There is a global need to reduce greenhouse gas emissions to limit the extent of climate change.A better understanding of how our own activities and lifestyle influence our energy use and carbon emissions can help us enable changes in activities that can lead to reductions in carbon *** we discuss an approach based on examining carbon emissions from the perspective of the unit C,where 1 C is the CO_(2)from food a person would on average eat every *** approach shows that total CO_(2)emissions in China,normalized by the population,is 22.5 C while carbon emissions for a person in the US is 43.9 C.A better appreciation of our own energy use can be obtained by calculating carbon emissions from our own activities in units of C,for example for driving a car gasoline or electric vehicle a certain number of kilometers,using electricity for our homes,and eating different *** this information,we can see how our carbon emissions compare to national averages in different countries and make decisions that could lower our personal CO_(2)emissions.

韩国作为一个出口驱动型经济强国,其生活用纸行业是个罕见的例外,为净进口。但是,相比大多数发达经济体,韩国受到失业率和通货膨胀的影响较小,没有太多阻碍消费增长的问题,因此,生产商正在集中精力提高技术能力,而不是扩大规模。2023—2028年期间,韩国纸浆和纸板市场预计将以5.20%的复合年均增长率增长。一个重要因素是当地消费者对环保产品和包装的认识不断增强。2020年,韩国的纸张产量大约为1,163万t。

泰国:卫生纸需求正超越本地产能

中华纸业 2024年第6期45卷 25-27页

作者： bruce Janda 费雪国际

泰国作为一个统一国家的历史可以追溯到13世纪,目前本土仍在运营的许多卫生纸厂的历史可以追溯到20世纪40年代。20世纪70年代,泰国政府推出人口控制举措,开始控制人口增长,人口增长趋势发生明显变化,到目前,泰国已经出现了人口老龄化现象。

Damage to the spinal cord disrupts the electrically active nerve cells which normally transmit afferent and efferent signals,resulting in loss of motor,sensory,and autonomic *** treatments for spinal cord injury utilizing implanted spinal electrodes can be broadly classified into three different *** first of these approaches is“spinal stimulation”where electrodes,usually positioned above the level of injury,provide electrical stimulation to target and disrupt pain signals before they reach the *** second approach uses“activity-dependent neuro-technologies”,in which electrodes positioned below the level of injury initiate a complex spatiotemporal pattern of stimulation at the lumbar spinal cord to generate a walking gait in the limbs(Minev et al.,2015;Wagner et al.,2018).

作者： bruce Hoeneisen Universidad San Francisco de Quito Quito Ecuador

We compare observed with predicted distributions of galaxy stellar masses M* and galaxy rest-frame ultra-violet luminosities per unit bandwidth LUV, in the redshift range z=2 to 13. The comparison is presented as a function of the comoving warm dark matter free-streaming cut-off wavenumber kfs. For this comparison the theory is a minimal extension of the Press-Schechter formalism with only two parameters: the star formation efficiency, and a proportionality factor between the star formation rate per galaxy and LUV. These two parameters are fixed to their values obtained prior to the James Webb Space Telescope (JWST) data. The purpose of this comparison is to identify if, and where, detailed astrophysical evolution is needed to account for the new JWST observations.

We summarize several measurements of the dark matter temperature-to-mass ratio, or equivalently, of the comoving root-mean-square thermal velocity of warm dark matter particles v h rms ( 1 ) . The most reliable determination of this parameter comes from well measured rotation curves of dwarf galaxies by the LITTLE THINGS collaboration: v h rms ( 1 ) = 406 ± 69 m / s . Complementary and consistent measurements are obtained from rotation curves of spiral galaxies measured by the SPARC collaboration, density runs of giant elliptical galaxies, galaxy ultra-violet luminosity distributions, galaxy stellar mass distributions, first galaxies, and reionization. Having measured v h rms ( 1 ) , we then embark on a journey to the past that leads to a consistent set of measured dark matter properties, including mass, temperature and spin.
