For a Prosopography of Athenian Priests and Priestesses in the Imperial Age: Preliminary Notes

This paper offers an overview of an ongoing research project on priesthoods in Roman Athens, whose first purpose is to realise a prosopography of the Athenian cult personnel during the Roman imperial period (c. 27 BC-267 AD). Despite a growing interest in the last years on the social aspects of Greek (and Roman) religion and specifically on priesthoods as is also shown by the publication of several collective volumes on the latter subject, systematic investigations on the cult personnel of single poleis are still lacking. As regards Athens, in particular, while there are studies on specific priesthoods such as the Eleusinian priesthoods or the priests of Asklepios, to date there is no comprehensive investigation on the Athenian cult personnel. Furthermore, while different aspects connected with priesthood have been studied for Classical and Hellenistic Athens, the Roman imperial period has been left largely ‘in the shadows’. Having this in mind, I have begun a research on Athenian cult personnel during the Roman imperial period. Since any such investigation must be based on a systematic collection of the epigraphic evidence on the individual holders of the different priesthoods, my first aim is to realise a prosopography of all religious functionaries, both male and female, of Athenian cults (that is to say of cults performed in Athens) from Augustus up to the 3rd c. AD (ca. AD 267). The prosopography is to be followed in due time by a synthesis on the religious, social, and cultural aspects of priesthood in Roman Athens. The prosopographic catalogue, collecting the relevant epigraphic and literary testimonies, will provide for each priest the main data (name, chronology, status, other charges, bibliography) and a thorough commentary on his family relations and on his priestly activity and public career.

The growing importance of achieving national self-sufficiency in immunoglobulin in Italy. The emergence of a national imperative.

Since the inception of industrial plasma fractionation during the Second World War, a succession of protein therapies isolated from plasma have determined the volume of plasma requiring collection, and have also shaped the economics of the industry. These so-called plasma drivers have successively included albumin, coagulation Factor VIII (FVIII) and, for the past thirty years, intravenously (IV) and subcutaneously (SC) administered immunoglobulin (IG) solutions. The sale of IG underpins the profitability of the industry and has experienced continuous growth over the past decades, as the result of growing clinical demand. Modelling this demand using decision analysis indicates that supplying the evidence-based indications for IG therapies will generate a need for IG which exceeds the current plasma collection capacity of most countries. A notable exception to this situation is the United States (US) of America, whose population of compensated plasma donors generates two thirds of the global supply of plasma for fractionation. The US is also the leading consumer of IG, and its health care providers pay the highest price for the product globally. Shortages of IG occur whenever the demand for the product outstrips the supply. Current shortages, following other historical periods of shortage, threaten the well-being of patients dependant on these products and incur heavy costs on health systems. In Italy, the national blood system, which is based on voluntary unpaid donors, reflects a policy of national self-sufficiency in blood-derived therapies (a strategic objective of the national blood system itself), based on solidarity as an ethical principle. This system has increased the collection of plasma for fractionation by 3.8% per annum over 2008-2017, in accordance to a plan for plasma procurement targeting a collection rate of 14.1 L of plasma per thousand (103) population by 2020. Over the same period, IG usage has increased by 8.5/per annum, to 89.2 g IG/103 population. In this paper, we review the factors which, increasingly, are causing an imbalance between the global supply and demand for IG, and we assess Italy's capacity to ensure that increasing this level of independence is no longer simply an ethical, but also an economic imperative, with implications for the security of Italy's health system.

Introduction: The New England Town Meeting: A Founding Myth of American Democracy

Notwithstanding notable exceptions, historical investigation is far from central in deliberative scholarship and even recent work on participatory research stresses the need for more historical work. The aim of our introduction to this collective volume is to assess and to draw attention to the contribution of historical analysis in the current scholarly debate on democracy, in particular regarding the ways in which participation and deliberation emerge and develop in New England’s famous town meetings. Town meetings have traditionally been cited as one of the fullest and earliest realizations of the idea of democratic government and of deliberation at work. Nowadays the great debate on deliberative and participatory democracy has contributed to restoring the town meetings as a symbol of democratic deliberation. The critical study of how one of the oldest and most inspiring forms of democratic participation has evolved is not only a fascinating endeavor in itself, it is also a unique opportunity to better understand how and to what extent these institutional practices, inspired by ideals of deliberation and participation, can support – or impede – the democratization of today’s societies.

