Membrane structures: application experience and development prospects
Authors: Tusnin Alexander R. , Postarnak Mikhail V.
Published: April 2023

Introduction. At present, studying an increase in the applicability of steel structures in all segments of the construction industry, particularly in residential construction, is relevant. Membrane systems are high-tech and economical structures. The behavior of large-span membrane structures is studied in great detail in practice. However, membranes, combined with medium and small spans, remain understudied.

Materials and methods. Findings of basic theoretical, experimental and numerical studies of membrane systems, used in structural analysis and design, are provided. An advanced membrane slab design, designated for metal-framed multistory residential buildings, is described. Its flat support contour is rectangular in plan; it has a membrane and a monolithic concrete slab over it.

Results. Lira-SAPR software package was used to conduct numerical studies of the membrane slab. The studies took account of its structural, geometrical and physical nonlinearity, and the results were compared with an experimental study. The distribution of forces in its support contour is typical for rectangular membrane structures with positive curvature shells.

Conclusions. Numerical analysis of a full-scale structure and a tested model having a monolithic reinforced concrete slab on the membrane proved the long-term benefits of this structure. The results of numerical analysis demonstrate the qualitative convergence with the experimental data. The variable thickness of the slab resting on the membrane, collaboration of the slab, the membrane and the support contour, the physical nonlinearity of the system elements and, above all, the reinforced concrete slab must be taken into account to reduce the qualitative discrepancy between numerical and experimental results.
Factors that influence deformation properties of heavy concretes containing alkali-activated cements
Authors: Salamanova Madina Sh. , Murtazaev Said-Alvi Yu.
Published: April 2023

Introduction. In the process of structurization, development of properties, and operation concrete structural elements undergo various linear and volumetric changes, triggered by material deformations. Therefore, it is the deformation properties that are taken into account when design documentation is drafted at the stage of making design solutions with regard for the influence of this factor on physical and mechanical characteristics of a final reinforced concrete product or a monolithic structure as a whole. Of particular interest are causes of deformations that emerge during the curing of concrete composites.

Materials and methods. Deformation properties of heavy concretes, having binders that contain alkaline mixes, were studied in accordance with GOST 24452–80 Concrete. Methods for determining prism strength, modulus of elasticity and Poisson’s ratio, and GOST 17624–87 Concrete. Ultrasonic method for determining strength.

Results. The paper presents studies focused on deformation-triggered changes. The results showed that the development of deformations was observed during the hardening of concrete prisms, and shrinkage deformations were characteristic of concrete compositions that contained the micro-filler made of opoka malmstone, while compositions, having a dune powder additive, demonstrated slight expansion.

Conclusions. Deformations of concrete, containing such binders as mineral powders of aluminosilicate origin and activated by an alkaline solution, were studied to identify the nature of ongoing deformations. Hence, in case of the surface contact between concrete and the environment, shrinkage deformations are caused by moisture, carbonization and some contraction processes that manifest their characteristic features. In the absence of contact with the gas-air medium, deformations caused by contraction processes are clearly manifested. It is noteworthy that numerical values of shrinkage deformations are below the standard values for Portland cement heavy concrete.

Published: April 2023

Introduction. the development analysis of domestic residential building construction of volumetric blocks, starting from the 60s of the twentieth century to the present time, is given. It is noted the innovative nature of the transition from low-

volume blocks to large-sized blocks of high and full factory readiness. The problems that have arisen in this case are indicated, of which one of the most acute is the determination of organizational and technological parameters for the construction of residential buildings.

Materials and methods. the role of organizational and technological parameters of the objects’ construction is described — the duration of construction and its stages, the complexity of work, the number of workers. The content of the timing carried out by the MonArch Group of Companies for the installation of large-sized volumetric blocks of a four-story residential building in Yakovlevo–2 village (New Moscow) is revealed. The main installation operations are analyzed with an indication of the time spent on each floor and the roof arrangement.

Results. based on the final results of the timekeeping materials generalization, three estimates of the duration of a building construction of large-sized blocks are proposed — pessimistic, satisfactory, optimistic. The found dependences “duration of building construction — the number of large–sized blocks installed taking into account the roof arrangement” are revealed with the corresponding calculation formulas. The formula for calculating the labor intensity of installers work and crane maintenance workers is also given.

