Control of Picker-Room Humidity
Authors: Elsas Norman E. 
Published: April 2023

Abstract
This article attempts to deal with the subject in a non-technical manner. The control of the amount of moisture in cotton laps delivered to the card room is highly desirable. Cotton manufacturers desire uniform weights for any given unit of length from the ounces per yard of picker laps to the grains per hank in the final yarn. If laps delivered to the card room contain widely varying percentages of moisture, though a lap scale may indicate identical gross weights, a variation in weight per yard is immediately begun at the cards which must be corrected by gear changes in subsequent operations. By holding picker laps to very close limits as to the net weight of cotton contained for the same number of yards of lap produced, the beginning of evenness or the elimination of variation in subsequent operations is attained.
Improvements in Steels for Wood-Cutting Saws and Knives
Authors: Allen Henry B. 
Published: April 2023

Abstract
The important factors in a review of saw steels are the blade which carries the teeth and the teeth themselves. There is little in sight to promise further marked improvements in the solid-tooth type of saw. The next logical step is to use inserted teeth made from materials known to be well adapted to the function of cutting wood. The same forward step was taken years ago in metal cutting.
Automotive Methods and Practices Involved in Aircraft Engines
Authors: Szekely O. E. 
Published: April 2023

Abstract
The author draws a striking comparison between the cost of standard parts in automobile manufacturing and the cost of parts in airplane manufacturing. Iron and steel and other metals that enter in automobile manufacturing can be secured in the market at apparently a very much lower price than when it is known they are intended for use in airplanes. Although airplane making is a new industry, most of the principles involved in aircraft-engine manufacturing have long been practiced in the internal-combustion engine industry.
Effect of Fouling on Boiler Efficiency
Authors: Pierson J. W. 
Published: April 2023

Abstract
The subject of this paper concerns a situation that confronts those in the Middle West who out of necessity are required to burn some of the low-grade fuels of Illinois.
The fouling conditions incident to the use of such fuel with chain-grate firing with high relative ratings are dealt with. Some of the objectionable characteristics of the fuel not shown by usual analysis are pointed out, together with the severe conditions which soot-blowing equipment of any kind would have to withstand.
The data presented show the efficiency characteristics of an operating cycle with this low-grade fuel compared to that which would exist when using a better fuel. Unfortunately the difficulties of the former cannot be solved by the simple expedient of using a better coal. The choice in such a situation is, then, to operate at high ratings with low overall efficiency or with lower ratings with improved efficiency. Lower ratings, however, would reduce station output, and is not a desirable solution.

Similarity: Limitations in Its Application to Fluid Flow
Authors: Spitzglass J. M. 
Published: April 2023

Abstract
A brief resume of the development of the art for the purpose of bringing about a better understanding of the effects of hydraulic similarity as related to the geometrical similarity of the various devices. Geometrical similarity is of great importance, and devices which are geometrically similar will make the operation more uniform. Geometrical similarity is a matter of construction. Hydraulic similarity is a matter of experiment. Large sizes may or may not show the same results as the smaller ones.
The Kaplan Adjustable-Blade Turbine
Authors: Smith B. E. 
Published: April 2023

Abstract
In this paper the author gives details of construction of the Kaplan adjustable-blade hydraulic turbine, and tells of the advantages obtained by adjusting the blades and the wicket gates simultaneously. This turbine differs from the ordinary wicket-gate turbine in the shape of the top plate and the construction of the runner and shaft. The top plate is shaped so as to form a transition space free from vanes between the wicket gates and the runner, in which the direction of flow of the water is changed from radial to axial. The runner hub carries the movable blades, and the operating connections for moving the blades are inside the single-piece hub casting.
Recent Developments in Blast-Furnace Design and Construction
Authors: McKee Arthur G. , Haven Wm. A. 
Published: April 2023

Abstract
This paper deals with two recent and highly important developments in blast-furnace construction and practice; namely, the trend toward furnaces having daily capacities of 1000 tons or more, and the profitable utilization of blast-furnace gas in the firing of coke ovens, making open-hearth steel, and in the various types of heating furnaces employed in steel mills. These developments have involved certain structural changes in the stacks, which have in time necessitated changes in such auxiliaries as stock-house and blowing equipment, gas cleaners, hot-blast stoves, and boilers. These are all considered in detail by the authors.

