Abstrak. Rembesan merupakan salah satu masalah yang sering terjadi pada tanggul. Besarnya rembesan sangat dipengaruhi oleh sifat permeabilitas tanah. Permeabilitas tanah akan menurun dengan meningkatnya kadar air dalam tanah. Rembesan yang terjadi pada tanggul akan membentuk suatu pola aliran air di dalam tubuh tanggul. Rembesan air akan berjalan sejajar dengan garis muka air tanah sehingga garis rembesan juga merupakan garis aliran. Sehingga garis-garis equipotensial akan memotong garis rembesan ini sehingga jarak vertikal antara perpotongan adalah sama. Hasil yang diperoleh menunjukkan bahwa nilai debit rembesan berdasarkan rumus empiris jauh lebih kecil dibandingkan dengan metode pengukuran langsung dan program SEEP/W. Hal ini disebabkan karena pada metode empiris selain faktor permeabilitas dan dimensi tanggul, juga dipengaruhi oleh panjang zona basah. Sebaliknya, pada pengukuran secara langsung dan metode analisis dengan program SEEP/W, debit rembesan hanya dipengaruhi oleh nilai permeabilitas, tinggi muka air dan dimensi tanggul, sedangkan panjang zona basah tidak berpengaruh Analyses of Spreading Seepage Pattern on Embankment Model Abstract. Seepage are one problem that often occurs in the embankment. The magnitude of seepage is greatly influenced by the soil permeability characteristic. Soil permeability would decreased with increasing water content in the soil. Seepage that occurs in embankments would form a pattern of water flow inside the embankment. Seepage water will run parallel with the water levels line so that seepage is also a flow line. So that the equipotential lines will cut the line permeability so that the vertical distance between the intersections is the same. The results obtained indicate that the seepage discharge based on empirical formula smaller than the direct measurement method and program SEEP/W. This is due because of at the empirical method besides permeability and embankment dimension, also influenced by length of wet zone. In contrast, the direct measurement and analysis methods with the program SEEP/W, seepage discharge is only affected by the value of the permeability, water levels and embankment dimensions, while the length of wet zone does not effect.

Relevance. Alternaria dauci, Alternaria radicina and Fusarium oxysporumare wide spread and harmful fungal diseases of carrot (Daucus carota L.) in the Russian Federation and in the world. Total losses of roots from these diseases are 35-70%. Obtaining of new varieties and hybrids resistant to these pathogens is complicated by the fact of polygenic control resistance traits to fungal diseases of Alternaria and Fusarium genus. Interaction of polygenic resistance traits with environmental factors causes the soft character of changing these traits: effects of interactions between alleles and genes are changed, the dominant effect become weaker, additive effect become stronger. So, we can say about of the tolerance to complex pathogens for that case.The goal of our study is to determine the heritability of tolerance to fungal pathogens Alternaria dauci and Fusarium oxysporum by hybrids F1 of carrot.Materials and methods. Materials of studies were 7 basic lines with different types of roots; 7 prospective hybrids F1 and mycelium of Alternaria dauci and Fusarium oxysporum with spores (for inoculation). Methods of studies were: evaluation resistance of lines and hybrids F1 (seedlings, adult plants and roots) at different types of infection backgrounds; dispersion and correlation analysis. Resistance the basic lines of carrot to fungi of Alternaria and Fusarium genus was evaluated step-by-step, using several types of artificial and natural infection backhybrids F1. Tolerant samples were selected and they were used in crossings. F1 – hybrids have been obtained and they have been evaluated at artificial and natural backgrounds.Results: 1. One tolerant male form № 1268 and 6 female forms with weak sensitivity to fungi of Alternaria and Fusarium genus were selected from basic material. They were used in crossings. hybrids F1 have been obtained. 2. Analysis the heritability of carrot resistance to fungal pathogens Alternaria dauci and Fusarium oxysporum identified, that such type of resistance inherited by father’s type. 3. Using tolerant carrot line № 1268 in crossings as the male form and 6 female forms with weak sensitivity to fungal pathogens Alternaria dauci and Fusarium oxysporum increased significantly the percent of tolerant plant in 3 F1 – hybrid population under artificial infection on provocative infection background.

