Abstract: This research aims to analyze the impact of Janti Flyover Construction toward the growth of layout at Janti Urban Area, including structured space, open space, and linkage. Method used for data collecting are observation, air photograph monitoring, and interview, whereas the analysis method is qualitative description, which is the superimposed method of two layers, that are the layout condition before and after flyover construction. The result shows that the impact of Janti Flyover construction can be seen on building mass (solid), the increasing number of open spaces, including the road network, parking place, and park, whereas the relation between spaces, visually and structurally, can be seen on the growth of buildings which have new shapes and styles, therefore the performance of the overall building does not have a proportional shape. Considering Janti Street at the collective relation, its role is getting stronger as the main frame road network.Keywords: Flyover construction, layout changing, Janti AreaAbstrak: Penelitian ini bertujuan untuk menganalisis pengaruh pembangunan Jalan Layang Janti terhadap perkembangan tata ruang Kawasan Janti, meliputi ruang terbangun, ruang terbuka, serta hubungan antar ruang (“linkage”).

Sediment Mixing

Previous studies of the effects of manholes on longitudinal dispersion has concentrated on the spreading of solutes. This papers presents new data describing the influence of a surcharged and free-flowing manhole structure on the longitudinal dispersion of a fine suspended material. The effects of benching within the manhole structure are also illustrated. Laser Induced Fluorescence (LIF) techniques have been used to provide a qualitative description of the mixing processes present within a surcharged manhole. Nephelometric results have provided estimates of the parameters required to simulate the mixing effects using either increase in variance or aggregated dead zone techniques. A preliminary attempt at describing these observations using available software is discussed and recommendations for future developments are made.

Polycyclic Aromatic

Polycyclic aromatic hydrocarbons (PAH) are a prominent substance class with a variety of applications in molecular materials science. Their electronic properties crucially depend on the bond topology in ways that are often highly non-intuitive. Here, we study, using density functional theory, the triplet states of four biphenylene-derived PAHs finding dramatically different triplet excitation energies for closely related isomeric structures. These differences are rationalised using a qualitative description of Clar sextets and Baird quartets, quantified in terms of nucleus independent chemical shifts, and represented graphically through a recently developed method for visualising chemical shielding tensors (VIST). The results are further interpreted in terms of a 2D rigid rotor model of aromaticity and through an analysis of the natural transition orbitals involved in the triplet excited states showing good consistency between the different viewpoints. We believe that this work constitutes an important step in consolidating these varying viewpoints of electronically excited states.

ABSTRACT Objective: The British Columbia Farmers’ Market Nutrition Coupon Program (FMNCP) provides low-income households with coupons valued at $21/week for 16 weeks to purchase healthy foods in farmers’ markets. Our objective was to explore FMNCP participants’ experiences of accessing nutritious foods, and perceived program outcomes. Design: This study used qualitative description methodology. Semi-structured interviews were conducted with FMNCP participants during the 2019 farmers’ market season. Directed content analysis was used to analyse the data whereby the five domains of Freedman et al’s framework of nutritious food access provided the basis for an initial coding scheme. Data that did not fit within the framework’s domains were coded inductively. Setting: One urban and two rural communities in British Columbia, Canada. Participants: 28 adults who were participating in the FMNCP. Results: Three themes emerged: Autonomy and Dignity; Social Connections and Community Building; and Environmental and Programmatic Constraints. Firstly, the program promoted a sense of autonomy and dignity through financial support, increased access to high-quality produce, food-related education and skill development, and mitigating stigma and shame. Secondly, shopping in farmers’ markets increased social connections and fostered a sense of community. Finally, participants experienced limited food variety in rural farmers’ markets, lack of transportation, and challenges with redeeming coupons. Conclusions: Participation in the FMNCP facilitated access to nutritious foods and enhanced participants’ diet quality, well-being and health. Strategies such as increasing the amount and duration of subsidies, and expanding programs may help improve participants’ experiences and outcomes of farmers’ market food subsidy programs.

Abstract Temperature is one of the basic factors influencing physical and structural properties of rocks. A quantitative and qualitative description of this influence becomes essential in underground construction and, in particular, in the construction of various underground storage facilities, including nuclear waste repositories. The present paper discusses the effects of temperature changes on selected mechanical and structural parameters of the Strzelin granites. Its authors focused on analyzing the changes of granite properties that accompany rapid temperature changes, for temperatures lower than 573ºC, which is the value at which the β - α phase transition in quartz occurs. Some of the criteria for selecting the temperature range were the results of measurements carried out at nuclear waste repositories. It was demonstrated that, as a result of the adopted procedure of heating and cooling of samples, the examined rock starts to reveal measurable structural changes, which, in turn, induces vital changes of its selected mechanical properties. In particular, it was shown that one of the quantities describing the structure of the rock - namely, the fracture network - grew significantly. As a consequence, vital changes could be observed in the following physical quantities characterizing the rock: primary wave velocity (vp), permeability coefficient (k), total porosity (n) and fracture porosity (η), limit of compressive strength (Rσ1) and the accompanying deformation (Rε1), Young’s modulus (E), and Poisson’s ratio (ν).

Factors Affecting

This paper applies fractal theory to research of green space in megacity parks due to the lack of a sufficient qualitative description of the scale structure of park green space, a quantifiable evaluation system, and operable planning methods in traditional studies. Taking Beijing, Shanghai, Guangzhou, and Shenzhen as examples, GIS spatial analysis technology and the Zipf model are used to calculate the fractal dimension (q), the goodness of fit (R2), and the degree of difference (C) to deeply interpret the connotation of indicators and conduct a comparative analysis between cities to reveal fractal characteristics and laws. The research results show that (1) the fractal dimension is related to the complexity of the park green space system; (2) the fractal dimension characterizes the hierarchical iteration of the park green space to a certain extent and reflects the internal order of the scale distribution; (3) the scale distribution of green space in megacity parks deviates from the ideal pyramid configuration; and (4) there are various factors affecting the scale structure of park green space, such as natural base conditions, urban spatial structure, and the continuation of historical genes working together. On this basis, a series of targeted optimization strategies are proposed.

Objectives: The ideal clinical model to deliver palliative care to patients with advanced kidney disease is currently unknown. Internationally, ambulatory kidney palliative care clinics have emerged with positive outcomes, yet there is limited data from the United States (US). In this exploratory study we report perceptions of a US-based ambulatory kidney palliative care clinic from the perspective of patient and caregiver attendees. The objective of this study was to inform further improvement of our clinical program. Methods: Semi-structured interviews were conducted to elicit the patient and caregiver experience. Eleven interviews (8 patients with chronic kidney disease stage IV or V and 3 caregivers) were analyzed using qualitative description design. Results: We identified 2 themes: “Communication addressing the emotional and physical aspects of disease” and “Filling gaps in care”; Subthemes include perceived value in symptom management, assistance with coping with disease, engagement in advance care planning, program satisfaction and patient activation. Significance of Results: Qualitative analysis showed that attendees of an ambulatory kidney palliative care clinic found the clinic enhanced the management of their kidney disease and provided services that filled current gaps in their care. Shared experiences highlight the significant challenges of life with kidney disease and the possible benefits of palliative care for this population. Further study to determine the optimal model of care for kidney palliative care is needed. Inclusion of the patient and caregiver perspective will be essential in this development.
