Kebutuhan pangan bagi manusia seperti sayuran semakin meningkat seiring perkembangan jumlah penduduk, sehingga perlu adanya produksi untuk mencukupi kebutuhan tersebut. Salah satu teknologi budidaya yang dapat dikembangkan yaitu produksi mentimun dengan memanfaatkan air salin limbah kerapu dan aplikasi amelioran silika secara hidroponik. Penelitian ini bertujuan untuk menentukkan pengaruh salinitas air limbah budidaya ikan kerapu dan pengaruh dosis silika terhadap pertumbuhan dan hasil mentimun yang dibudidayakan secara hidroponik. Penelitian ini dilakukan di Kebun Percobaan milik PT INDMIRA di Jalan Kaliurang km 19 pada bulan Maret - Juni 2018. Penelitian ini disusun dalam rancangan acak kelompok lengkap faktorial (3 x 3 + 1) dengan faktor pertama berupa konsentrasi air salin limbah budidaya ikan kerapu yang terdiri dari 3 aras yaitu 3 dS/m (U1), 6 dS/m (U2), dan 9 dS/m (U3), dan faktor kedua berupa dosis silika yang terdiri dari tiga aras yaitu 50 ppm (P1), 100 ppm (P2), dan 150 ppm (P3). Kontrol digunakan tanaman mentimun yang tidak diberi air salin limbah budidaya ikan kerapu dan silika. Hasil penelitian menunjukkan bahwa pemberian salinitas air limbah budidaya ikan kerapu pada kisaran konsentrasi 3 dS/m – 9 dS/m meningkatkan bobot kering akar. Aplikasi silika dengan dosis 50 ppm, 100 ppm dan 150 ppm meningkatkan bobot kering tajuk, kadar air nisbi. Dosis silika 100 ppm menunjukkan hasil klorofil yang paling tinggi dan meningkatkan rasio akar/tajuk. Aplikasi silika pada dosis 50 ppm dan 100 ppm pada salinitas 6 dS/m menunjukkan hasil ton/ha yang paling tinggi.

Published: March 2022

Kondisi iklim dan unsur hara sangat berpengaruh pada produksi cabai merah (Capsicum annuum L.). Ketersediaan unsur hara dipengaruhi oleh beberapa faktor salah satunya yaitu mikoriza. Mikoriza membantu tanaman dalam penyerapan air dan unsur hara. Penelitian ini bertujuan untuk mempelajari respons pertumbuhan tanaman cabai merah (Capsicum annuum L.) dan kadar kapsaisin buah cabai terhadap interval penyiraman dan pemberian mikoriza. Penelitian Ini menggunakan metode eksperimental dengan rancangan acak lengkap (RAL) yang terdiri atas dua faktor yaitu interval penyiraman dan pemberian mikoriza. Perlakuan interval penyiraman terdiri atas 2 kelompok yaitu penyiraman setiap hari dan tiga hari sekali. sedangkan perlakuan pemberian mikoriza terdiri atas 3 kelompok yaitu tanpa pemberian mikoriza, mikoriza 10 g/tanaman dan 15 g/tanaman. Parameter yang diamati yaitu tinggi tanaman, jumlah daun, kadar klorofil, jumlah buah, berat buah dan kadar kapsaisin buah cabai. Data yang diperoleh kemudian dianalisis menggunakan analisis variansi dan pengujian lanjut DMRT dengan α = 0,05. Hasil yang diperoleh yaitu kombinasi perlakuan mikoriza+interval penyiraman berpengaruh nyata terhadap jumlah daun, kadar klorofil, jumlah buah, berat buah dan kadar kapsaisin buah. Pemberian mikoriza meningkatkan kadar kapsaisin baik pada interval penyiraman setiap hari maupun tiga hari sekali. Interval penyiraman setiap hari menunjukkan berat buah lebih tinggi daripada interval penyiraman 3 hari sekali, namun kadar kapsaisin yang lebih rendah. Berdasarkan hasil penelitian yang telah dilakukan dapat disimpulkan bahwa perlakuan pemberian mikoriza 15g+interval penyiraman setiap hari menunjukkan hasil tertinggi pada jumlah daun, tinggi tanaman, jumlah buah, berat buah, serta kadar klorofil daun.

