Published: July 2022

CHEMCAD process simulator was used for the analysis of existing HF stripping column in LAB plant(Arab Detergent company/Baji-Iraq). Simulated column performance curves were constructed, The variables considered in this study are the thermodynamic model option, top and bottom temperatures, feed temperature, & feed composition, Also simulated columns profiles for the temperature, vapor and liquid flow rates and compositions, were constructed, using different thermodynamic models options, Four different thermodynamic models options (SRK, TSRK, PR, and ESSO) were used, affecting the results within l-25% variation for the most cases, The simulated results show that about 5% of paraffin (C10 & C11) presents at the top stream which may cause a problem in the LAB production plant, The major variations were noticed for the total top vapor flow rate with bottom temperature and with feed composition. The column profiles maintain fairly constants for tray 5 (immediately below feed) through tray 18 (immediately above reboiler). These tfays can be removed without severely affected thecolumn profile. Simulation of the HF stripping column in LAB production plant using CHEMCAD simulator, confirms the real plant operation data, The study gives evidence about a successful simuiation with CHEMCAD’

In this research, a numerical study has been done to done to clarify the effect of the eccentric annulus of to two horizontal cylinders on the rate flow the behavior of the thermal boundary layer at the entrance. The research includes the study of the effect of the eccentric annulus percentage and its directions on the flow behavior when the internal cylinder. The theoretical analysis of the question includes the solving of Naver – Stoke and energy equations on the supposition that the flow is steady, fully developing hydrodynamic, and in the stage of thermal developing. The question has been numerically solved after the transformation of the Cartesian coordinates to the computational domain by applying body fitted coordinates. The results include a survey of the cylinder surface in many sites of annulus flow, where as it is appeared in that the bouncy force causes the secondary flow behaves none uniformly at the entrance. The Nusselt number average along the two cylinders is decreased with the increase of eccentricity as a result of narrowing in the flow area which diminishes the average of heat transfer quality. We also conclude that the increase of Rayleih number with the movement of the heated cylinder towards low causes the increase of the average of Rayleih number and the laminar flow changes to turbulent flow at the limited region of the entrance when Rayleih number increases or the eccentricity percentage with cylinder movement away from the perpendicular halfway axis but the disturbance vanishes in approaching to the fully developed heated region. A correlation relationship is extracted to find an average change of Nusselt number after the stability of flow in the fully developed region when the diameter of the internal cylinder equals to half of external.

Published: July 2022

A theoretical study was carried out for transient heat transfer forced convection through horizontal tube filled with porous media. All the properties of the porous media are assumed to be constant in both the radial and axial directions. The governing equations are momentum and energy equation. These were formulated in using polar coordinates system. The results obtained are for three values of the effective Prandtl numbers and dimensionless pressure gradients. Theses gradient are (0.1,0.3,0.9) Pre ,(103 ,104 ,105 )B. The study proved that the thickness of the thermal boundary layer and its length depend on the parameter (B) and the effective Prandtl number. The thickness of the thermal boundary layer began with an increase starting from the front edge (inter section) until the thickness becomes equal to the radius of tube. The increase in Prandtl number gives an increase in the thickness of the thermal boundary layer for the same pressure gradient.

Published: July 2022

In this research, an empirical study has been done to find fouling factor for water flowing inside air-cooled plate finned radiator with constant heat flux beside the boundary condition of the thermal process. The research also required practical tests for finite period time(twenty days for each test). Two kinds of treated water that used in cooling towers was used to show the agreement between calculated fouling factor and this treatment. The work required test specific radiator in the beginning to calculate a design fouling factor that compared with others results with keeping the operation conditions constant. A simulation computer program required to enters all the boundary conditions for the heat system besides the correlating equations for the heat transfer of the radiator. The results show a good inspection for the fouling factor that agrees the practical analysis for the water treatment.
Geographical approach to determining access to justice in criminal cases (on the example of district courts of the Kurgan region)
Authors: Abdulvaliev Almaz Firzyarovich 
Published: July 2022

The purpose of this study is to test the extent to which courts of general jurisdiction in some regions of the Russian Federation are accessible to the population from a geographical point of view. The object of the study was the district courts of general jurisdiction located in the district centers of the Kurgan region, and their remoteness from the locations of local governments, law enforcement agencies, airports, bus stations and railway stations. The main research methods were the geoinformation method, the cartographic method, as well as the comparative legal method, including the analysis of the norms of the criminal procedure legislation of the Russian Federation and judicial practice. The application of the geographical approach made it possible to establish in various aspects how accessible the courts of general jurisdiction are to the population living in various municipal districts of the Kurgan region. The conducted research revealed a number of problems related to ensuring access to justice for the local population. Despite the fact that most of the district courts of general jurisdiction in municipal districts are located within walking distance from local self-government and law enforcement bodies nearby in the district center and have good transport links with bus stations, railway stations and air terminals, yet 1/10 of the district courts remain inaccessible to the population due to remoteness and lack of good and permanent transport communication. In addition, the underdeveloped air communication of the Kurgan region with other regions of Russia does not contribute to ensuring high-quality access to justice.