A Comparison of Squat Depth and Sex on Knee Kinematics and Muscle Activation
Authors: Barrett Kiara B. , Sievert Zachary A. , Bennett Hunter J. 
Published: April 2023

AbstractThe squat is an essential exercise for strengthening lower body musculature. Although squats are frequently employed to improve lower extremity strength and neuromuscular control, differences between sexes and slight modifications, such as squat depth, can dramatically alter muscle recruitment and thus the foci of the exercise. The purpose of this study was to assess the effect of sex and squat depth on lower extremity coactivation and kinematics. Twenty recreationally active (female = 10) participants were recruited. The first visit consisted of one repetition maximum testing. For the second visit, muscle activation was recorded of the gluteus maximus (GM), semitendinosus, biceps femoris (BF), vastus medialis, vastus lateralis, rectus femoris, and gastrocnemius. Reflective markers were placed on the lower body for three-dimensional motion capture. Participants performed a series of squats to 90 deg knee flexion and 120 deg knee flexion. Benjamin–Hochberg procedure was employed and the alpha level was set at 0.05. Knee flexion (p &lt; 0.001), adduction (p &lt; 0.001), and external rotation (p = 0.008) were reduced during 90 deg compared to deep squats. Hip flexion, abduction, and external rotation were greater in deep squats (p &lt; 0.001). Males had greater hip extensor to quad (HE:Q) cocontraction in 90 deg compared to deep squats (p = 0.007); females produced greater posterior chain activation in deep squats (p = 0.001) on ascent. When comparing sexes, males displayed greater HE:Q in the 90 deg squat during ascent (p = 0.013). The addition of deep squats into a preventative training program could be beneficial in reducing deficits prevalent in females and decrease injury incidence.
Burst Pressure Solutions of Thin and Thick-Walled Cylindrical Vessels
Authors: Zhu Xian-Kui , Wiersma Bruce , Johnson William R. , Sindelar Robert 
Published: April 2023

Abstract
Pressure vessels (PVs) are widely used in the energy industry. Accurate burst pressure is critical to structural design and safe operation for both thin and thick-walled PVs. The traditional strength theories utilized a single-parameter material property, such as the yield stress or the ultimate tensile stress (UTS) to develop failure models for determining the yield or ultimate pressure carrying capacity in the PV design. The UTS-based Barlow formula is a typical burst pressure model developed from the Tresca strength theory that provides the basis for developing regulation rules and failure models for different industry design codes, such as ASME BPVC, ASME B31.3, and ASME B31G, among others. In order to reduce the conservatism of the Tresca strength model, ASME BPVC recently adapted failure models developed from the von Mises strength theory for the PV design and analysis. It has been commonly accepted that the burst pressure of pipelines depends on the UTS and strain hardening exponent, n, of the pipeline steel. An average shear stress yield theory was thus developed, and the Zhu-Leis solution of burst pressure was obtained as a function of UTS and n for thin-walled line pipes. Experiments showed that the Zhu-Leis solution provides an accurate, reliable prediction of burst pressure for defect-free thin-walled pipes. In order to extend the Zhu–Leis solution to thick-walled cylindrical PVs, this paper defined three new flow stresses, modified the traditional strength theories, and obtained three new burst pressure solutions that are valid for both thin and thick-walled cylindrical vessels. The proposed flow stresses are able to describe the tensile strength and the plastic flow response of PVs for a strain hardening steel. The associated strength theories were then developed in terms of the Tresca, von Mises, and Zhu-Leis yield criteria. From these new strength theories, three burst pressure solutions were obtained for thick-walled cylinders, where the von Mises solution is an upper bound prediction, the Tresca solution is a lower bound prediction, and the Zhu-Leis solution is an intermediate prediction of burst pressure for thick-walled cylinders. Finally, the proposed burst pressure solutions were evaluated and validated by two large datasets of full-scale burst tests for thick-walled tubes and for thin-walled pipes.

