Energy Consumption and CO2 Emissions Related to Wine Production: The Case Study of a Winery in Douro Wine Region-Portugal
Authors: Matos Cristina , Pirra António
Published: April 2022

Water use and its associated energy consumption in wine processes are often unnoticed in best practice. Many proprietors are insensitive to how water is used within their winery procedures. Key areas of environmental concern currently faced by the wine industry include water and energy use and the production of greenhouse effect gas emissions, among others. This review revealed that the practice within wine organizations tends to be largely unexplored and inadequate. To address the present needs for accurate water and energy resources control, it is vital to develop research on how water and energy are related and used in wine production to increase the effective use of these resources, minimizing the related environmental impact. The main aim of this paper was to find the relationship between energy and water utilization and subsequent CO2 emissions from a winery located in the Douro Valley, contributing to its sustainability in terms of resources consumption. A two-year monitoring plan on water use was implemented, and the related energy consumption and CO2 emissions were calculated. The results showed high values of energy (148.5 kWh/day) as well as related CO2 emissions (54 kg CO2/day) associated with high water consumption (that ranged from 16.20 to 27.66 m3 water/day). This information is very important and contributes to enlarging the database of environmental parameters related to wine production in the Douro wine region, creating opportunities for environmental improvement.

Published: April 2022

Hip dysplasia (HD) is a typical developmental abnormality of the hip joint, and discomfort is often found in adulthood. This study compared patients with symptomatic HD in muscle strength, dynamic balance, and range of motion (ROM) with healthy individuals. Patients included those who complained of unilateral pain although the lateral center edge angle (LCEA) exhibited bilateral abnormality. Participants (n = 95; men: 46, women: 49) were divided into symptomatic and asymptomatic sides, and a healthy group without a history of hip joint disease (n = 70; men: 30, women: 40) was compared. Hip flexion, extension, abduction, and adduction were performed at an angular velocity of 30°/s using an isokinetic strength test device. The Y-balance test was conducted to measure dynamic balance, and ROM was measured using an electronic goniometer to evaluate flexion, extension, adduction, abduction, and internal and external rotations. In addition, the pain visual analog scale (VAS) and hip and groin outcome scale (HAGOS), a subjective evaluation of the hip joint, were evaluated. ROM (flexion, abduction, internal rotation, and external rotation) was significantly decreased in the HD symptomatic sides of men and women compared to those of the healthy group and the asymptomatic side, and the dynamic balance, flexion, and abduction muscle strength were also lower on the symptomatic sides. Although the LCEA of the HD asymptomatic side was lower than that of the healthy group, there were no significant differences in VAS, flexion, extension, abduction ROM, and extension strength compared to those of healthy individuals. In conclusion, patients with HD were mostly bilateral, and on the symptomatic side, there was a decrease in ROM, dynamic balance, and muscle strength; however, on the asymptomatic side, the function was relatively close to normal.
Kinematic Geometry of Timelike Ruled Surfaces in Minkowski 3-Space E13
Authors: Alluhaibi Nadia , Abdel-Baky Rashad A.
Published: April 2022

Symmetry is a frequently recurring theme in mathematics, nature, science, etc. In mathematics, its most familiar manifestation appears in geometry, most notably line geometry, and in other closely related areas. In this study, we take advantage of the symmetry properties of both dual space and original space in order to transfer problems in original space to dual space. We use E. Study Mappingas a direct method for analyzing the kinematic geometry of timelike ruled and developable surfaces. Then, the invariants for a spacelike line trajectory are studied and the well-known formulae of Hamilton and Mannheim on the theory of surfaces are provenfor the line space. Meanwhile, a timelike Plücker conoid generated by the Disteli-axis is derived and its kinematic geometry is discussed. Finally, some equations for particular timelike ruled surfaces, such as the general timelike helicoid, the Lorentzian sphere, and the timelike cone, are derived and plotted.
West Nile Virus Neuroinfection in Humans: Peripheral Biomarkers of Neuroinflammation and Neuronal Damage
Authors: Constant Orianne , Barthelemy Jonathan , Nagy Anna , Salinas Sara , Simonin Yannick
Published: April 2022

