Published: June 2023

Abstract
In this paper, the quick freezing characteristics of incomplete gelatinized potato starch gels with 8 % concentration and its regeneration characteristics were studied. The results showed that the glass transition temperatures of the gel was −4.87 °C. The content of free water (T
24) in the gel decreased gradually during the quick-freezing process, but was still relatively high (80.18 %) when the central temperature reached −3 °C. The gel had not frozen on a large scale at central temperature −3 °C. The gel showed the highese gel strength (60.25 g) and the highest crystallinity (17.24 %) when aged at a low temperature (−3 °C) for 3 days and the gel strength increased with the decrease of storage temperature during aged at −3 °C to 3 °C. Scanning electron microscopy showed that the gel network was relatively intact when the gel stored at −3 °C for 1 day to 3 days.

Additive manufactured parts produced by selective laser sintering technology: porosity formation mechanisms
Authors: Morano Chiara , Pagnotta Leonardo 
Published: June 2023

Abstract
Additive manufacturing represents a powerful tool for the fabrication of parts with complex shapes by the deposition and the consolidation of materials as opposed to subtractive manufacturing methodology. Selective laser sintering (SLS), one of the most popular powder bed fusion (PBF) technologies for thermoplastic part production, has demonstrated extensive applications in various industrial sectors. The process involves the deposition of homogeneous powder layers and employs a laser source to selectively melt a powder bed according to a CAD model. Due to its layer-by-layer nature, voids and pores are inevitably introduced in the fabricated thermoplastic parts. Porosity represents one of the major limitations of this technology being one of the main causes of the variation of the mechanical properties. With the intention of providing support for reducing the porosity and thus increasing the quality and performance of the final product, in this paper, a brief review was carried out focusing on the SLS process parameters and their interaction with the porosity of the product. In addition, an in-depth look was given to the mechanisms of formation and consolidation of pores within parts made of polymeric material.
Efficient and reliable detection of rhodamine B using SERS from silver-decorated photonic crystal silicon nanoscale pores

Porous silicon photonic crystal (PSi PhC) decorated with silver nanoparticles (AgNPs) is shown to provide a new substrate for the improvement of SERS. AgNPs are obtained through immersion of PSi PhC samples in AgNO3 solutions and successive thermal annealing. The nanocomposite material generated by adding AgNPs inside the silicon nanoscale pores, integrates the ability of metal surfaces to amplify Raman scattering signals and an enlarged surface area. Besides, PhC structure formed by multilayer PSi increases interaction time of light and matter of the multilayer structure. The experimental results show that the AgNPs-decorated PSi PhC has the largest Raman intensity in comparison with other SERS substrates based on Si. The enhancement of Raman signals also reduces the threshold of the detection down to below 10-10 M. The analytical enhancement factor of AgNPs/PSi PhC SERS substrate for the detection of Rhodamine B (RhB) reaches 1010. This proposed AgNPs/PSi PhC SERS substrate could serve as a potential candidate for detecting RhB in foodstuffs at very low concentrations.

The Ba Lat estuary is part of the downstream stretch of the Red River Delta, the second-largest Delta in Vietnam and the 12th largest in the world. This study analyses GAT borehole sediments in the Ba Lat estuary area to assess environmental changes during the Late Pleistocene - Holocene period. This entailed detailed analyses of 70 m-deep borehole data from the Ba Lat estuary area, including structural analysis of 70 m-deep sediment core samples, 230 samples of grain size, 49 samples of Foraminifera, five samples of petrographic thin slices, and four samples of radiocarbon dating.
The data reveal nine sedimentary facies, including river channel sand facies, floodplain clayey silt facies, tidal flat sandy-silty facies, bay clayey silt facies, pro-delta clayey silt facies, delta front sandy-silty clay facies, mouth bar sand facies, tidal flat sandy - silty clay facies, and delta plain silty clay facies. The combined nine sedimentary facies formed sequentially in time, representing the evolution of the sedimentary environment from the Late Pleistocene to the Holocene and the evolutionary process from the continental to the estuarine and Delta environment.
The results also enable the geographic identification and delineation of the incised valley in the Red River Delta during the Late Pleistocene to Holocene period. The sedimentation rate in the incised valley varies from period to period. In the sedimentation phase of the incised valley, the average accretion rate reached 11.64 mm/year. In contrast, during the open sea regime (shallow sea near the coast), the accretion rate was observed to be very low, with a rate of 1.27 mm/year and the period of delta formation had the highest accretion rate, reaching 13.41 mm/year.

Published: June 2023

The article discusses the features of the personal and professional identity of lawyers. A study is being conducted during which two groups of respondents are distinguished, lawyers, as a profession "man-to-man" and clerks.
Research methods. Methodology for the Study of Personal Identity (MILI), author L.B. Schneider. Method L.B. Schneider for determining the level of professional identity. Statistical methods: Fisher's angular transformation — φ. Conclusions. In the course of the study, we found out the following features of the personal and professional identity of lawyers:
1.	The personal identity of lawyers, in contrast to the identity of the respondents in the control group of clerks, is characterized by the following status and age features:
•	the predominance of the status of premature identity in a larger number of lawyers;
•	the achieved personal identity is less typical for lawyers, compared with the respondents of the control group;
•	among younger lawyers, there are more respondents with premature identity and pseudo-identity, however, the achieved identity is less typical for them than for the respondents of the control group.
2.	The professional identity of lawyers, in contrast to the identity of the respondents in the control group, is characterized by the following status and age features:
•	for lawyers, premature identity is most characteristic, however, diffuse and achieved identity are not typical;
•	among young employees, there are fewer respondents with an achieved identity and more often with a premature identity;
•	among mature lawyers, there are more respondents with a diffuse identity.

Background and study species: The endangered oak Quercus brandegeei Goldman, endemic to Baja California Sur, Mexico, is threatened because of its relictual distribution restricted to ephemeral riverbeds, declining populations, and a lack of seedling regeneration. Although there is evidence of viable acorn production, no seedlings or saplings have been found across the range of occurrence for this species.
Hypothesis: We tested for spatial aggregation and factors determining acorn production, hypothesizing that Q. brandegeei trees would be less distant from one another in regions with higher precipitation and that tree attributes and climatic variables would co-determine acorn presence.
Study site and dates: Baja California Sur, Mexico, 2016-2017
Methods: We conducted a Ripley’s K analysis to determine each population’s spatial pattern (random, uniform, clumped) across 12 populations and a total of 194 individuals. To find the impact of environmental factors on acorn production we conducted a series of generalized linear models on eight climatic variables.
Results: Ripley’s K analysis revealed that Q. brandegeei is a highly clumped species, with the highest rate of aggregation occurring within 0-25 meters. Region but not climatic cues were found to be important determinants of presence of acorns.
Conclusions: High aggregation in clumps and low evidence of acorn production in some populations suggests that there is a niche attrition for this species, which is confined to very specific microsites along ephemeral riverbeds. Suitable recruitment areas could be reduced even further under the hotter and drier climate predicted for the region.
