Authors: Carrillo Veronica , Petrie John , Timbe Luis , Pacheco Esteban , Astudillo Washington , Padilla Carlos , Cisneros Felipe
Published: March 2021

The current study presents an experimental procedure used to determine bedload sediment transport rates in channels with high gradients and coarse sediment. With the aim to validate the procedure for further investigations, laboratory experiments were performed to calculate bedload transport rates. The experiments were performed in a laboratory tilting flume with slopes ranging from 3% to 5%. The sediment particles were uniform in shape (spheres). The experiments were divided into four cases based on sediment size. Three cases of uniform sizes of 10 mm, 15 mm and 25 mm and a case with a grain size distribution formed with the uniform particle sizes were considered. From the experimental results a mathematical bedload transport model was obtained through multiple linear regression. The experimental model was compared with equations presented in the literature obtained for gravel bed rivers. The experimental results agree with some of the models presented in the literature. The closest agreement was seen with models developed for steep slopes especially for the highest slopes considered in the present study. Therefore, it can be concluded that the methodology used can be replicated for the study of bedload transport rates of channels with high gradients and coarse sediment particles to study more general cases of this process such as sediments with non-uniform shapes and sizes. However, a simplified model is proposed to estimate bedload transport rates for slopes up to 5%.
Changes of Flow and Sediment Transport in the Lower Min River in Southeastern China under the Impacts of Climate Variability and Human Activities
Authors: Wang Wen , Wang Tianyue , Cui Wei , Yao Ying , Ma Fuming , Chen Benyue , Wu Jing
Published: March 2021

The Min River is the largest river in Fujian Province in southeastern China. The construction of a series of dams along the upper reaches of the Min River, especially the Shuikou Dam, which started filling in 1993, modified the flow processes at the lower Min River, leading to the significant increase in low-flows and slightly decrease in flood-flows. At the same time, reservoirs have more effects on the sediment transport process than flow process by trapping most sediment in the reservoirs, and greatly reduced the amount of sediment transporting downstream. Increase in vegetation cover also contributes to the decrease in sediment yield. The reduction in sediment together with excessive sand mining in the lower Min River resulted in the severe downward erosion of the riverbed. Using a reformulated elasticity approach to quantifying climatic and anthropogenic contributions to sediment changes, the relative contribution of precipitation variability and human activities to sediment reduction in the lower Min River are quantified, which shows that the sediment reduction is fully caused by human activities (including land use/land cover changes and dam construction).

Authors: Ghaderi Amir , Dasineh Mehdi , Aristodemo Francesco , Aricò Costanza
Published: March 2021

The submerged hydraulic jump is a sudden change from the supercritical to subcritical flow, specified by strong turbulence, air entrainment and energy loss. Despite recent studies, hydraulic jump characteristics in smooth and rough beds, the turbulence, the mean velocity and the flow patterns in the cavity region of a submerged hydraulic jump in the rough beds, especially in the case of triangular macroroughnesses, are not completely understood. The objective of this paper was to numerically investigate via the FLOW-3D model the effects of triangular macroroughnesses on the characteristics of submerged jump, including the longitudinal profile of streamlines, flow patterns in the cavity region, horizontal velocity profiles, streamwise velocity distribution, thickness of the inner layer, bed shear stress coefficient, Turbulent Kinetic Energy (TKE) and energy loss, in different macroroughness arrangements and various inlet Froude numbers (1.7 < Fr1 < 9.3). To verify the accuracy and reliability of the present numerical simulations, literature experimental data were considered.

Authors: Al-Heeti Mohamed M. , Fadhel Mohammed A.
Published: March 2021

In the paper, we present an analytical comparison for various modulation techniques that can be used in a digital communication system. Digital modulation offers more powerful security, information, quality communication, and great capacity. Therefore, digital modulation systems have a maximal and important role in their capacity to transfer bigger amounts of data than analogue ones. There are more types of digital modulation like multiple amplitudes, frequencies, and phase shift keys. The results examine the comparisons of modulation techniques and the benefits of each system to determine which would be the most suitable for a specific application. The paper also discusses the effectiveness of different bandwidth and power efficiency factors.

