Abstract: FIELD: medicine. 
     SUBSTANCE: invention refers to medicine, namely to pulmonology, and concerns a method for predicting the progression of chronic obstructive pulmonary disease (COPD). Essence of the request consists in the following: a patient's venous blood is examined for a relative number of granulocytes expressing Toll-like receptor 2 (CD282 +  granulocytes); the relative number of granulocytes expressing the interleukin-6 receptor (CD126 +  granulocytes); relative amount of T-regulatory cells (CD4 + CD25 + CD127 - ). A risk factor Kp = (CD126 +  granulocytes + CD282 +  granulocytes) / CD4 + CD25 + CD127 -  is calculated. If Cr is equal to or greater than 33 standard units, unfavorable course of COPD with high risk of disease progression is predicted. If Kp is less than 33 standard units, favorable course of COPD with low risk of disease progression is predicted. 
     EFFECT: invention enables detecting and preventing progression of COPD at early stages of the disease.

Abstract: Die Erfindung betrifft eine Vorrichtung zur Zubereitung von Flüssigfutter für die Viehmast, mit einem auf Wiegezellen stehenden Silo- oder Mischbehälter, in den die einzelnen Futterkomponenten in Abhängigkeit der von den Wiegezellen gemeldeten Menge sind. Vorrichtungen dieser Art werden lediglich zu vorbestimmten Zeiten in Betrieb gesetzt, nämlich meistens unmittelbar vor den Fütterungszeiten. Dadurch sind unwirtschaftliche Leerlaufzeiten gegeben. Durch die Anordnung weiterer Plattformen od.dgl. neben den Behältern auf den Wiegeelementen, kann die Vorrichtung auch für andere Zwecke als alleine für die Fütterungszubereitung bzw. Fütterung genutzt werden, z.B. zum Wiegen von Vieh, geernteten Rüben, Kartoffeln usw. Diese Maßnahme hat den Vorteil, daß sich die eigentlichen Betriebszeiten der Vorrichtung verlängern und demzufolge ihr Einsatz in einem landwirtschaftlichen Betrieb wirtschaftlicher wird.
