Abstract:
PURPOSE: To establish an experimental model of laparoscopic partial nephrectomy (LPN) in rats and to analyze morphological alterations in the renal parenchyma utilizing an electric cautery and harmonic scalpel. METHODS: Forty Wistar rats were used, divided in 2 experiments with 20 rats each: experiment I, LPN was performed with an electric cautery and the rats were subdivided into groups A and B; experiment II, LPN was performed with a harmonic scalpel and they were subdivided into groups C and D. The animals in groups A and C were sacrificed shortly after surgery and the remnant kidney was removed to study the following variables: necroses and degeneration. In groups B and D a laparatomy was performed for retrieval of the remnant kidney on the 14th day after surgery to analyze fibrous scarring. RESULTS: For the variables necroses and fibrous scarring, the electric cautery creates, on average, greater width than that produced by the harmonic scalpel (p=0.0002 and p=0.0068 respectively). Regarding the variable of degeneration, we found no significant difference between the two types of scalpels (p=0.1267). CONCLUSIONS: LPN in rats is an adequate and feasible experimental model. The electric cautery caused greater damage to remnant renal tissue when compared to harmonic scalpel.

Abstract:
Introduction: Breast cancer is a major public health problem in the world. Amongthe multidisciplinary approach of surgery, chemotherapy, radiotherapy andhormonal therapy, Modified Radical Mastectomy (MRM) is the most commonsurgery performed to treat breast cancer wherein use of thermal energy hasbeen associated with seroma formation, increased blood loss, wound infection,flap necrosis, hematoma, and prolonged axillary drainage. Harmonic scalpelis an emerging alternative where high frequency mechanical vibrations allowcutting and coagulation at the same time causing little thermal injury. In thisstudy, we compared the outcome between use of harmonic scalpel andelectrocautery in modified radical mastectomy. Methods: A prospective comparative study was conducted at a tertiary carecentre of Nepal from November 2018 to October 2019.A total of 30 patientswere randomized into harmonic scalpel and electrocautery group andcompared in terms of seroma formation, operative time, amount of blood loss,total drain volume, total duration of drain, and post-operative pain. Results: The patients in harmonic scalpel group had significantly less amountof seroma formation (13.3% vs 46%, p=0.046), intraoperative blood loss (150 vs200 ml, p=0.026), total drain volume (483.33 ± 107.718 vs 636.33 ± 239.620ml,p=0.032),total duration of drain requirement(8.73 ±1.907 vs12.13± 4.121, p= 0.007)and post-operative pain (p=0.002). However, operative time (p=0.20) andsurgical site infection (p=0.14) was not significant. Conclusions: Harmonic scalpel has better surgical outcome than electrocauteryin terms of intraoperative blood loss, total drainage volume, total durationof drain and postoperative pain without change in operative time. We thusrecommend preferential use of harmonic scalpel in MRM.

Abstract Introduction Hemorrhoidal disease is an anorectal condition commonly encountered in the clinical practice. Various instruments, such as circular staplers, harmonic scalpels, lasers, and bipolar electrothermal devices, are used in different modalities of hemorrhoidectomy in cases of high-grade hemorrhoids. Objective T compare the results of hemorrhoidectomy using the Ferguson technique and the harmonic scalpel. Materials and Methods The present is a randomized prospective study involving 60 patients submitted to hemorrhoidectomy from February 2022 to January 2024. The patients were randomly grouped: group I was composed of 30 patients who underwent the operation through the conventional Ferguson technique, and group II was composed of 30 patients submitted to hemorrhoidectomy with the use of the harmonic scalpel. Results The demographic and clinical features of the patients in the two groups were identical. We found a significant difference in the mean operative time: for the Ferguson technique, it was of 21.9 ± 4.6 minutes, while for the harmonic scalpel, it was of 17.9 ± 3.1 minutes (p = 0.003). The mean postoperative pain scores on the Visual Analog Scale (VAS) were of 7.1 ± 1.2 points for group I, and of 6.5 ± 0.5 points for group II (p = 0.024). And the mean hospital stay was of 1.23 ± 2.1 days for group I, and of 1.03 ± 0.1 for group II (p = 0.023). No statistical significance was observed regarding the other parameters. Conclusion Hemorrhoidectomy using the harmonic scalpel seems to be a superior approach to treat high-grade hemorrhoids; it has the advantage of reduced hospital stay, decreased postoperative pain, and shorter operative time.

