The zinc (Zn) doped bismuth ferrite (BiFeO3) have been successfully synthesized through the sol-gel autocombustion method as a microwave absorbent material through a composite process with silicone rubber. The characterizations of zinc doped bismuth ferrite nanoparticles was done using the X-ray diffraction (XRD), the Fourier transform infrared (FTIR), the vibration sample magnetometer (VSM), and the vector network analyzer (VNA). Through the XRD test, the nanoparticle BiFe1-xZnxO3 (x = 0, 0.06, and 0.12) have a crystal structure of rhombohedral R3c. Through the FTIR test, it was observed that the area of wave number 491–569 cm-1 were used as an absorber for BiFeO3, while the one in zinc doped BiFeO3 were observed to be 489–636 cm-1. The VSM test shows that the BiFe1-xZnxO3 nanoparticles (x = 0, 0.06, and 0.12) have ferromagnetic properties and potentially change to paramagnetic properties with the addition of zinc doping. The VNA test were obtained, bismuth ferrite without doping has a reflection loss (RL) of –25.79 dB with a narrower frequency range and bismuth ferrite with zinc doping (%wt x = 0.12) has a RL of –30.02 dB with a wider frequency range so that zinc doped BiFeO3 potentially to be a good absorbent material.

We evaluate the reactivity of the Au surface towards H2 and compared the reactivity with Ag, Cu, and Pt surfaces. The reactivity is represented by the H2 dissociation energy over each surface. Their dissociation energies were calculated based on DFT calculation with PBE functional and PAW pseudopotential. The calculation results show that the Pt surface is the most reactive, followed by the Cu, Ag, and Au surfaces. The PDOS illustrates the d-band center is above Fermi level only on the Pt surface which indicates that it is the most reactive towards H2. The adsorbate charge shows that Cu donates the most electrons, trailed by Ag and Au. This study concludes that Au surface is the most inert among the other three metals. This inertness is a characteristic that defines a noble metal.

The power train efficiency of fuel cell vehicles (FCV) can be enhanced by improving the hydrogen energy utilization. Based on a mini FCV running on a 2 kW open-cathode Polymer Electrolyte Membrane (PEM) fuel cell, a waste heat recovery system design needs to be developed as an approach towards higher energy efficiency. The novelty of the system is on the integration of thermoelectric generator technology with hydrogen preheating process for a combined heat and power output. This manuscript presents the proposed integrated heat regenerator (IHR) designs, analysed using numerical computational modelling. Three IHR designs were proposed where the main design criteria are (i) a minimum of 10oC hydrogen preheating degree, and (ii) non-parasitic active cooling for the Thermoelectric generator (TEG) cells. Three design concepts were studied to identify its design and performance limitations. The numerical results were validated with theoretical modelling analysis for hydrogen exit temperatures and TEG surface temperatures. The analysis on predicted fuel cell power enhancement, TEG power generation and waste heat utilization were performed by relating the temperature profiles of the hydrogen reactant and TEG surfaces to fuel cell reaction models and TEG power relationships. A compact IHR design that produced 7.7 to 8 % total power enhancement and suitable in size for a mini FCV was identified for future development works

Graphene is a prominent material in a wide range of applications, however, the gapless nature of graphene limits its great performance in certain applications, such as in optoelectronic and photocatalytic applications field. Opening the bandgap has become one of the focused studies on graphene material today. Here, we used density functional theory (DFT) calculation to investigate the bandgap opening of bilayer graphene by external electric field applying. The calculation was performed on hexagonal stacked bilayer graphene structure using three different approximations and functional DFT; that is generalized gradient approximation (GGA) PBE and PW-91, as well as Local-density approximations (LDA) -CAPZ. The external electric field varied from 0.0 to 0.5 eV/Å/e in various electric field directions. The calculations results shows that the external E-F applied in perpendicular direction open the bandgap almost 4-times than non-determined the electric field direction. The bandgap opening by LDA functional calculation perform smaller bandgap opening compared to GGA calculation results, while the PBE and PW-91 of GGA produced similar values at low electric field applied. The larger bandgap of 0.80 eV obtained at 0.3 eV/Å/e electric field applied calculated with both GGA functional At 0.5 eV/Å/e electric field applied, bandgap with GGA-PBE almost zero, and the crystal structure changed from cubic to triclinic with layer position become apart.