Among emerging arthropod-borne viruses (arbovirus), West Nile virus (WNV) is a flavivirus that can be associated with severe neuroinvasive infections in humans. In 2018, the European WNV epidemic resulted in over 2000 cases, representing the most important arboviral epidemic in the European continent. Characterization of inflammation and neuronal biomarkers released during WNV infection, especially in the context of neuronal impairments, could provide insight into the development of predictive tools that could be beneficial for patient outcomes. We first analyzed the inflammatory signature in the serum of WNV-infected mice and found increased concentrations of several inflammatory cytokines. We next analyzed serum and cerebrospinal-fluid (CSF) samples from a cohort of patients infected by WNV between 2018 and 2019 in Hungary to quantify a large panel of inflammatory cytokines and neurological factors. We found higher levels of inflammatory cytokines (e.g., IL4, IL6, and IL10) and neuronal factors (e.g., BDNF, GFAP, MIF, TDP-43) in the sera of WNV-infected patients with neuroinvasive disease. Furthermore, the serum inflammatory profile of these patients persisted for several weeks after initial infection, potentially leading to long-term sequelae and having a deleterious effect on brain neurovasculature. This work suggests that early signs of increased serum concentrations of inflammatory cytokines and neuronal factors could be a signature underlying the development of severe neurological impairments. Biomarkers could play an important role in patient monitoring to improve care and prevent undesirable outcomes.

Authors: Nalin Shrish , Sahu Anurag , Gupta Kanika , Singh Kulwant
Published: April 2022

Background: Chronic subdural hematoma (CSDH) is a well-known entity and common surgical disorder managed by the neurosurgeon and, if not recognized and treated timely, may prove fatal. It can be non-traumatic or post-traumatic and all of them need urgent attention irrespective of aetiology. It manifests with a progressive neurologic deficit that occurs >3 weeks following head injury. The principal techniques used in the treatment of CSDHs presently are burr hole, twist drill craniostomy, craniectomy and craniotomy.
Objective: The aim of this study was to assess clinical outcome in unilateral chronic subdural hematoma patients treated by single or double burr-hole drainage. This prospective study was carried out at the Department of Neurosurgery, IMS, BHU, Varanasi from September 2016 to August 2018. A total of 60 patients with their age ranged from 22to 88 years with GCS 6 to 15 & hematoma thickness 10mmc were included in this study and randomly divided into two groups using random allocation software. In group A, patients with chronic subdural hematoma (CSDH) were managed with single burr-hole drainage. In group B, patients were managed with double burr-hole drainage. Clinical outcome was measured on the1st postoperative day, 3rd postoperative day and 7th postoperative day by GCS and at 1month follow-up by measuring the Glasgow outcome scale (GOS).
Result: In this study double burr-hole drainage and single burr-hole drainage surgery shows equal success in the management of CSDHs with single burr hole taking less operative time.

We report a case of upper cervical spine tuberculosis of the atlantoaxial facet joint.
Spectrum of non-traumatic craniovertebral junction disorders
Authors: Singh Neha , Singh Deepak Kumar
Published: April 2022

Introduction: Craniovertebral junction is the “zone of transition” between the skull and cervical spine so its detailed discussion is lacking in so many standard textbooks addressing these regions. These anomalies are especially common in the Indian subcontinent. Accurate diagnosis, probable aetiology and pre-treatment evaluation considerably affect the prognosis of patients. The aim of this study was to classify various Craniovertebral junction disorders according to their aetiology and to correlate the imaging findings with the clinical profile of the patients and histopathology whenever possible.

Methods: This prospective observational study was done in our department over the period of one year from August 2016 to July 2017. 57 North Indian patients from all age groups and both sex, who had imaging features suggesting craniovertebral junction pathology were selected for the study.

Results: Our study group comprised 34 males and 23 females with a male to female ratio of 1.47: 1. The most common age group was 11-20 years and the most common aetiology being developmental followed by infective, autoimmune and inflammatory disorders.

Conclusions: CVJ abnormalities are a group of treatable neurological disorders, and are approached with much caution by clinicians. Thus, it is crucial that radiologists should be able to make a precise diagnosis, categorize them into etiological groups, and give precise anatomical information on MDCT and/or MRI, as this information ultimately helps determine the management of such abnormalities and their prognosis.

Authors: Iacob G.
Published: April 2022

Introduction: Aqueduct stenosis (AS) in old people is a rare pathological entity. I report a case of a 66 years old woman with severe ataxia, cognitive deterioration, loss of sphincters control (gatism). Clinical, neuro-radiologic and therapeutic considerations are discussed.

