Potato (Solanum tuberosum) crops have experienced a 22% reduction due to attacks from microbial pathogens and pests. Dry rot disease occurred from risks in El-Minya governorate, Egypt, where potato is the major cultivated crop. Potato cultivar ‘Cara’ samples were collected from the markets of six regions in El-Minya for isolation. They were also tested for the application of biosynthesized zinc oxide nanoparticles (ZnONPs) for disease management. The ability of Exserohilum rostratum to synthesize ZnONPs was documented via UV-visible, X-ray diffraction, Fourier transform infrared spectrum, and transmission and scanning electron microscopy. Spherical shape and crystallite small size (51.0 ± 3.0 nm) were attributed to the created ZnONPs. The ZnONPs were applied in the bio-control of the causative agent (Fusarium nygamai) of dry rot disease and large economic loss of potato cv. ‘Cara’ productivity. The mycosynthesized ZnONPs by E. rostratum at 100 μg/ mL (3 mM) showed antifungal activity against F. nygamai with higher reducing value of mycelium growth diameter 2.0 ± 0.14 cm compared to Revanol 50%, traditional product with a diameter of 3.85 ± 0.10 cm. Overall, ZnONPs are an excellent agent that can be applied to repress the most common fungal disease of potato.

The use of lignocellulosic residues as feedstocks for biofuels production represents an economic and ecofriendly option, since they are generated as byproducts or wastes from different industrial areas. Nevertheless, a pretreatment method aimed at eliminating the lignin content of these residues must be performed. This is required in order to increase cellulose bioavailability, which favors the production of reducing sugars through microbial or enzymatic attack. Some performed pretreatments can be classified as physical, chemical, and physicochemical methods. Although such methods are the most used pretreatments, they are expensive and generate or make use of harmful compounds. Biological methods, by the action of microorganisms or their enzymes for lignin content reduction, may be regarded as an alternative, being cheaper and more friendly to the environment than the aforementioned methods. However, until now, biological pretreatments have not shown the same yield as the previously mentioned methods in both sugar recovery and biofuel production. In that sense, the aim of this work is to review the efficiency of these methods, with the goal of clarifying their advantages and disadvantages for improvement of biofuel production.

The acoustic emission analysis method was used to determine the activity of very young Hylotrupes bajulus larvae in their long-term development. In the laboratory conditions the simulated scenario of a fresh, intense infestation inside the construction wood was evaluated. The sounds generated by the insects during their feeding on the wooden samples were processed by the measurement system, which was able to detect and count the larva-originated sound pulses and calculate related energy. So far, no one has examined possibilities of detecting infant larvae of Hylotrupes bajulus L. This work is a continuation of research on the influence of the insect mass on its AE-based detection. The experiments performed with multiple wood samples analyzed through the period of one year have shown dependency between the mass of the larva and the intensity of the sound generated by them. The moment of the earliest possible detection of infestation in the wooden structure was evaluated. In the appropriate conditions (large number of young larvae inside the wood and optimal temperature) the insects reach the mass of tens of mg, which makes them detectable using the AE method.

This work was conducted using the Picoscope signal extraction procedure, which revealed significant insights regarding the belian wood and its application in Gendang Melayu Sarawak (GMS) production. The amplitude of belian wood GMS signal remains constant, allowing it to sustain its timbre for a longer duration compared to durian wood GMS using the same procedure. Considering that the dimensions of the big belian (BB) and big durian (BD) GMS are almost the same, both GMS yield almost the same note, i.e. G1# (51.9 Hz). Considering that the dimensions of both the small belian (SB) and small durian (SD) GMS are almost the same, both GMS yield almost similar note, i.e. F3 (174 Hz) and E3 (164 Hz). Although both BB and BD showed consistent harmonics, BD only displays 2 harmonics. The SB and SD both display consistent harmonics. Both BB and BD showed pleasing tonal qualities. These occurred due to the closeness of the principal overtones to the consonant interval.

Children’s study tables are an integral part of a child’s learning life. Consumers are often attracted to their styling when deciding on the use and purchase of a children’s study desk. This study focused on consumption preference for the styling of children’s study desks and delved into the factors that influence these preferences. An important aspect of this research is to understand how different shapes of children’s desks influence consumer preferences through morphological analysis. The study breaks down these desks into six different parts based on morphological analysis: backplane, bookshelves, desktop, cabinet, drawer, and table legs. Through a hierarchical analysis (AHP) and pairwise comparisons, the study created a hierarchy of preferred morphological elements. The hierarchy ranked the importance of each element in influencing consumption preference, revealing the order of preference from backsplash to table legs. In addition, by integrating personal interviews and employing Qualitative Comparative Analysis (QCA), this study provides insights into the most preferred components – backplane and bookshelves. This integrated approach revealed a preference for desks with curved backsplashes and multi-tiered functional shelves, which was ultimately validated by successfully combining weighted rankings of specific component styles.

Biochar (BC) was used in Trichoderma sp. culture to produce high-activity cellulase on a laboratory scale. The biochar was added into the flask before being applied to the fermenter to identify the enhancement effect and to determine the best amount of addition and the most suitable incubation period. Cellulase production was performed with a working volume of 4 L, and enzymatic hydrolysis was conducted to evaluate the saccharification ability of the enzyme. During incubation, the activities of three enzymes (Endoglucanase (EG), β-glucosidase (BGL), and cellobiohydrolase (CBH)) were measured for three days, and the cellulase activity was determined using a filter paper unit (FPU). In flask scale, EG, BGL, and CBH activities were increased by 1.4, 2.1, and 1.8 folds, respectively, and the incubation period was shortened by adding BC. In the fermenter scale, EG, BGL, and CBH activities were noticeably enhanced by 12.1, 5.8, and 7.2 folds, respectively, and FPU was 42.1 (9.8 folds). Additionally, the conversion rates of cellulose and steam exploded softwood and hardwood were 109.4%, 75.4%, and 87.3%, which were similar to a commercial enzyme (Cellic CTecⅡ). This study demonstrated that biochar could be used to produce high-activity cellulase in a shorter period and suggests a novel method for effective cellulase production.

This study demonstrated that biochar could be used to produce high-activity cellulase in a shorter period and suggests a novel method for effective cellulase production.","PeriodicalId":503414,"journal":{"name":"BioResources","volume":"28 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139863817","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Children’s study tables are an integral part of a child’s learning life. Consumers are often attracted to their styling when deciding on the use and purchase of a children’s study desk. This study focused on consumption preference for the styling of children’s study desks and delved into the factors that influence these preferences. An important aspect of this research is to understand how different shapes of children’s desks influence consumer preferences through morphological analysis. The study breaks down these desks into six different parts based on morphological analysis: backplane, bookshelves, desktop, cabinet, drawer, and table legs. Through a hierarchical analysis (AHP) and pairwise comparisons, the study created a hierarchy of preferred morphological elements. The hierarchy ranked the importance of each element in influencing consumption preference, revealing the order of preference from backsplash to table legs. In addition, by integrating personal interviews and employing Qualitative Comparative Analysis (QCA), this study provides insights into the most preferred components – backplane and bookshelves. This integrated approach revealed a preference for desks with curved backsplashes and multi-tiered functional shelves, which was ultimately validated by successfully combining weighted rankings of specific component styles.