Abstract:
Objectives The harmonic scalpel cuts and coagulates simultaneously using a mechanical vibration. We present our 1-year experience in the use Harmonic ACE(tm), Harmonic FOCUS(tm) and harmonic scalpel with 5 mm curved blade in head and neck surgery (Ethicon Endo-Surgery). Methods Over period of 1 year we performed 295 thyroidectomies, 23 parotidectomies, and 45 tonsillectomies using the harmonic scalpel. Control group consisted of 106 thyroidectomies, 9 parotidectomies, and 30 tonsillectomies that were performed over previous 5 months with the use of conventional hemostatic techniques (electrocautery and knot tying). Results The use of the harmonic scalpel shortened the duration of thyroid and parotid surgery by 20–30% as compared with the conventional techniques (p<0.05). The average skin incision length for those undergoing thyroidectomy with the harmonic scalpel was 1.8 cm shorter as compared with the conventional thyroidectomy group (p<0.05). Because of small skin incisions in thyroidectomy we preferred Harmonic ACE(tm) over Harmonic FOCUS(tm) due to longer shaft of scalpel, while Harmonic FOCUS(tm) was more suitable for parotidectomy. The use of Harmonic ACE(tm) shortened average duration of tonsillectomy by 5.5 minutes, while use of 5 mm curved blade (HF 105) did not affect significantly the average duration of tonsillectomy. Postoperative pain and complication rate were comparable for both groups (p>0.05). Conclusions The use of the harmonic scalpel reduces surgical time and intraoperative blood loss in head and neck procedures, and enables shorter incision length in thyroid surgery.

Abstract:
OBJECTIVE: The purpose of this report was to evaluate the technical benefits, if any, of thyroidectomy using the harmonic scalpel versus conventional thyroidectomy. STUDY DESIGN: One hundred five consecutive patients underwent thyroidectomy over 1 year with use of the harmonic scalpel. They were compared with a group of 20 patients who underwent thyroidectomy 1 year earlier using conventional techniques. RESULTS: The incision length for those undergoing thyroidectomy with the harmonic knife averaged 4.5 cm compared with 5.5 cm for the conventional thyroidectomy group. The operating time for a hemithyroidectomy averaged 50 minutes for the harmonic scalpel group versus 80 minutes for the conventional technique. The operating time for a total thyroidectomy averaged 80 minutes for the harmonic scalpel group versus 120 minutes for the conventional thyroidectomy group. CONCLUSION: The use of the harmonic scalpel in thyroid surgery offers several advantages over the conventional technique. The incision length is shorter and the operating time is reduced. Bleeding is negligible and complications are few. SIGNIFICANCE: The harmonic scalpel, whose use was pioneered in laparoscopic surgery, offers the thyroid surgeon the ability to safely and expeditiously control the feeding vessels through a limited field.

Abstract:
ABSTRACT In this prospective study of 43 patients, 20 patients were operated by the outpatient harmonic scalpel tonsillectomy. The outpatient harmonic scalpel technique was performed by local injection with 2% Xylocaine with 1:80,000 adrenaline solution around palatine tonsils and using harmonic scalpel for dissecting tissue at superior pole until inferior pole of tonsil. Harmonic scalpel will cut and stop bleeding simultaneously and then, using plain catgut 3-0 ligation at the inferior pole of tonsil stops bleeding from tonsil branch of facial artery. All of the patients were followed up for 1 and 3 weeks postoperatively; 19 of 20 (95%) patients who were operated by the outpatient harmonic scalpel tonsillectomy felt satisfied and in one case, the patients wound healing delayed for 3 weeks. All patients were discharged on the day of admission with no major complication. Twenty-three patients were operated by the traditional tonsillectomy as an inpatient. Twenty of 23 (87%) patients were satisfied and in three cases, the patients had delayed wound healing for 3 weeks. The results of the study conclude that the outpatient harmonic scalpel tonsillectomy is satisfactory and medical treatment cost also is cheaper than the traditional tonsillectomy for the majority of patients.