Conclusions. the prospects for the innovative technology development for the construction of residential buildings of large-sized blocks are substantiated, provided that capital investments are allocated and the efforts of research and design organizations are combined to comprehensively solve the problems that have arisen. To solve the problematic tasks of determining the indicators of organizational and technological parameters of buildings construction of large-sized blocks, an approach and methods for assessing the duration of construction and the complexity of installation work on the assembly of buildings are proposed.
Between Taoism and Confucianism: tendencies in lyric poetry of the Western Jin period
Authors: Malakhevich Daria E.
Published: April 2023

The author argues that the coexistence of Taoism and Confucianism in the historical arena of the Western Jin dynasty led to the fact that literati in their works moved from one “end of the spectrum” to another, reflecting both the unity and opposition of these two areas of philosophical thought. Contrary to popular belief, the xuanxue philosophy did not replace Confucianism as the leading ideology, but coexisted with it. This symbiosis also led to the emergence of a “dual role” for the literati of the period in question: in their work, a poet could act both as a Confucian scribe and as a hermit, filling the poem with relevant motifs. The author provides an overview of the main trends in the poetry of Western Jin era, leading to the conclusion that the interaction of Confucianism and Taoism as the two “ends of the spectrum” of consciousness of early medieval Chinese literati. The social and political context of the era, the main ideological currents in literature and their embodiment in the poetry of the Western Jin period (265-316) are considered. The academic novelty and value of this work are due to the insufficient study of the literature of this period, not only in Russian but also in world Sinology.

Aproximaciones al conflicto armado en Colombia y sus implicaciones en la construcción de subjetividades una mirada histórica y psicosocial
Authors: Forero Jymy
Published: April 2023

La relación entre violencia, política y economía ha sido suficientemente estudiada en Colombia abriendo un debate prolijo en torno a los orígenes, características, modalidades y motivaciones de la “violencia” así como a sus métodos de investigación. Sin embargo, dichos estudios no han reparado suficientemente en su relación con la construcción de subjetividades. El objetivo del presente artículo es presentar, desde un enfoque de abordaje de la historia crítica y del tiempo presente, una reflexión de tipo analítico sobre el decurso de la guerra en nuestro país, en particular de las tres últimas décadas, advirtiendo algunas implicaciones psicosociales. El desarrollo de la tesis central girará en torno a dos elementos: de un lado, la violencia que actualmente vive el país tiene un carácter estructural de tipo político y social que se reproduce permanentemente incidiendo sobre el conjunto de la sociedad, y de otro lado, como parte del sostenimiento del estatus quo, la guerra psicológica usada como estrategia de dominación por parte de los sectores dominantes, ha estado involucrada de manera significativa en la construcción de los sujetos y subjetividades sociales y políticos.

Arthropods account for a large proportion of animal biomass and
diversity in terrestrial systems, making them crucial organisms in our
environments. However, still too little is known about the highly
abundant and megadiverse groups that often make up the bulk of collected
samples, especially in the tropics. With molecular identification
techniques ever more evolving, analysis of arthropod communities has
accelerated. In our study, which was conducted within the Global Malaise
trap Program (GMP) framework, we operated two closely placed Malaise
traps in Padang, Sumatra, for three months. We analyzed the samples by
DNA barcoding and sequenced a total of more than 70,000 insect
specimens. For sequence clustering, we applied three different
delimitation techniques, namely RESL, ASAP, and SpeciesIdentifier, which
gave similar results. Despite our (very) limited sampling in time and
space, our efforts recovered more than 10,000 BINs, of which the
majority are associated with “dark taxa”. Further analysis indicates a
drastic undersampling of both sampling sites, meaning that the true
arthropod diversity at our sampling sites is even higher. Regardless of
the close proximity of both Malaise traps (< 360 m), we
discovered significantly distinct communities.

