On some Rings of differentiable type

Let $K$ be a field of characteristic 0 and $S=K[x_1,\ldots,x_m]/I$ be an affine domain. Consider $R=S_P$ where $P\in Spec(S)$ such that $R$ is regular. In this paper we construct a field $F$ which is contained in $R$ such that (1) The residue field of $R$ is a finite extension of $F$. (2) $D_F(R)$, the ring of $F$-linear differential operators on $R$ is left and right Noetherian with finite global dimension. (3) The Bernstein class of $D_F(R)$ is closed under localization at one element of $R$. We also prove a similar result for $R^h$, the Henselization of $R$. As an application we prove that $\frac{D_F(R)}{D_F(R)P}\cong E(\kappa(P))$ where $E(\kappa(P))$ is the injective hull of the residue field of $R$.Comment: arXiv admin note: text overlap with arXiv:1202.3597 by other author

Hybrid Separation of Circulating Tumor Cells in Zigzag and Contraction-Expansion Microfluidic Channels

Circulating tumor cells (CTCs) are cells that originate from a primary tumor cell and spread into the human body through the bloodstream. CTCs are known to be the primary indicator for early-stage cancer detection, monitoring, and treatment monitoring. Thus, the separation of CTCs is pivotal for cancer diagnosis and prognosis. CTCs can also play a vital role in revealing the mechanism of cancer metastasis. However, CTC separation from blood cells is a challenging task since the number of CTCs found in the blood is extremely low. Therefore, developing an effective, robust, and efficient CTC sorting platform is necessary to isolate CTCs with high purity and throughput. Conventional cell separation methods separate CTCs based on the size difference among the cells which makes those devices vulnerable when the size of CTCs overlap with other cells. To address this issue, we develop a hybrid method for the separation of CTCs from white blood cells (WBCs) coupling Dielectrophoresis (DEP) with inertial microfluidics. The proposed method utilizes the dielectric properties of cells in addition to the cell size. At first, a zigzag microfluidic channel is employed to separate MDA-231 CTC from WBCs which have significant size overlap with the CTCs. The proposed zigzag-shaped channel is coupled with both inertial microfluidics and DEP to isolate MDA-231 CTCs vertically from similar-sized WBCs. Interdigitated planner electrodes are attached to the bottom side of the channel and the proposed technique can achieve high throughput with a Reynolds number of 125. We have also investigated the effect of Reynolds number, voltage, and electrode configuration for enhancing separation efficiency. In the latter work, we propose a contraction-expansion channel with the combination of DEP and inertial forces to separate A549 CTCs from both similar-sized and different-sized WBCs. To get a horizontal DEP force, interdigitated electrodes are attached to the side wall of the channel. The proposed channel can separate CTCs laterally from any sized WBCs with a high separation distance. Moreover, we also analyze the effect of the number of contraction-expansion sections, voltage, and flow rate on cell migration characteristics. The proposed technique can be used for other cell beads by modifying the electric field frequency without changing the channel design

Fracture of radial neck and proximal ulna with medial displacement of the radial shaft

Introduction: Radial neck injuries are reasonably common, and when present as isolated injuries with minimal displacement or angulation, a good outcome is anticipated. Elbow injuries are common in children but radial neck fractures are relatively rare (5% to 10%) in paediatric elbow fractures. Objective: To assess the fracture of radial neck and proximal ulna with medial displacement of the radial shaft. Materials and Methods: This was a retrospective study conducted at Dept. of Ortho-Surgery, Sheikh Sayera Khatun Medical College Hospital, Gopalgonj, Bangladesh from January 2018 to December 2021. Medical records of ten patients who had displaced radial neck fractures treated at our Hospital.  Ten patients who had displaced radial neck fractures (Judet type III and type IV) treated. Patients were assessed for functional outcome by Mayo elbow performance score (MEPS), the Tibone and Stoltz functional criteria, and for complications with the average follow-up of four years (range: six months to seven years). Patients were assessed for functional outcome by Mayo elbow performance score (MEPS), the Tibone and Stoltz functional criteria, and for complications with the average follow-up. Results: The mean age of the patients was 9.12±2.2 years (range: 4 to 14 years). Eight (80%) patients were males and two (20%) patients were females. The right side was the most commonly injured side (right at 68% and left at 32%). Six (60%) cases were of Judet type III and (40%) cases were of Judet type IV. The mean fracture angulation of the series was 56.5 degrees (range 33.2 degrees to 79.2 degrees). Four patients had isolated radial neck fractures and four patients had associated proximal ulna fractures and one patient had associated posterolateral elbow dislocation. Among two patients treated with percutaneous pin leverage and intramedullary nailing by the Metaizeau technique, one patient had an excellent outcome, and the other had a good outcome. Among four cases treated with open reduction and K-wire fixation, two patients had good outcomes, one patient had a fair outcome, and one patient had a poor outcome. Conclusion: The majority of moderately to severely displaced pediatric radial neck fractures which need intervention can be managed by the closed reduction technique of Metaizeau with or without pin leverage with excellent to good functional outcomes at short-term follow-up. Some cases need open reduction which also has good to fair outcomes