Published: March 2021

Advances in technology are increasing the demand for the biometric technology of palm print detection. This work presents a region of interest segmentation algorithm for palm prints based on Hue Saturation Brightness. The aim of this work was to detect palm print region of interest based on skin color and geometric features. After a color palm image is read as a JPEG file, the algorithm passes through three main stages of preprocessing: palm localization, region of interest localization and region of interest extraction. The preprocessing stage consists of three steps: conversion to Hue Saturation Brightness, skin color modeling, and de-noising. The second main stage of palm localization consists of clipping from the left, from the right, from the top and from bottom. The third stage consists of the two steps of determining and extracting region of interest. The algorithm was tested on a dataset of 180 palm images from the Institute of Automation Chinese Academy of Sciences dataset, which contains an equal number of right-hand and left-hand palm images. The results showed that the Hue Saturation Brightness color space for skin detection was superior to other recognition methods, with an accuracy rate of 98.8%.

CT-Guided Transforaminal Epidural Injections
with Local Anesthetic, Steroid, and Tramadol
for the Treatment of Persistent Lumbar
Radicular Pain
Authors: Wewalka Mathias
Published: March 2021

Background: A substantial number of patients with persistent lumbar radicular pain are treated
with a multimodal spectrum of conservative therapies without lasting effect. The duration of
pain is certainly a risk factor for chronification. There is evidence that guided periradicular
infiltrations are a valid option in the treatment of radiculopathies. Usually a combination of local
anesthetic and/or corticosteroid is injected. Tramadol is being used for perioperative analgesia
and has been shown to provide effective, long-lasting pain relief after epidural administration.
Objective: The aim of this pilot study was to evaluate the efficacy of serial CT-guided
transforaminal nerve root infiltrations with a supplement of tramadol for patients with persistent,
radicular pain.
Study Design: Interventional cohort study.
Setting: Outpatient department for interdisciplinary pain medicine.
Methods: 37 patients who had radicular leg pain for over 9 weeks received up to 3 CTguided transforaminal nerve root infiltrations at intervals of 2 weeks as long as their level of
pain was over 3 on a numerical rating scale from 0 to 10. 50 mg of Tramadol were added to
a combination of local anesthetic (Ropivacain, 2 mg) and corticosteroid (Triamcinolon, 40 mg).
Evaluations were carried out 24 hours after the Infiltration as well as 2 weeks, 3 and 6 months
after the treatment series. The intensity of their radicular pain was measured by a numerical
rating scale (NRS). Pain reduction of at least 50% was defined as successful outcome.
Results: In total, 65 infiltrations were carried out with pain relief in more than 90% of the
patients within 24 hours and an average pain reduction of 64%. Six months post-injection 23 of
34 patients available for follow-up (67.6%) had a successful pain reduction of 84% on average.
No adverse effects ascribable to the use of tramadol were noted.
Limitations: Due to the lack of a control group we cannot make any statement if tramadol
improves short-term pain reduction.
Conclusion: Fast and lasting pain relief is the key to optimize rehabilitation for patients with
radicular pain. There is a physiological rationale that the opioid receptors at the spinal level could
be used to optimize the analgetic effect of guided periradicular injections. In our case series,
serial CT-guided selective nerve root infiltrations with the supplement of tramadol were found
to be highly effective in the treatment of persistant radiculopathies. Randomized controlled trials
will be necessary to clarify the possible benefit of the supplement of an opioid.
Key words: Serial, nerve root infiltration, tramadol, chronic pain, outcome.
Changes in Bone Mineral Density in
Postmenopausal Women Treated with Epidural
Steroid Injections for Lower Back Pain
Authors: Hwang Byeong-mun
Published: March 2021

