: Opis.: Cutaneous symptoms of a diseased pancreas: 20200413AD The pancreas produces hormones and pancreatic juice - substances we can't live without. Unfortunately, he doesn't warn us when he's in trouble. Find out what skin changes can indicate pancreatic disease. Purpura as a symptom of pancreatitis: Necrosis and subcutaneous tissue inflammation may indicate pancreatic cancer: Migratory erythema and pancreas: Itchy skin and sick pancreas: Jaundice is a symptom of pancreatic cancer: Purpura is a symptom of pancreatitis: Along with fever, nausea, vomiting, stomach ache and an increase in the level of the pancreatic enzyme - amylase - one of the symptoms indicating acute pancreatitis (ACS). The disease most often occurs as a result of alcohol abuse or due to cholelithiasis. The prognosis for acute pancreatitis depends on many factors, such as age, clinical features, comorbidities and imaging results. Skin lesions in the form of a mottled rash appear mainly on the lateral surfaces of the trunk and in the navel area, and are the result of the accumulation of hemorrhagic peritoneal fluid in the subcutaneous tissue. In the course of the disease, mottled cyanosis (Walzel's symptom) may also appear in the area of the abdominal wall and trunk. Read more: Acute and chronic pancreatitis - symptoms, treatment Necrosis and inflammation of the subcutaneous tissue may indicate pancreatic cancer Subcutaneous tissue necrosis in the course of pancreatitis most often affects patients between 30 and 40 years of age. Clinically, the eruptions are in the form of tumors or papules with a diameter of about 1-5 cm. They occur primarily on the arms, torso, buttocks, thighs and lower legs. In severe cases, painful bumps spontaneously rupture and leave depressed, discolored scars. Patients with numerous inflammatory and necrotic eruptions often have a fever, and also complain of abdominal pain and vomiting. Histopathological examination determines the diagnosis of inflammation and necrosis of the subcutaneous tissue. Subcutaneous tissue necrosis may coexist with pancreatic cancer. Migraine and pancreas Many benign and malignant pancreatic tumors have the ability to produce and release various hormones that can provoke skin lesions. An example is the so-called migratory erythema that occurs in the case of a glucagonoma tumor (a glucagon-producing pancreatic cancer). Initially, the lesions have the nature of erythema of varying diameter, and a bladder appears in the central part. After breaking the cover, a necrosis foci is formed, covered with a dark necrotic scab, which heals, leaving a discoloration. Active changes are accompanied by pain and itching. Skin changes will appear primarily on the limbs, then around the mouth, in the uplifted areas, especially in the perineum and lower abdomen. Efflorescence can mimic eczema, contact dermatitis, thrush, psoriasis or purulent staphylococcal dermatitis. In addition to migratory necrotizing erythema, patients often have symptoms of stomatitis and tongue inflammation. Itchy skin and sick pancreas: This is a symptom resulting from the appearance of protein complexes with bilirubin just under the skin - such a specific introduction to jaundice. In most patients, however, it does not show up as a change in skin color due to low bile pigmentation. Itching can be of various severity, chronic, lasting more than six weeks, may be the first signal of an ongoing tumor process. Jaundice is a symptom of pancreatic cancer: Jaundice is the yellow coloration of the skin, mucous membranes and the whites of the eyes, caused by excessive bilirubin in the blood serum. Sometimes it may be accompanied by discoloration of the stool and darkening of the urine, as well as itching of the skin. Jaundice is a symptom that occurs in almost 90 percent. patients with pancreatic cancer. It can be caused by compression of the bile ducts by a tumor (primarily the head of the pancreas or Vater's warts) or by enlarged lymph nodes and obstructions in the flow of bile from the liver to the intestine, as well as damage to the liver by cancer metastases. Both causes can coexist.

