Authors: Damanik Gerson , Sirat Djamhari , Gunawan Dadang 
Published: May 2023

Today, the use of communication system for public safety and regulation purposes is still narrowband based, that is communication that transmits low-speed voice and data services. Each government agency, such as the government of Jakarta (Pemda DKI), police, health department, re department, and the national disaster management agency, builds its own network independently. Therefore, it is difcult to coordinate the service between agencies if there is an emergency situation or disaster. Good communication system for public safety services will create conducive condition that will eventually create tranquility in the community. Jakarta, as the capital city of Indonesia, needs communication systems that create such condition. This paper determines the number of e-Node B for 700 MHz digital dividend network for Public Safety Communication services in Jakarta based on LTE technology. The services include voice, video, and data. In this study, it is assumed that determination of the required number of e-Node B is started from year 2012 to 2022 by considering the bit rate required by the public safety ocer. The assumption of ratio of public safety ocer in Jakarta is based on its population data. Radio network planning is based on coverage approach and capacity approach. The design of its coverage and capacity are analysed by using network dimensioning. Dimensioning coverage is conducted by calculating the link budget for dense urban, and urban areas. We use the 9955 RNP (Radio Network Planning) to calculate the link budget and predict the system's coverage. From the calculation, it is shown that e-Node B number required to cover the Jakarta area is 140. Dimensioning of capacity is based on the services bit rate required by the public safety ocer. The services are , voice, video, and data. Trac prole is based on the assumption in year 2012, 2015, and 2020. By the capacity calculation, it is shown that a total of 49 sites is required.

Published: May 2023

This paper presents a simulation study of Doubly Fed Induction Generator (DFIG) controlled by sliding mode control (SMC) applied to achieve control of active and reactive powers exchanged between the stator of the DFIG and the grid. In this paper, a variable speed wind turbine is considered with DFIG and dierent power electronic converter topologies: (i) Carried based Pulse Width Modulation (PWM), (ii) Space Vector Modulation (SVM). To improve the quality of energy injected into the electrical grid, we propose SVM technique which allows the minimizing of harmonics stator current and wide linear modu- lation range. The feasibility and eectiveness of the method is demonstrated by simulation results. The obtained results showed that, the proposed SMC with SVM inverter have stator and rotor current with low harmonic distortion and low active and reactive powers ripples than PWM inverter.
A Novel Modelling and Controlling of Distributed Power Flow Controller (DPFC) Base on PSO Algorithm
Authors: Ajami Ali , Soulat Behrouz , Safari Amin 
Published: May 2023

This paper focuses mainly on the state modelling controlling of a new FACTS device named Distributed Power Flow Controller (DPFC). The paper also discusses the role and function of DPFC in power ﬂow controlling together with its economic evaluation. DPFC is one of the Distributed FACTS (D-FACTS) devices. Its function is similar to that of UPFC but instead of one series converters, several low power series converters are used in DPFC. Therefore, DPFC includes multiple series converters and one shunt converter without common dc link. This eventually enables the DPFC to fully control all power system parameters. It, also, increases the reliability of the device and reduces its cost simultaneously. In this study a novel current injection model of DPFC is presented. The suggested model is suitable for steady state and stability studies. To use the presented model, a proper control system is needed. In this paper the PSO algorithm is used for optimal designing of controller parameters. Application of DPFC in diﬀerent operating conditions and failure in series converters are simulated with Matlab/Simulink software .The presented control system enables the DPFC to control the active and reactive power ﬂow at the transmission line independently. In conclusion, the resented simulation results show the validity and eﬀectiveness of suggested modelling and control system of DPFC for power ﬂow controlling.
Protection System Adjustment for High Penetration of Distributed Generation
Authors: Saksornchai Titti , Eua-arporn Bundhit 
Published: May 2023

