Published: January 2024

Concrete is the most dynamic engineering material in construction due to its durability and strength properties, which have been used in almost all types of physical infrastructure construction. Crushed stone dust is a supplementary material that can be utilized to produce sustainable concrete. The concept of replacing natural fine aggregate in concrete production with stone dust (SD) could enhance the consumption of stone dust produced during aggregate production as well as reduce the requirement for landfill area for stone dust management. The study aims to compare the compressive strength of nominal mixed M20 and M25-grade concrete by replacing fine aggregates with stone dust. The results reveal that compressive strength increases with an increase in stone dust, but the rise in SD percentages beyond a certain level has a negative impact on the strength of concrete. However, fresh density has a similar trend of compressive strength, and the workability of concrete shows a declining trend with a rise in SD levels. From the results of the experimental investigations conducted, it is concluded that the SD can be used as a replacement for fine aggregate. It is found that 40% replacement of fine aggregate by SD gives a maximum compressive strength than normal M20 and M25 grade concrete, which starts decreasing beyond 40% replacement. The compressive strength of the concrete has been quantified by replacing sand with varying percentages of stone dust and found that it does not satisfy the specification except for 40% replacement for M20 grade concrete, though it can be used for low and medium strength concrete production. The cost savings for M20 and M25-grade concrete at 40% sand replacement are 8.23% and 7.62%, respectively.

Аналітично доведено, що у відомих двигунах максимальний ступінь стиску на малих навантаженнях не перевищує 12...14 через зниження ефективного ККД внаслідок значних втрат на тертя. Це обмежує можливість подальшого підвищення паливної економічності за рахунок збільшення ступеня стиску понад 14. Зазначено, що одним із можливих конструктивних варіантів двигуна, що забезпечує реалізацію змінного ступеня стиску понад 14, є безшатунний ДВЗ, в якому замість звичайного кривошипно-шатунного механізму застосовується кривошипно-кулісний механізм. Відмінною рисою двигуна із кривошипно-кулісним механізмом є низькі втрати на тертя у всьому діапазоні навантажень і частоти обертання, повна динамічна врівноваженість і рівномірність ходу, а також компактність і мала питома маса. Ці переваги пов'язані з тим, що в безшатунному двигуні поршні роблять строго прямолінійний рух, у зв'язку з чим бічні навантаження на них відсутні.
Виконано розрахунково-теоретичні дослідження безшатунного ДВЗ з кривошипно-кулісним механізмом, які дозволяють припустити про доцільність використання в такому двигуні змінного ступеня стиску.
Розроблена методика розрахунку механізму зміни ступеня стиску (МЗСС), що враховує взаємозв'язок параметрів механізму й робочого циклу двигуна.
Отримано, що на базі безшатунного двигуна з кривошипно-кулісним механізмом можливе створення двигуна з ε = var з достатньою швидкодією МЗСС для запобігання детонації.
Встановлено, що зменшення частоти обертання колінчастого вала суттєво підвищує швидкодію механізму, а середнє значення швидкості зміни ступеня стиску становить від 0,29 до 0,5 цикл-1 на режимі максимального крутного моменту і може підвищуватися до 7 разів по зовнішній швидкісній характеристиці двигуна.

Soil solarization as a non-chemical weed control method in tree nursery production systems of the Pacific Northwest, USA
Authors: Wada Nami , Berry Pete A. , Hill Brian , Mallory-Smith Carol , Parke Jennifer L. 
Published: January 2024

IntroductionHerbicide application in tree nurseries is limited because of the potential for chemical injury to the large diversity of trees species grown, the lack of registered products, and increasing restrictions on herbicide use, necessitating the costly practice of hand weeding. Soil solarization can reduce the weed seedbank by trapping solar energy under clear plastic film, resulting in high soil temperatures lethal to imbibed weed seeds and seedlings. The objective of this study was to determine if soil solarization would be an effective weed management strategy in Pacific Northwest, USA, tree production systems.MethodsField studies were conducted at three commercial tree nurseries in Oregon and Washington over two years to test soil solarization in reducing the naturally occurring weed seedbank and the time required to hand weed fields. Further field and laboratory tests were conducted with five weed species: Poa annua, Polygonum pensylvanicum, Amaranthus retroflexus, Portulaca oleracea, and Cyperus esculentus. Weed seeds and tubers were buried in packets at 5 and 10 cm to determine their viability after 6 weeks of solarization. A laboratory study was conducted with all but C. esculentus to quantify the exposure time at 45, 50, and 55°C required for 90% death (T90).ResultsSoil solarization was particularly effective in reducing the emergence of naturally occurring weeds in the fall and winter, when weed emergence was reduced by 94-96%. Emergence was reduced 67-81% during the subsequent spring and early summer. Nine to ten months after solarization, solarized areas had a 52 – 69% reduction in hand weeding time compared to non-solarized areas. In field trials with buried seed and tuber packets, mortality differed by location and depth, with P. annua and P. pensylvanicum having the greatest percent seed mortality followed by A. retroflexus and variable results for P. oleracea and C. esculentus. In lab studies, seed mortality differed depending on species and temperature; however, at 55°C, there was a relatively rapid drop in seed viability for all species, and T90 values ranged from 1.2 to 41 h whereas at 45°C the range was 47 to &gt; 3000 h. Similar to the field studies, P. annua and P. pensylvancium were more sensitive to heat, followed by A. retroflexus and P. oleracea.ConclusionSoil solarization can be an effective weed management tool in reducing the weed seedbank in Pacific Northwest tree nurseries and other fall-sown crops but may not work for certain, thermotolerant weed species such as C. esculentus.

Published: January 2024

Background: Among a variety of biomaterials supporting cell growth for therapeutic applications, poly (l-lactide-co-ε-caprolactone) (PLCL) has been considered as one of the most attractive scaffolds for tissue engineering owing to its superior mechanical strength, biocompatibility, and processibility. Although extensive studies have been conducted on the relationship between the microstructure of polymeric materials and their mechanical properties, the use of the fine-tuned morphology and mechanical strength of PLCL membranes in stem cell differentiation has not yet been studied.Methods: PLCL membranes were crystallized in a combination of diverse solvent–nonsolvent mixtures, including methanol (MeOH), isopropanol (IPA), chloroform (CF), and distilled water (DW), with different solvent polarities. A PLCL membrane with high mechanical strength induced by limited pore formation was placed in a custom bioreactor mimicking the reproducible physiological microenvironment of the vascular system to promote the differentiation of mesenchymal stem cells (MSCs) into smooth muscle cells (SMCs).Results: We developed a simple, cost-effective method for fabricating porosity-controlled PLCL membranes based on the crystallization of copolymer chains in a combination of solvents and non-solvents. We confirmed that an increase in the ratio of the non-solvent increased the chain aggregation of PLCL by slow evaporation, leading to improved mechanical properties of the PLCL membrane. Furthermore, we demonstrated that the cyclic stretching of PLCL membranes induced MSC differentiation into SMCs within 10 days of culture.Conclusion: The combination of solvent and non-solvent casting for PLCL solidification can be used to fabricate mechanically durable polymer membranes for use as mechanosensitive scaffolds for stem cell differentiation.