Published: April 2023

Soil fungi are involved in the decomposition of organic matter, alter
soil structure and physicochemical properties and drive the material
cycle and energy flow in terrestrial ecosystems. Grazing exclusion is
one of the most common measures to restore degraded grasslands
worldwide. However, changes in soil fungal community characteristics
during grazing exclusion in different types of grasslands are unknown,
and in particular, there is a lack of experimental evidence on the
effects of grassland type and grazing exclusion on soil fungal
diversity. Here, we investigate the effects of a 9-year grazing
exclusion on soil properties, fungal community composition and diversity
in three grassland types (Temperate desert, Temperate steppe and
Mountain meadow). The results showed that soil fungal community
composition differed between grassland types, and that grazing
exclusion, grassland type and the interaction between the two did not
significantly affect soil fungal α-diversity and composition, but
significantly altered fungal β-diversity. Overall, our results highlight
the importance of soil nutrient content on fungal diversity,
particularly soil total nitrogen, total phosphorus and organic carbon,
and provide key evidence to reveal the mechanisms by which soil fungi
respond to grazing exclusion in different grassland types.

The study was designed to determine the prevalence and epidemiology of
SARS-CoV-2 variants during the fifth wave of COVID-19 in selected
districts of Punjab, Pakistan. The nasal swab samples (n=708)1 of
suspected patients from various districts across Punjab were collected
between December 2021 to April 2022. The genome extraction was done
using an auto-extractor (Uni-medica) in the BSL-3 facility.
Reverse-transcription real-time polymerase chain reaction (RT-PCR) was
employed for viral detection and quantification. For the identification
of SARS-CoV-2 variants, various mutations of spike protein were targeted
using Multiplex PCR. The study’s results revealed the Omicron variant of
concern (VOC) as the prevalent lineage of SARS-CoV-2 circulating in the
selected regions of Punjab at the time of sampling. The VOC accounted
for 90.01% of COVID-19 cases, followed by Delta (6.81%) and wild
variant (3.80%). Prevalence of Omicron (VOC) was recorded higher in men
(47.96%) as compared to women (42.05%). In addition, the highest
percentage of VOC was observed in adults (47.39%) as compared to older
people (32.07%) and young people (10.55%). This study highlighted the
circulation of the Omicron variant during 5 wave of
COVID-19 in Punjab Province, Pakistan.
Comparison of tip positions determined by two types of maximal P wave during intracavitary electrocardiography (IC-ECG) guided venous port catheter insertion through the right internal jugular vein
Authors: Fan Boqiang , Jia Jian , Xiang Lei
Published: April 2023

Objectives: To evaluate the difference of tip position
determined by two types of maximal P wave of intracavitary
electrocardiography (IC-ECG). Patients and methods: Patients
with two major types of maximal P wave were allocated into two groups
(P-max and P-alter). Tip positions were recorded on computed tomography
(CT) and chest X-ray (CXR). Demographic data, procedure time, catheter
length, and final tip position were recorded and analyzed.
Results: Two hundred and twenty patients were included, and 203
patients were eligible for final analyses. Maximal P wave may sustain
for several centimeters (0-3 cm). Tip position determined by P-alter
were mostly in upper atrium (80/102), and tip position determined by
P-max were mostly on cavoatrial junction (52/101). Tip may move cephalad
with patient’s position changed from supine to upright.
Conclusion: Tip positions determined by P-alter were mostly in
upper atrium, however both criteria are acceptable for tip positioning.
Post operative imaging for tip position would better use CT. CXR may
underscore catheter position determined by IC-ECG.
Inferring drivers of nitrate and sediment event dynamics from hysteresis metrics for two large agricultural watersheds
Authors: Bolade Oladipo , Hansen Amy
Published: April 2023

Excess nitrate and sediment, mobilized by precipitation events and
transported into surface waters, is a global water quality challenge.
Recent advances in high frequency, in-situ water quality monitoring
sensors have created opportunities to investigate constituent
concentration dynamics during short-term hydrological changes. In this
study, we characterized the event-scale variability of nitrate ( NO 3 -
  ) and turbidity (a surrogate for sediment transport) in two large
agricultural watersheds of the Upper Mississippi River Basin using
hysteresis loop characteristics to determine sources and dominant
transport mechanisms. We then applied factor analysis to detect variable
groupings and thus determine controls on nitrate and sediment dynamics.
We found that NO 3 -   hysteresis behavior was consistent between the
two watersheds and demonstrated distal contributions and/or late-event
mobilization and flushing that was controlled by the characteristics of
the event hydrology (such as, event duration and magnitude of event
discharge). In contrast, turbidity hysteresis loops indicated sediment
delivery differed between the two watersheds; the smaller watershed with
more diverse land use demonstrated consistent early-event flushing or
rapidly responding pathways whereas the larger, more agricultural
watershed showed variability between dilution vs. flushing as well as
delivery pathways between events. This dynamic behavior as well as the
magnitude of the hysteretic response was principally related to the time
lag between turbidity and discharge peaks for the smaller site, and to
the event peak discharge and subsequent stream erosive power at the
larger site that switched behavior. This result is critical for
watershed water quality management especially in the context of a
changing climate and further underscores the utility of high-frequency
sensors monitoring data to offer deep insights into hydrological
processes controls on contaminant transport and delivery.
Investigating the Effects of Uniaxial Pressure on the Preparation of MgTiO3-CaTiO3 Ceramic Capacitors for MRI Systems

