Development of an Irrigation and Drainage Monitoring and Management Software for Maintaining the Drainage Ratio in Hydroponics

A decade-long journey shed light on chemical composition and field determination of acid mine drainage in Brazil.

Regular monitoring of Acid Mine Drainage (AMD) is essential for understanding its extent and impact on water resources. Traditional manual sampling methods have limitations, such as limited representativeness and delayed lab analysis. High-frequency monitoring offers an alternative, enabling real-time analysis of AMD fluctuations and determination of constituents in the field. This study assessed a decade-long environmental monitoring database from watersheds impacted by coal mining in Brazil to analyze the relationships between physical properties and constituents from different water sources affected by AMD. Samples were grouped into four categories based on location and contamination levels. Results revealed that water samples from the two groups not affected by AMD exhibited near-neutral pH, low metal and sulfate concentrations, and a large portion of samples below the quantification limit for Mn and Al. In contrast, samples from groups affected by AMD displayed high metal and sulfate concentrations and acidic pH, with the highest contamination observed in the underground mine discharges group (AMD UMD). Spearman correlation analyzes between field (pH and electrical conductivity (EC)) and lab (SO42-, Fe, Mn, and Al) parameters showed no significant correlations in non-AMD-affected groups, but significant correlations in AMD-affected groups, particularly the Streams group. A regression model between sulfate and EC was identified as the best predictor for AMD, enabling continuous, low-cost monitoring of contaminated streams and providing insight into previously unobserved AMD processes, such as variations in contamination during storm events and river flushing.

Benefits of using digital thoracic drainage systems for post-operative treatment in pediatric populations: personal experience and review of literature.

The digital chest drainage monitoring system (Medela Thopaz+), unlike analogical systems, reliably regulates the pressure applied to the patient's chest and digitally and silently monitors critical therapeutic indicators (volume of fluid and/or drained air). Its use in adulthood has been widely described, but there is still little experience in the pediatric field. The aim of this study is to test this new device in the pediatric population. We conducted a retrospective study of 160 patients undergoing chest surgery at our Hospital. These patients were divided into 82 treated with the Thopaz system in the period from January 2021 to April 2023 and 78 in whom Pleurevac, had been used in the time period from January 2020 to April 2023. The average age of patients was 10.45 years (range: 3.1-17.2) for the Thopaz Group and 10.71 years for Pleurevac Group. The groups were homogeneus also by weight and type of intervention. The device was held in place for 10.64 days (mean) for Thopaz Group, compared to 16.87 days (mean) for Pleurevac Group (p < 0.05). The median number of postoperative x-rays before the closure of the chest tube was 4.29 in the digital drainage group compared to 8.41 in the traditional draining group (p < 0.05). The digital chest monitoring device provides objective measurement, allows for rapid patient mobilization (with good pain control and increased compliance). In addition, the use of Thopaz in the paediatric population seems to be safe (there is no statistically significant difference in terms of complications such as prolonged air leaks and pneumothorax after the chest tube closure) and potentially beneficial.

Manhole Detection and Monitoring System using IoT

Nowadays, manholes and its maintenance are the main problem in the metropolitan smart cities. A drainage monitoring system plays a significant role in keeping the towns and cities healthy and clean. The major challenge is to further investigate the condition of manholes on the road. In observation, most of the manhole’s lids were not in the settled emplacement and are in damaged condition. Because of these damaged manholes, there are chances of occurrence of accidents on the road. These damaged manholes will be hazardous to personal safety. If the sewage maintenance is not proper, ground water gets contaminated causing infectious diseases. Blockages in drains during monsoon season causes problems in the routine of the public. Hence, there should be a facility in which it alerts the officials about blockages in sewers, their exact location and about the gas explosion, increase in the water level and temperature level. The goal of this project is to create an effective accident-avoidance system by avoiding open manholes in large cities. This system includes an array of sensors for complete monitoring of the manhole cover such that many accidents can be prevented. This system reduces the work of manpower and increases the safety and speed of work. The working and implementation of this project will be very useful to take necessary actions and maintain the regularity of the municipal society

This system can monitor the status of the street lights and manholes in real time. It can also notify the officials through a text message. KEYWORDS: ARDUINO, IOT, STREET LIGHT MANAGEMENT, MANHOLES MONITORING.