Case presentation: A 66 years old woman with a 6 months history of mild cerebral trauma by car accident without losing consciousness, present 2 months before hospitalization severe ataxia, cognitive disorders, gatism. At the time of trauma, brain scanner performed in another institution showed minimal fronto-basal cerebral contusions and blood collection around the brain stem. One month after a new unenhanced brain scan all previous lesions are gone. At admission, an abnormal enlargement of lateral and third ventricles are remarked both on unenhanced CT and MRI scan of the brain explained by cerebral aqueductal stenosis. Ventricular open pressure was 350 mm H2O. A ventriculoperitoneal shunt with a variable pressure valve was installed. The surgery went uneventful and the patient recovered as expected. 6-month follow-up visit the patient was symptom-free, with a fine intellectual recovery.

Published: April 2022

Nimodipine is a drug belonging to the group of calcium channel blockers, very well tolerated, widely recognized for its central action as a vasodilator preventing vasospasm secondary to aneurysmal subarachnoid haemorrhage. It is currently approved as a drug used in the treatment of this type of haemorrhage, mainly because it is effective in reducing neurological deficits due to delayed cerebral ischemia. In addition, due to its relaxing action on the cerebral vascular musculature and its facility to cross the blood-brain barrier, it has multiple functions in other types of cerebral vascular lesions such as ischemic stroke and other neurological conditions involving stress or cell death. Its role as a prophylactic agent in the treatment of migraine and its effect as a neuroprotective agent have also been evaluated.

Aim: Awake craniotomy has been proven to be safe and effective. It has generally been used for non-edematous conditions. If done in edematous states, large craniotomies are advised. Here, we report the combined use of techniques of awake anaesthesia and focussed craniotomy for dealing with large/edematous brain lesions.
Materials and Methods: This was a prospective single-centre study from May to October 2019. Included were adult cooperative patients presenting with edematous brain lesions. A completely awake cycle was used using ring scalp block, Dexmedetomidine loading, and maintenance infusion, and use of Midazolam and Fentanyl. The dural flap was lifted limited to the lesion, and sometimes in stages to tackle the bulging brain. Data was collected for resection volume, pain scores using visual analogue scale (VAS) during the surgery, seizures, complications, new deficits, blood loss, duration of surgery, ICU, and postoperative hospital stay.
Results: Fifteen patients underwent the procedure. Pathologies were high-grade gliomas (7), low-grade gliomas (3), tuberculoma (2), metastasis (1), ependymoma (1), and meningioma (1). Fourteen patients underwent total, and one underwent subtotal excision. Brain bulge could be handled with the staged opening of the dura and intratumoral decompression. No patient required postoperative ventilatory support. Intraoperative pain scores ranged from 2-3. The duration of surgery ranged from 60-280min. Blood loss ranged from 75-300ml. Postoperative stay varied from 3-20 days. There were two intraoperative seizures (managed), two CSF leaks, and two infections. Two patients developed transitory motor deficits.
Conclusion: Awake focussed craniotomy was found safe and effective for large/edematous brain lesions in appropriately selected patients.

Published: April 2022

Objective: Covid19 pandemic challenged the global healthcare system and both developed and developing countries responded with their might to fight this global pandemic. Road traffic accidents are a major cause of morbidity and mortality in India and we studied the impact of lockdown on neurosurgery trauma patients in a tertiary care centre in India.
Methods: Indian government announced complete lockdown on 25th march 2020 and India remained in complete lockdown till 31st May 2020. We included the patients admitted from 1st January 2020 to 24th March 2020 in pre lockdown period and25th march to  In this cross-sectional study we divided the patients into two groups of pre lockdown and lockdown period and incidence of neurosurgery trauma patients was assessed for Road Traffic Accident, assault, hit by animal and fall from height.
Result: In our study 491 patients were admitted in pre lockdown and 369 patients were admitted in lockdown period. Road traffic accident patients were more in pre lockdown 39.5% (n=194) as compared to lockdown period 31.2% (n=115). However, cases of assaults were more in the lockdown period (14.6%, n=54) as compared to pre lockdown (3.9%, n=19). The death rate in neurosurgery trauma patients reduced significantly in lockdown (7.3%, n=27) as compared to pre lockdown (21.8%, n=107).
Conclusion: The COVID19 pandemic induced lockdown resulted in a decrease in motor vehicle movements which further decreased the incidence of RTA and related trauma however incidence of assault-related trauma and cases increased significantly in this period. The overall outcome of such patients improved probably due to better utilization of available health care facilities.

