Abstract

Based on the time series of ecological footprint (EF) in Jilin Province from 1994 to 2003, the relationship models of EF, ecological budget, and EF intensity with urbanization level were established. The results showed that in Jilin Province, there existed significant correlations of EF, ecological budget, and EF intensity with urbanization level. Along with the development of urbanization, the EF in the Province increased from 1.59 hm2 x cap(-1) in 1994 to 2.23 hm2 x cap(-1) in 2003, which was mainly affected by the process of urbanization and the proportion of tertiary industry. The EFs of built-up land, pasture and fossil fuel land changed more markedly, among which, the EFs of pasture and fossil fuel land were mainly affected by domestic consumption, while that of built-up land was mainly affected by the GDP per capita and the proportion of tertiary industry. Owing to the increase of domestic consumption, the ecological deficit increased from 0.319 hm2 cap in 1994 to 0.923 hm2 cap(-1) in 2003. The changes in ecological budget of pasture and fossil fuel land were more remarkable. Under the effects of the optimization of economic structure and consumption structure, the EF intensity in the Province decreased from 4.14 hm2 x (...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
