Authors: Shahira Samsudin Nurul , Aminalâ€™lah Nuraliah , Syazni Kamarudin Ahmad , Huda Nurul , . . 
Published: July 2024

The objective of this study was to compare the physicochemicalÂ properties (cooking yield, folding test, gel strength, expressible moisture, texture profile analysis, and color) of minced fish containing quail bone gelatin (QBG), commercial bovine gelatin (CBG), or commercial fish gelatin (CFG). QBG was prepared using two acid pretreaments: hydrochloric acid (QBGHCl) and citric acid (QBGc.a). The cooking yield of minced fish gels improved from 94.23% to 96.17â€“98.48% by the addition of gelatin. Addition of QBGHCl, QBGc.a, CBG, and CFG improved the folding test result from 1.00 to 2.00, reduced expressible moisture from 37.90% to 29.59, 30.19, 27.81, and 36.73%, respectively, and improved gel strength from 69.42 g.cm to 92.17, 96.5, 155.30, and 99.73 g.cm, respectively. Addition of gelatin also increased the hardness and decreased the whiteness of fish minced gels. Thus, the addition of QBG has potential as an alternative gelatin source for improving the physicochemical properties of minced fish.Â Â

Published: July 2024

Propolis is a sticky substance made up of mixture of plant resin, wax and bee saliva. Propolis has been used in various health related problems as well as cosmetic ingredient.Â This work was evaluating chemical fingerprint of Malaysian stingless bee propolis produced by two species, Heterotrigona itama (HI) and Geniotrigona thoracica (GT). Chemical fingerprint derived from fingerprint region (FR) of ATR-FTIR dataset of two types of extract, methanol (MHI, MGT) and ethanol (EHI, EGT). Principal component analysis and hierarchical cluster analysis was employed to discriminate the two species. The total variances account for FR was 95.63 % (PC1 = 54.01 %, PC2 = 41.61 %). EHI and EGT clustered closely between them and separately from MHI and MGT. HCA conform the grouping by PCA. GC-MS analysis revealed the presence of 20 different phytochemicals in methanol, while ethanol extract shown only 17 different phytochemicals of GT propolis. Meanwhile, 24 different phytochemicals were identified in methanol extract and 13 compounds presence in ethanol extract from propolis samples collected by HI species. Based on the good separation observed in both spectroscopic and chromatographic data, it seems reasonable to use chemical fingerprint coupled with chemometric analysis to differentiate two different species of stingless bee propolis. The findings from this study can be used as identification, classification and quality control methods for the profiling of propolisÂ Â

Architecture as an order of human society should correspond to the functional, aesthetic, time needs and financial capabilities of all strata of society. Â In this article described the main functional division of industrial objects system.When designing industrial objects, the main task of the architect is to create a construction that would be most suitable for the technological process of production. That is, he must take into account all the factors and conditions that govern the hierarchical structure of the industry and design a factory or plant that would be a modern element of the production system. Back in 1923 A. Rozenberg, in his book "Philosophy of Architecture", wrote: "It is impossible to properly design an architectural structure, not knowing precisely the organization of the process for which it is intended. And therefore, the deeper the architect will penetrate into its details of the organization, the more accurate it will clear itself to all the requirements imposed on the organization of the process, its course, the properties of the individual components of the mass of the process, and will establish the scheme of the process - that the conformity of the architectural structure to the process taking place in it will be more perfect, and the better will be the construction.

Under current conditions the progressively increasing anthropogenic pressure on land resources and significant changes in the structure of land tenure require the creation and immediate implementation of a system for surveillance and inspection the use and condition of lands in order to identify changes on-time, to asses them prevent and eliminate the consequences of negative processes occurring on the land tenure territory. The task of effective use of land is not properly performed due to the lack of reliable information about its condition and use. Such information can be obtained through the creation and operation of the ongoing system of the land condition state monitoring based on geoinformation technologies. This study is directed at determining the influence and correlation of the landscape spatial development with elements of the territory organization using the criterion of agricultural crops productivity with geographic information system (GIS).Â The necessity of the analysis is connected with the detection of cyclicality, regularity, the influence direction of the territory organization elements on the landscape spatial development, which will make it possible to apply the most cost-effective and environmentally sound ways of using particular areas.Â Â Â
