INFLUENCE OF ANNEALING ON THE STRUCTURAL AND OPTICAL CHARACTERISTICS OF INDIUM OXIDE THIN FILMS PREPARED USING THERMAL EVAPORATION IN A VACUUM METHOD

In the work, the structures and the optical parameters were studied for In2O3 thin films Before and after annealing at different temperatures (400 and 500 ) thin films were prepared on glass substrate by by vacuum thermal evaporation. The X-Ray diffraction showed that In2O3, In2O3 Plasticizedthin films which were prepared to have a polycrystalline cubic structure. The most preferential orientation is along the (321) direction for all deposited In2O3 films. Some parameters of the films were calculated as the average grain size and the dislocation density. Optical properties measurement transmittance (T) of the film shows that they have high transmittance (82.7%) is obtained for at annealing 500 . The optical properties such as absorption coefficient (α) using the transmittance measurement from an UV-vis spectrophotometer, with a range of wavelength (300-1100) nm. And also calculated energy gap for thin films. and also calculated energy gap for thin films, the result has been shown that the optical energy gap increasing with increasing annealing

Acquired air-filled lung cysts in childhood: pathogenesis of cysts of diverse etiologies; nuances of management

Background Air-filled pulmonary parenchymal cysts (pneumatoceles/PCs) – a pathological condition – involving the lung parenchyma may be congenital or acquired. In children, acquired cases are often caused by staphylococcal pneumonias, but other etiologies may also cause PCs and lead to diagnostic confusion.Objectives The aim of this study was to examine the natural history and clinicopathologic features of noncongenital, nonstaphylococcal PCs in children.Patients and methods Four children with nonstaphylococcal PCs were included in this study. A full history, clinical examination, relevant radiological and pathological findings, surgical intervention where relevant, and follow-up were analyzed.Results The cases described represent acquired PCs: one occurred after infarction following cardiac surgery, another was a subpleural pulmonary bleb of inflammatory origin, and the remaining two were post-traumatic pseudocysts. The inflammatory-process bleb and the postinfarction cysts presented with pneumothorax. The postinfarction and post-traumatic PCs responded to observation. The pulmonary bleb was excised.Conclusion Our understanding of the clinicopathologic features and pathogenesis of many types of acquired PCs is incomplete. We propose that PC formation has a basis in destruction of the distal airways of the lung. Damaged tissue may act as a valve, and cause air-trapping, which leads to PC formation. Cysts arising after infarction or after trauma usually resolve on observation. Subpleural blebs may require excision because of nonresolution and recurrence of pneumothorax

Infantile hypertrophic pyloric stenosis: a single institution’s experience

Background/purpose Infantile hypertrophic pyloric stenosis (IHPS) is said to be relatively common in the western world, but its incidence in the Kingdom of Saudi Arabia is unknown. We set out to study the incidence of IHPS in children presenting at our hospital and review the clinical presentation and treatment outcomes of such patients.Patients and methods A retrospective chart review of all cases with IHPS admitted to a tertiary hospital, Riyadh Military Hospital, over 18 years (1990–2008) was conducted. Diagnosis was confirmed by ultrasonography according to the length of the pyloric channel and thickness of the pyloric muscles. An analysis of demographic data, clinical presentation, diagnostic modality, and associated congenital anomalies was carried out. Operative technique, postoperative course, and complication rates were identified.Results The review of the medical records showed 22 patients with a diagnosis of IHPS. The incidence rate of IHPS was 1.4/10 000 live births. Demographically, most cases presented in the first month of life. It is more common in boys. In all, 55% of infants were first borns. Clinically, nonbilious projectile vomiting was the main symptom. Mild dehydration was found in half of the cases with alkalotic changes. Ultrasonography was the main diagnostic modality in 82% of cases. Others were diagnosed by contrast study. Open Ramstedt pyloromyotomy was the surgical approach in 20 (91%) cases and the laparoscopic approach in 2 cases (9%). Fourteen (14%) patients had an associated congenital inguinal hernia. The mean length of hospital stay was 5.5 days. The most common postoperative complication was wound infection in 4.5% of patients. Incidence of IHPS had obvious seasonal association.Conclusion Incidence of IHPS at our hospital (the biggest hospital in the Kingdom of Saudi Arabia with an annual birth record of 14 000) is far less common than international incidences reported in North America and Europe. More reports from Saudi Arabia, the Middle East, and Asia are recommended to support the rarity of IHPS in this region of the world. Seasonal variation suggests a possible etiological role for environmental factors. It is of practical use for both epidemiologists and clinicians for future comparability.Keywords: incidence, infantile pyloric stenosis, risk factor

