Enhancement of seed germination in Macaranga peltata for use in tropical forest restoration

Journal of Forestry research 2014年第4期25卷 897-901页

作者： cassie r.rodrigues Bernard F.rodrigues Department of Botany Goa University Goa 403206 India

We used pre-sowing treatments v/z., soaking seeds in concen- trated sulphudc acid （CSA）, gibberellic acid （GA）, combined treatment of CSA ＋ GA and mechanical scarification to overcome seed dormancy and enhance synchronous germination of Macaranga peltata seeds. We analysed percent seed germination data by logistic regression and con- finned that except in GA treatment, time and acid concentration together were crucial for enhancing germination. The combination treatment of CSA and GA resulted in higher percent germination （up to 74%） than either treatment used separately, but produced defective seedlings （26%）. Mechanical scarification of seed coat had the greatest impact in enhanc- ing germination （78%） and reducing imbibition time （6 days） against the control （0%）. Germination studies and SEM analysis confirmed that seed germination in M. peltata was inhibited by seed coat dormancy.

Construction quality acceptance performance-related specifications for chip seals

Journal of Traffic and Transportation Engineering(English Edition) 2019年第4期6卷 337-348页

The research described herein details the establishment of a framework for construction quality acceptance performance-related specifications(PrS) for chip seal surface treatments. This paper establishes acceptance quality characteristics(AQCs) and relationships between the AQCs and related chip seal performance measures. This work is a critical step in developing PrS for constructed chip seal treatments and establishing suitable guidelines for the PrS. The main objective of this paper is to determine appropriate test methods to evaluate each defined AQC. The relationships that are established between the AQCs and chip seal performance are used to define performance ranges and threshold values for a particular performance measure. These performance ranges and threshold values then can be used to define pay factors for the constructed chip seal section. The threshold values and pay factors for each AQC described herein are preliminary recommendations and require further validation prior to implementation. However, this research demonstrates how these PrS would be utilized to ensure acceptable chip seal construction quality in the *** developed construction quality acceptance PrS framework uses the percent within limits(PWL) concept to determine whether a chip seal lot passes the PrS threshold values and whether the contractor receives full pay, is subject to a pay penalty, or fails the construction PrS and must correct the chip seal within the first year in service, which constitutes the typical warranty period for contracted chip seal ***, recommendations are made as to the next steps in the development and validation of these construction quality acceptance PrS that are needed for implementation by contractors and state roadway maintenance agencies.

What Are the Characteristics of Arabinoxylan Gels?

引用

Food and Nutrition Sciences 2018年第7期9卷 818-833页

作者： cassie Anderson Senay Simsek Cereal Science Graduate Program Department of Plant Sciences North Dakota State University Fargo USA

Arabinoxylan gels are commonly characterized to determine the feasibility of utilizing them in numerous applications such as drug delivery systems. The general characteristics of numerous types of arabinoxylan gels as well as their susceptibility to degradation are discussed in this manuscript. There are two main types of arabinoxylan: water-extractable and alkali-extractable. The physicochemical characteristics of the arabinoxylan determine its extractability and gelling characteristics. Gels can be created from numerous types of arabinoxylan including wheat (Triticum aestivum L.) and maize (Zea mays L.). These gels can also be developed with the addition of protein and/or β-glucan, which results in modified mechanical properties of the gels. To create a sound gel, arabinoxylan must be cross-linked, which is often done through ferulic acid. When this takes place, the gel developed is thermo-irreversible, unsusceptible to pH and electrolyte interactions, and does not undergo syneresis during storage. Despite these strengths, arabinoxylan gels can be broken down by the enzymes produced by Bifidobacterium, which is present in the human large intestine. After further development and research on these gels, they could be utilized for many purposes.

Can the International Classification of Functioning, Disability and Health (ICF) be used to understand risk factors for falls in older Australian women?

Purpose: To evaluate the relevance and accuracy of determining and predicting risk factors for falls in older women using the International Classification of Functioning, Disability and Health (ICF). Methods: We tested the accuracy of the ICF against risk of falls amongst 568 community dwelling participants of the Australian Longitudinal Survey on Women’s Health (ALSWH). We linked health-related variables to the ICF using ten linking rules. The logistic regression analysis evaluated the relationship between the variables and the outcome of falls. Self-report surveys measured daily functioning, health service use, medications, housing and social support. results: Variables aligned with the ICF components of body function, health conditions, environment, activity and participation (ADL/IADL), and general health were significantly associated with falls. Discussion and conclusion: Mapping ALSWH health-related data to ICF components identified significant risk factors for falls are related to health conditions, functional limitations and home hazards. Biopsycho-social approaches guided by the ICF framework are crucial for fall prevention.
