Published: September 2024

Abstract
Traditional single-fiber spectroscopy provides a single galaxy spectrum, forming the basis for crucial parameter estimation. However, its accuracy can be compromised by various sources of contamination, such as the prominent Hα emission line originating from both star-forming (SF) regions and non-star-forming (NonSF) regions, including active galactic nuclei. The potential to dissect a spectrum into its SF and NonSF constituents holds the promise of significantly enhancing precision in parameter estimates. In contrast, integral field unit (IFU) surveys present a solution to minimize contamination. These surveys examine spatially localized regions within galaxies, reducing the impact of mixed sources. Although an IFU survey’s resulting spectrum covers a smaller region of a galaxy than single-fiber spectroscopy, it can still encompass a blend of heterogeneous sources. Our study introduces an innovative model informed by insights from the Mapping Nearby Galaxies at Apache Point Observatory IFU survey. This model enables the decomposition of galaxy spectra, including those from the Sloan Digital Sky Survey, into SF and NonSF components. Applying our model to these survey data sets produces two distinct spectra, one for SF and another for NonSF components, while conserving flux across wavelength bins. When these decomposed spectra are visualized on a Baldwin, Phillips, and Terlevich (BPT) diagram, interesting patterns emerge. There is a significant shift in the placement of the NonSF decomposed spectra, as well as the emergence of two distinct clusters in the Low-ionization Nuclear Emission-line Region and the Seyfert region. This shift highlights the key role of SF “contamination” in influencing the positioning of NonSF spectra within the BPT diagram.
Revised Reaction Rate for the Astrophysical Reaction 18O(p, α)15N via a Global R-matrix Analysis
Authors: Li Yi-Yang , Hu Jun , Ru Long-Hui , Tian Ning , Lv Jin-Feng 
Published: September 2024

Abstract
The 18O(p, α)15N reaction is of particular importance for influencing the abundances of key isotopes such as 19F, 18O, and 15N. Peculiar abundances for these nuclei are observed from spectra or meteorite grains originating in asymptotic giant branch stars. The 18O(p, α)15N could provide a way to explain the discrepancy between the observations and model predictions. A comprehensive R-matrix analysis has been performed for the 18O(p, α)15N reaction by including additional constraints from other reaction channels; in particular, the 15N+α scattering data were involved in the analysis for the first time. All available data were compiled and used in the R-matrix analysis. The fitted resonance parameters are compared with previous works. A revised determination of reaction rate has been extracted, relying on the present fitting parameters. The uncertainties on the corresponding reaction rates were then obtained by a Monte Carlo analysis.

Published: September 2024

Abstract

Background:
Techniques for identifying facial features and proving the individuality of a person’s facial features are used in forensic anthropology.

Aims and Objectives:
A common method in this area is cranial anthropometry, which has uses in facial reconstruction, locating unidentified remains, and identifying criminal suspects.

Materials and Methods:
A study analyzed 200 standard full-face photographs of 50 males and 50 females to compare frontal and lateral facial images and identify male and female facial traits. We located landmarks and measured the distances between them. The data were analyzed using statistical tests like t-tests and analysis of variance (ANOVA) tests.

Result:
The results showed that in 100% of the suggested measurements for both males and females, there were no statistically significant differences (P > 0.05) between frontal and lateral views. The ANOVA test, however, showed that all suggested measurements showed differences in the lateral aspect, while only 76.92% of them showed differences between the male and female groups in the frontal aspect.

Conclusion:
In conclusion, statistically significant differences were found, rejecting the null hypothesis of equal means, when the level of significance (α) was lower than the P value (0.05). On the other hand, the null hypothesis was accepted when statistically insignificant differences were found and the level of significance was higher than the P value. Although there were differences between males and females in different views, the distances between landmarks in frontal and lateral views of the same person were generally similar. Measurements taken in the lateral aspect were more accurate and displayed greater sexual dimorphism variation compared to those taken in the frontal aspect.
Geoforensic Methods for Detecting Clandestine Graves and Buried Forensic Objects in Criminal Investigations – A Review
Authors: Narreddy Vaishnavi 
Published: September 2024

Abstract
Geoforensic techniques are being deployed in searches for hidden objects to counteract the shortcomings of conventional blunderbuss methods. Processing of crime scenes during searches for clandestine graves and buried objects is often destructive. Manual excavation and other invasive methods are restricted in many contemporary situations, and the location of a body is essential for forensic investigations. Geoforensics and geophysical surveys are important tools for assisting law enforcement agencies in locating crime scenes, clandestine graves, drugs, artifacts, hazardous waste, and illegal weapons and ammunitions stored underground in preparation for terrorist attacks. Geoscience search techniques such as the geoforensic search strategy are among many models used to help find mass graves, locate missing persons, and verify information acquired from incomplete intelligence. Trace amounts of soils, sediments, and other geological materials can provide geolocations and aid in the development of a primary search area. Forensic geoscience techniques and equipment such as metal detectors, magnetic surveys, electromagnetic conductivity surveys, ground penetrating radar surveys, augering (probing), detector dogs surveys, and gravity and seismic fluctuation monitoring are discussed in this paper. In addition to the location of potential graves and ambush sites, the soil beneath the decomposing cadavers can be used to predict the postmortem interval for the deceased. Soil information and geo-mapping data can provide productive intelligence for military and national security agencies. Antiquities crimes and crimes involving gemstones in which the evidence passes through many hands can be traced back to the place of origin by checking for their geo-morphology. Serious crimes, including murder, genocide, and terrorism, can be prevented by the use of operational and decisive geoforensic techniques. This paper highlights the multidisciplinary information exchange that occurs between forensic burial science, forensic geology, and trace evidence in criminal investigations. The paper also focuses on geoforensic approaches to clandestine grave searching, underwater investigations, forensic engineering fallacies, military intelligence, ambush detection, and weapons mining.

