UD Fafa Mutiara is a business entity that produces petis as its main product. Products that are considered defective or cannot be repaired and recycled again, will be detrimental to business actors. It is estimated that in each product there are an average of 70 plastic products that are damaged, defective, or even fail, out of 5,000 plastics every month. In a day, Mrs. Ulfa can produce around 175 plastic cases which must be marketed the next day. The purpose of this research is to find out strategies that can improve the quality of UD Fafa Mutiara's petis. One way to find several problems in failure during the petition manufacturing process is known as the Failure Mode and Effect Analysis method, which is abbreviated as FMEA. This method is used to identify potential failures that may occur in the design, production process, or production results. AHP (Analytical Hierarchy Process) has a meaning as a functional hierarchy with the main input being human presumption, which has many advantages in explaining the decision-making process. The research results obtained were that the highest level of risk in the paste production process was when washing raw materials using dirty water with an RPN value of 448. The strategy of using AHP resulted in suggestions for improvements with the highest value, namely checking water with a value of 0.366. So the recommendation that can be given to UD Fafa Mutiara is to maintain the quality of the water used for washing raw materials.
Highlight :

Identification of potential failures: FMEA method helps identify possible failures in design and production processes.
Decision-making process: AHP involves human input to explain decision-making processes effectively.
Risk mitigation strategy: Maintaining water quality during raw material washing is crucial for improving product quality.

Published: March 2024

Abstract
The 2.45–2.20 Ga period during the early Paleoproterozoic era is considered to have witnessed a global “Tectono-Magmatic Lull (TML)” and thus marks a relatively quiescent period. Our study unveils a 2.45–2.20 Ga magmatic suite from the Xiong’ershan area in the southern North China Craton, offering some key constraints on localized active tectonics during the TML. Zircon U-Pb dating shows Paleoproterozoic ages for the meta-basalt (2.31, 2.28 Ga), Na-rich meta-andesite (~2.33 Ga), tonalite-trondhjemite-granodiorite (TTG) gneisses (2.36, 2.30 Ga), K-rich granodiorite (~2.29 Ga), and monzogranite (2.33, 2.27 Ga). The meta-basalts geochemically and petrographically belong to calc-alkaline basalts and show distinctive Nb, Ta, and Ti contents and primitive mantle normalized patterns from different places in the Xiong’ershan area. Combined with their enriched εHf(t) values, the magmas were derived from subduction-related enriched mantle sources within a convergent plate boundary. The meta-andesites display high MgO content (average 4.5 wt%) and Mg# (44–57), strongly fractionated rare-earth pattern, calc-alkaline affinity, and negative Nb, Ta, and Ti anomalies. The TTG gneisses are of high SiO2 type (&gt;62 wt%), high (La/Yb)N (17.5, 39.2), and Sr/Y (50.2, 104.3) and mostly display positive Eu anomalies and high-pressure type. Zircons from these rocks show a relatively narrow range of δ18O isotope values (5.35‰, 6.79‰) with εHf(t) isotope characteristics (−9.3, −3.3), suggesting derivation from partial melting of a thickened mafic lower crust. The youngest K-rich granodiorite and monzogranite show high K2O/Na2O ratios (0.65, 2.45). Variable molar ratio Al2O3/(CaO+Na2O+K2O) (A/CNK) and low zircon εHf(t) values suggest that the K-rich granitoids formed from the partial melting of different levels of crust. The presence of meta-basalt to andesite assemblages and diverse intermediate to felsic magmatic rocks implies magmatic activity within a convergent plate boundary tectonic environment with potential influence from plume-triggered extensional processes, supported by evidence of slab rollback and upwelling of mantle material.

Abstract
The biological barriers present in the intestine thwart the absorption of orally delivered biologics, which, if overcome, would reduce the injection burdens for millions of patients. Here, we present a straightforward yet effective oral biologic formulation, which utilizes in-situ growing poly(disulfide)s as the sole excipient to circumvent all intestinal barriers in a noninvasive way. We find that, through dynamic covalent disulfide exchange initiated by the thiols in mucins, epithelial membranes, and hepatic sinusoids, digestion-resistant complex coacervates formed from insulin (as a model drug) and guanidinium-containing poly(disulfide)s readily traverse the mucus and epithelial layers without remodeling the barriers’ integrity, and then undergo dissociation to release insulin in the liver. Oral gavage of the complex coacervates with enteric capsules into diabetic mice and swine models elicited a-few-hour longer hypoglycemic effect than subcutaneously injected insulin, attaining relative bioavailabilities over 20%. 14-day dosing experiments demonstrated the postprandial and daily glycemic control capacity and the biosafety of this oral insulin. The generality of this formulation scheme was further validated with human serum albumin and salmon calcitonin.

