno, pa se mogu reflektirati od krute odnosno metalne površine. U tu svrhu upotrebljavaju se decimetarski ili centimetarski valovi. Kao predajnik služi parabolični reflektor, koji se može okretati na sve strane, a u svom žarištu ima takozvanu mikrovalnu antenu. Na tu antenu dovode se ultravisokofrekventne struje, koje se u obliku kratkotrajnih električnih impulsa šalju u uskom snopu u prostor. Ti se impulsi šalju u vrlo kratkim vremenskim razmacima oko 1000 puta u sekundi. Ako ti impulsi naiđu na neku zapreku, oni će se odbiti, pa će ih antena odbiti. Primljeni električni impulsi odlaze u prijemnik i šalju se na optički indikator, koji je katodna cijev. Iz vremenske razlike od polaska do povratka impulsa dobije se udaljenost predmeta. Katodna cijev je tako konstruirana da u trenutku kada s radarskog reflektora odlazi impuls u prostor elektromagnetska zavojnica svojim magnetskim poljem pomakne katodnu zraku, a time i svijetlu točku na zaslonu uvis. To se isto dogodi kada se vrati reflektirani val. Vremenski razmak prikazan na katodnoj cijevi kao duljina je mjera za udaljenost predmeta.

Radar radi na načelu radio valova, kako je već prije i spomenuto. Antena odašilje kratki impuls, koji se odbija od cilja. Na temelju vremena koje je proteklo do povratka zrake izračuna se udaljenost od objekta. Današnje moderno ratno zrakoplovstvo koristi stealth tehnologiju koja avione čini praktički nevidljivima radaru. To postižu tako kad valovi idu prema objektu, on zbog posebnih materijala i posebno dizajniranih oblika raspršuje radarske radiovalove i tako ostaje neotkriven. Na taj način imaju prednost neopaženog dolaska do cilja.

Dijelovi radara
Radar se sastoji od antene, radioodašiljača, radioprijamnika i računala za obradu i prikaz podataka. Ako su odašiljač i prijamnik postavljeni na različitim mjestima i imaju zasebne antene, radar je bistatički, odnosno multistatički ako ima više odašiljača i prijamnika. Odašiljač i prijamnik mogu se nalaziti i na istome mjestu, odvojeni takozvanim duplekserom, koji im omogućuje da se ista antena koristi za odašiljanje i prijam elektromagnetskih valova (takav se radar naziva monostatičkim). U početku su radari većinom bili bistatički zbog nemogućnosti postizanja dovoljne izolacije između odašiljačkih impulsa velike snage (i do nekoliko megavata) i prijamnika velike osjetljivosti kakva je potrebna za prijam reflektiranoga vala vrlo male snage (10–13 do 10–14 W). Razvojem dupleksera s dovoljnom izolacijom i mogućnošću brzoga prespajanja ti su nedostatci uklonjeni. Danas su radari većinom monostatički, ali se važnost bistatičkih i multistatičkih radara ponovno povećala zbog njihove mogućnosti da lakše i sigurnije opaze takozvane nevidljive zrakoplove.

Odašiljač zrači elektromagnetske valove kao niz kratkih impulsa u trajanju reda veličine mikrosekunde, a impulsi se ponavljaju nakon 1 do 50 ms. U razdoblju između odašiljanja dvaju uzastopnih impulsa prijamnik prima odjeke koji nastaju refleksijom odašiljačkih impulsa od predmeta u promatranom prostoru. Kako bi se omogućilo promatranje (pretraživanje) cijeloga prostora u okolini radara, antena se najčešće mehanički zakreće po azimutu i/ili elevaciji (kutnoj visini). Umjesto zakretanja cijele antene, može se elektronički zakretati samo glavni snop zračenja antene, što omogućuje znatno veće brzine promatranja prostora.

Udaljenost predmeta
Udaljenost R predmeta (cilja) od radara određuje se na temelju vremena t potrebnoga da elektromagnetski val prijeđe put od radara do predmeta i natrag:

gdje je: c - brzina svjetlosti. Kutne koordinate predmeta (azimut i/ili elevacija) određuju se iz smjera u kojem je postavljen glavni snop zračenja antene u trenutku prijama odjeka. Znatno veća točnost određivanja kutnih koordinata postiže se primjenom prijamne antene s više istodobnih glavnih snopova zračenja i međusobnom usporedbom tako dobivenih signala (takozvani monoimpulsni radar).

Dopplerov učinak

Brzina predmeta (na primjer cestovnoga vozila) određuje se iz Dopplerova pomaka frekvencije signala odjeka u odnosu na frekvenciju odaslanoga signala. Dopplerov se pomak frekvencije određuje iz razlike faza između više signala odjeka u nizu, koji su primljeni od istog predmeta. Prikupljeni podatci se digitaliziraju, obrađuju u računalu i prikazuju na zaslonu. Brzina i smjer kretanja predmeta mogu se prikazati dodatnim vektorom brzine pridruženim svakom predmetu na zaslonu. Takvu se prikazu mogu dodati i zemljopisna karta promatranoga područja, opis pojedinog predmeta (određivanje ili identifikacija, udaljenost, brzina) i drugi podatci značajni za specifičnu primjenu pojedinoga radarskog sustava.

Frekvencijsko područje radara
Frekvencijsko područje radara ovisi o njegovoj primjeni, a nalazi se u rasponu od približno 10 MHz do 100 GHz. Na najnižim frekvencijama rade radari za promatranje iza obzora refleksijom valova od ionosfere; u području od 100 MHz do 2 GHz, zbog malog utjecaja atmosfere na valove tih frekvencija, rade radari velikoga dometa za nadzor zračnoga prostora; u području od 2 do 8 GHz rade radari za točnije određivanje položaja, za promatranje srednjeg dometa, za praćenje te za gađanje većega dometa. Na frekvencijama od 8 do 12 GHz radi najveći broj zrakoplovnih, meteoroloških, brodskih i navigacijskih radara, jer to frekvencijsko područje omogućuje primjenu poluvodičkih izvora male mase i izmjera te primjenu relativno malenih antena velike usmjerenosti. Na još višim frekvencijama rade radari za posebne namjene te eksperimentalni sustavi (na primjer radari za svemirska istraživanja (radio astronomija), radari na cestovnim vozilima i slično).