Simulator Development for Radial Artery Gasometry Collection

Introduction - The collection of arterial gasometry is a common procedure, mainly in inpatient setting (1). Thus, analysing and monitoring arterial blood gas play an important role in diagnosing and managing health conditions (2). The development of a simulator can help professionals improving radial artery gasometry collection. However, there are a number of high cost simulators which may turns the learning difficult (3). Mainly in public Universities, which lack enough resources and financing, in low and middle-income countries, the sources for high cost simulators may be impeditive. It is responsibility of the institutions that still cares about students’ formation to develop low costs solutions that could be copied as example for any other university in the same situation. In this setting, we aimed to develop a low costs simulators prototype that could be manufactured for any other institution. The first project was the gasometry collection simulator in radial artery. Usually, the gasometry is responsibility of a resident. Therefore, it is essential the resident previous training to perform the procedure in the best way before a real situation. The objective of this project was the development of a gasometry collection simulator in radial artery and a training protocol for undergraduate students and resident physicians. Methods - The industrial silicon is an easy manipulation and low-cost material and, therefore, it was chosen for simulate a hand and wrist. The silicone was moulded in a common procedure latex glove. It was used a nº 10 silicon nasoenteral catheter to simulate artery because it mimics the diameter of an adult real radial artery and allows multiple punctures, turning the device more durable. An assistant performed intermittent pressure to a 20 mL syringe coupled to the catheter to simulate the arterial pulse, both in inspection and palpation. The simulation scene was prepared as a clinical case where the examined resident was asked to perform a radial artery gasometry collection. The checklist evaluated the resident attitude (presentation, procedure explanation for the patient and permission asking to proceed), the choice of necessary material, Allen’s test description, and finally the gasometry collection by use of the simulator. During the procedure, all the parameters necessary to the puncture were evaluated, such as pulse palpation, puncture site and angle, collection volume, compression after taking off the needle, and bandage. Results - Five standardized simulators were manufactured, at a cost of 25€ each one, for a pilot study. Experienced professionals tested and approved all models before authorizing the use in a large scale with undergraduate medical students (interns). It was evaluated 107 interns from 5th year of graduation, 55% male. In a first test, only 40% of 107 interns performed Allen’s test before the gasometry collection, 65% chose correctly the necessary material for the procedure, and 72% performed correctly the puncture in the simulator. Conclusion - The development and manufacture of the gasometry collection simulator for procedure in the radial artery is feasible at a reasonable cost (25 € each). The use of simulation may improve medical education in the means that allow the repetition without a patient risk and does not have to be expensive (4).

Introduction: The Promise and Perils of Innovation in Cross-Border Procurement

This is the introductory chapter to a collective volume, Joint Public Procurement and Innovation: Lessons Across Borders (G. M. Racca – C. R. Yukins, eds.) (Bruylant, 2019), vol. 27 of the Administrative Law/Droit Administratif Collection (Director: Jean-Bernard Auby). Innovation is essential for sustainable and inclusive growth in an increasingly globalized economy. To achieve that potential, both the promises and perils of innovation must be investigated, including the risks and opportunities of joint procurement across borders. This in-depth research by a range of procurement experts investigates innovation in public procurement from three different perspectives. First, leading academics and practitioners assess the purchase of innovation, with a particular focus on public contracting for “smart cities,” with a view to meta-infrastructures, public-private partnership arrangements and “smart” contracts. A second line of inquiry looks for ways to encourage innovative suppliers. Here, the collected authors draw on emerging lessons from the United States and Europe, to explore the costs and benefits of spurring innovation through procurement. A third perspective looks to various innovations in the procurement process itself, with a focus on the effects of joint and cross-border procurement in both the European Union and the United States. These chapters review new technologies and platforms, the increasingly automated means of selecting suppliers, and the related efficiencies that “big data” can bring to public procurement. Expanding on research in the editors’ prior volume, Integrity and Efficiency in Sustainable Public Contracts: Balancing Corruption Concerns in Public Procurement Internationally (Bruylant 2014), this volume builds on a series of academic conferences and exchanges to address these issues from sophisticated academic, institutional and practical perspectives, and to point the way to future research on contractual models that are emerging from new procurement technologies.

Optimal collecting policy for apheresis platelets in a regional blood center.

