A Comparative Evaluation of TiO₂Suspension Coating Techniques: A Novel Technique to Achieve Optimal Thickness and Uniformity of Photocatalytic Film

International Journal of Photoenergy (2012)

Masoud Rismanchian Farideh Golbabaei Yadollah Mortazavi Gholamhossein Pourtaghi Abbas Rahimi Foroushani

The most important parameters affecting the efficiency of catalysts for the oxidation of the surrounding materials are considered to be the thickness and uniformity of the catalyst layer. The present method for the determination of thickness used in most studies is the analysis of cross-sectional pictures from SEM imaging. This method, however, has several restrictions. This study proposes a feasible and simple method for evaluating the optimal thickness and uniformity using UVA light transmitted through the samples. Three techniques for catalyst deposition have been investigated in this study using UVA light transmitted through the samples and by measuring the photocatalytic activity. These methods include lowering, dip coating, and spraying, which showed coefficients of variation for the coated catalyst weight of 28.4%, 13.6%, and 3.24%, respectively. The samples from the lowering, dip coating, and spraying techniques showed UVA transmissions of 95.02%, 68.8%, and 15.6%, respectively. The spraying technique displayed the lowest values for both. The estimated removal efficiencies (%RE/mgcm⁻²) for lowering, dip coating, and spraying were 18.42, 16.84, and 24.15, respectively. Using these analyses it was determined that the spraying technique yielded the best photocatalytic oxidation performance of the three techniques studied.

FACTORS AFFECTING ROAD TRAFFIC NOISE ANNOYANCE AMONG WHITE-COLLAR EMPLOYEES WORKING IN TEHRAN

Iranian journal of environmental health science & engineering/Iranian journal of environmental health sciences & engineering (2010)

Iraj Alimohammadi Parvin Nassiri Manoochehr Azkhosh Mostafa Hoseini

The effect of personal and attitudinal factors, noise level, hearing status and psychological traits on traffic-related noise annoyance among white-collar employees working in Tehran has been carefully analyzed. This survey has been conducted by interviewing 495 citizens working in non-manufacturing industries in Tehran, using questionnaires, Weinstein noise sensitivity scale, Beck’s depression, Buss and perry’s aggression, Zung’s anxiety, job satisfaction and Eysenc’s personality inventory. These citizens were office workers or store employees. Noise annoyance was determined both by numerical-based questionnaire criterion and by verbal index. Personal information, attitudinal factors and hearing conditions were determined using a general questionnaire. The amount of workplace noise the participants were exposed to was directly measured at their workplaces. It was revealed that among personal factors, age (p=0.030), marital status (p=0.004), residential period (p=0.001) and wealth (p=0.04) were related to noise annoyance. Attitudinal factors including sensitivity to noise (p=0.001), individual’s opinion on the need to control the noise (p=0.000) and individuals’ assessment of the amount of the workplace ambient noise (p= 0.000) were found to have relationship with noise annoyance. No meaningful relationship was seen between the equivalent noise level (p=0.879) and statistical noise level of L90 (p=0.909). The present study revealed that among all effective factors involved in noise annoyance, attitudinal factors had the most significant role in this regard.

The combined effect of industrial noise type, level and frequency characteristics on hand motor skills: A lab trial study

Work (2021)

Parvin Nassiri Mohammad Reza Monazzam Somayeh Farhang Dehghan Gholamheidar Teimori Seyed Abolfazl Zakerian

The study aimed to assess the interactive effects of industrial noise type, level and frequency characteristics on hand motor skills using the Minnesota Manual Dexterity Test and the Hand Tool Dexterity Test.A total of ten nonsmoking male volunteers with normal hearing and vision were selected for this study. The study followed a full 3×3×2 factorial design. Independent variables were noise type (steady, intermittent and fluctuating), noise level (75, 85 and 95 dBA) and frequency characteristics ("roar" <2000 Hz and "hiss" >2000 Hz).For Minnesota Manual Dexterity Test, the lowest speed is related to steady hiss noise at 75 dBA and the highest speed is related to fluctuating roar noise at 95 dBA. The speed is being significantly affected by the frequency characteristic (P = 0.041) and noise type (P = 0.025). The effect of hiss noise on speed is greater than roar noise (P = 0.038). There is a significant difference (P = 0.035) between continuous noise and fluctuating noise. For the Hand Tool Dexterity Test, the lowest speed is related to fluctuating hiss noise at 95 dBA and the highest speed is related to steady roar noise at 95 dBA. The speed is being significantly affected by the frequency characteristic (P = 0.002), noise type (P = 0.0001) and noise level (P = 0.005). The effect of hiss noise on response variable to be greater than roar noise (P = 0.008). There is a significant difference (P = 0.0001) between steady noise and the two other types of noise, and also there is a significant difference between 75 dBA and 85 dBA level (P = 0.003).The results showed that on hand motor skills, speed response was influenced by three characteristics: the type of noise, frequency characteristics and noise level. Also, the effect of the hiss noise was more than the roar noise.

Train Passengers Comfort with Regard to Whole-Body Vibration

Journal of low frequency noise, vibration and active control (2011)

Parvin Nassiri Alireza Koohpaei Hojjat Zeraati P. Jafari Shalkouhi

A case study was conducted to evaluate passengers' comfort on the Tehran-Andimeshk train in Iran. Hence, based on a=0.05, 91 passengers were selected. Whole-body vibration transmitted to the passengers was measured according to ISO 2631-1-1997. The crest factors in the the majority of wagons were below the 19 dB according to ISO 2631-1-1997 hence, the equal acceleration levels of the wagons were taken into consideration. The statistical relationships between 15 psychological and physiological disorders with age, gender, number of the trips and A eq (equivalent acceleration level) were studied based on the questionnaires. The results revealed no statistical relationships between the health symptoms and age. Conversely, there was a significant statistical relationship between fatigue and gender. Also, sleeplessness and hearing disorders bother the passengers during the trips based on statistical analysis. Moreover, there were statistical relationships between studying with headache and nausea with eating. In addition, despite all 15 symptoms bothering the passengers during the trips, there was only a significant statistical relationship between A eq (equivalent acceleration level) and anger. Hence, more factors must be taken into consideration to find the other reasons of passengers discomfort during the trips.
