The study showed the repellent effect of three types of plant powders, Mentha, Myrtus and Ocimum basilica, against rice weevil Sitophilus oryzae (L.) (Coleoptera: Curculionidae), the results of the study showed that the Myrtus powder had the highest rate of repellent to insects. It reached the highest percentage of repellent outside the loop within 24 hours 41% at concentration of 6% where it was found that there was a significant difference in percentage compared to other plant powders (Mentha, Ocimum basilica) reached 39.5% and 37.5 %, respectively.

The majority of studies' interests change grave not harmful state of being gathered or focused components "in the hair" of kids with neurodevelopmental disorders like ASD. A survey of field medicine describes demonstrated mercury exposure, whether organic, or inorganic can result in the development of characteristics symptoms that characterize or are frequently observed in autism spectrum disorders (ASD). The (DSM-IV) diagnostic criteria of autism include deficits with interpersonal relationships, having trouble expressing oneself, and engaging in behaviors that are both stereotypical and repetitious , all of which be brought on by mercury.

In this paper, the chaos synchronization of four Nano quantum cascade lasers with optoelectronic feedback was investigated. The present system consists of two receiver lasers and two transmitters lasers. The rate equation model was modulated to study the effect of the Purcell factor F and the spontaneous emission factor because of their importance in a nanocavity. The results indicated that the suggested system, realize the chaos synchronization. Also, the nanocavity parameters F and β, have significant effect on the chaos synchronization quality and may lead to lose it. Furthermore, the results showed the weak effect of delay time on the performance of lasers.

Urinary tract infections (UTIs) in women are one of the most common diseases affecting at different ages of the life. This study was aimed to investigate the uropathogenes in women with UTI and to test their antibiotic susceptibility pattern. A total of 150 urine samples were collected from patients women and healthy in Thi-Qar Province, southern Iraq, between December 2022 and March 2023.Urine samples were collected from each participant women and cultured on media, then identified by different laboratory methods such as characteristic of colony on culture media, Gram stain, biochemical tests and morphologic chromatic properties on Hi UTI chromogenic agar and confirmed by API 20E system. The majority of females (44%) were the age groups 25 to 34 years followed by the (34%) patients were age group from 15 to 24 years. Antibiotic susceptibility testing for bacteria species was performed using the Kirby,Bauer disc, diffusion technique. Out of 136 different isolates with noticeable growth were found in the urine sample after microbiological cultures were performed, bacteria species was represented (63.24%) more than Candida species which was (36.76%). The most frequent bacterium was Staphylococcus species (40.69%) followed by Escherichia coli (18.60%). These bacterial exhibited extremely resistance to antibiotics. Gram positive isolates showed the highest resistant against Amoxicillin-clavulanate (100%), Ampicillin (100%), Oxacillin (100%), and Trimethoprim (91.66%), on the other hand Gram negative bacteria also showed the highest resistance against Amoxicillin-clavulanate (100%), Piperacillin (100 %), and both Ceftazidime and Nitrofurantoin (86.36 %). Other antibiotics showed different results by different bacterial species.

An uncommon autosomal recessive condition called DREAM-PL syndrome is typified by dysmorphic facial features, renal agenesis, male ambiguous genitalia, microcephaly, polydactyly, and lissencephaly. The CTU2 gene, which is in charge of tRNA post-transcriptional modification, is mutated in the syndrome. This alteration is necessary for the correct translation of genes, and its disruption can result in several aberrant embryonic processes. The severity of DREAM-PL syndrome can vary from moderate to severe, and the clinical characteristics can be diverse. While some patients may exhibit only some of the distinguishing features, others may have all of them. The most common characteristics include ambiguous genitalia, dysmorphic facies, and microcephaly. Diagnosis of DREAM-PL syndrome is typically based on clinical signs and confirmed through genetic testing, which can identify mutations in the CTU2 gene. Material and methodology: In the case being referred to as a study, a 37-week-old male neonate was delivered by lower segment cesarean section. The baby's birth weight was 2.760 Kg, and a heterozygous CMP mutation of the CTU2 gene was confirmed through whole-exome sequencing (WES). Unfortunately, there is currently no known cure for DREAM-PL syndrome. Result: Treatment focuses on managing the symptoms and providing supportive care. In some cases, surgical correction of birth defects may be beneficial.

