Patients and methods Nine infants aged from 5 to 10 months were diagnosed as prolapsed intussusceptions by clinical examination. All of them were treated by abdominal exploration through a right transverse supraumbilical incision. Results The mean operative time was 65min. The intussusceptum was viable in five cases and was gangrenous in four cases. There was ischemic perforation in the colon in two cases. Resection and anastomosis were performed in six cases, sigmoid colostomy was performed in one case, and reduction by milking without resection was performed in three cases. All the patients recovered well. Conclusion Prolapsed intussusception is a rare presentation of intussusceptions; its diagnosis is easy but may be misdiagnosed as rectal prolapse. Its only treatment is surgery and it carries a good prognosis. Ann Ped...

Based on the differential thermal calorimetry DSC, the as-prepared glasses are heat-treated at 510 ºC for four hours to promote crystallization in the glass network. XRD analysis confirms a formation of CeO 2 and ZnO nanocrystals in the heat-treated glasses with higher CeO 2-content. The degree of crystallization is estimated basing on XRD patterns and density measurements. Optical transmittance spectra of the glasses containing CeO 2 exhibit an approximately zero-transmission in the ultraviolet region and a remarkably high transmission in the visible and infra-red regions, making them dramatically candidates as UV protection sunglasses. The optical band gap is found to decrease with addition of CeO 2 due to formation of more non-bridging oxygens. The activation energy for ionic conduction decreases with increasing CeO 2 content due to the reduction of the concentration of BO 4 units (from FTIR results), which causes a decrease in the cross-linking of the whole glass network. The effect of glass/glass-ceramic transformation on the band gap and activation energy is investigated. It is concluded that the CeO 2-doped glasses are beneficial for the UV blocking, detection of X-ray radiation, and high energy physics. Keywords UV protection sunglasses • CeO 2-doped borate glasses • Electrical and optical properties • Transparent nanoglass-ceramics

In this paper, we present the first FPGA implementation of an approximate tensorial Support Vector Machine (SVM) classifier with algorithmic level ACTs using High-Level Synthesis (HLS). A touch modality classification framework was adopted to validate the effectiveness of the proposed implementation. When compared to exact implementation presented in the state-of-the-art, the proposed implementation achieves a reduction in power consumption by up to 49% with a speedup of 3.2×. Moreover, the hardware resources are reduced by 40% while consuming 82% less energy in classifying an input touch with an accuracy loss less than 5%.

Material and Methods: Ceramic (sapphire) brackets were bonded to 80 extracted human premolars using two enamel etching protocols: conventional EaR using 37% phosphoric acid (PA) gel (control), and a SEP (Transbond Plus). Each group was subdivided into two subgroups (n=20 teeth) according to the time of bracket debonding: after 24 h water storage or following 5000 thermo-cycles plus 5000 cycles fatigue loading, to determine the shear bond strength (SBS), adhesive remnant index (ARI score), with scanning electron microscopy (SEM) evaluation of enamel condition. Results: The control subgroups consistently exhibited significantly higher (p ˂ 0.05) SBS mean values (23.4-29.8 MPa) than the SEP subgroups (15.1-22.4 MPa) at both bracket debonding time points. However, the SEP subgroups yielded milder etch-patterns and attained SBS values above the minimum requirement range for clinical performance. In addition, the higher SBS of control subgroups was accompanied with higher ARI scores and enamel damage grades than SEP subgroups as confirmed by SEM. Thermocycling and fatigue significantly reduced the SBS of all subgroups, with a non-significant drop in the amount of adhesive residue or enamel damage. Conclusions: The use of SEP can be a suitable alternative to the conventional PA gel for sapphire bracket bonding as it maintains suitable bond strength and has the potential to produce both less remnant adhesive and enamel damage.

Aim: To assess the risk factors of SSIs among infants. Subjects and Methods: A descriptive research design was used in the present study to assess the occurrence of SSIs and to detect their risk factors among infants admitted in pediatric surgery unit at Assiut university children hospital and subsequent outpatient clinic and home follow up. Two tools were used, a structured interview sheet to assess socio-demographic data and the possible risk factors for SSIs and observational check list were used to assess the SSIs occurrence. Results: It was found that 15.3% of the operated infants developed SSIs. Infant with history of nutritional diseases or on artificial feeding, infants who didn't take bath before operation and infants who were nursed without hand wash or with the use of unsterile equipments had more SSIs. Conclusion: incidence of SSIs was considered high in infants who had the following risk factors: History of nutritional diseases, infectious diseases, unclean operation, formula feeding, emergency surgery, defect in hand washing and sterilization, using unsterile equipment and antiseptic solution before dressing. Recommendations: The pediatric surgeons and nurses should pay a more perioperative attention to prevent risk factors of SSI among infants.

