Published: October 2021

Poor cookstove design can harm the user's health and environment. This research aims to obtain an efficient cookstove design, environmentally friendly and operated easily. The cookstove design process using a combination of QFD and TRIZ. QFD able to capture customer needs through a questionnaire and interview. The data collected then processed to build a House of Quality (HoQ), one of the tools in QFD. QFD results in the design parameter of the briquette cookstove, which is incorporated in the concept design. The TRIZ method is utilized to understand the problem that might occur in the concept design and focus on solving the root causes. The next step is a detailed design where the dimensions, combustion chamber capacity, and supporting features are explained. The combination of QFD and TRIZ result in a briquette cookstove concept design which is easy to clean and operate. The combustion system is Top-lit Up-Draft (TLUD). The burning chamber has two air inlets, namely primary and secondary. The primary air inlet supplies the air from the bottom of the burning chamber, partially burns the briquette, and produces flue gas. The secondary air inlet is in the shape of an oval to supply air in the burning chamber's upper part to burn the flue gas completely. A complete combustion process will increase combustion efficiency and reduce emissions. A computational simulation shows the velocity distribution inside the burning chamber.

The spatial distributions of ions (K+, Na+) passed through thin polycrystalline and single-crystalline Al films with the thickness from 180 to 600 Å and critical channeling angles have been studied. The ion energies have been varied within the range E0 = 10-30 keV. It has been shown that an increase in the energy of the primary ion beam leads to a decrease in the width of the maxima of the angular distribution, which is associated with a decrease in the critical channeling angle ψcr. It has been found that the value ψcr does not exceed 4-50 for axial channeling and 9-100 for planar channeling.

Background

Pain is an underappreciated symptom of atopic dermatitis that can affect the health-related quality of life (HRQL) of patients.

Objective

The aim of this study is to understand the effect of pain on patients with atopic dermatitis and their family members and to recognize how this symptom affects HRQL.

Methods

We conducted focus groups and interviews with patients with atopic dermatitis and their family members. Researchers independently coded the transcripts and reached a consensus on the major themes.

Results

A total of 33 adult participants, consisting of 21 patients with atopic dermatitis (median age 47 years, range 22-77) and 12 family members (median age 50, range 22-72), attended either focus groups (23/33, 70%) or
interviews (10/33, 30%), where we assessed their experiences of pain. Four themes emerged in our study. Itchiness and pain can be intertwined: pain was often caused by or otherwise associated with itchiness and could result from open sores and excoriated skin. Characteristics of pain: pain was most often described as burning. Other descriptors included mild, persistent discomfort; stinging; and stabbing. Effects of pain: pain negatively affected various aspects of daily life, including choice of clothing, sleep, social activities, and relationships. The location of painful areas could also limit physical activity, including sex. Pain management: pain from atopic dermatitis could be managed to varying degrees with different over-the-counter and prescription treatments. Systemic agents that cleared the skin also resolved the pain associated with atopic dermatitis.

Conclusions

Pain can be a significant factor in the HRQL of patients with atopic dermatitis and should be considered by clinicians when caring for patients with atopic dermatitis.

Published: October 2021

BACKGROUND

Hip fracture has a severe impact on patients’ quality of life, psychological factors and fitness level. Tele-rehabilitation has emerged in the last years as a promising alternative to conduct the rehabilitation process at home. However, there is no studies testing the effects of tele-rehabilitation interventions for patients with hip fracture on quality of life nor psychological factors, whereas the evidence on fitness level is scarce.

OBJECTIVE

To test the effects of the @ctivehip tele-rehabilitation program on the quality of life, psychological factors and fitness level of patients who had suffered a hip fracture.

