Labib, Emad L.,Mo, Y.L.,Hsu, Thomas T.C. Korea Concrete Institute 2013 International Journal of Concrete Structures and M Vol.7 No.1

Prestressed concrete (PC) is the predominant material in highway bridge construction. The use of high-strength concrete has gained wide acceptance in the PC industry. The main target in the highway industry is to increase the durability and the life-span of bridges. Cracking of elements is one aspect which affects durability. Recently, nine 7.62 meter long PC I-beams made with different concrete strength were designed according to a simple, semi-empirical equation developed at the University of Houston (UH) (Laskar et al., ACI Journal 107(3): 330-339, 2010). The UH Method is a function of shear span-to-depth ratio (a/d), concrete strength $\sqrt{f^{\prime}_c}$, web area $b_wd$, and amount of transverse steel. Based on testing these girders, the shear cracking strength of girders with different concrete strength and different shear span-to-depth ratio was investigated and compared to the available approaches in current codes such as ACI 318-11 (2011) and AASHTO LRFD Specifications (2010).

Labib, E.,Omar, E.,Tag-El-Din, A.E.,Nour, A.M. Asian Australasian Association of Animal Productio 1994 Animal Bioscience Vol.7 No.2

Two experiments were conducted to study the effect of using Egyptian mallow leaf meal (EMLM) on growth performance and feed utilization of common carp (Cyprinus carpio L.) in experiment 1. Four diets containing 0, 5, 15 and 25% EMLM were included at the expense of berseem leaf meal and fed to fingerlings of common carp for 98 days. The results showed that the average daily gain, feed intake and feed coefficient ratio (FCR) were improved (p<0.05) with increasing the level of EMLM in the diet. Fish fed 25% EMLM were similar to control fish (30% berseem leaf meal) in the productive value (PPV%). In experiment 2, five diets were prepared to contain: 1) 30% berseem leaf meal, 2) 25% untreated EMLM, 3) 25% cooked EMLM 4) 25% treated EMLM with 0.5% NaOH and 5) 25% treated EMLM with 1% NaOH. The results showed that diet containing EMLM gave the best growth performance and feed utilization. However, diet containing 1% NaOH treated EMLM superior to the other diets in PPV% and energy utilization. Diets containing 0.5% NaOH-treated EMLM or cooked EMLM decreased the protein utilization compared to those containing EMLM.

Mechanical vapor compressor is a part of steam compressor employed in multi effect distillation process. A greater understanding of flow phenomena inside of mechanical compressor plays an important role when the performance improvement of overall system in MED desalination is necessary. In this paper, the mechanical compressor was numerically investigated to study the influence of operating condition. The steady numerical simulation using k- ε turbulent model with frozen rotor interface was used for multistage centrifugal compressor simulation. In this simulation using three section zones and only single passage on each stage is considered to reduce the computational cost and time consuming. This study is just only focused on the influence of operating pressure. From the simulation result shows a good understanding about the optimum operating condition even though using steady simulation.

Thomas Brendon Russell,Peter Lawrence Zaki Labib,Somaiah Aroori 한국간담췌외과학회 2023 Annals of hepato-biliary-pancreatic surgery Vol.27 No.1

Backgrounds/Aims: The aim of this study was to describe short- and long-term outcomes of patients who underwent pancreatoduodenectomy (PD) at a typical United Kingdom hepatopancreatobiliary unit. Methods: A retrospective analysis of all PD patients with histologically-confirmed pancreatic ductal adenocarcinoma (PDAC), ampullary adenocarcinoma (AA), or distal cholangiocarcinoma (CC) from September 1st, 2006 to May 31st, 2015 was carried out. The following information was obtained: demographics, comorbidities, preoperative investigations, neoadjuvant treatment, operative details, postoperative management, complications, adjuvant treatment, five-year recurrence, and five-year survival. Effects of selected preoperative variables on short- and long-term outcomes were investigated. Results: Of 271 included patients, 57.9% had PDAC, 25.8% had AA, and 16.2% had CC. In total, 67.9% experienced morbidity and 17.3% developed a Clavien-Dindo grade ≥ III complication. The 90-day mortality was 3.3%. Clinically-relevant postoperative pancreatic fistula, bile leak, gastrojejunal leak, postpancreatectomy haemorrhage and delayed gastric emptying affected 8.1%, 4.1%, 0.0%, 9.2%, and 19.9% of patients, respectively. American Society of Anesthesiologists grade III–VI correlated with overall morbidity (p = 0.002) and major morbidity (p = 0.009), but not 90-day mortality or five-year survival. The same pattern was observed in patients with a preoperative serum bilirubin > 29 μmol/L and/or a neutrophil/lymphocyte ratio > 3.1. Five-year cancer recurrence and five-year survival were 68.3% and 22.5%, respectively. PDAC patients had higher five-year recurrence but lower five-year survival rates (both p = 0.001). Conclusions: In our series, the majority of patients experienced a complication. However, few patients experienced major morbidity. Surgical risk factors did not affect five-year survival.