Materials and methods: A total of seventy one hemodialysis patients, were enrolled in this study. Blood specimens were collected and examined by ELISA technique for the detection of hepatitis B surface antigen (HBsAg) and HCV antibodies (Anti HCV). Results: HBsAg was detected among 9 (12.7%) patients, while 51 (71.8%) patients had HCV infection. Most of patients were males 39 (54.9%), and their age ranged between 14 to 90 with mean age of 42 years. Age, marital status, and the HD center were not statistically significant in HBV and HCV infection. Main risk factors in hemodialysis patients infected by HBV were time duration on HD and vaccination status. Time duration on HD was the most important risk factor in HCV infection. Conclusion: The frequency of HBV and HCV among the studied population is remarkably high. Education about dangerous behaviors along with screening, vaccination, and appropriate treatment for hepatitis is strongly recommended to control this persistent infectious source of hepatitis B and C in the community.

We have a poor understanding of the factors that control SCLC progression and metastasis. TheNFIB transcription factor is frequently amplified in mouse models of SCLC, but clear evidence that NFIB promotes SCLC in vivo is lacking. We report that in mouse models, Nfib amplifications are far more frequent in liver metastases over primary SCLC, suggesting roles in tumor progression/metastasis. Overexpression of Nfib in a sensitized mouse model led to acceleration of SCLC, indicating that Nfib functions as a bona fide oncogene. Suppression of Nfib expression in cell lines derived from the doxycycline-inducible Rb/p53/TET-Nfib model led to increased apoptosis and suppression of proliferation. Transcriptional analysis revealed that Nfib regulates the expression of genes related to axon guidance, focal adhesion and extracellular matrix-receptor interactions. These dat...

Different rates of diammonium phosphate (DAP) were applied to the soil at different depths and it was found that although micro-dosing with DAP increased grain yield over the unfertilized control to a similar level as broadcast DAP, doubling the micro-dosage did not increase it further. Increasing the depth of fertilizer application from 5 to 10 cm resulted in significant increases in root length density, and deep application of fertilizer resulted in higher yields, although the increases were generally not significant. It was postulated that the positive effect of micro-dosing resulted from better exploitation of soil nutrients because of the higher root volume. Levels of nutrients exported from the soil were at least as high in plants receiving micro-dosing as the unfertilized ...

Beit Alpha), seedling vigour, vegetative growth and some biochemical aspects. Salinity stress reduced seeds germination, seedlings fresh mass and seedlings vigour by about 30%, 54%, and 70 % respectively. Moreover, salinity significantly reduced the depletion in seedling dry mass in comparison with control. The magnetic fields of 50 mT for ½ h and 100 mT for 30 s improved seed germination, seedlings fresh mass and seedlings vigour under salinity stress by about 30%, 50% and 150%, respectively in comparison with salinity treatment alone. Conversely, the dual treatment of 200 mT for 1/2 h and salinity stress had more reduction effect on cucumber than salinity alone. In general, the magnetic fields of 50 mT 30 s, 100 mT 1/2 h and 200 mT 30 s had a non significant effect on seed germination. Except for 50 mT 30 s intensity which had a promotive effect, the effect of all used magnetic fields on shoot biomass and chlorophylls content were comparable with those for seedlings fresh mass. The positive effect of magnetic fields seemed to be attributed to the enhancement in total amylase activity, soluble sugars, RNA, K + /Na + ratio and chlorophylls level. On the contrary, magnetic treatments decreased peroxidase activity, total proteins and electrolytes leakage under salinity stress conditions. However, all magnetic intensities increased Fe content, in spite of being independent of magnetic intensity or exposure period.

As an alternative to RPC-based distributed objects, this paper presents Remote Batch Invocation (RBI), language support for explicit client-defined batches. A Remote Batch statement combines remote and local execution: all the remote code is executed in a single round-trip to the server, where all data sent to the server and results from the batch are communicated in bulk. RBI supports remote blocks, iteration and conditionals, and local handling of remote exceptions. RBI is efficient even for fine-grained interfaces, eliminating the need for hand-optimized server interfaces. We demonstrate RBI with an extension to Java, using RMI internally as the transport layer. RBI supports large-granularity, stateless server interactions, characteristic of service-oriented computing.

The aim is to obtain insight into behavior rather than numerical accuracy. The model is quite general and accounts for the fundamental parameters that affect performance, namely network and flow topologies, channel reservation, exponential backoff and hidden nodes. Performances of the most elementary mesh networks (linear, tree, star,...) are analysed using this model. NS simulations are ...
