Abstract: Embodiments of the disclosure concern the use of expression constructs in which at least one polyA signal is embedded upstream of an expressible transcript, such as within a 5? UTR for the transcript, for example. In certain embodiments, the polyA signal is comprised within a ligand-binding aptamer, and the binding of the ligand to the aptamer, or lack thereof, dictates the outcome for the expressible transcript. In specific embodiments, absence of the ligand causes the expressed transcript having a polyA in its 5? UTR to be expressed but then degraded, whereas presence of the ligand causes inhibition of degradation upon expression of the expressible transcript. More than one ligand-binding aptamer may be present on the same expression construct.

Abstract: Provided are a method for preparing an adsorbent from industrial vermiculite, an adsorbent and application thereof. The method comprises steps: flaking and de-polluting the raw industrial vermiculite ore to obtain industrial vermiculite fine flakes; grinding the industrial vermiculite fine flakes to obtain industrial vermiculite powder; mixing the industrial vermiculite powder with a binder and granulating it to obtain an industrial vermiculite granular; and post-treating the industrial vermiculite granular to obtain the adsorbent. The adsorbent is prepared by the method. Applications may include purification of benzene gases such as toluene, sewage treatment, horticulture, soil improvement and applications in agricultural carriers. The adsorbent of the disclosure has the advantages of high cation exchange capacity, large internal specific surface area, strong adsorption of toluene and lightweight porous, etc.

Abstract: Disclosed are a method, device, and system for monitoring a photovoltaic power station. The device for monitoring the photovoltaic power station may display prompt information with respect to a first photovoltaic device on a display of the device in response to determining, based on the operation data of the first photovoltaic device, that the first photovoltaic device operates abnormally. Thus, a monitoring engineer may judge whether the first photovoltaic device is faulty in time based on the prompt information, facilitating the guide of subsequent operation and maintenance according to the operation data of the photovoltaic device, which not only is higher in flexibility but also ensures the efficiency of fault detection.