Published: April 2023

Abstract
Restenosis after stent implantation is a major limitation of revascularization technique. Retrieving the stent safely and smoothly after the vascular remodeling is completed shows important clinical value. In this paper, a novel retrievable peripheral vascular stent and its modified retrieval platform were developed and a finite element analysis (FEA) model was established to study the retrieval process of the stent. Meanwhile, the safety and feasibility of the retrievable stent were assessed through in vivo experiments. The maximum strain of the stent is 6.87% during the whole retrieval process, which is less than the ultimate elastic strain of nitinol alloy. The simulation results indicate that the stent is not damaged during the whole retrieval process. Finally, the stents were implanted into Bama miniature pigs to assess the retrieval process, and the results suggest that the stents can be retrieved successfully within 30 min after implantation, and minor local mechanical injury can be found in the intimal layer of the blood vessel due to the deployment and retrieval of the stent. Studies presented in this work illustrate the feasibility of a novel retrievable peripheral vascular stent, providing an additional avenue to reduce the risk of restenosis.

Published: April 2023

Abstract
A suitable scaffold architecture is always desirable to get a favorable tissue response for bone tissue engineering. In this regard, a fluid-structure interaction analysis was carried out on different porous scaffolds to observe the in vitro mechanical responses due to fluid flow, followed by a submodeling method to obtain the cellular deformation and strain. Different types of scaffolds were designed based on different porosity and architecture. The cell was modelled with cytoplasm, nucleus, cell membrane, and cytoskeletons. The main objective of the study is to examine the variation of cellular responses due to different porosity and architecture of the scaffold. The results of this study highlight that permeability is higher in the case of gyroid structure and wall shear stress (WSS) is higher in the case of diamond structure. The permeability of all scaffolds increases with the increase of porosity. The opposite trend is shown in the case of WSS within scaffolds. The cell is showing higher deformation when it is placed on the front position of the scaffold towards the direction of fluid flow. This study will guide us in predicting an ideal scaffold for better cell growth.

Published: April 2023

BackgroundMedicines optimisation and adherence support are essential to secondary prevention after myocardial infarction (MI). Following successful implementation of a consultant pharmacist-led post-MI medicines optimisation clinic, the service was expanded by training advanced clinical pharmacists to manage clinics (with appropriate multidisciplinary team support).MethodsKey steps in the development process were: definition of a key competency framework based on relevant qualifications and experience, knowledge, skills and clinic management practicalities; creation and enaction of trainee-specific development plans to address gaps (including independent learning, teaching from multidisciplinary colleagues and shadowing in clinics); establishment of relevant protocols and proformas to ensure consistent standards (eg, a patient self-reporting tool for identifying adherence barriers, consultation proforma, directory of clinical parameters and pathway for onward referral when needed); phased clinic roll-out, initially under supervision; and gathering of feedback from patients and colleagues. Clinic letters from 50 attending patients were reviewed to quantify resulting interventions; the first 50 anonymously completed patient feedback questionnaires were also analysed.ResultsExpansion of the service initially doubled capacity. A review of clinic letters from attending patients demonstrated that various interventions were recommended, including further investigations, medication changes, lifestyle adjustments and onward referrals. Most respondents to the patient feedback questionnaire thought the clinic was patient friendly and welcoming (n=48/50; 96%); felt listened to (n=48/50; 96%); considered that adequate explanation was given (n=47/50; 94%); and felt clear plans were provided (n=45/49; 92%). Most agreed that it was valuable (n=44/50; 88%), and the mean rating was 4.48 (on a scale of 1 (very poor) to 5 (excellent)).ConclusionsA person-centred post-MI medicines optimisation service was successfully delivered by appropriately trained advanced cardiology pharmacists. A structured competency framework and training programme were required, but once completed, the clinic was highly valued by patients. A similar model could be rolled out elsewhere with adaption to local requirements.

