The flexibility of metal-organic frameworks(MOFs)featuring stimuli-responsive structural transitions is often governed not only by the chemical composition and topology but also by orthogonal factors such as particle size,desolvation method,and history of the sample.A precise understanding of the mechanism behind such observations has been lacking up to now,and there are still substantial open questions concerning the impact of sample treatment *** DUT-8(M)family([M_(2)(2,6-ndc)2(dabco)]n,2,6-ndc=2,6-naphthalene dicarboxylate,dabco=1,4-diazabicyclo-[2.2.2]-octane),encompasses isostructural compounds based on Ni,Zn,Co,and Cu in the cluster node and is representative of pillared layer MOFs,often showing flexible *** this contribution,we discuss a possible explanation for the differences in flexibility observed in desolvated phases of DUT-8(Cu).Theoretical calculations and crystallographic data shed light on the preferred formation of interpenetrated confined closed pore phases in DUT-8(Cu)in contrast to DUT-8(Ni,Co,Zn)where the closed pore phases are formed.

Bemisia tabaci has a wide range of host plants. Due to its short-distance solid migratory ability, there is a phenomenon of migration and damage among plants in different seasons. Through the study of the population growth and decline rules of B. tabaci on different host plants and the prediction and forecast technology explores its sustainable prevention control technology. This article mainly discusses the research progress of B. tabaci forecasting, realizing the timely prevention and control of B. tabaci and comprehensive regional management, which can effectively reduce the population base of B. tabaci and reduce the number of pesticides used, which has a protective effect on the ecological environment.

Bemisia tabaci (Gennadius) (Homoptera: Aleyrodidae) is the most destructive invasive pests in agricultural production and has a high tolerance to heat. Heat shock proteins play an essential role in life activities such as growth and development, reproduction and diapause of B. tabaci. At the same time, they are also crucial in resisting adverse environments and in adaptive evolution. The expression of heat shock protein in B. tabaci is not only related to temperature, but also to the tolerance of the environment. After receiving external stimuli, the expression level can be increased or decreased to maintain the stability of cells in vivo. This paper reviews the classification, biological characteristics, biological functions, and research status of HSPs in recent years. This mini-review will provide helpful information related to the use of heat shock proteins to study the occurrence and damage of B. tabaci. This has important theoretical and practical significance for revealing Hsps in explaining the population expansion mechanism of B. tabaci invasion and predicting population dynamics.

Blood loss in peacetime is mainly due to the normal menstrual cycle in women or diseases with surgical intervention. In wartime, blood loss in military personnel is a characteristic sign of a closed or open injury of the body during internal or external bleeding. Access to clinical care for wounded military personnel injured on the battlefield is limited and has long delays compared to patients in peacetime. Most of the deaths of wounded military personnel on the battlefield occur within the first hour after being wounded. The most common causes are delay in providing medical care, loss of time for diagnosis, delay in stabilization of pain shock and large blood loss. Some help in overcoming these problems is provided by the data in the individual capsule, which each soldier of the modern army possesses;however, data in an individual capsule is not sufficient to provide emergency medical care in field and hospital conditions. This paper considers a project for development of a smart real-time monitoring wearable system for blood loss and level of shock stress in wounded persons on the battlefield, which provides medical staff in field and hospital conditions with the necessary information to give timely medical care. Although the hospital will require additional information, the basic information about the victims will already be known before he enters the hospital. It is important to emphasize that the key term in this approach is monitoring. It is tracking, and not a one-time measurement of indicators, that is crucial in a valid definition of bleeding.