Tax Software versus Paid Preparers: Motivations and Predictors for the Mode of Tax Preparation Assistance
Authors: Rosenthal Leigh , Brown Bonnie , Higgs Julia L. , Rupert Timothy J. 
Published: March 2022

SYNOPSIS
In recent years, the number of taxpayers using tax preparation software has increased substantially; however, little is known about how these taxpayers differ from those using a paid professional. We gather data from a sample of taxpayers who used either tax software or a paid professional to examine their motivations for choosing their mode of tax preparation assistance. We find software users rated the importance of preparing the most accurate return significantly lower than the paid professional groups, while they rated the goal of minimizing the cost of preparation significantly higher in importance. We draw upon the Unified Theory of Acceptance and Use of Technology model to examine variables that predict the mode of tax preparation assistance. Results suggest measures representing performance expectancy, effort expectancy, and social influence are significant in distinguishing taxpayers using tax software from those using a paid preparer.

Bladder wall adhesion causing a vesicular septum in a dog following surgical cystotomy
Authors: Lew Lauren J. , Berent Allyson C. , Kirsch Meghan S. , Weisse Chick W. 
Published: March 2022

Abstract

CASE DESCRIPTION
An 8-year-old spayed female Yorkshire Terrier–Poodle dog was evaluated for persistent pollakiuria and stranguria following routine cystotomy for calcium oxalate cystoliths.

CLINICAL FINDINGS
The dog presented for a cystotomy with intermittent hematuria. Postoperative radiographs revealed no remaining cystoliths. Urine, cystolith, and bladder mucosal aerobic cultures were negative. Pollakiuria, stranguria, and hematuria developed immediately after surgery and persisted despite antibiotics. Ultrasound revealed suspected fibrous adhesions within the urinary bladder lumen connecting the dorsal and ventral bladder wall creating a septum. This was confirmed cystoscopically 4 weeks after surgery.

TREATMENT AND OUTCOME
Cystoscopic-guided laser ablation was performed to incise abnormal tissue connecting the ventral and dorsal bladder wall using a holmium:yttrium-aluminum-garnet laser. Three weeks later, ultrasound revealed adhesion resolution though mild pollakiuria and stranguria persisted. Oxybutynin was prescribed and clinical signs resolved. At 27 months after ablation, hematuria occurred with recurrent cystoliths. These cystoliths were removed by percutaneous cystolithotomy, documenting a cystoscopically normal bladder wall. The patient had normal urination for 55.5 months after ablation, with normal bladder wall thickness on ultrasound repeated at 27 and 36 months after ablation.

CLINICAL RELEVANCE
To the authors’ knowledge, an adhesion creating a septum between the dorsal and ventral bladder wall has not been previously reported as a complication after cystotomy in any species and should be considered as a cause of persistent lower urinary signs after surgery. Ultrasound identified the lesion in this dog. Because bladder abnormalities can develop quickly after surgery, ultrasound might be considered if urine testing is not supportive of infection. Cystoscopic-guided laser ablation was a successful minimally invasive treatment in this case.

Authors: Mardare Irina , Tiţa Irina , Zaharia Alexandru Constantin 
Published: March 2022

Abstract
This paper deals with hydraulic cylinders with and without end position cushioning. The reduction of the velocity at the end of the stroke is important in order to preserve the structural integrity and to avoid undesirable motion of the load. The mathematical model of such a hydraulic cylinder is shown, as well as the Matlab functional diagram for the system. It is also revealed the role of the working fluid, considering the actual recommendations regarding the biodegradable substances. It was considered both mineral base liquids and vegetable base liquids. The functional diagram offers the possibility to view for the hydraulic system the variation of the speed, flow rate, rate and stroke of the piston, in both cases: with and without end position cushioning. Is also shown a CFD analysis of fluid flow through the supply/outlet connections of the hydraulic cylinder.

Published: March 2022

Abstract
The overloading vehicle become an important problem for Europe Union, protecting the environment and increase the traffic safety. WIM or weigh-in-motion systems can monitor the traffic, determine the volume and type of traffic and detect the overload vehicles which are illegal. This paper discusses about applying the Failure Mode and Effect Analysis method for developing a new concept of WIM sensor, designed in PhD thesis from “Gheorghe Asachi” Technical University of Iaşi. FMEA method or also called potential failure modes and effects analysis is a step-by-step approach for determine and identifying all possible failures in a new design, or manufacture process. This new concept of sensor can be used for urban traffic in order to reduce the cars pollution in the cities by providing real-time data traffic, monitoring vehicles and detecting the overloaded trucks. The FMEA method was applied for identification of functional failure risks and preventing failures from an early stage of concept.