Planning platelet collection and inventory must rely not only on adequate forecasts of transfusion demand but also sophisticated mathematical modeling techniques. This research aims to develop a better demand forecasting model of apheresis platelets and a mathematical programming model to determine the best target amounts of apheresis platelet collection. Time series data of apheresis platelets collected from donors and platelets supplied to hospitals daily in Taipei Blood Center from January 2014 to December 2015 was used to fit a forecasting model which combines a regression-type model for formulating the deterministic trends and seasonal variation and an autoregressive moving average model (ARMA) for explaining remaining serial correlations. A seasonal autoregressive integrated moving average (SARIMA) model was also used for benchmarking the prediction performance. A linear programming model was then formulated to solve for the optimal daily target collection volumes that maximize the total social benefits. The time series model achieved good predictive power with a mean absolute percentage error less than 10%. The appropriateness of the proposed target collection volumes was also verified by using a simulation model, and the proportion of the total platelets requested by hospitals that can be filled by collected apheresis platelets can increase significantly by using the new policy. The methods proposed in this study can be easily implemented to enhance the management efficiency of blood collecting and supplying of a blood center, and to decrease the costs of the blood outdates and shortages.

Peripheral Blood to Marrow Collection White Cell Count Ratio As an Indicator of Harvest Quality and Transplant Outcomes in G-CSF-Primed Marrow Grafts

Background: G-CSF-primed bone marrow (G-BM) is used in some centers as the product of choice in related donor transplants because of lower rates of GVHD and fast engraftment (Morton 2001; Deotare et al. 2015). Marrow collections substantially diluted with peripheral blood may, however, compromise the GVHD-sparing effect of G-BM. Concerns over the variability in the quality of bone marrow harvest have been reported (Spitzer et al. 1994; Prokopishyn et al. 2019). We explored the role of a simple novel quality indicator, i.e peripheral blood to marrow harvest WBC ratio, as a predictor of GVHD risk. Materials and methods: We analysed 156 successive bone marrow harvests for patients suffering from severe thalassemia using G-BM donated by fully matched (10/10 or 12/12) related donors (143 siblings and 13 mothers) at Sankalp-People Tree Centre for Paediatric BMT - Bangalore (80 patients) and Sankalp-CIMS Centre for Paediatric BMT - Ahmedabad (76 patients). G-CSF priming was done for 5 days before the transplant with 10 mcg/kg/day in 2 divided subcutaneous doses and peripheral counts were obtained within 24 hours of collection. G-BM was collected in bags with 20 ml 50 U/ml heparin for the first 200 ml and further 10ml/100ml of marrow. We defined quality of marrow as follows: Quality of Marrow = WBC count of G-CSF primed BM / Peripheral WBC count of donor Quality of Marrow < 0.9 was categorised as poor as it signifies that the concentration of WBCs in bone marrow is same or lesser than the pre-harvest peripheral counts. EBMT criteria was used for grading GVHD. We calculated the odds of aGVHD based upon the quality of marrow. Beside marrow quality, the sex of the recipient seemed to impact GVHD rates and thus regression analysis was used to study the impact of G-BM quality independent of other factors. Statistics were performed on R software (version 3.5.x). Mann Whitney and Fisher's exact tests were used to compare numeric and categorical data respectively. Results: Of the 156 harvests, 18 had poor marrow quality; 33% (6 of 18) of these developed acute GVHD grade II-IV as opposed to 9% (13 of 138) (see Figure 1). Between those who developed GVHD and those who did not, marrow quality (p=0.012), patient sex (p=0.006) and sex mismatch status (p=0.014) were significantly different. Differences in total cell dose (p=0.65), transplant centre (p=0.62), bone marrow cell count (p=0.14) and peripheral cell count before harvest (p=0.72), donor age at BMT (p=0.42), relationship with the donor (p=1.0) and average volume of marrow per draw of syringe (p=0.23) showed no statistical significance. Variables with significant difference (sex mismatch and bone marrow quality) were entered in the Cox's proportional hazards model for acute GVHD II-IV which showed that poor marrow quality is the most significant independent risk associated with a hazard ratio of 3.6 (p=0.009), followed by male to male transplants which were associated with a hazard ratio of 10.6 (p=0.03) See Table 1. Further, poor quality marrow was associated with lower cell count in marrow (p<0.001), higher peripheral counts (p<0.001), higher collection volume (p=0.035) and was seen more in one centre compared to the other (p<0.001). Donor age (p=0.81), donor's relationship (p=1.0), donor sex (0.62), donor's carrier status (p=0.64), donor weight (p=0.85) and average volume of marrow per draw of syringe (p= 0.76) were not statistically significant. Discussion: The role of tolerance induced by mesenchymal stem cells in reduction (Aggarwal 2005) and even the treatment of GVHD (Le Blanc et al. 2004; Baron and Storb 2012) has been reported elsewhere and supports our findings though this is yet to be established (Fisher et al. 2019). Simple quality control of BM could be highly beneficial in all settings in minimising acute GVHD. This is particularly important in low- and middle-income countries where GVHD can be very challenging (Saleem et al. 2018) and is associated with high costs of management and prolonged hospitalisation (Grubb et al. 2016). Our indicator is accurately measurable, inexpensive, precise and timely; further it does not involve any sophisticated equipment (flow cytometry for CD counts), thus may be widely applicable and usable. Conclusion: Quality of BM harvest, as indicated by PB to BM WBC ratio, is a simple, effective and inexpensive informative indicator in the context of G-BM. Poorer quality of marrow collection may be contributing to increased risk of acute GVHD. Disclosures No relevant conflicts of interest to declare.

