Abstract:

The aim of this research was to determine the optimum planting density for the production of high-quality cut flowers with desirable characteristics. 25 single-stem ornamental sunflower genotypes were planted at different densities and evaluated for flowering time, flower diameter, and stem circumference and length over a two-year production cycle. Three spacing patterns were used: 25 × 25 cm, 30 × 30 cm, and 70 × 30 cm, which led to the planting densities of 160 000, 90 000, and 60 000 plants/ha, respectively. The plant density had the most important effect on the stem circumference, flower d

Abstract:

Despite evidenced challenges compared to non-rural areas, rural communities are in a unique position to help address recent national demands for renewed STEM emphasis in schools (Saw & Agger, 2021). This study utilizes interviews from five rural educators who participated in a three-week STEM learning camp to discuss: 1) how teachers perceive the effectiveness of STEM learning opportunities at increasing student aspirations in STEM fields, and 2) what support and resources teachers need to provide more quality STEM learning opportunities. Learning experiences focused on aerospace engineeri

Abstract:

STEM Education is one of the elements that need to be applied in 21st Century Education (PAK- 21). However, STEM Education is given less attention by many early childhood education (ECE) teachers due to various factors that influence its implementation in kindergartens such as lack of exposure to STEM Education information and many more. This study was conducted to see the perceptions of kindergarten teachers on how they think about the importance of STEM Education itself in order to ensure the quality of children's learning can be achieved through STEM Education at the early schooling level.

Abstract:

Tissue-specific stem cells persist for a lifetime and can differentiate to maintain homeostasis or transform to initiate cancer. Despite their importance, there are no described quality assurance mechanisms for newly formed stem cells. We observed intimate and specific interactions between macrophages and nascent blood stem cells in zebrafish embryos. Macrophage interactions frequently led to either removal of cytoplasmic material and stem cell division or complete engulfment and stem cell death. Stressed stem cells were marked by surface Calreticulin, which stimulated macrophage interactions.

ABSTRACT The essay objective was to correlate lignin content resulting from tigmomorphogenesis induced by stem swaying with survival and post-planting growth of P. taeda seedlings. Seedlings were subjected to daily frequencies (0, 5, 10, 20 and 40 movements) of stem swaying for 60 days. By the end of the treatments, we determined lignin content of below and aboveground seedling tissues. Four replicates per treatment were planted in a area cultivated with pines. Ninety days after planting, survival and increments of seedling height, stem diameter and stem volume were quantified. Application of

Abstract:

Hematopoietic stem cell transplantation (HSCT) is an established treatment for a variety of malignant diseases, as well as a small proportion of non-malignant disorders. The treatment before the HSCT (called conditioning) can be either myeloablative (MAC) or given with reduced intensity (RIC). MAC is associated with high toxicity due to high doses of chemotherapy with or without total body irradiation (TBI), and is used in both autologous and allogeneic HSCT. In autologous HSCT the patient is the donor, and in allogeneic HSCT the donor is a sibling or an unrelated donor. RIC regimens are assoc

Abstract:

Regenerative medicine and cell therapies hold great potential to treat a variety of medical conditions. Product characterisation of these therapies is particularly difficult as they pose regulatory challenges due to donor heterogeneity and the lack of standardised lot release tests that can reliably predict in vivo function. Human mesenchymal stem cells (hMSCs), also called multipotent stem cells or mesenchymal stromal cells, are a viable option in cell therapies due to their immunosuppressive and pro-angiogenic functions. Currently there are no standardised methods or potency assays to quanti

Abstract:

Background: Sleep disruption is one of the most commonly reported quality of life concerns among cancer patients who have undergone hematopoietic stem cell transplantation (HSCT). Despite the high percentage of patients reporting sleep concerns, relatively little research has characterized sleep problems or explored relationships with psychological factors. In addition, no studies have used actigraph technology to characterize sleep issues among transplant recipients. Method: Autologous HSCT recipients who were 6 to 18 months post-transplant were invited to participate. Patients completed self

Abstract:

Abstract Trees in continuous cover forestry (CCF) typically form very narrow rings at young ages in suppressed positions but can grow very quickly at older ages in dominant positions, maintaining long-lived crowns. CCF trees have slightly higher mean wood density in stems than rotation forestry (RF) trees. CCF trees have better fiber properties for pulp than RF trees. CCF trees have a relatively short stem section of small dead knots in sawn timber. CCF trees have a relatively long section of large green knots in sawn timber. Sawn goods produced from spruce logs yielded with the selection system do not differ markedly from those from RF. The application of a shelterwood system with overstorey retention for Scots pine facilitates the production of very high-grade timber.