A decorated ferrimagnetic mixed triangular system was studied using the molecular mean-field approximation. The outcomes of the investigation were examined using the Blume-Capel Ising model. The study paper investigates the influence of crystal and external magnetic fields on ferrimagnetic devices decorated with mixed spin-2 and spin-7/2 of a triangular lattice. It is noteworthy that spin-2 ions are located at the nodal points, whereas six additional spin-7/2 ions surround the proposed lattice. Altering the exchange interactions through the specific crystal and external magnetic fields induces superparamagnetic behaviours. New characteristics reveal that mixed spin triangular decorated ferrimagnets exhibit superparamagnetic behaviour at DA∕|J2|=-2.5, with J1 = -0.5 and J2 = -1.0 in the range (15 ≤ KBT /|J2| ≤ 18). It is important to note that the total magnetization changes with the external magnetic field and affects the superparamagnetism phenomenon of a decorated mixed spin ferrimagnet when DA/|J2| = 8, and DB/|J2|=-11, J1 = -0.5 and J2 = 1, for KBT/|J2| = 2, 2.5, 3, 3.5, and 4 Ko respectively.

In This study, we modified the Anderson-Newns model for atomic chemisorption to be suitable for the chemisorption of a spherical semiconducting quantum-dot on a monolayer pure perfect graphene. A mathematical expression was used to calculate the occupation numbers for the two levels of the quantum-dot as a function of the normal distance and the external electric field. Appropriate formulas for other chemisorption functions were used by taking into our account the effect of image shift, and a formula for hybridization energy as a function of distance only. The quantum-dot was considered a spherical shape, chooses the type of on-top adsorption on the graphene layer, also taken a fixed value for the correlation energy U to be spin independent and not dependent on distance. At room temperature T=300 K, the occupation numbers and their corresponding energy levels were calculated by stabilizing all the parameters and varying the strength of electric field individually by both positive and negative directions. The contribution of the negative electric field was more effective on quantum-dot chemisorbed on graphene.
在这项研究中，我们修改了原子化学吸附的安德森-纽恩斯模型，使其适用于球形半导体量子点在单层纯净完美石墨烯上的化学吸附。我们使用数学表达式计算了量子点两个水平的占位数与法向距离和外部电场的函数关系。考虑到图像偏移的影响，我们使用了其他化学吸附函数的适当公式，以及仅作为距离函数的杂化能公式。量子点被认为是球形的，选择了石墨烯层上的顶部吸附类型，还为相关能 U 取了一个固定值，使其与自旋无关且不依赖于距离。在室温 T=300 K 时，通过稳定所有参数并通过正负两个方向单独改变电场强度，计算了占据数及其相应的能级。负电场对石墨烯上的量子点化学吸附更有效。

Patients from the Specialized Heart Center in Thi-Qar Governorate with various diseases. A number of fungal species, including Candida tropicalis, were isolated by two samples from this isolate. Yeasts were purified and their DNA was extracted and then the DNA was transferred for the purpose of sending it to the Korean company in order to identify genetic mutations. For these species, a number of important genetic mutations were identified and recorded in the Gen Bank, as these isolated species contained genetic mutations that were compared with species isolated in other countries of the world that were officially registered in the Gen Bank. These fungi are considered the most important types of yeasts. They belong to the genus Candida and create a range of health problems for most people due to the fungal toxins they carry or the significant lung pathologies they cause. They can also be lethal or cause a number of serious ailments in most individuals.
来自济加尔省心脏专科中心的各种疾病患者。从该分离物的两个样本中分离出包括热带念珠菌在内的多种真菌。对酵母进行纯化，提取其 DNA，然后将 DNA 转移到韩国公司，以确定基因突变。这些分离出来的菌种与在世界其他国家分离出来并在基因库中正式登记的菌种相比，含有更多的基因突变，因此在基因库中发现并记录了一些重要的基因突变。这些真菌被认为是最重要的酵母菌类型。它们属于念珠菌属，由于携带真菌毒素或导致严重的肺部病变，给大多数人带来一系列健康问题。它们还可能致命，或对大多数人造成一系列严重疾病。