Chyle Leak After Axillary Node Clearance in Breast Cancer Surgery—A Rare Complication and a Proposed Management Strategy from the British and Italian Experience

Chyle leak after axillary surgery is a rare complication that lacks consensus and management guidelines. This study aimed to present the experiences of two centers in chyle leak management after axillary node clearance for breast cancer. Furthermore the authors provide a review of its pathophysiology and clinical diagnostic methods. They compare approaches for management of the axilla with those for other locations. A multicentre case series descriptive analysis of chyle leak after breast cancer axillary node clearance between 1 January 2013 and 31 May 2020 was performed. The center in the United Kingdom and the center in Italy performed 655 and 4969 axillary node clearances, respectively. Four patients experienced chyle leaks. All the leaks had left-sided surgery (3 patients had level 3 clearances with mastectomy and implant-based breast reconstructions; 1 patient had level 2 clearance with therapeutic mammoplasty). All the leaks appeared within 3 days after surgery. Leak duration was between 11 and 29 days. The maximum daily output was 600 mL. All the leaks were treated conservatively with nutritional team support together with close drainage monitoring. The management strategy included a low-fat diet, a high-protein diet, total parenteral nutrition, and medium chain triglyceride supplements, as well as other elements. No negative effects on oncoplastic and reconstructive breast surgery wound-healing and no delays in adjuvant treatment were observed. The incidence of chyle leak after breast cancer axillary node clearance was 0.07%. Early diagnosis and close monitoring together with conservative management involving nutritional team support can result in successful treatment of chyle leak without negative sequalae of breast cancer oncologic treatment.

Concurrent Peritonsillar Abscess and Uvular Hydrops in a Pediatric Patient

Although peritonsillar abscesses (PTAs) are a common presentation in pediatric patients, there are very few reports on a pediatric patient with both a PTA and uvular hydrops. Our patient presented to the emergency room after being unsuccessfully treated for pharyngitis, with odynophagia, dyspnea, muffled voice, drooling, and trismus. On physical examination, we observed a PTA as well as an edematous and erythematous uvula. Following the standard of care, the patient underwent a needle aspiration in the emergency department and subsequently was admitted overnight for observation. The patient had great symptom relief after undergoing drainage of his PTA and was discharged the next morning with symptom resolution of his dyspnea and odynophagia. We recommend drainage and close monitoring for airway compromise as an appropriate treatment course for PTAs and concurrent uvular hydrops.

In this project, An Advanced Underground Drainage Monitoring And Automatic Rescue System using Internet of Things is proposed to protect the sanitation workers form health issues. In India sewage can be cleaned from manholes and drains are a difficult and risky task for anyone, but these people/workers are forced to do these jobs just to earn for their family economy. In order to overcome this issues, a new device is proposed to monitor the human health while entering into the sewage and provide the health parameters in the real time to the officials outside or the control room. Particularly, blood pressure of sanitation workers and toxic gas level of drainage is monitored using this new proposed rescue system. The main component of this system is Arduino controller. There are three types of sensors such as Toxic gas sensor, Methane gas sensor and Ultrasonic sensor used for the proposed system. Water level indicator is used when drainage is full to find from ultrasonic sensor, SMS will be send through GSM technology. Methane Gas and Toxic gas sensor level is high, Buzzer will be ON at the same time location will be share automatically with the help of GPS. The received sensor details display on LCD at receiver with help of GSM. The performance of proposed system is compared with other existing system and shown to be more effective in terms of protect the sanitation workers from health issues.

