Разработка и исследование конструкции привода управляемого задерживающего устройства шароструйно-эжекторного бурового снаряда

В работе рассмотрены принципы шароструйного бурения, а так же устройство шаростуйно-эжекторного снаряда. Предложены варианты модернизации данного снаряда.In this paper, the principles of pellet impact drilling, as well as the construction of a pellet-ejector projectile, are considered. Variants of modernization of this projectile are offered

Clinical, anthropometric, metabolic variables and nocturnal respiratory registration data in PM and M obese women according to the presence of OSA.

<p>FH: family history; BMI: body mass index; BP: blood pressure; IFG: impaired fasting glucose; IGT: impaired glucose tolerance; ISI: insulin sensitivity index; ΔI₃₀/ΔG_30: insulinogenic index; CRP: C- reactive protein; ESS: Epworth Sleepiness Scale; AHI: Apnea-Hypopnea Index; ODI: Oxygen Desaturation Index; SaO₂: nocturnal oxygen saturation. Data are expressed as mean ± SD except for CRP which is expressed as median (interquartile range).</p>a<p>p<0.05,</p>b<p>p<0.01,</p>c<p>p<0.0001 OSA vs no OSA women;</p>§<p>p<0.05,</p>§§<p>p<0.001 no OSA premenopausal vs no OSA menopausal women;</p>#<p>p<0.01 premenopausal OSA vs menopausal OSA women.</p

Kaplan-Meier curves of survival for patients with pulmonary arterial hypertension and patients with pulmonary hypertension due to left heart disease.

<p><b>In the panel a) patients with pulmonary hypertension due to left heart disease are all pooled together, while in the panel b) they are subdivided in three groups according to the diastolic pressure gradient and pulmonary vascular resistance.</b> CpcPH = combined post- and pre-capillary pulmonary hypertension; Interm = intermediate PH-LHD; IpcPH = isolated post-capillary pulmonary hypertension; PAH = pulmonary arterial hypertension; PH-LHD = pulmonary hypertension due to left heart disease.</p

Effects of varying the diastolic pressure gradient and pulmonary artery wedge pressure on the compliance-resistance relationship in patients with pulmonary hypertension.

<p><b>Panel a): pulmonary arterial compliance as a function of pulmonary vascular resistance, both logarithmically transformed. Panel b): resistance-compliance product as a function of pulmonary artery wedge pressure.</b> Ca = pulmonary arterial compliance; DPG = diastolic pressure gradient; PAH = pulmonary arterial hypertension; PH-LHD = pulmonary hypertension due to left heart disease; PVR = pulmonary vascular resistance; RC-time = pulmonary vascular resistance-compliance product.</p