Background: Therapy with corticosteroids often results in bone loss and
corticosteroid-induced osteoporosis. In previous studies, bone mineral density (BMD)
has been examined after administration of relatively high oral doses of corticosteroids.
However, practitioners use comparatively lower doses of corticosteroids for epidural
steroid injections (ESI). The interactions and relationships between BMD and ESI remain
to be determined.
Objective: The aim of this study was to explore the relationship between BMD and
ESI in postmenopausal women treated for lower back pain.
Study design: This study was a retrospective evaluation.
Methods: We reviewed the medical records of postmenopausal women with lower
back pain who were treated with or without ESI. BMD was measured before treatment
and one year after treatment in the lumbar spine, femoral neck, and total femur. A
total of 90 postmenopausal women were divided into 2 groups. Group 1 patients
received medications without ESI; Group 2 patients received ESI more than 4 times,
with a cumulative administered triamcinolone dose of > 120 mg.
Results: Decreased BMD was observed in patients treated with ESI. However, no
significant difference was observed between or within the groups in terms of mean
percentage change from baseline BMD.
Limitations: First, this study is limited by the fact that it was retrospective. Second,
our study did not consider the use of ESI with high-dose corticosteroids. Third, our
study did not include any long-term assessments of the effects of ESI on BMD.
Conclusions: These data suggest that ESI using triamcinolone (over 200 mg) for
a period of one year will have a negative effect on BMD in postmenopausal women
treated for lower back pain. However, ESI therapy using a maximum cumulative
triamcinolone dose of 200 mg in one year would be a safe treatment method with no
significant impact on BMD.

Skin Biopsy in Complex Regional Pain
Syndrome: Case Series and Literature Review
Authors: Schwartzman Robert J.
Published: March 2021

Background: Accumulating experimental and clinical evidence supports the hypothesis
that complex regional pain syndrome type I (CRPS-I) may be a small fiber neuropathy.
Objectives: To evaluate the use of commercially available standard biopsy methods to
detect intradermal axon pathology in CRPS-I, and to ascertain if these structural changes
can explain quantitative sensory testing (QST) findings in CRPS-I.
Study Design: Retrospective review of charts and laboratory data.
Setting: Outpatient clinic
Methods: Skin biopsies from 43 patients with CRPS-I were stained with PGP 9.5,
and epidermal nerve fiber density, sweat gland nerve fiber density and morphological
abnormalities were evaluated. Thirty-five patients had quantitative sensory testing.
Results: Alterations in skin innervation were seen in approximately 20% of CRPS-I
patients with commercial processing. There were no patient characteristics, including
duration of disease, that predicted a decreased epidermal nerve fiber density (ENFD). There
was no consistent relationship between QST changes and ENFD measured by standard
commercial skin biopsy evaluation procedures.
Limitations: Commercial processing of tissue does not utilize stereologic quantitative
analysis of nerve fiber density. Biopsy material is utilized from a proximal and distal source
only, and differences in denervation of a partial nerve territory may be missed. The
functional attributes of small fibers cannot be assessed.
Conclusions: The negative results indicate that CRPS-I may be associated with changes
in the ultramicroscopic small fiber structure that cannot be visualized with commercially
available techniques. Alternatively, functional rather than structural alterations of small
fibers or pathological changes at a more proximal site such as the spinal cord or brain may
be responsible for the syndrome.

