Background: Breast cancer (BC) metastases to the abdomen and pelvis
affect the liver, mesentery, retroperitoneum, peritoneum, bladder,
kidney, ovary, and uterus. The study documented the radiological pattern
and features of the chest, bone, abdominal and pelvic (AP) metastases
among advanced breast cancer patients. Materials and Methods: Chest,
abdominal and pelvic Computed Tomography (CT) scan images of 36 patients
with ABC were collated from Cape Coast Teaching Hospital and RAAJ
Diagnostics. The images were prospectively assessed for metastasis to
the organs of the chest, AP soft tissues and bones. Radiologic features
of metastasis of the lungs, liver, lymph nodes (LN), and bones were
documented. Patients’ demographics, clinical data and histopathology
reports were also collected. The data was captured using Uvosyo and
exported to Microsoft Excel templates. The data obtained were
descriptively analyzed. Results: Only 2.8% of BCs exhibited metaplastic
BC, while 97.2% had invasive ductal BC. Triple-negative cases was
55.6%. Of 36 patients, 31 (86.1%), 21 (58.3%) and 14(38.8%) were
diagnosed of chest, AP and bone tissues metastasis, respectively. LN
involvement was reported in 26 (72.2%) patients. Majority, 21 (58.3%)
were diagnosed of multiple sites metastasis with 15 (41.7%) showing
single site. Lungs (77.4%, 24/31), and liver (47.6%, 10/21) were the
most affected distant organs. Most bone metastases were lytic lesions
(92.9%, 13/14) with the vertebrae (85.7%, 12/14) been the most
affected. Conclusion: According to the study, advanced breast cancer
patients have a higher-than-average radiologic incidence of lung, liver,
bone, and lymph node metastases.
Safety and Psychotherapy Change Process: An Integrative Relational Approach
Authors: Gelo Omar , Podolan Martin
Published: August 2023

It is widely agreed that the psychotherapeutic relationship is crucial
for change. This paper contributes to the relational orientation by
exploring safety through a transtheoretical lens. We aimed to identify
and integrate those relational aspects of safety that are
school-independent and facilitate the psychotherapeutic change process.
Our comprehensive analysis showed that the relational aspects of safety
form a dynamic system involving the therapist, the client, and the
relationship. These interact, influence each other, and perform multiple
homeostatic functions: they allow to resist change, assimilate small
changes that do not disrupt the client’s way of functioning, regulate
major changes that disrupt and alter the client’s mode of functioning,
and also regulate adjustments in the way the therapist and client work
together. From an integrative-relational perspective, a safe therapist
is a precondition for co-creating a safe environment. This establishes
trust and fosters an affective bond providing additional sources of
safety to the therapeutic relationship and the client. However, to
promote change and growth, the relational aspects of safety must be
tailored for each client in terms of intensity, duration, timing, and
scope. Most importantly, they must be neither perfect nor steady but
rather sufficient and dynamic – leaving space for co-regulation of
tolerable frustrations, disappointments, and insecurities that
facilitate the client’s resilience and adaptation.

Published: August 2023

Although natural flooding plays a crucial role in shaping the
composition of aquatic communities, most rivers around the world have
been regulated or dammed for anthropogenic purposes. This affects the
biological and chemical composition of these ecosystems. Although
studies have demonstrated the negative effects of river regulation on
aquatic invertebrate communities globally, there is a scarcity of
research in Africa, despite its vulnerability to anthropogenic use. This
study aimed to compare aquatic invertebrate communities between the
regulated Phongolo River and the unregulated Usuthu River, South Africa
and to determine whether the largest lake in the region (Lake Nyamithi),
which receives water from both rivers, would show a stronger resemblance
to either of the two rivers. Aquatic invertebrate and water samples were
collected from 2012 to 2018 over several seasons. The Usuthu River
demonstrated a diverse and sensitive aquatic invertebrate community,
emphasising its high conservation value. Despite maintaining relatively
high aquatic invertebrate diversity, the Phongolo River demonstrated
effects of anthropogenic impact, with more resilient taxa to changes in
water quality and flow compared to the Usuthu River. Mismanagement and
excessive water use may lead to the loss of any remaining sensitive
aquatic invertebrate communities in this river. The presence of invasive
molluscan species such as Physella acuta and Tarebia granifera in the
Phongolo River and Lake Nyamithi also poses a threat to the aquatic
invertebrate community in the system. These invasive species are
currently absent from the Usuthu River although other invasive species,
such as the Australian redclaw crayfish, are found in both river
systems. Lake Nyamithi displayed a unique aquatic invertebrate
community, distinct from both rivers and their floodplains. This study
provides important baseline information on the Usuthu River’s aquatic
invertebrates and emphasises the need to maintain adequate water flow in
rivers and floodplains to protect biodiversity and sensitive species.
Evaluating the Representations of Atmospheric Rivers and Their Associated Precipitation in Reanalyses with Satellite Observations
Authors: Ma Weiming , Chen Gang , Guan Bin , Shields Christine A , Tian Baijun , Yanez Emilio
Published: August 2023