The effects of sorbing and non-sorbing gases on ultrasonic wave propagation in fractured coal

The acoustic wave propagation in geomaterials at different frequencies (ultrasonic, sonic, and seismic) has been extensively studied in the past to relate geomaterials' physical parameters to wave features. The ultrasonic analysis, commonly used for laboratory scale measurements, has been mainly employed to investigate wave propagation in non-sorbing rocks. The ultrasonic response of gas sorptive sediments particularly coal and its involved physical processes have however attracted limited attention to date. In this study, we use a combination of ultrasonic transmission and X-ray micro-computed tomography (XRCT) along with numerical simulation to investigate the mechanisms influencing the wave propagation in fractured coals. The simultaneous ultrasonic transmission and XRCT imaging are performed on stressed coal specimens saturated with non-sorbing (He) and sorbing (CO2) gases at different pore pressures. We further simulate ultrasonic wave propagation on segmented XRCT images and compare the numerical results with those of the experiments. A further numerical simulation is conducted on synthetic coal geometries to investigate the cleat and matrix property variation on wave propagation. Analysis of experimental and numerical results reveals that the closure of fractures (cleats) by matrix swelling (induced by CO2 adsorption) predominantly controls the change in wave velocities and the effect of change in matrix properties by gas adsorption on wave propagation is rather trivial. The numerical analysis on synthetic coal geometries further confirms that the effect of changes in coal matrix properties (density and stiffness) by gas adsorption on wave velocity is insignificant. In addition, the results show that the fracture aperture and density influence the wave velocities more significantly at low fracture porosity indicating that wave velocities are more sensitive to fractures when swelling is present (reduction in fracture porosity). These observations have significant implications in the characterization and monitoring of coal seam gas production and gas drainage.

Tile drainage monitoring in agricultural fields with an unmanned aerial system

In Russia, the volume of restoration and maintenance work of drainage reclamation systems has significantly decreased, the number of trained reclamation specialists has decreased, most of the objects need reconstruction, and the documentation and schemes of pipes and channels of drainage systems have been lost. Accordingly, the development of agricultural drainage reclamation will require large amounts of financial and labor costs. The aim of the work is to present an alternative approach to assessing the status of these systems for making management decisions using an unmanned aerial system (UAS), which allows you to quickly obtain high quality aerial photographs (2-7 cm/pixel) of an agricultural area up to 50 hectares in one flight. In addition to the unmanned aerial vehicle, the UAS also includes an onboard complex, a payload and a ground control station. The flight group carries out all stages of data acquisition and preprocessing in an automated mode using specialized software. In the course of the experimental studies, the main elements of the considered approach to monitoring drainage systems are highlighted: the period of aerial photography, determination of the pipes and canals schemes, determination of waterlogging zones on agricultural areas and breakdowns of a reclamation system, monitoring in dynamics. As a result, when solving the problem of monitoring drainage reclamation systems, the use of UAS seems to be a relevant and promising approach, which makes it possible to assess the object status promptly.

Stroke, spinal cord ischemia and upper limb ischemia in patients undergoing TEVAR with coverage of the left subclavian artery: a case series study

BackgroundWe performed routine spinal fluid drainage for patients who underwent TEVAR for thoracic aortic pathology together with left subclavian artery coverage, which was needed for achievement of a safe proximal sealing zone. We assessed the occurrence of spinal cord ischemia as well the rate of occurrence of other complications such as stroke, and upper limb ischemia.ResultsThis was a case series study done between July 2014 and April 2020, in them all the left subclavian artery was covered to ensure a proximal safe seal zone. Routine spinal fluid drainage was done, keeping the spinal fluid pressure < 10–15 mmHg with catheter in place for 48 h. Data was obtained from twenty-three patients who underwent TEVAR for thoracic aortic dissection (73.91%), thoracic aortic aneurysm (21.74%), or ulcer (4.35%). Planning was based upon multi-slice computed tomographic angiography and covering the left subclavian was mandatory to achieve a proximal sealing zone. Technical success was achieved in 100% of cases. 4.35% of patients had three endograft, 56.52% had two endografts, 39.13% had one endograft. All patients lost their radial pulsations immediately after implantation, 8.70% developed post implantation syndrome(fever) that was managed conservatively, 4.35% developed stroke related to the anterior circulation, 4.35% developed signs of spinal cord ischemia. During the follow up, one patient died within 6 h after the procedure due to extensive myocardial infarction (patient was scheduled for CABG after our procedure). 17.40% developed upper limb symptoms that were tolerable and were managed conservatively.ConclusionBy adopting routine spinal cord drainage and pressure monitoring, we can consider not to revascularize the left subclavian artery prior to TEVAR if it will be covered.

Ovarian Hyperstimulation: Diagnosis, Prevention, and Management.

