Strategic Planning for Integrated Mobility-on-Demand and Urban Public Bus Networks
Authors: Steiner Konrad , Irnich Stefan
Published: September 2020

App-based services and ridesharing in the field of mobility-on-demand (MoD) create a new mode of transport between motorized individual transport and public transportation whose long-term role in the urban mobility landscape and within public transport systems is not fully understood as of today. For the public transport industry, these new services offer new chances but also risks, making planning models and tools for integrated intermodal network planning indispensable. We develop a strategic network planning optimization model for bus lines that allows for intermodal trips with MoD as a first or last leg. Starting from an existing public transport network, we decide simultaneously on the use of existing line segments in the future fixed-route network, on areas of the city where an integrated MoD service should be offered, on how MoD interacts with the fixed-route network via transfer points, and on passenger routes fulfilling given service-level requirements. The main challenges from a modeling point of view are to capture the interplay between MoD services and the fixed public network, as well as the approximation of MoD costs taking into account that vehicle utilization is a key factor influencing these costs. We develop a path-based formulation and a branch-and-price algorithm, as well as an enhanced enumeration-based approach, to solve real-world instances to proven optimality. The solution methods are tested on instances generated with the help of real-world data from a medium-sized German city, Göttingen, that currently operates around 20 bus lines.
Practical use of non-steroidal anti-inflammatory drugs in farm practice
Authors: Reader Jon , Angel Tom , Rogers Imogen
Published: September 2020

The importance of pain relief in farm animals has never been further up the agenda for modern food production and farm animal practice. This has been driven by increased awareness amongst farmers, veterinary surgeons and consumers. This article looks at the practical use of non-steroidal anti-inflammatory drugs (NSAIDs) in farm animal practice for both adults and youngstock. The basic mode of action of NSAIDs is discussed and some of the evidence base that has been growing over the use of NSAIDs in cattle. It also highlights some of the present requirements of some of the retailers and auditing bodies.
CPD article: Understanding the social behaviour of dairy cattle can benefit welfare and productivity
Authors: George Adam J , Bolt Sarah L
Published: September 2020

Cattle are social animals, and an understanding of social associations and interactions is an important consideration when managing herds. Knowledge of this can facilitate positive welfare and productivity and it can also help to reduce the spread of disease. Social network analysis (SNA) is a tool that can be used to assess specific social interactions within cattle groups and help determine appropriate management actions in livestock enterprises. The aim of this review is to summarise how SNA can be used to study the social behaviour patterns of dairy cattle and highlight applications for this approach on dairy farms.
CPD article: Pre-breeding heifer examination and selection in UK beef herds
Authors: Miller Alice E J
Published: September 2020

The objective of this review is to evaluate examination tools and how they can be used to assess the breeding potential of beef heifers prior to service. Reproductive tract examination techniques, pelvic measurement, and antral follicle counts (AFC) are methods that are used and could be of value to farmers where they can either identify pubescent heifers and/or those with the best reproductive potential. Reproductive tract scoring (RTS) to assess the pubertal state and therefore reproductive status of replacement heifers is explored alongside further adaptions of this method. The use of pelvic measurement is considered: first, where a small pelvic area or an abnormal shaped pelvic inlet is identified, which may result in elimination from the breeding cohort to reduce the potential risk of dystocia and poor performance; and second, since it may be advocated for use in conjunction with other methods. AFC are included since they too may help identify the reproductive potential of heifers. Evaluation of these examination tools demonstrates that the use of modified RTS methods, to include ultrasound examination to detect the absence of a corpus luteum (CL), absence of a follicle ≥ 13 mm and the uterine horn diameter as well as pelvic measurements, could add value to heifer breeding soundness examinations (HBSE) when carried out.
Evidence-based veterinary medicine: searching the evidence in practice
Authors: Steele Mike
Published: September 2020

Evidence-based veterinary medicine techniques can be of enormous value to the general practitioner. There are some key processes to apply in order to search and find the science behind questions that arise relevant to cases, or to support standard operating procedures, and this article guides the novice through the basics. Entering text into internet databases can require keywords and phrases that can be built by asking a structured clinical question, including patient population, intervention, comparison and outcome. Useful databases available to the public are compared and basic appraisal of the resulting article hits is considered. A documented summary can be written and reviewed by peers before sharing the results with a wider professional community. If the outcomes can be linked to measurable results from the use of this summary, some tangible value can be evaluated from its creation.