Evaluation of Dried Blood Spot Sampling for Clinical Metabolomics: Effects of Different Papers and Sample Storage Stability.

The dried blood spot (DBS) sampling has a lot of advantages in comparison with the “standard” venous blood collecting, such as small collection volume, painless and easy sample collection with minimal training required, stable and transportable at ambient temperatures, etc. The aim of this study was to determine the comparability of four different types of DBS sampling (HemaSpot™-HF Blood Collection Device, Whatman® 903 Protein Saver Snap Apart Card, card ImmunoHealth™, and glass fiber strip ImmunoHealth™) for analysis of the global metabolites profile. All the samples were collected from the same person at the same time and stored at room temperature for four weeks in order to exclude all possible deviations deriving from biological variances and to evaluate sample storage stability. Metabolome profiling by direct injection of a deproteinized capillary blood DBS sample into an electrospray ion source of a hybrid quadrupole time-of-flight mass spectrometer was used. Differences in the metabolomics profile were found between the different DBS collection materials, especially for ImmunoHealth™ card and ImmunoHealth™ glass fiber strip. However, our results indicate that the analytical performance of all tested DBS sampling materials showed consistent results overall detected metabolites and no dramatic changes between them in the metabolic composition during the storage time.

TCAD simulation studies of novel geometries for CZT ring-drift detectors

In this work, technology computer-aided design (TCAD) simulation results of new CZT ring-drift detector geometries are presented. The physics model was developed and validated against the results from an existing device which had been comprehensively characterised at x-ray wavelengths. The model was then applied to new detector geometries and a systematic study of the parameters influencing charge collection performed. A comparison between one- two- and three-ring circle and semi-rectangular (or squircle) geometries is presented. In was found that charge collection with the squircle ring configuration was systematically better than the circular configuration and extends approximately m further from the collecting anode. In addition, a two-ring geometry device is shown to collect charge m and m further from the anode when compared to one- and three- ring geometries, respectively. Based on these results, we derive an optimum configuration which potentially can be multiplied on larger crystals, offering an increased charge collection volume without compromising energy resolution.

The group of decorative chrysanthemums includes 21 varieties.

Depth-resolved fiber photometry with a single tapered optical fiber implant.

Fiber photometry is increasingly utilized to monitor fluorescent sensors of neural activity in the brain. However, most implementations are based on flat-cleaved optical fibers that can only interface with shallow tissue volumes adjacent to the fiber. We exploit modal properties of tapered optical fibers (TFs) to enable light collection over an extent of up to 2 mm of tissue and multisite photometry along the taper. Using a single TF, we simultaneously observed distinct dopamine transients in dorsal and ventral striatum in freely moving mice performing a simple, operant conditioning task. Collection volumes from TFs can also be engineered in both shape and size by microstructuring the nonplanar surface of the taper, to optically target multiple sites not only in the deep brain but, in general, in any biological system or organ in which light collection is beneficial but challenging because of light scattering and absorption.