Black pepper is one of Indonesia's agricultural commodities, contributing foreign exchange to the country. However, the economic value of this commodity has decreased. It is influenced by the lack of diversified black pepper products, which of course, have a higher value than raw material marketing. One product diversification that can be developed is black pepper oil. In obtaining essential oils, appropriate methods and technology are needed so that the resulting product is of high quality and the process is carried out efficiently. The latest methods in extraction that are being developed are microwave and ultrasonic technology. Therefore, in this study, black pepper oil extraction was carried out using the microwave hydrodistillation method, whereas previously, ultrasonic pretreatment was given for the material. In this case, observations were made on the influence of extraction parameters. Based on the research, it was found that increasing the distiller size flask and ambient temperature could increase the percentage of essential oils yield. At the same time, the longer extraction time caused a decrease in yield. Decreasing the material particle size and increasing microwave power could cause an increase in yield up to a certain point. The best results in black pepper oil extraction were obtained under extraction conditions using a distiller size of 1000mL, extraction time of 60 minutes, at an ambient temperature of 30 oC, the particle size of 60 mesh, at a power of 450 W with a yield of 1.056%, with the characteristics of having a clear greenish colour and anRI of 1.480. These specifications comply with ISO 3061:2008 for essential oil from black pepper. Thus, these parameters can be considered in the black pepper oil extraction process to produce marketable products. As a suggestion for further research, modeling, and process scale-up can be developed.

Published: June 2023

Abstract

In order to explore the tolerance mechanism of Bidens pilosa L. to cadmium (Cd), the physiological response and Cd accumulation characteristics of plants were studied after poisoning plants with Cd. The main results were as follows: B. pilosa seedlings were not damaged after Cd poisoning. The characteristic peak intensity of leaves was higher at high Cd concentration than at medium-low Cd concentration. The intensity of characteristic peaks of stems and roots was close to or higher than that of the control group. Cd accumulation in roots was significantly lower than that in shoots after Cd treatment. Cd accumulated in leaves, but was least distributed in chloroplasts and mitochondria, and mainly in cell walls. Therefore, B. pilosa has good endurance ability against Cd-contaminated soil and has good application potential in resolving Cd-polluted soil. The Fourier transform infrared (FTIR) method is more representative than conventional methods in identifying the treatment effect of heavy metals in terrestrial plants, which provides strong evidence for the development of phytoremediation technology.
Macrophage is vital for C5b-9-induced cyst formation and enlargement in Pkd1 -/- mice

Published: June 2023

Abstract
C5b-9 complex, the final product of complement, is overproduced during cystogenesis in the kidneys of rapid-onset mice with Pkd1 gene deficiency at postnatal day (PD)10. Compared with rapid-onset polycystic kidney disease (PKD) model, cyst enlargement is much less progressive in mice when Pkd1 gene inactivation at PD30 (chronic-onset model); however, C5b-9 infusion significantly accelerated ADPKD progression in this model. These histological data provide evidence that C5b-9 triggers renal cell apoptosis in the middle stage (PD180) and promotes cell proliferation in the late stage (PD240) in PKD mice. However, in vitro C5b-9 neither stimulated renal tubular epithelial cell (RTEC) apoptosis nor promoted RTEC proliferation, indicating that the C5b-9 indirectly affects RTECs. Furthermore, our results demonstrate that the impact of C5b-9 on cyst enlargement is significantly weakened when macrophages are depleted with liposomal clodronate (LC), suggesting that macrophages play a key role in the development of ADPKD. Moreover, C5b-9 drives bone-marrow-derived macrophages (BMDMs) to highly express TNF-α in vitro, resulting in increased cell apoptosis and contributing to cystogenesis. Additionally, the macrophages underwent M1-to-M2 transition and secreted high levels of IL-10, when cocultured with RTECs. IL-10, an M2-specific cytokine marker, remarkably stimulated RTEC proliferation. After LC-induced macrophage depletion, infusion of C5b-9-activated BMDMs significantly increased cystic phenotype in mice, proving that macrophages are vital for C5b-9-induced ADPKD.