Published: April 2022

The extent and progression of neurological impairment in traumatic brain injury depend significantly on the area of perilesional gloom, where neuronal apoptosis occurs. Inhibition of apoptosis becomes a therapeutic strategy to preserve brain tissue and promote functional recovery. Hyperbaric oxygen therapy is a treatment by which 100% oxygen is administered, with the aim of achieving a higher pressure than atmospheric pressure at sea level, to decrease ischemia and intensity of inflammatory processes triggered, compromising the viability of the tissues. For mild traumatic brain injury, studies indicate that hyperbaric oxygen therapy is no better than sham treatment. For acute treatment of moderate to severe traumatic brain injury, although the methodology is questionable in certain studies due to the complexity of the brain injury, hyperbaric oxygen therapy has been shown to be beneficial as a relatively safe adjunctive therapy. The objective of this review is to discuss aspects related to the pathophysiology of traumatic brain injury, the mechanism of action of hyperbaric oxygen therapy, and correlate these results with the use of this therapy in the prevention of neuronal injury, supported by original studies reported in the scientific literature

Published: April 2022

The advancement of intracranial stent technology and techniques has extended the applications of endovascular coiling methods for complex intracranial aneurysms. Coiling of wide-necked and complex bifurcation aneurysms usually requires double stent implantation. Different configurations for double stent-assisted coil embolization have been described. The T-configuration stent-assisted coiling procedure was recently described as a feasible, effective, and relatively safe endovascular technique used to treat wide-necked complex bifurcation aneurysms. In this article, we present the successful management of a complex wide-neck basilar tip aneurysm using a slightly modified T-configuration stent-assisted coiling technique.

Introduction: In this study, it is aimed to present a very rare liver subcapsular accumulation of a patient after ventriculoperitoneal shunt surgery who was diagnosed with Pseudotumor cerebri syndrome with progressive sight loss.    

Case: The patient is a 38-year-old female who was diagnosed with lomber spondylose and later operated with stabilization and fusion surgery. Seven days after the operation her headaches became clear and blackout in her left eye was seen and she was observed with medical treatment. CSF  pressure of her was measured to be 25 cm/ water, so she was diagnosed as pseudotumour cerebri and taken to the operation immediately. On the 3rd day of post-operation, there occurred to be intense stomach ache and abdominal sensitivity of the case. After the scanning of abdominal CT,  7 cm of liquid collection was detected in the shunt distal of liver subcapsular area.

Discussion: Liver pseudocyst should be considered, even if it is a rare complication when back striking abdominal pain and high liver enzymes are seen in patients with shunt dysfunction. USG and abdominal bt tests should be made for these patients. The drainage of the cyst and then the removal of the abdominal catheter should be applied.
Congenital sphenoid wing defect with lateral angular dermoid presenting with CSF leak after orbital surgery
Authors: Mohammad Sarwar , Tripathy Laxminarayan , Ahmed Bari Ejaz
Published: April 2022

Lateral angular dermoid may have associated bony defects which must be recognized before surgery. High-resolution 3-D CT scans and MRIs define these lesions very clearly. Total excision with attention to the bony defect is usually curative. CSF leak from the operative wound at the surgery or in the post-operative period signifies the intracranial connection or dural adhesion unnoticed by the Ophthalmologist before surgery.

Introduction: Traumatic brain injury is a major public health problem worldwide, with higher incidence rates in low- and middle-income countries. In this context, the development of major complications has been evidenced, such as the formation of haemorrhages due to traumatic rupture of a cerebral aneurysm, which may threaten the patient's life and therefore require immediate medical and neurosurgical procedures.
Case: We present the case of a male patient in the fourth decade of life, who presented a closed head trauma with the consequent development of subarachnoid haemorrhage in the territory of the right middle cerebral artery secondary to traumatic aneurysmal rupture
Conclusion: One of the complications that can occur in the context of head trauma is the development of subarachnoid haemorrhage due to traumatic aneurysmal rupture. Despite therapeutic options, these scenarios continue to be a challenge in low- and middle-income countries due to the lack of specialized tools in neurosurgical and neurorehabilitation areas

What matters to me? Photovoice with people living with severe mental illness
Authors:   , Roberts Louise
Published: April 2022