Published: April 2023

Today’s healthcare system relies on MRI (medical resonance imaging) for
early diagnosis and treatment planning. For open MRI systems to achieve
resolutions of about a hundred microns, a high voltage is required, as
well as a specialized power supply. NP0 (Negative-Positive-Zero) ceramic
is selected for the fabrication of adjustable capacitors. Specifically,
it stands for which is a classification based on the temperature
coefficient of capacitance (TCC) of the ceramic material used in the
capacitor. NP0 capacitors have a TCC of 0 ±30 ppm/°C, which means that
their capacitance value does not change significantly with temperature
and frequency. They are known for their stability and low losses, making
them ideal for applications that require high accuracy and reliability,
such as timing circuits for RF applications. In this paper, MgTiO-CaTiO
ceramic is used to make an adjustable capacitor with desired properties
for MRI systems. To enhance the dielectric properties of MgTiO3
ceramics,CaTiO3 was added in varying concentrations. After pressing and
sintering, the resulting samples were tested using a vector network
analyzer in the frequency range of 10 MHz to 130 MHz.The adjustable
capacitor fabricated using high co-fired NP0 ceramic may have been used
for MRI applications such as tuning circuits and matching networks,
where precise capacitance values and low loss are critical[1]. MRI
systems with resonance frequencies of 128 MHz require trimmers with
ceramic cores.

The paper presents natural and cultural historical values and rarities of the
Tara Na?tional Park, whose significance in the ecosystem and cultural terms
exceeds national borders. Special emphasis is placed on forest ecosystems,
the state of which is shown through a series of elements. Starting from the
current state of forests, on the one hand, and the functionally optimal
state, on the other hand, general and special management objectives
dominated by the protective component are defined. All objectives are of
equal importance and, mainly, of a long-term character. Their realization
depends, among other things, on the degree of dispro?portion of the initial
and optimal-target state. The realization of goals is achieved by a set of
management measures, which are grouped into silvicultural and management
measures, with special attention paid to the values of the felling ripeness
diameter in the forests of fir, beech and spruce, as the most prevalent
categories of forests. It was noted that the management of forests of the
Tara National Park has mostly maintained and improved all forest functions,
while at the same time striving to achieve the maximum possible production
of wood volume of the best quality. In the future, in accordance with the
control method of management, further permanent monitoring of National Park
forests is necessary, timely reaction to the prevention of all negative
trends in their development, intensification of scientific research in all
segments of management, as well as review of the impact of passive
protection of certain parts of the complex on the state of forests and the
values that are protected.
POTENSI INHIBITOR SENYAWA PADA SUKUN (Artocarpus altilis) TERHADAP PROTEIN POLY (ADP-RIBOSE) POLYMERASE 2 (PARP2) PADA KANKER OVARIUM DENGAN MODEL MOLECULAR DOCKING

ABSTRACT

Ovarian cancer is the third leading cause of cancer death in Indonesia. The mechanism of cancer needs to be understood to create drugs that play a role in inhibiting the development of cancer cells. PARP is a prime protein in cancer cell development. PARP is a target of chemotherapy, namely through its inhibition by 3-aminobenzamide compounds. Treatment using natural ingredients is safer than using synthetic drugs. Breadfruit (Artocarpus altilis) is a plant that grows in Indonesia. It is efficacious because it contains many compounds used in the manufacture of various types of drugs. The PARP receptor (3KCZ) was examined for the value of binding affinity with the flavonoid derivative ligands contained in breadfruit (Artocarpus altilis) using the help of the software Pyrx version 0.8. The test results showed tamoxifen (-8 kcal/mol), quercetin (-8 kcal/mol), cyclocommunal (-9.6 kcal/mol), morusin (-6.7 kcal/mol), and cyclomulberrin (-9 kcal /mol) have a lower binding affinity value compared to 3-aminobenzamide (-6.6 kcal/mol) which is the native ligand of PARP. These results prove that the flavonoid-derived compounds in breadfruit can potentially act as PARP inhibitors in ovarian cancer cells.