METHODS

It is a non-randomized clinical trial including patients with 65 five years old onwards with a hip fracture as well as their family caregivers. The intervention group received a home-based multidisciplinary tele-rehabilitation intervention called @ctivehip lasting 12 weeks and the control group received the traditional care and rehabilitation provided by the Andalusian Public Health Care System. The outcomes measured were the patients’ quality of life through the EuroQol Quality of Life Questionnaire (EQ-5D), physiological factors (anxiety and depression) using the Hospital Anxiety and Depression Scale (HADS), and the fitness level, assessed with the International Fitness Scale (IFIS). Per-protocol (64 participants) and intention-to-treat (71 participants) analyses were performed, being the first one the main analysis.

RESULTS

The quality of life of the tele-rehabilitation group increased, while the control group scored worst at 3-month follow-up (medium effect size: 0.66 SDs; p = 0.006). The tele-rehabilitation group demonstrated a greater decrease than the control group in the total HADS score (medium effect size: -0.50 SDs; p = 0.015). Lastly, the tele-rehabilitation group recovered a fitness level close to the pre-hip fracture in comparison with the control group (small effect size: 0.49 SDs; p = 0.022).

CONCLUSIONS

The @ctivehip tele-rehabilitation program seem to be a promising treatment to improve the quality of life and psychological factors (i.e., anxiety and depression) of older adults after a hip fracture, as well as to recover their previous fitness level.

Quality of Mobile Apps for Care Partners of People With Alzheimer Disease and Related Dementias: Mobile App Rating Scale Evaluation (Preprint)
Authors: Werner Nicole E , Brown Janetta C , Loganathar Priya , Holden Richard J
Published: October 2021

BACKGROUND

Over 11 million care partners in the United States who provide care to people living with Alzheimer disease and related dementias (ADRD) cite persistent and pervasive unmet needs related to their caregiving role. The proliferation of mobile apps for care partners has the potential to meet care partners’ needs, but the quality of apps is unknown.

OBJECTIVE

This study aims to evaluate the quality of publicly available apps for care partners of people living with ADRD and identify design features of low- and high-quality apps to guide future research and user-centered app development.

METHODS

We searched the US Apple App and Google Play stores with the criteria that included apps needed to be available in the US Google Play or Apple App stores, accessible to users out of the box, and primarily intended for use by an informal (family or friend) care partner of a person living with ADRD. We classified and tabulated app functionalities. The included apps were then evaluated using the Mobile App Rating Scale (MARS) using 23 items across 5 dimensions: engagement, functionality, aesthetics, information, and subjective quality. We computed descriptive statistics for each rating. To identify recommendations for future research and app development, we categorized rater comments on score-driving factors for each MARS rating item and what the app could have done to improve the item score.

RESULTS

We evaluated 17 apps. We found that, on average, apps are of minimally acceptable quality. Functionalities supported by apps included education (12/17, 71%), interactive training (3/17, 18%), documentation (3/17, 18%), tracking symptoms (2/17, 12%), care partner community (3/17, 18%), interaction with clinical experts (1/17, 6%), care coordination (2/17, 12%), and activities for the person living with ADRD (2/17, 12%). Of the 17 apps, 8 (47%) had only 1 feature, 6 (35%) had 2 features, and 3 (18%) had 3 features. The MARS quality mean score across apps was 3.08 (SD 0.83) on the 5-point rating scale (1=inadequate to 5=excellent), with apps scoring highest on average on functionality (mean 3.37, SD 0.99) and aesthetics (mean 3.24, SD 0.92) and lowest on average on information (mean 2.95, SD 0.95) and engagement (mean 2.76, SD 0.89). The MARS subjective quality mean score across apps was 2.26 (SD 1.02).

CONCLUSIONS

We identified apps whose mean scores were more than 1 point below minimally acceptable quality, whereas some were more than 1 point above. Many apps had broken features and were rated as below acceptable for engagement and information. Minimally acceptable quality is likely to be insufficient to meet care partner needs. Future research should establish minimum quality standards across dimensions for care partner mobile apps. Design features of high-quality apps identified in this study can provide the foundation for benchmarking these standards.

