La expansión comercial de los satélites de comunicación
Authors: Sacristán Romero Francisco 
Published: January 2023

En los tiempos en que Estados Unidos y la desaparecida Unión Soviética se disputaban la hegemonía sobre el planeta, uno de los indicadores de poder fue el desarrollo de la industria espacial. Hoy el número de competidores se ha ampliado, de igual modo que crece el dominio estadounidense y han cambiado los objetivos: pisar otro planeta no aporta el beneficio que ofrecen los satélites en los campos de las telecomunicaciones, defensa o transportes. El objetivo de este artículo es ilustrar al lector acerca de las potencialidades económicas y comerciales que aportan los satélites de comunicación, pero también abordar los inconvenientes que ello genera, exponiendo de forma clara los productos y servicios más innovadores teniendo como referencias esencialmente los mercados de España y Estados Unidos.
La representación de los inmigrantes en la ficción televisiva en España. Propuesta para un análisis de contenido. El Comisario y Hospital Central
Authors: Galán Fajardo Elena 
Published: January 2023

En los últimos años el mapa demográfico de la sociedad española se ha modificado considerablemente, yendo hacia un modelo cada vez más heterogéneo y multicultural. En líneas generales, los medios de comunicación hegemónicos no han sabido, podido o querido recoger esta visión, evitando ceder la voz a los personajes inmigrantes, estereotipándolos y/o presentándolos en tramas de ilegalidad, exclusión o marginación.Esta investigación tiene como objeto de estudio analizar la imagen de los inmigrantes en la ficción televisiva, en concreto en dos títulos emitidos por la cadena Telecinco, desarrollados en entornos profesionales y con excelentes índices de audiencia en los últimos años: El Comisario y Hospital Central (1999-2005). Mediante el análisis de contenido de ambas series, se procede a la observación y al estudio de los estereotipos y representación de los inmigrantes. Por otro lado, se contrastan los datos con los procedentes del Instituto Nacional de Estadística en España. Como conclusión, se observa un empleo masivo de estereotipos negativos asociados a la imagen del inmigrante y una correlación entre realidad social y ficción televisiva.
Phytochemical Constituents, Haematological Activities and GC-MS Analysis of Isolated Oil of Rosary Pea (Abrus precatorius) in Wistar Rat Fed with High Lipid Diet
Authors: Iyekowa Osaro , Ndubuisi Opara V. 
Published: January 2023

The study is aimed at investigating the phytochemical constituents and haematological activities of the isolated oil in Wistar rat fed with high lipid diet. Powdered leaves of Abrus precatorious were extracted and phytochemical screening was done according to prescribed standard methods, while vacuum liquid chromatography (VLC) was adopted for oil isolation of the crude extract and characterized by gas chromatography-mass spectrometry (GC-MS). Thirty adult Wistar rats were randomly arranged into six groups (A, B, C, D, E and F) and treated under certain conditions. Haematological analyses were performed according to standard procedures. Saponins, alkaloids, terpenoids, flavonoids and glycosides were present. Oil constituents like octadecanoic acid (stearic acid) (35.30%), a saturated fatty acid was among the components detected in the isolated brown oil. There was a significant decrease (p < 0.05) in the levels of white blood cells (WBC) among the experimental groups (D and E), while mean corpsular haemoglobin (MCH) increased significantly (p < 0.05) with experimental group E (receiving high dose of the extract). This study indicated that methanol extract of A. precatorius can offer protection against blockage or plaques caused by high lipid diet.

Spatiotemporal Variability of Drought and its Relationships to ENSO and IOD Indices in Somaliland
Authors: Bile Mohamed S. , Limbu Paul 
Published: January 2023

Drought is one of Somaliland’s most prevalent natural hazards, causing serious socioeconomic and environmental harm. This study investigated the spatial and temporal variability of drought and its relationships with El Niño Southern Oscillation (ENSO) and Indian Ocean Dipole (IOD) indices using the Standardized Evapotranspiration Index (SPEI) from 1981 to 2020. The Mann-Kendall trend test and Sen's slope estimator were used to assess the trends of annual and seasonal SPEI time series. The Empirical Orthogonal Function (EOF) was employed to examine the dominant modes of the SPEI series, and Pearson and partial correlation analyses were performed to investigate the associations between significant modes of drought variability and ENSO and IOD indices. The results demonstrated a statistically significant downward trend of SPEI (increasing drought) at 99% confidence level. The EOF analysis indicated two spatially distinct zones of drought variability in the west and east of the country. Drought variability had a statistically significant negative correlation with ENSO in the summer and winter seasons, and with IOD in the winter season and annual time series. The findings of this study will provide important information for drought risk assessment, mitigation, and predictability in Somaliland.