Excessive number and capacity of Distributed Generation (DG) may cause problems to distribution systems. To maintain existing protection coordination, the system can generally allow DG to be connected at a limited capacity. In case of more DGs are to be connected, it is a challenging issue for distribution system engineers to conduct protection adjustment for which the system can allow increased level of DG penetration. This paper proposes three methods, concerning protection system adjustment, to allow high DG penetration, consisting of over-current protection resetting, directional recloser application, and fuse replacement with recloser. The rst method will help relieve the system constraint from existing pick-up current settings whereas the second one helps solve the problem of mis-operation of the mid-line recloser caused by DG back feed fault current. The nal method will be used to maintain fuse saving scheme. In this paper, the developed methods are simulated with a test system to illustrate their eectiveness on allowing higher penetration of DG to the system.
Optimal Designing of SSSC Based Supplementary Controller for LFO Damping of Power System Using COA
Authors: Mohammadzadeh Behrouz , Gholizadeh-Roshanagh Reza , Ravadanegh Sajad Najafi 
Published: May 2023

In this study a linearized Heffron-Phillips model of a single machine power system installed with a static synchronous series compensator (SSSC) has been presented. The optimal selection of the parameters for the SSSC controller is converted to an optimization problem which is solved by recently developed cuckoo optimization algorithm (COA). COA, as a new evolutionary optimization algorithm, is used in multiple applications. This optimization algorithm has a strong ability to find the most optimistic results for dynamic stability improvement. The effectiveness of the proposed controller for damping low frequency oscillations (LFO) is tested to variations in system loading and results compared with particle swarm optimization (PSO). The results analysis reveals that COA minimized multi objective cost function and improved dynamic stability, better than PSO. Also, performance of proposed COA controller in 10 times run is the same as in 1 time run. In addition, designed COA based SSSC damping controller has an excellent capability in damping low frequency oscillations and enhances rapidly and greatly the dynamic stability of the power systems.

Abstract
We perform an in-depth analysis of the recently validated TOI-3884 system, an M4-dwarf star with a transiting super-Neptune. Using high-precision light curves obtained with the 3.5 m Apache Point Observatory and radial velocity observations with the Habitable-zone Planet Finder, we derive a planetary mass of

and radius of 6.4 ± 0.2 R
⊕. We detect a distinct starspot crossing event occurring just after ingress and spanning half the transit for every transit. We determine this spot feature to be wavelength dependent with the amplitude and duration evolving slightly over time. Best-fit starspot models show that TOI-3884b possesses a misaligned (λ = 75° ± 10°) orbit that crosses a giant pole spot. This system presents a rare opportunity for studies into the nature of both a misaligned super-Neptune and spot evolution on an active mid-M dwarf.

Abstract
Planet formation imprints signatures on the physical structures of disks. In this paper, we present high-resolution (∼50 mas, 8 au) Atacama Large Millimeter/submillimeter Array observations of 1.3 mm dust continuum and CO line emission toward the disk around the M3.5 star 2MASS J04124068+2438157. The dust disk consists of only two narrow rings at radial distances of 0.″47 and 0.″78 (∼70 and 116 au), with Gaussian σ widths of 5.6 and 8.5 au, respectively. The width of the outer ring is smaller than the estimated pressure scale height by ∼25%, suggesting dust trapping in a radial pressure bump. The dust disk size, set by the location of the outermost ring, is significantly larger (by 3σ) than other disks with similar millimeter luminosity, which can be explained by an early formation of local pressure bump to stop radial drift of millimeter dust grains. After considering the disk’s physical structure and accretion properties, we prefer planet–disk interaction over dead zone or photoevaporation models to explain the observed dust disk morphology. We carry out high-contrast imaging at the