Atmospheric rivers (ARs) are filaments of enhanced horizontal moisture
transport in the atmosphere. Due to their prominent role in the
meridional moisture transport and regional weather extremes, ARs have
been studied extensively in recent years. Yet, the representations of
ARs and their associated precipitation on a global scale remains largely
unknown. In this study, we developed an AR detection algorithm
specifically for satellite observations using moisture and the
geostrophic winds derived from 3D geopotential height field from the
combined retrievals of the Atmospheric Infrared Sounder and the Advanced
Microwave Sounding Unit on NASA Aqua satellite. This algorithm enables
us to develop the first global AR catalog based solely on satellite
observations. The satellite-based AR catalog is then combined with the
satellite-based precipitation (Integrated Muti-SatellitE Retrievals for
GPM) to evaluate the representations of ARs and AR-induced precipitation
in reanalysis products. Our results show that the spreads in AR
frequency and AR length distribution are generally small across
datasets, while the spread in AR width is relatively larger. In terms of
the AR-induced precipitation, both AR-induced mean and extreme
precipitation are too weak nearly everywhere in reanalyses. However, all
reanalyses tend to precipitate too often under AR conditions, especially
over low latitude regions. This finding is consistent with the
“drizzling” bias which has plagued generations of climate models.
Overall, the findings of this study can help to improve the
representations of ARs and associated precipitation in reanalyses and
climate models.
Drivers of the Mixed Layer Salinity Seasonal Variability in the Arctic Ocean
Authors: Supply Alexandre , Lique Camille , Kolodziejczyk Nicolas , Talandier Claude
Published: August 2023

The processes driving the seasonal variability of the mixed layer
salinity in the Arctic Ocean are investigated using a simulation
performed with regional ocean – sea ice model at high resolution. While
the seasonal variations of the mixed layer depth remain small, in
particular under the perennial sea ice (O(30m)), the mean salinity of
the mixed layer varies largely, with a seasonal cycle as high as 3 pss.
On the shelves, where the sea ice is seasonal, the mixed layer is much
fresher but exhibits a seasonal cycle with a similar amplitude. Overall,
the seasonal variability of the mixed layer salinity results largely
from a 1D vertical balance between the freshwater flux at the surface
arising from the sea ice melt and freezing processes, and vertical
mixing and entrainment occurring at the base of the mixed layer. The
largest variations are found in summer, when the mixed layer is the
thinnest. Over the shelves, this simple 1D balance is complexified due
to the role of advection and river runoff that can locally affect the
mixed layer depth and salinity. Interestingly, the largest variations
are found less than 100km on each side of the sea ice edge, where all
the processes affecting the mixed layer are amplified. This suggests the
need to better observed and understand the ocean-sea ice-atmosphere
exchanges in these regions.
El entusiasmo bullicioso de los hinchas: sonido, espacio y sensaciones en los espectáculos deportivos en Chile, 1910-1949
Authors: Osorio Javier
Published: August 2023