Fluoroscopic Epidural Injections in Cervical
Spinal Stenosis: Preliminary Results of a
Randomized, Double-Blind, Active Control Trial
Authors: Manchikanti Laxmaiah
Published: March 2021

Background: Cervical spinal stenosis is a common disease that results in considerable morbidity
and disability. There are multiple modalities of treatments, including surgical interventions and
multiple interventional techniques including epidural injections. The literature on the effectiveness
of cervical epidural steroids is sporadic. Emerging evidence for cervical interlaminar epidurals for
various conditions in the cervical spine is positive; however, the effect of fluoroscopic epidural
injections in cervical spinal stenosis has not been studied.
Study Design: A randomized, double-blind, active control trial.
Setting: A private interventional pain management practice, a specialty referral center in the
United States.
Objectives: To evaluate the effectiveness of cervical interlaminar epidural injections with local
anesthetic with or without steroids in the management of chronic neck pain with upper extremity
pain in patients with cervical central spinal stenosis.
Methods: Patients with cervical central spinal stenosis were randomly assigned to one of 2 groups:
injection of local anesthetic only or local anesthetic mixed with non-particulate betamethasone.
Sixty patients were included in this analysis. Randomization was performed by computer-generated
random allocation sequence by simple randomization.
Outcomes Assessment: Multiple outcome measures were utilized including the Numeric
Rating Scale (NRS), the Neck Disability Index (NDI), employment status, and opioid intake with
assessment at 3, 6, and 12 months post-treatment. Significant pain relief or functional status was
defined as a 50% or more reduction of NRS or NDI scores.
Results: Significant pain relief was seen in 73% in Group I and 70% in Group II, in Group II
showing both significant pain relief and functional status improvements. Group I’s average relief
per procedures was 11.3 ± 5.8 weeks; for Group II it was 8.6 ± 3.6 weeks, whereas after initial 2
procedures, average relief was 13.7 ± 8.7 weeks in Group I, and 13.6 ± 4.7 weeks in Group II. In
the successful group, the average total relief in a one-year period was 42.2 ± 14.7 weeks in Group
I and 34.3 ± 13.4 weeks in Group II, with 76% in Group I and 77% in Group II.
Limitations: Study limitations include the lack of a placebo group and that this is a preliminary
report of only 60 patients, 30 in each group.
Conclusion: Patients who have chronic function-limiting pain that is secondary to cervical central
stenosis might receive relief with cervical interlaminar epidurals of local anesthetic, whether with
or without steroids.

Experimental Evaluation of the Risk of
Extradiscal Thermal Damage in Intradiscal
Electrothermal Therapy (IDET)
Authors: Wegener Bernd
Published: March 2021

Background: In 2000 the intradiscal electrothermal therapy (IDET) procedure for the
treatment of discogenic pain was introduced. The technique involves the positioning of
an intradiscal catheter with a temperature-controlled thermal resistive heating coil at
the inner posterior annulus. The therapeutic mechanism of IDET combines the thermocoagulation of native nociceptors and in-grown nonmyelinated nerve fibers with collagen
shrinkage, stabilizing annular fissures. Thermal nerve root injuries were described with
IDET. The temperature in relation to the distance from the catheter tip was investigated.
The intradiscal temperature distribution during treatment with IDET was also described.
Objective: To examine the temperature distribution outside the disc near neural
structures and the risk of thermal damage to nerve tissue during a correctly performed
IDET procedure.
Study Design: Experimental study.
Setting: Biomechanical laboratory of an academic orthopedic surgery department.
Methods: Testing was performed on cadaveric human lumbar spines with 10 intact
intervertebral discs in a circulating water bath. Five thermocouples were attached to
different locations on the disc. The temperature was recorded for 26 minutes. In addition,
surface temperatures were recorded using an infrared camera. For the application of
IDET, we used the Electrothermal 20S Spine System by Smith & Nephew and the standard
clinical protocol.
Results: The shape of the recorded temperature curves was quite heterogeneous. Inside
the spinal canal, temperatures as high as 45.2°C were recorded for a very short time.
Temperature monitoring with the infrared camera demonstrated a change in temperature
clearly restricted to the nucleus of the disc.
Limitations: The temperature distribution depends on the exact position of the IDET
probe, which will never be 100% identical between individual experiments.
Conclusion: This study shows that temperatures generated within the spinal canal
during IDET do not appear to be high enough to cause nerve damage.