Significance of the Association between Disc Degeneration Changes on Imaging and Low Back Pain: A Review Article

Ahmad Jabir Rahyussalim,Muhammad Luqman Labib Zufar,Tri Kurniawati 대한척추외과학회 2020 Asian Spine Journal Vol.14 No.2

Low back pain (LBP) is a major health issue resulting in a huge economic burden on the community. It not only increases the medical costs directly, but also raises the disability and loss of productivity in the general population. Symptoms include local pain over the spinal area, pain radiating to the lower leg, stiffness, and muscle tension. LBP is strongly linked with intervertebral disc degeneration that is further associated with the disruption of the complex anatomy of nucleus pulposus, annulus fibrosus, and adjacent supporting structures of the spine. Change in the shape and intensity of nucleus pulposus, decreased disc height, disc herniation, vertebral endplate changes, presence of osteophyte, and posterior high intensity zones are degenerative changes found in imaging studies. Every feature is considered while grading the severity score. Modic changes, DEBIT (disc extension beyond interspace) score, and Pfirrmann criteria are some of the scoring criteria used for evaluating disc degeneration severity. Moreover, the total number and contiguous pattern of affected discs play a crucial role in symptom generation of back pain. Many studies have reported asymptomatic patients. Thus, the correlation between degeneration severity found in imaging study and symptom severity of LBP remain unclear. This review discusses and summarizes the available literature on the significance of the association between the severity of degenerative changes found in imaging study with the presence and intensity of LBP.

Do some patients receive unnecessary parenteral nutrition after pancreatoduodenectomy? Results from an international multicentre study

Thomas B. Russell,Peter L. Labib,Paula Murphy,Fabio Ausania,Elizabeth Pando,Keith J. Roberts,Ambareen Kausar,Vasileios K. Mavroeidis,Gabriele Marangoni,Sarah C. Thomasset,Adam E. Frampton,Pavlos Lykou 한국간담췌외과학회 2024 Annals of hepato-biliary-pancreatic surgery Vol.28 No.1

Backgrounds/Aims: After pancreatoduodenectomy (PD), an early oral diet is recommended; however, the postoperative nutritional management of PD patients is known to be highly variable, with some centers still routinely providing parenteral nutrition (PN). Some patients who receive PN experience clinically significant complications, underscoring its judicious use. Using a large cohort, this study aimed to determine the proportion of PD patients who received postoperative nutritional support (NS), describe the nature of this support, and investigate whether receiving PN correlated with adverse perioperative outcomes. Methods: Data were extracted from the Recurrence After Whipple’s study, a retrospective multicenter study of PD outcomes. Results: In total, 1,323 patients (89%) had data on their postoperative NS status available. Of these, 45% received postoperative NS, which was “enteral only,” “parenteral only,” and “enteral and parenteral” in 44%, 35%, and 21% of cases, respectively. Body mass index < 18.5 kg/m2 (p = 0.03), absence of preoperative biliary stenting (p = 0.009), and serum albumin < 36 g/L (p = 0.009) all correlated with receiving postoperative NS. Among those who did not develop a serious postoperative complication, i.e., those who had a relatively uneventful recovery, 20% received PN. Conclusions: A considerable number of patients who had an uneventful recovery received PN. PN is not without risk, and should be reserved for those who are unable to take an oral diet. PD patients should undergo pre- and postoperative assessment by nutrition professionals to ensure they are managed appropriately, and to optimize perioperative outcomes.

The Energy Saving Effects of Complex Heat - Integrated Distillation Configurations

Yoon, En Sup,Zaki, Magdi Labib 한국화학공학회 1989 NICE Vol.7 No.4

The distillation of a ternary BTX mixture was studied to evaluate three potential energy saving methods: optimal configuration structuring, heat integration and heat pumping. Ten heuristics, in two categories, were induced and arranged in order of priority. Separation-technique heuristics: (1) Favor heat flux exchange between units by direct stream contact (thermal coupling). (2) Favor separations with initial splits between extremes in volatility (prefractionation). (3) Favor heat integration if flexibility and operability are satisfactory. (4) Favor operation under lower pressures if the cost involved is reasonable. (5) Favor heat pumping with a product stream as the working medium. Separation-system heuristics: (1) Favor the PET configuration. (2) Favor the PF configuration if various feeds are anticipated. (3) Favor the SS configuration for very low concentrations of the most or least volatile components. (4) Favor the R heat integration form. (5) Favor the OHP heat pumping form.