Los espectáculos deportivos surgidos en la primera mitad del siglo XX, tales como los campeonatos regulares de fútbol y otras competencias deportivas, representan el tránsito de estas prácticas hacia la cultura de masas en el contexto de las políticas de reforma emanadas desde el Estado. Asimismo, estos eventos fueron instancias cotidianas de la experiencia popular, que encarnan la figura del hincha y sus formas de participación, las que fueron criticadas y celebradas en distintos momentos por la prensa, incorporando una escucha de los regímenes sensoriales relacionados con la producción del ruido y el grito colectivo. Mediante una lectura de periódicos y revistas especializadas, este artículo propone subrayar la función del sonido y las sensaciones en la conformación de los espectáculos deportivos en la cultura de masas en Chile durante este periodo. Para ello, la propuesta busca analizar la espacialidad del estadio y los componentes del paisaje sonoro, comprendiendo los regímenes de sentido y participación que relacionan los cuerpos, el sonido y la cultura. Se concluye la necesidad de escuchar al hincha, así como las prácticas colectivas que vinculan el sonido al desborde emocional de las masas, en el contexto de las transformaciones políticas y estéticas a través del siglo pasado.
Lectoras profanas: una exploración al fenómeno de la lectura de literatura en mujeres de los sectores populares
Authors: Duarte Acquistapace Deborah
Published: August 2023

El artículo propone explorar prácticas y experiencias de lectura de literatura de mujeres de sectores populares a partir de biografías de lectura. Los discursos de las lectoras coinciden en describir el acto de lectura a través del modelo del encantamiento, sin embargo, el modo de encantamiento descripto dialoga de manera crítica con las formulaciones referentes del campo: la “mala lectura” (Catelli, 1995; Batticuore, 2017), el “escape” (Radway, 1991) y las disposiciones ético prácticas (Bourdieu,2003; Lahire, 1993, 2004). Primero, el encantamiento no es pasivo, sino que implica la posibilidad de experimentar sensaciones y emociones. Los análisis feministas en torno a las respuestas afectivas a los textos (Radway, 2000; Pearce, 1997; Littau 2008 y Holmes, 2021) contribuyeron al análisis de este aspecto. Segundo, existe una búsqueda activa del estado a través de una serie de características de los textos susceptibles de habilitarlo que abordamos a partir de las herramientas de la “sociología del apego” (Hennion, 2012; Benzecry, 2012). Tercero, el estado de encantamiento, en tanto práctica con significación social, se presenta como un espacio de trabajo de la ipseidad, es decir, de la singularidad individual, a partir del conflicto o diferenciación con los roles definidos por las relaciones sociales (Dubet, 2010).

Penneførerrollen i FNs sikkerhetsråd: en mulighet for innflytelse
Authors: Nortvedt Jenny , Røysamb Maria Gilen
Published: August 2023

Som valgt medlem av FNs sikkerhetsråd i perioden 2021–2022 hadde Norge mulighet til å utgjøre en forskjell og yte innflytelse i verdens mektigste organ. I rollen som pennefører for Afghanistan gjorde Norge nettopp det. I løpet av medlemskapsperioden vedtok Sikkerhetsrådet å forlenge mandatet til FNs politiske oppdrag i Afghanistan (UNAMA), samt vedtok flere presseuttalelser og presidentuttalelser om situasjonen i Afghanistan. Bakteppet for den krevende jobben som pennefører var Talibans maktovertakelse i Afghanistan i august 2021 og Russlands angrepskrig mot Ukraina fra februar 2022. Med utgangspunkt i praksisteori og på bakgrunn av intervjuer med norske diplomater som forhandlet på vegne av Norge i FNs sikkerhetsråd, samt diplomater fra andre faste og valgte medlemsland, ser vi i denne artikkelen nærmere på den uformelle penneførerrollen i FNs sikkerhetsråd og Norges innsats som leder for arbeidet med Afghanistan. Artikkelen konkluderer med at penneførerrollen i FNs sikkerhetsråd er en av de sterkeste verktøyene for å oppnå innflytelse i enkeltsaker for valgte medlemsland, men er betinget av medlemslandenes diplomatiske kapital. Videre utgjør den uformelle praksisen også en mulighet til å fremme egne prioriteringer i Sikkerhetsrådet.
Abstract in English:Penholding in the UN Security Council: A Window of OpportunityAs an elected member of the UN Security Council between 2021 and 2022, Norway had the opportunity to achieve results within one of the world’s most powerful institutions. As a penholder on Afghanistan, Norway accomplished several important press statements, presidential statements and the 2022 extension of the United Nations Assistance Mission in Afghanistan (UNAMA). The context for this work was the seizure of power by the Taliban in Afghanistan in August 2021, and the invasion of Ukraine by the veto power Russia in February 2022. Based on interviews with Norwegian diplomats, and other elected and permanent members, this article investigates the informal penholder system in the UN Security Council. Furthermore, it looks into Norway’s role and experience as the penholder for Afghanistan. Practice theory brings insight to how an informal practice like penholding in the UN Security Council can provide influence for elected members if they know how to take advantage of this role. The article concludes that penholding is an important role for elected members in order to achieve influence in a specific case, but also to promote one’s own priority areas. However, influence through penholding is still conditioned by the country’s social capital, and goodwill from permanent members of the Security Council.