Abstract
In correlated quantum materials, the intertwinement of multiple orders leads to rich exotic quantum states of matter and emergent phenomena. Recently, the discovery of superconductivity and charge density waves (CDWs) with multiple symmetry breakings in kagome superconductors AV3Sb5 (A = K, Rb, Cs) offers a new territory to study intertwined orders. Elastoresistance, which detects the electric resistance in response to an applied strain, offers a unique method to investigate the evolution of intertwined orders in AV3Sb5. Here, we perform a systematic measurement of elastoresistance in two hole-doped CsV3Sb5 series: CsV3Sb5-ySny (y = 0.04 and 0.06) and CsV3-xTixSb5 (x = 0.03, 0.05 and 0.09). Below the CDW transition temperature (TCDW), the elastoresistance coefficient in all samples undergoes a jump-like transition at TCDW and then another kink-like transition at a lower temperature (T*). Based on a Ginzburg-Landau analysis of CDW order, the jump-like transition at TCDW is well explained by a triple-Q CDW driven by lattice instability, while the kink-like transition around T* is ascribed to an interaction-driven quantum melting of triple-Q CDW, which leads to a nematic CDW state at low temperatures. Interestingly, the T* in all samples follows a perfect anti-correlation with the superconducting transition temperature (Tc), indicating an intertwinement of superconductivity and nematic CDW. Strikingly, the elastoresistance coefficient of Sn-doped samples exhibits a distinct temperature dependence from that of pristine and Ti-doped samples above TCDW, which is ascribed to a charge stripe instability enhanced by Sn doping. Our present findings provide a new perspective to understand the intertwined orders in kagome superconductors AV3Sb5.

Published: March 2024

Abstract

Purpose
To evaluate the accuracy of the Local-Regional 2-week wait (2WW) referral pathway for peri-ocular cancers.
Methods
Clinicodemographic and pathological data available on our electronic health records were extracted for patients referred to specialist periocular oncology service under the suspected eyelid cancer pathway between July 2019 and May 2022. Descriptive statistics were computed along with the chi-square exact test to determine the statistical significance between the referrals and referrals that were rejected/downgraded on the biopsy and biopsy-proven cancer diagnosis rates.
Results
199 referrals were included for analysis. 145 of these were from accepted 2WW pathway referrals. Most were referred using the regional suspected ocular tumour form through their general practitioner, 113/145 (78%). The average time to be first seen at our service from the initial referral was 11 days (± 5). 81 out of 145 patients (56%) underwent biopsies with a cancer diagnosis yield of 14/81 cases (17%). The most common cancer diagnosis was basal cell carcinoma representing 12/81 (15%) of all biopsy-proven diagnoses.
Conclusion
We found the overuse of urgent suspected periocular cancer referral care pathway attributable to incomplete referral information. We recommend the development of a peri-ocular cancer-specific referral form to reduce the burden on services, focusing care to patients who require urgent referrals. More education is required for referring clinicians to ensure they are aware of benign peri-ocular conditions and prevent undue stress to patients. The generalisation of these findings outside the UK population requires corroboration internationally.
Optimal seasonal schedule for the production of isoprene, a highly volatile biogenic VOC
Authors: Iwasa Yoh , Hayashi Rena , Satake Akiko 
Published: March 2024

Abstract
The leaves of many trees emit volatile organic compounds (abbreviated as BVOCs), which protect them from various damages, such as herbivory, pathogens, and heat stress. For example, isoprene is highly volatile and is known to enhance the resistance to heat stress. In this study, we analyze the optimal seasonal schedule for producing isoprene in leaves to mitigate damage. We assume that photosynthetic rate, heat stress, and the stress-suppressing effect of isoprene may vary throughout the season. We seek the seasonal schedule of isoprene production that maximizes the total net photosynthesis using Pontryagin's maximum principle. The isoprene production rate is determined by the changing balance between the cost and benefit of enhanced leaf protection over time. If heat stress peaks in midsummer, isoprene production can reach its highest levels during the summer. However, if a large portion of leaves is lost due to heat stress in a short period, the optimal schedule involves peaking isoprene production after the peak of heat stress. Both high photosynthetic rate and high isoprene volatility in midsummer make the peak of isoprene production in spring. These results can be clearly understood by distinguishing immediate impacts and the impacts of future expectations. (195 words)