This research aimed to engage with long term services users with severe or serious mental illness whose voices have traditionally been silenced to add to the growing body of knowledge as to how these identified gaps can be addressed. Four participants who attend a day service were issued with cameras and asked to photograph ‘What Matters to Me?’ in their everyday life. The question was a deliberate attempt to usurp the medical dialogue ‘What is a Matter?’ Participants were issued with disposable cameras and the photographs formed the basis for individual interviews. Thematic analysis from a descriptive methodology identified themes which were discussed through the lens of the recovery framework CHIME (Connection, Hope and optimism, Identity Meaning, Empowerment). Findings illustrate that participants identified home, and homemaking, the things they do and the people in their life as what matters. Contrary to much of the literature, participants articulated multiple positive identities viewing an illness identity as only a small part of self. Access to occupations and the importance of narrative and narrative continuity appear to be important aspects of recovery aligning well with the occupational therapy concepts of occupational justice and ‘doing with’.
Political Modernity and the Postcolonial New World Order
Authors: Ndlovu-Gatsheni Sabelo
Published: April 2022

The current world order is organized into invented, self-contained modern nationstates in defiance of realities of globalization, planetary human entanglements and visions of a debordered, denationalised, and deterritorialized, pluriversal world. Modern self-contained nation-states are epistemically products of Euromodernity and ideologically products of modern methodological nationalism. Inevitably, at the centre of Euromodernity has been the unfolding of complex triple processes of nationstate making, colonialism and decolonization as simultaneously co-constituting and contesting phenomena. In the (ex)colonies of Africa, just like in Europe, poets, philosophers and historians actively exercised their minds in epistemic inventions of nationalism and actual writing of nations into concrete existence, with colonialism being subjected to resistance, subversion, critique, and decolonial visions of liberation. This short article calls attention to the crisis of political modernity and the limits of both global and national imaginaries and articulates the agenda of decolonizing the political community.
Now Turning to Our Tomorrows: Decolonial Futures in the Study of Islam
Authors: Bulbulia Aasif
Published: April 2022

The emergence and growth of the decolonial movement in recent years has had a dramatic impact on universities around the world, inspiring new epistemic, political and ontological shifts across a wide range of disciplines. These shifts are broadly described as forming part of ‘the decolonial turn’ (Maldonado-Torres 2007: 261). As new generations of academics in the Study of Islam prepare to further the project of knowledge production in the context of post-Fallist universities, this paper seeks to address the following questions: What might it mean to decolonise the academic Study of Islam? How might decolonisation be consciously foregrounded as a future trajectory in the Study of Islam? After contextualising the academic study of Islam in South Africa and engaging with some of the major themes and concepts of decolonial scholarship, I review contemporary efforts to affect the decolonial turn in the Study of Islam through the initiation of summer schools and conferences. Applying what Sardar (2010) describes as ‘futures studies’ methodology, I propose ways to propel the decolonial turn as anticipatory intervention, based on an attempt to forecast the possible futures that await in the next five to ten years and beyond.

Saving Intentions and Behaviour of International University Students
Authors: Széles Zsuzsanna , Szabó Zoltán
Published: April 2022

Our main goal was to show saving intentions of the young generation especially to examine international university students’ behaviour. Hungary became an attractive destination for foreign students. The number of Stipendium Hungaricum students studying in Hungary reached 7,440 in the academic year of 2018/19. It started with 1,270 students in 2015. Currently (in 2022), 11.000 Stipendium Hungaricum students studying in Hungary and 29 Hungarian higher education institution offering academic programmes for scholarship holders. A questionnaire survey was conducted at Hungarian Universities. We asked students who study in Hungary in international classes of English programmes about their saving behaviour and would like to demonstrate that saving decisions are influenced by tradition, origin, education, country specifications and sociocultural aspects. The primary questions were divided into 3 larger sections including general information, financial background, saving attitudes and saving decision criteria. As the first step we made a regression analysis to determine relations then with multi-variable analysis we can create groups of saving intentions of international students. The results focus on the influencing factors for the young university student generation on how they plan and what their intentions are with their savings in different countries.

Machine Learning (ML) Methods in Assessing the Intensity of Damage Caused by High-Energy Mining Tremors in Traditional Development of LGOM Mining Area
Authors: Witkowski Michał
Published: April 2022

The paper presents a comparative analysis of Machine Learning (ML) research methods allowing to assess the risk of mining damage occurring in traditional masonry buildings located in the mining area of Legnica-Głogów Copper District (LGOM) as a result of intense mining tremors. The database of reports on damage that occurred after the tremors of 20 February 2002, 16 May 2004 and 21 May 2006 formed the basis for the analysis.

