Drop call is an example of a problem that is often experienced by users of voice telecommunications services. From this condition, this riset raises the topic of drop call analysis on WCDMA networks in the Renon cluster (nodeB MYAMIN_CR, AKABA_PL, and BUNDARANRENON_PL). Data retrieval needed (Call Set Up Success Rate (CSSR), Call Drop Ratio (CDR), RSCP and Ec/No) is done by drive test using G-NetTrack Pro software. Based on the analysis of the results of the drive test, there were 10 drop call problems. The problems indentified cause by missing neighbors, handover failure, bad spot, coverage problems and overshoot. Bad spots, coverage problems, and overshoot are the initial causes of missing neighbors and handovers failure. Missing neighbors and handover failure begins with the poor value of RSCP and Ec/No, so that the cellphone will try to do a handover. To analyze the drive test results, drive test data is carried out using Atoll software. From the comparison found extreme conditions resulting from obstacle which cause a significant difference in value between the results of the drive test and simulation. The high attenuation rate drop call location due to the obstacle also results in RSCP and Ec/No values being obtained when measurements in the field are low. The low parameter values of RSCP and Ec / No then cause a drop call.

Oedometer Tests

The paper describes the results of oedometer tests carried out with samples from Eemian fresh-water deposits and the methods used to determine the preconsolidation pressure from the test results. The influence of creep in the material on the apparent preconsolidation pressure is estimated from a model set up by Moust Jacobsen in 1992. The test results do not show any significant difference in the determined values of the overconsolidation ratio (OCR) for the samples from Hollerup and SolsØ, east and west of the main stationary line for the last ice sheet in Weichselian, respectively. The results, however, te11 nothing about the kind of actions, which has caused the overconsolidation. The determined OCR-values might be due to previous ice caps but a big difference in the two values from Solso indicates a considerable influence from other actions. The sediments from Hollerup and SolsØ are not identical, and the effect of temperature, chemical and biological processes on the apparent preconsolidation pressure has not been evaluated.

We examined 35 early, 32 mid-season and 12 mid-late winter wheat varieties on calciferous chernozem soil after sunflower green crop in 2003. We set-up the experiment on small-size parcels, with 4 repetitions. In addition to the favourable agrotechnical conditions, with this year’s extreme ecological conditions the varieties resulted in weaker yields (2500-3200 kg/ha). Our findings have proven that there is a significant difference both between the maturity groups and between the yield potential of varieties with different genotypes, inside each group. Early varieties showed lower yield potentials according to the other two groups. The differences between the various variety’s yields was the smallest in the mid late group (893 kg/ha). Under given ecological and agrotechnical conditions, the following varieties showed the relatively best yields and best adaptability:• early maturing varieties (3200-3700 kg/ha): Mv palotás, KG Magor, Mv Mambo, Mv Emese, GK Margit, GK Tündér, GK Csongrád, GK Attila, Mv Amanda, Ukrainka;• mid season varieties (3300-3800 kg/ha): Győző, GK Marcal, Róna, GK Rába, Buzogány, MF Kazal, GK Mura, Hunor, GK Cipó, Mv Magvas, Mv Vilma, GK Zugoly, Jubilejnaja 50;• mid-late varieties (3200-3600 kg/ha): Maximus, Complet, KG Kunhalom, GK Holló.

The One of many way to connect to the database through the android application is using volleyball and RESTAPI. By using RestAPI, the android application does not directly connect to the database but there is an intermediary in the form of an API. In android development, Android-volley has the disadvantage of making requests from large and large data, so an evaluation is needed to test the capabilities of the Android volley. This research was conducted to test android-volley to retrieve data through RESTAPI presented in the form of an application to retrieve medicinal plant data. From the test results can be used by volley an error occurs when the back button is pressed, in this case another process is carried out if the previous volley has not been loaded. This error occurred on several android versions such as lollipops and marshmallows also on some brands of devices. So that in using android-volley developer need to check the request queue process that is carried out by the user, if the data retrieval process by volley has not been completed, it is necessary to stop the process to download data using volley so that there is no Android Not Responding (ANR) error.Keywords: Android, Volley, WP REST API, ANR Error

Background: The condylar position discrepancy between centric relation and maximal intercuspation has been still a controversial issue. Aims: To compare the condylar position between centric relation and maximal intercuspation using cone-beam tomography in patients without temporomandibular joints disorder. Materials and methods: To assess the condylar position in centric relation and maximal intercuspation using cone-beam tomography on 40 fifth-year and sixth-year dental students of Hue University of Medicine and Pharmacy without temporomandibular joints disorder. The condylar positions are assessed following Sener classification (2009) and are compared between centric relation and maximal intercuspation using pairedsamples t-test and Mann-Whitney U-test. Results: Among 480 condye-to-fossa measurement pairs, there are 91.2% pairs having difference between two reference position but there is no significant difference. The condylar position at the superior of mandibular fossa has the greatest percentage in both centric relation and maximal intercuspation (43.8% in centric relation and 51.2% in maximal intercuspation). This greatest percentage is followed by the condylar position at posterior of mandibular fossa (32.5% in centric relation and 36.3% in maximal intercuspation). Lastly, the condylar position at the anterior of mandibular fossa has the fewest percentage (23.7% in centric relation and 12.5% in maximal intercuspation). Conclusion: There is no significant difference of condylar position between centric relation and maximal intercuspation in patients without temporomandibular joints disorder. Key words: Condylar position, centric relation, maximal intercuspation, cone-beam tomography