Primjena radara
Među najvažnijim je područjima primjene radara kontrola zračnoga prometa, u kojoj se koriste promatrački radari velikoga dometa (oko 400 km) i radari koji nadziru prilaz pojedinoj zračnoj luci (domet nekoliko desetaka kilometara). U kontroli zračnoga prometa koristi se i radar s aktivnim odjekom (sekundarni radar), koji ne djeluje na načelu jednostavnog odraza elektromagnetskoga vala od zrakoplova, nego se primjenjuje poseban uređaj na zrakoplovu (takozvani odgovarač), koji šalje povratne impulse kada se pobudi impulsima sa zemaljskoga radara i omogućuje prijenos dodatnih informacija (na primjer određivanje ili identifikacija zrakoplova). Sekundarni radar razvijen je za vojne potrebe, s namjerom da se omogući razlikovanje vlastitih od neprijateljskih zrakoplova, a danas je on značajna podrška kontroli civilnoga zračnog prometa. Iako je sekundarni radar zapravo radiokomunikacijski sustav s automatskim odgovaranjem, uobičajeno se svrstava u radarske sustave.

Navigacijski radari
Navigacijski radari manjega su dometa (do 100 kilometara) i značajna su pomoć posadi pri upravljanju brodovima i zrakoplovima u uvjetima smanjene vidljivosti i (ili) gustoga prometa. Slični se radari postavljaju u zračnim i pomorskim lukama te uz plovne puteve i služe za nadzor prometa.

Meteorološki radari

Meteorološki radari rade u više frekvencijskih područja, jer se zbog različite reflektivnosti na različitim frekvencijama može dobiti znatno više meteoroloških podataka. Služe za određivanje (lociranje) područja oborina i oblaka u atmosferi i njihovo gibanje, za određivanje vrste i jakosti (intenziteta) oborina (kiša, snijeg, tuča i drugog), strukture oblaka, za dobivanje trodimenzijske slike područja te utvrđivanje područja turbulencije i moguće opasnosti za predmete na tlu i u zraku. Meteorološki radari rade na valnim duljinama od 1 do 20 centimetra, s odaslanom snagom od 100 do 1000 kW i dosegom od nekoliko desetaka do više stotina kilometara. Dopplerov radar djeluje na načelu Dopplerova učinka i omogućuje mjerenje poprečne (radijalne) brzine ciljeva u atmosferi (oborinskih čestica, čestica prašine) koji se gibaju izravno prema radaru ili od njega. Neke vrste radara koriste se kao vjetreni presječnici za dobivanje okomitog profila vjetra unutar troposfere. Neki radari služe i za određivanje visinskoga vjetra (praćenje radarske mete koja visi ispod meteorološkoga balona), a posebna je vrsta radara postavljena i na nekim meteorološkim satelitima za određivanje morskih valova (lidar ili optički radar).

Radari sa sintetskom antenom
Radari sa sintetskom antenom služe za promatranje površine Zemlje ili drugih planeta, a njima prikupljeni podatci nalaze primjenu u agronomiji, šumarstvu, rudarstvu, arheologiji, meteorologiji, zemljopisu, oceanografiji, ekologiji, razminiranju, astronomiji i tako dalje. Njihova je antena postavljena na pokretni predmet (zrakoplov, umjetni satelit, upravljivi balon) koji se kreće stalnom (konstantnom) brzinom iznad ili uzduž promatranoga područja. Računalnom obradbom podataka prikupljenih promatranjem uz više uzastopnih položaja antene dobiva se slika promatranoga područja visoke razlučivosti, koja djeluje kao da je dobivena antenom znatno većih izmjera od stvarne antene. S obzirom na to da je ta zamišljena (virtualna) antena rezultat računalne obradbe, ona se naziva i sintetskom antenom pa odatle potječe i naziv te vrste radara.

Radari u vojništvu
Vojna primjena radara slijedila je ubrzo nakon njegova izuma. Tako je Velika Britanija od 1936. do 1939. postavila uzduž južne i istočne obale lanac radarskih postaja za obranu od njemačkih zračnih i pomorskih napada, a SAD je do 1940. počeo proizvoditi impulsne radare za praćenje zrakoplova i nadzor vatre protuzračnih topova. Ubrzo su se užurbanom razvoju i vojnoj primjeni radara pridružili Njemačka, SSSR i Japan. Premda je najprije služio u mornarici i zrakoplovstvu, danas se radar snažno koristi u svim granama oružanih snaga. Najčešće su uporabe u protuzračnoj obrani, proturaketnoj obrani, prikupljanju obavještajnih podataka te nadzoru vatre različitih oružanih sustava, od topništva, do tenkova, zrakoplova i brodova. Suvremeni bojišnički radari otkrivaju i prate kretanje vozila, ali i pojedinačnih vojnika na bojištu. Složenost suvremenih oružanih sustava zahtijeva istodobno korištenje više radara različitih parametara, od kojih svaki ima posebnu zadaću (na primjer na suvremenom ratnom brodu to je navigacija, pretraživanje površine mora, pretraživanje zračnoga prostora, određivanje visine cilja, nadzor vatre). Danas je u središtu istraživanja razvoj radarski vođenih projektila te radara za rano otkrivanje, praćenje i uništenje raketa s nuklearnim bojnim glavama.