34 Natural History of Pancreatic Fluid Collections in Acute Pancreatitis

INTRODUCTION: Pancreatic fluid collections (PFCs) resulting from acute pancreatitis (AP) can be associated with infections and mass effect. The aim of this study was to evaluate the natural history of PFCs in AP. METHODS: In this study, we so far included 65 patients with PFCs retrospectively (presented to the Pancreas clinic with a history of AP) and 44 prospectively (hospitalized patients). In this abstract, we will present data on only the retrospectively enrolled patients. Patients underwent a thorough demographic and clinical history. We also recorded PFC morphology, presence of venous thrombosis and need for interventions at baseline and each follow-up visit. RESULTS: The mean (SD) age of the patients was 36.45 ± 13.49 years with 58 (89.2%) males. The etiology included alcohol in 26 (40%), smoking in 5 (7.6%), cholelithiasis in 5 (7.6%), and idiopathic in 29 (44.6%) patients. 63 (96.9%) patients had moderately severe while 2 (3%) had severe disease. At presentation, the first episode of AP was seen in 22 (33.8%), recurrent in 27 (41.5%) and acute on chronic in 16 (24.6). The type of fluid collections included APFC in 7 (10.8%), ANC in 5 (7.7%), pseudocyst in 4 (6.2%) and WOPN in 49 (75.4%). During the first 3 months, the mean volume of fluid collections was 326.4 ± 637.3 and venous thrombosis developed in 21 (32.3%) patients. 17 (26.1%) patients required interventions in the first 3 months while 5 (7.7%) in the next 3 months. Venous thrombosis developed in 8 (12.3%) additional patients during the next 3 months. Overall, the most common intervention was EUS guided cystogastrostomy (CG) with SEMS placement in 7 (10.6%), followed by PCD in 6 (9.2%), surgical CG in 5 (7.7%), EUS guided plastic stent placement in 1 (1.5%) and combined procedures in 3 (4.6%). Among patients not undergoing intervention during the first 3months, spontaneous complete resolution was seen in 13 (20%) patients, while a reduction and increase in size was seen in 18 (27.6%) and 17 (26.2%) patients respectively. Among the patients who did not undergo intervention between 3rd to 6th months, complete resolution was observed in 36 (55.4%) patient, while a decrease and increase in size were seen in 11 (16.9%) and 9 (13.8%) patients respectively. Among the patients who underwent interventions during the first and next 3 months, relapse/increase in PFC size was seen in 4 (6.2%) and 2 (3.1%) patients respectively. CONCLUSION: 3/4th of PFCs undergo spontaneous resolution within 6 months while most relapses and venous thrombosis occur within the first 3 months.

Ionization Chambers to Determine Neutron and Gamma-Ray Kerma in a Research Reactor

Ionization chambers were designed and constructed to determine the kerma rates in various materials within several centimeters of a Training, Research, Isotopes, General Atomics (TRIGA) reactor core operating at 1 MW. The primary aim of this article was to compare kerma measurements with the advanced Monte Carlo code calculations of nuclear heating. Wall thickness, collection gap, and fill gas pressure were chosen to satisfy Bragg–Gray criteria, so that the measured ionization current was related to the kerma rate in the wall material. Chamber wall materials composed of low mass number elements, including hydrogen-rich C552 air-equivalent plastic and beryllium, were selected to measure the kerma due to fast neutron elastic scattering. By operating these neutron sensitive chambers coincidentally with relatively neutron insensitive chambers composed of aluminum and Zircaloy-4, we were able to measure the total heating due to fast neutrons and gamma rays in a material and to differentiate these heating components. A chamber composed of borated stainless steel was used in a similar fashion to measure the thermal neutron flux. The total kerma rate was also measured in various materials typically found in a reactor core. Chamber collection volumes were initially determined using ambient air fill gas and National Institute of Standards and Technology (NIST)-traceable air-kerma rates from a 60Co source. All chambers were sealed with argon gas to provide thermal and compositional stability. Chamber properties, including stability, saturation, and gas-phase mass subject to charge collection, were determined using the 60Co source. Chambers were operated for approximately 30 min adjacent to the reactor core, and the integrity of gas seals was subsequently verified by repeating the measurement with the 60Co source.