PurposeTo assess whether pars plana vitrectomy (PPV) is an aerosol-generating procedure (AGP) in an ex vivo experimental model.MethodsIn this ex vivo study on 10 porcine eyes, optical particle counter was used to measure particles ≤10 μm using cumulative mode in the six in-built channels: 0.3 μm, 0.5 μm, 1 μm, 2.5 μm, 5 μm and 10 μm aerosols during PPV. Two parts of the study were as follows: (1) to assess the pre-experimental baseline aerosol count in the theatre environment where there are dynamic changes in temperature and humidity and (2) to measure aerosol generation with 23-gauge and 25-gauge set-up. For each porcine eye, five measurements were taken for each consecutive step in the experiment including pre-PPV, during PPV, fluid–air exchange (FAX) and venting using a flute with 23-gauge set-up and a chimney with 25-gauge set-up. Therefore, a total of 200 measurements were recorded.ResultsWith 23-gauge and 25-gauge PPV, there was no significant difference in aerosol generation in all six channels comparing pre-PPV versus PPV or pre-PPV versus FAX. Venting using flute with 23-gauge PPV showed significant reduction of aerosol ≤1 μm. Air venting using chimney with 25-gauge set-up showed no significant difference in aerosol of ≤1 μm. For cumulative aerosol counts of all particles measuring ≤5 μm, compared with pre-PPV, PPV or FAX, flute venting in 23-gauge set-up showed significant reduction unlike the same comparison for chimney venting in 25-gauge set-up.ConclusionPPV and its associate steps do not generate aerosols ≤10 μm with 23-gauge and 25-gauge set-ups.

Abstract Objective External dacryocystorhinostomy is thought to cause mucociliary dysfunction by damaging the mucosa, in turn affecting ciliary activity and mucus quality. This study investigated the effect of external dacryocystorhinostomy on sinonasal function. Methods Patients scheduled for unilateral external dacryocystorhinostomy who underwent endoscopic nasal examination and paranasal sinus computed tomography were included in this study. A saccharine test was performed on the planned surgical side and the mucociliary clearance time was determined. The sinonasal quality of life was measured in all patients, pre-operatively and at six months post-operatively, using the Sino-Nasal Outcome Test-22. The Lund–Kennedy endoscopic score was also determined in all patients, both pre- and post-operatively. Results The study comprised 28 patients (22 females and 6 males). A statistically significant difference was found between the pre- and post-operative saccharine test results (p = 0.006), but not between the pre- and post-operative Sino-Nasal Outcome Test-22 scores (p > 0.05). Conclusion This study is one of only a few to investigate the effect of external dacryocystorhinostomy on sinonasal function. The results showed that external dacryocystorhinostomy impairs mucociliary clearance. The surgical procedure is well tolerated and does not significantly change nasal symptom scores.

AbstractClassification of Aedes aegypti (Linnaeus) and Aedes albopictus (Skuse) by humans remains challenging. We proposed a highly accessible method to develop a deep learning (DL) model and implement the model for mosquito image classification by using hardware that could regulate the development process. In particular, we constructed a dataset with 4120 images of Aedes mosquitoes that were older than 12 days old and had common morphological features that disappeared, and we illustrated how to set up supervised deep convolutional neural networks (DCNNs) with hyperparameter adjustment. The model application was first conducted by deploying the model externally in real time on three different generations of mosquitoes, and the accuracy was compared with human expert performance. Our results showed that both the learning rate and epochs significantly affected the accuracy, and the best-performing hyperparameters achieved an accuracy of more than 98% at classifying mosquitoes, which showed no significant difference from human-level performance. We demonstrated the feasibility of the method to construct a model with the DCNN when deployed externally on mosquitoes in real time.

Abstract Introduction Scarring is the final common pathway for healing within the skin. Scars can be itchy, painful, tight, and disfiguring. Despite advances in surgery there is currently no reliably effective treatment for reducing or preventing scarring. The primary aim of this research is to assess the currently available models for scarring and evaluate/further develop the utility of current assessment tools, in an effort to design a pilot randomised control trial (RCT) for silicone gel treatment of scars. Method A systematic review of scar models in humans and animals. Examination of currently used subjective and objective scar assessment tools in a plastic surgery scar clinic. A retrospective cohort study assessing long-term scar outcomes in paediatric burn patients. Results Limitations and drawbacks of many existing methods to assess scar treatments were found. No statistically significant difference in long-term scarring outcomes was found between paediatric burns patients treated surgically versus conservatively. A RCT for silicone gel sheeting in the treatment of scars was set up and successful in recruitment. Conclusions Here, we have demonstrated difficulties in establishing a scientific scar treatment model; and created a pilot study that will help to provide high-quality evidence for the efficacy of silicone gel sheeting as a treatment for scars.