Gaelic Language learning Bursary (Scotland)
Gaelic Learning Directorate, Scottish Government & Gaelic Affairs, a Division of the Department of Communities, Culture and Heritage
In an effort to support Gaelic language acquisition and use, the Scottish Government established a Gaelic studies bursary program.
This bursary program is designed to support Nova Scotia, Canada based Gaelic students with travel, meals and accommodation costs in Scotland while working on acquiring and using Gaelic language and culture.
This bursary program supports the mandate of Bòrd na Gàidhlig (Scotland) that includes support for Gaelic language learning outside of Scotland.
This bursary is designed to support the objective of the Gaelic Council of Nova Scotia, the Gaelic Community and Gaelic Affairs, a Division of the Department of Communities, Culture and Heritage to create more fluent Nova Scotia Gaelic speakers.
The National Center for Cultural Competence, Washington, DC, defines culture as an
"integrated pattern of human behaviour that includes thoughts, communications, languages, practices, beliefs, values, customs, courtesies, rituals, manners of interacting and roles, relationships and expected behaviors of a racial, ethnic, religious or social group; and the ability to transmit the above to succeeding generations" (Goode, Sockalingam, Brown, & Jones, 2000).
This means that language is both part of how we define culture and how it also reflects culture.
With this cultural perspective in mind, applicants will enrol for a minimum of two weeks in a Gaelic medium short course at a Gaelic institution such as Sabhal Mòr Ostaig (SMO), Scotland. With the assistance of Gaelic Affairs and Gaelic Scotland counterparts, applicants will include as part of their language acquisition and use a focus on a specific Gaelic dialect that is of interest to them and meet, visit and interview a native Gaelic speaker in Scotland that uses and shares this particular dialect and/or a similar dialect. Through the medium of Gaelic, the interview will focus on the cultural competencies cited above.
Successful applicants will be awarded funding for travel, food and registration fee costs in Scotland and/or for distance learning costs.
Applicants must be permanent residents of Nova Scotia.
Applicants must be 18 years of age or older.
Applicants must provide a detailed letter outlining their experience in and commitment to language acquisition and use in Nova Scotia.
Applicants must provide a letter of reference from a Nova Scotia Gaelic-based organization.
Applicants must provide a letter of acceptance confirming their enrollment for a minimum two week course at a Gaelic-medium institution.
Factors that will be considered when scoring the applicants will be:
Time involved in learning Gaelic
Demonstrated level of involvement in Gaelic-based organizations in Nova Scotia
Appreciation, awareness and efforts made to use a specific dialect and how you go about supporting this
How do you plan to sustain the skills you learn and apply them in your local community?
What are your future plans specific to further developing your skills to support the Gaelic cultural community in Nova Scotia, i.e. enroll in a language immersion and/or mentorship program?
Expectations upon return:
Applicants will provide an audio and/or video recording and present on their interaction with Gaelic speaker in Scotland. A minimum 45 minute presentation will be done in the applicant's local community and highlight specific aspects of language and culture acquired while enrolled in the bursary program.
Please e-mail application information to Kelly Schlay at Kelly.Schlay@novascotia.ca or mail to:
1741 Brunswick Street
P. O. Box 456, STN Central
Canada B3J 2R5
A peer assessment panel will review applications.
Deadline for applying is Friday, January 18, 2019.

This design is a demonstration of the use of skewed hyperbolic gears. Given a skew angle and distance between a pair of axes, a corresponding pair of hyperbolic shapes can be computed which exhibit line contact with each other. By augmenting these hyperboloids with involute teeth the transmission of torque between the skew axes may be achieved.
In this design, three smaller hyperbolic gears are in common mesh with a larger fourth gear, in an arrangement commonly known as a "planetary" gearset. This produces a visually exciting object which is a practical demonstration of both simple and advanced principles in the design of geared systems.
I have printed a prototype of this design and found that it functions properly. A little bit of "run-in" is necessary to produce smooth torque transmission, as there is a sliding component to the hyperbolic gear contact.
The only colors that I had available to print the prototype were quite ugly, and I would be very happy if someone could produce this design in a pleasing color scheme.
Print three of the smaller-diameter gears and a single large gear. Also print three of the connecting rods and two of the triple joints. These are assembled using #10 socket-head cap screws. The display stand may be printed, but the gearset will rest upright without it. A pair of hex keys can be used to rotate either the inner sun gear, or the frame holding the planet gears.

New record set for David Jagger painting
June 19, 2017 charlesfoster2 Comments
Pic: Bonhams
The artist David Jagger (1891-1958) was the father of Sgt Brian Jagger, who flew on the Dams Raid as the front gunner in David Shannon's crew. David Jagger's paintings seemed to fall out of fashion for a while after his death, but recently many art critics and collectors have concluded that he has been wrongly underrated and his work has been much more widely recognised. This has also been reflected in the saleroom prices achieved for his work.
Last week, a 1928 self portrait came up for sale at Bonhams in London. It had been estimated that this would fetch about £20,000 – however, when the hammer went down, it had achieved a staggering £221,000, a world record for Jagger's work. It is not yet known who bought it.
The Bonhams catalogue explains some of the background to the picture:
During the late 1920s David Jagger had established a system of artificial lighting in his Chelsea studio and had become fascinated with the chiaroscuro effects it produced. During this time he produced a small number of intimately observed portraits, of which this work is one.
Described by the art critic, Bernard James Valentine Carr in an undated exhibition review, 'To even the most casual observer, the best of the oil paintings is Mr. Jagger's Self Portrait which is a remarkably fine example of the artists' technique allied to an unusual method of presentation. The picture is a head against a very dark background. The fact of the dark background and of cutting the portrait off at the chin is to make the shape of the head, the lineaments of the features, and the general characteristics of the subject stand out with unusual force'.
The catalogue entry was written by the art historian Timothy Dickson, who has a website dedicated to information about this remarkable artistic family, Edith, Charles Sargeant and David. They were siblings, all born in Kilnhurst in Yorkshire and all educated at Sheffield Technical School of Art. Tim is writing a book about the family, and we will let you know when it becomes available.
Brian Jagger of course survived the Dams Raid, but died later in the war, on 30 April 1944, in a tragic training accident at RAF Gransden Lodge while testing a new gun turret (scroll down). He was an only child and his death was a devastating blow for his parents, David and Kitty Jagger.