Cryptogenic subdural empyema mimicking subacute-subdural hematoma on CT imaging in the pediatric group: a clinical case series
Authors: Jaweed Mohammad , Ying Dollicia Toh Ching , Rong Esther Sim Wan , Yasin Mohammad , Rosman Azmin Kass 
Published: January 2023

Introduction: Subdural empyema (SDE) is a rare but potentially life-threatening intracranial infection that is invariably fatal if left untreated. As clinical and radiologic features may be subtle or uncertain, early diagnosis may be a challenge but is crucial in reducing morbidity and mortality. SDE should always be suspected especially in a paediatric group with a history of fever, focal seizures, meningism and neurological deficit. The management of SDE has been debated in the literature for decades. Being one of the most serious neurosurgical emergencies, goals include surgical evacuation where both burr-hole drainage and craniotomy are primary surgical options, treatment of pus, and establishing the etiologic agent which subsequently guides antibiotic therapy for a favourable outcome.
Case presentation: We present three cases of immunocompetent patients, 4 and 6-month-old infants with a 14-year-old adolescent presenting with SDE without underlying risk factors. Non-contrast computed tomography imaging was equivocal for SDE. All of them required surgery. The two infants underwent burr holes and subsequently a wide craniotomy with intravenous antibiotics therapy while the adolescent required craniectomy because of swollen brain. They all had a favourable outcome on long term follow up.

Conclusion: Paediatric supratentorial SDE, although rapidly fatal if not identified promptly, can be effectively managed with early surgical drainage preferably craniotomy, eradication of the source, and sensitive IV broad-spectrum antibiotics. In this article, we discuss the clinical presentation, diagnostic tools, treatment options and outcomes for SDE with an emphasis on the challenges.

Introduction: Central Nervous System (CNS) malformations usually leave the family in disarray and doctors’ staff powerless. In developed countries, the rigorous application of preventive measures has contributed to a significant reduction incidence of these malformations. In African societies, mystical-religious considerations and low socio-economic level contribute to the increased occurrence of these malformations. The purpose of this work was to evaluate the prevalence and management of CNS malformations in our neurosurgical department.
Methods: This was a retrospective study conducted in the neurosurgery department of Yalgado Ouedraogo Teaching Hospital, in Ouagadougou, from 2016 to 2019. All cases of CNS malformations managed in the department with a workable medical record were reviewed.
Results: Five hundred and twenty-four cases were selected. The prevalence of malformations was 7.05%. The mean age of patients was 1.48 years (1 day and 76 years). Thirty-one (5.9%) cases of CNS malformations were diagnosed antenatally. One hundred and twenty-four (23.6%) ultrasounds (including 51 antenatal), 418 CT scans (79.7%) and 9 MRIs (1.7%) were performed. Hydrocephalus [(n = 219 (41.7%)] and spina bifida [(n = 213 (40.6%)] were the most common pathologies. Surgical treatment was indicated in 435 cases (83%) of which 179 (41.1%) could be operated. After a follow-up of 15.8 months, there were 46.3% sequelae identified.
Conclusion: CNS malformations are common in our context. They are not always prone to be treated surgically and are at the origin of many neurological sequelae and lifelong disability. Hence there is an urgent need to focus on improving preventive measures in Sub-Saharan Africa.

Sensitization of 316L Stainless Steel made by Laser Powder Bed Fusion Additive Manufacturing
Authors: Snitzer John , Lou Xiaoyuan 
Published: January 2023

Additively manufactured (AM) 316L stainless steel (SS) manufactured by laser powder bed fusion (L-PBF) and wrought 316L SS were subjected to sensitization heat treatments at 700°C up to 100 h. Using two evaluation methods, double-loop electrochemical potentiokinetic reactivation (DL-EPR) and ditching tests, degree of sensitization (DOS) and intergranular corrosion (IGC) susceptibility was evaluated. It was found that the wrought samples showed slightly lower IGC susceptibility compared to their AM counterpart. DOS and IGC attacks increased with sensitization time for all samples. Dislocation cellular structures were found to have little to no impact on DOS and IGC for the AM samples. Sensitized at 100 h, the AM sample showed significant Cr depletion along high-angle grain boundaries (12.35 wt% on average) and exhibited Cr carbide precipitation. Mo-rich particles along grain boundaries were also observed. The DL-EPR test attacks the surface oxide film and grain boundaries while the ditching test attacks the melt pool boundaries and grain boundaries (IGC and pitting). Changes to the DL-EPR and ditching standards for AM application have been proposed in this work.