Published: March 2021

Artificial intelligence is a technology developed to make machines think like humans. Aristotle's historical artificial intelligence entered the health sector in the 1970s. The first application for artificial intelligence in the internist-1 field in health care, the Casnet expert system, and MYCIN. This technology was later introduced to many areas of health care. The main purpose of this application is for the benefit of doctors and patients. In general, applications, medical decisions, early diagnosis and treatment, drug development, and medical imaging issues deserve attention. Another important issue is the concern about the benefits of artificial intelligence, as well as the possibility of replacing the physicians in charge when medical decisions are left entirely to artificial intelligence. This study aims to provide readers with general information about the areas where artificial intelligence is used in health care. In this study, 14 applications were examined and outstanding results were observed. When doctors say that a comatose patient cannot wake up, artificial intelligence says that a comatose patient can wake up and the patient can wake up. Other advanced artificial intelligence has shown that it can detect cancer more accurately than 58 skin specialists. One study concluded that artificial intelligence with a predictive treatment approach lowered health care costs by 5 to 9% and could lead to an increase in life expectancy of 0.2 to 1.3 years.

ABSTRACTThe dance work entitled "Nan Lah Lapuak" was created by Erwin Mardiansyah based on empirical experiences that occurred around workers. Based on that experience, the authors gained understanding and interpretation of Minangkabau traditional life that began to fade, especially in Nagari Regency, Paninggahan Regency, Solok District. Adaik is an understanding held by a person or community for a long time and has undergone inherited inheritance. However, in the community residing in Nagari Paninggahan, Junjung Sirih Sub-district, Solok District was formerly adhered to and became a guide in living life, but now the habit has begun to fade. One of the causes of customary fading is due to the development of the era and the era of globalization that flourished in society. To bring ideas into works of art, artists use heroic themes and dramatic types. In addition to the movements of the dancers in this work wearing traditional costumes and traditional costumes that have been modified as one of the symbols that have been faded by the times and technology. Exploration of motion in this work rests on the Minangkabau silk movement and is combined with modern techniques, and adapted to the character possessed by the worker.

Authors: Rahmadiani Devi
Published: March 2021

Pemakaian telepon seluler semakin bertambah tiap tahunnya. Tercatat bahwa jumlah telepon seluler yang beredar di Indonesia melebihi dari jumlah penduduk Indonesia pada tahun 2013. Telepon seluler menggunakan gelombang elektromagnetik sebagai media penyalur data. Gelombang elektromagnetik termasuk gelombang tipe non-ionizing, dimana gelombang elektromagnetik tidak memiliki energi yang cukup kuat untuk memutus ikatan kimia pada sistem tubuh, Namun, penggunaan telepon seluler yang memancarkan gelombang elektromagnetik dalam intensitas yang tinggi dan jarak yang dekat dengan tubuh teteap dapat menimbulkan efek negatif pada tubuh. Gelombang elektromagnetik dapat meningkatkan jumlah radikal bebas. Peningkatan radikal bebas yang berlebihan dapat menyebakan stres oksidatif. Stres oksidatif dapat memicu peroksidasi lipid, yang dapat merusak membran sperma dan menurunkan kualitas sperma. Tujuan dari penulisan artikel ini adalah untuk mengetahui dampak dari gelombang elektromagnetik yang dipancarkan telepon seluler terhadap kualitas sperma.