David Shannon's changing crew
April 13, 2016 April 14, 2016 charlesfoster4 Comments
Plt Off Bernard Holmes, rear gunner in David Shannon's crew in 106 Squadron. Holmes completed a full tour with Shannon, and was brought to 617 Squadron at Scampton in March 1943. Three weeks later, he was transferred out. Later in the war he joined 77 Squadron and flew on 13 further operations. [Pic: Robert Holmes]
At the end of February 1943, David Shannon finished his tour of operations in 106 Squadron with a trip to St Nazaire. This was the 36th sortie in a run which stretched back to June 1942, shortly after his 20th birthday. During his tour, he had generally flown with a core crew made up of Danny Walker, navigator, Wallace Herbert, bomb aimer, Arnold Pemberton, wireless operator, Douglas McCulloch, mid upper gunner and Bernard Holmes, rear gunner. Over the course of the tour Shannon flew with a number of different flight engineers and/or second pilots, but in the last few months Sgt Cyril Chamberlain became the regular flight engineer.
An enforced change happened in November 1942, when Danny Walker came to the end of his own tour. He was posted to No 22 OTU as an instructor and thereafter a number of different navigators filled in for him. These included the experienced Norman Scrivener and Winston Burnside, both of whom also navigated for Guy Gibson in this period.
Shannon's last operation in 106 Squadron on 28 February appears to have coincided with the end of the tours of Herbert, Pemberton, McCulloch and Holmes. Under normal circumstances, the crew would have broken up and all would have been sent on instructional duties for a period of six months. Shannon, however, wanted to carry on flying and somehow arranged a transfer to 83 Squadron at RAF Wyton, a Pathfinder outfit. It was there that he got a telephone call from Gibson, asking him to join him at Scampton where he was forming a new squadron.
Chamberlain, Herbert, Pemberton, McCulloch and Holmes were apparently all still at Syerston, waiting for new postings. Consideration was obviously given to reconstituting Shannon's 106 Squadron crew, since Chamberlain, Pemberton, McCulloch and Holmes were all transferred to the new 617 Squadron at Scampton on or about 25 March 1943. Herbert appears either not to have been asked or to have declined the offer. Also, Shannon's old crew member Danny Walker was specifically sought out to fill the post of navigator, and was brought over to Scampton from No 22 OTU at Wellesbourne Mountford.
It is not clear exactly what happened next. Shannon undertook two testing flights on 28 and 31 March, but he only recorded the names of the other pilots with whom he flew (Flt Lt Dierkes on 28 March, Flt Lt John Hopgood on 31 March). His next flight wasn't until 6 April, when he did a 5 hour cross country and bombing trip. This was repeated, over a different route, two days later on 8 April. On both of these flights, a five man crew is recorded. This consisted of Walker and McCulloch, both from his 106 Squadron days, two new names – bomb aimer Len Sumpter and flight engineer Robert Henderson, plus Larry Nichols, a wireless operator borrowed from Melvin Young's crew.
After the war, Len Sumpter described how he and Henderson were recruited to the squadron. At that stage, he had completed 13 operations in 57 Squadron, based at Scampton. Then his pilot was grounded with ear trouble and the crew were broken up. He and his erstwhile crewmate Henderson knew that a new squadron was being formed in the next two hangars, and heard that Shannon was looking for a bomb aimer and a flight engineer, so they sought him out. "We looked him over and he looked us over – and that's the way I got on to 617 Squadron." (Max Arthur, Dambusters: A Landmark Oral History, Virgin 2008, p18.) No date is given for this "interview", but it must have occurred sometime between 31 March and 6 April.
Sumpter goes on to say that the crew didn't get their own wireless operator until the end of April. He didn't know – or didn't mention – that there were three members of Shannon's old crew, including wireless operator Arnold Pemberton, kicking their heels on the ground.
On 11 April, Shannon's logbook records the first flight of a new crew member, rear gunner Jack Buckley. He had been transferred from No 10 OTU, where he was working as an instructor. He was an experienced gunner and had been commissioned, having completed a full tour of operations with 75 (New Zealand) Squadron. Albert Garshowitz (misspelt as Gowshowitz) from Bill Astell's crew was the borrowed wireless operator on this occasion.
Two days later, on 13 April, a complete squadron crew list was compiled, under the title "Order of Battle". This is preserved in a file in the National Archives (AIR14/842). It shows Shannon's crew as: Henderson, flight engineer, Walker, navigator, Sumpter, bomb aimer, McCulloch, mid upper gunner and Buckley, rear gunner. The position of wireless operator is left blank. Flg Off McCulloch is also listed as A Flight Gunnery Leader. Four names are listed as 'spares', amongst whom are the other three members of Shannon's 106 Squadron crew: Pemberton, Holmes and Chamberlain.
Another two days later, on 15 April, Douglas McCulloch attended an Aircrew Selection Board. He must therefore have previously applied for remustering. However, he returned to the squadron and flew on more training flights with Shannon on 19 and 21 April. He was eventually posted to No 13 Initial Training Wing on 1 May.
On 17 April, Bernard Holmes and Arnold Pemberton's time at 617 Squadron ended, with them both being recorded as being posted to No 19 OTU at Kinloss. There is no record of the destiny of Cyril Chamberlain. Holmes's son Robert recalls that his father apparently told his wife at the time that he and Pemberton were bored and frustrated through not being kept busy, and asked for a transfer.
Eleven days later, on 24 April, another squadron crew list was published. The Shannon crew now shows two changes. The wireless operator position has been filled by Flg Off Goodale DFC and the mid upper gunner has the handwritten name of Sgt Jagger in a space which had been left blank by the typist. The A Flight gunnery leader is now shown as Flg Off Glinz (from Norman Barlow's crew). There are no longer any names listed as spares (National Archives: AIR14/842). This date coincides with Goodale's first appearance in Shannon's logbook. It is notable that Brian Jagger's name may appear here, but in fact he did not fly with Shannon until 4 May.
Both men came with a deal of experience. Brian Goodale had a completed full tour and was recruited from No 10 OTU, where Jack Buckley had also been an instructor. Brian Jagger came from 50 Squadron. He had previously flown with John Fraser and Ken Earnshaw, two Canadians in John Hopgood's crew, and they may have been instrumental in getting him on board.
On this date, David Shannon's Dams Raid crew was finally established, and they would fly together for the next few months. Quite why three members of his crew from 106 Squadron were earlier brought over to Scampton but never used remains a mystery.
Later in the war, after a spell as an instructor, Bernard Holmes returned to operations with 77 Squadron, and joined a crew skippered by Wg Cdr J D R Forbes, the squadron CO. He remained there until the end of hostilities. He had married his wife Margaret in 1940, and they had two sons, born after the war. The family emigrated to South Africa in 1952, and he died there in 1979.