Abstract:
Background: The study aimed to compare the management of Grade III hemorrhoids by conventional Milligan Morgan versus Harmonic scalpel hemorrhoidectomy with respect to the intraoperative time, intra operative blood loss, length of hospital stays, postoperative outcome based on immediate and late complications and activity resumption, recurrence and cost.Methods: In this prospective study, a total of 60 patients, 30 patients undergoing Harmonic Scalpel hemorrhoidectomy and 30 patients undergoing Milligan Morgan hemorrhoidectomy, were studied. Operated patients were monitored for bleeding, pain, retention of urine, fecal incontinence ambulatory time and recurrence.Results: Symptoms such as pain during defecation, bleeding PR were significantly reduced at follow up in patients undergoing Harmonic scalpel hemorrhoidectomy over Milligan Morgan technique. Fecal incontinence was present in 8 cases following Milligan Morgan method over 3 months follow up. Recurrence was highest in (26.08%) in Milligan Morgan group while lowest in (4.34%) in Harmonic Scalpel group. No of days absent from work is more Milligan Morgan group and significantly less in Harmonic Scalpel group.Conclusions: This study showed significant difference in operative time, blood loss during surgery and pain score on postoperative days 15, 1 month, 3 months and 6 months and postoperative analgesic requirement for Harmonic scalpel assisted hemorrhoidectomy as compared to conventional Milligan Morgan, which were statistically significant. Harmonic scalpel hemorrhoidectomy is a newer, safer, more effective, faster and bloodless operative technique with minimal tissue damage and further larger sample studies and required to establish its complete efficacy and benefit over other modalities of hemorrhoidectomy.

Abstract:
AbstractThe objective of this study was to evaluate and compare laparoscopic pyloromyotomy methods involving the laparoscopic scalpel and the harmonic scalpel in pigs. The experiment was conducted on 4 subgroups of 12 animals subjected to laparoscopic-assisted pyloromyotomy with a surgical scalpel and the harmonic scalpel, as well as laparoscopic pyloromyotomy with Berci's laparoscopic scalpel and the harmonic scalpel. No postsurgical complications were observed. Four weeks after the surgery, the animals were sacrificed and autopsy was performed. In one animal peritoneal adhesions between the intestines and the mini-laparotomy incision were found. Laparoscopic pyloromyotomy and laparoscopic-assisted pyloromyotomy performed in pigs enabled the selection of laparoscopic entry sites, instruments for pyloromyotomy and evaluation of the applied surgical procedures in animals. The results of this study indicate that the methods applied can be safely used in clinical practice in dogs and cats due to minimal post-operative complications and fast healing of laparoscopic incisions in comparison with classical surgical wounds, and that the harmonic scalpel is a safe surgical instrument.

Abstract:
OBJECTIVE: We sought to test whether the use of the harmonic scalpel would cause less pain and more rapid recovery in tonsillectomy patients versus the use of electrocautery. DESIGN AND SETTING: In a private practice community hospital, we conducted a prospective nonrandomized comparison of 156 pediatric tonsillectomy cases. Local anesthetic infiltrations and steroids were used at the discretion of the surgeon. Outcome variables consisted primarily of immediate-and mid-term pain, pain medications required, time to eating, morbidities and charges. RESULTS: There were no differences between the groups on an intention-to-treat basis except for costs, which were higher in the harmonic scalpel group. When rescue use of electrocautery was required to control bleeding in the in the harmonic scalpel patients, more pain and longer times to taking food were noted. CONCLUSIONS: Used with discretion the harmonic scalpel is equivalent to electrocautery for tonsillectomy. SIGNIFICANCE: The harmonic scalpel does not provide a major benefit over more conventional methods of tonsillectomy.