Published: March 2021

The basic requirement by adding confusion is to ensure the confidentiality of the secret information. In the present article, we have suggested new methodology for the construction of nonlinear confusion component. This confusion component is used for enciphering the secret information and hiding it in a cover medium by proposed scheme. The proposed scheme is based on ring structure instead of Galois field mechanism. To provide multi-layer security, secret information is first encrypted by using confusion component and then utilized three different substitution boxes (S-boxes) to hide into the cover medium

This study aims to analyze the effect of profitability ratios, solvency ratios, and liquidity ratios towards firm value of the public companies listed on the Indonesia Stock Exchange in the period 2015-2017. The population is twelve automotive and component subsector companies. Sampling of this study was conducted using purposive sampling technique. Data is in the form of secondary data from each company’s financial statements from the Indonesian Stock Exchange website. The analytical method used is multiple linear regression analysis. The results show that of the ratios that measure the company’s financial performance, only the profitability ratio has a significant positive effect on firm value. The solvency ratio and the liquidity ratio does not significantly influence the firm value. But simultaneously, the three financial ratios show a significant positive effect towards firm value. This research model is quite strong, because all three variables contribute highly in explaining variations in firm value.

Various issues in villages become one of the obligations of academicians or lecturers to solve the problems faced by society. Golong is a village that has the uniqueness and opportunity to be a developed village both for natural resources and human resources. Even though the society has low income but the spirit of the society is high. Therefore, community service team initiates to guide in learning English for children and women teenagers in Golong, Narmada, and West Lombok. Collaborative learning is one of the methods used in this community service activity because it involves and provides plenty opportunity to the learners for sharing and discussing of the materials and to solve the matters. Consequently, by applying the collaborative learning approach, the learners are expected to be more active in learning and cooperating so that their habits of learning and collaboration to be implemented by the learners in workplaces. The community service results show that guidance and empowerment in learning English have a positive impact and have a good response from the learners and community. The empowerment has a pivotal role in encouraging the learners’ motivation and improves the learners’ achievements. The community service activity is expected to be able to be sustainable and become one of cooperation between institutions and villages so that the institution contributes to shape the society to be smart, wise, and prosperous.
Canto y ciencia
Authors: García-López Isabel
Published: March 2021

El estudio de la voz cantada puede abordarse tanto desde el punto de vista artístico como desde el científico. Estas dos perspectivas no siempre se combinan en los profesionales del canto ni en los de la medicina.

El acto de cantar comienza a nivel cerebral con la intención voluntaria de hacerlo y se produce gracias a la fuente de energía, el aire, que hace vibrar las cuerdas vocales situadas en la laringe para producir el sonido. Dicho sonido se modifica en el tracto vocal permitiendo la articulación del lenguaje y los fenómenos de resonancia de la voz. Todo este proceso está gobernado por la audición, elemento fundamental del canto.

El objetivo de este artículo es revisar los elementos anatómicos que intervienen en todo este proceso, así como explicar los fenómenos fisiológicos que hacen que se produzca la voz cantada.
Immer vor dem richtigen Regalfach
Authors: Abraham Sven
Published: March 2021

Paletten- oder Behälterregale bestehen im Wesentlichen aus vertikalen Stehern und horizontalen Riegeln. In den letzten 20 Jahren haben sich diese Einrichtungen in ihrer Bauart erheblich verändert. Die Regale werden durch thermische und dynamische Einflüsse belastet und die Stoßlasten beispielsweise durch die Integration von Shuttle-Systemen erhöht. Die daraus resultierenden Verformungen von Regalbauteilen unter Last, zum Beispiel durch Durchbiegung oder Dehnung, müssen deshalb genauestens betrachtet werden.
Experimentelle Untersuchung zu faser- verbundgerechten Crash-Wirkmechanismen bei axialer Druckbelastung/Experimental Studies on Fiber Com- posit-appropriate Crash Mechanisms under Axial Pressure Load
Authors: Nossol Patryk , Saleem Arham
Published: March 2021

