An investigation on plastic deformation and nanomechanical properties of Cu60Zr40/ Ni80P20 amorphous nanolaminates

This paper aims to investigate the nanomechanical properties of amorphous nanolaminates by using the molecular dynamic (MD) simulation of nanoindentation process. To achieve this goal, two metallic glass (MG) nanolaminates with the arrangement of Cu60Zr40/Ni80P20 (CN type) and Ni80P20/Cu60Zr40 (NC type) were constructed. The MD outcomes unveiled that the NC-type sample exhibited a weaker strength at the loading stage and experienced a sharper relaxation at the end of holding stage. The strain maps of samples also revealed that the plastic deformation in the CN type initiated at the interface of substrate/indenter and was generated into the depth of material with a pear-like shape. On the other hand, the NC-type sample showed an accumulation of strain at the top layer normal to the direction of indenting process. This result indicated that the plasticity evolution occurred with a homogenous mode in the bulk of CN-type nanolaminate.

Quantitative Microbial Risk Assessment of North Carolina Type 2 Reclaimed Water for Agricultural Reuse

As treated wastewater is increasingly used for agricultural purposes; questions remain about the microbiological quality of produce irrigated by these waters. This study conducted a quantitative microbial risk assessment (QMRA) using microbial data collected from North Carolina Type 2 reclaimed waters, which have been proposed as supplemental irrigation waters. Reclaimed waters were collected from four different water reclamation facilities located in central North Carolina and evaluated for five representative pathogens from the three groups of microorganisms (bacteria, virus, and protozoan parasites). Using these data, produce consumption scenarios were evaluated using a variety of irrigation techniques, including spray irrigation, drip irrigation, and subsurface drip irrigation, and the disability adjusted life years (DALYs) that result from illness by each pathogen as a result of produce consumption were compared to the acceptable level set by the World Health Organization. Based on the types of crop irrigation examined in this study using NC Type 2 reclaimed water, there were irrigation conditions and certain pathogens for which the annual risk of infection was not always reduced below the acceptable DALY risk level of <1 × 10−6 set by the WHO. The risks of viral infection by adenoviruses groups A–F were below the acceptable risk level; however, for Salmonella spp., Cryptosporidium, and Giardia, the annual risk of infection was sometimes greater than would be considered acceptable.

A novel thread connection structure of slimehole drilling tool in ultra-deep natural gas well.

The thread connection's root fillet radius of 0.038″ size is the greatest weakness of the API NC type joints and thread. During the slimehole drilling, especially in the deep and ultra-deep gas well, its stress concentration factor and notch sensitivity factor are very high A novel thread connection design (TM) of a drilling tool is proposed to decrease the fatigue failure of the slimehole drilling tool in the deep and the ultra-deep gas well in the Tarim oilfield China. The novelty in the TM thread structure is, reducing the threads per inch, extending the distance from the last engaged thread to the external shoulder of the pin and adding three threads to the conventional connection. The novel thread connection will improve the slimehole drilling tool's anti-fatigue life due to its improved elasticity and rigidity. Furthermore, the TM can transfer the maximum stress at the connection root to the loaded surface, which can effectively lower the fatigue notch's sensitivity coefficient. In this paper, the finite element method (FEM) is applied to carry out the detailed comparative analysis of the TM with existing thread connection NC38, TX60 and TH90. The TM has the lowest stress concentration factor and fatigue notch sensitivity coefficient, so its anti-fatigue life is the highest. In addition, TM is manufactured and is tested at Tarim oilfield in China.

Anatomic Analysis of the Attachment of the Posteroinferior Labrum and Capsule to the Glenoid: A Cadaveric Study