Several studies found that the probiotic bacterias such as Lactobacillus acidophilus La5 and Bifidobacterium lactis Bb12 could prevent glycemia and control the blood lipid profiles. Currently, a probiotic product such as yogurt is not preferable by some consumers since the taste is sour. Therefore, this study was conducted to develop milkshakes supplemented by probiotics Lactobacillus acidophilus La5 and Bifidobacterium lactis Bb12 which are expected to be more acceptable and have a beneficial effect with the addition of prebiotics and soluble fiber glucomannan. This study aims to determine the effect of synbiotic shakes on fasting blood glucose levels and lipid profiles in hyperglycemia Wistar rat models. The study design was a pre-posttest controlled group with 48 male Wistar rats divided into 8 groups, namely the healthy control group (I); hyperglycemia control group (II); group III that received metformin; group IV that received synbiotic shake with La5 + FOS; group V that received synbiotic shake La5 + inulin; group VI that received synbiotic shake Bb12 + FOS; group VII that received synbiotic shake Bb12 + inulin; and group VIII that received synbiotic shake La5 + Bb12 + FOS. The dose of the intervention was 3.6 ml/day with an intervention duration of 28 days. The results showed that the differences in blood glucose levels were not significant (p> 0.05) except for groups IV and VI that experienced a significant increase (p <0.05). The differences in lipid profiles showed insignificant changes in LDL levels except in groups IV and V, a significant increase in HDL levels (p <0.05) in group V and VI, and insignificant change in triglycerides except in group VI. It can be concluded that the administration of synbiotic shakes with a variety of prebiotics Lactobacillus acidophilus La5 and Bifidobacterium lactis Bb12 for 4 weeks were able to maintain fasting blood glucose levels and lipid profiles in hyperglycemic rats.

Diabetes is a metabolic syndrome characterized by high blood sugar levels or hyperglycemia.Alpha-amylase inhibitors can be used as an antidiabetic that controls postprandial hyperglycemia.Alpha-amylase inhibitors are found in plants as protein and non-protein bioactive content such as in lebuiseed. The purpose of this study was to determine the activity of alpha-amylase inhibition of the fraction ofethanol extract of lebui seed. This research was carried out by extraction of lebui seed and then fractionatedlebui extract to obtain n-hexane fraction (HF), ethyl acetate fraction (EAF), and water fraction (WF). Thefractions then tested to alpha-amylase inhibition activity in vitro by measuring the reducing sugar using3.5-dinitrosalicylic (DNS) reagent. Furthermore, the identification of the bioactive content of each fraction wascarried out using thin layer chromatography. The results of alpha-amylase inhibition activity test showed thatall fractions had the ability to inhibit alpha-amylase. The IC50 value of the n-hexane fraction, ethyl acetatefraction, and water fraction were 173.05 mg/ml, 9.98 mg/ml, and 137.19 mg/ml, respectively. Ethyl acetatefraction has the smallest IC50 value compared to other fractions. Based on the identification of the bioactivecontent, bioactive content that is only found in the ethyl acetate fraction but not in other fractions are tannins.Therefore, the chemical content in lebui seed which acts as an alpha-amylase inhibitor might be tannins.

Wavelet-based Characterization of Seismicity and Geomagnetic Disturbances in the South Sandwich Microplate Area
Authors: Larocca Patricia , Arecco M.A. , Mora M.
Published: October 2021

This paper analyzes geomagnetic disturbances associated with seismic events in the northern transcurrent margin of the South Sandwich microplate and South American plate, with their epicenter at distances within 350 km from King Edward Point geomagnetic observatory on the archipelago of the Georgias del Sur islands.

Geomagnetic field records measured over a one-year period in three observatories of the INTERMAGNET network near the area under study are examined. Anomalous variations in geomagnetic records can be detected within approximately 3 hours before the manifestation of seismic events with a magnitude above 4.4 Mw.

Based on the analysis of the differences in horizontal field components among the observatories and the frequency spectrum of the geomagnetic field observations using the wavelet method, oscillations of several nT can be observed before an event, in addition to magnetic peaks with variable amplitude and duration.