: Opis.: The Diesel Riddle: The Diesel Engine: A Drive for More Justice: The diesel riddle gives an insight into the dramatic invention of the diesel engine at the end of the 19th century and brings Rudolf Diesel's moving fate to life. Today his invention is the backbone of the global economy: The diesel engine that Rudolf Diesel developed at the end of the 19th century not only drives trucks, cars, tractors or ocean-going ships, but also power plants that produce electricity and heat all over the world . But the success of his invention ultimately brought the idealistic inventor himself no luck. He often works beyond his limits and risks his health: The young engineer Rudolf Diesel made it his life's work at the end of the 19th century to develop a new type of engine. The steam engine has proven itself at the time. But it consumes tons of expensive coal. That is why only wealthy steam engines can pay. It simply takes the work away from the artisans and drives them into poverty. One machine for everyone The young engineer Rudolf Diesel wants to change the situation. He wants to build a new type of engine that many can afford. His idea is to build an engine that is small and handy. In addition, with unprecedented performance and with a significantly lower consumption of expensive fuel. Other inventors have tried to replace the steam engine with gas and gasoline engines. However, such motors can only be used to a limited extent and cost enormous sums. Diesel expert Viktor Glass tells an anecdote about Diesel's "black mistress" - what diesel engines were called at that time. Rudolf Diesel's engine was supposed to work on a new principle: auto-ignition. Air is heated to several hundred degrees simply by compressing it. If fuel is then injected, it ignites on its own. Diesel came up with the idea through a common compression lighter. Air is compressed so quickly and firmly in a glass flask with easily combustible scale that the scale glows due to the heat of the pressure. Diesel hopes to be able to ignite any fuel at a much higher pressure - and reduce fuel consumption. Enormous hurdles Many consider the young engineer to be a non-realistic dreamer. Nobody can imagine that a material can withstand the enormous pressure that Diesel's diesel engine needs. It is also unclear how the fuel should be injected. At that time, pumps and precise valves were not available for injecting the fuel into the combustion chamber in a metered manner. The process is still the key moment in the development of a diesel engine: the timing of the injection must be precisely calculated to the thousandth of a second, as must the amount of fuel that is only a few drops for the auto diesel. First operational model It is difficult for him to find an investor. It is only when Diesel wants to reduce the pressure in the engine to a fraction of its last calculation that it receives an approval from the Augsburg machine factory. After all, the Friedrich Krupp company also made a financial contribution, and Diesel was finally able to develop its test engine in 1893. But the planned half-year development period turns into four years with many setbacks: the first functional model was completed in 1897. It has an output of 20 hp. The triumphal march of the new engine began at the beginning of the 20th century. His concept is constantly being improved and adapted. Diesel tirelessly travels the world to sell licenses for its engine. The industrialists fight for the contracts, the inventor quickly becomes a millionaire. But years of patent processes not only destroy Diesel's health, it also goes downhill economically - as a businessman, the ingenious inventor has no talent. Mysterious disappearance Finally, through his invention, Rudolf Diesel becomes the focus of politics. The emperor is said to have read his book on the engine. But Diesel refuses requests from the Imperial Navy. He lets him know that he is not making his engine available for war purposes. This triggers displeasure. But the engineer is increasingly troubled by financial problems. Although the outbreak of the First World War heralds, Diesel is preparing a business meeting in the rival country Great Britain. On September 29, 1913, he boarded the Dresden steamer to later attend a meeting in London for the inauguration of a new factory for diesel engines. He appears to be in a good mood, but is never seen again after going to his cabin in the evening. Victim of a murder plot? On October 10, the crew of a Dutch pilot boat found the body of a man in the water. A few days later, Eugen Diesel identified his father's body. The exact circumstances of death are never clarified. His survivors question the theory that the inventor killed himself in the face of impending financial ruin - even if there are signs of suicide. In fact, there is a suspicion that the inventor fell victim to a plot to murder. One of the theses says that Diesel was murdered in the face of the approaching First World War. Because he sold licenses for his engine to the two rival powers France and England - which displeased the German military. Another thesis assumes that diesel was removed on behalf of the oil industry because he was currently working on a biodiesel variant. Because it was also his goal to become independent of oil. To date, the mystery surrounding Rudolf Diesel's myterious circumstances has not been solved.