CPD article: Equine gastrointestinal parasite infections
Authors: Wright Ian
Published: September 2020

Horses can be infected by a wide range of gastrointestinal parasites including roundworms, tapeworms and bot flies. Anthelmintics have formed the basis of intestinal worm control in horses through routine use for many years but the development of anthelmintic resistance now means that strategies are required to limit anthelmintic use while minimising parasitic disease. Pasture and stable hygiene, accurate dosing of horses and faecal testing are all key to reducing anthelmintic use, while not compromising welfare. A fundamental understanding of the parasites involved and communication with clients is vital if these aims are to be achieved.
Limb lengthening in the treatment of posteromedial bowing of the tibia
Authors: Gordon J. Eric , Schoenecker Perry L. , Lewis Thomas R. , Miller Mark L.
Published: September 2020

Purpose

Posteromedial bowing of the tibia is an uncommon but recognized congenital lower extremity deformity in children that can lead to limb length discrepancy (LLD) and residual angulatory deformity. The purpose of this study is to report a series of children at a single institution with posteromedial bowing treated by lengthening.

Methods

A retrospective review was carried out at our institution identifying 16 patients who were treated with limb lengthening for posteromedial bowing of the tibia and followed to skeletal maturity. Projected LLD was a mean of 7.7 cm (range 5.0 cm to 14.2 cm). Three patients were treated in a staged fashion with lengthening and deformity correction at age three to four years and subsequent definitive tibial lengthening. The remaining 13 patients were treated with limb lengthening approaching adolescence using circular external fixation.

Results

All patients were pain free and ambulated without a limp at final follow-up. The mean final LLD was 0.3 cm short. In spite of correction of distal tibial shaft valgus in 11 of the 16 patients, eight of the 16 (50%) required later correction of persistent, symptomatic ankle valgus by either hemiepiphyseodesis (seven patients) or osteotomy (one patient).

Conclusions

Children with posteromedial bowing of the tibial with projected LLD over 5cm can be effectively treated with lengthening. Patients with severe valgus of more than 30° of shaft valgus and difficulty ambulating at age three years can be successfully treated with a two-stage lengthening procedure. Attention should be paid in patients with posteromedial bowing to ankle valgus.

An Assessment of the Spatial Comfort at the Open Piazza of Baiturrahman Mosque, Banda Aceh, Indonesia
Authors: Sari Laina Hilma , Hasan Izziah , Meutia Erna
Published: September 2020

The Baiturrahman Grand Mosque is well-known as the identity of Banda Aceh town, Indonesia. The extensive renovation was carried out in 2015 to the Mosque, presenting an open piazza coated with glossy white marble replacing the previous greeneries and grass. This change creates a much different thermal sensation of the prior environment. This condition also invites the contrast to respond and define spatial comfort, including thermal and visual comfort. Therefore, this study conducts an assessment of thermal and visual comfort at the open piazza, which was done through field measurements. The outdoor thermal comfort was calculated using the equations proposed by Sangkertadi that are appropriate for the tropics. The visual comfort was examined using the De Boer glare scale. The result shows the discomfort appearance for both thermal and visual comfort. The study gives recommendations, such as planting greeneries, providing more shades for achieving lower outdoor air temperature. Replacing the glossy marble with the diffusing and rough surface will reduce the glare for getting the more acceptable visual comfort against the marbles.