IntroductionTo compare the posterior fossa measurements of Chiari type I malformation (CHM1) patients with and without syrinx and with a control group.Material and methodsThe patients with syrinx were divided into 2 groupd according to syrinx width/cord width (S/C) ratios: group 1 – S/C ratio < 50%; group 2 – S/C ratio > 50%. The length of the clivus, the AP length of the foramen magnum, the AP length of the posterior fossa, the perpendicular distance between the McRae line and (a) the splenium of corpus callosum, (b) the pons, and (c) the fastigium of the 160 patients and of the 160 control patients were statistically compared. In addition, the measurements of the patients with and without syrinx, according to the S/C ratio, were statistically compared.ResultsSyrinx was present in 59 (36.8 %) of the 160 patients. The S/C ratio was < 50% in 30 (50.9 %) of them, and S/C ratio > 50% in 29 (49.1%) of them. All the measurements in the patient group, except of the AP length of the foramen magnum, were statistically significantly lower than in the control group (p = 0.001). There was no significant difference in the measurements of the patients with syrinx group 1 and the patients without syrinx, but the AP length of posterior fossa was statistically significantly lower in the patients with syrinx group 2 than the patients without syrinx (p = 0.03).ConclusionsThe S/C ratio can be a guide to the underlying aetiology.

Published: January 2023

A produção de biomassa em áreas de Caatinga apresenta grande variação espacial e sazonal, principalmente em função da distribuição das chuvas. Diante da diminuição da vegetação de Caatinga no nordeste brasileiro e ao consequente avanço da desertificação em todo o bioma, o presente estudo analisou qual tem sido o sequestro de carbono para o período de 2001 a 2019, em quatro áreas localizadas ao norte (A1), leste (A2), sul (A3) e oeste (A4) do bioma, e o que pode estar conduzindo com maior influência seu aumento ou diminuição. Através da análise com dados de sensoriamento remoto de produtividade primária bruta (PPB) e líquida (PPL), provenientes do MODIS, e dados de clima obtidos do NCEP e estações meteorológicas, observou-se que estão havendo uma redução das chuvas em todas as áreas, um aumento da temperatura do ar e redução de absorção de carbono pela biomassa. O teste de Mann-Kendall foi aplicado para verificar o nível de significância destas mudanças e constatamos que os resultados foram estatisticamente significativos somente para A2. Também se verificou que a variável determinante no crescimento da vegetação de Caatinga é a chuva. Mesmo com baixa significância estatística para a maior parte das áreas, foi verificado que a PPB e PPL estão reduzindo para A1, A2 e A4 como possível consequência desta mudança no clima. Em A3 onde se observou aumento no sequestro de carbono, provavelmente devido a hidrologia local, o que está fazendo com que esta área de Caatinga seja resiliente mesmo em períodos de seca.
The Evolution of Seismic Design Provisions in Indonesia’s National Bridge Code

Published: January 2023

To accommodate increased seismic hazards in Indonesia, provisions regarding structural details on seismic regulations have been tightened. In this paper, the variations in seismic hazard and detailing requirements from bridge code era before 1990 to the present was provided. To examine the bridge performance, pushover analysis was carried out based on the latest bridge code SNI 2833:2016/Seismic Map 2017. From the analysis results, the performance of older bridges would typically be less than more recently designed structures. The performance level of the bridge in the era before SNI 2833:2016/Seismic Map 2017 will be Operational-Life Safety (LS) whereas the performance level of the bridge designed with SNI 2833:2016 will be Elastic – Operational. Referring to NCHRP 949 for bridge performance level evaluation, results show that the performance level of the bridge still satisfies the requirement, which is Life Safety under upper-level earthquake. Therefore, the existing bridge shows adequate capacity under the current seismic load Seismic Map 2017 (7% probability of exceedance in 75 years (RP= 1000 years)). Evaluation of seismic vulnerability needs to be done to ensure the safety of the existing bridges in Indonesia, most of which are located in earthquake-prone areas, especially those that were designed with older version regulations.
