The Impact of Connecting Distributed Generation to the Distribution System
Authors: Mgaya E. V. , Müller Z. 
Published: March 2021

This paper deals with the general problem of utilizing of renewable energy sources to generate electric energy. Recent advances in renewable energy power generation technologies, e.g., wind and photovoltaic (PV) technologies, have led to increased interest in the application of these generation devices as distributed generation (DG) units. This paper presents the results of an investigation into possible improvements in the system voltage profile and reduction of system losses when adding wind power DG (wind-DG) to a distribution system. Simulation results are given for a case study, and these show that properly sized wind DGs, placed at carefully selected sites near key distribution substations, could be very effective in improving the distribution system voltage profile and reducing power losses, and hence could improve the effective capacity of the system.

Authors: Brůha O. , Brůha T. , Fořt I. , Jahoda M. 
Published: March 2021

This paper deals with the primary circulation of an agitated liquid in a flat-bottomed cylindrical stirred tank. The study is based on experiments, and the results of the experiments are followed by a theoretical evaluation. The vessel was equipped with four radial baffles and was stirred with a six pitched blade impeller pumping downwards. The experiments were concentrated on the lower part of the vessel, where the space pulsations of the primary loop, originated due to the pumping action of the impeller. This area is considered to be the birthplace of the flow macroinstabilities in the system – a phenomenon which has been studied and described by several authors. The flow was observed in a vertical plane passing through the axis of the vessel. The flow patterns of the agitated liquid were visualized by means of Al micro particles illuminated by a vertical light knife and scanned by a digital camera. The experimental conditions corresponded to the turbulent regime of agitated liquid flow.It was found that the primary circulation loop is elliptical in shape. The main diameter of the primary loop is not constant. It increases in time and after reaching a certain value the loop disintegrates and collapses. This process is characterized by a certain periodicity and its period proved to be correlated to the occurrence of flow macroinstability. The instability of the loop can be explained by a dissipated energy balance. When the primary loop reaches the level of disintegration, the whole impeller power output is dissipated and under this condition any flow alteration requiring additional energy, even a very small vortex separation, causes the loop to collapse.

Superior Colliculus Controls the Activity of the Rostromedial Tegmental Nuclei in an Asymmetrical Manner
Authors: Pradel Kamil , Drwiȩga Gniewosz , Błasiak Tomasz 
Published: March 2021

Dopaminergic (DA) neurons of the midbrain are involved in controlling orienting and approach of animals toward relevant external stimuli. The firing of DA neurons is regulated by many brain structures; however, the sensory input is provided predominantly by the ipsilateral superior colliculus (SC). It is suggested that SC also innervates the contralateral rostromedial tegmental nucleus (RMTg)—the main inhibitory input to DA neurons. Therefore, this study aimed to describe the physiology and anatomy of the SC–RMTg pathway. To investigate the anatomic connections within the circuit of interest, anterograde, retrograde, and transsynaptic tract-tracing studies were performed on male Sprague Dawley rats. We have observed that RMTg is monosynaptically innervated predominantly by the lateral parts of the intermediate layer of the contralateral SC. To study the physiology of this neuronal pathway, we conductedin vivoelectrophysiological experiments combined with optogenetics; the activity of RMTg neurons was recorded using silicon probes, while either contralateral or ipsilateral SC was optogenetically stimulated. Obtained results revealed that activation of the contralateral SC excites the majority of RMTg neurons, while stimulation of the ipsilateral SC evokes similar proportions of excitatory or inhibitory responses. Consequently, single-unit recordings showed that the activation of RMTg neurons innervated by the contralateral SC, or stimulation of contralateral SC-originating axon terminals within the RMTg, inhibits midbrain DA neurons. Together, the anatomy and physiology of the discovered brain circuit suggest its involvement in the orienting and motivation-driven locomotion of animals based on the direction of external sensory stimuli.SIGNIFICANCE STATEMENTDopaminergic neurons are the target of predominantly ipsilateral, excitatory innervation originating from the superior colliculus. However, we demonstrate in our study that SC inhibits the activity of dopaminergic neurons on the contralateral side of the brain via the rostromedial tegmental nucleus. In this way, sensory information received by the animal from one hemifield could induce opposite effects on both sides of the dopaminergic system. It was shown that the side to which an animal directs its behavior is a manifestation of asymmetry in dopamine release between left and right striatum. Animals tend to move oppositely to the hemisphere with higher striatal dopamine concentration. This explains how the above-described circuit might guide the behavior of animals according to the direction of incoming sensory stimuli.
The Transition Zone Protein AHI1 Regulates Neuronal Ciliary Trafficking of MCHR1 and Its Downstream Signaling Pathway
Authors: Hsiao Yi-Chun , Muñoz-Estrada Jesús , Tuz Karina , Ferland Russell J. 
Published: March 2021