In certain environments like condominium complexes, couriers are only allowed to drop off their payloads at designated drop-off stations instead of delivering it directly to the recipient. These regulations have become increasingly popular in condominiums during the Covid-19 pandemic, in part due to government SOPs encouraging their adoption. A partially automated delivery system using robot couriers that deliver the payloads from the drop-off stations directly to the recipient is developed. The system is made up of a central PostgreSQL database, a Webots simulated delivery robot and two Android applications for interfacing with the system. Two individuals operate the system: the system operator and the resident requesting delivery. The resident sends their delivery requests using the Resident android application. The system operator acknowledges the delivery requests, then loads the robot and configures it to carry the package(s) up to the resident’s housing unit through the Operator android application. Navigation and obstacle avoidance are achieved through usage of the A* pathfinding algorithm. To receive the package(s) once the robot arrives, a QR code enabled compartment on the robot is unlocked using the Resident android application once again. The PostgreSQL database and Advantech WISE-PaaS Dashboard are used to display delivery requests, residents’ data and robot status for system operators. NodeRED and MQTT are used to facilitate communications between robot, applications and database. In the end, the simulated robot is able to navigate a virtual environment with minimal faults and communicate properly with the applications and database. Robot speed is set at 0.27 ms-1 when empty, and maximum carrying weight is tested to be 20.5 kg with a delivery time of 1549 seconds for the arbitrary simulated delivery route.

Da’wah is an important effort in the spread of Islam. Every Muslim individual has the responsibility to carry out the da'wah of Islam through various means according to his ability. The scholars have also outlined guidelines in preaching which is an interpretation of the example of the sunnah of the Prophet SAW and the verses of the Qur'an. Through this da'wah effort, it is also possible to guide individuals whose hearts are softened to embrace Islam and leave other religions. This group is called a convert and belongs to eight categories that receive zakat assistance. The Johor Islamic Religious Council MAINJ sets a person who has just converted to Islam within a period of 10 years as a convert before being recognized as a mukalaf. During this period, various forms of assistance and facilities were provided to the converts to strengthen their ability to continue their Muslim life. However, with all forms of assistance provided, there are converts who are involved in social problems, crime, emotional stress and apostasy applications that reflect the inability to lead a Muslim life. Religious life or religiosity is very important in one’s life and exerts a great influence on one’s personality, actions and way of thinking. This situation raises the question of what is the role of the preacher on the level of religiosity of the convert and where is the level of religiosity of the convert at present. Based on these questions, this study was conducted by identifying the role of preachers towards converts and studying the appropriate measurement of religiosity for converts in Johor. This study is a qualitative study using content analysis method on the highlights of previous work. The findings of the study clarify the role of preachers and show the Muslim Religiosity Model, which is used as the basis for building an inventory of Muslim religiosity-personalities is suitable for use to converts by adhering to the basic principles in measuring religiosity. These findings can be used as a guide in studies related to the measurement of the religiosity of converts.

New Technology-Based Firms (NTBFs) are one of the key actors within the National System of Innovation. They are firms/businesses based on the exploitation of an invention and they play crucial roles in the processes of bringing new ideas or innovations to the market and by extension, contributing to economic growth. This paper provides empirical evidence on the emergence and performance of NTBFs in Nigeria. A survey design was used to collect data from NTBFs in the selected Technology Incubator Centres (TICs). Data were analysed using both descriptive statistics and the ordinary least square technique. The research results show that research and development (R&D) activities are vital for the growth and development of NTBFs, but this activity is still at a very minimal level. Product price, the number of employees, research and development, access to credit facilities, and the cost of raw materials are statistically significant in explaining the performance of NTBFs. The recommendations for ensuring the improved performance of NTBFs in Nigeria include the increased collaboration among NTBFs, universities, and research institutes, firms to spend at least 40 percent of their profit on research and development that relates to the improvement of their products, and the improvement in the level of the production process to enhance productivity and competitiveness.