: Opis.: Zagadka Diesla: Silnik Diesla: Napęd dla większej sprawiedliwości: Zagadka z silnikiem Diesla daje wgląd w dramatyczny wynalazek silnika Diesla pod koniec XIX wieku i ożywia losy Rudolfa Diesla. Jego wynalazek jest obecnie podstawą globalnej gospodarki: silnik Diesla, który Rudolf Diesel opracował pod koniec XIX wieku, napędza nie tylko ciężarówki, samochody, traktory lub statki oceaniczne, ale także elektrownie produkujące energię elektryczną i ciepło na całym świecie . Ale sukces jego wynalazku ostatecznie nie przyniósł samemu idealistycznemu wynalazcy szczęścia. Często pracuje poza swoimi granicami i ryzykuje zdrowie: młody inżynier Rudolf Diesel pod koniec XIX wieku opracował nowy typ silnika. W tym czasie sprawdził się silnik parowy. Ale zużywa mnóstwo drogiego węgla. Dlatego tylko zamożne silniki parowe mogą zapłacić. Po prostu odbiera rzemieślnikom pracę i wpędza ich w biedę. Jedna maszyna dla wszystkich Młody inżynier Rudolf Diesel chce zmienić sytuację. Chce zbudować nowy typ silnika, na który wielu może sobie pozwolić. Jego pomysłem jest zbudowanie małego i poręcznego silnika. Ponadto dzięki niespotykanej wydajności i przy znacznie niższym zużyciu drogiego paliwa. Inni wynalazcy próbowali zastąpić silnik parowy silnikami gazowymi i benzynowymi. Jednak takie silniki mogą być używane tylko w ograniczonym zakresie i kosztują ogromne kwoty. Ekspert od silników Diesla Viktor Glass opowiada anegdotę o „czarnej kochance” Diesla - jak wówczas nazywano silniki Diesla. Powietrze ogrzewa się do kilkuset stopni po prostu przez jego ściśnięcie. Następnie wtryskuje się paliwo, które sam się zapala, a Diesel wpadł na ten pomysł poprzez zwykłą zapalniczkę kompresyjną. Powietrze jest sprężane tak szybko i pewnie w szklanej kolbie z łatwopalną zgorzeliną, że skala jarzy się pod wpływem ciepła ciśnienia. Diesel ma nadzieję, że będzie w stanie zapalić każde paliwo przy znacznie wyższym ciśnieniu - i zmniejszyć zużycie paliwa. Ogromne przeszkody Wielu uważa młodego inżyniera za nierealistycznego marzyciela. Nikt nie może sobie wyobrazić, że materiał jest w stanie wytrzymać ogromne ciśnienie, jakiego potrzebuje silnik Diesla. Nie jest również jasne, w jaki sposób należy wtryskiwać paliwo. W tym czasie pompy i precyzyjne zawory nie były dostępne do wtryskiwania paliwa do komory spalania w odmierzany sposób. Proces ten jest nadal kluczowym momentem w rozwoju silnika wysokoprężnego: czas wtrysku musi być obliczony dokładnie z dokładnością do jednej tysięcznej sekundy, podobnie jak ilość paliwa, która jest tylko kilka kropli w przypadku silnika wysokoprężnego. Pierwszy model operacyjny Trudno mu znaleźć inwestora. Tylko wtedy, gdy Diesel chce obniżyć ciśnienie w silniku do ułamka swojej ostatniej kalkulacji, otrzymuje obietnicę od Maschinenfabrik Augsburg. W końcu firma Friedrich Krupp również wniosła wkład finansowy, a Diesel był w stanie opracować silnik testowy w 1893 roku. Ale planowany półroczny okres rozwoju zamienia się w cztery lata z wieloma niepowodzeniami: pierwszy model funkcjonalny został ukończony w 1897 roku. Ma moc 20 KM. Triumfalny marsz nowego silnika rozpoczął się na początku XX wieku. Jego koncepcja jest ciągle ulepszana i dostosowywana. Diesel niestrudzenie podróżuje po świecie, aby sprzedawać licencje na swój silnik. Przemysłowcy walczą o kontrakty, wynalazca szybko staje się milionerem. Ale lata procesów patentowych nie tylko niszczą zdrowie Diesla, ale także idą w dół z ekonomicznego punktu widzenia - jako biznesmen pomysłowy wynalazca nie ma talentu. Tajemnicze zniknięcie Wreszcie dzięki swojemu wynalazkowi Rudolf Diesel staje się przedmiotem polityki. Mówi się, że sam cesarz przeczytał swoją książkę na silniku. Ale Diesel odrzuca prośby z Imperial Navy. Daje mu znać, że nie udostępnia swojego silnika do celów wojennych. To powoduje niezadowolenie. Ale inżynierowi coraz bardziej przeszkadzają problemy finansowe. Chociaż wybuch pierwszej wojny światowej zwiastuje, Diesel przygotowuje spotkanie biznesowe w rywalizującym kraju - Wielkiej Brytanii. 29 września 1913 r. Wsiadł do parowca w Dreźnie, aby wziąć udział w spotkaniu w Londynie w sprawie inauguracji nowej fabryki silników Diesla. Wygląda na to, że jest w dobrym humorze, ale nigdy więcej go nie widzi po udaniu się do swojej kabiny wieczorem. Ofiara spisku morderstwa? 