Mormons in Paradise: The LDS centennial aloha shirt
Authors: Morgado Marcia A.
Published: September 2020

The centennial aloha shirt, an artefact in the collection of the Latter-Day Saints (LDS) Church History Museum in Salt Lake City, Utah, was manufactured by Paradise Sportswear in Honolulu and designed as a souvenir of a 1950s celebration of the 1850 landing of the first official LDS mission to the Sandwich Islands. The shirt is an archetypal example of garments manufactured in Hawai‘i as identity apparel. It is also an exemplary relic of the form, fabrication and cartoon-like printed designs characteristic of ‘golden age’ Hawaiian shirts – those manufactured between the mid-1930s and the mid-1950s. I situate Paradise Sportswear in the context of developments in the garment industry and in aloha shirt production at that time, review characteristics associated with golden age aloha shirts and examine details in the Museum’s garment that reference its significance as a historic costume artefact as well as its value as LDS memorabilia.

Ao fazê-lo, depois de rever a estratégia de alargamento da UE, a sua atratividade e o processo de adesão de novos membros, é dada especial atenção a alguns obstáculos que impedem a integração do Kosovo na UE, demonstrando que há ainda um longo caminho para os kosovares conseguirem cumprir os critérios de convergência impostos pelos 27.
Evolução do saneamento básico no sul do estado da Bahia, Brasil: análise comparativa estadual entre 2010 e 2018
Authors: Caldeira Juliane Ferreira , Aquino Davi Santiago
Published: September 2020

O adequado acesso ao saneamento básico é condição essencial para saúde pública, bem estar social e desenvolvimento econômico. Este trabalho objetivou analisar a evolução entre os anos de 2010 e 2018 de aspectos relativos a saneamento básico no estado da Bahia e na região sul desse estado. Enquanto as populações do estado e da região cresceram 5,6% e 3,0%, respectivamente, os crescimentos da extensão de redes de distribuição de água potável e de coleta de esgotos domésticos variaram entre 13,5% e 86,4%, respectivamente. Todavia, os índices sanitários da região se apresentaram inferiores aos estaduais, para ambos os aspectos. Por outro lado, o investimento per capita de verba federal em saneamento na região sul foi superior à média estadual de 2010 a 2016, com gradativa diminuição dessa proporção desde 2012. Embora tanto o estado quanto a sua região sul tenha apresentado melhorias nos índices de saneamento no período estudado, seus valores mais recentes ainda são inferiores às médias nacionais. Assim, é necessário que haja a continuidade e a intensificação dos investimentos, não apenas de origem federal, para a garantia da universalização do saneamento, da dignidade humana e da saúde pública.

Short Message Service (SMS) is a technology that provides service for sending and receiving messages between cell phones. Every individual, government, private or educational institution cannot be separated from using SMS as one of the information media. One of them is meeting notification information. But SMS technology can only carry limited data. SMS Gateway is a system that bridges mobile phones with the system that becomes a server with SMS as the information. In the SMS Gateway work system, the user's cellular phone sends an SMS containing the written format to access the information needed through the GSM network. The SMS will be received by the SMS Gateway cellular phone which will then be retrieved by the PC using the mfbus protocol via a data cable. Up to the PC, the text format will be processed by the SMS Gateway application program to produce information that will be sent to the SMS Gateway cellular phone using the mfbus protocol via a data cable. After that the information is sent by the SMS Gateway cellular phone to the user's cellular phone. With the SMS Gateway-based meeting notification application, it can provide detailed and concurrent notification of meeting information so that each meeting member can follow according to his schedule.