The Abelson-helper integration site 1 (AHI1) gene encodes for a ciliary transition zone localizing protein that when mutated causes the human ciliopathy, Joubert syndrome. We prepared and examined neuronal cultures derived from male and female embryonicAhi1+/+andAhi1–/–mice (littermates) and found that the distribution of ciliary melanin-concentrating hormone receptor-1 (MchR1) was significantly reduced inAhi1–/–neurons; however, the total and surface expression of MchR1 onAhi1–/–neurons was similar to controls (Ahi1+/+). This indicates that a pathway for MchR1 trafficking to the surface plasma membrane is intact, but the process of targeting MchR1 into cilia is impaired in Ahi1-deficient mouse neurons, indicating a role for Ahi1 in localizing MchR1 to the cilium. MouseAhi1–/–neurons that fail to accumulate MchR1 in the ciliary membrane have significant decreases in two downstream MchR1 signaling pathways [cAMP and extracellular signal-regulated kinase (Erk)] on MCH stimulation. These results suggest that the ciliary localization of MchR1 is necessary and critical for MchR1 signaling, with Ahi1 participating in regulating MchR1 localization to cilia, and further supporting cilia as critical signaling centers in neurons.SIGNIFICANCE STATEMENTOur work here demonstrates that neuronal primary cilia are powerful and focused signaling centers for the G-protein-coupled receptor (GPCR), melanin-concentrating hormone receptor-1 (MCHR1), with a role for the ciliary transition zone protein, Abelson-helper integration site 1 (AHI1), in mediating ciliary trafficking of MCHR1. Moreover, our manuscript further expands the repertoire of cilia functions on neurons, a cell type that has not received significant attention in the cilia field. Lastly, our work demonstrates the significant influence of ciliary GPCR signaling in the overall signaling of neurons.

Carbapenemase-producing Enterobacterales (CPE) infections have increased in recent years. Colombia has become an endemic country for this group of microorganisms, and the infections they cause have a serious impact in terms of morbidity and mortality. The early identification of CPE carriers who are admitted to health care centers as patients is necessary to implement adequate isolation and infection control measures to limit the spread of this type of microorganisms in hospitals. Furthermore, treating these infections is a challenging task due to the limited therapeutic alternatives available and the fact that there are only a few studies proving their effectiveness in this setting. Therefore, the objective of the present work is to develop a clinical practice guideline (CPG) for the screening of patients at risk of CPE colonization and the treatment of inpatients with suspected or confirmed infections caused by this type of bacteria through a CPG adaptation process based on the ADAPTE methodology. With this purpose in mind, evidence-informed recommendations for the screening and timely identification of CPE carriers admitted to hospitals are made, as well as for the adequate pharmacological treatment of CPE infections in this context. Taking this into account, the objective of this work is to develop a clinical practice guideline (CPG) for the screening of patients at risk of CPE colonization and for the management of inpatients with suspected or confirmed infections caused by this type of enterobacteriaceae by means of a CPGs adaptation process based on the ADAPTE methodology. With this purpose in mind, evidence-informed recommendations for the screening and timely identification of CPE carriers admitted to hospitals are made, as well as for the adequate pharmacological management of CPE infections in this setting.
Pericardial effusion associated with DRESS syndrome. Case report
Authors: Román-Chica Laura María , Díaz-Duarte Angela María 
Published: March 2021

Introduction: The DRESS (drug reaction with eosinophilia and systemic symptoms) syndrome is a rare but serious and potentially lethal occurrence of a set of signs and symptoms associated with the use certain types of drugs. This syndrome is characterized by a heterogeneous clinical manifestation that, in many cases, results in multisystemic involvement.
Case presentation: A 24-year-old man from Calarcá, Colombia, visited the emergency department of the local hospital due to a three-day history of unquantified intermittent fever associated with asthenia, adynamia, anorexia, headache, myalgia, odynophagia, and upper abdominal pain. Due to his condition and based on laboratory findings, he was referred to the Clínica Central del Quindío. The patient, 20 days before the initial assessment, had been prescribed a pharmacological treatment with non-steroidal anti-inflammatory drugs and phenytoin due to a severe cranioencephalic trauma; he also presented with generalized skin rash, elevated transaminases, and moderate eosinophilia. Complementary studies reported mild pericardial effusion, so DRESS syndrome was suspected, and corticosteroid therapy was started, achieving the complete remission of the syndrome.
Conclusion: Although the DRESS syndrome has a low incidence, it should always be suspected, especially in patients with cardiac and pericardial involvement. In this case, pericardial involvement was evident, demonstrating that individuals with this syndrome may present with rare symptoms that have a serious impact on their health, as they may significantly increase adverse outcomes and mortality risk.

