The current research uses density functional theory (DFT) approximations in conjunction with the plane wave-pseudopotential method to investigate structural, electronic, and optical properties of Pb-free cubic perovskite RbGeX 3 (X= I, Br and Cl) materials. More specifically, Norm-conserving pseudopotential has been employed to describe the ion and valence electrons interaction, and GGA-PBE flavor is used to represent the exchange-correlation part of the energy of the GGA approximation. Lattice parameters obtained are 5.95, 5.55, and 5.29 Å for RbGeX 3 (where X=I, Br, and Cl), respectively, and they are comparable with available empirical and other values. The direct band gap nature of the three compounds under research here is shown and our values of the band gap energy 𝐸 𝑔 are agree with the other available results. Materials under research show responses to electromagnetic radiation starting from the infrared region to very high energies ( ~ 33 eV). The RbGeI 3 has the lowest 𝐸 𝑔 value at the low region energies and the highest optical response peaks but RbGeCl 3 has the highest optical response peaks at energies located near ~ 20 eV. Our results show that these materials are good candidates for photo electronic applications including solar cells

At the confluence of food science and animal science, using dietary techniques to improve the quality of meat may be a cutting-edge strategy. In this experiment, 200 chickens were separated into 20 cages, with each cage covering 10 chickens. Six chickens were chosen randomly to evaluate research parameters, and the findings were applied to a CRD (completely randomized design), which included five treatment groups and four replications. The effects of dietary (T1) control without Supplementation (T2) garlic powder, (T4) hot red pepper, (T3) dark pepper, and (T5) a mixture of them on the qualitative characteristics of chicken thigh and breast meat were assessed. Meat's chemical characteristics and quality assessments included assessments of the meat's quality (PH, moisture, protein, fat, and ash). Plant supplementations exhibited a significant (P≤0.05) impact on most of the evaluated chicken meat quality criteria, with black pepper being the exception. In conclusion, plant supplementations had a favorable impact on the quality of chicken meat.

Fritillaria species belongs to Liliaceae family, it has been used as medicinal plants in traditional Chinese medicine for more than 2000 years. These plants are known with significant variations in their chemical profiles. Consequently, the characterization of the profile of the major bioactive constituents in various regions are important for pharmaceutical purposes. Despite the identification of numerous species of Fritillaria in Kurdistan, there is no previous study examining phytochemical components of Fritillaria in this region. This study aims to investigate the distribution of major bioactive compounds in wild bulbs of Fritillaria spp. in Kurdistan. 40 compounds were totally detected using Gas Chromatography-Mass Spectrometry (GC-MS). Among the detected compounds, 15 of them were previously found to have effective biological activities. Results have also shown that amongst the underlying Fritillaria species, variations of the types and quantities of the 15 bioactive compounds were significant. This result is of importance for the classification of different Fritillaria. spp. with distinct geographic distributions and medicinal applications.

Calcium carbonate, lime, is a major component of the regolith, especially in arid and semi-arid regions. Lime affects soil characteristics, is a substantial store of earthly carbon, and is used in mineral investigation. Total lime is functioning component in the cultivation of Calcium carbonate and it is formed when calcium ions in hard water interact with carbonate ions to make limescale. Remote Sensing (RS) data and techniques integrated with Geographical Information System (GIS) play an important and prominent role in studying soil properties and how they are distributed by introducing the proportions and concentrations of chemical elements in the soil into GIS programs and then mapping the density of these elements and linking them spatially to the study area, and thus the spatial analysis of these elements. The study aims to map the distribution of the lime-rich regions utilizing remote sensing and geographical information system data and techniques integrated with field data observations in the Garmian region, Sulaimaniyah Province, Kurdistan Region, Iraq. Total of 80 well-distributed samples were tested precisely in the laboratory. Twelve samples were used as training samples in the classification, and the rest were used for checking the accuracy of the produced maps. The results also showed that Maximum likelihood classification is a reliable method that can be used on Landsat images to extract viable information on lime-rich regions and can predict the attendance and distribution of the lime-rich regions. It is clear that the amounts of calcium carbonate increase towards the study area south because the parent material is limestone and sandstone, which are rich in calcium carbonate, and also because of the low rates of rainfall in that area, which is not sufficient to dissolve the lime and wash it from the soil section.