Abstract:
The objective of this study was to compare the effects of postoperative pain following ovariohysterectomy via harmonic scalpel assisted laparoscopy (HALO) and traditional ovariohysterectomy (OVH) in dogs. The study was designed as a randomized, blinded, prospective study. Sixteen, purpose-bred, intact female, Beagle dogs were used to complete the study. Dogs were placed into two groups. Group 1 included (8 dogs) that underwent ovariohysterectomy via HALO. Group 2 included (8 dogs) that underwent ovariohysterectomy via traditional OVH. Physiologic data, abdominal nociceptive threshold scores, and University of Melbourne pain scores (UMPS) were recorded at 2, 6, 12, 24, 48, and 72 hours following surgery. Blood samples for plasma cortisol, glucose, and creatine phosphokinase (CPK) were taken at the time of the incision and 2, 6, 12, 24, 48, and 72 hours following surgery. No significant surgical complications were encountered in either group. The HALO mean surgical time was significantly longer (55.7 minutes) than the traditional OVH (31.7 minutes). No significant differences were observed between the two groups for the pain measures of heart rate, respiratory rate, temperature, CPK, and glucose. The OVH group had significantly higher mean plasma cortisol levels at hour 2 following surgery than the HALO group (P=0.0001). The mean UMPS were significantly higher in the OVH group than the HALO group at all postoperative times (P=0.0001). Mean nociceptive threshold measurements revealed significantly higher tolerated palpation pressures in the HALO than the OVH group at all postoperative times, except hour 72 (P=0.0002). Dogs in this study appeared to be less painful with HALO procedures versus traditional OVH. The harmonic scalpel coagulated ovarian and uterine vessels completely with minimal collateral damage to surrounding tissues. The clinical relevance of this study demonstrates that harmonic scalpel-assisted laparoscopic ovariohysterectomy is a safe alternative to traditional OVH and offers a minimally invasive and less painful method of surgery.<br>Master of Science

Abstract:
Objective - To evaluate a surgical technique for performing laparoscopic bilateral ovariectomy in standing horses. Study Design - Experimental study. Animals or Sample population - 8 mares, age 2-20 years, weight 410-540 kg. Methods - Standing laparoscopic bilateral ovariectomy was performed in 8 mares with normal anatomy of the reproductive tract. The Harmonic Scalpel (an ultrasonically activated instrument) was used to transect the ovarian pedicle and to obtain hemostasis simultaneously. Necropsy was performed on 4 mares 3 days after surgery and 30 days following surgery on the remaining 4 mares. Gross and histopathologic evaluation of the ovarian pedicles was performed to characterize the effects of the Harmonic Scalpel on the transected tissue. Results - The Harmonic Scalpel achieved complete hemostasis of the vasculature of the ovarian pedicles in all mares. Median transection time for the ovarian pedicle was 28 minutes. Postoperative complications included transient fever in one mare, moderate subcutaneous emphysema in another, and incisional seroma formation in a third mare. Post-mortem examination 3 and 30 days postoperatively revealed no signs of generalized peritonitis, postoperative hemorrhage or adhesion formation. Mild to moderate acute inflammation, and scar formation with moderate chronic inflammation at the ovarian pedicle was found 3 and 30 days after surgery, respectively. Median depth of coagulation necrosis 3 days postoperatively was 2.87 mm. Conclusions - The Harmonic Scalpel appears to provide reliable hemostasis of the ovarian pedicle during elective laparoscopic ovariectomy in horses. Clinical Relevance - The Harmonic Scalpel represents a safe alternative to other means of hemostasis during elective laparoscopic ovariectomy in horses.<br>Master of Science