Two Tenses for All Sixteen Tenses: A Constructivist Approach
Authors: Pranoto Yohanes Heri , Fest Levinli Vewent
Published: August 2023

Getting to know and distinguishing the sixteen English tenses formula for some students, even college students, is not simple and straightforward. The construct of verb changes and modification in English is carefully considered one of the sources of the learning problem, and this concept – verb form changes - cannot be found in any Indonesian "dictionary". By means of conceiving the verb changes concept presented hierarchically (contractedly), comprehensively, simply, and fun, it is expected that the sixteen tenses formula can be facilely understood. This article aims at presenting descriptively (qualitatively) a learning design of sixteen English tenses with a constructivist approach. Those namely sixteen tenses formula are to be simplified through the classification of two tenses. Those two distinct tenses are namely present and past. All the English tenses are explained through the concept of the two tenses. The construct of present and past tenses is explained through understanding the minimum requirements for the formation of a sentence, namely the existence of a subject and predicate. Some of the previous research results are selected in order to elucidate the intended learning design.

MATHEMATICAL CRITICAL THINKING ABILITY BASED ON STUDENT’S SELF-EFFICACY USING PHENOMENOLOGICAL STUDY APPROACH
Authors: Umam Irfa Ul , Nurlaelah Elah , Suhendra Suhendra
Published: August 2023

Critical thinking is a key skill in terms of being used in most thinking processes. There is one variable related to critical thinking, namely self-efficacy. This can be seen from a positive significant relationship between self-efficacy and critical thinking. In this regard, this study aims to describe mathematical critical thinking abilities based on students' self-efficacy. This study uses a phenomenological approach. The researcher gave a self-efficacy questionnaire to class X students at a public high school in the city of Bandung, followed by giving tests on critical thinking skills, and conducted interviews with students with high self-efficacy (ST), medium self-efficacy (SS), and low self-efficacy (SR). The results show that ST belongs to high-level mathematical critical thinking skills in solving math problems. If students have high self-efficacy, so it will also have an impact on high critical thinking skills. SS is in the category of moderate-level critical thinking skills, thus showing that students with moderate self-efficacy do not necessarily have moderate-level mathematical critical thinking skills. SR cannot solve the given questions correctly and completely, so students with low levels of self-efficacy have low mathematical critical thinking skills.Kemampuan berpikir kritis menjadi kemampuan kunci yang digunakan pada proses berpikir. Literatur menunjukkan kemampuan berpikir kritis siswa masih perlu ditingkatkan. Oleh karenanya perlu dideskripsikan kemampuan berpikir kritis melalui variabel yang memoderatorinya. Terdapat salah satu variabel yang berkaitan dengan berpikir kritis, yaitu self-efficacy. Hal ini ditunjukkan dengan adanya hubungan positif yang signifikan antara self-efficacy dan berpikir kritis. Berkaitan dengan itu, tujuan penelitian ini untuk mendeskripsikan kemampuan berpikir kritis matematis berdasarkan self-efficacy siswa. Penelitian ini menggunakan pendekatan fenomenologi. Peneliti memberikan angket self-efficacy ke siswa kelas X di salah satu SMA Negeri di kota Bandung, dilanjutkan dengan memberikan tes kemampuan berpikir kritis, dan melakukan wawancara terhadap siswa dengan self-efficacy tinggi (ST), sedang (SS), dan rendah (SR). Hasil menunjukkan bahwa ST tergolong dalam kategori kemampuan berpikir kritis matematis tingkat tinggi dalam menyelesaikan soal matematika. Apabila siswa memiliki efikasi diri yang tinggi maka akan juga berdampak pada kemampuan berpikir kritis yang tinggi. SS berada pada kategori kemampuan berpikir kritis tingkat sedang, sehingga memperlihatkan bahwa siswa dengan kategori self-efficacy sedang belum tentu mempunyai kemampuan berpikir kritis matematis pada tingkat sedang pula. SR tidak dapat menyelesaikan soal yang diberikan dengan benar dan lengkap, sehingga siswa dengan tingkat self-efficacy rendah memiliki kemampuan berpikir kritis matematis yang rendah pula.