Bond Strength of Fusion Bonded Epoxy-Coated Reinforcement in Concrete

Fusion-bonded epoxy-coated steel is expected to extend the service life of the reinforced concrete structure in chloride-laden environments. However, the effect of coating on the bond-strength between rebar and concrete is not well understood yet. This research, therefore, studied the effect of epoxy-coating on the bond characteristics of reinforcing bars in concrete. The bond characteristics were assessed through pullout test considering variables viz. concrete strength, embedded length and bar diameter. The load was applied to reinforcing bars embedded in concrete until bond strength between the bar and concrete exceeded. Bond strength of epoxy-coated bars was compared with that of the uncoated bars. It was found that epoxy-coating reduced the bond strength approximately 25% for Ø20mm bar and 12% for Ø16mm and Ø12mm bar. As with uncoated bar, bond strength of coated bars were also increased with concrete strength. However, the bond strength ratio between coated and uncoated bars was found almost independent of concrete strength. Based on the test results, a development length modification factor of 1.33 is proposed for Ø20mm bar and 1.15 for Ø12mm and Ø16mm bar to compensate the bond strength reduction due to the epoxy coating

Mitigating Environmental Impact Through the Use of Rice Husk Ash in Sustainable Concrete: Experimental Study, Numerical Modelling, and Optimisation

Cement production significantly contributes to CO2 emissions (8% of worldwide CO2 emissions) and global warming, accelerating climate change and increasing air pollution, which harms ecosystems and human health. To this end, this research investigates the fresh and hardened properties of sustainable concrete fabricated with three different replacement percentages (0%, 5%, and 10% by weight) of ordinary Portland cement (OPC) using rice husk ash (RHA). The hardened properties were evaluated at 14, 28, 60, 90, and 120 days of water curing. In addition, data-based models were developed, validated, and optimised, and the models were compared with experimental results and validated with the literature findings. The outcomes reveal that the slump values increased (17% higher) with the increased content of RHA, which aligns with the lower temperatures (12% lower) of freshly mixed concrete with RHA than the control mix (100% OPC). The slopes of the stress–strain profiles decreased at early ages and improved at longer curing ages (more than 28 days), especially for mixes with 5% RHA. The compressive strength decreased slightly (18% at 28 days) with increased percentages of RHA, which was minimised with increased curing ages (8% at 90 days). The data-based model accurately predicted the stress–strain profiles (coefficient of determination, R2 ≈ 0.9950–0.9993) and compressive strength at each curing age, including crack progression (i.e., highly nonlinear region) and validates its effectiveness. In contrast, the optimisation model shows excellent results, mirroring the experimental data throughout the profile. These outcomes indicate that the 10% RHA could potentially replace OPC due to its lower reduction in strength (8% at 90 days), which in turn lowers CO2 emissions and promotes sustainability

Growth performance of the marine microalgae Pavlova salina and Dunaliella tertiolecta using different commercially available fertilizers in natural seawater and inland saline ground water

Abstract Pavlova salina and Dunaliella tertiolecta were cultivated using batch culture techniques to examine their growth performance with commercial agricultural fertilizers compared to the commonly used but expensive f/2 algae culture media. P. salina demonstrated significantly higher growth rates (as measured by determination of average cell densities) when provided with f/2 media, but no growth when cultured using commercial fertilizers, namely Miracle-gro and Maxicrop. In contrast, the average cell density of D. tertiolecta was found to be significantly higher (P < 0.05) when cultured using commercial fertilizers, as opposed to f/2 media. Significant differences in lipid content were demonstrated in the Maxicrop 2.25 ml fertilizer media compared to the other treatments (P < 0.05). Finally, comparisons between natural sea water (NSW) and inland saline ground water (ISGW) have resulted in slightly higher biomass increases being observed for the NSW treatments than the ISGW treatments (P < 0.05), but also demonstrated the lucrative potential of ISGW towards aquaculture applications

ROLE OF PURUN TIKUS IN VERTICAL SUBSURFACE FLOW CONSTRUCTED WETLAND IN TREATING MANGANESE (Mn) FROM COAL MINE DRAINAGE

Constructed wetland (CW) is one of the passive methods used to process coal mine drainage. In this study, we used vertical (VF) subsurface flow (SSF) constructed wetland (CW) with purun tikus (Eleocharis dulcis). The purpose of the study was to assess the role of purun tikus in increasing the efficiency of constructed wetland to remove Mn from Coal Mine Drainage. The constructed wetland operated under batch hydraulic loading regime. The results showed that the efficiency of the VF-SSFCW System without purun tikus was 15.53% and VF-SSFCW with purun tikus 78.94%