Bacterial endophytes are host-beneficial microbial symbionts inhabiting different plant tissues without causing damage to the host plant. To our knowledge, no previous data was available regarding the endophytic bacterial population colonizing root nodules of plant legumes in this region. Therefore, this study was conducted to identify and assess the biodiversity of the bacterial endophytes of four different legumes species of the Fabaceae family, including Chickpea, Faba bean, Common bean, and Lentil in Duhok province, using 16S rDNA sequencing. The results revealed that 69 different pure culture colonies were isolated based on the phenotypic characteristics of endophytes on YEM medium and Gram staining. Based on 16S rDNA sequencing, seventeen bacterial species have been identified, with the sequence identities ranging from 98.41-100%. They belonged to nine different bacterial genera. The identified bacterial genera were Pantoea sp. (35%), Enterobacter sp. (26%), Clostridium sp. (15%), Kosakonia sp. (9%), Pseudomonas sp. (4%), Curtobacterium sp. (4%), Erwinia sp. (3%), Salmonella sp. (3%), and Rahnella sp. (1%). These bacterial genera belonged to four Phyla, including Pseudomonadota , Bacillota , Proteobacteria , and Actinobacteria . The antibacterial sensitivity against six various antibiotics by disc diffusion method showed different resistant patterns (bacitracin 78%, amoxicillin 56%, rifampin 34%, erythromycin 11%, chloramphenicol and tetracycline 6%), respectively. The phylogenetic analysis clustered the identified bacterial endophytes into three major clades and 11 different sub-clusters (C1 to C11), with a high degree of similarity amongst bacteria belonging to the same species. In conclusion, the population densities, species richness, and frequency of isolated endophytes showed variations based on geographical locations and the type of plant legumes. Finally, the results of the current investigation might add significant knowledge regarding endophytic bacterial populations colonizing different plant legumes in this region

Corn or Maize product is regarded as one of the essential products in the world and stands third product after the rice and wheat crops. Different fungal pathogens attack corn plants; one of them is ear rot, brought on by Fusarium species and whose occurrence is primarily influenced by environmental factors. In order to isolate and identify Fusarium species from corn plants and their prevalence, 50 samples of corn were collected during September, October, and November of 2021 from 30 corn fields in 14 regions of different places in the Kurdistan region of Iraq. From all samples, 39 isolates of Fusarium were detected and based on morphological characteristics, six other species of Fusarium were identified, namely F. verticillioides (33.34%), F. proliferatum (25.64%), F. oxysporum (12.82%), F. incarnatum and F. equiseti (10.25% each), then F. fujikuroi (7.7%). The most prevalent species was F. verticillioides which was isolated from seven corn fields and significantly higher than all other isolated species. All Fusarium isolates were also molecularly identified depending on amplifying the internal transcribed spacer (ITS) universal region using forward ITS1 and reverse ITS4 primers and indicated DNA fragments ranged from 550 to 570 bp. The PCR fragments of the amplified ITS region were sequenced, aligned and registered in NCBI GeneBank with specified accession numbers. The phylogenetic tree and all analyzes were performed using the MEGA program version 11.0.13. The current study concluded that the corn fields in the Kurdistan region are infected with different Fusarium species, and the most common species is F. verticillioides . As well as the Fusarium species in the Kurdistan region have close evolutionary history to the same species in other countries. Thus, the study recommends more research to investigate the occurrence of toxigenic Fusarium species associated with cereal grains in the region.

The attractive interactions between Boron, B, and Nitrogen, N, codoped atoms in graphene nanosheets are calculated based on Density Functional Theory, DFT, using Quantum Espresso software, QE. We realized that the electron density distribution is strongly localized along B-N bonds when there is a strong attractive force between the dopant’s atoms; however, when there is a lesser attractive force, the electrons are delocalized over the B-N bond of the hexagonal graphene ring. The molecular dynamic simulation is done to determine the thermal stability of the nanosheets. Additionally, since graphene is made up of a hexagonal structure, the locations of B or N atoms in para-, meta-, and ortho-positions are more sensitive. Furthermore, the symmetry of spin up and spin down of the band structure show that these monolayers are nonmagnetic materials. Moreover, we employed Phonopy software to demonstrate the specific heat capacity of the monolayers from 0 K to 1000 K, which is in the high-temperature limit. Based on our estimations, the BN-codoped graphene monolayers are beneficial in thermoelectric and optoelectronic devices.