To measure the height of the posteroinferior glenohumeral ligament (PIGHL) attachment to the labrum and the depth of the posteroinferior labrum to the glenoid, macroscopically, and to investigate the morphology of the attachment of the posteroinferior labrum to the glenoid, histologically. Fifty cadaveric shoulders without exposed subchondral bone on the glenoid and detached posterior labrum were used. We examined the frequency of the heights of the PIGHL attachments to the labrum and the length of the labral attachment on the glenoid rim at the 7, 8, 9, and 10 o'clock positions, macroscopically. According to morphology of the histological labral attachments, it was divided into 3 groups. Labra attached on the articular surface and the glenoid neck were defined as the SN type, while labra attached only to the glenoid neck constituted labra attached to the bone and side of the articular cartilage (Nc type) and labra attached only to bone (Nb type). The PIGHL attached from 7 o'clock to 9 o'clock in 48 shoulders (96%). The mean labral attachment at the 7 o'clock position was 6.3 ± 1.0 mm (range, 4.6-9.4 mm), which was significantly longer than at the other positions (P < .05). Histologically, the frequency of SN type attachment was 49 (98%) shoulders at the 7 o'clock position. The PIGHL attached between 7 and 9 o'clock in 96% of the shoulders. In 98% of the shoulders, the labrum did not attach to the articular surface, but attached to both the articular cartilage and the bone of the glenoid neck at 7 o'clock. The posteroinferior labrum should be repaired widely at the 7 o'clock position and not on the articular surface because the labrum attached anatomically to the glenoid neck.

Histological properties of oscillating intracardiac masses associated with cardiac implantable electric devices.

BackgroundThere have been a few cases of echogenic cardiac implantable electric device (CIED) lead‐associated oscillating intracardiac masses (ICMs) in leads imaged by echocardiography. The histological properties of ICMs could help clarify the etiological diagnosis. Although there is extensive literature on mass size, the histological properties of such masses have not been characterized. The aim of this research was to clarify the histological features of oscillating ICMs in CIED patients.MethodsPreoperative echocardiography was performed in all candidates for CIED removal. In the patients with ICMs, specimens were obtained by 3 methods: direct tissue collection during open‐heart surgery; tissue collection together with the CIED lead during transvenous extraction; and tissue collection by catheter vacuum during transvenous CIED removal. A standard histopathological examination of ICM tissue was performed.ResultsA total of 106 patients underwent lead removal in our institute (April 2009‐March 2018); 14 patients had an ICM (13.2%), and 7 specimens were obtained in patients with CIED lead‐related ICM. Following histological examination, 2 types of ICM were identified: one mainly composed of thickened endocardium (EN type; 3 patients), and the other mainly an aggregate of inflammatory cells as a neutrophil cell (NC type; 4 patients).ConclusionsTwo histological types of intracardiac masses, including a thickened endocardium type and a neutrophil cell type, were identified. These classifications might help make an accurate histological diagnosis of lead‐associated intracardiac masses.

Large‐scale atmospheric circulation control of summer extreme hot events over China

AbstractA large‐scale high air temperature event in China during July 2017 is examined using observational reanalysis data. Based on this case study, summer extreme hot events (EHEs) over China are classified into five types using the self‐organizing map (SOM) method. The five EHE types include those over northeast China (NEC type), northwest China (NWC type), north China (NC type), mid‐eastern China (MEC type) and south China (SC type). All types are associated with sustainable anticyclones (EHE anticyclones). Composite analysis shows that the EHE anticyclone in northern China (corresponding to the NEC, NWC and NC types) is primarily formed by downstream wave train propagation from upstream blocking, while EHE anticyclone formation in southern China (corresponding to the MEC and SC types) is driven by the joint action of downstream wave train propagation and westward movement of the western Pacific subtropical high. Moreover, the upstream blocking and downstream EHE anticyclone embedded in the wave train play important roles in maintaining the wave train. The upstream blocking acts as an energy source for downstream EHE anticyclone intensification and leads to EHE formation, with the intensified zonal wind at certain latitudes affecting the wave train propagation direction. This finding indicates that the upstream blocking with intensified zonal wind at certain latitudes may serve as an indicator for the prediction of EHE anticyclones over China. As a consequence of the persistent EHE anticyclone, the land surface is primarily warmed by enhanced shortwave radiation through reduced regional cloud cover. For the NWC and NC types, heating of the lower atmosphere takes place via the sensible heat flux; whereas, for the NEC, MEC and SC types, the main heating terms are the latent heat flux, sensible heat flux and upward longwave radiation.