Ovarian hyperstimulation syndrome (OHSS) is a severe complication of controlled ovarian stimulation (COS). Pathogenesis of the disease is based on massive transudation of protein-rich fluid from the vascular compartment into the peritoneal, pleural and pericardial spaces, with a variable picture of clinical manifestations depending on its severity. Nowadays OHSS can easily be avoided by several prevention methods, ranging from identification of high-risk patients, choice of a correct protocol stimulation, trigger with gonadotropin-releasing hormone (GnRH) agonists or, finally, the freeze-all strategy. When OHSS occurs, it can usually be managed as outpatient care. Only if severe/critical cases are diagnosed hospitalization is necessary for appropriate rehydration, monitoring of fluid balance and eventual drainage of ascitic fluid. One of the most dangerous complications of OHSS is venous thromboembolism (VTE). Thromboprophylaxis has shown to be cost effective and widely used, while there are controversies regarding the usage of low dose aspirin (LDA) as a preventive measure.

Determination of Unsaturated Hydraulic Properties of Seepage Flow Process in Municipal Solid Waste

The unsaturated hydraulic characteristics of waste soil are an essential basis for predicting and evaluating leachate migration and distribution in landfills. The saturated water content and permeability coefficient were measured, and a multi-step drainage monitoring experiment was conducted indoors at different dry densities, particle sizes, and degradation ages. Single and dual permeability models were adopted to determine the unsaturated hydraulic characteristic parameters of waste. Results show that dry density and particle size are the key factors affecting the saturated water content and permeability of waste. A single degradation age has little effect on it. Respectively, the saturated water content has a linear relationship with dry density, and permeability has an exponential relationship with dry density under limited experimental data. The overflow numerical inversion method can accurately obtain the unsaturated hydraulic characteristic parameters of wastes and summarizes the values of the unsaturated hydraulic characteristic parameters of wastes with different attributes in the literature and the results of this study. The dual-permeability model performed significantly better than the single-permeability model for water movement, suggesting that a dual-domain description is required for water flow in landfills.

Seismic time-lapse monitoring of gas drainage in an underground coal working face

Gas drainage is a popular method used for preventing gas outbursts in coal seams. However, quantitative assessment of the drainage remains a challenging task. In this study, we conducted a seismic time-lapse monitoring study at the No. 15110 working face in the Sijiazhuang coal mine to evaluate the effectiveness of the gas drainage process. The result reveals that there is a remarkable difference in frequency bands and computed tomography (CT) image, inverted from the attenuation coefficients of the recorded channel waves, before and after the gas drainage. In the thick mylonitic coal zone, gas drainage operation generally decreases the wave frequency and wave attenuation. The comparable roof refractions from the monitored seismogram and CT-inverted velocity distributions demonstrate that changes in the coalbed roof during the gas drainage are minor. The attenuation differences are attributed mainly to the stress-relieving effects of the thick mylonitic coal zone. This observation is supported by the forward modeling of the channel waves. Time-lapse seismic monitoring employed in this study provides a useful tool for monitoring the impact of gas drainage on a coal working face, including its roof, for any coal mine with restively simple geological structures.

UAS-Based Hyperspectral Environmental Monitoring of Acid Mine Drainage Affected Waters

The exposure of metal sulfides to air or water, either produced naturally or due to mining activities, can result in environmentally damaging acid mine drainage (AMD). This needs to be accurately monitored and remediated. In this study, we apply high-resolution unmanned aerial system (UAS)-based hyperspectral mapping tools to provide a useful, fast, and non-invasive method for the monitoring aspect. Specifically, we propose a machine learning framework to integrate visible to near-infrared (VNIR) hyperspectral data with physicochemical field data from water and sediments, together with laboratory analyses to precisely map the extent of acid mine drainage in the Tintillo River (Spain). This river collects the drainage from the western part of the Rio Tinto massive sulfide deposit and discharges large quantities of acidic water with significant amounts of dissolved metals (Fe, Al, Cu, Zn, amongst others) into the Odiel River. At the confluence of these rivers, different geochemical and mineralogical processes occur due to the interaction of very acidic water (pH 2.5–3.0) with neutral water (pH 7.0–8.0). This complexity makes the area an ideal test site for the application of hyperspectral mapping to characterize both rivers and better evaluate contaminated water bodies with remote sensing imagery. Our approach makes use of a supervised random forest (RF) regression for the extended mapping of water properties, using the samples collected in the field as ground-truth and training data. The resulting maps successfully estimate the concentration of dissolved metals and related physicochemical properties in water, and trace associated iron species (e.g., jarosite, goethite) within sediments. These results highlight the capabilities of UAS-based hyperspectral data to monitor water bodies in mining environments, by mapping their hydrogeochemical properties, using few field samples. Hence, we have demonstrated that our workflow allows the rapid discrimination and mapping of AMD contamination in water, providing an essential basis for monitoring and subsequent remediation.