Abstract

The hilly and mountainous areas of the highlands and rift escarpments of Ethiopia are frequently affected by first time as well as reactivated landslides of different types and sizes. One of the areas affected by such hazards, a focus of this study, is the Gedo-Dilb Asphalt road and its corridor in northern Ethiopia. The objective of this research was to evaluate the characteristics and influencing factors of landslides, determine the stability conditions of critical slope sections, produce susceptibility map of the road corridor for development planning and recommend mitigation measures. The research involved: (a) detailed inventory and characterization of landslides and associated ground failures, (b) field and laboratory investigation of the engineering properties of soils and rocks, (c) slope stability analysis of selected slope sections, (d) evaluations of the various possible causative factors, defining the most influential parameters and producing landslide susceptibility map of the road corridor, and (e) recommend appropriate mitigation measures. Results of this study show that the area is affected by 103 active landslides covering an area of 8.44 km2. In steep slopes, rock-falls are common. The debris/earth slides facilitated by gully erosion have depths which range from 0.8m to 12m. Out of the a total 16Km asphalt road length, 9.5Km road section was found to be affected by various interrelated hazards including landslides, siltation of road hydraulic structures, and erosion/scouring. Based on the comprehensive field and laboratory investigations as well as slope stability analysis the causes of landslides in the study area include: (a) preconditions: lithology, slope angle, slope shape; (b) preparatory: land use/land cover, gully erosion, road excavations; and (c) triggering: rainfall. Analytical hierarchy process (AHP) approach was used to develop landslide susceptibility map and the model was validated using area under curve (AUC). The AUC value was found to be 0.82, indicating very good prediction of landslide susceptibility: 75% of the inventoried landslides fall in the high and very high susceptibility zones. This study has revealed that landslides in the area are associated with several interrelated factors which require integrated solutions including gully rehabilitation/stabilization, drainage based water management (surface and sub-surface water), and bio-engineering solutions for slope stabilization.

Abstract

Improving public restroom facilities in urban areas can contribute to ensuring the overall living standards of the urban populace. Access to improved sanitation and hygiene is also considered a fundamental human right. Therefore, the present study aims to understand public perceptions of urban public restroom use based on a case study conducted in the municipality of Kegalle township in Sri Lanka. This included a questionnaire survey (N = 115) and in-depth interviews (N = 5). The analysis indicates the urgent need for adequate, accessible, and good-quality sanitary services, particularly in densely populated urban areas of the country. More than 70% of people (from N = 115) indicate that public restrooms are not of good quality due to certain reasons such as poor maintenance and uncleanliness. Despite the insalubrity of public restrooms, many respondents have used them, indicating an urgent policy intervention in operating, and properly maintaining public restrooms in densely populated urban areas of the country. A significant number of respondents indicated that the quality of public restrooms is extremely poor (39%) or poor (31.1%). Around 86.9% of respondents are not satisfied with existing public restrooms, thus, 71.4% believe in reconstructing new public restrooms that pave the way for ensuring access, affordability, quality, and safety.

Abstract:
Calocybe indica has been considered an essential herb, exhibiting a strong antioxidant capability.
To this point, the phenolic compounds could be the primary constituent inducing such high
activity. However, the phenolic-antioxidant activity correlation still needs to be understood. This
study attempted to shed light on the direct linkage between phenolic compounds and antioxidant activity
of the Vietnam-grown Calocybe indica for the first time. It turns out that the total amount of phenolic
content is 97.67 μg/g, which is exceptionally high in the methanol extract. Gallic acid, quercetin, quercitrin,
and hesperidin account for 49.02 ± 0.18 μg/g, 15.36 ± 0.24, 18.71 ± 0.32, and 14.58 ± 0.28 μg/g of such
activity, respectively. Such antioxidants result in an extraordinary performance in DPPH and ABTS evaluations.
Indeed, the total antioxidant capacity ranges from 59.67±0.78 to 91.26±1.57 mg GA/g or from
75.25±0.32 to 88.17±0.64 μmol AS/g, corresponding to the contents of phenolics from 24.92 ±0.24 to
35.28 ± 0.33 mg GAE/g. Furthermore, flavonoid compounds have been quantified to range from
14.63 ± 0.17 to 23.88 ± 0.10 mg QUE/g. These results imply the prominence of Calocybe indica for
biomedical applications.
