Basics of energy-efficiency of renovation of existing office buildings and restoration of listed buildings

The article highlights the basics of energy-efficiency of renovation of existing office buildings, adaptive reuse of buildings for the office function and energy restoration of listed buildings. The advantages of renovation over the new construction in terms of sustainability and reduction of energy consumption were considered. Three different approaches to energy renovation were studied, depending on the location of the buildings and their listing status: existing buildings located outside the historical areas of the cities; existing buildings located in the historical areas of cities; and listed buildings. Principles and methods of energy-efficient renovation of existing office buildings and energy restoration of listed buildings were reviewed. As for the listed buildings, during the modernization or restoration aiming the increase of energy efficiency - the material component of the buildings, which determines its authenticity, should be preserved as much as possible. Regarding the renovation of existing not listed buildings but located in the historical areas - the height, scale, plastic solution, character, finishing materials, etc. must be preserved. It has to be done in order to preserve the identity and the character of the historically inherited environment of a certain area of the city. A list of passive and active design strategies for energy consumption reduction of office buildings during renovation and energy-efficient restoration was provided. Including following passive strategies: facades and roof insulation; low infiltration values; optimization of the glazing ratio; optimal selection of glazing types; use of solar shading devices; use of daylight; passive heating due to solar radiation in winter; use of natural ventilation; integration of greenery into the building; use of internal structures of the building with high heat capacity; use of "double" glass facades, etc. The limitations that reduce the possibilities of energy modernization of listed buildings were considered. Ukrainian and foreign case-studies of renovation, adaptive reuse and restoration were researched and critically analyzed.

Flow field and sediment removal in a stormwater sump utilizing internal structures.

This study investigated the hydraulic characteristics of stormwater sumps and their design optimization for sediment retention using physical experiments. Particle image velocimetry was utilized to measure the flow field, and the use of internal structures was investigated for improving solids retention. Results indicate that these internal structures can significantly improve the sediment removal efficiency of suspended solids with an average size of 125 μm, resulting in an efficiency improvement of 20-30%. Additionally, a modified Péclet number was proposed to more accurately evaluate the sediment removal efficiency of stormwater sumps, and recommendations were provided for further improving and optimizing sump design. This study provides insights into the hydraulic characteristics of stormwater sumps and has important implications for optimizing and designing particle removal systems for various industrial and environmental applications.

Comprehensive analysis of the internal structure and firmness in American cranberry (Vaccinium macrocarpon Ait.) fruit.

BackgroundCranberry (Vaccinium macrocarpon L.) fruit quality traits encompass many properties. Although visual appearance and fruit nutritional constitution have usually been the most important attributes, cranberry textural properties such as firmness have recently gained importance in the industry. Fruit firmness has become a quality standard due to the recent demand increase for sweetened and dried cranberries (SDC), which are currently the most profitable cranberry product. Traditionally, this trait has been measured by the cranberry industry using compression tests; however, it is poorly understood how fruit firmness is influenced by other characteristics.ResultsIn this study, we developed a high-throughput computer-vision method to measure the internal structure of cranberry fruit, which may in turn influence cranberry fruit firmness. We measured the internal structure of 16 cranberry cultivars measured over a 40-day period, representing more than 3000 individual fruit evaluated for 10 different traits. The internal structure data paired with fruit firmness values at each evaluation period allowed us to explore the correlations between firmness and internal morphological characteristics.ConclusionsOur study highlights the potential use of internal structure and firmness data as a decision-making tool for cranberry processing, especially to determine optimal harvest times and ensure high quality fruit. In particular, this study introduces novel methods to define key parameters of cranberry fruit that have not been characterized in cranberry yet. This project will aid in the future evaluation of cranberry cultivars for in SDC production.

Registration of in vivo prostate MRI and pseudo‐whole mount histology using Local Affine Transformations guided by Internal Structures (LATIS)

To present a novel registration approach called LATIS (Local Affine Transformation guided by Internal Structures) for coregistering post prostatectomy pseudo-whole mount (PWM) pathological sections with in vivo MRI (magnetic resonance imaging) images. Thirty-five patients with biopsy-proven prostate cancer were imaged at 3T with an endorectal coil. Excised prostate specimens underwent quarter mount step-section pathologic processing, digitization, annotation, and assembly into a PWM. Manually annotated macro-structures on both pathology and MRI were used to assist registration using a relaxed local affine transformation approximation. Registration accuracy was assessed by calculation of the Dice similarity coefficient (DSC) between transformed and target capsule masks and least-square distance between transformed and target landmark positions. LATIS registration resulted in a DSC value of 0.991 ± 0.004 and registration accuracy of 1.54 ± 0.64 mm based on identified landmarks common to both datasets. Image registration performed without the use of internal structures led to an 87% increase in landmark-based registration error. Derived transformation matrices were used to map regions of pathologically defined disease to MRI. LATIS was used to successfully coregister digital pathology with in vivo MRI to facilitate improved correlative studies between pathologically identified features of prostate cancer and multiparametric MRI.

A Review on the Collection, Preservation and Systematic Techniques in Phlebotominae

The aim of present study is to discuss the taxonomic and biological history and significance of Phlebotominae sand flies giving emphasis on their collection, preservation and identification of new species as well as differentiation of male and female. Several species of Phlebotominae sand flies are known throughout the world including India. These Phlebotominae sand flies are economically important natural enemies of human beings and cause Kala-azar and visceral leishmaniasis. This causes a lot of deaths. Taxonomy plays an important role in identifying these tiny insects accurately. The accurate identification is important to apply relevant control measures. A wrong identification may lead to misleading results and may upset the entire control strategy. From the start of sand fly research various methods for collection and identification were used. In the early twentieth century, the use of internal structures particularly, cibarium, pharynx and spermathecae was introduced as taxonomic characters. The identification of female sand flies was always found to be difficult and hence scanty work on females are available. Recently female external as well as internal genital structures are used for their identification. Another important character is the genital filament/spermathecal duct ratio which could be a good point for taxonomic differentiation of male and female Phlebotominae sand flies. The detailed study of some biologically important structures of sand flies e.g., mouthparts and reproductive organs both internal as well as external have led to the introduction of few new taxonomic characters.