Cyberbullying Response System on SNS

The system is designed to search for cyberbullying-related data and to respond by phase to the cyberbullying on the basis of the data authenticity. In particular, each analyzed data is used for D/B for follow-up cyberbullying data authenticity identification and is stored in D/B for follow-up cyberbullying response, therefore preliminary cyberbullying crime signs will rapidly detect and ultimately, its consequent crime damage will be minimized. In terms of data collection and analysis, the proposed model collects cyberbullying data widely present in various forms, while the previous only collects limited data on Twitter. To complement another limitation of the previous, not being able to analyze video, image and freeform letters, the proposal utilizes SNA to analyze bullying data in freeform letter, image and abstract vocabulary. Furthermore, the existing model does not have DB for follow-up utilities, the proposed model applied a DB for follow-ups for more effective operations of cyberbullying data authenticity identification and response module. Cyberbullying crime response method has also been enhanced in its effectiveness, by enabling phased countermeasures, and storing and analyzing the processed result from response module, to respond to future cyberbullying. Consequently, the proposed model is designed to minimize probable victimized damages by improving effectiveness of rapid and accurate phased measures – via data collection and analysis module, expert system, knowledge-based database, D/B1 for follow-up cyberbullying data authenticity identification, crime response module and D/B2 for follow-up cyberbullying response. The proposed Cyberbullying Response System on SNS enabled an enlarged volume and variety of SNS data collection, compared to the previous model, utilized SNA for analysis, enhanced preliminary prediction accuracy to future cyberbullying and allowed more rapid and adequate phased crime response against it – thus, crime damage from cyberbullying is expected to be minimized

Collaborative collection effort strategies based on the “Internet + recycling” business model

“Internet + recycling”, a new and emerging collecting mode, is booming in conjunction with widespread Internet use in China. For the recycling of waste electrical and electronic equipment (WEEE), this paper studies collaborative collection effort strategies in a collection system consisting of a third-party and an e-tailer based on the “Internet + recycling” business model. Considering the collaboration occurring during collecting and selling and mutual influences of partners on the recycling of old products, the paper applies collection effort cost sharing mechanisms to promote recycling. Four models, namely, the centralized model (C-Model), unit transfer price model (P-Model), unilateral cost sharing model (U-Model) and bilateral cost sharing model (B-Model), are established, and optimal decisions and members' profits in various collaborative models are derived and compared. The results show that there exists an interval of profit sharing proportions in which each of the two cost sharing models is a Pareto improvement of the P-Model, and the total collection volume and profit of the collecting system increase in the B-Model relative to those in the U-Model under the same proportion of profit sharing. However, the B-Model is not necessarily a Pareto improvement of the U-Model. The results also show that profit improvements of both parties can be achieved without the third-party sharing the e-tailer's collection effort cost in the B-Model when the collaborative marginal profit is large enough. The paper further explores the impact of the collaborative marginal profit and third-party's market influence on the total collection volume and the efficiency of the collecting system. This study provides insight into the promotion of WEEE recycling and into the selection of collaborative strategies for Internet recycling enterprises. The work will prove beneficial to the development of the WEEE “Internet + recycling” industry.

Conceptual and Simulated Semi-Automatic Urban Waste Management System using Global Systems for Mobile Communication and Customer Reliability Indices

: Municipal Solid Waste Management (MSWM) poses great challenges to many cities around the world. The challenges are fuelled by population explosions all over the world, especially in the major urban centres, against the backdrop of limited resources to manage wastes efficiently. In this paper, a conceptual and simulated semi-automatic approach to MSWM is considered using the prevalent Global Systems for Mobile Communication (GSM) technology to engage both the waste generators and collectors. This system connects users into a central database where data about their waste bin levels are harnessed. Users are prompted via GSM handsets daily for the level of the waste bin. Waste Collection Vehicles are routed based on the responses while an updatable Reporting Reliability Index (RRI) is computed for each user based on estimate of actual level of waste collected as against the reported level to factor future reporting. With history of collection volume at a location known, forecast is made as to the generated waste level when a customer’s response to prompt is not available. The system is tested on a simulated 30-node housing estate and two dump sites with vehicles routed to optimize distance covered and volume of waste collected. Customers report when prompted with 0, 1, 2, 3, 4 for waste levels ranging from empty to full bin fills. Vehicles are routed to collect wastes at locations with a minimum threshold level of 2. Results obtained showed statistically insignificant differences in distribution of means of collection distance covered weekly but 13.31 volume units/km collected with this method compared with 3.08 volume units/km run of fixed routing scheme, at = 0.05. The cost saving potential and environmental benefits of timely waste disposal of this scheme is thus demonstrable.Keywords: Municipal Solid Waste, Waste Management, SMS Gateway, GSM, Reporting Reliability Index.