Published: March 2022

Abstract
Traffic studies are important because these provide significant information about traffic flows and traffic mobility in the area of study. Also, these studies can help to fluidize the traffic considering the actual number of cars and of the future cars which is estimated to increase due to considering traffic signals, roundabout or other traffic solutions. Traffic impact studies are important because the governmental agencies require them when a new building is developed as this can generate the increase of car traffic or can change the existing traffic paths. In this paper it will see how a new real estate construction area with mixed functions in the Miroslava village influence the traffic flow. This new building will lead to an increased the number of vehicles in the area and will change the existing traffic patterns, so it is required a traffic study.
Appropriate Mesh Size of Insect Screen for the Exclusion of the Cigarette Beetle, Lasioderma serricorne (F.)
Authors: Imai Toshihiro 
Published: March 2022

Summary
Insect screens are often used in tobacco facilities to exclude insect pests. Previous studies using laboratory cultures indicated that screens with openings smaller than 1.0 mm are adequate to prevent the passage of the cigarette beetle, Lasioderma serricorne. The beetles from natural populations are rather heterogeneous, and their body sizes may vary. Studies were conducted to confirm the relationship between mesh sizes and the body sizes of the cigarette beetles that can pass through the screens and to elucidate the size distribution of wild beetles. The results revealed that meshes can protect against beetles whose thorax width is larger than the openings in the mesh. Additionally, the widths of the prothoraxes of wild beetles captured in pheromone traps, which were generally considered to be male, ranged from 727–1070 μm (N = 169), and approximately 90% of the beetles had thoraxes that were narrower than 1000 μm. These data led to the conclusion that a 1.0 mm opening mesh is insufficient to protect against the cigarette beetle. Thus, Tyler standard #24 mesh (= US standard #25 mesh: 0.71 mm opening/sieve size) is recommended as an insect screen for tobacco facilities.
“It's a way of life”: Results from the Perceptions of Pain in Haemophilia study
Authors: Khair Kate , Kriukow Jarek , Holland Mike 
Published: March 2022

Abstract

Introduction
Pain is recognised as a subjective phenomenon, often defined as ‘whatever the experiencing person says it is, existing whenever the experiencing person says it does’. Pain is a critical aspect of life for many people with haemophilia (PWH) but is under-recognised and inconsistently managed by clinicians. As haemophilia management moves towards non-factor-based treatments which may normalise life experience, it is unclear how this will impact on the experience and management of pain.

Aims
The Perceptions of Pain in Haemophilia study aimed to identify the impact of pain on men with haemophilia in the UK.

Methods
The study used mixed qualitative research methods (paper-based questionnaires and focus group interviews). Eligible PWH aged >18 years were invited to participate in a focus group to discuss pain, assessment and management. Each focus group discussion was recorded, transcribed and analysed thematically.

Results
Eighteen participants (13 haemophilia A (12 severe) and 5 severe haemophilia B) age range 18–58 years (median 32.5 years) joined focus groups conducted using an online video platform. The majority (95%) were treated with prophylaxis and reported few recent bleeds. Three main themes emerged: the impact of pain, managing pain, and factors influencing the experience of pain. Participants connected their earliest experiences of pain with childhood; it impacted their mental health and wellbeing, daily habits, routines, sports, hobbies, social life, work and education. Participants recognised the difference between the pain of acute bleeds and arthritic pain. Many did not like taking strong analgesics due to side-effects and concerns around addiction. Participants doubted the value of pain scales and noted a lack of empathy and understanding among health care professionals (HCPs), but valued physiotherapists. Participants recognised the value of talking about the negative impact of their pain experiences; however, they reported that family members, who often provided the most support, could not always truly understand their pain.

Conclusion
Pain is ‘normal’ for PWH, who adopt it into part of their everyday life experience. HCPs are ideally placed to impact this experience but seem to lack insight as to the extent of pain and how to manage it beyond prescribing stronger analgesia. The social and psychological implications of chronic pain should be better addressed by HCPs. This includes being cognisant that new therapeutic options will not resolve old pain.

Published: March 2022

The purpose of this study is to understand the effect of dividend policy on a company's financial performance. This article examines the research gap and then builds a research model using ROA as the dependent variable, dividend rate and dividend payment decision as independent variables, and firm size, leverage, and income growth as control variables. This paper collects data and financial reports from 196 companies from the manufacturing sector listed on the Indonesia Stock Exchange from 2016 to 2020. The results of the analysis show that dividend payment decisions have no effect on manufacturing companies as measured by the financial performance of accounting-based companies but this raises expectations. the market for the company. In addition, this paper finds that manufacturing companies offer low dividend rates which have a positive impact on the company's financial performance but have a negative effect on market expectations. This paper offers some informative results-based recommendations, including better dividend policy models, lower dividend yields, and clearer dividend payment decisions.
