Comparison of two schemes for district cooling system utilizing cold energy of liquefied natural gas

Two schemes（scheme Ⅰ and scheme Ⅱ）for designing a district cooling system（DCS）utilizing cold energy of liquefied natural gas（LNG）are presented.In scheme Ⅰ,LNG cold energy is used to produce ice,and then ice is transported to the central cooling plant of the DCS.In scheme Ⅱ,return water from the DCS is directly chilled by LNG cold energy,and the chilled water is then sent back to the central plant.The heat transportation loss is the main negative impact in the DCS and is emphatically analyzed when evaluating the efficiency of each scheme.The results show that the DCS utilizing LNG cold energy is feasible and valuable.The cooling supply distance of scheme Ⅱ is limited within 13 km while scheme Ⅰ has no distance limit.When the distance is between 6 and 13 km,scheme Ⅱ is more practical and effective.Contrarily,scheme Ⅰ has a better economic performance when the distance is shorter than 6 km or longer than 13 km.

A narrative overview of utilizing biomaterials to recapitulate the salient regenerative features of dental-derived mesenchymal stem cells

Tissue engineering approaches have emerged recently to circumvent many limitations associated with current clinical practices.This elegant approach utilizes a natural/synthetic biomaterial with optimized physiomechanical properties to serve as a vehicle for delivery of exogenous stem cells and bioactive factors or induce local recruitment of endogenous cells for in situ tissue regeneration.Inspired by the natural microenvironment,biomaterials could act as a biomimetic three-dimensional(3D)structure to help the cells establish their natural interactions.Such a strategy should not only employ a biocompatible biomaterial to induce new tissue formation but also benefit from an easily accessible and abundant source of stem cells with potent tissue regenerative potential.The human teeth and oral cavity harbor various populations of mesenchymal stem cells(MSCs)with self-renewing and multilineage differentiation capabilities.In the current review article,we seek to highlight recent progress and future opportunities in dental MSC-mediated therapeutic strategies for tissue regeneration using two possible approaches,cell transplantation and cell homing.Altogether,this paper develops a general picture of current innovative strategies to employ dental-derived MSCs combined with biomaterials and bioactive factors for regenerating the lost or defective tissues and offers information regarding the available scientific data and possible applications.

A community resource for exploring and utilizing genetic diversity in the USDA pea single plant plus collection

Globally,pea(Pisum sativum L.)is an important temperate legume crop for food,feed and fodder,and many breeding programs develop cultivars adapted to these end-uses.In order to assist pea development efforts,we assembled the USDA Pea Single Plant Plus Collection(PSPPC),which contains 431 P.sativum accessions with morphological,geographic and taxonomic diversity.The collection was characterized genetically in order to maximize its value for trait mapping and genomics-assisted breeding.To that end,we used genotyping-by-sequencing—a cost-effective method for de novo single-nucleotide polymorphism(SNP)marker discovery—to generate 66591 high-quality SNPs.These data facilitated the identification of accessions divergent from mainstream breeding germplasm that could serve as sources of novel,favorable alleles.In particular,a group of accessions from Central Asia appear nearly as diverse as a sister species,P.fulvum,and subspecies,P.sativum subsp.elatius.PSPPC genotypes can be paired with new and existing phenotype data for trait mapping;as proof-of-concept,we localized Mendel’s A gene controlling flower color to its known position.We also used SNP data to define a smaller core collection of 108 accessions with similar levels of genetic diversity as the entire PSPPC,resulting in a smaller germplasm set for research screening and evaluation under limited resources.Taken together,the results presented in this study along with the release of a publicly available SNP data set comprise a valuable resource for supporting worldwide pea genetic improvement efforts.

Predicting the Potential Performance in P-Type SnS Crystals via Utilizing the Weighted Mobility and Quality Factor

The figure of merit ZT is the direct embodiment of thermoelectric performance for a given material.However,as an indicator of performance improvement,the only ZT value is not good enough to identify its outstanding inherent properties,which are highly sought in thermoelectric community.Here,we utilize one powerful parameter to reveal the outstanding properties of a given material.The weighted mobility is used to estimate the carrier transports of p-type SnS crystals,including the differences in doping level,carrier scattering and electronic band structure.We analyze the difference in carrier scattering mechanism for different crystal forms with the same doping level,then evaluate and confirm the temperature-dependent evolution of electronic band structures in SnS.Finally,we calculate the quality factor B based on the weighted mobility,and establish the relationship between ZT and B to further predict the potential performance in p-type SnS crystals with low cost and earth abundance,which can be realized through taking advantage of the inherent material property,thus improving B factor to achieve optimal thermoelectric level.

The comprehensive utilization and environment-friendliness of processes for recovering fresh water or valuable salt from seawater, salt-lakes, or mineral deposits are of utmost importance for sustainable development.One primitive sustainable process for recovering salt from sodium-sulfate-type brine in Yuncheng salt lake had been considered one of the greatest inventions of ancient China, however, the replaced process of mass extraction of single Na_2SO_4 in recent years, has reduced a large amount of residual brine.In this research, relying on the salt-forming diagram in the non-equilibrium state, the technical secrets of ancient salt processes were uncovered, and a new comprehensive utilization system was proposed and tested experimentally.The new system includes a vacuum salt-making process and a normal pressure kieserite process, which can gradually eliminate the existed waste liquid and aid in the sustainable development of the Yuncheng salt-lake.The continuous experiment of salt-making process running stably in the double salt region without double salt formation, which proves the feasibility of salt-forming diagram applied in industrial process.Thus salt-forming diagram would be extremely valuable to industry process design and control, especially, the treatment of concentrated brine.

Utilizing Dominant Early Maturity Genes of Sterile Line UP-3s in Hybrid Rice Breeding to Avoid High Temperature Season

A new sterile line UP-3s, which carries the Dominant Early Maturity Gene (DEMG), was bred on the farm of University of Arkansas at Pine Bluff (UAPB). UP-3s and two check sterile lines, Jin23-A and Xie-A which do not carry the Dominant Early Maturity Gene, were crossed with a group of different maturity restorer lines, PB-1R, PB-5R,PB11, PB-13R, PB-20, PB-21, PB-22R, and PB-23R. Eighteen new hybrid rice combinations of these crosses were then tested at UAPB in 2012 and 2013. The results showed that panicle differentiation (PD) of hybrids from female parent UP-3s (DEMG) crossed with the 8 male parents, were earlier than the hybrids from female parent Jin23-A or Xie-A crossed with the 8 male parents. The PD of these earlier hybrids was before Jun 25 and heading was before July 20. Early PD and heading avoided the high temperature (over 34&degC) period which usually occurs after July 20 in Arkansas. The yields of these earlier maturity hybrids with female parent UP-3s were higher than those of the late maturity hybrids thatwereF1 progeny of sterile lines Jin23-A or Xie-A (these two female parent checks with non-DEMG). These results showed that the DEMG sterile line UP-3s can be adopted in making crosses with later maturity restorer lines to obtain earlier maturity hybrids to avoid the high temperature period in Arkansas.