It is worth noting that, during the period of study, no severe ionospheric effects were recorded as this was a phase of low solar activity (solar cycle 24 minimum).

The observation of these potential magnetic precursors suggests that there is a critical preparatory period in a region with geological faults related to the stress generated in the rocks before the built-up energy is released in the hypocenter area, within the lithosphere, which may predict the mechanical motion based on anomalous geomagnetic records.

Published: October 2021

In situ coastal oceanographic and meteorological data were collected on the Mexican Tropical Pacific coast near Barra de Navidad, Jalisco, Mexico during September 2001 from before and after the passing of Hurricane Juliette. When the leading and trailing edges of the hurricane passed through the study area, wind speeds reached 15 m s-1 and caused a significant deepening of the thermocline, mixing of the upper 40 m of the water column, and a rise in sea level of almost 50 cm at the coast, with effects lasting for about 5 days. A decrease in temperature and an increase in salinity occurred in the upper 20 m, with the opposite occurring below 20 m. Although analyses of open ocean responses to hurricanes are widely available from satellite data, in situ coastal water-column and sea-level data are difficult to acquire, yet crucial to inform coastal flooding models and risk assessment studies. This short data set provides a rare opportunity to explore in situ hurricane effects on this understudied coast.

Authors: Prasad Jay Kishor , Dey Riddha , Raghuwanshi Richa
Published: October 2021

Rhizospheric bacteria exhibiting antagonistic effects are a good source for the production of antibiotics. The antibiotics produced are naturally bactericidal or bacteriostatic in nature. In the present investigation thirty-five rhizospheric bacteria were isolated from different soil samples. Agar well diffusion method, streak agar method, disc diffusion method and biochemical tests were performed to screen the ten antibiotic-producing bacteria. Among them, strain JRR34 selected on the basis of primary antagonistic activity was identified as Streptobacillus sp. Media optimisation was done to ensure maximum production of secondary metabolites. Streptobacillus sp. JRR34 showed good inhibitory activity against Escherichia coli, Pseudomonas aeruginosa and Staphylococcus aureus. The ethyl crude extract of Streptobacillus sp. JRR34 rhizobacteria possessing good antagonistic activity against a wide range of pathogenic bacteria can be a vital source of novel antibiotics.

THE LOCATION OF LITERARY THEORY AND SOME OTHER
ARRANGEMENTS
The purpose of this paper is to examine the place of literary theory in Croatian
Literaturwissenschaft, its role in literary studies (especially the study of Croatian
literature), its contribution to the introduction of new research topics, as well as its
encouragement of methodological innovations and critical self-reflection. Focusing
on the discussion of Škreb, Stamać, and Biti, the discussion demonstrates that there
is no “age of innocence” of literary theory and no harmonious complementarity
with literary criticism and literary history. With this in mind and considering the
international context, the well-known story of disciplinary crisis is unmasked as just
another interpretation that can be questioned, and, in the domestic context, as a
form of self-imposed oblivion and nostalgia without any real foundation.

Deep Neural Networks for Human Action Recognition
Authors: Kodulkar Prof. Rajeshwari. J.
Published: October 2021

Abstract: In deep neural networks, human action detection is one of the most demanding and complex tasks. Human gesture recognition is the same as human action recognition. Gesture is defined as a series of bodily motions that communicate a message. Gestures are a more natural and preferable way for humans to engage with computers, thereby bridging the gap between humans and robots. The finest communication platform for the deaf and dumb is human action recognition. We propose in this work to create a system for hand gesture identification that recognizes hand movements, hand characteristics such as peak calculation and angle calculation, and then converts gesture photos into text.