Farklı yönetimler, rejimler ve durmaksızın değişmekte olan bir dünya ortamını kapsayan yüz yıllık bir sürenin tümünün bir yazı çerçevesinde incelenmesi fazla iddialı gelebilir. Hele konu, bazen birkaç yılda bir değişen büyük şehirlerimizin ulaşım politikaları olursa… Bu nedenle yazı, İstanbul’un Aksaray semtinin ulaşım tarihine odaklanarak başlamakta, ilk olarak 20. Yüzyılın başlarından 1970’lere kadarki gelişmeler özetlenmektedir. Bu çerçeve içinde, Tarihi Yarımada’da çoğu bilinçsizce hayata geçirilen yol projelerinin yıkıcı sonuçları da göz önüne serilmektedir. Bu yıllardan itibaren dünyada ulaşım politikalarında ortaya çıkan çağdaş anlayışların kısa bir özetinin ardından, Ankara ve İzmir de dahil, Türkiye’nin üç büyük kentinde yürütülen ulaşım politikaları incelenmektedir. Bu dönemde birkaç yerel çağdaş uygulama dışında, büyük kentlerde eski anlayışın sürdüğü görülmektedir. Devamında, bu şehirlerde 1990’lardan günümüze kadar uygulanmış olan ulaşım proje ve önlemlerinin, dünyada kabul görmüş genel ölçütler çerçevesinde değerlendirmesi yapılmaktadır. Makale, pandemi koşulları sona erdiğinde, çağdaş ulaşım politikalarını oluşturan nedenlerin hala geçerliğini sürdüreceğini ve bunlara her zamankinden daha fazla ihtiyaç duyulacağı görüşü ile sona ermektedir.

Alibis of Exclusion: The role of ethnic economies in the differentiated inclusion of refugees in Berlin
Authors: Sohail Jagat
Published: July 2022

Neoliberal transformations in the field of asylum in Germany have, since 2016, placed an emphasis on labour market participation as the primary way through which refugees can establish long-term residence claims. Yet, while new arrivals are increasingly expected to rapidly integrate into this market, they are often armed with differential and precarious legal statuses which overwhelmingly determine the spheres of economic activity refugees are able to participate in. This is especially true for the ever-increasing number of rejected asylum seekers who are temporarily “tolerated”, and for whom the only path to residence requires that they display their value as economic subjects to the German state. Based on ethnographic fieldwork conducted in Berlin between 2017 and 2020, I argue that, armed with little other than their cultural identities and networks, refugees seem to find themselves in co-ethnic economic spaces, displacing the management of new diversity to ethnic economies, and disavowing marginalising consequences of the neoliberal transformations refugees are subject to. By masking a relationship between recently arrived migrants and the German economy and society as a relationship between migrants themselves, I argue that these practices work as alibis of exclusion.
PEMIKIRAN HUKUM ISLAM MODERN
Authors: Berutu Ali Geno
Published: July 2022

Dalam sejarah pemikiran hukum Islam, senantiasa terjadi proses dialektika tesis, antitesis dan sintesis antara para pemikir dan cendekiawan Muslim, sehingga peluang untuk melakukan kerja keilmuan terus terbuka bagi mereka yang memenuhi kualifikasi. Sebuah pemikiran sejatinya lahir dari sebuah proses berpikir yang dilatarbelakangi oleh setting sosio-politik yang melingkupinya. Dalam studi Islam yang menggunakan pendekatan sosio-historis, sebuah pemikiran, gagasan, ide atau pandangan tertentu terhadap sebuah fenomena yang hidup harus dilihat sebagai respon intelektual seorang pemikir terhadap fenomena sosial kemasyarakatan dan problem-problem politik yang dihadapinya. Secara historis, proses dialektika pemikiran Islam mulai tumbuh sejak awal kelahiran Islam, dimana Rasulullah SAW dan para sahabatnya membangun peradaban Islam gemilang yang berdiri bersandingan dengan kekaisaran Romawi yang telah lebih dulu ada. Bahkan pada gilirannya, peradaban Islam melebihi peradaban bangsa Romawi, yang mulai redup cahayanya. Hal ini terus berlangsung sampai munculnya para ilmuwan dan cendekiawan Muslim kenamaan yang bisa dikategorikan sebagai pemikir.
Vehicle Stability Control

