  • Emission control of pollutants in waste incineration power generation process

    The waste incineration power generation is not only an effective measure to deal with the urban domestic garbage, but also can realize the supplement of the urban electric energy resources. Because of the complexity and diversification of the municipal solid waste in our country, there are different and complex chemical reactions in the waste incineration process. The reaction itself has a direct hazard to the human body and the environment, especially the highly toxic dioxins, which is a key factor to hinder the development of the waste incineration power generation technology. In order to better improve the comprehensive benefit of the waste incineration power generation, this paper briefly analyzes the emission control of the pollutants in the waste incineration power generation process, and hopes to provide theoretical help to the relevant workers.

  • A Study on Moisture Content of Bamboo Fiber Reinforced HDPE Composite at Different Temperature

    Natural fibers are becoming a competitive option as reinforcement of polymeric composite materials due to their bio-based character, good specific mechanical properties, low cost and inexhaustible supply. The aim of this study was to make the Bamboo fiber and high density polyethylene (HDPE) composite and to measure the wet loss of the composite due to removal of moisture content at 105 0C, 125 0C and 135 0C temperature. Bamboo fiber were extracted from bamboo culm and treated with 0.5 M NaOH. Bamboo fiber-reinforced HDPE composites were prepared employing melt blending technique followed by heat press molding with various weight fractions (5, 10, 30 and 40 wt. %) of the treated bamboo fiber with HDPE. A systematic investigation of the thermal behavior on the moisture content of the composites was carried out. It was observed that at 135 0C temperature more moisture removed from the composite compared to 105 0C and 125 0C temperature. It also revealed that the weight loss of the composite increased with the increase in the Bamboo fiber loading (5% to 40%).

  • Psychosis Due to Hypothyroidism: Are Antipsychotics Indicated?

    Objective: To present a case of thyroid-related psychosis and review the literature to assess evidence regarding the use of antipsychotic medications in patients who develop this condition. Data Sources: The OVID database was utilized to search for the terms “myxedema madness” and the combination of the terms “psychosis” and “thyroid.” The database was searched from 1946 until July 2018 and was limited to English language articles. Study Selection: A total of 25 articles were included in this study. These included 27 distinct case reports. Data Extraction: The abstracts of identified articles were reviewed. If an abstract was unavailable or inconclusive, the full article was reviewed. If there was no case report, or if the case was not clearly related to hypothyroidism, it was excluded. Authors assessed and identified cases included. Studies were excluded if recovery time was unreported; if cases included patients with pre-existing, chronic mental illness or intellectual disability, or if thyroid replacement medication was not initially administered. Results: Data suggested that there may be no benefit to treating thyroid-related psychosis with scheduled dosing of antipsychotics in addition to thyroid replacement. The review also suggested that male patients with thyroid-related psychosis seemed to respond more rapidly to thyroid replacement than female patients. Conclusions: Scheduled dose antipsychotic therapy was not observed to hasten recovery. Males with thyroid-related psychosis were observed to respond more quickly to thyroid replacement than females among the identified cases identified. Consideration should be given to initial trials of thyroid replacement alone in cases of thyroid-related psychosis.

  • Health Hazards with Adulterated Spices: Save the “Onion Tears”

    Spices are among the top five most commonly adulterated food types because they are expensive commodities that are processed prior to sale, used most frequently and consumed by mass population. There is a strong incentive to pollute. In Bangladesh, different types of grounded spices powders are available like onion, ginger, coriander, chilli, turmeric, cumin, etc. These powdered spices are commercially processed and packaged by some leading food industries, while some local non-branded industries also exist. Nowadays, people are busy with their carriers, the demand of branded spices powder is increasing gradually. Generally, most of the people tend to buy loose spices from the local grocery store if branded and packaged spices are not available. This increases the risk of consuming adulterated spices. Unlike this particular adulterant which is not unhealthy (but illegal), most of the adulterants are unhealthy and can cause serious and fatal damage to our system if consumed regularly. The escalating market of this product implies that in Bangladesh this tradition is increasingly attaining momentum. Spices are consumed in various forms such as whole spices, ground spices, oleoresins, extracts etc. Spices play an important role in enhancing the flavor and taste of processed foods. They are also used in medicine because of their carminative stimulating and digestive properties. Ground spices maybe adulterated with artificial colors, starch, chalk powder, etc. to increase their weight and enhance appearance. High value ground spices are frequently adulterated for economic gains. Adulteration is difficult to identify by visual and sensory inputs alone. Although there are few renowned food industries, peoples are always suspicious about these products. But there are still not enough investigations for the quality check of all these branded powdered products.