Authors: Birla Ramkrishna
Published: October 2021

Abstract: The demand of concrete for rigid pavement construction is constantly growing. Thus, the extraction of fine aggregate, coarse aggregate and cement from natural resources also increases. The more extraction of these virgin materials from the natural resources enhances the cost of these materials progressively. Therefore, it has severely affected the financial viability of the government for rigid pavement construction. Further, due to urbanization and industrialization the amount of waste material is also increased. This state creating an ecological problem that must be addressed. Therefore, there is an urgent need to preserve natural resources by using recycled or discarded wastes as a construction material. Hence the main objective of this work is to study of utilization of waste material in concrete production for rigid pavement construction. A four stages methodology is proposed in this study. these stages are (I) Determination of quantity of various materials for development of concrete mix (II) Identification of significant waste materials and their properties (III) Prepare concrete mix using replacement of cement, sand, and aggregate by waste material and (IV) Comparative evaluation of different properties of developed concrete mix. This study to check the suitability of waste foundry sand (WFS), granulated blast furnace slag (GBFS), and waste rubber tyre (WRT) as a replacement of fine aggregate, cement, and coarse aggregate respectively. The analysis and results indicated that WFS, GBFS, and WRT can be used as a replacement of fine aggregate, cement, and coarse aggregate respectively. Thus, it is expected that the proposed methodology will be useful for researcher to determination of suitability of different alternative materials for replacement of cement, fine aggregate, and coarse aggregate Keywords: Concrete mix, Waste Material, GGBS, WFS, WRT etc.

Impact Analysis of Auxetic Structures for Military Applications
Authors: De Rohit
Published: October 2021

Abstract: Auxetic structures are special structures which tend to become wider when subjected to longitudinal tension instead of getting compressed, which implies structures having a negative poisson’s ratio. These structures are used in impact pads due to this unique property. In this comparative study were done on different types of materials and structures which are recognized for 3D printing the auxetic structures. The three stages of explicit dynamic analysis involves firstly selecting the most appropriate structures from chiral truss, re-entrant hexagon, arrow head and one non- auxetic structure which is hexagon structure. From this the structure having the least deformation at the impact point is selected which is re-entrant hexagon. Following this, keeping re-entrant hexagon as the structure, the next set of analysis is performed by varying the structure materials. Polycarbonate, polystyrene, polyvinyl chloride and high density polyethylene were studied and the analysis results showed, polyvinyl chloride as the suitable material. Lastly the limiting velocity for the impact is calculated by varying the impact velocity from 800m/s, 1000m/s and 1200m/s beyond which the structure experienced fracture. This study proposes the selection of suitable auxetic structure and material for manufacturing impact pads.

REHABILITATION OF A 60-YEAR-OLD WOMAN’S TIBIAL PLATEAU FRACTURE
Authors: Deshmukh Mithushi
Published: October 2021

Tibial plateau fracture is one of the commonest fractures which leads to the break in the continuity of the upper part of the tibia (shinbone) that involves the knee joint. It involves either lateral tibial condyle or medial tibial condyle or both. This fracture interferes with the normal functioning of the body in day-to-day life. Therefore, physiotherapy rehabilitation after surgery is essential to get back to normal functioning. A 60-year-old female who slipped from a two-wheeler started experiencing severe pain & swelling around the knee joint. Her relatives brought her to Acharya Vinoba Bhave Rural Hospital (AVBRH), Sawangi, Wardha, Maharashtra. X-ray was done and she was diagnosed with lateral tibial condyle fracture (tibial plateau fracture) and then underwent open reduction internal fixation with plate osteosynthesis. Later, she was referred for physiotherapy rehabilitation, which aimed to restore mobility, regain full range of motion, develop muscle strength and build up to weight-bearing. The tibial plateau fracture is a form of fracture with a low occurrence and is a complicated fracture to treat.The above case study concludes that a traditional surgical procedure combined with timely planned physiotherapy rehabilitation contributed to progressive improvement in functional goals, which is an important factor in achieving a good recovery in such post-operative cases.