Genotype-Phenotype Correlation Study and Mutational Analysis in a Chinese Cohort with 21-Hydroxylase Deficiency

Background: Steroid 21-hydroxylase deficiency (21OHD) is the most common enzymatic defect. Genotype-phenotype associations were concluded in different ethnic group. However, such correlations have not been well established in Chinese. This study aimed to analyze this correlation in a Chinese 21OHD cohort and the function of four novel mutations of CYP21A2 gene. Methods: A Chinese 21OHD cohort was enrolled to investigate the clinical, biochemical, and genetic characteristics of this disorder. Symptoms and laboratory findings of all the members were collected. Mutation analysis of CYP21A2 gene, 21-hydroxylase activity assays and in silico predictions of protein structure were performed. Genotype and phenotype associations were analyzed in both the cohort and 487 Chinese CAH patients ever reported. Findings: Among the total cohort, 47 patients (65.3%) were diagnosed as SW phenotype, 11 (15.3%) were SV type and 14 (19.4%) were NC type. Interestingly, the value of FSH and LH for the prediction of the severe SW phenotype was up to 0.862 and 0.669, respectively. Overall, the detection rate of CYP21A2 mutation was 97.9%, which revealed 25 mutations and 36 genotypes. Four novel mutations (p.L199X, p.E321del, p.H393Q and p.L459-P464del) were detected. All these four mutations were predicted to destroy 21-hydroxylase three-dimensional structure and induced a significantly reduced CYP21 activity of less than 5% compared with the wild type. Interpretation: A high consistency of genotype-phenotype association was found in SW CAH and a less matched correlation in SV and NC CAH. Moreover, FSH and LH levels were proved to be a promising marker for predicting the severity of the disease. Funding: This work was supported by grants from the National Natural Science Foundation (No. 81370891 and No. 81670720), Special Funds for Taishan Scholar Project (No. tsqn20161071). Declaration of Interests: The author reports no conflicts of interest in this work. Ethical Approval Statement: This study was approved by the Ethics Committee of the Shandong Provincial Hospital.

Tertiary treatment and dual disinfection to improve microbial quality of reclaimed water for potable and non-potable reuse: A case study of facilities in North Carolina

Treated wastewater is increasingly of interest for either nonpotable purposes, such as agriculture and industrial use, or as source water for drinking water supplies; however, this type of advanced treatment for water supply is not always possible for many low resource settings. As an alternative, multiple barriers of physical, chemical and biological treatment with lower cost and simpler operation and maintenance have been proposed as more globally applicable. One such water reclamation system for both non-potable and potable reuse, is that approved by the State of North Carolina “for Type 2” reclaimed water (NCT2RW). NC Type 2 potable reuse systems consist of a sequence of tertiary treatment to produce well oxidized reclaimed water that is then then further treated by two steps of disinfection, typically UV radiation and chlorination. In this case study, the log10 microbial reduction performance of NCT2RW producing water reclamation facilities is evaluated. Based on the results presented here, NCT2RW consistently achieved high (6 for bacteria, 4 for virus and 4 for protozoan parasite surrogates) log10 reductions using the NC proposed treatment methods. Additionally, lower but significant log10 reduction performance was also documented for protozoan parasites and human enteric viruses.

An audit of setup reproducibility in radiotherapy of head and neck cancers

Background: The use of a customized immobilization thermoplastic mask is essential to compute clinical target volume (CTV) to planning target volume (PTV) margins. Purpose: The purpose of this study was to audit setup reproducibility in head and neck cancers (HNCs) since commencing an intensity modulated radiotherapy (IMRT) program. Patients and Methods: Patients for IMRT of HNC were immobilized using either a plain S type mask (S) or with a customized reenforced support at nasion and chin (S-NC) or an extended U type mask (U- NC), for head (H) and neck (N) regions, following radiotherapy planning contrast-enhanced computed tomography scans used to generate digital reconstructed radiographs (DRRs) at 0° (anteroposterior [A-P]) and 270° (lateral) on which match structures were contoured. Orthogonal MV portal images (PIs), A-P, and lateral were obtained. PIs were matched with the DRRs to obtain the setup variations, and the systemic (∑) and random errors (σ) to calculate PTV margins using the van Herk formula (2.5∑ +0.7σ). Results: Thirty-three patients provided 226 paired PIs with matching done separately for HNC regions. PTV margins for mediolateral, A-P, and craniocaudal directions for the head region were 3, 4, and 5 mm for S; 3, 4, and 3 mm for S-NC; and 3, 2, and 2 mm for extended U- NC type masks, respectively. For neck region, PTV margins were 4, 8, and 5 mm for S; 3, 5, and 3 mm for S-NC; and 4, 5, and 2 mm for extended U- NC type masks. Conclusions: These audits provide the necessary confidence to decrease population-based CTV to PTV margins.