IoT based smart drainage monitoring and cleaning system for solid waste materials

Water is the basic requirement for the survival of life on earth. The water is mainly used for cooking, cleaning and drinking purpose. In which more solid ingredients along with water also reaches. The disposals of sewages are still a challenging task in this modern world. The main purpose of smart drainage system is collecting the solid waste which includes bottles, polythene and transport to the disposal area. Otherwise the solid waste will block the drainage system. To avoid such situation, the solid waste are need to be collected and disposed it into collecting bin. The proposed system will automatically cleans the water in the drainage system with the help of drive system controlled by Arduino and the mechanical setup which are driven by servo motor collect the solid waste and dispose it in waste bucket to avoid drainage block. It reduces the cost of manual labour as well as reduces the threat to human life.

Complications of ventral hernia alloplasty: treatment and prevention

Background. Postoperative ventral hernias (PVH) account for 22.4-25.0 % of the total number of abdominal hernias. Complications of PVH alloplasty are divided into general (abdominal compartment syndrome (ACS), acute intestinal obstruction, pneumonia, pulmonary embolism) and local (seroma, hematoma, suppuration, marginal skin defect, calcification, fistula).&#x0D; Objective. To describe the treatment and prevention of complications of PVH alloplasty.&#x0D; Materials and methods. Analysis of literature data on this topic.&#x0D; Results and discussion. ACS occurs after alloplasty of giant PVG as a result of a steady increase in intra-abdominal pressure (IAP) &gt;12 mm Hg within 6-12 hours after surgery. ACS is caused by the excessive tension of the supporting structures of the abdominal wall and a decrease in the volume of the abdominal cavity. The growth of IAP leads to compression of large vessels, kidneys, increased intrathoracic pressure with the development of heart and lung failure, so during and after surgery it is necessary to monitor this parameter with the help of Foley catheter. Prevention of ACS is carried out by the optimal choice of the method of compartment separation. In the postoperative period, anesthesia (paracetamol – Infulgan, “Yuria-Pharm”), oxygen therapy, abdominal bandaging, nonsteroidal anti-inflammatory drugs (NSAID), medications for the correction of water-electrolyte metabolism (Reosorbilact, “Yuria-Pharm”) are prescribed. Among wound complications seroma is the most common (30.8-60.4 %). Methods of its treatment include vacuum drainage, puncture, antibiotics and NSAID. In presence of localized limited infection in the tissues of the abdominal wall around the mesh, excision of the mesh area with granulomas within healthy tissues, washing of the wound with Dekasan solution (“Yuria-Pharm”) and defect plastics are indicated. Antibiotic therapy is performed according to sensitivity. In the presence of a widespread infection in the tissues of the abdominal wall along the perimeter of the mesh, its explantation is indicated. Repeated direct alloplasty in such cases is contraindicated. Prevention of wound complications includes antibiotic prophylaxis (ceftriaxone 2 g), adequate choice of alloplasty, washing of the surgical wound with Dekasan solution at the different stages of surgery, vacuum drainage and ultrasound monitoring.&#x0D; Conclusions. 1. Optimization of prevention of wound complications during non-purulent surgical interventions is reached by washing of the surgical wound with Dekasan solution. 2. Optimization of prevention of wound complications during conditionally clean (non-purulent) surgical interventions is reached by antibiotic prophylaxis and washing of the surgical wound with Dekasan solution at various stages of surgical dissection.