Background: The present study focuses on the problem of pregnancy maintaining in women with specific somatic conditions (an extragenital pathology). Aim: The paper aims to establish systemic clinical and psychological risk factors for the development of pregnancy termination in women with extragenital pathology, as well as determine the psychological markers of pregnancy termination and the psychological resources for maintaining a healthy pregnancy. Materials and methods: The data were obtained from the medical records of pregnant women, sociodemographic questionnaires and psychodiagnostic tests. The descriptive, comparative, correlational and discriminant methods were used for statistical analysis. 100 women participated in the study, 50 of them had the risk of pregnancy termination. Results: The risk factors of threatened miscarriage in women with extragenital pathology were identified: unconditional faith in God and transfer of the responsibility for pregnancy and childbirth; an unwanted pregnancy; negative attitude to all pregnancy-related restrictions; the dominant motive for pregnancy maintenance characterized by the wish to achieve a new social status; high self-worth; heightened self-esteem and lack of self-value and child significance; rigidity, tendency to behave and think stereotypically. The markers of pregnancy termination development were revealed: women’s desire to satisfy their needs for finding the meaning of life and for new social status achievement. The resources for healthy pregnancy were identified: the acceptance of pregnancy with all its physiological and social changes; value of the child and interest in his/her intrauterine manifestations; responsibility taking and vital activity. Higher activity indicators were associated with more favorable psychoemotional status (lower frustration and anxiety and higher positive emotions) and higher probability of pregnancy maintenance. Conclusion: The study contributes to the development of comprehensive programs of medical and psychological support for pregnant women with somatic pathologies as well as to the practice of pre-pregnancy counseling.
Instrumentalne wykorzystywanie władzy sędziowskiej po wyroku TSUE – wieloaspektowa analiza legalnej korupcji
Authors: Walczak Waldemar
Published: September 2020

The article presents considerations and multifaceted analyses of the conditions and motives of judicial decisions taken after the judgment of the TSUE 19 November 2019, in the context of how Poland’s judiciary system functions. It begins by explaining how to perceive and understand the essence of legal corruption in terms of the use of law, power and professional position. The possibilities of the intentional use of judicial power for specific needs and purposes is discussed in this context. The next part of the paper is devoted to a critical analysis of selectively interpreted right to a tribunal enshrined in art. 45 of the Polish Constitution in connection with other values enshrined therein. The right of every citizen to a fair and public hearing of their case, without undue delay by a competent, independent, impartial and independent court, is presented in terms of the constitutional perspective, the principle of equal treatment and non-discrimination. The problem outlined here is considered from the point of view of protection against the arbitrariness of authorities and the possibility of appealing against personnel decisions enabling employment to be taken up in selected positions in state institutions. Attention is paid to the privileged legal position of judges over other citizens. The issues described and the arguments presented in this article are entirely overlooked in the literature, as well as in public debate. What follows is an explanation of how TSUE rulings are interpreted differently by various public authorities. Reference is also made to the dictum of the Supreme Court judgment of 5 December 2019, which was issued in its Labour Law and Social Security Chamber. That process initiated specific actions and activities taken by individual groups of Supreme Court judges. Finally, the resolution of the combined three chambers of the Supreme Court on 23 January 2020, the judgment of the Constitutional Tribunal of 20 April 2020, and divergent decisions regarding the implementation of the TSUE’s position of 8 April 2020 are discussed.
Long non-coding RNA SNHG3 accelerates progression in glioma by modulating miR-384/HDGF axis

Published: September 2020

Glioma is a malignant primary brain tumor that occurs in the central nervous system and has threatened the well-being of millions of patients. It is well acknowledged that long non-coding RNA (lncRNA) SNHG3 participates in the regulation of proliferation, inflation, differentiation, and metastasis in many cancers. However, the regulatory effect of SNHG3 on glioma progression is still controversial. The expression of SNHG3 and HDGF was upregulated, whereas miR-384 was downregulated in glioma tissues, compared with the normal tissues. Interestingly, high SNHG3 contributed to low survival rate while low SNHG3 showed the opposite result. Moreover, SNHG3 or HDGF knockdown significantly suppressed proliferation, migration, and invasion and induced apoptosis in glioma. Meanwhile, restoration of HDGF abrogated the inhibition of SNHG3 silencing on glioma cell progression. Besides, miR-384 inhibitor attenuated SNHG3 silencing induced inhibition on HDGF mRNA and protein expression in A172 and SHG44 cells. LncRNA SNHG3 promotes cell proliferation, migration, and invasion in glioma by enhancing HDGF expression via miR-384 sponging, representing the promising targets for the development of novel therapeutic strategies.
