THE MANUFACTURE OF KRAFT PULP BY SODIUM HYDROXIDE PROCESS

Journal of the Japanese Technical Association of the Pulp and Paper Industry, 1949
It is pointed out that the pulp made by this process is quite suitable for making wrapping and bag paper as well as vulcanized fiber substitute, paper container etc. The preparation of cooking liquor is described and particularly, cooking operation and gas recovery are explained with experimental data. The following points are made clear 1) Composition

Offspring Global DNA Methylation is not Affected by Parental Developmental Stress Experience in a Passerine Species

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Rapid phenotypic change may be mediated by intergenerational transmission of early developmental experiences. In birds, exposure to glucocorticoids during early development can alter global DNA methylation and gene expression. However, DNA methylation is labile, and it is currently unclear whether the impacts of stress suffered during juvenile

Preparing Prospective Counselors for Classroom‐Based Career Guidance Using Video Vignettes—Mechanisms and Effects

Journal of Employment Counseling, EarlyView.
ABSTRACT Career guidance in schools is often delivered by counselors who take on instructional roles. Video vignettes are widely used in teacher education. We developed vignettes for counselor training in classroom‐based guidance in Germany. This study examines how prospective counselors engage with these vignettes and how this relates to changes in ...

Palatal donor site wound healing following mucogingival surgery using amnion‐chorion membrane: A randomized controlled clinical trial

Journal of Periodontology, EarlyView.
Abstract Background Free soft tissue autografts (FSTA) harvested from a patient's palate are frequently associated with significant postoperative morbidity. Several wound dressings have been applied to the palatal donor site with the aim of reducing postoperative complications and improving wound healing.

Straw Return Combined With Nitrogen Fertilizer Application Improve Nitrogen Utilization Efficiency by Regulating Soil Physical and Chemical Properties in Spring Maize

Land Degradation &Development, EarlyView.
ABSTRACT Straw return (SR) and controlled‐release nitrogen fertilizers application can improve soil structure, enhance soil water retention, and promote crop growth. However, the mechanisms through which SR and controlled‐release nitrogen fertilizers application jointly modulate soil physical and chemical properties remain unclear.

Low‐Hysteresis Cellulose‐Based Hydrogels for Strain Detecting

Macromolecular Rapid Communications, EarlyView.
Low‐hysteresis hydrogel with high cellulose content is prepared. The modified cellulose is prepared through a sequential periodate oxidation and borohydride reduction process. The hydrogel can be used as a strain sensor with a gauge factor of 1.1 in the 0%–300% sensing range.

Seed co‐occurrence caused by shared frugivores leaves a long‐lasting signal in the spatial co‐occurrence among plants

Oikos, EarlyView.
By dispersing seeds, frugivorous animals affect spatial co‐occurrence of plants, ultimately influencing plant community dynamics. Frugivorous animals are intrinsically involved in plant community dynamics, by dispersing seeds of fleshy‐fruited plants and influencing their spatial co‐occurrence.