Vehicle Stability Control (VSC) adalah sebuah fitur keamanan mobil yang diciptakan untuk mendeteksi dan mencegah overster, understerr dan sliding pada ban mobil saat mobil melaju di tikungan atau saat tergelincir. Teknologi ini di ciptakan pada akhir 1980-an, berkolaborasi dengan Daimler AG dan perusahaan induk Mercedes-Benz. Kemudian, pada tahun 1992, pemasangan untuk pertama kalinya di S-Class 1995. Ini adalah variasi tertinggi dalam jajaran S-Class pada saat itu, dan hanya tersedia pada sedan dengan mesin V12. Tujuan utama VSC adalah menjaga kendaraan tetap stabil dan berada di jalur. Sistem VSC akan aktif secara otomatis ketika ban mulai meluncur atau kehilangan traksi karena permukaan jalan yang licin atau berpasir. Kuncinya adalah membatasi transfer tenaga mesin ke roda sambil juga mengaktifkan rem agar ban tidak slip. VSC mempunyai 5 komponen utama dan sangat penting, yaitu switch base and steering angle sensor, stoplamp switch, ECU VSC, EFI ECU, dan vehicle speed sensor.
The Effect of Altering Food Packaging Size on Expected and Perceived Satiation
Authors: Buckingham Gavin
Published: July 2022

The purpose of this study was to investigate the effect of changing a food’s packaging size on the perceived weight, expected satiation prior to eating, and perceived satiation after eating of that food. It was hypothesised that a smaller bag would be perceived to be heavier (in accordance with the size-weight illusion, SWI), and would be expected and perceived to be more satiating. Participants (N=51) were presented with a large and a small foil bag with the same amount of food inside. They provided ratings of how heavy they perceived each bag to be, how much they expected each bag to fill them up, and how full they felt after eating each bag. Results showed that the smaller bag was perceived to be heavier (p = .001), confirming that the SWI had occurred. The difference in packaging size was not found to have a statistically significant effect on expected or perceived satiation (p > .05 in both cases). It was concluded that changing a food’s packaging size can affect our perception of the food’s weight, but not satiation.

Authors: Guanoluisa Chicaiza Sharon Domenica , Arráiz de Fernández Carolina
Published: July 2022

Introduction: The global concept of professional quality of life (QOL) is complex. It involves characteristics of a work environment, personal characteristics of the individual and the professional's exposure to primary and secondary traumas in the work environment. Objective: To determine the quality of work life of rotating nursing interns in pre-professional practice. Methods: A quantitative, cross-sectional and correlational research was carried out for the period from September 2021 to January 2022. The CVP-35 Questionnaire was used, which has an overall reliability of 0.90. The subscales of each dimension have a high internal consistency (Cronbach's ? between 0.75 and 0.86). Results: The comprehensive analysis of the CVP-35 Questionnaire in the rotating interns showed 55.4% for the managerial support factor, 68.3% for the work demand factor and 98%. Regarding the quality of working life, a predominance of high quality of life was demonstrated with 55 (54.5%), followed by a similar predominance of the average quality of life with 46 (45.5%) and none presented low quality of life. Conclusions: The quality of work life of rotating nursing interns, in their pre-professional practice, is high. Half presented an average quality of life for the managerial support factor. More than half of the interns reached an average quality of life for the work demand factor and finally almost all of the nursing interns present a high quality of life for the intrinsic motivation factor.

The most prevalent metabolic and endocrine perinatal issue is gestational diabetes mellitus (GDM), which is an increasing health problem worldwide. It is a controversial entity, with conflicting guidelines and treatment protocols. In the United States, most doctors utilise a two-step strategy, first with a 50-g non fasting oral glucose challenge test at 24 to 28 weeks and then a 100-g fasting test for women who have a positive screening result. Alternatively, Clinicians take a one step Diabetes in Pregnancy Study Group India (DIPSI) method and perform simply a 75-g two hour fasting oral glucose tolerance test. The DIPSI approach of antenatal GDM screening has been demonstrated to be straightforward, cost effective, easy to use, patient friendly, and convenient. When comparing the findings to the gold standard of the International Association of Diabetes and Pregnancy Study Group (IADPSG), DIPSI shows high specificity and acceptable sensitivity. To maintain euglycemia, glucose monitoring, dietary changes, exercise, and, if necessary, medicines are used. Although insulin therapy is the most common treatment, glyburide and metformin may become more popular. Prenatal testing with nonstress tests and amniotic fluid indices, commencing in the third trimester, is commonly used to assess foetal well-being in women undergoing medication. The delivery technique and time are contentious. Women who have gestational diabetes are at a significant risk of developing type 2 diabetes later in life. As a result, along with routine diabetes screening, lifestyle adjustment should be recommended.