  • Foreign Body Aspiration in Adult, What Would You Expect? Case Report

    Foreign body (FB) aspiration is an uncommon but potentially life-threatening event, while the majority of accidental aspiration events occur in children, adults represent up to 25% of cases. When the diagnosis is not established immediately, retained FBs may lead to recurrent pneumonias, bronchiectasis, recurrent hemoptysis, pneumothorax, lung abscesses, pneumo-mediastinum, or other complications. Extraction of aspirated FBs should be undertaken as soon as possible to alleviate acute symptoms and prevent long term complications. FB aspiration is slightly more common in males. The vast majority of adult patients with FB aspiration have obvious risk factors for aspiration including neurological deficits with swallowing difficulties or altered mental status, neuromuscular disease, intoxication, or have an iatrogenic cause. Still, 10% of adult patients with FB aspiration have no known risk factors. Our case is 35 y old male patient who was brought to Accident and Emergency department after being found unresponsive in the street, on arrival to hospital his GCS was 9/15 with pin points pupils , spontaneous breathing and hemodynamic stable . CT brain was unremarkable Patient failed to respond to repeated doses of naloxone and his GCS dropped with episode of apnea so was intubated and mechanically ventilated. Follow up chest x-ray show opacification of the right lung, and ABG reveled hypoxia with respiratory acidosis in spite high ventilator settings, So CT chest was the best option which reveled bronchial obstruction mostly due to foreign body. Urgent bronchoscopy was done and unexpectedly obstruction was due to chewing gum pieces, aspiration of four large pieces of chewing gum, following that patient remained in the ICU for 2 days where chest x-ray show significant improvement and he was weaned and extubated successfully.

  • Heavy Metals in Soil and Vegetables Irrigated with Ex- Tin Mining Ponds Water in Barkin – Ladi Local Government Area Plateau State, Nigeria

    Tin mining pond water irrigated fields can cause potential contamination with heavy metals to soil and vegetables, thus pose a threat to human beings. The current study was designed to investigate the contamination of the soil with toxic heavy metals and their accumulation in edible vegetable crops. The heavy metals Pb, Cu, Cd, Zn, Cr, Fe, Mn and As were analyzed for their bioaccumulation factors to provide baseline data regarding environmental safety and the suitability of tin mining pond water for irrigation in the future. The contamination factor (CF) of these metals in the soil were calculated and indicated levels of metal contamination in the order of Cd > Zn > Pb > Cr > Cu > As ˃ Fe ˃ Mn. The concentrations of Pb, Cd, Cr, As, and Mn in the edible vegetables were above the safe limit prescribe by FAO/WHO, 2007 and EU, 2002 in all studied vegetables. The results indicated a potential pathway of human exposure to slow poisoning by heavy metals due to the utilization of vegetables grown on heavy metal contaminated soil that was irrigated with tin mining pond water sources. Amongst the studied vegetables, cabbage was safe from other metal except for As and Cr that were observed to exceeds tolerable limit. The irrigation source was identified as the source of the soil pollution in this study. Thus, the consumption of these vegetables might poses substantial health risk to consumers for this reason we therefore, emphasizes the need for proper remediation of the wastewater to reduce the health risk and the extent of heavy metals contamination.

  • Finding Waldo: Two Routes for Processing Visual Search in Complex Scenic Images

    This paper reviews the cognitive mechanisms underlying visual search in complex visual images. Visual search is a type of task that we are constantly engaged in our everyday lives. Here, the current paper introduces the current literature that suggests that there are two different processing routes that support visual search in human observers: Bottom-up and Top-down processing. Bottom-up processing allows the visual system to process the sensory information from the visual image as it is, whereas top-down processing guides the visual system to efficiently allocate attention to a part of the image to facilitate the search process. The two processing routes via bottom-up and top-down processing work in concert during complex visual search, guiding our search behavior to be more efficient and adaptive. In closing remark, this review also briefly discusses how the current knowledge about the roles of bottom-up and top-down processing in visual search can contribute to development of computer vision and artificial intelligent.

  • Removal of natural organic matter from water using chemically activated coffee husk

    The presence of natural organic matter (NOM) in source water has posed many challenges for conventional water treatment facilities. Small organic acids, such as humic acid, present in NOM, have a high potential to influence the performance of water treatment processes. Uncontrolled application of agricultural chemicals leads to the simultaneous presence of toxic substances. In this work, batch adsorption experiments were conducted to examine the biosorption of HA onto chemically activated coffee husk. The biosorption process was studied as a function of operating conditions, such as contact time, pH of the solution, HA concentration, adsorbent dose and agitation speed parameters. Experimental results showed that the adsorption has an equilibrium time of 60 min with a maximum adsorption of 93.7%. The optimum pH for maximum HA adsorption was found to be 5.5, with a maximum adsorption of 94.3%. . As the dose of adsorbent increased from 1 to 25 g/L, the concentration of HA was observed to reduce from 10 to 1.67 mg/L which is below the WHO (World Health Organization) guideline value of 2 mg/L. The amount of HA adsorbed increased with increasing the initial adsorbent concentration from 0.5 to 20 mg/L. The adsorption kinetics well fitted the pseudo-second order model with the correlation coefficient R2 = 0.997 and Ks = 0.078. The experimental sorption equilibrium can be represented by the Langmuir isotherm (R2 = 0.998, SSE = 0.006). An average desorption capacity of 87.3% was observed. The study shows that chemically activated coffee husk can be a potential candidate to be used as a biosorbent in the removal of NOM from aqueous solutions.