Abstract:
The objective of this research is to present a set of powerful simulation, design, and characterization tools suitable for studying novel nanophotonic devices. The simulation tools include a three-dimensional finite-difference time-domain code adapted for parallel computing that allows for a wide range of simulation conditions and material properties to be studied, as well as a semi-analytical Green's function-based complex mode technique for studying loss in photonic crystal waveguides. The design tools consist of multifunctional photonic crystal-based template that has been simulated with nonlinear effects and measured experimentally, and planar slab waveguide structure that provides highly efficient second harmonic generation is a chip-scale device suitable for photonic integrated circuit applications. The characterization tool is composed of a phase-sensitive measurement system using a lock-in amplifier and high-precision optical stages, suitable for probing the optical characteristics of nanoscale devices. The high signal-to-noise ratio and phase shift data provided by the lock-in amplifier allow for accurate transmission measurements as well as a phase spectrum that contains information about the propagation behavior of the device beyond what is provided by the amplitude spectrum alone.

Full text
Abstract:
Franz Liszt's Faust Symphony has suffered neglect since its premiere in 1857. The analysis in this study aims to clarify some of the misunderstandings which have led to this neglect, particularly concerning Liszt's formal structure and character portrayal. In the Faust movement, the flat 6th scale degree (♭6) plays a prominent role in harmonic organization. Nineteenth-century composers sometimes used the distinct sonic color of chromatic-third progressions, as Liszt does here between C and E rather than diatonic movement by fifth to evoke a distant dream-world state. Liszt's conspicuous and form-defining use of ♭6 in the Faust movement suggests fantasy and mysterious elements ripe for programmatic interpretation. In this dissertation, I will attempt to clarify how Liszt portrayed the character of Faust by using the flat 6th scale degree as a crucial harmonic organizing principle in the Faust movement.

Abstract:
Organologically classified as a melodic instrument, the electric bass has tonal and ergonomic characteristics that enhance its use beyond this designation. In this perspective, an increasing number of bassists seek to use the electric bass as a harmonic instrument. However, the lack of research on this approach hinders its development beyond individual initiatives. Based on an alternative tonal concept to consolidated practice, called LCCTO (Russell, 2001) and guided by a research design structured according to the concept of Affordances (Gibson, 1979) and the Perceptual Learning theory (Gibson &amp; Pick, 2000), this artistic research adopts experimentation as a learning method for performing vertical harmonies on the electric bass. The development of this path involves, (i) the construction of a harmonic vocabulary for the instrument and (ii) the creation of musical works from this vocabulary. The result of this work intends to contribute to the construction of a new paradigm for the performance of the instrument, for the academic discussion about it, and, consequently, bring pedagogical implications concerning the academic program for bassists and the teaching methodology for this harmonic content. Regarding the latter, the proposed research design, as well as the harmonic vocabulary, structured as a book, may point to an initial path for further debate. The results achieved so far point positively to the potential of using experimentation for the development of a, here called, Harmonic Approach to the Electric Bass. The experiments already concluded provided a considerable number of chords playable on the instrument, which has been organized as a dictionary, as well as extensive material resulting from articulations (simultaneous execution) between these chords and the different scales proposed in the LCCTO. Also included in this material resulting from the experiments, are the Creative Applications, organized as musical studies, which reflect, through composition, the use of the contents already obtained.

Abstract:
Higher Harmonic Control (HHC) is an approach for achieving reduced helicopter vibration by controlling the vibratory rotor airloads in such a way that the fuselage excitation is minimized. This paper is a historical look at how a program aimed at helicopter vibration reduction started as an outgrowth of fixed wing flutter suppression at NASA Langley Research Center, proved the HHC concept on aeroelastically scaled wind tunnel models, and went on to demonstrate viability in full scale flight testing on the OH-6A helicopter in 1982. Following the OH-6A flight tests the helicopter research community was stimulated to prove the effectiveness of HHC on different configurations through analysis, wind tunnel tests, and flight tests. All of these investigations have shown HHC to be effective in reducing vibration to levels not attainable with conventional vibration control methods and without any detrimental side effects. HHC development has progressed to the point that the technology is available for production application. The literature demonstrates that helicopter ride quality equivalent to that of fixed wing aircraft is available with application of HHC.