ABSTRAK

Kanker ovarium merupakan kanker penyebab kematian ketiga terbesar di Indonesia. Mekanisme kanker sangat perlu dipahami untuk menciptakan obat yang berperan menghambat perkembangan sel kanker. PARP merupakan protein yang berperan penting pada perkembangan sel kanker. PARP telah terbukti dapat menjadi target kemoterapi, yaitu melalui penghambatannya oleh senyawa 3-aminobenzamide. Pengobatan menggunakan bahan alami lebih aman dibandingkan penggunaan obat sintetis. Sukun (Artocarpus altilis) merupakan tumbuhan yang tumbuh di Indonesia yang berkhasiat karena mengandung senyawa yang dapat dimanfaatkan dalam pembuatan berbagai jenis obat.  Reseptor PARP (3KCZ) dilihat nilai binding affinity dengan ligan turunan flavonoid yang terkandung pada sukun (Artocarpus altilis) menggunakan bantuan softwere pyrx versi o,8. Hasil uji menunjukkan senyawa tamoxifen (-8 kcal/mol), quercetin (-8 kcal/mol), cyclocommunal (-9,6 kcal/mol), morusin (-6,7 kcal/mol), dan cyclomulberrin (-9 kcal/mol) memiliki nilai binding affinity yang lebih kecil dibandingkan dengan 3-aminobenzamide (-6,6 kcal/mol) yang merupakan native ligan dari PARP. Hasil ini membuktikan bahwa senyawa-senyawa turunan flavonoid pada sukun dapat berpotensi sebagai inhibitor PARP pada sel kanker ovarium.

In this paper, we introduce a two-strain SIR epidemic model with viral mutation and vaccine administration. We discuss and analyze the existence and stability of equilibrium points. This model has three types of equilibrium points, namely disease-free equilibrium, dominance equilibrium point of strain two, and coexistence endemic equilibrium point. The local stability of the dominance equilibrium point of strain two and coexistence endemic equilibrium point are verified by using the Routh--Hurwitz criteria, while for the global stability of the dominance equilibrium point of strain two, we used a suitable Lyapunov function. We also carried out the bifurcation analysis using the application of center manifold theory, and we obtained that the system near the disease-free equilibrium point always has supercritical bifurcation. Finally, the numerical simulations are provided to validate the theoretical results. Continuation of the supercritical bifurcation point results in two Hopf bifurcations indicating a local birth of chaos and quasi-periodicity.

The strategy to meet the water demands of Semarang and Demak Regencies involves enhancing the storage capacity of the Kedung Ombo Dam. This augmentation will inevitably alter the typical water level, thereby affecting the stability of the dam structure as it bears a greater load. Furthermore, the Kedung Ombo Dam, which is nearly 32 years old, necessitates re-evaluation since it lacks the full benefit of contemporary design methods. This study is confined to examining the slope stability, both static and pseudostatic, at a steady state flow, with the highest normal water level elevation (elevation +92.00) as the focal point. The slope stability analysis was conducted via the finite element method using the Slope/W in Geo-Studio software. The outcome of the static slope stability analysis indicates that the safety factor of the Kedung Ombo Dam body remains above the minimum allowable safety factor. In the pseudostatic analysis, the safety factor during the Operating Basic Earthquake (OBE) remains above the minimum allowable safety factor. However, during the Maximum Design Earthquake (MDE), the safety factor demonstrates a value that is lower than the minimum allowable safety factor. Nevertheless, the analysis of fixed displacement or permanent deformation reveals that the maximum settlement that occurs during the MDE earthquake does not exceed 50% of the available freeboard.