BackgroundThe optimal duration of dual antiplatelet therapy (DAPT) after stent-assisted coil embolization (SACE) for cerebral aneurysm remains uncertain. This randomized trial of short- versus long-term Dual AntiPlatelet Therapy for Stent-Assisted treatment of CErebral aneurysm (DAPTS ACE) aimed to clarify whether long-term DAPT can reduce the occurrence of ischemic stroke in patients with cerebral aneurysms treated by SACE compared with short-term DAPT.MethodsPatients treated for cerebral aneurysm with SACE were enrolled from 17 hospitals in Japan. Patients were enrolled within 30 days after SACE and assigned in a 1:1 ratio to receive long-term (12 months) or short-term (3 months) DAPT with aspirin and clopidogrel. Randomization was performed centrally through a web-based system. The primary outcome was the time to ischemic stroke event during 3 to 12 months after SACE. This trial was registered with the Japan Registry of Clinical Trials (jRCTs051180141).ResultsA total of 142 patients were recruited from November 4, 2016 to January 7, 2019. Among them, 65 and 68 patients assigned to the long- and short-term DAPT groups, respectively, were included in the full analysis set. Ischemic stroke occurred in no patients in the long-term DAPT group and in one patient in the short-term DAPT group. The incidence rate did not differ between the groups (0.0 vs 2.1/100 person-years; log rank test, P=0.33).ConclusionsIn this multicenter randomized controlled trial, there was not a statistically significant difference in the rate of ischemic strokes between long- and short-term DAPT.

Authors: Eren Nurhan , Tunc Pervin , Yücel Başak 
Published: April 2023

Eating disorders (EDs) affect the physical, psychological, emotional and interpersonal areas of the individual and cause serious medical and mental consequences. Their treatment should be handled in a multidisciplinary manner.The objective of this study was to investigate potential benefits of long-term art-based group therapy (ABGT) as an adjunct to treatment for a variety of EDs. This study examined the effects of ABGT on disease symptoms, difficulty regulating emotions, depression, anxiety, targeted problems, functioning of individuals with EDs and therapeutic efficiency of the group. The study was carried out as a pre-test-post-test, quasi-experimental study with a control group, with a small sample diagnosed with an ED. In addition to their standard treatment at the outpatient centre, participants were included in a 30-week long-term semistructured ABGT focused on raising awareness of their psychological problems. Participants who received ABGT had significantly better functioning and lower severity of target problems compared with the control group. The severity of the three most important problems reported by patients post-ABGT compared with pre-ABGT and the effects of these problems on their social/private lives reduction was observed. The participants mostly benefited from catharsis, universality, self-understanding, existential factors and family re-enactment in the group process. Through the artwork, participants recognised the mental conflicts causing the symptoms of their ED. We found that art-based interventions are useful in the treatment of EDs, as they positively changed the functioning and symptoms of people with EDs. We recommend that clinicians keep these interventions in mind in formulating treatment protocols for these disorders.
Meson excitation time as a probe of holographic critical point
Authors: Hajilou Ali 
Published: April 2023

AbstractWe study the time evolution of expectation value of Wilson loop as a non-local observable in a strongly coupled field theory with a critical point at finite temperature and nonzero chemical potential, which is dual to an asymptotically AdS charged black hole via gauge/gravity duality. Due to inject of energy into the plasma, the temperature and a chemical potential increase to finite values and the plasma experiences an out-of-equilibrium process. By defining meson excitation time $$t_{ex}$$

near the critical point as the system evolves towards the critical point. We observe that by increasing the interquark distance the dynamical critical exponent increases smoothly. Also, we obtain for slow quenches different values of the dynamical critical exponent, although for fast quenches our result for the dynamical critical exponent is in agreement with the one that is reported for studying the quasi-normal modes. Consequently, this indicates that in this model for fast quenches and small values of interquark distances the gauge invariant Wilson loop is a good non-local observable to probe the critical point.