Abstract:
Rotor hub parasite drag remains one of the challenges in further improving the forward-flight capabilities of coaxial rotorcraft. Comprehensive datasets on notional coaxial hub configurations are rare, and more so at Reynolds numbers sufficiently high to preserve dominating flow structures downstream into the wake where they interact with the rotorcraft empennage and tail. The present investigation was designed specifically to improve the understanding of interactional aerodynamics effects and wake flow physics of counter-rotating coaxial rotor hubs. A unique dataset is presented on a rotor hub design equipped with the DBLN 526 airfoil at a diameter-based Reynolds number of 1.13x106, corresponding to approximately quarter-scale Reynolds conditions of a coaxial compound helicopter at 200 knots. The experiments measured the time-averaged and time-varying drag on the hub configuration, with focus on a cruise advance ratio of 0.25 and a high-speed condition at 0.60. In addition to measuring hub drag and its harmonic content, a unique aspect of the experiment was the use of multiple non-invasive flow-diagnostics techniques for the particular hub configuration, advance ratios, and Reynolds number. Specifically, stereoscopic particle-image velocimetry (SPIV) measured the three velocity components at two downstream locations in the hub wake, thus providing insight into and visualizing the development of the wake. In addition, a limited laser-doppler velocimetry (LDV) and a tomographic PIV (Tomo-PIV) data campaign were conducted that confirm the earlier SPIV measurements. A subset of all measurements is presented. Some new insight into the flow physics was gained, one example being the dependence of higher-harmonic per-rev flow structures in the wake on hub advance ratio.

Full text
Abstract:
Public procurement of goods and services contributes to about 15% of global greenhouse gas emissions. In the EU, public purchasing represents 15% of its GDP, acting as a major influencer on the market through the products and services acquired by governments from the local to national levels. The public sector has a role to play in leveraging this purchasing power to achieve the best societal value for money, particularly as we scramble to bend the curve of our planet’s warming. Globally, the construction and transport sectors each represent about 12% of government procurements’ GHG emissions. Furthermore, these sectors’ decarbonization efforts demand profound and disruptive technological shifts. Hence, prioritizing these sectors can make the greatest impact towards reducing the environmental footprint of the public sector and support faster decarbonization of key emitting industries. Meanwhile, the EU committed to achieving 55% reduction in GHG emissions by 2030 compared to 1990 levels. Drastic emissions reductions are needed at an unprecedented speed and scale to achieve this goal. Green Public Procurement (GPP) is the practice of purchasing goods and services using environmental requirements, with the aim of cutting carbon emissions and mitigating environmental harm throughout the life cycle of the product or service. While the EU and many of its Member States alike have recognized GPP as an important tool to meet climate goals, the formalization of GPP requirements at the EU level or among local and national governments has been fragmented. We call for harmonization to achieve the consistency, scale and focus required to make GPP practices a powerful decarbonization tool. We surveyed the landscape of GPP in the EU, with a focus on construction and road transport. Through interviews and policy research, we compiled case studies of eight Member States with different profiles: Sweden, the Netherlands, France, Germany, Estonia, Poland, Spain and Italy. We used this information to identify solutions and best practices, and to set forth recommendations on how the EU and its countries can harmonize and strengthen their GPP policies on the path toward cutting their contributions to climate change. What we found was a scattered approach to GPP across the board, with few binding requirements, little oversight and scant connective tissue from national to local practices or across different Member States, making it difficult to evaluate progress or compare practices. Interviewees, including policy makers, procurement experts and procurement officers from the featured Member States, highlighted the lack of time or resources to adopt progressive GPP practices, with no real incentive to pursue it. Furthermore, we found a need for more awareness and clear guidance on how to leverage GPP for impactful societal outcomes. Doing so requires better harmonized processes, data, and ways to track the impact and progress achieved. That is not to say it is entirely neglected. Most Member States studied highlight GPP in various national plans and have set targets accordingly. Countries, regions, and cities such as the Netherlands, Catalonia and Berlin serve as beacons of GPP with robust goals and higher ambition. They lead the way in showing how GPP can help mitigate climate change. For example, the Netherlands is one of the few countries that monitors the effects of GPP, and showed that public procurement for eight product groups in 2015 and 2016 led to at least 4.9 metric tons of avoided GHG emissions. Similarly, a monitoring report from 2017 showed that the State of Berlin managed to cut its GHG emissions by 47% through GPP in 15 product groups. Spain’s Catalonia region set a goal of 50% of procurements using GPP by 2025, an all-electric in public vehicle fleet and 100% renewable energy powering public buildings by 2030. Drawing from these findings, we developed recommendations on how to bolster GPP and scale it to its full potential. In governance, policies, monitoring, implementation and uptake, some common themes exist. The need for: • Better-coordinated policies • Common metrics for measuring progress and evaluating tenders • Increased resources such as time, funding and support mechanisms • Greater collaboration and knowledge exchange among procurers and businesses • Clearer incentives, binding requirements and enforcement mechanisms, covering operational and embedded emissions With a concerted and unified movement toward GPP, the EU and its Member States can send strong market signals to the companies that depend on them for business, accelerating the decarbonization process that our planet requires.