INHALT Der Leichtbau und die Crash-Sicherheit im Passagiertransport, wie etwa bei Schienen- und Fahrzeugbau nehmen stetig an Bedeutung zu. Besonders bei neuartigen Antrieben mit Elektromotor zeigen sich neue Sicherheitsanforderungen beispielsweise für den Batterieschutz. Daher sind Untersuchungen zur Entwicklung von leichten Crash-Energie-Absorbern von großer Relevanz. Im Rahmen der vorliegenden Arbeit wurden deshalb sechs verschiedene Crash-Wirkprinzipien experimentell untersucht und ausgewertet. Bei fünf davon erfolgte die Konzeption in Faserverbundbauweise sowie die Variation bezüglich verschiedener Laminataufbauten. Als Referenz-Wirkprinzip diente das duktile Versagen eines Leichtmetalls (Aluminium). Die Prüfung fand mittels Hochgeschwindigkeitsdruckversuchen an Crash-Rohren statt. Nach Auswertung und Gegenüberstellung der Ergebnisse anhand des Kriteriums der spezifischen Energieabsorption (SEA) zeigten sich deutliche Vorteile bei Crash-Rohren mit einem Inversions-Mechanismus.

Хозяйственно-биологическая оценка перспективных образцов двукисточника тростникового в условиях Севера
Authors: Косолапова Т. В.
Published: March 2021

В селекционном питомнике по биологическим и хозяйственным признакам в сравнении с районированным сортом Первенец (стандарт) изучали следующие перспективные популяции двукисточника тростникового: Канадская (СН-62), Карельская (СН-186) и три местные формы из Республики Коми (СН-31, СН-73, СН-115). Почва опытного участка дерново-подзолистая. В вегетационный период метеорологические условия в годы изучения были различными и отражали неустойчивый характер выпадения и распределения осадков. В результате исследований установлено, в прохождении фенологических фаз на 3-4 дня от стандарта отставали Канадская (СН-62) и Карельская (СН-186) популяции. Продолжительность периодов от начала весеннего отрастания до цветения составила 51-65 дней, до созревания – 68-87 дней. По высоте растений стандарт превышал СН-73. Облиственностью более 39% выделился СН-186. По урожайности зеленой массы образцы между собой различались незначительно, наиболее высокой она была у СН-73. По урожайности семян СН-73 и СН-115 превысили стандарт соответственно на 20 и 44%. По содержанию сырого протеина все селекционные номера превосходили стандартный сорт Первенец. Ряд изученных номеров по комплексу хозяйственно-ценных признаков будет использоваться в дальнейшей селекционной работе.

Authors: Liguori Francesca , Moreno-Marrodán Carmen , Barbaro Pierluigi
Published: March 2021

Metal-catalysed depolymerisation of plastics to reusable building blocks, including monomers, oligomers or added-value chemicals, is an attractive tool for the recycling and valorisation of these materials. The present manuscript shortly reviews the most significant contributions that appeared in the field within the period January 2010–January 2020 describing selective depolymerisation methods of plastics. Achievements are broken down according to the plastic material, namely polyolefins, polyesters, polycarbonates and polyamides. The focus is on recent advancements targeting sustainable and environmentally friendly processes. Biocatalytic or unselective processes, acid–base treatments as well as the production of fuels are not discussed, nor are the methods for the further upgrade of the depolymerisation products.
Put Your Money Where Your Mouth Is: The Influence of Designated Funding upon Strategic Implementation in US Municipalities
Authors: Mitchell David , Kanaan David , Stoeckel Sarah
Published: March 2021

Prior to implementation of strategic initiatives, US municipalities must decide to either designate implementation funding or ask the implementing agency to do so within its existing resources. Although limited empirical evidence indicates that designating implementation funds universally improves implementation outcomes, strategic management scholars and practitioners have increasingly endorsed contingent approaches adapted to varying environmental, organizational, and project characteristics. This conflict within theory and practice requires further examination to discern whether designated implementation funding can be considered a universal best practice or effective only in particular contexts. By surveying municipal leaders from 43 U.S. municipalities about the adequacy of implementation funding regarding 207 of their strategic initiatives, this study finds that designating implementation funds is crucial to the success of all strategic initiatives and therefore should not be applied in a contingent manner; posing a formidable challenge to contingent theories of strategic implementation and existing practices of municipal strategic management.