L
′

band using Keck/NIRC2 to search for potential young planets, but do not identify any source above 5σ. Within the dust gap between the two rings, we reach a contrast level of ∼7 mag, constraining the possible planet below ∼2–4 M
Jup. Analyses of the gap/ring properties suggest that an approximately Saturn-mass planet at ∼90 au is likely responsible for the formation of the outer ring, which can potentially be revealed with JWST.
Teorias dialógicas, minorias e pluralismo: uma reflexão com fundamento na filosofia constitucional do reconhecimento
Authors: Bunchaft Maria Eugenia , Ribeiro Moreira Eduardo 
Published: May 2023

A estratégia teórica de articular as reflexões sobre a Filosofia do Reconhecimento à Teoria da Constituição é um dos pilares fundamentais de um novo ramo do Direito denominado Filosofia Constitucional do Reconhecimento. O trabalho investiga o voto do ministro Barroso na ADPF 527 com base em uma estratégia que aposta na relação de complementaridade entre teorias dialógicas e métodos interseccionais à luz da Filosofia Constitucional do Reconhecimento. A Filosofia do Reconhecimento e a Teoria da Constituição possuem um substrato conceitual comum: o desafio do pluralismo, que marca sociedades multiculturais, e a necessidade de uma jurisdição constitucional que efetive direitos fundamentais de minorias vulneráveis. Portanto, o problema de pesquisa consiste no questionamento: como se expressou a relação entre estratégia dialógica e métodos interseccionais no voto do Ministro Barroso na ADPF 527? Considerando as contribuições da Filosofia Constitucional do Reconhecimento, sustenta-se a hipótese de que o voto do Ministro Barroso na ADPF 527, direcionado à efetivação de direitos fundamentais de grupos subalternizados, não foi capaz de articular o comportamento dialógico entre os Poderes a uma linguagem interseccional. Utiliza-se o método monográfico. A técnica de pesquisa é a documentação indireta, realizada por meio de consulta bibliográfica aos marcos teóricos de Post, Siegel, Habermas, Taylor e de outros autores. Utiliza-se a pesquisa documental.
Isolated Hepatobiliary Involvement in an Infant with Langerhans Cell Histiocytosis
Authors: Lakra Niva , Paul Abhik , Ghosh Ranajoy , Datta Supratim 
Published: May 2023

Background:
Langerhans cell histiocytosis (LCH) is a rare condition in which there is the proliferation of cells of the monocyte-dendritic cell lineage, including Langerhan's cells, with variable clinical manifestations and outcomes. Hepatic involvement is often seen as a part of multi-system LCH and is associated with a fulminant course. Isolated hepatobiliary involvement in LCH is rare.

Clinical Description:
We report an 11-month-old female infant presenting with prolonged fever associated with progressive jaundice, clay-colored stools, and a massive hepatomegaly. Liver biopsy showed CD1a and Langerin positivity. There was no other system involvement, and hence, the infant was diagnosed with a case of single-system LCH with isolated hepato-biliary LCH.

Management and Outcome:
A customized chemotherapeutic regimen was started with cytarabine and prednisolone. The patient has responded and there has been gradual improvement in the general clinical condition as well as the laboratory parameters.

Conclusions:
This case report creates the awareness of possible presentation of pediatric LCH with isolated liver involvement. A high index of suspicion, carefully customized chemotherapeutic regimen may help in the timely diagnosis and successful management.
Triptorelin-Induced Delayed Transient Arterial Hypertension
Authors: Gortan Anna Jolanda , Franco Francesca , Rodofile Federica , Cogo Paola 
Published: May 2023

Background:
Gonadotropin-releasing hormone analogs (GnRHas) such as triptorelin have been found to be effective and safe in the suppression of central precocious puberty (CPP). Only minor and transient side effects have been reported with depot preparation used in children.

Clinical Description:
We present three children with CPP who developed late onset hypertension 18–24 months after starting triptorelin, a long-acting GnRHa depot preparation. The secondary causes of hypertension were ruled out on the basis of clinical findings, appropriate blood tests, echocardiography, and abdominal ultrasound.