Front gunner
Lancaster serial number: ED929/G
Call sign: AJ-L
First wave. First aircraft to attack Eder Dam. Mine dropped accurately but no breach caused. Aircraft returned safely.
Brian Jagger, David Shannon's front gunner, came from an artistic family. His father, David Jagger, was a well known portrait painter and his uncle, Charles Sargeant Jagger, was a sculptor and artist, and was responsible for many memorials to the dead of the First World War. His aunt, Edith Jagger, was also an artist.
Jagger was born in Chelsea on 9 November 1921 and joined the RAF in 1941. He qualified as an air gunner in the summer of 1942, and was posted to 50 Squadron. Most of his operations were flown in a crew piloted by Sgt Norman Schofield, a Canadian, in a crew which also included two other Canadians who would fly on the Dams Raid, John Fraser and Ken Earnshaw. It may have been one of these who recommended Jagger to David Shannon when he was putting together his crew for 617 Squadron.
After the Dams Raid, Jagger flew on several other operations with the Shannon crew, and was commissioned in October 1943. He was transferred to a training unit in the spring of 1944, and was killed in a flying accident on 30 April 1944, in a Lancaster of 49 Squadron. On a Fighter Affiliation Exercise, a dinghy became released and wrapped itself around the tailplane causing the aircraft to crash.
One of his father's best known paintings is known as 'Portrait of an officer of the RAF during World War II', painted in 1941, which was held in the Arthur Ackermann and Peter Johnson Collection. It came up for auction at Christies in 2008, but was unsold. Although the title says the subject is an officer, he is quite clearly wearing sergeant's stripes. The subject is not identified, but he bears a striking resemblance to Brian Jagger, and could well be of him.
Brian Jagger is buried in Cambridge City Cemetery.

what is a gene?
Frank Ackerman
For the average person trying to understand the basics of genetics, it would probably make do to think of a gene simply as a segment of DNA that determines a trait.
The term in its most abstract refers to an inherited trait. But decades of scientific research into genetic material have yielded a far more specific understanding of what a gene is and does. According to the definition in Merriam-Webster, a gene is:
"a specific sequence of nucleotides in DNA or RNA that is located usually on a chromosome and that is the functional unit of inheritance controlling the transmission and expression of one or more traits by specifying the structure of a particular polypeptide and especially a protein or controlling the function of other genetic material"
But even this rather lengthy definition is far from exhaustive and doesn't account for certain problems that scientific research is still working to resolve. For example, scientists in many cases have found it difficult to determine where one gene ends and another begins. In some cases, genes even overlap and share sequences of nucleotides. But while these details are important to work out for genetic research, they do not necessarily have implications for a fundamental understanding of genetics and a highly simplified definition should suffice.

Netify's device discovery utility identifies all devices communicating within your network in near real-time and on a continual basis. This lets you keep tabs on anything from your static, mainstay devices like desktops, printers and routers, to more "transient" devices, like smartphones and tablets, that regularly come and go from your network.
Getting a full, detailed inventory of what's on your network is not only best practice, but the first step towards understanding and managing potential cybersecurity risks from suspicious or unknown devices.
Netify's device discovery utility uses a mix of machine learning and cloud-based analytics to gather information about devices on your network.
Identifies devices on your network, such as smartphones, printers, laptops, etc.
Metadata including operating system, MAC address, MAC vendor, etc.
For example, Netify's device discovery utility can take cryptic data that doesn't tell you much – like a MAC address (00:1e:67:19:3e:f6) – and give you the visibility to see the MAC address is from a Dell laptop running Windows 10 that last communicated with your network six minutes ago.
Device discovery also lets you to tag, classify and associate devices with specific users or groups that you define.

Q: AWS efs mount permission denied I am trying to mount an efs to an ec2 instance.  I first was timing out, then created a new security group for my vpc with my ec2 instance as the source and added this to my efs.  I am now getting a permission denied.  I read that I needed to "check your file system policy and your identity policy to ensure there are no DENY clauses that apply to your connection, and that there is at least one ALLOW clause that applies to the connection."
I have not changed my security policy on the efs and it looks like the below.  I am a little lost on if I need to change anything.  I see a deny and allow clause.  Is this the source of my permission denied or is it something else?  If it is, is there information on how to edit it?
{
    "Version": "2012-10-17",
    "Id": "efs-policy-wizard-",

                "AWS": "*"

            ],
            "Resource": "arn:aws:elasticfilesystem:"
        }
    ]
}

I do not seem to have an iam policy for any efs access.  Is this my problem?  Is there information on how to create one for an efs mount?
Thank you.