Published: July 2022

Objective To explore the person-level predictors of adherence to a step count intervention following total knee replacement (TKR). Design Prospective cohort study, nested within the PATHway trial. Methods Participants who had recently undergone TKR were recruited from 3 rehabilitation hospitals in Sydney, Australia, for the main trial. Only data from participants who were randomized to the TKR intervention group were analyzed. Participants in the intervention group (n = 51) received a wearable tracker to monitor the number of steps taken per day. Step count adherence was objectively measured at 3 months as the number of steps completed divided by the number prescribed and multiplied by 100 to express adherence as a percentage. Participants were classified into 4 groups: withdrawal, low adherence (0%–79%), adherent (80%–100%), and >100% adherent. Ordinal logistic regression was used to identify which factors predicted adherence to the prescribed step count. Results Of the 51 participants enrolled, nine (18% of 51) withdrew from the study before 3 months. Half of participants were classified as >100% adherent (n = 24%, 47%). Ten were classified as low adherence (20%), and 8 participants were classified as adherent (16%). In the univariable model, lower age (OR 0.90; 95% CI 0.83–0.97), higher patient activation (OR 1.03; 95% CI 1.00–1.06), and higher technology self-efficacy (OR 1.03; 95% CI 1.00–1.06) were associated with higher adherence. After adjusting for age in the multivariable model, patient activation and technology self-efficacy were not significant. Conclusion Younger age, higher patient activation, and higher technology self-efficacy were associated with higher adherence to a step count intervention following TKR in the univariable model. Patient activation and technology self-efficacy were not associated with higher adherence following adjustment for age. J Orthop Sports Phys Ther 2022;52(9):620–629.

Background:
Congenital muscular torticollis (CMT) is a common musculoskeletal anomaly that can be excellently managed at birth with conservative physiotherapy; as a result, literature on neglected cases of CMT in older patients is sparse, and there is controversy regarding the ideal surgical approach. This report aims to provide the outcome of 28 adolescent patients with neglected CMT who underwent unipolar release at the distal sternocleidomastoid muscle (SCM).

Methods:
Twenty-eight adolescent patients with untreated CMT presented to our department between 2016 and 2019 and underwent unipolar release at the distal end of their SCM. All patients had no other anomaly based on clinical examination and radiological investigations. At the time of surgery, the mean age of patients was 15.8 years (range 13–18 years). There were 10 male and 18 female patients with the right side affected in 20 cases. All patients were followed up for 2 years. Patients were evaluated using an adapted version of the modified Lee’s scoring system to assess cosmesis and the cervical-mandibular angle (CMA) to assess radiological change.

Results:
The adapted modified Lee’s scoring system indicated 17 patients (60.7%) had an excellent outcome, 6 patients (21.4%) had a good outcome, and 5 patients (17.9%) had a fair outcome. In particular, scarring was fine in 23 patients (82.1%) and only slight in the remaining. Independent to the categorical outcome, all patients subjectively reported high satisfaction with their cosmesis. The preoperative mean CMA was 19.6° (range, 8.5–31.5°), which was reduced to a mean of CMA of 14.0° (range, 3–28°) after surgery (P < 0.05). No patient developed any permanent complication or required surgery for recurrence. No serious postoperative complications such as infection or hematoma were observed.

Conclusion:
In uncomplicated cases of neglected CMT in adolescent patients, unipolar tenotomy of the distal SCM is a safe and reliable technique with good clinical outcomes.

Authors: Hawsawi Aysha Hamzah , Bawazir Minyal , Basindwah Sarah A. , Alqurashi Ashwag , Ajlan Abdulrazag 
Published: July 2022

Background:
Primary jugular fossa meningiomas are one of the rarest subgroups of meningioma, with an estimated incidence of 0.7–4.3% of all skull base meningiomas. Indeed, only 145 cases of jugular foramen meningiomas have been reported in the literature to date. While meningiomas of this region are typically referred to as “jugular foramen meningiomas,” we make a distinction between meningiomas arising directly from the foramen itself, and those arising from the jugular tubercle. Jugular tubercle meningiomas, therefore, represent an even smaller subset of an already uncommon location for meningiomas. The jugular tubercle is the upper surface of the lateral parts of occipital bone presents an oval eminence, which overlies the hypoglossal canal and is sometimes crossed by an oblique groove for the glossopharyngeal, vagus, and accessory nerves. Only eight cases in the anterior foramen magnum lesions excised by a far lateral retrosigmoid approach have been described. The aim of this video article is to describe the surgical approach the senior author used to access lesion involving the jugular tubercle.