Management and Outcome:
After starting therapy with GnRHa, the children were evaluated routinely every 2–3 months for the 1st year, then every 6 months. They developed hypertension between 18 and 24 months after starting triptorelin. While therapy with triptorelin was stopped in all three children, only one of them was prescribed antihypertensive drug. The hypertension resolved gradually after discontinuation of triptorelin in all the children and antihypertensive was also omitted in the single case.

Conclusion:
Hypertension may be an adverse effect of triptorelin therapy and thus regular monitoring of blood pressure in children undergoing therapy with this drug for CPP is warranted.
Oropharyngeal Mucocele as an Unusual Cause of Recurrent Pneumonia in a Young Infant
Authors: Banerjee Amrita , Ghosh Dipyaman 
Published: May 2023

Background:
Oral mucoceles, though frequently seen as asymptomatic lesions in young adults, very little is known about their existence in infants and the complications arising out of them in this age group.

Clinical Description:
A 4-month-old infant presented with a history of recurrent episodes of breathing difficulty since 15 days of life, every episode being managed as aspiration pneumonia. The child presented in the fifth such episode with tachypnea tachycardia and chest indrawing. Auscultation revealed bilateral crepitations and chest X-ray showed diffuse haziness in the bilateral chest predominantly in the right middle lobe, rest of the systemic examination being normal. Oral cavity examination showed a bluish globular bulge behind the tongue with surrounding congested mucosa and thick secretions.

Management and Outcome:
The baby was managed with respiratory support in the form of continuous positive airway pressure, intravenous antibiotics Piperacillin-Tazobactam, amikacin and metronidazole, and anti-reflux measures of oral Domperidone. Flexible laryngoscopy showed a cystic lesion behind the tongue and contrast-enhanced computerized tomography confirmed a hypodense lesion arising from the uvula suggestive of a mucocele. Excision of the oro-pharyngeal cystic lesion was done and the histopathological examination confirmed it to be a mucocele. The baby was gradually weaned off oxygen support and proper breastfeeding was re-established.

Conclusion:
This case creates awareness regarding the fact that an unsuspected oral mucocele may be the cause of recurrent respiratory symptoms in an infant, thereby reiterating the importance of oral examination even in young infants.
A Case of Childhood Onset of Extended Sensory Ataxic Neuropathy, Dysarthria, and Ophthalmoparesis Phenotype with Pathogenic Polymerase Gamma Variation
Authors: Shah Ami , Kulkarni Shilpa , Mallakmir Snehal , Merchant Rashid 
Published: May 2023

Background:
Ataxia neuropathy spectrum, including sensory ataxia neuropathy, dysarthria, and ophthalmoparesis (SANDO), is a part of polymerase gamma (POLG) gene-related disorder, a heterogeneous group of mitochondrial disorders. Childhood onset of the SANDO phenotype is rare, and we describe such a case here, probably the first from India.

Clinical Description:
A 17-year-old girl presented with progressive gait abnormality since 5 years of age, later associated with ptosis and seizures. On examination, she had atrophy of distal small muscles and absent tendon reflexes in addition to ataxia and ptosis. Differentials for a neurodegenerative disorder with cognitive sparing and ophthalmoplegia were suspected.

Management:
Investigations revealed a mild elevation in serum lactate, transaminases, and creatine phosphokinase, with abnormal neurophysiology showing primary muscle disease with symmetrical sensorimotor polyneuropathy, and a normal neuroimaging. Gene sequencing analysis for the mitochondrial disorder was done, which revealed a pathogenic variation in the POLG gene. The child was kept on supportive management, including antiepileptics.