A: This is a resource policy for the EFS mount, by adding the condition to deny all actions when not using TLS it will deny if you're not establishing a mount using TLS.
To do this either look at these instructions or remove the deny block, relying instead on security groups.
Additional example resource policies can be found here

A: You need to first check the mount options and policies as instructed by https://aws.amazon.com/premiumsupport/knowledge-center/efs-enable-read-write-access/
If they both look good, then test your permission by sudo. If you can write to the EFS with sudo, then you can just grant non-root users the privileges by sudo chmod 777 /your/efs/mount/point

Etihad Lays On First Class To India
New widebody and narrowbody services meet local traffic demand and boost connectivity.
by Dominic Ellis
Etihad Airways is starting a new three-class evening flight between Abu Dhabi-Mumbai, marking its inaugural first class service to India.
The 292-seat Airbus A340-600 aircraft will seat 12 passengers in Diamond First Class, 32 in Pearl Business Class and 248 in Coral Economy.
New mid-afternoon services to Mumbai and New Delhi on Airbus A320s, each seating 136 passengers, have also been introduced as the Abu Dhabi carrier ups capacity amid strengthening demand.
The Abu Dhabi-Delhi evening service has also been upgraded to a 254-seat Airbus A330-200 aircraft, with 18 business class and 236 economy class seats. The expanded schedules come into immediate effect.
The new Etihad flights will also be marketed by Jet Airways as an extension of the airlines' existing codeshare partnership.
President and chief executive officer of Etihad Airways, James Hogan, said these increases enable the airline to not only serve local traffic demands but also deliver much greater international connectivity for business and leisure travellers.
"Travellers from India will have more opportunities to connect with flights to destinations including Abu Dhabi, the GCC, Middle East, Africa, Europe and North America, while those flying to India will benefit from additional seats and more schedule options, providing greater travel flexibility," he said.

Dextromethorphan, a chemical commonly found in cough and cold medications, has been making its rounds as a party drug among teens and college students due to its accessibility and hallucinogenic properties, according to various websites.
Usually called DXM, Triple C's, or Robo, dextromethorphan is a derivative of morphine that when taken in high doses can cause hallucinations, dissociation, and loss of simple motor skills. The medication's extreme effects have been compared to those of the illegal drugs PCP (Phencyclidine) and Ecstasy, but it is the active ingredient in Mucinex DM, Robitussin and Nyquil which is found openly on the shelves at most stores including convenience stores and the Seminole State Sanford/Lake Mary campus bookstore.
Workers in the bookstore expect customers to be responsible adults and use the provided medications by the recommended dosage labeled on the back of the package.
Florida is one of the few states with laws in place that require buyers to show an ID when purchasing anything containing the drug. Most states don't require an ID, making it easier for underage individuals to purchase it, though in many cases users claim to just steal it. Some people also prefer ordering it online on every day sale sites such as Amazon, which is a lot harder to restrict.
Different doses of the drug result in what is referred to as various "plateaus," meaning that the more an individual takes the more their experience will vary. Sites such as Erowid.org have detailed the different plateaus and dosages recommended to reach them, enabling newer users to knowledgeably dose themselves.
Many people claim this site enables underage people to partake in the recreational use of the drug, despite the site not being an easy find unless one intentionally seeks it out, but this judgment is left to the individual.
Dextromethorphan's psychological effects normally include dissociation; a feeling of disconnect from one's self, paranoia, immense feelings of joy or love, hallucinations, and mental slowness. Motor skills can also be inhibited, making it difficult to walk, talk and properly control their extremities.
Overheating, sweating, extensive urination, nausea and blotchy red skin are also known effects of overdosing on the medication. Many users report an intense feelings of exhaustion and zoning out during the "come down" period when the effects begin to stop. In 2004, the Drug Abuse Warning Network reported that just under 1 percent of drug-related emergency room visits were due to DXM related medications.
With each use, the user is required to up the dose if the chemical hasn't been given time to completely make its way out of their system, the search for the same high as the first is what causes a lot of users to dose themselves up to a 1000 milligrams at once, increasing the risk of long-term effects such as liver failure, insomnia, extended amounts of dissociation, withdraw fatigue and even overdose.
The recreational use risk of this drug, while still debated among users on online chatrooms and forums, varies depending on the user and the dosage. The availability and affordability may make it seem like the perfect drug investment to some, but individuals must take their own physicality into account and decide what is best for themselves when faced with a decision regarding any kind of drug.
It's important for individuals to stay informed about what they're getting themselves into and to take any and all precautions they can to keep themselves healthy and alive. If you feel like you need help or someone to talk to, contact a campus counselor at 407-708-2337 during campus hours or 407-416-9976 Monday to Thursday after 6 p.m. and 24 hours on the weekends.


It's hard not to notice the grid lines present on the canvases, which hint at their photographic origins. Greenfield-Sanders uses photography as both a technique and a subject. Known for her meticulous process, her paintings are based on found vintage photographs from the 1950s and '60s that she digitally manipulates and transfers through different media (including watercolor and pencil) before arriving at the final paintings.