Kemampuan pemahaman konsep sangat dibutuhkan dalam proses pembelajaran matematika yang harus dikuasai untuk menunjang keberhasilan proses pembelajaran. Penelitian kuantitatif ini mengkaji kemampuan pemahaman konsep matematis siswa dengan mengimplementasikan model VARK-Fleming dan self-concept sebagai variabel kovariat. Penelitian ini bertujuan untuk mengetahui pengaruh model VARK-Fleming terhadap kemampuan pemahaman konsep matematis dengan mengontrol self-concept siswa dan pengaruh variabel kovariat self-concept terhadap kemampuan pemahaman konsep matematis siswa, serta pengaruh secara simultan model VARK-Fleming dan self-concept terhadap kemampuan pemahaman konsep matematis siswa. Partisipan dalam penelitian ini berjumlah 64 siswa SMP, dengan rincian 32 siswa belajar menggunakan model VARK-Fleming dan 32 siswa belajar dengan model ekspositori. Alat yang digunakan untuk mengumpulkan data adalah angket dan tes uraian. Pengujian hipotesis menggunakan analysis of covariance (one-way ancova). Hasil penelitian ini menunjukkan bahwa terdapat pengaruh lebih baik model pembelajaran VARK-Fleming dibandingkan model ekspositori dan self-concept terhadap kemampuan pemahaman konsep matematis siswa baik secara parsial maupun simultan.Â Concept understanding is required for the learning process to be successful. This quantitative study investigates students' mathematical concept understanding abilities using the VARK-Fleming model and self-concept as a covariate variable. The purpose of this research is to determine the effect of the VARK-Fleming model on students' ability to understand mathematical concepts by controlling for students' self-concept and the effect of the covariate variable of self-concept on students' ability to understand mathematical concepts, as well as the simultaneous concept of the VARK-Fleming model and self-concept on students' ability to understand mathematical concepts. Sixty-four junior high school students participated in this research, with 32 learning the VARK-Fleming model and 32 learning the expository model. Questionnaires and descriptive tests were employed to collect information. The analysis of covariance was utilized for hypothesis testing (one-way ANCOVA). The findings of this research reveal that the VARK-Fleming learning model has a better effect on students' mathematical concept understanding capacity than the expository model and self-concept, both partially and concurrently.

Metro City has diverse tourism potential with its natural, artistic, and cultural wealth, so tourist destinations and culinary places in Metro City are growing in quality and quantity. However, due to the lack of information about tourist places, the number of visitors to tourist destinations and culinary places does not increase significantly, so people must look for a single unit of information for each tourist and culinary destination. So we need information media to facilitate problem-solving in the form of tourist destination applications and culinary places for tourists. With this application, it is hoped to help the problems of tourists who have difficulty finding information about tourist destinations and culinary places in Metro City. The application is designed using the User Centered Design method. Based on the results of testing the level of user satisfaction, the design of the Metro City Visiting application is included in a perfect interval with an average proportion of 80% so that the design can be continued to the application development stage.