Progress Report (2014-2015) of the MDB Working Group on Sustainable Transport. Inter-American Development Bank, 2015. http://dx.doi.org/10.18235/0006461.

Full text
Abstract:
1. In the third year of the Multilateral Development Banks¿1 (MDBs) Joint Statement of 2012, our eight MDBs are on target to meet the goal of the Commitment to Sustainable Transport (hereafter the Rio+20 Commitment) to provide more than $175 billion of loans and grants for transport in developing countries over the coming decade (2012-2022). Collectively, in 2014, about $20 billion of new funding for transport projects was added to the $20 billion approved in the first year of our Commitment (2012) and $25 billion approved in 2013. 2. This $20 billion in funding comprised more than 193 approvals. 2 including: 103 for roads, 32 for urban transport , 14 for rail; 9 for airports. 6 for inland waterway and maritime projects, 29 for other transport projects. 3. In addition, more than 192 technical assistance (TA) projects were approved to support policy development, research and capacity building. 4. Increasingly, our MDBs are supporting more sustainable types of transport projects¿transport that is accessible, affordable, efficient, financially sustainable, environmentally friendly, and safe. Under a common reporting framework, our institutions have continued to make progress in assessing the sustainability of our transport lending in economic, social, and environmental terms. 5. In 2014, all MDBs completed an assessment of the sustainability of our entire annual transport lending, up from four MDBs in the year before. ADB used the Sustainability. Appraisal Rating Framework (STAR) while six MDBs used a modified version of STAR. WB used its own internal methodology. For MDBs that applied STAR or a modified STAR, a common four-point scale was used although the results are not yet fully comparable. Further efforts will be made to improve the comparability of ratings between the MDBs in the future. 6. The MDB Working Group on Sustainable Transport (WGST) identified quantitative indicators of project outputs and outcomes that can be used to complement the sustainability assessment. In this regard, relevant output and outcome indicators with readily available data are reported in the ¿In numbers¿ feature of each MDB, e.g. kilometer (km) of roads built or upgraded, km of railways built or upgraded, volume of transport mitigation investment, and percentage of road projects with road safety components. Discussions are ongoing to further harmonize reporting on indicators. 7. The year 2015 marks several important milestones in the international dialogue on development which are directly relevant to sustainable transport. These include completion of the 2030 Agenda for Sustainable Development and adoption of the new Sustainable Development Goals (SDGs), the 21st Conference of the Parties to the United Nations Framework Convention on Climate Change, and the Second Global Ministerial Conference on Road Safety to mark the mid-point of the United Nations Decade of Action for Road Safety. 8. The newly approved SDGs are expected to raise the attention given to addressing the different dimensions of sustainable transport, which will be conducive to the role of MDB-financed sustainable transport projects and programs. Our MDBs expect to take part in the process of deciding the indicators to be used for tracking progress on meeting the SDG targets and will make efforts to incorporate the indicators in our work.