Based on these data, classification models were created using the Probabilistic Neural Network (PNN) and the Support Vector Machine (SVM) method.

The results of previous research studies allowed to include structural and geometric features of buildings,as well as protective measures against mining tremors in the model. The probabilistic notation of the model makes it possible to effectively assess the probability of damage in the analysis of large groups of building structures located in the area of paraseismic impacts. The results of the conducted analyses confirm the thesis that the proposed methodology may allow to estimate, with the appropriate probability, the financial outlays that the mining plant should secure for the repair of the expected damage to the traditional development of the LGOM mining area.

In this study, the effects of carbon impurity in the atomic layer deposited-Al2O3 film on the hard X-ray photoelectron spectroscopy (HAXPES) spectra and the electrical properties of metal–insulator–semiconductor (MIS) structure were measured. The carbon concentration in the Al2O3 film was adjusted by varying the deposition conditions (precursor: trimethylaluminum, Al(CH3)3, or dimethylaluminum hydride, Al(CH3)2H, oxidant, and deposition temperature) in the atomic layer deposition process. The HAXPES measurements revealed the correlation between full width at half maximum (FWHM) of Al 1 s and O 1 s spectra and the carbon concentration in the Al2O3 film. Furthermore, the negative charges in the Al2O3 film could change the FWHM, attributed to the carbon impurity. The correlation between the carbon concentration and the electrical characteristics of the Al2O3/AlGaN/GaN MIS structure was analyzed. The interface state density and the effective charge density were dependent on the carbon concentration in the Al2O3 film.

The liquid thermoelectric device (LTE) exhibits a very simple structure that consists of hot/cold electrodes of identical type and a solution with a redox couple. Here, we evaluated the performances of LTE composed of acetone (or acetonitrile) solutions of Fe(ClO4)2/Fe(ClO4)3 against their concentration (m). The electrochemical Seebeck coefficients (α) of organic LTE range from 1.5 to 2.5 mV K−1 and are higher than α (=1.4 mV K−1) of the corresponding aqueous LTE. The dimensionless figure of merit (ZT) of organic LTE is ≈0.015 at maximum and is higher than the maximum ZT (=0.009) of the corresponding aqueous LTE. Thus, the organic LTE is promising as an energy harvesting device.

This study was carried out to evaluate the effect of effluent and influent, from a beverage plant in Lagos state, using haematology, sperm assay, and impact of the physicochemical parameters on mice. The effluent and influent were collected in sterile bottles and were separately administered orally to 5 groups of mice at test concentrations of 6.5%, 12.5%, 25%, 50% and 100%. Mice in each group weighing approximately between 30 and 35 g were given 0.3ml/body weight of mice in each test concentration orally, daily for 21 days. Each treatment group and the control group comprised 3 mice. The resulting data showed that both test samples induced a dose-dependent, statistically significant (p<0.05) increase in the number of sperms with abnormal morphology, haematology, as well as diverse histopathological changes in the liver. The samples were also analyzed for physicochemical properties with standard laboratory techniques. The results obtained revealed that both the effluent and influent samples contain constituents (e.g. Cd, Cr and Ni) in quantities and values that are capable of inducing mutation in the biological system. The interaction of some of these constituents with the genetic material in the differentiating cells during gametogenesis may be responsible for many sperm abnormalities observed in this study. Therefore, this study is important in environmental waste management, and for the assessment of the genotoxic effects of chemicals (both solid and dissolved) in wastewater.
La anticorrupción como corrupción: contradicciones y complejos ideológicos en la política mexicana
Authors: Hodge Bob , Salgado Andrade Eva , Villavicencio Zarza Frida
Published: April 2022

A partir de la perspectiva de la semiótica social y de los estudios del discurso, se examina el papel de las contradicciones en los complejos ideológicos. El estudio de caso es el acto encabezado, en julio de 2016, por el entonces presidente de México, Enrique Peña Nieto, quien, luego de una crítica popular sin precedentes en torno a la corrupción, promulgó el Sistema Nacional Anticorrupción y, simultáneamente, pidió perdón por su actuación. Además de hacer un análisis semiótico del escenario y de los discursos pronunciados durante la ceremonia (a partir de formas macro-sintagmáticas y de un análisis lingüístico puntual), se hizo un análisis multimodal de las primeras planas de ocho diarios mexicanos publicados al día siguiente. Combinamos el concepto del complejo ideológico con el del ver como de Ludwig Wittgenstein (ejemplificado con la figura del pato-conejo), para explicar las contradicciones, exponer las estrategias discursivas e identificar puntos vulnerables en el discurso de la corrupción y la anticorrupción en México.
An Emergency Message and Call System for People with Epilepsy
Authors: R S KRISHNU
Published: April 2022