Authors: Gauchan D. , Joshi B.K. , Sthapit S. , Jarvis D.
Published: July 2022

Traditional crops play an important role in household food security and livelihood needs of mountain communities, while at the same time safeguarding crop biodiversity for future generations. This study aims to analyse socioeconomic, farm-specific agro-ecological and market factors influencing cultivation and maintenance of crop diversity in Nepal. It used sample surveys of 328 households from mountains of Humla, Jumla, Lamjung and Dolakha districts in 2015. The sample survey was supplemented with participatory rural appraisals, field monitoring visits and local stakeholder consultations. Tobit regression model was used to assess factors driving household decisions to allocate area for production and maintenance ofon-farm diversity. Farm maintenance of crop diversity was related to household food sufficiency level of traditional crops. Factors influencing on-farm crop diversity and household food security varied with the crops, and mainly related with farmers’ age, family size, farm size, agro-ecosystem and market factor. Future research and development interventions need to focus on diversity rich solutions and technologies tailored to specific crops, socioeconomic, market and farm-agroecology of the households enhancing household food security and management of mountain crop biodiversity.
Modelling habitat suitability of the Himalayan monal (Lophophorus impejanus) and its connectivity in the Himalayas
Authors: Baral Suraj
Published: July 2022

The Himalayan monal Lophophorus impejanus is a montane bird exhibiting a seasonal migration to avoid harsh winter. However, the knowledge of the suitable habitat and level of connectivity across the range for the species is not available. To close this knowledge gap relevant for the species' conservation, species distribution modelling with presence-only data and relevant environmental variables was used to determine the range-wide distribution of the species. The distribution of the species is mainly constrained by habitat and climatic variables. The connectivity of the species was modeled using the distribution model output. The study presented a currently contiguous area of suitable habitat available for the species that are well connected with evidence of metapopulation in the range edges. The study also found that the current network of protected areas is not sufficient to ensure the connectivity of the species. Conservation of the currently suitable habitat is necessary to ensure the species is conserved.
Birds and habitats recorded in the lower Mai Valley Important Bird and Biodiversity Area
Authors: Inskipp Carol , Acharya Sanjib , Giri Tikaram
Published: July 2022

A bird survey was carried out in the lower Mai Valley Forests (MVF) Important Bird and Biodiversity Area (IBA) in far eastern Nepal, between 180 m and 2200 m from 01 to 10 March 2022. An assessment was also made of the environmental conditions of forest and river habitats, and type and extent of agriculture. A comparison was made with a March 1981 visit. Observations were noted during a ten-day trek from Ilam (1205 m) up to Hangetham (2200 m) and down to Sukhani (180 m). The large number of 256 bird species was recorded, including one globally threatened and five globally near-threatened species, five restricted-range species, 20 nationally threatened and eight nationally near-threatened species. One new species for Nepal, black-breasted thrush Turdus dissimilis and three rare Nepal species not found in the IBA for at least 20 years, were also recorded. Extensive intact areas of semi-evergreen subtropical and lower temperate mixed broadleaved forests valuable for birds still remain. Tropical forests have been fragmented and mainly replaced by tea and rubber plantations, and also by the spread of agriculture. However, Sukhani still comprises a substantial semi-evergreen broadleaved forest important for birds, although it is highly threatened. Hunting is probably a significant threat to bird species in MVF. Despite loss and degradation of some forests, especially in the tropical zone, MVF still qualify as an IBA. The Mai Khola habitat has been severely damaged by the Mai Khola Hydroelectric Project, which became operational in 2015, resulting in serious declines in river birds. MVF remain outside the existing protected area network. Including MVF in Nepal’s protected area system would ensure conservation of the species-rich semi-evergreen mixed broadleaved tropical and subtropical forests that are currently an important omission. Further bird surveys are recommended at all elevations and in tropical and subtropical forests that have so far not been covered.

