Fresh Tomato

A study was conducted to assess the performance of evaporative coolers for the storage of fruits and vegetables. Two evaporative coolers [Aluminum-cladded burnt-clay-brick evaporative cooler (ABBEC) and non-cladded burnt-clay-brick evaporative cooler (NBBEC)] for the storage of fruits and vegetables were designed, constructed and tested. The evaporative coolers comprised of double burnt-brick walls (1.29×2.55×2.56 m) external and (1.13×1.27×2.08 m) internal, (L×W×H). The physicochemical, microbiological and sensory attributes of fresh tomatoes stored in the coolers and at ambient were evaluated. Metabolic rates of tomatoes were highest at ambient storage followed by NBBEC with the least value in ABBEC. Beta carotene, ascorbic acid and acidity decreased while total soluble solids, pH and microbial loads increased during storage of tomatoes. Fresh tomatoes stored in ABBEC exhibited lower biochemical and physiological reaction rates hence tissue breakdown, colour changes, pH and titratable acidity were lower in ABBEC than NBBEC and ambient. ABBEC storage further improved the microbial quality and shelf life of fresh tomatoes. The aluminum cladded evaporative cooler was the best storage facility for stop gap extension of shelf life of tomatoes.

Good Agreement

This work performs experimental investigations on concrete made with difference replacement percentage of first-class burnt clay brick aggregate (0, 10, 20, 30, 40, 50, 60, 80, and 100%) by steel slag (SS) aggregate. The aim is to evaluate the mechanical properties as well as durability performances, additionally, water absorption porosity test is performed to investigate the influence of steel slag aggregate on the durability of tested concrete. The experimental results have shown that the compressive strength was improved significantly due to the replacement of brick aggregate by steel slag aggregate. The crushing strength of concrete made with 100% steel slag aggregate has gained up to 70% more than the control concrete (100% brick aggregate). However, the porosity of concrete was reduced with the adding percentage of brick aggregate by steel slag aggregate which is consistent with the compressive strength results. Further, a quite good agreement between compressive strength and porosity was observed as well.

Vibrational Characterization

The present paper shows the vibrational characterization tests of a clay brick heritage construction from XIX century, the Nossa Senhora das Dores Church, placed in Sobral, Brazil. In this study the calibration of the 3D finite element numerical model of the church was performed through ambient vibrational testing using the first three natural frequencies identified. The obtained results, namely the natural frequencies identified, and the calibrated model intends to give a contribute for understanding of the structural behavior of the Brazilian heritage constructions, and introduces relevant information for be used for safety assessment of the church along the time.

Five greenhouses with different typical wall configurations were studied, including the hollow brick wall (HB), clay brick wall composed of mural column (MCCB), wall composed of fly ash air block brick (FAABB), clay brick wall composed of plum small hole column (PSHCCB), common clay brick wall with Styrofoam wall outside (SCB) to find out the effects of the north walls on the greenhouse microclimate. The interior temperature and RH environment, as well as the heating rate, cooling rate and the correlation with the outside temperature, were tested and compared, finding that the greenhouse with FAABB exhibits the optimal temperature and RH environment, and also the highest thermal stability. The findings may provide references for greenhouse construction and insulation measures.

Evaporative Cooler

A study was conducted to assess the performance of evaporative coolers for the storage of fruits and vegetables. The evaporative coolers used for this study consist of double-walled rectangular brick construction (1.29 × 2.55 × 2.56) m external and (1.13 × 1.27 × 2.08) m, internal, (length × width × height) with the inter-space filled with river bed sand saturated with water. In this study, ambient storage temperature ranged from 26.6 to 28.7oC with relative humidity which ranged from 64.7 to 85.2 percent. However, NBBEC storage recorded lower temperature within the range of 24.3 to 25.3oC and relative humidity which ranged from 88.8 to 91.2 percent while ABBEC storage recorded the least temperature which ranged from 23.0 to 24.1oC with highest relative humidity which ranged from 91.4 to 92.8 percent. The papaya fruits stored in the coolers and in ambient were evaluated for weight loss, total soluble solids, pH, total titratable acidity, ascorbic acid, beta carotene content and microbial load. TTA, ascorbic acid, beta carotene decreased; while pH and TSS increased with storage period. In ambient storage, fresh papaya fruits stored in evaporative coolers have lower microbial load compared to ambient storage with aluminum cladding of the cooler (ABBEC) further improving microbial quality and shelf life. The pawpaw fruits stored in the aluminum cladded burnt-clay-brick evaporative cooler (ABBEC) remained fresh and firm for ten days compared to three days in non-cladded burnt-clay-brick evaporative cooler (NBBEC) and four days in ambient storage.
