Two paths, one goal: mechanism of calcium homeostasis to balance plant growth and immunity

引用

Science China Life Sciences 2025年第1期 306-308页

作者： Aziz ul Ikram Yanping Jing Huan Chen Jian Chen International Genome Center Jiangsu University Joint Center for Single Cell Biology School of Agriculture and BiologyShanghai Jiao Tong University

Calcium(Ca2+) is an essential nutrient and a cellular signal in plants. The level of free Ca2+in the apoplast is ～10,000-fold higher than that in the cytoplasm at the resting state. This large Ca2+level gradient across the membrane between the interior and exterior can cause Ca2+overload and toxicity. Plants have evolved mechanisms to export Ca2+out of the cytoplasm or store it in intracellular organelles, such as endoplasmic reticulum（ER）, mitochondria, and vacuole.

Thermodynamic properties of ZnSe under pressure and with variation in temperature

引用

Chinese Physics B 2017年第9期26卷 144-147页

作者： Najm ul Aarifeen A Afaq Center of Excellence in Solid State Physics University of the PunjabLahore 54590Pakistan

The thermodynamic properties of Zn Se are obtained by using quasi-harmonic Debye model embedded in Gibbscode for pressure range 0–10 GPa and for temperature range 0–1000 K. Helmholtz free energy, internal energy, entropy,Debye temperature, and specific heat are calculated. The thermal expansion coefficient along with Gruneisen parameter are also calculated at room temperature for the pressure range. It is found that internal energy is pressure dependent at low temperature, whereas entropy and Helmholtz free energy are pressure sensitive at high temperature. At ambient conditions,the obtained results are found to be in close agreement to available theoretical and experimental data.

Effects of temperature and pressure on thermodynamic properties of Cd_(0.25)Zn_(0.75)Se alloy

引用

Chinese Physics B 2017年第12期26卷 216-220页

作者： Najm ul Aarifeen A Afaq Center of Excellence in Solid State Physics University of the Punjab Quaid e Azam Campus Lahore-54590 Pakistan

Thermodynamic properties of Cd0.25Zn0.75Se alloy are studied using quasi harmonic model for pressure range of 0 GPa-10 GPa and temperature range 0 K-1000 K. The structural optimization is obtained by self-consistent field calculations and full-potential linearized muffin-tin orbital method with GGA＋U as an exchange correlation functional where U=2.3427 eV is Hubbard potential. The effects of temperature and pressure on bulk modulus, Helmholtz free energy, internal energy, entropy, Debye temperature, Grüneisen parameter, thermal expansion coefficient, and heat capacities of the material are observed and discussed. The bulk modulus, Helmholtz free energy, and Debye temperature are found to be decreased on increasing temperature while there is an increasing behavior with rise of the pressure. Whereas the internal energy has increasing trend with the rise in temperature and it almost remains insensitive to pressure. The entropy of the system increases （decreases） with rise of pressure （temperature）.

A significant body of literature has examined the location decision-making of creative industry ***,research on the nexus between design creative industries and the built environment remains *** key finding of this qualitative research is that design creative industries are mostly the users of the inner city's former industrial buildings that are occupied on leases from property owners who are responsible for the initial physical *** condition is largely due to the low level of property ownership among this group and the lack of incentive to invest additional capital to their business ***,design creative industries cannot be conceptualized as leading actors in urban redevelopment or initiators of urban transformation on a large ***,they represent a latent demand for physical space and a rich source of inspiration and creative *** this regard,design creative industries play a key role as enablers of postindustrial real estate development driven by proactive property developers who transform former industrial buildings into a new form of revenue-generating urban commodities.