Authors: Kozlova I. I.
Published: July 2022

The researches were held in 2011-2019 on the base of strawberry experimental sites in the Experimental Production Association of the I. V. Michurin Federal Scientific Center (Michurinsk, Tambov Region, RF). The purpose of the research was to identify criteria and parameters for evaluating strawberry varieties suitable for integrated cultivation technology, and to improve the commercial assortment. Plants of 45 introduced varieties were studied in strawberry plantations established in 2010-2016. The results of the analysis of the Register of strawberry varieties allowed for use on the territory of the Russian Federation and the region are presented. The principal problems of improving the assortment of strawberry are shown taking into account different cultivation systems. On the base of system analysis of experiment results main criteria and parameters were indicated. They allow us to evaluate the strawberry varieties suitable for the system of integrated production. The folloving sequence for evaluating strawberry varieties is recommended: adaptive capacity (abiotic, biotic and edaphic factors), commercial quality, transportability, productivity, consumption qualities marketability at post-harvest period, season of ripening; simultaneous ripening and number of harvesting. Introduced strawberry varieties have been identified that meet the parameters of the developed assessment, which formed the basis of an commercial assortment suitable for the integrated fruit production system. These are varieties with ripening dates: very early ('Flair', 'НФ311), early ('Elianneу', 'Maya', 'НФ 421', 'Fleurette'), medium ('Isaritsa', 'НФ 205', 'Marmolada', 'Vima Xima'), late ('Florence', 'Malwina'), very late ('Flamenko', 'Monterey', 'San Andreas'). They make it possible to significantly expand the period of strawberry production with high marketability, which is expressed in an increase in the share of the output of products of the highest and first commercial varieties during the life of the plantations (65-90 %).

Studies of the strawberry economic and biological parameters were carried out in the Orenburg branch of the Federal Research Center of Horticulture from 2019 to 2021. The objects of the study were varieties of foreign breeding. The zoned varieties Orletz and Zenga Zengana served as control. According to the main phenological phases of plant development, there was a difference in the onset of the flowering phase, in the observed varieties it was 3 — 5 days. The total duration of flowering on average ranged from 10 to 12 days. The beginning of berry ripening in the Orenburg region in early varieties occurs in the first decade of June, in middle repining varieties in the second decade of June. The average duration of the fruiting period was 12-21 days. According to winter hardiness, the most resistant during the observation period from 2019 to 2021 were the zoned varieties Orletz and Zenga Zengana, among the varieties of foreign breedig Bogota, Bounty, Venta, Ducat, Lord, Polka, Troubadour, Junia Smides. Over the years of research, strawberry mite damage was noted up to 1 point, on varieties: Florence, Honeoye, Corona, Rumba, Sonata, Troubadour, Bounty. White spotting was noted in 2019 on the varieties Polka, Vima Xima, Corona, as well as in the Zenga Zengana zoned variety. Brown spotting in a weak degree from 0.5 — 1 points affected all the studied varieties. On average, over 3 years of observation, the number of peduncles in early ripening varieties was 4 pcs.; for varieties of the average ripening period — 4-6 pcs. On the studied strawberry varieties, the number of berries ranged from 14 to 28 pcs./ bush. According to the yield assessment, the studied strawberry varieties Junia Smides, Bogota, Polka and Zenga Zengana are medium-yielding — more than 12 t/ha.

Abstract : Way Sekampung Dam is built to optimize the utilization of the Way Sekampung watershed. It is classified as an embankment dam with upright core which is following with a high risk of failure. The research of dam slope stability become an effort to fulfill dam safety. This study is based on the effects of seepage and seismicity. The seepage review is focused on what is the safety of the dam against potential piping, while for seismicity it is carried out under earthquake loading which using a modified earthquake coefficient approach. Based on the calculation of the seepage modeling using SEEP/W at the flood water level (FWL) and normal water level (NWL) obtained a value of the calculated safety factor (SFcal) of ≥ SFmin = 4 and, it can be said to be safe against piping. Slope stability modeling with SLOPE/W at post construction, flood water level (FWL),normal water level (NWL), and low water level (LWL), under earthquake loading conditions, it is found that the calculated safety factor (SFcal) varies in each loading condition.  In the OBE loading conditions; the calculated safety factor value (SFcal) is greater than SFmin, indicating that the slope stability at the Way Sekampung Dam is safe. The simulation with MDE loading conditions, show results of the dam slope stability modeling in several variation resulted in SFcal < SFmin. This shows that the slope stability at the Way Sekampung Dam is not safe, have the potential to experience damage and collapse. Keywords: embankment dam, slope stability, seepage, earthquake, SEEP/W and SLOPE/W