Sekarang ini perkembangan dalam upaya mewujudkan keadilan dalam dunia hukum saat ini terbukti sangat kompleks.Dalam kehidupan sehari-hari ada beberapa istilah yang digunakan untuk mengartikan profesi hukum. Dalam sistem peradilan berlaku asas fiksi hukum, yaitu setiap orang dianggap mengetahui hukum. Negara hukum memberikan kedudukan tertinggi terhadap undang-undang, menegaskan bahwa tidak seorangpun dapat menolak penerapan hukum, terlepas dari kedudukan dan kekuasaannya. Dalam Undang-Undang Nomor 18 Tahun 2003 Tentang Advokat, Advokat adalah orang yang berprofesi sebagai ahli hukum, baik di dalam maupun di luardi luar pengadilan yang memenuhi syarat-syarat menurut ketentuan undang-undang ini.Advokat wajib tunduk mematuhi aturan profesional profesi advokat dan peraturan dewan kehormatan asosiasi advokat. Putusan Dewan Kehormatan Asosiasi Advokat tidaklah mengenyamping kan pertanggung jawaban pidana jika pelanggaran terhadap kode etik profesi profesi advokat menyangkut dan mengandung unsur pidana. Dewan kehormatan pusat berwenang untuk memutuskan dan menjatuhkan sanksi terhadap pelanggaran yang dilakukan oleh anggota biasa (dari advokat aktif) perkumpulan, terhadap pelanggaran norma susila atau perilaku yang merendahkan harkat dan martabat advokat, atau perbuatan yang dapat mengurangi kepercayaan masyarakat terhadap profesi advokat.Kode etik profesi belum dapat diterapkan dengan maksimal. Hambatan atau kendala lainnya adalah: adanya penyalahgunaan profesi hukum; Menurunnya kesadaran dan kepedulian sosial serta sistem yang sudah ketinggalan zaman; kemajuan teknologi tidak dapat dibarengi dengan kemajuan yang pesat dibidang hukum sehingga menimbulkan perundang-undangan yang ketinggalan zaman; tidak ada komitmen untuk melakukan atau karena fungsi dan tujuan dari kode etik profesi tidak dipahami dengan jelas atau karena tidak mau melakukannya; sumber daya manusia (SDM).

Okra [Abelmoschus esculentus (L.) Moench] also known as bhindi or lady’s finger is an important vegetable crop in India, West Africa, South Africa, Brazil, USA and Turkey. It belongs to the family Malvaceae. Okra is mainly grown in tropics and subtropics of the world. The studies regarding the molecular marker development are very limited; still there is no SSR development from comprehensive transcriptome data in this crop. This study presents the first comprehensive transcriptome data, using RNA from different parts of okra such as root, stem, leaf, bud, flower, different stages of developing pod and from twenty days old plantlets of heat, drought and salt stressed. A total of 10,492 SSRs were identified in this study. Among these tri repeats (2112) were found to be predominant followed by di (1285), tetra (149), penta (24) and hexa. Thirty four SSRs were standardized for PCR and screened for 36 okra genotypes and accessions. Among these 18 SSR primers were found to be highly polymorphic with the PIC values more than 0.5. And the overall results of analysis showed that expected heterozygosity ranged from 0.000 to 0.971 with a mean of 0.593; the values for observed heterozygosity ranged from 0.000 to 0.794 with the mean of 0.254; the number of allele per locus ranged from 1 to 30 and the Polymorphic Information Content (PIC) ranged from 0.000 to 0.940 with the mean value of 0.5546. The genic SSR markers developed will help in germplasm characterization mapping, genetic diversity studies, molecular assisted breeding and also in gene discovery.

The plants and its produce characteristics are the basis to design a crop specific harvester. The objective of this study was to determine the physical, morphological and mechanical properties of chilli crop and fruits, that can be used in the design of harvester machine. The observations and data were collected by taking measurements at harvesting stage of three chilli cultivars. The fruit bearing behavior of plants was solitary with fruit position erect in Demon F1 and pendent in Araka Meghana and Mahyco Tejaswini. The plant height ranged between 81.76 to 84.87cm depending on cultivars and fruits per plant were170.25 number for Tejaswini, 158.96 and 156.15 number, respectively for Araka Meghana and Demon F1. It was observed that the length and diameter at shoulder of fruits was in the range of 4.97 to 10.44 cm and 0.8 to 1,25 cm, respectively. The moisture content reduced in leaves, stems and fruits as the maturation changed from matured green fruits bearing of plants to semi dry condition. The detachment force of fruits from plants increased as the fruits colour changed from matured green to fully ripened red and there after decreased.

Citrus rinds contain essential oils. One of the major constituents of the essential oils in the zest of different fruits like Citrus sinensis, C. limon, and Vitis vinifera is limonene. In this research, limonene was extracted by hydro-distillation method using Clevenger set up and its antimicrobial activity against certain bacterial and fungal strains was determined by using Kirby Bauer’s disc diffusion method. The primary antimicrobial screening of limonene without dilution exhibited a zone of inhibition (mm) comparable to Ampicillin (20mg/ml) and Amphotericin B (20mg/ml). The effect of pure limonene against all strains used was high as compared to the isolated samples. The MIC values also showed an expected decrease in the zone of inhibition from 1:2 to 1:8 dilutions. Based on this study, the cost-effective isolation of limonene and other essential oils is quite possible.
