Abstract
Diarrhea caused by multidrug-resistant Escherichia coli (E. coli) is an important and common problem in companion animals, especially dogs. Moreover, these dogs may serve as a reservoir of pathogenic strains of E. coli that may cause enteric and extra-intestinal infections in humans and other animals. This study was conducted to investigate the antibiotic susceptibility pattern of E. coli isolates from diarrheic dogs in Maiduguri Metropolis, Borno State, Nigeria. In fecal samples of 200 dogs with diarrhea, 147 E. coli strains (73.5%) were isolated and characterized by the standard bacteriological techniques (culture, biochemical tests, and antimicrobial susceptibility testing). Out of the 147 positive isolates, 45, 50, and 52 were from Elkanemi Park, Magaram, and Sabon gari wards respectively. The isolates show 100% resistance to chloramphenicol, cefuroxime, and ceftriaxone, 96.6% to amoxicillin, and 95.9% to gentamicin, while all (100%) were susceptible to ciprofloxacin. All the isolates showed multiple antimicrobial resistance. The result of the current study showed that dogs in Maiduguri are important reservoirs of multidrug-resistant E. coli. Therefore, it is important to adopt and apply guidelines for the correct use of antimicrobials in small animal practice to reduce the emergence of multidrug resistance among E. coli in companion animals.
Process of local government fragmentation in Croatia: From a big-bang to a status quo
Authors: Škarica Mihovil 
Published: January 2021

Abstract
The paper explores and explains the fragmentation process in Croatian local government during the transition period from 1990 onwards. Special focus is given to the emergence of new municipalities (municipal splits/secessions) that occurred after the new two-tier local government system was established in 1993. Excessive fragmentation of territorial structure at the beginning of the 1990s was a systematic and centrally driven reform that was meant to break with the inherited local government model and break up its territorial structure as radically as possible. While the initial overhaul in 1993 was mostly the result of conscious policy implemented in a top-down manner, subsequent municipal splits were mostly the outcome of local initiatives and lobbying, and were predominantly shaped by local, primarily economic factors, whereas political and cultural factors were of secondary importance. The national institutional context, including criteria and procedural rules for splits, were quite liberal during this whole period, with a moderate tightening-up trajectory. The number of municipalities finally stabilised in 2006, since when there have been no more splits.
Facile preparation of Co@Co3O4@Nitrogen doped carbon composite from ionic liquid as anode material for high performance lithium-ion batteries

Published: January 2021

Abstract
Co@Co3O4@Nitrogen doped carbon (Co@Co3O4@NDC) composite is synthesized by high temperature carbonization of ionic liquids followed by low temperature thermal oxidation. In the process of high temperature carbonization, cobalt ions are reduced to metallic cobalt, producing Co@Nitrogen doped carbon (Co@NDC). Co@Co3O4@NDC composite is obtained after low temperature oxidation, in which a part of the metallic cobalt is oxidized to Co3O4. The structural characterizations indicate that the composite is composed of three crystalline phases (carbon, Co and Co3O4). The results of transmission electron microscopy study show that the carbon materials not only coat the Co@Co3O4 nanoparticles, but also form carbon network that connects the Co@Co3O4 nanoparticles. This conductive carbon network is beneficial to improve the electrochemical performance of the composite. The electrochemical test results show that the Co@Co3O4@NDC composite exhibits excellent electrochemical performance, delivering the discharge capacities of 790 and 304 mAh˙g−1 after 1500 cycles at 5 C and 10 C. This excellent electrochemical performance is due to synergistic effects of Co3O4, cobalt nanoparticles embedded in carbon which has high conductivity, and nitrogen functional groups.
Hybrid white light emitting devices (HWLEDs) from organic polymer and PbS nanocrystals by multiple excitons
Authors: Kadim Akeel M. 
Published: January 2021

Abstract
Hybrid white light-emitting devices (HWLEDs) were fabricated using FTO/PEDOT: PSS/PbS/Alq3/Ni system and synthesized by phase separation process. In the present study, the multiple excitons generation in lead sulfide (PbS) NCs, which is characteristic of PbS NCs, was used to induce an effective and regulated energy transfer to an HWLED. The HWLED consisted of three layers successively deposited on FTO glass substrate; the first layer consisted of poly (3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT: PSS) blended with polymethyl methacrylate (PMMA) organic polymer in the 1:1 ratio, while the second layer consisted of PbS NCs. Finally, above the layer of the PbS NCs, Tris (8-hydroxyquinoline) aluminum (Alq3) layer was deposited. The white light was generated with quite a good efficiency due to the confinement effect that makes the energy gap greater. The characteristics of the current-voltage (I-V) indicate acceptable conditions for the generation of white light by multiple excitons. It was found that the emission levels able to produce white luminescence, classified based on the coordinate system of chromaticity (CIE 1931), are x = 0.31, y = 0.33 while the correlated color temperature (CCT) is about 6250 K. The HWLEDs made from PbS NCs with hole injection from the organic polymer (PEDOT: PSS with PMMA), and electron injection from organic molecules (Alq3) are capable of white light generation.