10 października załoga holenderskiej łodzi pilotowej znalazła ciało mężczyzny w wodzie. Kilka dni później Eugen Diesel zidentyfikował ciało ojca. Dokładne okoliczności śmierci nigdy nie są wyjaśnione. Jego ocaleni kwestionują teorię, że wynalazca zabił się w obliczu zbliżającej się ruiny finansowej - nawet jeśli istnieją oznaki samobójstwa. W rzeczywistości istnieje podejrzenie, że wynalazca padł ofiarą spisku morderstwa. Jedna z tez mówi, że Diesel został zamordowany w obliczu zbliżającej się pierwszej wojny światowej. Ponieważ sprzedał licencje na swój silnik dwóm rywalizującym mocarstwom - Francji i Anglii - co nie podobało się niemieckiej armii. Inna teza zakłada, że olej napędowy został usunięty w imieniu przemysłu naftowego, ponieważ obecnie pracował nad wariantem biodiesla. Ponieważ jego celem było także uniezależnienie się od ropy naftowej. Do tej pory tajemnica otaczająca tajemnicze okoliczności Rudolfa Diesla nie została rozwiązana.

: Opis.: A short story about ... Ancient Egypt: 3000 years of high culture on the Nile. No empire existed longer, none was so far ahead of its time. Monumental temples, the tombs in the Valley of the Kings and especially the pyramids of Giza bear witness to the achievements of the ancient Egyptians. What was the secret of this unique "success story"? What was the meaning of the cult of the dead? Mirko Drotschmann searches for traces in Egyptian museums, meets mummy researchers and is there when engineers at the University of Kassel decode an ingenious technique that was used to build the pyramids. Computer animations show what the pyramids of Giza looked like at the time of their construction and which secrets are still hidden inside today. Incest as a common marriage policy The history of the pharaonic kingdom begins with a treasure of nature: the Nile. The majestic stream crosses around 1000 kilometers of dry desert and gave Egypt fertility and wealth. Egyptian civilization developed on its banks. After the unification of Upper and Lower Egypt, the pharaohs ruled over the first centrally controlled state in history. Religious myths, the many gods and godlike pharaohs became the "glue" of society. The film shows how the rulers worshiped like gods, what their life in the palace looked like and why incest was part of the usual marriage policy. Magnificent tombs such as the pyramids of Giza or the underground tombs in the Valley of the Kings were built for the dead pharaohs. Deep chutes and mock doors should mislead grave robbers. But only the chamber of a rather unknown pharaoh remained undiscovered until the beginning of the 20th century: Tutankhamun's tomb. Hundreds of items such as precious jewelry, cult objects, amulets, weapons and everyday objects are still captivating to this day. Mirko Drotschmann travels to London, where, among other things, this legendary grave treasure will be exhibited until May 2020. The forefathers of our modern medicine were the Egyptians. The ancient travel writer Herodotus reported: Every place is full of doctors; there are doctors for the eyes, for the head, for the teeth, for the abdomen and for internal diseases. Egyptian doctors far ahead of their time The dead in ancient Egypt were saved from decay with incredible meticulousness. Some mummies still look like they died only a few years ago. For the researchers of the German Mummy Project, mummies are very special "organic archives" that provide information about the life and suffering of the ancient Egyptians: How did they eat? How old did they get? What did they die from? Have you tried to cure them? And what medications did they take or did they use drugs? The viewer learns that the Egyptian doctors were far ahead of their time. They operated on the head, amputated limbs and treated fractures. Successful - as studies on mummies prove. Tough power politics and the cult of the dead held the empire together for 3000 years. So-called foreign countries repeatedly tried to conquer rich Egypt, but it was not until 500 BC that the Persians, then Alexander the Great and finally the Roman Caesars succeeded in weakening the Pharaohs' land and finally bringing them to their knees. The intruders shaped the culture and the language. But have they also been immortalized in genetic terms? Researchers at the Max Planck Institute for Human History have for the first time succeeded in deciphering the genetic makeup of ancient Egyptian mummies. The results are amazing.