Encapsulation is a significant prognostic factor for better outcome in large hepatocellular carcinoma

The aim of this study was to determine the effect of tumor encapsulation of hepatocellular carcinoma (HCC) on long-term survival. A retrospective review of 1,240 patients who underwent hepatectomy from January 1993 to June 2005 was conducted. There were 891 patients with tumor encapsulation (EC type) and 349 patients without tumor encapsulation (NC type). Clinicopathological factors, surgical outcome, and long-term survival were analyzed. Disease-free survival (DFS) was affected by surgical margin involvement, the presence of surgical complications, vascular invasion, liver cirrhosis, tumor encapsulation, tumor size >5 cm, tumor rupture, and the presence of satellite lesions (all, P < 0.05). Overall survival (OS) was also affected by the same parameters, except for satellite lesions. When the patients were grouped by tumor size >5 or ≤5 cm, the protective effect of encapsulation was only observed when the tumor size was >5 cm [odds ratio (OR) for DFS = 0.75, P = 0.02; OR for OS = 0.68, P < 0.01]. Tumor encapsulation is a significant prognostic factor for HCC >5 cm.

Translation interface modulation in NC-pyrrhotites: Direct imaging by TEM and a model toward understanding partially disordered structural states

The crystallographic complexity of “hexagonal” or “intermediate” pyrrhotites (Fe1-xS with 0.125 > x > 0.080) is a long-standing and challenging problem. Integral (e.g., 5C) and non-integral NC type structures found within this group at ambient temperatures are characterized by sharp but complicated electron diffraction patterns, which were found to be interpretable in terms of a translation interface modulation (TIM) superstructure. Transmission electron microscopy (TEM) dark-field images obtained using superstructure reflections show dense arrangements of stripes, which can be interpreted as arrays of closely spaced anti-phase domain boundaries (APB). The displacement vector at the interface is R = 1/8[001] of a metrically hexagonal 4C superstructure cell and the involved translations are solely confined to the Fe sublattice. The vacancy arrangement of the APB-free monoclinic 4C-pyrrhotite serves as a base of the TIM superstructure and therefore NC structures can be regarded as two super-imposed ordering phenomena relating to the arrangements of individual vacancies and APBs, respectively. APBs are chemically non-conservative and govern the higher Fe/S ratios of intermediate NC-pyrrhotites. If oriented strictly parallel to (001) the APBs can be regarded as completely filled Fe double layers within the 4C stacking sequence. However, direct imaging of APBs shows waviness and variable disorder on mesoscopic scales, yielding essentially aperiodic structures. A high degree of self-organization among APBs has been observed within apparent diffusion profiles around exsolved troilite lamellae and along interfaces with 4C-pyrrhotite, where complicated eightfold node arrangements occur. Our TEM observations indicate that all NC-type pyrrhotites can be treated by the TIM approach and that the concepts of polytypism and polysomatism in pyrrhotite are not fully capable in representing the observed structural complexities.