General characteristics and common practices for ICT projects: Evaluation perspective

In today's business world, organizations are more dependent on Information and Communication Technologies (ICT) resources. Cloud services, communication services and software services are most common resources, enterprises are spending large amount. To install new services and upgrade existing services, ICT project are essential part of organization's business strategies. Researchers highlighted the real problem for the organization is to initiate new ICT projects and its evaluation after implementation. This research investigated the common approaches organizations using to start with ICT projects and how to evaluate its impact on after implementation. For this, we have extracted the number of steps with the help of literature review. To validate those steps, six case studies are selected for collecting the samples. The findings of this study elaborate that every ICT project has list of objectives i.e. strategic, informational, IT infrastructure and others. Furthermore, the results highlight that organizations believe on both financial and non-financial evaluation methods based on the type of organization i.e. public or private. Moreover, measurement process applied on project wise, monthly and yearly bases. Importantly, we have found that currently outsourcing plays significant role in success of ICT projects. The results of this study can be helpful for the organization to understand the type of ICT investments, approaches and possible impact on the organizations goals

Gas Leakage Detection in Recovery Rooms Using a Microcontroller

Gas leakage in medical facilities can pose a serious threat to patient safety and can have catastrophic consequences. Hence, it is essential to detect gas leaks quickly and accurately to prevent any accidents. Various gas detection techniques have been developed to identify gas leaks, including the utilization of Arduino microcontrollers and oxygen sensors. Arduino microcontrollers offer a low-cost and easily deployable solution, while oxygen sensors provide specific detection capabilities for gases commonly used in medical facilities, such as oxygen, nitrogen, and anesthesia gases. Furthermore, the use of advanced technologies such as wireless communication, cloud computing, and artificial intelligence has improved the detection and monitoring of gas leaks.

Manufactured Nano-Objects Confer Viral Protection against Cucurbit Chlorotic Yellows Virus (CCYV) Infecting Nicotiana benthamiana

Nanotechnology has emerged as a new tool to combat phytopathogens in agricultural crops. Cucurbit chlorotic yellows virus (CCYV) mainly infects Solanaceae crops and causes significant crop losses. Nanomaterials (NMs) may have efficacy against plant viruses, but the mechanisms underlying complex nanomaterials-plant-virus interactions remain elusive. We challenged Nicotiana benthamiana plants with GFP-tagged CCYV and observed morphological, physiological, and molecular changes in response to 21-d foliar exposure to nanoscale Fe and Zn and C60 fullerenes at 100 mg/L concentration for 21 days. We observed that in response to C60 (100 mg/L) treatment, plants displayed a normal phenotype while the viral infection was not seen until 5 days post-inoculation. On the contrary, Fe and Zn were unable to suppress viral progression. The mRNA transcriptional analysis for GFP and viral coat protein revealed that the transcripts of both genes were 5-fold reduced in response to C60 treatment. Evaluation of the chloroplast ultrastructure showed that NMs treatment maintained the normal chloroplast structure in the plants as compared to untreated plants. C60 upregulated the defense-related phytohormones (abscisic acid and salicylic acid) by 42–43%. Our results demonstrate the protective function of carbon-based NMs, with suppression of CCYV symptoms via inhibition of viral replication and systemic movement
