В 2018 году ученые из Университета Колорадо в Боулдере (США) закрепили на двух ясенях в университетском парке акселерометры, чтобы измерять характер их раскачивания. Сегодня, спустя четыре года наблюдений, у них набралось достаточно данных для разработки новой безопасной технологии отслеживания роста деревьев. Она практически идеальна для городских условий и позволяет контролировать каждое дерево в отдельности.
Дерево, будучи живым организмом, непрерывно меняет свою структуру и поведение, и во многом это зависит от концентрации воды в его тканях. Как выяснили американские ученые, весной в период распускания почек в деревьях особенно много влаги, поэтому с одной стороны они становятся более тяжелыми, а с другой — более гибкими. Это напрямую влияет на характер их раскачивания на ветру, что незаметно человеческому глазу, но может быть зафиксировано акселерометрами.
Измерения на ясенях доказали правоту ученых – зимой сухая и легкая древесина раскачивается мало, а по весне наоборот. Более того, по характеру раскачиваний можно с высокой точностью определить периоды роста растения и даже рассчитать, сколько оно прибавит в массе и размерах. И при этом не требуется брать образцы на анализ, не нужно повреждать дерево – данный метод может стать революционным в области озеленения общественных пространств.

In reproductive goal tissues, testosterone can be thought-about to be a prohormone,

as hydrophilic statins are regarded as more hepatoselective
(153). If the statin just isn’t tolerated, it is advisable to vary to a lipophilic
statin (e.g. simvastatin or atorvastatin), scale back the dose, or attempt an alternate-day routine (154).
If regardless of these attempts statin intolerance remains a problem, other pharmacological choices,
such as ezetimibe or proprotein convertase subtilisin/kexin kind 9 (PCSK9) inhibitors, ought to
be explored. The stimulatory impact on erythropoiesis is dose-dependent – at least beyond 300 mg testosterone enanthate weekly – and
is extra pronounced in older men (42). It takes a number of months