Conclusion:
This case shows that the SANDO phenotype of POLG-related disorders, classically seen in adults, may rarely be seen in children. Our case highlights the fact that although many of the progressive neurodegenerative disorders have a nonspecific clinical presentation, biomarkers, and neurophysiologic abnormalities, a few important phenotypic clues and awareness of POLG-related disorders may enable a pediatrician to order focused genetic testing to delineate the etiology.
Diffuse Alveolar Hemorrhage
Authors: Kulkarni Rajesh , Singh Rhea , Gohatre Himanshu , Kumar Arvind 
Published: May 2023

Background:
Diffuse lung disease (DLD), conventionally known as interstitial lung disease (ILD), encompasses a spectrum of diseases involving the pulmonary parenchyma with impairment of gaseous exchange. Most of the diseases under DLD have similar presentations, but appropriate investigations can delineate the exact disease. Diffuse alveolar hemorrhage (DAH) is one of the diseases under this umbrella group of DLD.

Clinical Description:
A 3-year-old girl suffering from persistent breathlessness and intermittent hypoxic exacerbations over 1 year, presented to us with acute respiratory worsening. She was underweight with stunting and had severe pallor. She had received blood transfusions in previous hospitalizations. Chest-X-ray shows reticular opacities, with High Resolution Computed Tomography (HRCT) chest showing bilateral diffuse ground glass opacities involving all lobes with the prominent pulmonary artery. The broncho-alveolar lavage showed hemosiderin-laden macrophages, thereby confirming alveolar hemorrhage. Antinuclear antibody was positive, though double-stranded DNA and Anti-neutrophil cytoplasmic antibody were negative. The child was thus diagnosed with a case of DAH, probably, immune mediated.

Management:
The child was treated with supportive care, including oxygen, intravenous fluids, antibiotics, and packed red cell transfusion. Even after improvement in hemoglobin, oxygen dependency persisted. The child was then administered Intravenous Immunoglobulin and prednisolone, to which the child showed a response with gradual weaning off oxygen.

Conclusions:
In any child presenting with persistent respiratory symptoms, especially exercise intolerance, over a prolonged period with intermittent hypoxic exacerbations, a pediatrician should consider diagnoses beyond infections and multitrigger wheezing. Such manifestations, particularly if associated with failure to thrive, may be due to DLD. DAH, a rare form of DLD, may be a possibility in such children.
Comparison of McGrath videolaryngoscope with conventional Macintosh laryngoscope for tracheal intubation in pediatric patients with normal airway
Authors: Bhamri Stuti , Desai Devyani , Chauhan Darshit , Cheraya Neha 
Published: May 2023

Background and Aims:
Videolaryngoscopes have attained prime importance in securing the airway in children in the present era. McGrath videolaryngoscope is available with single-use non-channeled fog-free disposable blades of various sizes showing its efficacy for intubation in adults but still lacunae in data related to children.

Materials and Methods:
In this prospective randomized controlled trial, a total of 88 children of the American Society of Anesthesiologists Grade I and II aged 1–10 years, weighing 10–20 kg undergoing general anesthesia were enrolled. Using the sealed envelope technique, the children were randomly allocated between Group G, in whom McGrath videolaryngoscope and Group M, in whom Macintosh laryngoscope was used for intubation. The primary aim was to compare intubation time between the two videolaryngoscopes. The secondary outcomes included glottic exposure time, Cormack and Lehane grading, number of attempts of intubation, intubation difficulty scale and complications. Statistical analysis was done using MedCalc software. The Student's t-test and Chi-square test were used for quantitative and categorical data, respectively.

Results:
The mean intubation time was comparable in both the groups (18.14 ± 17.80 s in Group G vs. 17.30 ± 16.74 s in Group M, P = 0.821). The mean time to glottic exposure was shorter (5.66 ± 4.58 vs. 8.50 ± 5.59 s, P = 0.0108) with decreased number of attempts of tube insertion and less incidences of trauma observed in patients with Group G as opposed to Group M. The Cormack and Lehane grading showed better glottic view in Group G.

Conclusion:
McGrath videolaryngoscope is as useful as the Macintosh laryngoscope for intubation in children with the added advantages of a better view of the larynx, lesser attempts to intubation, and fewer incidence of trauma.