An acute inflammation associated with lung tissues, alveoli and neighbouring airways caused by streptococcus pneumoniae is referred to as pneumonia. One of the most commonly affecting health problem at all age groups in the world is pneumonia. Antibiotics are the main treatment plan for management of pneumonia, while other treatments are mainly used as supportive care. The purpose of this case report is to evaluate the effect of physiotherapy as an adjuvant for pneumonia management. The patient was a 50 year old male with complaints of dry cough, high grade fever which was associated with chills and breathlessness. He was then diagnosed with pneumonia. Medical management with antibiotics was started along with physiotherapy as an adjuvant. The aim of physiotherapy was to return the patient to his best possible functional recovery. After completion of physiotherapy the patient gained maximum re-expansion of the thorax, had no breathing difficulties, the lungs were clear of sputum and patient was functionally independent. This case report shows how physiotherapy can be used as an adjuvant to rehabilitate a patient diagnosed with pneumonia. This has been demonstrated by increasing the lung expansion, airway clearance and gaining functional independence

Sacralization can be unilateral or bilateral. This disorder arises due to irregularities in the lumbosacral spine segmentation during development. Transverse process of the L5 on one side or both sides is wider than usual and fuses into the sacrum or ilium or both in the sacralization of the fifth lumbar vertebra. Low back pain is the most common symptom in most of the population throughout their lifetime. As low back pain is a leading cause of disability, interfering with quality of life and job outcomes our goal is to assess the association between sacralisation and low back pain. Purpose: To study the relationship between sacralization and low back pain. Because the role of sacralization throughout causing LBP is still controversial. This is the observational study which includes 55 participants who have low back ache. The participants are between the ages 60 to 70 years. The intensity of pain was assessed through NPRS. To assess the relationship between Sacralization and low back pain, all the participants were sent for Xray and the presence of Sacralization was assessed by X-ray. We found that there was a significant relationship between sacralization and low back pain. The patients with sacralization show the high intensity of low back pain. We concluded that Sacralization affects the lumbosacral spine in different ways and result in pain in lower back. And there is significant association of sacralization with low back ache.

Pregnancy termination in the second trimester is riskier than in the first. The primary objective is to create a more effective means of termination while also reducing induction time. To compare the efficacy, safety, and acceptability of intra-cervical foley's catheter with vaginal misoprostol versus vaginal misoprostol for second-trimester pregnancy termination. This clinical study involved 400 pregnant women who were scheduled to have their pregnancy terminated between 13 and 22 weeks of pregnancy for any reason. The enrolled women were divided into two categories: Category I (Misoprostol category): intra-cervical Foley’s catheter inserted with a standard regimen of moistened misoprostol tablets (400 g) 4 hourly inserted vaginally to a maximum of 5 doses; Category II (Combined category): intra-cervical Foley catheter inserted with a standard regimen of moistened misoprostol tablets (400 g) 4 hourly inserted vaginally to a maximum of 5 doses 4 hourly intra-vaginal injections were employed. Misoprostol was retained in the posterior fornix, and the dose was repeated every 4 hours until the catheter was removed, or until a maximum of five doses had been administered. The mean induction to abortion interval in the misoprostol category was 15.38 + 1.25 hours and 8.25 + 2.25 hours in the combination category, which was statistically significant (p= 0.001). The misoprostol category had a 94 percent success rate, while the combined category had a 97 percent success rate. The use of a combined intra-cervical foley's catheter and vaginal misoprostol to end a pregnancy in the second trimester is a novel, safe, effective, and acceptable procedure.
FUNCTIONAL OUTCOME OF PROXIMAL HUMERUS FRACTURES TREATED WITH OPEN REDUCTION AND INTERNAL FIXATION WITH A LOCKING COMPRESSION PLATE: A CROSS SECTIONAL STUDY
Authors: Patil Abhishek
Published: October 2021