Authors: Sakshi Bangia Ritika Thusoo, Sheilza Jain, 
Published: March 2021

The advancement in the field of aerial robotics and control engineering has created many opportunities for the utilization of Unmanned Aerial Vehicles (UAVs). Applications of UAVs from precision agriculture to delivering medicines and products at our doorsteps cannot be ignored. Quadrotors are the widely studied as sub-category of the rotor-type UAVs. Their ability to hover, vertical take-off and landing along with their small size and simple design make them suitable for many real-life applications like medicine delivery in containment zones struck with COVID-19. But under actuation caused due to four rotors to control six inputs creates instability in their flight. In this paper, Quadrotors and various Quadrotor applications are discussed. The various modeling and control techniques are discussed. Controlling techniques like LQR, LQG, PID and robust control is implemented for position, attitude and altitude control. Results for Proportional Integral and Derivative (PID) and Model Reference Adaptive Control (MRAC) of model generated using force-moment mathematical model are analyzed and compared using MATLAB Simulink. These control techniques are implemented for position, attitude and altitude control. In this paper, it has been concluded that MRAC performs better as compared to PID controller for position, attitude and Altitude control of Quadrotor.

THE ROLE OF VIDEO CONFERENCING IN FOREIGN LANGUAGE LEARNING AMONG YOUNG STUDENTS
Authors: Medic Branko 
Published: March 2021

During the coronavirus pandemic research on video conferencing effects on young language learners is more than ever relevant. During the sharp transition, educators need to fully understand the benefits and possible pitfalls of video conferencing, but also overcome resistance to change through knowledge. As author Philip Pullman rightly points out, “You cannot change what you are, only what you do.” This article summarised key research and provided evidence for and against the use of video conferencing in foreign language education. Thus, it gives food for thought and reflection, as well as directions for possible interventions. However, the research was limited in terms of time and available literature, and the topic certainly requires more attention. In future, it is recommended to further research the use of multimodal interactions (sound, audio, text) in video conferencing, as well as coping strategies for dealing with the lack of interaction in the video conferencing-enabled classroom.
ANALYSIS OF SENSORY MARKETING ON CONSUMERS AT RETAIL STORES
Authors: Shweta Roy Himanshu Gulati, 
Published: March 2021

In order to be forever etched in the minds of customers, Retail Store owners use Sensory Marketing techniques to provide a holistic experience to them at stores. How much a product or service is perceived by a customer is referred to as a sensory experience. The experience of a customer in a store has a huge impact on their buying decision and the image that the customer has of the company. In order to provide an experience that stays with the customers, retailers use techniques to influence the sensory experience of customers in a store. These experiences are results of external stimuli to our senses of touch, taste, sight, smell and hearing. This paper aims to study the factors that impact the holistic experience of consumers at a store. It aims to understand which sensory experience is of utmost importance to a customer in terms of providing a holistic sensory experience. An effort is also done to identify and assess the holistic sensory experience of Indian retail industry customers, as well as to determine their understanding of sensory marketing strategies used in such retail shops.
IMPACT OF THE VISUAL DESIGN LANGUAGE OF SOCIAL MEDIA ADVERTISEMENTS ON CONSUMER PERCEPTIONS
Authors: Kaushik Vishal 
Published: March 2021

There are plenty of ways to promote or sell a product, service, idea or an event, and only recently, there has been a surge in research that proves that visual aesthetics and design play a vital role in making an advertisement appealing or attractive to the consumer to buy or use.
The key purpose of this paper is to establish the principles or a framework that an advertiser keeps in mind while trying to appeal to the consumer’s perception of a brand offering. It shows how important visual design and imageries are in impacting the minds of the consumer. The people in the market are smart and they are able to identify the elements and traits in a design that makes it more appealing to them. And therefore, if a product’s communication appeals to its consumers, they are bound to purchase the said offering. Hence this study becomes very important for the brands, advertisers and the marketing industry as it tells them what makes their communications more attractive to their customers. Thus, the paper investigates how a customer’s opinion impacts their perception about the visual designs presented in the study.
The study allows the people of the sample group to pick their favoured design out of the options given based on a particular principal of design. The sample group is henceforth tested on various other principles of design theory and hence we establish the level of understanding the group possesses towards design and aesthetics of any product.
The findings from empirical analysis indicates that visual designs of various ads tend to play a vital role when it comes to swaying the perception of consumers.
In was particularly observed in research that perceptive “matching” of target segment needs (desiring product being presented in a visually pleasing manner) and visual properties utilized in adverts (verbal or visual predominately) seems to be vital.
The utilization of images/visual design has an impact on the consumer’s perception as it is able to uplift recall value, motivate their attitude toward company’s promoted objects, and therefore harness their psychological intentions. Visual communication grabs attention as adverts have become so meta and complex in its efforts to use design & aesthetics to persuade customers and seize their focus.