The Excurrent Ducts of the Testis of the Emu (Dromaius novaehollandiae) and Ostrich (Struthio camelus): Microstereology of the Epididymis and Immunohistochemistry of its Cytoskeletal Systems

The volumetric proportion of the various ducts of the epididymis of the emu and ostrich and the immunohistochemistry of actin microfilaments, as well as cytokeratin, desmin and vimentin intermediate filaments, were studied in the various ducts of the epididymis of the emu and ostrich. The volumetric proportions of various ducts, which are remarkably different from those of members of the Galloanserae monophyly, are as follows: the rete testis, 5.2 +/- 1.4% for the emu and 2.4 +/- 1.8% for the ostrich; efferent ducts, 14.2 +/- 2.3% (emu) and 11.8 +/- 1.8% (ostrich); epididymal duct unit, 25.8 +/- 5.8% (emu) and 26.1 +/- 4.1% (ostrich) and connective tissue and its content, 54.7 +/- 5.8% (emu) and 60.0 +/- 4.9% (ostrich). Unlike in mammals and members of the Galloanserae monophyly, only vimentin was immunohistochemically demonstrated in the rete testis epithelium of the emu, and none of the cytoskeletal protein elements in the ostrich rete testis. The epithelium of the efferent ducts of the emu co-expressed actin, cytokeratin and desmin in the non-ciliated type I cells, and vimentin in the ciliated cell component. The ostrich demonstrated only cytokeratin in this epithelium. The ratite epididymal duct unit is different from that of mammals in lacking actin (only weaky expression in the ostrich), desmin and cytokeratin, and a moderate/strong immunoexpression of vimentin in the basal cells and basal parts of the NC type III cell in the epididymal duct unit. Immunoexpression of the microfilaments and intermediate filaments varied between the two ratite birds, as has been demonstrated previously in birds of the Galloanserae monophyly, and in mammals.

Both Fibrous Capsule Formation and Extracapsular Penetration Are Powerful Predictors of Poor Survival in Human Hepatocellular Carcinoma: A Histological Assessment of 365 Patients in Japan

A new definition of infiltration to the capsule (fc-inf) has been proposed as a novel marker for predicting the prognosis of 88 patients with hepatocellular carcinoma (HCC). The current aim was to present evidence to develop the fibrous capsule and fc-inf, from the Japanese histological findings for HCC, and to validate their biological significances and predictive power of survival in a large series. A total of 365 HCCs were divided into HCCs without the fibrous capsule (NC type; n = 135) and HCCs with the fibrous capsule (FC type; n = 230). Then, FC type was subclassified into two types: extracapsular infiltrating (EC) type (n = 125), in which cancer cells penetrated outside the fibrous capsule, and intracapsular (IC) type (n = 105), in which the infiltrating cancer cells stayed inside the fibrous capsule. The proportion of less histological differentiation and portal venous invasion was higher in FC type than in NC type. The fibrous capsule came to be observed according to the increase of tumor size (P < 0.0001). FC type had significantly poorer outcome for overall survival than NC type (P = 0.0022). EC type showed more intrahepatic metastasis than IC type. The macroscopic subclassifications were significantly affected the presence of fc-inf. EC type had significantly poorer outcome for disease-free survival than IC type (P = 0.0132) and was an independent prognostic factor for disease-free survival (P = 0.0482). Fc-inf defined as extracapsular penetration was verified to be a novel marker for predicting prognosis, and presence of fc-inf might be predicted by tumor gross features.

Content of stabilizer determination results analysis of naturally aged gun propellants

Monitoring of the stabilizer content is one of the modern and reliable methods in the world, and here also, which is used to control chemical stability and to predict the usage time of gun propellants. For the purpose of evaluation of gun propellants' chemical stability manufactured in our country, in this paper -we analyzed results from the content of stabilizer determination in naturally aged single base, NC and NCD type, and double base, NGB and NGH type of gun propellants. At the same time -we analyzed results from both collections of gun propellant samples, one from Kragujevac factory (KB-1) and the other from Zelenika factory (KB-2). Obtained results point that the stability decays faster for KB-2 collection samples, -which can be explained due to climate factors. Beside this influence, obtained results prove the influence of many factors on chemical stability of gun propellants: used components, quality of the ingredients, procedures of manufacture, shape and dimensions of gun propellant grains, etc. .