Proximal humerus fractures account for about 4% to 5% of all fractures. Following distal forearm fracture, proximal humeral fracture is the second most common upper extremity fracture. Kirschner (K)-Wires, external fixation, tension band wiring, and rush pins, intramedullary nails, ORIF with plates, and shoulder hemiarthroplasty have all been offered as therapeutic options. The purpose of this study was to assess the functional outcome and complication rates following internal fixation of proximal humerus fractures using a locking compression plate. Patients over the age of 18 with closed proximal humerus fractures or open proximal humerus fractures (Gustilo and Anderson type I, Type II) received open reduction and internal fixation with locking compression plate in the current study. The participants in this study were 60 people who had a proximal humerus fracture and were treated with open reduction and a proximal humerus locking compression plate. Patients ranged in age from 20 to 85 years old, with a mean age of 51.14 +/- 17.30 years. The age group 36–55 years (37 percent) was the most prevalent, followed by 56–75 years (30 %). The majority of patients (76.7 %) were men who had been in automobile accidents on the right side (83 %) (63 %). According to the Neer classification, the most prevalent type of fracture was a three-part fracture (53 %). The maximum union time observed in this study was 16 weeks, with a minimum of 10 weeks. The average time to union is 12.52 +/- 1.14 weeks. The mean flexion at the end of six months was 121.660 +/- 19.84. The mean internal rotation was 57.330 +/- 8.48, the mean external rotation was 530 +/- 11.98, and the mean abduction was 1180 +/- 19.36. 75.28 +/- 9.66 [Mean +/- SD] is the Mean Constant score. Pain 14.10, ADL 18.26, range of motion 22.46, and power 20 were the mean scores observed on Constant Score for its various aspects. According to the Constant score, the functional outcome of the 60 patients was as follows: 8 patients had excellent outcomes (13%), 34 patients had good outcomes (56.7%), 16 patients had moderate outcomes (26.7%), and two patients had poor outcomes (26.7%) and (3 %). Internal fixation of proximal humerus fractures with a locking compression plate results in anatomical reduction and secure fixation, resulting in a favorable functional outcome.

Esta investigación presenta una aproximación para determinar la presencia de 131I (isótopo radiactivo usado en el diagnóstico y la terapia metabólica del cáncer de tiroides) en el río Bogotá, cuerpo de agua ubicado en el límite de la capital colombiana. Se tomaron muestras a lo largo de la cuenca media del río, las cuales fueron analizadas por medio de espectrometría de rayos gamma de alta resolución. Se obtuvo una concentración máxima de 16.8 Bq L-1 en el punto denominado Puente de Guadua, cercano a la PTAR El Salitre, seguido por la medición en el punto Gibraltar, con 16.1 Bq L-1. Estos resultados se consideran relevantes por ser cercanos a la concentración máxima establecida para vertimientos en forma líquida a alcantarillas, ríos y otras grandes masas de agua, estipulados en la normativa colombiana, además de que superan el valor de referencia para agua de consumo señalado por la Organización Mundial de la Salud. La presencia de 131I se puede asociar a las actividades del sector médico, como consecuencia del transporte del radioisótopo desde las instalaciones donde se aplica, pasando por las redes de alcantarillado, a la planta de tratamiento de aguas residuales de la ciudad y finalmente al río.

This article describes an example of negligence of drivers transporting passengers and methods of solving it using modern inventions. One of these troubles is driving a car and moving passengers by taxi driver in a tired state. Since not every driver can correctly assess their psycho-physical condition, so to do this, scientists began to create devices for tracking human behavior when he drives vehicle. The purpose of implementing driver fatigue monitoring systems is to ensure road safety and preserve lives and property of citizens. The use of these systems is to facilitate the work of emergency services and taxi company owners, taxi drivers and their passengers. In our article we want to touch on the problem of overwork, specifically taxi drivers, since their work activity is socially significant and non-compliance with the norms of work and rest periods can lead to tragic consequences. Modern taxi drivers often rely on a strong body of car and electronic gadgets in an unexpected situation on the road. Therefore, when driving a car, despite being overworked, they allow themselves to relax beyond the limit and dont react in time if an emergency occurs. We have studied options for implementing driver fatigue monitoring systems and offer to install them on a taxi car.
