What Is the World’s Fastest Speedboat?

An air medical communications specialist at the University of Pennsylvania Health System, Nathan Rotenberg brings a wealth of experience and expertise to his role, drawing on a background that extends beyond Pennsylvania to include Southern New England (Connecticut, Massachusetts and Rhode Island). He coordinates transport requests and facilitates communication between transport teams and medical centers. During his free time, Nathan Rotenberg enjoys flying and boating.

As of March 2023, the world’s fastest boat in history is the Spirit of Australia, a handmade wooden speed boat that draws its power from a Westinghouse J34 jet engine. This engine is also used in combat jets and planes. The boat attained the groundbreaking speed record of 317.6 mph at Blowering Dam in 1978. Before 1978, the Bluebird K7 used to be the fastest speedboat in history, with a monumental record of 276 mph in 1964.

Australian racer Ken Warby handcrafted and piloted the Spirit of Australia, making him the first man to design, build, and pilot a speed record hydroplane in history. He died in February 2023.

The Types and Symptoms of Soft Tissue Sarcoma

Nathan Rotenberg is a coordinator for various critical care transport services. Additionally, Rotenberg is well vested in the fight against cancer. Growing up in Connecticut, he is a significant gift co-founder and principal of the Sandra Lee and Barry Rotenberg Endowment Fund for Adult Sarcoma Research at Dana-Farber | Harvard in Boston, MA.

One type of the disease is soft tissue sarcoma (STS), a malignant tumor originating in soft tissue that includes cartilage, muscle, fat, and deep skin layers. Adult fibrosarcoma is among the types of STS that develop in areas of the body such as the arms, trunk, and legs. Rare and aggressive, this form of STS starts in connective tissues such as the tendons and fascia and is difficult to treat. Another type, called Evans tumor, a low-grade fibromyxoid sarcoma is a slow-growing, painless tumor that is simpler to treat.

There are several other types of STS, and they share a common symptom of a swelled area or a lump. The areas may be painless if the tumor does not press against muscles or nerves. With or without associated pain, lumps turn out to be noncancerous fat cell tumors, known as lipomas, that are not STS.

In the past, the discovery of sarcoma in a limb might necessitate the removal of that limb. Today, surgical approaches focus on the targeted removal of compromised tissue, followed by a tissue graft or implant. In addition, radiation therapy may help ensure the tumor does not return in conjunction with targeted therapies such as chemotherapy.

The Flexible Use of “a” as a Preposition in Spanish

Critical care transport coordinator Nathan Rotenberg has a position with the University of Pennsylvania Health System and a background that extends to Connecticut. An avid traveler, Nathan Rotenberg has studied Spanish and is increasingly becoming fluent in the language.

One of the most common prepositions in Spanish is “a,” which often means the equivalent of the English “to.” For example, “cayo al piso” means “it fell to the floor.” The English preposition can be different, though with a similar directional quality: “Llegamos a Chile” means “we arrived in Chile.”

Unlike “to,” however, the Spanish “a” has many additional uses, including a connector between verbs and infinitives. For example, “comenzo a bailar” means “he starts dancing,” This usage is particularly common for expressing future intentions or likely outcomes. Often, the “a” would not appear as a preposition in the English translation.

Another use of “a” indicates the method or manner of a certain action. For example, “andan a ciegas means “they are walking blindly.” Because there is a multitude of related and unusual uses, such as “encontre a Fido,” “I found Daisy,” the best way to learn the full range is through memorizing examples.

Canine Search Teams for Human Remains Detection

A graduate of the International Academies of Emergency Dispatch, Nathan Rotenberg holds an A-EMD, and currently serves as the air medical communication specialist at Penn Medicine. A graduate of the Pennsylvania Seach & Rescue Council (PSARC), Nathan Rotenberg is specialized in search and rescue and human remains detection.

In the event of a disaster, canine search teams and search parties start looking for survivors and human remains. Canine search teams are used to search and find human remains in any environment and are not distracted or limited by sounds. These search teams are used after an initial search was made by authorities. They can pick up human scent even from miles away and even if the survivors are buried well underground. The canines are trained to know the difference between many types of scents such as animal remains, human remains, and other distracting odors.

Canines that enter search teams all have a trained handler and must be at least 18 months old. They must earn certification, which is obtained by passing tests for agility skills, and command response. Canines must also be persistent enough to search by themselves for long periods of time and under any circumstance, even if that means passing through dark tunnels or facing extreme temperatures.