Correlation of chemical stability estimation results of naturally and accelerated aging gun powders

Monitoring the content of the stabilizer is one of the most reliable and modern methods used all over the world as well as in our country for chemical stability control and shelf life prediction of gun powders. For reliability rating of the used method, there has been examined samples of naturally aged single-based gun powder NC type and double-based gun powder NGB type all manufactured in different years. The samples were taken from explosive ordnance. Reaction rates constants of stabilizer consumption and shelf life of gun powders have been determined. These values were compared to analog results taken for the same gun powders tested 20 years ago. Satisfactory agreement either for naturally or accelerating aging gun powders has been confirmed. Beside that, it was determined that NC gun powder from non hermetic munitions cases proved to be considerably less stable than the originally packed NC gun powder. .

Tensile strength of soldered gold alloy joints

Statement of problem. Little information is available about the mechanical properties of soldered gold alloys after they have undergone various heat treatments. Purpose. This study investigated the influence of heat treating on the strength properties of soldered joints of two gold alloys (NC Type IV and Sofard), which can be age-hardened at intraoral temperature. Material and methods. Dumbbell-shaped specimens were cast with each gold alloy and were cut at the center of the connecting bar for soldering. The two halves of the casting were then soldered with two different gold-based solders (Maingold and Degulor). Three different heat treatments were performed on the soldered gold alloy assemblies: solution heat treatment (ST) at 700° C for 5 minutes (treatment A); aging at 37° C for 7 days after ST (treatment B); and aging at 250° C (Sofard) or 400° C (NC type IV) for 15 minutes after ST (treatment C). The tensile strength, elongation and microhardness were evaluated after each heat treatment. Results. The hardness values of Sofard significantly ( p < 0.05) increased during aging at 37° C (treatment B) and produced adequate strengths of the soldered joints, especially with the harder solder (645.7 MPa: Degulor [222 VHN] vs. 493.3 MPa: Maingold [165 VHN]). Conclusions. The results of this study indicated the possibility of strengthening soldered joints in the oral environment, thus eliminating the necessity for any additional hardening heat treatment.

THE EFFECT OF ENDOGENOUS TSH-SUPPRESSION THERAPY

This investigation was undertaken to clarify the effectiveness of endogenous TSH-suppression therapy with thyroxin (T4) for adenomatous goiter (AG) employing ultrasonography. Seventeen AG patients treated with T4 (50-100μg daily) during the past 7 years were enrolled in the present study. Serum TSH level of the all patients were continuously suppressed under 0.2μU/ml. Sixteen patients with AG only being followed-up periodically without suppression therapy during the same period, were served as control for the purpose of comparison. Ultrasonographical examination was carried out every 3-6 months. According to the change in the size of main thyroid nodule, all these patients were classified into 3 types as follows: D; apparent decrease more than 5mm in diameter of the nodule, I; increase of the nodule size more than 5mm, and NC; no significant change in diameter of the nodule. In the 17 patients having the TSH-suppression therapy with T4, D-type, I-type and NC type were noted in 3, 4 and 10 patients, respectively. Meanwhile, in the 16 control patients, three types were found in 3, 6, and 7 patients, respectively. There exist no significant differences in change of the main nodule size between the two groups. This clinical study indicates that endogenous TSH-suppression therapy for AG would not be effective.

Columnare und nematische Phasen neuer makrodiscotischer Materialien [1

AbstractThe first radially multi(biphenylethinyl) substituted arenes possessing benzene or naphthalene cycles as molecular centers as well as Palladium atoms containing macrocyclic complexes derived from hexaalkoxy substituted aldobisimines by cyclopalladation have been synthesized and investigated by physical methods. Most of these flat compounds with molecular core diameters ≧24 Å and molecular weights up to 4000 are novel thermotropic liquid crystals, in part highly unsaturated or metallomesogens in structure, respectively, exhibiting columnar and/or nematic phases. Sterical influences on the mesophase formation of these spacious molecules are discussed as well as interesting changes of their properties by variation of their self‐organization occurring in binary systems. Thus, addition of an electron acceptor, for example 2,4,7‐trinitrofluorenone, leads to the formation of charge transfer complexes, mesophase stabilizations or even to inductions of other mesophases including nematic ones of the ND or NC type. Dissolving such thermotropic columnar mesogens in various organic solvents gives rise to lyomesomorphism; in case of at least one of the palladomesogens a transition between two different lyotropic nematic phases (N1 and N2) has been observed.