Authors: Coronado Pluvio J. , Santiago-López Javier de , Santiago-García Javier de , Méndez Ramiro , Fasero Maria , Herraiz Miguel A. 
Published: January 2021

Abstract

Background
The aim of the study was to determine if the endometrial tumor volume (TV) measured by magnetic resonance imaging (MRI-TV) is associated with survival in endometrial cancer and lymph nodes metastases (LN+).

Patients and methods
We evaluated the MRI imaging and records of 341 women with endometrial cancer and preoperative MRI from 2008 to 2018. The MRI-TV was calculated using the ellipsoid formula measuring three perpendicular tumor diameters. Tumor myometrial invasion was also analyzed.

Results
Higher MRI-TV was associated with age ≥ 65y, non-endometrioid tumors, grade-3, deep-myometrial invasion, LN+ and advanced FIGO stage. There were 37 patients with LN+ (8.8%). Non-endometrioid tumors, deep-myometrial invasion, grade-3 and MRI-TV ≥ 10 cm3 were the factors associated with LN+. Using a receiver operating characteristic [ROC] curve, the MRI-TV cut-off for survival was 10 cm3 (area under curve [AUC] = 0.70; 95% CI: 0.61–0.73). 5 years disease-free (DFS) and overall survival (OS) was significantly lower in MRI-TV ≥ 10 cm3 (69.3% vs. 84.5%, and 75.4% vs. 96.1%, respectively). MRI-TV was considered an independent factor of DFS (HR: 2.20, 95% CI: 1.09–4.45, p = 0.029) and OS (HR: 3.88, 95% CI: 1.34–11.24, p = 0.012) in multivariate analysis.

Conclusions
MRI-TV was associated with LN+, and MRI-TV ≥ 10 cm3 was an independent prognostic factor of lower DFS and OS. The MRI-TV can be auxiliary information to plan the surgery strategy and predict the adjuvant treatment in women with endometrial cancer.

Abstract

Background
The aim of study was to establish the typical radiation quantity values for the most common trauma orthopaedic surgical procedures and to compare them with reference values of equivalent procedures performed in other institutions. In addition, we assess the impact of image intensifier and flat panel detector technology used for fluoroscopically guidance on patient exposure.

Materials and methods
Five most frequently performed fluoroscopically guided trauma orthopaedic procedures in University Medical Centre Ljubljana were analysed. Data on 199 cases over a 6 months period from December 2016 to June 2017 were gathered retrospectively. Study covered 40 dynamic hip screw fixations (DHS), 23 proximal femoral nail insertions (PFN), 20 proximal humeral nail insertions (PHN), 77 partial hip endoprosthesis implantations (PEP) and 39 percutaneous posterior spine fixations (PPS). The median and average along with the first and third quartile values of air kerma area product (KAP) for each procedure type were calculated as well as median and average value of fluoroscopy screening time.

Results
Typical KAP value for dynamic hip screw fixation was set at 0.52 Gycm2; for proximal femoral nail insertion at 0.53 Gycm2 and for proximal humeral nail insertion at 0.26 Gycm2. For implantation of partial endoprosthesis typical KAP value utilizing flat panel technology was set at 0.08 Gycm2 and at 0.21 Gycm2 when the image intensifier technology was used. Typical KAP value for percutaneous posterior spine fixation was set at 1.26 Gycm2, using flat panel technology and at 3.98 Gycm2 using image intensifier technology.

Conclusions
Established typical KAP levels of surgical orthopaedic procedures in traumatology will serve as a valuable tool for further radiation exposure optimization.

Published: January 2021

Background:
Spontaneous subcutaneous emphysema (SSE) is a clinical condition in which air escapes into the subcutaneous tissues. It is a rare complication of childhood pneumonia and often occurs with pneumothorax and/or pneumomediastinum. Although the sight of a child with SSE could be frightening, it is mostly benign requiring in most cases supportive care. We report a case of SSE complicating pneumonia in an 18-month-old toddler that was managed conservatively.

Case Report:
An 18-months-old toddler was admitted with a 5-day history of progressive swelling of the face, scalp, upper limbs, and trunk. He was referred from a peripheral hospital where he was admitted for 5 days with pneumonia and had received antibiotics, intravenous fluid, and oxygen therapy. Clinical evaluation revealed extensive subcutaneous emphysema and right-sided pneumothorax. Antibiotics were optimized and the patient was provided supportive care and monitored for 7 days with complete resolution of the emphysema.