Published: September 2024

Abstract

Background:
Bite mark identification is based on the individuality of a dentition and helps in identifying the perpetrator. The use of three-dimensional (3D) analysis of forensic evidence is highlighted in comparison with traditional methods. CBCT has been used in registering bite mark on food material. To our knowledge this is the first study where CBCT is used to register bite mark from human forearm.

Aims and Objective:
To signify the potential of CBCT in registering and analysing the bite mark on human skin and to analyse various identifying parameters.

Materials and Method:
60 subjects of either sex were asked to bite their own forearm and alginate impression of the maxillary and mandible dentition was taken and cast was poured. Both bitemark and cast was subjected to CBCT scanning and parameters like arch shape, inter canine width, mesio distal dimension of anterior teeth, and individual characteristics like rotation, buccal/lingual tilting of teeth was noted and compared and assigned a score using simplified version of ABFO scoring system.

Results:
Highly significant result with 56.6% definite match, 26.66% probable match and 16.66% possible match were obtained using CBCT.

Conclusion:
CBCT is a non-destructive, accurate, efficient, objective and reproducible method. Out of all parameter mesio-distal dimension of teeth is the best parameter to judge the bitemark on skin.

Published: September 2024

Background and Purpose:
Size-specific dose estimates (SSDE) have been introduced into computed tomography (CT) dosimetry to tailor patients’ unique sizes to facilitate accurate CT radiation dose quantification and optimization. The purpose of this study was to develop and validate an automated algorithm for the determination of patient size (effective diameter) and SSDE.

Materials and Methods:
A MATLAB platform was used to develop software of algorithms based on image segmentation techniques to automate the calculation of patient size and SSDE. The algorithm was used to automatically estimate the individual size and SSDE of four CT dose index phantoms and 80 CT images of pediatric patients comprising head, thorax, and abdomen scans. For validation, the American Association of Physicists in Medicine (AAPM) manual methods were used to determine the patient’s size and SSDE for the same subjects. The accuracy of the proposed algorithm in size and SSDE calculation was evaluated for agreement with the AAPM’s estimations (manual) using Bland–Altman’s agreement and Pearson’s correlation coefficient. The normalized error, system bias, and limits of agreement (LOA) between methods were derived.

Results:
The results demonstrated good agreement and accuracy between the automated and AAPM’s patient size estimations with an error rate of 1.9% and 0.27% on the patient and phantoms study, respectively. A 1% percentage difference was found between the automated and manual (AAPM) SSDE estimates. A strong degree of correlation was seen with a narrow LOA between methods for clinical study (r > 0.9771) and phantom study (r > 0.9999).

Conclusion:
The proposed automated algorithm provides an accurate estimation of patient size and SSDE with negligible error after validation.

Many applications of green synthesis in the field of environment and biomedicine aiming at decreasing the use of toxic chemicals through utilizing of plants which are safe. In this study, at 0.1 M concentration of copper sulfate (CuSO4.5H2O), CuNPs were prepared and identified by changing the blue color into green color (ethanolic extract) and from blue color to black color (water extract) and the spectrophotometric detection of ultraviolet and infrared spectra. X-Ray diffraction (XRD) pattern was utilized to confirm the crystal structure of CuNPs. The morphology and size of the CuNPs was measured by a high-resolution transmission electron microscope (HR-TEM). Energy dispersive X-ray (EDX) was used for identification of the elemental composition of CuNPs involving copper and oxygen. Field emission scanning electron microscopy (FESEM) was utilized to confirm the shape of prepared copper nanoparticles. In vitro antibacterial activity was tested using two methods including desk diffusion assay considering zones of inhibition and minimum inhibitory concentration (MIC) against six types of certain bacterial types (Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, Staphylococcus aureus, Streptococcus pneumoniae and Enterococcus faecalis). The results showed potent inhibitory activity of copper nanoparticles (CuNPs) and water extract (Ext. 2) against all bacterial strains.

Trizma base is a small organic compound that possesses one amino group (-NH2) and three hydroxyl groups (-OH). Three products of trizma base as a ligand were prepared from the reaction of Mg(II), Ca(II), and Ba(II) ions with the ligand at a temperature of 65 °C and stoichiometry of 1:1 (ligand to metal ion). The trizma ligand was referred to as Tris, and its complexes with Mg(II), Ca(II), and Ba(II) ions were referred to as Product 1, Product 2, and Product 3, respectively. After the preparation of the products, they were characterized by several analytical methods, including spectroscopies [Fourier-transform infrared (FT-IR) and ultraviolet/visible (UV-visible)], thermogravimetry (TG), elemental analyses, X-ray diffraction (XRD), and scanning electron microscope with environmental mode (ESEM). Analytical results suggested that Tris ligand captured the investigated metal ions using the amino group (-NH2) and one hydroxyl group (-OH) forming complexes with general composition of [MgTris(H2O)4]·Cl2·2H2O (Product 1), [CaTris(H2O)4]·Cl2·2H2O (Product 2), [BaTris(H2O)4]·Cl2·H2O (Product 3). The corresponding gross formulas for these products were C4H23NO9MgCl2 (324.34), C4H23NO9CaCl2 (340.11), and C4H21NO8BaCl2 (419.37 g/mol), respectively. SEM micrographs captured at high levels of magnification (×100,000) clearly illustrate variations in the morphology of products 1, 2, and 3.