Case Description:
In this surgical video, we present a case of a 56-year-old female presented to our hospital with dizziness, headache, lower cranial nerves deficits, and lower limbs weakness. On exam, she was noted to have a left paraparesis, 9th, 10th, and 11th nerves palsies. An MRI scan demonstrated a mass in the region of the left jugular tubercle. Frozen section was suggestive of meningioma and our patient underwent a successful near total resection with no permanent neurologic sequelae.

Conclusion:
Jugular tubercle meningiomas are one of the rarest subgroups of meningioma. The described modified retrosigmoid approach provides outstanding access to the entire ventrolateral brainstem and cerebellopontine angle, with reduced approach related morbidity.

Authors: Tirado-Ornelas Héctor Alonso , Olivares-Peña Jorge Luis , Olivares-Camacho Jorge Luis , Santos-Franco Jorge Arturo , Ochoa-González Maurilio Vicente 
Published: July 2022

Background:
Hemangioblastomas are benign tumors that develop in the central nervous system. They represent 1.5–2.5% of all intracranial tumors, and about 2–15% of all spinal cord tumors. They are highly associated with von Hippel–Lindau disease.

Case Description:
A 36-year-old female presented with a 4-year history of progressive right upper extremity distal weakness and cervical pain. The magnetic resonance imaging demonstrated a homogeneously, contrast enhancing intradural/intramedullary tumor at C6–C7 with perilesional edema and a syrinx accompanied by a cerebellar cyst with a mural nodule. Surgery included excision of the spinal lesion and decompression and excision of the cerebellar cyst and mural nodule (i.e., median suboccipital craniectomy and cervical C5–C7 laminectomy).

Conclusion:
Surgery is the gold standard treatment for symptomatic hemangioblastomas, and surgical approaches should minimize risk.

Published: July 2022

Background:
Systemic anticoagulation has been the standard treatment for cerebral venous sinus thrombosis (CVT). Although endovascular treatments, including mechanical thrombectomy (MT), have been reported to be effective for CVT, no clear evidence has been established.

Case Description:
A 51-year-old woman who had been administered oral contraceptive pills was transferred to our hospital with altered consciousness and disorientation. Computed tomography (CT) revealed a hyperdense signal in the straight sinus (StS), and CT angiography revealed a defect in the basal vein and StS, leading to a diagnosis of StS thrombosis. Although systemic anticoagulation through unfractionated heparin was performed, her neurological condition deteriorated, and venous ischemia was observed on CT the next day. She then underwent MT. Partial recanalization was achieved with an aspiration catheter and a stent retriever. Her neurological condition improved tremendously, and venous ischemia was reversed following MT. She was discharged 3 weeks later without neurological deficits with oral anticoagulant.

Conclusion:
This was a relatively rare case with CVT confined to StS. Immediate combined MT for StS thrombosis can improve venous circulation, make the venous ischemia reversible, and improve patient outcomes, even if it results in partial recanalization.
Pour une histoire de la pensée russe : les continuités à l’époque soviétique
Authors: Tihanov Galin 
Published: July 2022

Cet article étudie les continuités qui se font jour, souvent cachées par des changements politiques dramatiques, sur la scène de la philosophie et de la pensée sociale pendant la période soviétique, depuis la Révolution d’Octobre en 1917 jusqu’à la désintégration de l’URSS en 1991. Comme le paradigme intellectuel dominant de toute cette période était le marxisme, toute réflexion sérieuse sur la question de la continuité doit non seulement prendre en compte le marxisme, mais encore le mettre au centre de l’attention. C’est ce dont traite la première partie de l’article. Dans cette optique, la continuité inscrite dans la dialectique permanence / transformation avait deux aspects importants : l’auto-conscience et le positionnement du marxisme soviétique par rapport à la philosophie occidentale non- marxiste, et, au-delà, mais aussi indépendamment, à la pensée russe d’avant 1917.La seconde partie de l’article examine différents discours de l’exceptionnalisme, essentiellement la renaissance du slavophilisme, du počvenničestvo et de l’eurasisme. L’accent est mis sur l’Union Soviétique et non sur l’émigration, car cela aurait reproduit l’idée erronée que les intellectuels émigrés sont les seuls hérities authentiques de la tradition prérévolutionnaire.
