An Integrated Network Modeling Framework for Analysis of Multi-line Order Pick Systems

Due to demanding service levels in E-commerce order fulfillment, modeling and analysis of order picking processes in warehouses deserve special attention. With a particular focus on multi-line E-commerce orders, we develop modeling tools that are necessary to analyze the order consolidation delays in the downstream pick stations. We develop a queuing network modeling framework for integrated analysis of upstream (storage system) and downstream (pick system). We apply our modeling approach to an integrated order-pick system that includes a shuttle-based storage and retrieval system, and a single pick station. Using simulations, we test the effect of the storage system configuration on the order throughput time

Submissive Osteoarthrectomy in Temporomandibular Joint Ankylosis- Subharti Experience

Objective: The purpose of this study is to assess the effectiveness of submissive osteoarthrectomy in temporomandibular  ankylosis patients.Patients and method: A total 15 patients (20 joints) were operated under general anaesthesia and in these 15 patients 5 were male and 10 were female. Out of these 15 patients 10 were suffering from unilateral TMJ ankylosis and 5 were with bilateral TMJ ankylosis. The age of the patients was ranged from 10-19 years with mean of 12.53 years. After exposure ankylotic mass a gap of 6mm was created to achieve the satisfactory mouth opening followed by interposing the temporalis myofacial flap and pedicled buccal fat pad between the cut ends of the bone.Result: All the patients were followed post-surgery for a minimum duration of 24 months. The mean post-operative mouth opening of the patients was 32.45 mm after 2 years with significant improvement in contralateral excursive and protrusive movements. In this case series no significant sign of heterotrophic calcification or reankylosis was noted and anatomical shape of the condyle was also achieved in all cases.Conclusion: Submissive osteoarthrectomy is a modification in surgical technique for the release of temporomandibular joint ankylosis has considerable results in terms of functional and esthetic outcome

On-Line measurement and mathematical modeling of fiber properties during the melt spinning and melt blowing processes /

The on-line measurements during the melt spinning process were used to quantitatively evaluate the effect of molecular orientation (caused due to threadline stress) on the crystallization rate of polymers.An on-line experimental study of the melt spinning and melt blowing polymer fiber forming processes was performed. During melt spinning, the fiber properties measured included fiber diameter, temperature, velocity, birefringence, density, and crystallinity. In order to determine the fiber density, a novel technique using the continuity equation, in conjunction with the measured diameter and polymer mass flowrate, was developed. Heretofore, the fiber density has never been measured on-line during fiber forming processes. The fiber crystallinity was then determined from the measured density using a mixing rule. The measurements made during the melt blowing process included fiber diameter and temperature. The on-line measurements during melt blowing were compared with the Uyttendaele-Shambaugh mathematical model for melt blowing.Also developed was a mathematical model for the melt blowing process. This model is a 3-dimensional, logical extension of the 2-dimensional Rao-Shambaugh model for melt blowing. The utility of this model lies in the simulation of melt blowing from the slot melt blowing dies (e.g., an Exxon die). The useful information predicted from the model includes fiber diameter, temperature, threadline stress, and fiber motion

Influence of Pederson Score and its Constitutional Anatomical Parameters to Predict the Postoperative morbidity after Lower Third Molar Removal: A Prospective Cohort Study

The purpose of present study is to determine the Influence of Pederson Score and its constitutional anatomical parameters in predicting the postoperative morbidityafter the removal of impacted lower third molars. This clinical prospective cohort study included 50 patients with impacted mandibular third molars. Their position, depth and angulation was assessed using Intraoral Periapical and Orthopantomograms and  subsequently all molars were assigned as easy, moderate or difficult to extract as per Pedersons difficulty index.  Swelling, Trismus and Pain and Incidence of Alveolar Osteitis (AO) were evaluated preoperatively and postoperatively at 24, 48, 72 and 7 days. Difficulty Score predicted the Trismus (all follow-ups) and Pain at 72 hrs and at 7 days postoperatively. Mild group of Pederson scale did not depict the swelling as mild group revealed more swelling compared to moderate group. Ramus relation was not predictive of any complications significantly. Relative depth of third molars significantly predicted postoperative swelling (p-value=0.00). Angulation of the third molars significantly affected development of trismus (p-value=0.03). Incidence of AO was influenced by Ramus relation and Relative depth of third molar. Our experience showed that it is difficult to estimate actual morbidity by difficulty index/anatomic variables only and the demographic and clinical variables should not be ignored

Immediate placement of dental implants in non vascularised iliac graft after resection of anterior mandible : A case report

This case report presents a combination of surgical and prosthetic rehabilitation applied to a case in postsurgical reconstructed mandible. We report a patient suffering from desmoplastic ameloblastoma of mandible, who underwent Enbloc resection and reconstruction with iliac bone graft with simultaneous placement of dental implant in anterior mandible. Two dental implants were placed at both ends of the graft. At five years follow up, favourable osseointegration with healthy peri-implant tissue was reported

Correlation between CT phenotypic patterns with clinical, nutritional and pulmonary function parameters among COPD patients

Background: COPD is a multi-dimensional disorder with multiple phenotypes. The commonly used GOLD guidelines and Spirometry do not fully reflect the heterogeneous nature of the disease, structural abnormalities, and phenotypes. This necessitates CT phenotyping because of difference in treatment strategies, disease progression and response to treatment.Methods: We conducted our study on 40 male COPD subjects aged more than 45 years, divided them into 4 groups based on CT phenotype as normal, Airway Dominant (AD), Emphysema Dominant (ED) and mixed types.  We compared the clinical parameters, spirometry indices, markers of nutrition (including BMI) across these phenotypes. CT phenotypes were determined by Low Attenuation Area (LAA) and Wall area.Results: In our study, 16 (40%) had airway dominant (AD), 15 (37.5%) had emphysema dominant (ED), 4 (10%) had mixed, and 5 (12.5%) had normal CT phenotype.  The various nutrition indicators like height, weight, BMI, fat-free mass index was not statistically significant. The difference in the median FEV1/FVC across CT phenotypes was statistically significant (P Value 0.002). The difference in Haemoglobin, Total protein, Albumin, Triglycerides and Total Cholesterol was not statistically significant across CT Phenotypes.Conclusions: The GOLD guidelines do not fully reflect the heterogeneous nature of the disease which necessitates CT phenotyping. In our study, there was a significant association between BMI, FEV1/FVC ratio with CT phenotypes. Identifying the different phenotypes of COPD will allow us to implement a more personalized treatment and choose the best treatment option