People with epilepsy (PWE) always worry about
mishaps that can happen to them due to seizure attacks if
someone is not nearby. To overcome this, we have developed a
novel alert system that can help caretakers to reach patients
quickly. The system consists of cloud services that record the
alert signal received from the user. Emergency call is triggered
through a raspberry pi - GSM module interface. A mobile
application was developed to save caretaker contacts and share
location details while an epileptic patient sends out alarm
signals. These location details are conveyed to caretakers as
google map link and address through call and message. By using
cloud services and an emergency call module that can be kept
anywhere with undisturbed network connectivity, the epilepsy
patients with the installed application can initiate alert services
and send distress messages to all caretakers with minimal effort.
The average delays for calls and message received at caretaker's
end from pushing the alarm signal are recorded as 13.6 and 8
seconds respectively.

Choroidal melanoma is a rare tumour, but remains the most common primary intraocular malignancy. It may be discovered incidentally during fundus examination or in the workup of intravitreal haemorrhage, retinal detachment, or even a scleritis or episcleritis-like presentation. We report the case of a 52-year-old man with choroidal melanoma, highlighting the contribution of imaging in the management of this ocular pathology.

Pituitary adenomas emerge from the adenohypophysis and are confined to the region of the sella turcica, however, other sites may be involved as a result of extension infiltration, or ectopic location, the ectopic involvement of the sphenoid is rare. Our case illustrated a woman patient with an ectopic invasive macroprolactinoma diagnosed as a chordoma of the skull base. In Our case, the first histological examination was consistent with a coincidental Intrasellar Chordoma and Pituitary adenoma, Immunostaining was positive for synaptophysin and prolactin with a Ki-67 index of 7%, suggestive of an invasive prolactinoma, in addition to the existence of vacuolated cells with foamy Cytoplasm resembling to hysaliphorous cells suggested the diagnosis of chordoma. However, immunohistochemical study using brachyury and S-100 protein have shown a negative stain. Thus, the diagnosis of chordoma was excluded. Thus, it is particularly important to maintain ectopic pituitary adenomas in sphenoidal or clival locations as the main differential diagnosis of chordoma; because the diagnosis can have significant implications on the management of the tumor, and can give us a golden opportunity for more conservative management (in our example managed with dopamine agonists), if the diagnosis can be made preoperatively rather than retrospectively based on histology.

Introduction: A high pace of urbanization and improvised high-velocity motor vehicles are the leading factors for high energy lower limbs trauma in a middle-income country, Bangladesh resulting in a common compound fracture and dislocation at the level of knee; the proximal and middle third of the leg in the salvageable limb. Among the coverage options, gastrocnemius muscle flap (GMF) and proximally based sural fasciocutaneous flap (PBSFC flap) were used for a long period to meet the good reconstructive goals. Aims and objectives: The study aims to compare between gastrocnemius muscle flaps and proximally based sural artery fasciocutaneous flaps for coverage of soft tissue defect on proximal and middle third of leg with the exposed tibia and/or knee joint in terms of operating time, flap viability and its complications, donor site morbidity, time taken for bone healing. Methods and materials: This study is a retrospective study of 22 cases of those who came with soft tissue defects on knee and proximal and middle third of leg requiring flap coverage in Rajshahi Medical College Hospital from August 2019 to July 2021. Here we harvested medial gastrocnemius muscle flap for coverage of knee and proximal third of the leg and PBSFC flap based on median sural artery was done for the defect on knee to proximal two third of leg. All the donor sites of PBSFC flaps were covered by split thickness skin graft, whereas, in case of GMF, the donor site was tried for direct closure. Results and discussion: 13 GMF and 09 PBSFC flap were done in the study period. All collected data were analyzed in GMF group and PBSFC flap group and made the comparison between two groups by standardized analytic testing tools. Conclusion: In comparisons of two different flaps of the study, none was superior in terms of survivability of the flap, rate wound infection control, bone healing.