Conclusion:
SSE could complicate childhood pneumonia but it has a benign course. Effective treatment of underlying pneumonia alongside supportive care will achieve complete resolution.

ABSTRAKPenelitian kali ini mengamati data Operating Support System (OSS) operator untuk wilayah Ciparay Bandung. Berdasarkan data OSS, Ciparay memiliki penetrasi jaringan LTE-A sebesar 90%, hal ini menunjukkan bahwa trafik di area tersebut sangat padat. Selain itu, nilai throughput jaringan LTE-A di area ini hanya sebesar 6.8 Mbps. Hal ini masih belum memenuhi standar operator dimana throughput > 16 Mbps. Untuk mengatasi hal ini, dilakukan optimalisasi penggunaan frekuensi dan peningkatan throughput menggunakan metode Carrier Aggregation Deployment Scenario 2 (CADS2) dimana dilakukan penggabungan dua buah component carrier pada bandwidth 15 MHz di band 3 (1800 MHz) dan bandwidth 20 di band 40 (2300 MHz). Dimana pada skenario I, band 3 dijadikan primary cell dan band 40 dijadikan secondary cell. Sedangkan pada skenario II, band 40 dijadikan primay cell dan band 3 dijadikan secondary cell. Hasil yang diperoleh yaitu terjadi peningkatan rata-rata throughput sebesar 94,87 %.Kata kunci: LTE-A, OSS operator, CADS2, throughput, Ciparay Bandung ABSTRACTThis research examines operator Operating Support System (OSS) data for the Ciparay area of Bandung. Based on OSS data, Ciparay has an LTE-A network penetration of 90%, this shows that the traffic in the area is very dense. In addition, the value of LTE-A network throughput in this area is only 6.8 Mbps. This still does not meet operator standards where throughput is> 16 Mbps. To overcome this, optimization of frequency usage and increase in throughput are carried out using the Carrier Aggregation Deployment Scenario 2 (CADS2) method by combining two carrier components on a 15 MHz bandwidth in band 3 (1800 MHz) and bandwidth 20 in band 40 (2300 MHz) . In scenario I, band 3 is set as a primary cell and band 40 is set as a secondary cell, whereas in scenario II, band 40 is set as a primay cell and band 3 is set as a secondary cell.

Penelitian ini dilatarbelakangi oleh realitas yang memprihatinkan dan memerlukan perhatian, yaitu kesalahan suami dalam bertindak ketika menghadapi istri yang Nusyuz sehingga berujung pada kekerasan dalam rumah tangga. Hal ini mendorong penulis untuk mengemukakan kembali bagaimana seharusnya tindakan yang dilakukan oleh suami ketika menghadapi istri yang Nusyuz berdasarkan Al-Quran dengan mengemukakan penyelesaian terhadap Nusyuz istri khususnya perbandingan antara Tafsir Al-Maraghi dan Tafsir Al-Misbah. Pendekatan penelitian yang penulis gunakan adalah (library research) dalam tekhnis deskriptif kualitatif eksploratif, dengan menekankan pada sumber tertulis terutama Tafsir Al-Maraghi dan Tafsir Al-Misbah. Penelitian ini menggunakan tekhnik pengumpulan data dokumentasi dengan menerapkan tekhnik analisis data kerangka berfikir metode komparatif yaitu dengan menentukan objek, menjelaskan konteks, melakukan kajian perbandingan, mencari argument dibalik perbedaan dan menyampaikan kesimpuan. Hasilnya penulis menemukan bahwa ketika menghadapi istri yang Nusyuz berdasarkan QS.An- Nisa’:34 menurut Tafsir Al-Maraghi dan Tafsir Al-Misbah suami dapat melakukan beberapa langkah, pertama, menasehati atau memberi nasehat kepada istri dengan kata yang lemah lembut kedua, menunjukkan ketidaksenangan suami terhadap sikap istri dengan cara seperti, tidak menggauli istri atau menghindari berhubungan seks, tidak ada cumbu danmenghindari hal-hal yang biasanya dilakukan suami kepada istri misalnya merayu istri, ketiga, pisah ranjang atau memisahkan diri dari tempat tidur, keempat, bermusyawarah antara pihak suami dan istri, kelima, jika semua yang di atas tidak dapat merubah sikap Nusyuz istri maka suami boleh memukul dengan kata lain memang sudah tidak ada jalan lain lagi bagi suami namun, yang perlu diingat oleh suami ialah memukul dengan pukulan yang dibenarkan dalam Islam.