Bu çalışma Çorum ili İskilip Orman İşletme Müdürlüğü’ne bağlı Karmış Orman İşletme Şefliği sınırlarında gerçekleştirilmiştir. Çalışma farklı yükseltilerdeki (1000 m, 1553 m ve 1830 m) orman içi açıklıklarda yürütülmüştür. Bu alanlar aynı zamanda yerel halk tarafından mera olarak kullanılmaktadır. Bu çalışmanın amacı, bazı fiziksel ve kimyasal toprak özellikleri ile vejetasyon yapısının yükseltiye bağlı olarak değişimini belirlemektir. Çalışma için toprak örnekleri 2021 yılında alınmıştır. Toprak analizi için her çalışma alanından (0-15 cm derinlikten) 10’ar adet olmak üzere toplamda 30 adet toprak örneği alınmıştır. Tek yönlü varyans analizi sonuçlarına göre; ortalama toplam azot, organik madde, kil-kum içeriği, kireç içeriği, pH ve EC değerleri bakımından meralar arasında istatistiksel olarak anlamlı farklılıklar bulunmuştur. Toprak analiz sonuçlarına göre, 1000 m yükseklikteki toprakların çok az olan ortalama fosfor içeriği ve yüksek kil içeriği dışında toprakların fiziksel ve kimyasal özellikleri açısından bitkilerin büyümesini ve gelişmesi engelleyici ciddi anlamda olumsuz bir faktör tespit edilememiştir. Varyans analizi sonuçlarına göre baklagiller, buğdaygiller ve diğer familyaların botanik kompozisyon değerleri yükselti bakımından istatistiki anlamda farklı bulunmuştur. Çalışma alanlarında vejetasyonun otlatma olgunluğuna ulaşmamış olmasına rağmen otlatma yapıldığı ve kritik otlatma dönemlerine dikkat edilmediği gözlemlenmiştir. Buna bağlı olarak hayvanlar açısından besleyici olan azalıcı mera bitkilerinin sayısı oldukça düşük bulunmuştur. Ayrıca alanlarda istilacı türlerden olan Ranunculus constantinopolitanus ve Dipsacus laciniatus’un yaygın olduğu belirlenmiştir. Otlatma alanlarından daha fazla bitkisel verim almak için erken ilkbahar, geç sonbahar ile kritik yaz otlatması periyotlarına dikkat edilmesi, ekosisteme uygun azalıcı türler ile üstten tohumlama yapılması ve yabancı otlarla mücadele edilmesi önerilmektedir.

Halal Tourism: The Existence of One Village One Product-Based Cultural Tourism Development in Banyumas Regency
Authors: Sochimin
Published: April 2023

This study aims to identify the prospects and existence of cultural tourism in Banyumas Regency with the concept of One Village One Product (OVOP) halal tourism. This is done because the halal concept has now become a lifestyle for most Indonesian people. This type of research is library research, which is defined as the acquisition of data and information from library sources, such as books, studies, journals, and other reading materials relevant to the subject of this research. The study was conducted in Banyumas Regency and explained the concept of “one village, one product”. The survey results show that Banyumas Regency has enormous tourism potential, and there are opportunities to integrate the concept of OVOP-based halal tourism into Banyumas tourism, especially the development of cultural tourism, because Banyumas is known as a national hero city. Regions must have and develop their own unique identity that other regions do not have. This difference will increase the number of tourists visiting. This concept can be an example or role model for other regions in the management and development of halal tourism in the future.

This research aims to determine the level of performance of Islamic Commercial Banks in Indonesia using the Risk Based Bank Rating (RBRR) and Shariahh Conformity and Profitability (SCnP) for the 2017-2019 period. The object of this research is a BUMN Shariah Commercial Bank. The technique used for this research is purposive sampling using descriptive quantitative method. This study describes the performance of Islamic Commercial Banks through two methods, namely the Risk-Based Bank Rating (RBBR) method which is seen from 4 aspects, namely Risk Profile, Good Corporate Governance, Earnings, and Capital. The second method is Shariahh Conformity and Profitability (SCnP) which is seen from the Shariahh Conformity variable with indicators of Islamic Investment Ratio, Islamic Income Ratio, and Profit-Sharing Ratio and Profitability variable with indicators of Return on Assets (ROA), Return on Equity (ROE), and Net Profit Margin Ratio. The results showed that dwith the Risk-Based Bank Rating (RBBR) method, Islamic Commercial Banks are in a “Healthy” or “Good” condition. While the analysis using the Shariahh Conformity and Profitability (SCnP) method, shows that Islamic Commercial Banks are spread in three quadrants, namely URQ, LRQ, and ULQ.
