Gulf of Mexico low-frequency ocean soundscape impacted by airguns.
The ocean soundscape of the Gulf of Mexico (GOM) has not been well-studied, although it is an important habitat for marine mammals, including sperm and beaked whales, many dolphin species, and a potentially endangered baleen whale species. The GOM is also home to high levels of hydrocarbon exploration and extraction, heavily used commercial shipping ports, and significant fishery industry activ...
متن کاملAsthma is a Serious Danger
میزان مرگ و میر آسم طی دهه گذشته بطور چشمگیری تغییر کرده است. با مبتلا کردن ۱۵ میلیون آمریکایی میزان مرگ و میر در سال ۱۹۷۸، به رقم ۱۸۷۲ نفر و ۹ سال بعد، به بیش از ۴۰۰۰ نفر رسید. علت چنین افزایش چشمگیری روشن نیست. علل احتمالی عبارتند از کاهش ظرفیت تنفس، استفاده بیش از حد از داروهای استثنائی و استنباط غلط بیماران و نیز مراکز درمانی نسبت به شدت بیماری است. بررسی دقیق، معالجات مناسب و آموزش به ب...
متن کاملThe danger of chaperones.
The growing pressure on GPs to use chaperones when conducting intimate examinations (vaginal, rectal, breast, testicular) reveals an alarming deterioration in doctor–patient relationships. The peculiar intimacy of the relationship between doctor and patient renders the patient vulnerable to the doctor's abuse of power. Hence, making a sharp distinction between doctor and lover has been one of t...
متن کاملSensing danger.
CRISPR-Cas loci encode for an adaptive immune system in prokaryotes that provides defense against viruses (1) and plasmids (2) that infect these organisms. CRISPR loci contain a series of repetitive sequences intercalated with short sequences derived from invading viruses and plasmids (3–5). These short sequences, called spacers, are acquired from the invader upon infection during an “immunizat...
متن کاملDanger Invariants
Static analysers search for overapproximating proofs of safety commonly known as safety invariants. Fundamentally, such analysers summarise traces into sets of states, thus trading the ability to distinguish traces for computational tractability. Conversely, static bug finders (e.g. Bounded Model Checking) give evidence for the failure of an assertion in the form of a counterexample, which can ...