It's that time of year again, when people in small towns all over this country lock their cars and their back doors to forestall neighborly gifts of summer squash. Here in the big city, we always lock our doors, and we have to pay real money for our zucchini, but we are probably still getting a bit tired of the elongated green gourd, and looking for something useful to do with it that doesn't involve either frying it or dumping slices in the steamer basket. And as a college friend of mine once said, "Anything can be good and useful if it's made of chocolate!" So, therefore, it's time for chocolate zucchini cake. This recipe comes from King Arthur Flour's Whole Grain Baking (Countryman Press, 2006; p. 426), and it's the last of the King Arthur whole-grain recipes on my agenda until December. (I changed my mind about banana crunch cake and peanut butter cream pie, previously scheduled for September.) This cake has an unusual assembly method, as is often the case for cakes that incorporate fruits or vegetables, so let's see how it came together.
We start, of course, with the mise en place. The recipe calls for all traditional whole-wheat flour; I had a few ounces of whole spelt flour, and a fresh bag of sprouted whole wheat flour, both of which can be substituted for regular whole wheat (the total quantity is 10 oz or 280 g). The leavening, which I added directly to the flour, is a teaspoon of baking powder, with a teaspoon of soda added to react with a half-cup of nonfat buttermilk that's part of the wet works. Other dry ingredients include a half-teaspoon of salt, 6 ounces (170 g) of semisweet chocolate chips, and 1½ oz (45 g) of natural (not Dutch-process) cocoa powder. The wet team, in addition to the buttermilk, includes three eggs, 7½ oz (210 g) of light brown sugar, 3½ oz (100 g) of white sugar, and — most unusually — 4 ounces (115 g) of either butter or vegetable oil. If either butter or oil was acceptable, I figured melted butter must be acceptable as well, so I melted a stick of butter in the microwave, using the Pyrex bowl I intended to mix everything in anyway. Finally, there's the zucchini. The recipe calls for a pound of shredded zucchini, but it also gives a volumetric measurement, two cups, and I found that two cups of firmly packed shredded zucchini, as measured using my Adjust-a-Cup measure, was actually more like 12 ounces (340 g) than a pound (450 g) — which was good, because it meant that I didn't have to shred a fractional zucchini.
Unlike many of the cakes I've done this summer, this one is not made by the creaming method — that would be impossible to do, if one were using the vegetable oil option, although I could have done it if I hadn't melted the butter. Doing it this way allowed me to keep the flavor of the butter without having to wait for it to soften sufficiently to cream with the sugar — the result is obviously very different looking. Melting the butter liberates the water contained within, which dissolves a small fraction of the sugar, but mostly this still looks like a big lump of brown sugar.
After mixing in the eggs, vanilla, and buttermilk, the batter is quite loose and looks a bit curdled — probably because the eggs and buttermilk were still a little cold, so some of the butterfat resolidified rather than being emulsified with the eggs.
The dry ingredients are whisked together and added in two lifts, with the shredded zucchini in between, giving what is still a fairly wet, barely pourable batter. Chocolate chips are stirred in along with the second half of the dry ingredients. I chose to bake this cake in a 10-inch (250 mm) tube pan, previously lubricated with baking spray. It's cooked for about 45 minutes in a 350°F (175°C) oven, until a tester inserted in the center comes out moist but clean.
After cooling the cake in its pan for about 15 minutes, I turned it out onto the rack to finish cooling. A few of the chocolate chips stuck to the bottom of the tube pan, leaving voids in the top of the cake, but that will be fixed by covering the cake in a simple chocolate glaze — a ganache, in fact, made from 4½ oz (130 g) of chocolate chips, a half-cup (120 ml) of heavy cream, and a couple teaspoons of corn syrup (honey or glucose syrup would do as well).
When I brought it in to work, I was the only person who could taste the zucchini. Most people quite liked it, and one taster raved. The zucchini did what it was supposed to do, imparting moistness and a soft texture to the cake without interfering with the chocolate flavor.
Unlike most tube cake recipes, this one is specified to make 16 servings (as opposed to 20). If you leave off the glaze, the servings are about 90 g each and 50 kcal cheaper.

Q: Maven creating incorrect manifest file, jar file isn't executable, because main class isn't specified I'm trying to produce a .jar file that I can execute through command prompt. I am using Maven with this project so that I can use Unirest (to get data through a realtor API). First, however, I am trying to compile a simple "hello world" program to an executable .jar file, and Maven isn't adding the main-class attribute to the Manifest file. I used the instructions on this website under the "Maven Assembly Plugin" section. Here's the relevant portion of the pom.xml:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-assembly-plugin</artifactId>
<executions>
  <execution>
    <phase>package</phase>
      <goals>

         <descriptorRef>jar-with-dependencies</descriptorRef>
       </descriptorRefs>
     </configuration>
   </execution>
 </executions>
</plugin>

The .java file is located at java-realtor\src\main\java\com\javaRealtor\app\App.java. Do I need to specify the MainClass part of the plugin differently? I tried using just com.javaRealtor.App as well, but that didn't work. The manifest file (I extracted the jar to view it so I could maybe figure out what was going on) still doesn't have a line for a main class.

A: You need to use shade plugin for this transformation
<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-shade-plugin</artifactId>
  <version>3.2.4</version>
  <executions>

      <configuration>
        <transformers>
          <transformer

Q: Is html5 iframe preferable in Lightning component We have a requirement to fire an api and show the response using Lightning components. XSLT transformation has to be done on the response to get the actual content.
As it is not possible to use XSLT with salesforce, we have used html5 iframe in the lightning component.
Is iframe preferable in lightning component ? Plase suggest any alternatives if iframe is not preferable.

A: The use of an iframe is the recommended approach:

In those situations, we recommend that you put code that needs access to external resources in a "worker iframe" using Visualforce. The technique looks something like this.

<aura:component ...>
    <aura:attribute name="message" type="String"/>
    <aura:attribute name="vfHost" type="String"/>
    <!-- Input field for message "data" -->
    <lightning:input type="text" label="Message:"
        value="{!v.message}"/>
    <lightning:button label="Send to Visualforce"
        onclick="{!c.sendToVF}"/>
    <!-- The Visualforce page to send data to -->
    <iframe aura:id="vfFrame"
     src="{!'https://' + v.vfHost + '/apex/myvfpage'}"/>
</aura:component>

XSLT can also be done via MuleSoft, but that may be overkill.

This year, the Summerland Alliance Gardens had 40 serviced garden plots, with most being used. (John Arendt - Summerland Review)
Summerland Alliance Gardens to hold squash harvest
Organizers see increased interest in gardening during COVID-19 pandemic
Sep. 10, 2020 1:35 p.m.
Organizers of a community garden project in Summerland are preparing to harvest their squash later this month.
The Summerland Alliance Gardens, at the Alliance Church property on Victoria Road North, included an area dedicated to growing squash this year.
Christina Ripley, one of the organizers of the garden project, said the squash will be ready for harvest near the end of September.