Published: March 2024

Abstract

Ghaf, a resilient tree in arid environments, plays a pivotal role in ecological restoration, desertification mitigation, and cultural heritage preservation. However, the seeds' inherent challenges, notably their hard outer coating restricting germination, emphasize the pressing need for innovative strategies. This work aimed to investigate the optimization of Ghaf seed germination process through seed priming with ZnO nanoparticles treatment (duration (t), concentration (c), temperature (T) and agitation (a), employing the Taguchi method for efficient experimental design. Notably, it revealed that concentration is a pivotal influencer in the optimization of Ghaf seed. The results showed that the concentration of ZnO nanoparticles has no linear relation with any other parameters. To verify the outcomes, validation tests were performed utilizing the predicted optimal parameters. The observed low error ratio, falling within the range of 1–6%, confirmed the success of the Taguchi methodology in identifying optimal levels of the factors chosen. Significantly, ZnO-primed seeds showcased a remarkable enhancement in Ghaf seed germination, increasing from 15–88%. This study introduces a novel approach utilizing ZnO nanoparticle treatment optimized through the Taguchi method, significantly enhancing seed germination rates of Ghaf seeds and offering a promising avenue for sustainable agricultural practices in arid environments.

Abstract
Background
Hepatocellular carcinoma with spontaneous rupture (rHCC) is managed through conservative treatment, emergency resection, and trans-arterial embolisation. However, peritoneal implantation metastasis (PIM) remains highly likely owing to intraperitoneal free cancer cell dispersion within the abdominal cavity before achieving haemostasis. Although resection combined with hyperthermic intra-peritoneal chemotherapy (R-HIPEC) is used in cancer treatment, its effectiveness in preventing PIM of rHCC remains uncertain. This study aimed to evaluate the effectiveness of R-HIPEC in reducing peritoneal implantation metastasis of rHCC.
Methods
Data from 83 rHCC patients treated at Zhujiang Hospital of Southern Medical University between February 2013 and July 2023 were retrospectively analysed. Patients were categorised into interventional, resection, and R-HIPEC groups. PIM rates, time to recurrence-free survival (RFS), survival time, and other risk factors were analysed using the logistic or Cox regression model. Variables with P < 0.1 in the univariate analysis were included in the multivariate analysis.
Results
The resection and intervention groups showed no significant differences in PIM (64.5% vs 61.9%, P = 0.848), RFS (3.7 vs 4.3 months, P = 0.852), and overall survival (OS) (20.5 vs 6.9 months, P= 0.054). The R-HIPEC group exhibited lower PIM rates (23.1% vs 63.5%, P= 0.009) and longer OS (P = 0.045) than the non-HIPEC group, and the median OS was not reached in the R-HIPEC group. The R-HIPEC group had superior RFS (5.8 vs 3.6 months, P = 0.084) than the non-HIPEC group; however, the difference was not statistically significant. Multivariate analysis revealed that R-HIPEC was associated with lower PIM (odds ratio: 0.235, 95% confidence interval 0.056–0.981, P = 0.047).
Conclusions
R-HIPEC significantly reduced the occurrence of PIM, extended the RFS and OS in rHCC patients, and enhanced the overall prognosis.

Published: March 2024

Abstract
The current study reports new sulfonamide-triazole-glycoside hybrids' design, synthesis, and anticancer activity. The target glycosides' cytotoxic activity was studied with a panel of human cancer cell lines. Azido sulfonamide compound 4 exhibited moderate activity against A-549 and HCT-116 and excellent potency against HepG-2 and MCF-7. Replacement of the azido group with 1,2,3-triazole- glycoside hybrids in 6-13 afforded variable activities against tested cell lines ranging from weak to excellent ones in acetylated glycosides 6-9. On the other hand, hydroxylated glycosides 10-13, revealed weak cytotoxicity except N-cyclohexylbenzene derivatives 11, 13 expressing promising activity against HepG-2.
In addition, the hydroxylated glycoside 13 gave moderate activity against MCF-7. To detect the probable action mechanism, the inhibitory activity of the promising sulfonamide-triazole-glycoside hybrids was studied against VEGFR-2, carbonic anhydrase isoforms hCA IX and hCA XII. Moreover, the docking evaluation was simulated to supply better rationalization and gain insight into the binding affinity between their targeted enzymes and the promising derivatives and used for further modification in the anticancer field.

Authors: Shopa Mykola , Ftomyn Nazar , Shopa Yaroslav 
Published: March 2024

Abstract

An advanced dual-wavelength high-accuracy universal polarimeter was applied to measure optical activity in potassium titanyl phosphate (KTP) nonlinear crystal. Two single-mode He-Ne lasers with close wavelengths of 594 and 633 nm were used as light sources in the experimental setup. Multiple internal reflection of the light was taken into account when processing the results of the polarimetric measurements. Analysis of the optical transmission function for the polarizer-sample-analyzer system and 2D intensity contour maps made it possible to determine the phase parameters, systematic errors, and eigenwaves ellipticity. Gyration tensor component of the KTP crystal is equal to g12 =1.4 · 10-5 which in terms of optical rotatory power corresponds to the value of 2.3 deg/mm.