READ ALSO: QUIZ: Exploring gardens
Some of the squash will be delivered to the Summerland Food Bank and Resource Centre and some will be available to those who want it.
The gardens had 40 serviced plots available this year, and most were gardened by members of the community.
"This year, with COVID-19, there was much more of an interest in gardening," Ripley said.
This is the second year the gardens have been in operation.
For next year, organizers are hoping to have more garden plots available.
The squash harvest will be held Sept. 26 from 9:30 to 11:30 a.m.
Those who wish to attend are asked to contact Christina Ripley at 250-279-0071 or Kate Hobbs at 778-931-0292, or to email summerlandcommunitygardens@gmail.com.

Call volume shuts down FBI's firearm background checks, stops Maine sales on Black Friday
by Nok-Noi Ricker November 23, 2012 Updated November 24, 2017
BREWER, Maine — Sometime early on Black Friday, the FBI's National Instant Criminal Background Check System, or NICS, went down and stopped all gun sales, Bangor-area gun dealers said.
High call volumes caused "intermittent outages" in the system, an FBI spokesman confirmed Friday afternoon.
"It means we can't sell no damn guns," Rick Lozier, a manager at Van Raymond Outfitters in Brewer, said at about 1:15 p.m.
"NICS is down, which means nobody is selling guns right now, on Black Friday," said Ralph McLeod, owner of Buyers Guns in Holden.
Those who want to purchase a gun in the U.S. must fill out and sign FBI paperwork. The gun dealer then calls NICS to see if the buyer is barred by federal law from possessing firearms.
"The message is they are going to be down for a few hours," McLeod said at about noon Friday.
Black Friday sales played a role in the problems with NICS, the director of the FBI's Criminal Justice Information Services Division said, responding to an email from the Bangor Daily News.
"The NICS has experienced intermittent outages today due to high call volumes," Stephen G. Fischer Jr. said at about 2:15 p.m.
Lozier, who has worked at Van Raymond's for more than a decade, said the outages cost him at least half a dozen customers by the time the business day was only half over.
"If we can't call it in, we can't sell a gun," Lozier said. "It's cost us some money."
The NICS is a name-check system that combs available records in the National Crime Information Center, the Interstate Identification Index and the NICS Index to determine if prospective firearm purchasers are disqualified from receiving or possessing firearms, the FBI's website states.
Most potential buyers who went away empty-handed from Buyers and Van Raymond on Friday can return, but such a problem can be a major inconvenience for shoppers from Aroostook County and other rural areas of Maine.
"If it's somebody from Houlton, they can't come back tomorrow," Lozier said.
"The saving grace for me is I do a lot of online sales and online sales are not instant," McLeod said.
A man who answered the phone at Dick's Sporting Goods in Bangor said he thought the federal background check system may be overloaded because Friday was a big shopping day.
McLeod and Lozier said the FBI should consider installing an auxiliary system to handle calls when NICS fails to work.
"You would figure they would have a backup system," McLeod said.
Another frustrating part of the FBI's background check system, he added, is that gun dealers don't know NICS is down until they try to call in.
"It's happens every now and then," Lozier said of the system being down. "And it doesn't matter when it does — it's an inconvenience."

27,000-Year-Old Tooth of Giant Ground Sloth Sheds Light on Animal's Diet and Climatic Exposure
By analyzing a tooth from the first fossil remains of the extinct Pan-American sloth (Eremotherium laurillardi) found in Belize, a team of paleontologists has uncovered insights into the creature's dietary adaptations, as informed by local climate.
The Pan-American sloth had a distribution from southern Brazil to the Gulf and Atlantic coast regions of North America.
This animal could reach a length of 20 feet (6 m), which, in an upright position, would have permitted it to feed at higher levels in trees.
In 2014, divers found the fossil remains of a 27,000-year-old Pan-American sloth — parts of a tooth, humerus and femur — while searching for ancient Maya artifacts in a water-filled sinkhole in Cara Blanca, Belize.
Though partially fossilized, the tooth still held enough unaltered tissue for stable carbon and oxygen isotope analysis, which provided clues to what the sloth ate in the last year of its life. This, in turn, revealed much about the local climate and environment of the region at the time.
"Our findings add to the evidence that many factors, in addition to a changing climate, contributed to the extinction of megafauna in the Americas," said co-lead author Professor Lisa Lucero, from the Department of Anthropology at the University of Illinois at Urbana-Champaign.
"One of those potential factors is the arrival of humans on the scene 12,000 to 13,000 years ago."
"The teeth of giant sloths like the one found in Belize, Eremotherium laurillardi, differ from those of other large mammals, like mammoths, that went extinct between 14,000 and 10,000 years ago," said first author Jean Larmon, a graduate student at the University of Illinois at Urbana-Champaign.
"Giant sloth teeth have no enamel, the hard, outer layer of human and some animal teeth that can be analyzed to learn about their diet."
By using cathodoluminescence microscopy, a technique that causes minerals to glow and can detect the extent of mineralization in fossils, the researchers discovered that one type of tooth tissue, the dense orthodentin, was largely intact.
They drilled 20 samples of orthodentin for isotopic analysis along the 3.9-inch (10 cm) long tooth fragment, spanning more than a year of tooth growth.
"This allowed us to trace monthly and seasonal changes in the sloth's diet and climate for the first time, and also to select the best part of the tooth for reliable radiocarbon dating," said Professor Stanley Ambrose, also from the Department of Anthropology at the University of Illinois at Urbana-Champaign.
The isotopic analysis revealed that the giant sloth lived through a long dry season, which lasted about seven months, sandwiched between two short rainy seasons.
It also revealed that the creature lived in a savanna, rather than a forest, and consumed a variety of plants that differed between wet and dry seasons.
"We were able to see that this huge, social creature was able to adapt rather readily to the dry climate, shifting its subsistence to relying upon what was more available or palatable," Larmon said.
"This supports the idea that the sloths had a diverse diet. That helps explain why they were so widespread and why they lasted so long. It's likely because they were highly adaptable," Professor Lucero said.
The findings were published in the journal Science Advances.
